Referring to fig. 1, a computing terminal 200 establishes data connections with a cloud server 300 and at least one sensing terminal 100, respectively. Preferably, the computing terminal 200 may be connected to more than two sensing terminals 100 at the same time.

The first acceleration sensing component 120 and the second acceleration sensing component 160 of the sensing terminal 100 can acquire vibration data of a target object (such as a wind turbine generator system blade). Because the material property of the generator set equipment can be affected by temperature, for example, the connecting part of the fan blade and the rotating shaft of the generator set generates heat due to rotation friction, the temperature sensing component 130 is further arranged on the sensing terminal 100 for eliminating the temperature factor.

Preferably, in order to perform data acquisition under different use environments, the sensor terminal 100 of the embodiment is provided with two models, namely a wired sensor terminal 101 shown in fig. 2 and a wireless sensor terminal 102 shown in fig. 3. The wired sensing terminal 101 can transmit collected data through a data line connected to the communication port 220. Preferably, the communication ports 220 include a high speed communication port 221 and a low speed communication port 222. The wireless sensing terminal 102 can transmit the collected data to the computing terminal 200 for computational analysis in a wireless transmission manner through the configured first Lora communication unit 170.

The data in the single axial direction of the alternating current collected by the second acceleration sensor 161 needs to pass through the filter 162, the voltage follower 163 and the high-speed ADC164 in sequence and then is transmitted to the processing module 110 through the communication protocol interface for processing. Preferably, the first acceleration sensing assembly 120 may include a first acceleration sensor. Preferably, the processing module 110 includes a processing chip 111, a random access memory 112, and a read only memory 113. The processing chip 111 is electrically connected to the random access memory 112 and the read only memory, respectively.

The computing terminal 200 of this embodiment receives the vibration data of the target object collected by the sensing terminal 100, performs calculation and analysis based on the vibration data to obtain analysis results such as vibration speed, vibration amplitude, vibration spectrum, and the like, and transmits the analysis results to the cloud server to implement supervision on the target object.

Referring to fig. 4, the computing terminal 200 includes a computation analysis module 210, a communication port 220, a second Lora communication unit, and a 4G communication unit. The communication port 220, the second Lora communication unit and the 4G communication unit are electrically connected with the calculation and analysis module 210, respectively. The computing terminal 200 receives the data collected by the sensing terminal 100 through the second Lora communication unit 230 or the communication port 220. The second Lora communication unit 230 or the communication port 220 transmits the received data to the calculation and analysis module 210 for calculation and analysis. The calculation and analysis module 210 performs calculation and analysis through a preset program in response to the received data to obtain an analysis result at least including motion state parameters such as vibration speed, vibration amplitude, vibration frequency spectrum and the like. The calculation analysis module 210 transmits the analysis result to the 4G communication unit 240 and transmits the analysis result to the cloud server 300 through the 4G communication network. In other words, the computing terminal 200 establishes communication with the cloud server 300 by using the configured 4G communication unit 240, and uploads a computational analysis result generated after the computing terminal 200 performs computational analysis on data collected by the sensing terminal 100 and received by the configured second Lora communication unit 230 or the configured communication port 220 to the cloud server 300. The sensing terminal 100 acquires data of a target object and transmits the acquired data to the computing terminal 200 in a wired or wireless data transmission manner. The computing terminal 200 analyzes the motion of the object by performing computation analysis on the data collected by the sensing terminal 100. The computing terminal 200 transmits the analysis result of the object motion to the cloud server 300 by means of the configured 4G communication unit 240. Preferably, the communication ports 220 include a high speed communication port 221 and a low speed communication port 222. Preferably, the high-speed communication port 221 may be an IEEE 1588PoE high-speed interface. Preferably, the low-speed communication port 222 may be an RS485 low-speed interface.

Preferably, the sensing terminal 100 preferably employs the wired sensing terminal 101 in an environment suitable for wired power supply without considering power consumption and with a real-time requirement on data. The wired sensing terminal 101 can be connected with the wired sensing terminal 101 through the communication port 220 in a wired manner, and data of the wired sensing terminal 101 is received and calculated and analyzed, so that the real-time performance of object motion analysis is guaranteed. Preferably, the wired sensing terminal 101 can establish real-time data connection with the computing terminal 200 by means of wired connection of the communication port 220 to the computing terminal 200, so as to directly transmit the collected data to the computing terminal 200 in real time for computational analysis.

The wireless sensing terminal 102 is preferably employed where the real-time requirements for data are low and a large number of deployed sensors are required. Preferably, the model of the wireless sensing terminal 102 of the sensing terminal 100 can directly establish wireless communication with the second Lora communication unit 230 configured on the computing terminal 200 through the configured first Lora communication unit 170, so as to directly transmit the collected data to the computing terminal 200 for computation and analysis. Preferably, in a use environment where it is necessary to deploy the sensing terminal 100 in a wide range and it is inconvenient to deploy the data transmission line, the wireless sensing terminal 102 may transmit data required for the object motion analysis to the computing terminal 200 using the configured second Lora communication unit 230.

Preferably, in a usage environment requiring a plurality of sensing terminals 100 to acquire data synchronously and having low power consumption, the system of the embodiment may be deployed by connecting at least one wired sensor 101 to the repeater 400 through the communication port 220 by wire, and then the repeater 400 establishes wireless communication with the second Lora communication unit 230 configured on the computing terminal 200 through the configured third Lora communication unit 410 to transmit the data acquired by the wired sensor 101 to the computing terminal 200 for computational analysis. Preferably, two or more wired sensing terminals 101 are wired to the repeater 400 through the communication port 220. The repeater 400 establishes wireless communication with the second Lora communication unit 230 configured by the computing terminal 200 through the configured third Lora communication unit 410. The repeater 400 receives data collected by the plurality of wired sensing terminals 101 in a wired communication mode, and then transmits the received data to the computing terminal 200 in a wireless communication mode for computational analysis, so that the synchronism of the plurality of sensing terminals 100 is guaranteed. And because the power consumption of the repeater 400 is lower than that of the computing terminal 200, and the Lora communication unit in the system can be selectively turned on (started when data transmission is needed and dormant when the data transmission is not needed). Compared with the way that the computing terminal 200 continuously opens the communication port 220 to receive the data collected by the wired sensing terminal 101, the data transmission way of the repeater 400 is adopted, so that the power consumption of the system can be reduced. Referring to fig. 5, the repeater 400 is provided with a third Lora communication unit 410 and a low-speed communication port 222. The reason why only the low-speed communication port 222 is provided is that the communication speed of the repeater 400 in the Lora communication is significantly lower than that of the wired communication, and does not meet the high-speed communication requirement, and therefore the repeater 400 is not provided with the high-speed communication port 221.

