Description

Pile-type sensor device system and its control method { PILE-TYPE SENSOR DEVICE SYSTEM AND CONROLLING METHOD USING IT }

The present invention relates to a pile-type sensor device system and its control method. More specifically, it relates to a pile-type sensor device system and a control method for controlling a plurality of sensor devices installed in a facility to diagnose facility health.

Korea has a small land area and has more mountains than plains. Due to the climatic characteristics of four clearly distinct seasons, high temperature and humidity and heavy rain fall in summer, causing natural disasters such as floods, landslides, and typhoons, and low temperature and dry climate in winter. As a result, cold waves and heavy snow are occurring.

Due to the characteristics of the four-season climate, natural disasters such as floods, landslides, and typhoons occur in summer, causing collapse of facilities such as slopes, and roads are blocked or traffic accidents involving passing vehicles occur due to soil lost from slopes. Accidents involving apartments and houses being buried frequently occur.

In addition, during thawing periods such as spring, facilities such as underground buried pipes, dams, and buildings undergo a process of freezing and thawing, which accelerates aging or cracks earlier than their actual designed lifespan, and in severe cases, even leads to collapse accidents.

In addition, due to external shocks such as earthquakes, which have frequently occurred recently, facilities such as slopes, underground buried pipes, dams, and buildings are often destroyed or internal structural displacement occurs, putting them in dangerous situations.

In addition, when a facility such as a slope, an underground buried pipe, a dam, or a building is destroyed or structural displacement occurs inside, waves (elastic waves, sound waves, ultrasonic waves, etc.) are generated due to the structural defect. Waves generated due to structural displacement inside facilities such as buried pipes, dams, and buildings are difficult to measure due to their weak signal strength. When the measured waves are transmitted to the outside for signal analysis, the transmission process is difficult due to the characteristics of weak wave signals. The reality is that signal analysis is also difficult due to signal loss.

Conventionally, a number of acoustic emission sensors (AE Sensors) are installed on structural defect diagnosis objects such as facilities, and defects in the inspection object are measured by analyzing elastic waves generated when the structural defect diagnosis object is deformed, cracked, leaked, or destroyed. Non-destructive testing methods are used, but if a defect occurs in the acoustic emission sensor (AE Sensor) itself that measures elastic waves, the elastic wave transmitted by the acoustic emission sensor (AE Sensor) contains elastic wave components caused by the defect in the acoustic emission sensor (AE Sensor) itself. There is a problem that incorrect analysis occurs when analyzing deformation, cracking, leakage, or destruction of a structural defect diagnosis object. In consideration of the above, the following describes a sensor device that is inserted and installed at a certain depth inside a facility such as a slope, an underground buried pipe, a dam, or a building to sense structural defects inside the facility, and thereby to monitor the soundness (or safety) of the facility. Describes how to sense.

Referring to FIG. 1, a pile-type sensor device for diagnosing facility health (hereinafter referred to as sensor device 10) can be inserted and installed inside a facility to obtain sensing information for diagnosing facility health. As an example, the sensor device 10 can be inserted and installed inside a facility such as a slope, an underground buried pipe, a dam, or a building at a certain depth to evaluate the soundness of the facility by detecting change information that occurs due to structural displacement inside the facility. there is. Referring to FIG. 1 , the sensor device 10 may include a steel pile unit 100, a sensing unit 200, and an amplifying unit 300. Additionally, the sensor device 10 may further include an automatic measurement unit 400. Additionally, the automatic measurement unit 400 may be included in a pile-type sensor device system for diagnosing facility health that includes at least one sensor device 10. As an example, the automatic measurement unit 400 may be located outside the sensor device 10 and may perform facility health evaluation based on sensing information obtained from the sensor device 10, which will be described later.

As an example, the sensor device 10 of FIG. 1 may be inserted into a facility at a preset depth and sense change information that occurs based on structural displacement inside the facility. Here, based on the change information, the sensor device 10 may generate an electrical wave signal, amplify the electrical wave signal, and provide it to the outside. As an example, Figure 2 is a diagram showing a method of applying a pile-type sensor for facility diagnosis according to an embodiment of the present invention. Referring to FIG. 2, the sensor device 10 may be inserted and installed in a structure where internal structural displacement may occur, such as a slope, an underground buried pipe, a dam, or a building.