The first acceleration sensing assembly 120 and the second acceleration sensing assembly 160 are disposed on the same plate body in a manner that they are axially flush with each other such that the collected data are aligned, which is convenient for the processing module 110 to process the data collected by the first acceleration sensing assembly 120 and the second acceleration sensing assembly 160. Specifically, referring to fig. 5, the first acceleration sensor of the first acceleration sensing assembly 120 and the second acceleration sensor 161 of the second acceleration sensing assembly 160 are disposed on the same plate body in an axially aligned manner. Preferably, after the first acceleration sensing assembly 120 and the second acceleration sensing assembly 160 are disposed on the same plate body in an axis alignment manner, at least one reference parameter is the same when the first acceleration sensing assembly 120 and the second acceleration sensing assembly 160 perform data acquisition, so that the processing module 110 of the terminal 100 performs fusion processing on data from different sensing assemblies. Preferably, the core components of the first acceleration sensing assembly 120 and the second acceleration sensing assembly 160 both include accelerometers. In the sensing terminal 100 of this embodiment, a plurality of sensing components using accelerometers as core devices may be arranged on a board body of the same circuit structure in an axis alignment manner, so that at least one parameter (for example, position height, relative coordinate, etc.) of the sensing components is the same, and thus parameters to be processed when the processing module 110 of the sensing terminal 100 and the computing terminal 200 perform fusion processing on data collected by the sensing components can be reduced, the implementation is fast, and the time spent in performing object motion analysis in the present invention is indirectly reduced through the processing. Preferably, the first acceleration sensing unit 120 and the second acceleration sensing unit 160 are disposed on the plate body at positions far from the surrounding mechanical mounting holes, so as to prevent external stress from being transmitted to the sensors. The sensing terminal 100 of the embodiment places each sensing component on the circuit board in the middle, so that the inaccuracy of the data acquisition result of the sensing component caused by the fact that the stress generated by the circuit board is transferred to the sensing component placed on the circuit board due to the fact that the sensing terminal 100 is packaged is avoided.

Preferably, the processing module 110 receives the data transmitted by the sensing assembly through the interface, and thus processes the received data. Fig. 7 is a circuit diagram of a processing chip of the processing module 110. Preferably, the processing chip 111 may be STM32F446ZET6. FIG. 8 is a circuit schematic of a preferred RAM 112 of the sensor terminal 100 of the present invention. Preferably, the random access memory is a RAM chip including at least SDRAM and PSRAM. Preferably, the random access memory 112 may be an SDRAM. Preferably, the processing module 110 integrates a 2Mbytes high capacity SDRAM chip. Preferably, the SDRAM power supply is controllable, and the power consumption of the system is reduced when the data is not collected. When the waveform data needs to be collected, the large-capacity storage unit is needed to store the waveform data, and at this time, the processing module 110 turns on a power switch of the large-capacity PSRAM chip. Fig. 9 is a circuit diagram of a preferred rom 113 of the terminal 100 of the present invention. Preferably, the read only memory 113 may be FLASH. Preferably, the read only memory 113 is connected to the processing module 110 by an interface. Preferably, the interface may be an SPI interface and/or an I/O interface. Preferably, the power supply of the read only memory 113 can be controlled by a signal. In the case where the read only memory 113 is not used, the sensing terminal 100 can cut off the power supply to the read only memory 113.

The processing module 110 has at least a first state and a second state different from the first state. The first acceleration sensing component 120 can control the enabling/disabling of the second acceleration sensing component 160 by controlling the processing module 110 to switch between the first state and the second state. In particular, for the wireless sensing terminal 101, the first acceleration sensing component 120 can further control the activation/sleep of the Lora communication unit 170 by controlling the switching of the first state and the second state of the processing module 110. In actual deployment, in order to reduce power consumption of the sensing terminal 100, the second acceleration sensing component 160 and/or the Lora communication unit 170 are/is in a sleep state by default, the processing module 110 is in a first state where only part of the components are in operation, and the first acceleration sensing component 120 is in a normal operation state. The processing module 110 enters the second state from the first state if and only if the data collected by the first acceleration sensing assembly 120 is abnormal. The processing module 110 entering the second state uses the data collected by the preset program from the first acceleration sensing assembly 120 and determines whether to turn on the second acceleration sensing assembly 160 and/or the Lora communication unit 170. When the data collected by the first acceleration sensing component 120 is not abnormal, a large number of components (such as the second acceleration sensing component 160 and the Lora communication unit 170) of the sensing terminal 100 are in a dormant state, so that the sensing terminal 100 can collect the data with low power consumption.

Preferably, the processing module 110 can switch the power of the ram 112 and the rom 113 by switching between the first state and the second state. Preferably, when the power of the ram 112 and the rom 113 is turned on, the processing module 110 can process and transmit the data collected by the sensing component with the highest performance, so that the subsequent computing terminal 200 can perform calculation and analysis on the motion of the object. The processing chip 111 is electrically connected to the random access memory 112 and the read only memory, respectively. If and only if the processing module 110 is in the second state, the processing chip 111 will send a signal to turn on the power of the ram 112 and the rom 113 to operate. When the processing module 110 is in the first state, the processing chip 111 powers off the ram 112 and the rom 113 through the electrical signal to make them sleep, so as to avoid the ram 112 and the rom 113 from generating power consumption under the non-working condition, so that the power consumption of the whole terminal 100 is high. Preferably, the first state of the processing module 110 is a sleep state, and the second state of the processing module 110 is an operating state. The processing module 110 may control the power supply of the first acceleration sensing assembly 120, the second acceleration sensing assembly 160, and/or the Lora communication unit 170 through the interface. When the processing module 110 is in the first state, in order to reduce the power consumption of the terminal 100, the processing module 110 sends a signal through the interface to cut off the power supply of the second acceleration sensing assembly 160 and/or the Lora communication unit 170, so that the second acceleration sensing assembly 160 and/or the Lora communication unit 170 enters the sleep mode. When the second acceleration sensing component 160 and/or the Lora communication unit 170 are dormant, the processing module 110 can send a signal through the interface to turn on the power supply of the first acceleration sensing component 120, and it is ensured that the first acceleration sensing component 120 can normally and stably work, so that the terminal can reduce power consumption under the condition of satisfying data acquisition. Preferably, in the case that the processing module 110 is in the first state, the processing module 110 can turn off the power supply of the second acceleration sensing assembly 160 and the Lora communication unit 170 and turn on the power supply of the first acceleration sensing assembly 120, so that the sensing terminal 100 can operate with the lowest power consumption.

Fig. 10 is a schematic circuit diagram of a preferred first acceleration sensing assembly 120. Preferably, the MEMS high-frequency acceleration sensor adopts a high-frequency acceleration sensor KX132. The sensor is specially designed for high-frequency vibration analysis, the output frequency of the sensor is up to 25.6KHz, the output bandwidth is up to 8.2KHz, and compared with the traditional acceleration sensor, the high-frequency acceleration sensor used in the invention has better high-frequency vibration measurement effect, and the accuracy of analyzing the vibration frequency through the acceleration signal of the sensor is higher. Preferably, the first acceleration sensing component 120 and the second acceleration sensing component 160 are configured to be driven by current through the I/O port of the processing module 110 to control on/off. After being awakened by the first acceleration sensing component 120, the processing module 110 of the sensing terminal 100, which is integrated with multiple sensing components, can supply power to the second acceleration sensing component 160 through the I/O port of the second acceleration sensing component 160 by running a preset program, so that the second acceleration sensing component 160 is started to enable the second acceleration sensing component 160 to perform data acquisition. As shown in fig. 5, the power supply of the first acceleration sensing assembly 120 may be controlled by a signal. Preferably, the processing module 110 can send a signal through the interface to turn on or off the power supply of the first acceleration sensing assembly 120. The technician deploying the terminal 100 sets a corresponding response threshold for the first acceleration sensing component 120 by analyzing the data that needs to be sensed in the field. Preferably, in case that the data collected by the first acceleration sensing component 120 exceeds a preset threshold, the first acceleration sensing component 120 generates an interrupt signal and transmits the interrupt signal to the processing module 110 through an interface connected with the processing module 110 so as to wake up the processing module 110. After receiving the interrupt signal, the processing module 110 enters the second state from the first state to wake up. Preferably, when the data collected by the first acceleration sensing component 120 exceeds the preset threshold, it is determined that the collected data is abnormal, and the processing module 110 needs to be requested to determine the abnormality, so that the processing module 110 generates an interrupt signal and transmits the interrupt signal to the processing module 110 through an interface connected to the processing module 110. The processing module 110 enters a second state with higher power consumption in which all the devices operate in response to the "reception of the interrupt signal" from the first state with low power consumption in which some of the devices are dormant, and analyzes data collected by the first acceleration sensing assembly 120. Preferably, the terminal 100 can make the processing module 110 enter the second working state with higher power consumption when the data collected by the first acceleration sensing component 120 needs to be analyzed, and the processing module 110 is in the first working state with low power consumption when the data collected by the first acceleration sensing component 120 does not need to be analyzed, so that the processing module 110 is prevented from being always in the second working state with higher power consumption when the terminal 100 performs long-term data collection, and further, the power consumption of the terminal 100 during data collection is reduced.

Preferably, the temperature sensing assembly 130 configured with the sensing terminal 100 is connected to the processing module 110 through an interface. The temperature sensing assembly 130 transmits the measured temperature data to the processing module 110 through an interface. FIG. 6 is a schematic circuit diagram of a preferred temperature sensing assembly. Preferably, the temperature sensing component 130 may be a MEMS temperature sensor. Preferably, the MEMS temperature sensor employs DS18B20. In the case where the temperature sensing component 130 is not needed, the power supply of the temperature sensing component 130 is turned off, thereby reducing the system power consumption. As shown in fig. 11, the power supply of the sensing assembly may be controlled by a signal. Preferably, the processing module 110 can send a signal through the interface to control the power mode of the temperature sensing assembly 130. Preferably, the processing module 110 can turn off the power supply of the temperature sensing assembly 130 under the condition of not sensing the temperature, thereby reducing the system power consumption. Preferably, a technician at the deployment terminal can set the operation of the temperature sensing assembly 130 based on an analysis of the target object. Preferably, the temperature sensing assembly 130 may operate in a manner that the processing module 110 enters the second state and then sends a signal to enable the temperature sensing assembly 130 to normally supply power, so that the temperature sensing assembly 130 starts to operate to collect data.

Fig. 12 shows a preferred second acceleration sensing assembly 160 circuit. The second acceleration sensor 161 outputs an analog signal, which is sampled by the filter 162, the voltage follower 163, and the high-speed ADC164, and then output to the processing module 110 for processing. Referring to fig. 12, after the processing module 110 powers on the second acceleration sensor through the second acceleration sensor power control circuit 165, the second acceleration sensor 161 passes through the filter 162 and the voltage follower 163, and then the voltage signal of the second acceleration sensor 161 is sampled through the high-speed ADC164, and is connected to the processing module 110 through the SPI bus, so that the voltage signal of the second acceleration sensor 161 is collected, and the system of the second acceleration sensing assembly 160 is highly integrated. Preferably, the second acceleration sensor 161 may be an ADXL100X series MEMS-IEPE chip. Preferably, the filter 162 may be a band-limiting filter. Preferably, the band-limiting filter circuit is mainly composed of an operational amplifier and at least one resistor and at least one capacitor. Preferably, the voltage follower 163 is composed of at least two operational amplifiers. Preferably, the operational amplifier may be OPA4325. Preferably, the high speed ADC chip may be MCP3561. The ADXL100X chip has the lowest noise at a supply voltage of 5V. To improve the data acquisition accuracy of the second acceleration sensing assembly 160, the present embodiment controls the power supply to the ADXL100X by the second acceleration sensor power control circuit 165. Fig. 13 is a schematic diagram of a preferred second acceleration sensor power control circuit of the terminal of the present invention. The MEMS-IEPE chip is connected with a band-limiting filter at the rear stage, so that the accuracy of the high-frequency response of the sensor is improved. And the high-speed ADC164 unit supplies power to 3V3. The output of the amplifier is divided by the band-limiting filter circuit through the resistors and then output to the voltage follower, so that the 5V signal is linearly reduced to a range of 3V3, and after passing through the voltage follower 163, the impedance of the MEMS-IEPE chip signal is reduced, so that the high-speed ADC164 is more accurate in sampling. Referring to fig. 13, preferably, the processing module 110 sends a signal to cut off the power supply of the first acceleration sensing component 120 through the interface in case the second acceleration sensing component 160 is enabled. Preferably, the second acceleration sensing assembly 160 is capable of collecting data at a higher frequency than the first acceleration sensing assembly 120. Data distortion and other problems can occur when data with a frequency range suitable for the second acceleration sensing assembly 160 is collected by the first acceleration sensing assembly 120, data distortion and other problems can also occur when data with a frequency range suitable for the first acceleration sensing assembly 120 is collected by the second acceleration sensing assembly 160, in order to avoid data distortion and other problems and the problem that the power consumption of the terminal 100 is high as the first acceleration sensing assembly 120 and the second acceleration sensing assembly 160 are opened simultaneously, the processing module 110 cuts off the power supply of the first acceleration sensing assembly 120 under the condition that the second acceleration sensing assembly 160 is started, and therefore the terminal 100 can conduct accurate data collection with low power consumption.

Fig. 14 is a simplified circuit schematic diagram of the first Lora communication unit 170 according to a preferred embodiment of the present invention. The wireless sensing terminal 102 in this embodiment is provided with a first Lora communication unit 170.

Under the condition that the first Lora communication unit 170 is not used, the processing module 110 turns off the power supply of the first Lora communication unit 170 through a signal, and the power consumption of the system is reduced. Preferably, the power supply of the first Lora communication unit 170 is controlled by a signal of the processing module 110. The processing module 110 opens the first Lora communication unit 170 only when data transmission is needed, and then transmits the data to the computing terminal 200 that has been on for Lora signal reception. Preferably, the first Lora communication unit 170 employs a Lora module of the ra-01s type. The Lora module of ra-01s model can be used for ultra-long distance spread spectrum communication, and interference immunity is strong, can furthest reduce current consumption. Preferably, the processing module 110 in the second state can receive and process the data collected by the first acceleration sensing assembly 120 and/or the second acceleration sensing assembly 160 through the interface and send the processed data to the computing terminal 200 through the first Lora communication unit 170. Preferably, the interface may be an SPI interface and/or an I/O interface. Preferably, after the processing module 110 processes the data collected by the first acceleration sensing component 120 and/or the second acceleration sensing component 160, the processed data must be sent to the computing terminal 200 through the first Lora communication unit 170. Preferably, the processing module 110 turns on the power of the first Lora communication unit 170 through the interface only when the processed data needs to be transmitted to the computing terminal 200 through the first Lora communication unit 170, and activates the first Lora communication unit 170 so that the data processed by the processing module 110 can be transmitted to the computing terminal 200. After the first Lora communication unit 170 completes data transmission, the processing module 110 turns off the power of the first Lora communication unit 170, so that the first Lora communication unit 170 enters into sleep. The sensing terminal 100 of this embodiment enables the first Lora communication unit 170 when data needs to be sent to the computing terminal 200, and enables the first Lora communication unit 170 to go to sleep at other times, thereby avoiding power consumption waste caused by continuous opening of the first Lora communication unit 170, reducing power consumption when the sensing terminal 100 performs data acquisition, and further reducing power consumption of the mechanical failure diagnosis and predictive maintenance system provided by this embodiment.

Preferably, the second acceleration sensing assembly 160 is in a dormant state when the sensing terminal 100 is initially installed to collect data of a target object. If and only when the first acceleration sensing component 120 disposed in the sensing terminal 100 sends an instruction to the processing module 110 of the sensing terminal 100, which requires to wake up the second acceleration sensing component 160, the processing module 110 will wake up the second acceleration sensing component 160 for data acquisition. Preferably, when the second acceleration sensing component 160 collects data, the computing terminal 200 performs a computational analysis of the object motion based on the data collected by the second acceleration sensing component 160.

Preferably, the sensing terminal 100 of the present mechanical failure diagnosis and predictive maintenance system can change the power-on state of the sensing component according to the collected data. The sensing terminal 100 provides accurate data so that the mechanical failure diagnosis and predictive maintenance system of the present embodiment can collect sensing data with the lowest power consumption when the motion analysis of the object is possible.

The civil engineering structure safety monitoring and early warning system provided by the embodiment comprises a sensing terminal 100, a computing terminal 200 and a cloud server 300. The sensing terminal 100 may collect characteristic data of the civil engineering structure such as acceleration data, inertia data, inclination data, and the like. The computing terminal 200 calculates and analyzes the characteristic data including the characteristics of the civil engineering structure such as acceleration, inertia and inclination angle collected by the sensing terminal 100 to obtain the structure vibration condition, attitude change, motion trail and the like of the civil engineering. The computing terminal 200 uploads the calculation analysis result to the cloud server 300 to realize safety monitoring and early warning of the civil engineering structure.

The sensing terminal 100 can be configured with sensing components including a first acceleration sensing component 120, a second acceleration sensing component 160, an inertial measurement sensing component 140, and a tilt sensing component 150. Referring to fig. 15, the first acceleration sensing assembly 120, the second acceleration sensing assembly 160, the inertial measurement sensing assembly 140, and the tilt sensing assembly 150 are each connected to the processing module 110 via an interface. The second acceleration sensing assembly 160, the inertial measurement sensing assembly 140, and the tilt sensing assembly 150 are capable of data acquisition, either directly or indirectly in response to instructions generated by the first acceleration sensing assembly 120 based on changes in the acquired data.

Preferably, the inertial measurement sensing assembly 140 of the terminal 100 is configured to interface with the processing module 110. The inertial measurement sensing assembly 140 transmits the measured trajectory data to the processing module 110 via an interface. Preferably, the interface may be an interface supporting the SPI communication protocol. FIG. 7 is a circuit schematic of a preferred inertial measurement sensing assembly. Preferably, the inertial measurement sensing component 140 may be a MEMS inertial measurement sensor. Preferably, the MEMS inertial measurement sensor employs a 6-axis sensor BMI085. The 6-axis sensor integrates acceleration and angular velocity sensors, and the noise of the acceleration is lower than that of the acceleration

Noise at angular velocity lower than

The invention uses the 6-axis sensor to independently analyze the motion track of the object, the angular velocity and the axial direction of the acceleration are calibrated when the chip leaves a factory, and the analysis accuracy of the motion track is higher. As shown in fig. 7, the power to the inertial measurement sensing assembly 140 can be controlled by a signal. In practical use, the processing module 110 can determine whether the inertia measurement sensing assembly 140 is powered according to whether the inertia analysis is required, so as to reduce the power consumption of the system. Preferably, the processing module 110 is capable of sending a signal via the interface to cause the inertial measurement sensing component 140 to enter a sleep or power-off state. Preferably, the processing module 11 is implemented without the use of a sensing assembly0 can turn off the power supply of the inertial measurement sensing component 140, reducing the power consumption of the system.

Preferably, the tilt angle sensing assembly 150 configured with the sensing terminal 100 is connected with the processing module 110 through an interface. The tilt sensing assembly 150 transmits the measured attitude data to the processing module 110 via an interface. Preferably, the communication protocol may be an SPI communication protocol. FIG. 17 is a circuit schematic of a preferred tilt angle sensing assembly. Preferably, the tilt sensing assembly 150 may be a MEMS tilt sensor. Preferably, the MEMS tilt sensor employs the tilt sensors SCL3300-D01. The measured angle precision reaches 0.0055 degrees, and the noise is lower than

The sensor is internally calibrated, and the calculation accuracy is higher than that of the traditional acceleration sensor. As shown in fig. 17, the power supply of the inclination sensing assembly 150 may be controlled by a signal. The processing module 110 can turn off the power supply of the tilt angle sensing assembly 150 without performing the attitude analysis, thereby reducing the power consumption of the system. In the case that the attitude analysis is required, the processing module 110 can turn on the power supply of the tilt angle sensing assembly 150, so that the terminal can sense the tilt angle data. The processing module 110 sends a signal to enable the tilt angle sensing assembly 150 to normally supply power, and then the tilt angle sensing assembly 150 starts to work to collect data. The inclination angle sensing component 150 sends the collected data to the processing module 110 through the SPI or other IO port, and the processing module 110 transmits the data to the computing terminal 200 for calculation and analysis through a wired or wireless communication mode. Under the condition that the sensing assembly is not used, the processing module 110 can turn off the power supply of the inclination angle sensing assembly 150, so as to reduce the power consumption of the system.

Preferably, the first acceleration sensing assembly 120 can set both a first threshold and a second threshold higher than the first threshold. Preferably, after the first acceleration sensing component 120 switches the first state of the processing module 110 to the second state through the interrupt signal, the processing module 110 processes the data collected by the first acceleration sensing component 120 and received through the interface through a preset program, and simultaneously evaluates and confirms whether to activate the second acceleration sensing component 160. When the threshold acquired by the first acceleration sensing component 120 is lower than the first threshold, the first acceleration sensing component 120 does not generate an interrupt signal to switch the first state of the processing module 110 to the second state. When the threshold value acquired by the first acceleration sensing component 120 is higher than the first threshold value and lower than the second threshold value, the first acceleration sensing component 120 can accurately acquire data, but the processing module 110 is required to process the acquired data, and at this time, the processing module 110 does not need to start the second acceleration sensing component 160. When the threshold value acquired by the first acceleration sensing component 120 is higher than the second threshold value, the first acceleration sensing component 120 cannot accurately acquire data, and the processing module 110 needs to start the second acceleration sensing component 160 to acquire data. The combined use of the first acceleration sensing component 120 and the second acceleration sensing component 160 can realize data acquisition in a wider range than that of a single acceleration sensing component, but the use of the first acceleration sensing component 120 and the second acceleration sensing component 160 at the same time can generate higher power consumption, and the power consumption of the terminal 100 can be reduced while realizing data acquisition in a wider range by the aforementioned manner of calling the acceleration sensing components in a hierarchical manner. Preferably, the second acceleration sensing assembly 160 is in a sleep state when the processing module 110 is in the first state. The second acceleration sensing assembly 160 is in an operational state when the processing module 110 is in the second state. When the processing module 110 is in the first state, the data required for analyzing the motion of the object is collected by the first acceleration sensing component 120. The processing module 110 in the second state collects data required for the motion analysis of the object through the second acceleration sensing assembly 160.

Preferably, the inertial measurement sensing component 140 may operate in a manner that the processing module 110 enters the second state in response to an interrupt generated by the first acceleration sensing component 120, and after the processing module 110 enters the second state, the processing module sends a signal to normally supply power to the inertial measurement sensing component 140, so that the inertial measurement sensing component 140 starts to operate to collect data and send the collected data to the processing module 110 through the interface for processing. Preferably, the processing module 110, after entering the second state, sends a signal to energize the inertial measurement sensing assembly 140 normally while sending a signal to energize the tilt sensing assembly 150 normally for tilt data measurement of the civil engineering structure for subsequent attitude analysis of the civil engineering structure by the computing terminal 200.

Preferably, since the civil engineering structure is susceptible to temperature (such as expansion and contraction), the sensing terminal 100 of the safety monitoring and warning system for civil engineering structure provided by the embodiment integrates the temperature sensing component 130 to eliminate the interference caused by the temperature factor when the computing terminal 200 performs the calculation analysis.

Preferably, the components of the cloud server 300, the computing terminal 200, the temperature sensing component 130, the first acceleration sensing component 120, the second acceleration sensing component 160, the processing module 110, and the like, and the components connected thereto in this embodiment are the same as those in embodiment 1, and are not described herein again.

1 and 2, and repeated details are not repeated. In this embodiment, the general object motion analysis system based on the intelligent motion sensing terminal provided by the invention can be a marine disaster monitoring and early warning system. The marine disaster monitoring and early warning system provided by the embodiment comprises a sensing terminal 100, a computing terminal 200 and a cloud server 300. The sensing terminal 100 of the general object motion analysis system has a track data acquisition function, the general object motion analysis system can be applied to the field of marine disaster monitoring and early warning to acquire marine wave height data, the computing terminal 200 calculates and analyzes 1/3 wave height and 1/10 wave height data based on the data acquired by the sensing terminal 100, and uploads the data exceeding an early warning value to the cloud server 300, so that the marine disaster monitoring and early warning function is realized.

In the field of marine disaster monitoring and early warning, disaster monitoring and early warning are generally performed by monitoring the ocean wave height. The traditional ocean wave height monitoring mode needs to deploy a water pressure sensor to the sea bottom, install detection equipment on a buoy, and calculate the height of the water surface by measuring the pressure of the water pressure sensor so as to realize the ocean wave height monitoring. The traditional mode construction period is long, and water pressure sensor's cost is higher, is not convenient for extensive deployment. The marine disaster monitoring and early warning system of this embodiment uses integral type motion sensing terminal 100 to gather the trajectory data of buoy, through calculation terminal 200 analysis buoy movement trajectory, calculates the ocean wave height, and calculation terminal 200 uploads the computational analysis result to cloud server 300 and realizes marine disaster and early warning. Compared with the traditional monitoring and early warning scheme based on the water pressure sensor, the system has lower cost and is convenient for large-scale deployment.

The sensing terminal 100 adopted by the marine disaster monitoring and early warning system at least comprises a sensing component and a processing module 110. Preferably, the sensing terminal 100 incorporates at least two sensing components, a first acceleration sensing component 120 and an inertial measurement sensing component 140. The first acceleration sensing component 120 and the inertial measurement sensing component 140 are respectively connected to the processing module 110 of the sensing terminal 100 through an interface. The processing module 110 has at least a first state and a second state different from the first state. The first acceleration sensing component 120 can control the activation or deactivation of the inertial measurement sensing component 140 by controlling the switching of the first state and the second state of the processing module 110.

The first state of the processing module 110 is a sleep state, and the second state is an operating state. The sensing terminal 100 adopted by the marine disaster monitoring and early warning system is further provided with a first Lora communication unit 170. Preferably, the sensing terminal 100 adopted by the marine disaster monitoring and early warning system is a wireless sensing terminal 102. The first Lora communication unit 170 is connected to the processing module 110 through an interface. The processing module 110 can transmit data to the first Lora communication unit 170 through an interface. The processing module 110 may also control the power supply of the first Lora communication unit 170 through an interface. The first acceleration sensing assembly 120 can indirectly control the activation or the sleep of the first Lora communication unit 170 by controlling the switching of the first state and the second state of the processing module 110.

Preferably, in actual deployment, in the initial state, the processing module 110 is in the first state so that the first acceleration sensing component 120 is normally powered through the interface. The processing module 110 in the first state cuts off power supply to the inertia measurement sensing assembly 140 and the first Lora communication unit 170 through the interface, so that the inertia measurement sensing assembly 140 and the first Lora communication unit 170 enter a sleep state.

Preferably, the first acceleration sensing assembly 120 is provided with a threshold value. In the event that the collected data exceeds the threshold, the first acceleration sensing component 120 generates a wake-up signal and sends a "wake-up signal" to the processing module 110 via the interface. The processing module 110 switches from the first state to the second state in response to receipt of the "wake-up signal". Preferably, the wake-up signal generated by the first acceleration sensing component 120 may be an interrupt signal. The processing module 110 entering the second state turns on the power supply of the inertial measurement sensing component 140 through the interface, so that the inertial measurement sensing component 140 can perform the acquisition of the trajectory data. Preferably, the trajectory data acquired by the inertial measurement sensor assembly 140 is processed by the processing module 110 and then sent to the computing terminal 200 through the first Lora communication unit 170 for computational analysis. Preferably, the processing module 110 in the second state turns on the power supply of the first Lora communication unit 170 through the interface when it is necessary to send the trajectory data collected by the inertia measurement sensing assembly 140 to the computing terminal 200, so that the sensing terminal 100 can perform Lora communication with the computing terminal 200 to transmit the trajectory data collected by the sensing terminal 100. Preferably, when the sensing terminal 100 does not need to transmit data to the computing terminal 200, the processing module 110 cuts off power supply to the first Lora communication unit 170 through the interface, so that power consumption of the system is reduced, and power consumption waste caused by the electrified operation of the first Lora communication unit 170 when data transmission is not needed is avoided. Preferably, the data collected by the first acceleration sensing assembly 120 is only used as a trigger signal for controlling the operating state of the processing module 110, and is not used as a basis for calculation and analysis by the computing terminal 200, and is not required to be transmitted. Preferably, when the data collected by the first acceleration sensing component 120 is lower than the preset threshold, the first acceleration sensing component 120 generates a sleep signal and sends the "sleep signal" to the processing module 110 through the interface. The processing module 110 shuts down power to the inertial measurement sensing component 140 and the first Lora communication unit 170 via the interface in response to the receipt of the "sleep signal". Preferably, the processing module 110 enters the first state of lower power consumption from the second state of higher power consumption in response to the receipt of the sleep signal. Preferably, the first acceleration sensing assembly 120 remains operational regardless of whether the processing module 110 is in the first state or the second state. The first acceleration sensing component 120 generates a wake-up signal or a sleep signal by monitoring the relationship between the collected data and the threshold value, so as to control the working state of the processing module 110, so that the power consumption of the marine disaster monitoring and early warning system of the embodiment can be reduced under the condition of normal operation.

Preferably, the components of the cloud server 300, the computing terminal 200, the first Lora communication unit 170, the first acceleration sensing component 120, the processing module 110, and the like, and the components connected thereto in this embodiment are the same as those in

embodiments

1, 2 and 3, and repeated details are not repeated. In practical use, the sensing terminal 100 of the general object motion analysis system provided by the invention can collect various data on one sensing terminal 100 by integrating various sensing components, so that the system can analyze object motions such as vibration, track, posture and the like. In this embodiment, the general object motion analysis system based on the intelligent motion sensing terminal provided by the invention can be a geological disaster monitoring and early warning system. In the field of geological disaster monitoring and early warning, the general object motion analysis system of the invention utilizes the sensing terminal 100 to collect the track data and the vibration data of rocks or soil, calculates and analyzes the risk data of the vibration amplitude, the sliding amplitude and the like of the rocks or soil through the computing terminal 200, and uploads the technical analysis result to the cloud server 300 to realize the monitoring and early warning of geological disasters such as debris flow, collapse, landslide and the like, thereby realizing the digital upgrading of disaster monitoring.

The geological disaster monitoring and early warning system provided by the embodiment at least comprises a sensing terminal 100, a computing terminal 200 and a cloud server 300. The sensing terminal 100 is provided with at least a first acceleration sensing assembly 120 and an inertial measurement sensing assembly 140. According to the traditional geological disaster monitoring scheme, a stay wire sensor is inserted into a detected rock or soil, a proper position stretching sensor is selected, data collected by the sensor is subjected to signal conditioning, calculation analysis is carried out, and the data are uploaded to a cloud platform. The geological disaster monitoring and early warning system provided by the embodiment can directly measure the rock or soil sliding data of a single point through the sensing terminal 100, then the sensing terminal 100 sends the data to the computing terminal 200 for analysis and calculation through a wired mode and a wireless mode, and the computing terminal 200 uploads a calculation and analysis result to the cloud server 300 to realize monitoring and early warning.

Preferably, the sensing terminal 100 can include a processing module 110, a first acceleration sensing assembly 120, an inertial measurement sensing assembly 140, and a tilt sensing assembly 150. Preferably, the first acceleration sensing assembly 120 is capable of accurately detecting vibration data having a frequency of 10KHz or less. The vibration frequency of each type of geological disaster can fall into the detection range of the first acceleration sensing component 120, and therefore, the sensing terminal 100 of the geological disaster monitoring and early warning system provided by the embodiment is the second acceleration sensing component 160 with the detection frequency greater than 10 KHz.

Preferably, the first acceleration sensing assembly 120, the inertial measurement sensing assembly 140, and the tilt sensing assembly 150 are each connected to the processing module 110 via an interface. The processing module 110 can control the powering of the first acceleration sensing assembly 120, the inertial measurement sensing assembly 140, and the tilt sensing assembly 150 through the interface. The first acceleration sensing assembly 120, the inertial measurement sensing assembly 140, and the tilt sensing assembly 150 can transmit the collected data to the processing module 110 via the interface. Preferably, the interface for data transmission is an interface supporting a communication protocol. Preferably, the interface controlling the power supply may be a general I/O port. The processing module 110 has at least a first state and a second state different from the first state. The first acceleration sensing assembly 120 can control the activation or deactivation of the inertial measurement sensing assembly 140 and the tilt sensing assembly 150 by controlling the switching of the first state and the second state of the processing module 110. Preferably, when the sensing terminal 100 adopted by the geological disaster monitoring and early warning system provided by this embodiment is the wireless sensing terminal 102, the first acceleration sensing component 120 can indirectly control the activation or sleep of the first Lora communication unit 170 by controlling the switching between the first state and the second state of the processing module 110.

Preferably, the first state of the processing module 110 is a sleep state, and the second state is an operating state. Preferably, the inertial measurement sensing assembly 140 and the tilt angle sensing assembly 150 may share a power control interface. Preferably, in actual deployment, the initial state of the sensing terminal 100 is that the processing module 110 is in the first state, the power supply of the inertial measurement sensing component 140 and the tilt angle sensing component 150 is cut off to make them sleep, and the first acceleration sensing component 120 is in the normal working state to collect the vibration data of the object motion in real time.

Preferably, when the vibration data collected by the first acceleration sensing assembly 120 is lower than a preset threshold, the first acceleration sensing assembly 120 keeps collecting the vibration data of the object motion in real time without performing other operations, and each assembly of the sensing terminal 100 keeps an initial state. When the vibration data collected by the first acceleration sensing component 120 changes from being lower than the preset threshold to being higher than the preset threshold, the first acceleration sensing component 120 generates a wake-up interrupt signal and sends the "wake-up interrupt signal" to the processing module 110 through the interface. The processing module 110 switches from the first state to the second state in response to receipt of the wake-up interrupt signal. Preferably, the processing module 110 entering the second state turns on the power supply of the inertial measurement sensing component 140 and the tilt angle sensing component 150 through the power supply control interface shared by the inertial measurement sensing component 140 and the tilt angle sensing component 150, so that the inertial measurement sensing component 140 can acquire the trajectory data of the movement of the object, and the tilt angle sensing component 150 can acquire the attitude data of the movement of the object. Preferably, the processing module 110 enters the second state and receives data collected by the first acceleration sensing assembly 120, the inertial measurement sensing assembly 140, and the tilt sensing assembly 150. Preferably, the processing module 110 in the second state fuses data collected by each sensing component and transmits the fused data to the computing terminal 200 for computational analysis. Preferably, the geological disaster monitoring and early warning system has higher requirements on real-time performance. The sensing terminal 100 of the present embodiment is preferably wired to transmit data to the computing terminal 200, and uses the high-speed communication port 221 for data transmission. In a use environment (such as a cliff) where the wiring operation is inconvenient, the geological disaster monitoring and early warning system used in the embodiment adopts the wireless sensing terminal 102 to collect data. Preferably, the wireless sensing terminal 102 performs wireless communication using the configured first Lora communication unit 170. Preferably, the first Lora communication unit 170 is connected with the processing module 110 through an interface. The processing module 110 can transmit data to the first Lora communication unit 170 through an interface. The processing module 110 may also control the power supply of the first Lora communication unit 170 through an interface. The first acceleration sensing assembly 120 can indirectly control the activation or the sleep of the first Lora communication unit 170 by controlling the switching of the first state and the second state of the processing module 110. Preferably, the processing module 110 cuts off power supply to the first Lora communication unit 170 through the interface to make it sleep when in the first state. When the processing module 110 is in the second state, the processing module 110 only turns on the power supply of the first Lora communication unit 170 to perform data transmission when the data collected by the sensing components needs to be transmitted to the computing terminal 200 after being fused. Preferably, when the sensing terminal 100 does not need to transmit data to the computing terminal 200, the processing module 110 cuts off power supply to the first Lora communication unit 170 through the interface, so that power consumption of the system is reduced, and power consumption waste caused by the electrified operation of the first Lora communication unit 170 when data transmission is not needed is avoided. When the vibration data collected by the first acceleration sensing component 120 changes from being higher than the preset threshold to being lower than the preset threshold, the first acceleration sensing component 120 generates a sleep interrupt signal and sends the "sleep interrupt signal" to the processing module 110 through the interface. Preferably, the processing module 110 enters the first state of lower power consumption from the second state of higher power consumption in response to the receipt of the sleep signal. The processing module 110 turns off power to the inertial measurement sensing component 140 and the tilt angle sensing component 150 via the interface into a sleep state in response to the receipt of the sleep signal. The first acceleration sensing component 120 generates a wake-up signal or a sleep signal by monitoring the relationship between the collected data and the threshold value, so as to control the working state of the processing module 110, so that the power consumption of the geological disaster monitoring and early warning system of the embodiment can be reduced under the condition of normal operation.

Preferably, the sensing terminal 100 of the present embodiment arranges the first acceleration sensing component 120, the inertia measurement sensing component 140 and the tilt angle sensing component 150 on the same board body in a manner that they are axially flush with each other such that the collected data are aligned, so that the processing module 110 can process the data collected by the first acceleration sensing component 120, the inertia measurement sensing component 140 and the tilt angle sensing component 150. Specifically, referring to fig. 18, the first acceleration sensing assembly 120, the inertial measurement sensing assembly 140, and the tilt sensing assembly 150 are disposed in axial alignment on the same plate. Preferably, after the first acceleration sensing assembly 120, the inertial measurement sensing assembly 140 and the tilt angle sensing assembly 150 are disposed on the same plate body in an axis alignment manner, at least one reference parameter of the first acceleration sensing assembly 120, the inertial measurement sensing assembly 140 and the tilt angle sensing assembly 150 is the same when data acquisition is performed, so that the processing module 110 and the computing terminal 200 of the terminal 100 perform fusion processing on data from different sensing assemblies. Preferably, the core components of the first acceleration sensing assembly 120, the inertial measurement sensing assembly 140, and the tilt sensing assembly 150 all include accelerometers. The sensing terminal 100 of this embodiment may set a plurality of sensing components using accelerometers as core devices on a board body of the same circuit structure in an axis alignment manner, so that at least one parameter (e.g., position height, relative coordinate, etc.) of the sensing components is the same, and thus the number of parameters that the processing module 110 of the sensing terminal 100 and the computing terminal 200 need to process when fusing data collected by the sensing components can be reduced, fast processing is achieved, and time spent by the geological disaster monitoring and early warning system of this embodiment when analyzing object motion is indirectly reduced. Preferably, the first acceleration sensing assembly 120, the inertial measurement sensing assembly 140 and the tilt angle sensing assembly 150 are disposed on the plate body at a location away from the surrounding mechanical mounting holes, thereby avoiding external stresses from being transmitted to the sensors. The sensing terminal 100 of the embodiment places each sensing component on the circuit board in the middle, so that the inaccuracy of the data acquisition result of the sensing component caused by the fact that the stress generated by the circuit board is transferred to the sensing component placed on the circuit board due to the fact that the sensing terminal 100 is packaged is avoided.

Preferably, the components and their connected components of the cloud server 300, the computing terminal 200, the first Lora communication unit 170, the first acceleration sensing component 120, the inertia measurement sensing component 140, the tilt sensing component 150, and the processing module 110 used in this embodiment are the same as those in

embodiments

1, 2, 3 and 4, and repeated description is omitted. In this embodiment, the general object motion analysis system based on the intelligent motion sensing terminal can be a power transmission line engineering safety monitoring and early warning system. In the field of safety monitoring and early warning of power transmission line engineering, the general object motion analysis system can utilize the sensing terminal 100 to acquire vibration data, attitude data and trajectory data, calculate and analyze the inclination of the power iron tower and the power line elliptical waving through the computing terminal 200, detect the dangerous conditions of the power iron tower and the power line waving, and upload the calculation and analysis results to the cloud server 300 through the computing terminal 200 to process the corresponding dangerous conditions, so that the digital upgrading of the safety monitoring of the power transmission line engineering is realized.

In the field of safety monitoring and early warning of power transmission line engineering, the traditional technical scheme uses an acceleration sensor to measure displacement data, but the acceleration sensor is difficult to measure the movement track in space, so that the measurement error is large, the track is measured by using a video concentric circle monitoring method, the power consumption of equipment is high, and the construction and installation are inconvenient. The power transmission line engineering safety monitoring and early warning system provided by the embodiment analyzes conditions such as power line galloping track, power tower inclination and the like based on the sensing terminal 100 capable of simultaneously collecting vibration data, attitude data and track data, and uploads an analysis result to the cloud server 300 to realize safety monitoring and early warning.

The power transmission line engineering safety monitoring and early warning system provided by the embodiment comprises a sensing terminal 100, a computing terminal 200 and a cloud server 300. The sensing terminal 100 can be configured with sensing components including a first acceleration sensing component 120, a second acceleration sensing component 160, and/or an inertial measurement sensing component 140 and/or a tilt sensing component 150.

Preferably, the sensing terminal 100 can include one or a combination of several sensing components among the processing module 110, the first acceleration sensing component 120 and the second acceleration sensing component 160, the inertial measurement sensing component 140 and the tilt sensing component 150. The first acceleration sensing assembly 120, the second acceleration sensing assembly 160, and/or the inertial measurement sensing assembly 140 and/or the tilt sensing assembly 150 are each interfaced with the processing module 110. The second acceleration sensing assembly 160 and/or the inertial measurement sensing assembly 140 and/or the tilt sensing assembly 150 can be capable of data acquisition directly or indirectly in response to instructions generated by the first acceleration sensing assembly 120 based on changes in the acquired data.

Preferably, the processing module 110 has at least a first state and a second state different from the first state. The first acceleration sensing assembly 120 can control the activation or deactivation of the second acceleration sensing assembly 160 and/or the inertial measurement sensing assembly 140 and/or the tilt angle sensing assembly 150 by controlling the switching of the first state and the second state of the processing module 110. The first state of the processing module 110 is a sleep state, and the second state is an operating state.

Preferably, in actual deployment, in an initial state, the processing module 110 is in a first state; the first acceleration sensing assembly 120 is in a normal power supply working state; the second acceleration sensing assembly 160 and/or the inertial measurement sensing assembly 140 and/or the tilt sensing assembly 150 are in a powered off sleep state.

When the data collected by the first acceleration sensing component 120 exceeds the preset threshold, the first acceleration sensing component 120 generates an interrupt signal and sends the "interrupt signal" to the processing module 110 through the interface. The processing module 110 switches from the first state to the second state in response to receipt of the interrupt signal. The processing module 110 entering the second state turns on the power supply of the second acceleration sensing assembly 160 and/or the inertial measurement sensing assembly 140 and/or the tilt angle sensing assembly 150 through the interface according to the use requirement, so that the second acceleration sensing assembly 160 and/or the inertial measurement sensing assembly 140 and/or the tilt angle sensing assembly 150 perform data acquisition, and the processing module 110 transmits the data acquired by each sensing assembly to the computing terminal 200 for computation and analysis.

Preferably, when monitoring and early warning the power line waving trajectory, the sensing terminal 100 of the present embodiment may be integrated with the first acceleration sensing element 120, the second acceleration sensing element 160 and the inertia measurement sensing element 140. Preferably, the second acceleration sensing assembly 160 is capable of collecting vibration data at a higher frequency than the first acceleration sensing assembly 120. The first acceleration sensing assembly 120 is provided with a first threshold and is above a second threshold. When the threshold acquired by the first acceleration sensing component 120 is lower than the first threshold, the first acceleration sensing component 120 does not generate an interrupt signal to switch the first state of the processing module 110 to the second state. The first acceleration sensing assembly 120 keeps the data acquisition from other operations. When the threshold value acquired by the first acceleration sensing assembly 120 is higher than the first threshold value and lower than the second threshold value, the first acceleration sensing assembly 120 keeps acquiring data and generates an interrupt signal at the same time, so that the processing module 110 switches from the first state to the second state in response to "receiving of the interrupt signal", at this time, the first acceleration sensing assembly 120 can accurately acquire vibration data, and the processing module 110 only needs to turn on the power supply of the inertia measurement sensing assembly 140, so that the inertia measurement sensing assembly 140 acquires track data. The processing module 110 processes the data collected by the first acceleration sensing component 120 and the inertia measurement sensing component 140 and then transmits the processed data to the computing terminal 200 for computation and analysis, and at this time, the processing module 110 does not need to start the second acceleration sensing component 160. When the threshold value acquired by the first acceleration sensing assembly 120 is higher than the second threshold value, the first acceleration sensing assembly 120 cannot accurately acquire data, and the processing module 110 needs to start the second acceleration sensing assembly 160 to acquire data while starting the inertia measurement sensing assembly 140 to acquire trajectory data.

Preferably, the sensing terminal 100 of the present embodiment arranges one or more sensing assemblies of the first acceleration sensing assembly 120 and the second acceleration sensing assembly 160, the inertia measurement sensing assembly 140 and the tilt angle sensing assembly 150 on the same plate body in a manner that they are axially flush with each other so that the collected data are aligned, so that the processing module 110 can process the data collected by one or more sensing assemblies of the first acceleration sensing assembly 120 and the second acceleration sensing assembly 160, the inertia measurement sensing assembly 140 and the tilt angle sensing assembly 150. Specifically, the first acceleration sensing assembly 120 and the second acceleration sensing assembly 160, and one or more of the inertial measurement sensing assembly 140 and the tilt angle sensing assembly 150 are disposed on the same plate in axial alignment. Preferably, after the first acceleration sensing assembly 120 and the second acceleration sensing assembly 160, and one or more of the inertia measurement sensing assembly 140 and the tilt angle sensing assembly 150 are disposed on the same plate body in an axis alignment manner, at least one reference parameter is the same when data acquisition is performed on the first acceleration sensing assembly 120 and the second acceleration sensing assembly 160, and the one or more of the inertia measurement sensing assembly 140 and the tilt angle sensing assembly 150, so that the processing module 110 of the terminal 100 and the computing terminal 200 can perform fusion processing on data from different sensing assemblies. Preferably, the core components of the first acceleration sensing assembly 120, the second acceleration sensing assembly 160, the inertial measurement sensing assembly 140, and the tilt sensing assembly 150 all include accelerometers. The sensing terminal 100 of this embodiment may set a plurality of sensing components taking accelerometers as core devices on a board body of the same circuit structure in an axis alignment manner, so that at least one parameter (for example, position height, relative coordinate, and the like) of the sensing components is the same, and thus, by reducing the number of parameters that need to be processed when the processing module 110 of the sensing terminal 100 and the computing terminal 200 perform fusion processing on data acquired by the sensing components, rapid processing is implemented, and time consumed when the power transmission line engineering safety monitoring and early warning system of this embodiment performs object motion analysis is reduced. Preferably, each sensing component in the sensing terminal 100 is disposed on the circuit board body at a position far away from the mechanical mounting hole, so as to avoid that external stress is transmitted to the sensor, which results in inaccurate data acquisition results of the sensing component.