It can be provided externally. As another example, Figure 2(C) shows that the sensor device 10 is inserted into a building or dam, which detects change information that occurs due to displacement of the internal structure of the building or dam, and generates an electrical waveform signal based on this. It can be provided externally.

As a specific example, Figure 3 is a diagram showing the configuration included in a pile-type sensor for facility diagnosis according to an embodiment of the present invention. Referring to FIG. 3, the sensor device 10 is inserted inside the facility, and is installed inside the steel pile portion 100, where sensing information generated according to structural displacement within the facility is collected, A sensing unit that detects change information that occurs due to displacement of the facility's internal structure and is collected and transmitted through the steel pile unit (100), generates an electrical waveform signal corresponding to the detected change information, and provides it to the amplification unit (300). It may include (200) and an amplifying unit 300 that is installed inside the steel pile unit 100 and amplifies the electrical waveform signal provided by the sensing unit 200 and provides it to the outside. Additionally, the sensor device 10 may include an automatic measurement unit 400 that collects sensed change information and automatically performs measurement. As an example, the automatic measurement unit 400 may be included in the sensor device 10 or may be included in a sensor device system consisting of at least one sensor device 10.

As an example, a structure that improves change information sensing efficiency may be formed in the steel pile portion 100 of the sensor device 10. The sensing unit 200 and the amplifying unit 300 can be independently fixedly installed inside the steel pile unit 100 to prevent them from being pulled out of the steel pile unit 100. The steel pile part 100 has an internal space, is formed to a certain length, is inserted into the facility, and can collect information on changes that occur due to displacement of the facility's internal structure. Here, the internal space of the steel pile unit 100 may include a sensing unit 200 and an amplifying unit 300. As an example, collection wings 150, which are structures that improve change information collection efficiency, are formed in the steel-type pile unit 100, so that change information collection efficiency can be improved, and thus the sensing information detection efficiency of the sensing unit 200. This can be improved. In addition, the steel-type pile part 100 is made by drilling a hole in a facility and then inserting the steel-type pile part 100 into the drilled hole to insert the steel-type pile part 100 into the facility or by piling without a drilled hole. It can be directly struck and inserted into the facility by equipment. When inserted inside the facility, the steel pile unit 100 functions as a protective case that protects the sensing unit 200 and the amplifying unit 300 installed inside from the external environment, and at the same time, damage occurs due to displacement of the internal structure of the facility. Change information can be collected. That is, change information that occurs due to displacement of the internal structure of the facility may be transmitted to the sensing unit 200 through the steel pile unit 100. The steel pile unit 100 can collect information on changes occurring inside the facility according to displacement of the facility's internal structure. As an example, referring to Figure 5, the steel-type pile portion 100 is in contact with the sensing portion 200, and is coupled to the pile body portion 120 to form the tip of the steel-type pile portion 100 ( 110) may be included. One side of the pile body 120 may be coupled to the pile tip 110, and the other side may be coupled to the finishing cover 130. Here, a hollow 121 is formed inside the pile body 120 so that the sensing unit 200 and the amplifying unit 300 can be installed, so that the pile body 120 having a cylindrical shape of a certain length can be configured. there is. In addition, the finishing cover 130, which is detachably coupled to the entrance of the pile body 120 to prevent foreign substances from entering the pile body 120, and the second signal transmission line 350 of the amplification unit 300 are connected to the outside. A drawing groove 140 formed on one side of the side of the pile body 120 where the finishing cover 130 is coupled so that it can be drawn out, and the efficiency of collecting information on changes occurring due to displacement of the internal structure of the facility is improved. It may include at least one collection wing 150 formed on the surface of the pile body 120. As an example, referring to FIG. 5 , the pile tip 110 may be in contact with the sensing unit 200 and may be coupled to the pile body 120 to form the tip of the steel-type pile portion 100. The pile tip 110 is formed in a cone shape so that the steel pile portion 100 can be easily inserted into the facility, and the tip portion 111 and pile body portion 120 form the tip of the steel pile portion 100. ) may include a flat sensor contact surface 113 formed at the end of the pile coupling portion 112 to contact the pile coupling portion 112 and the sensing unit 200. As an example, the peak portion 111 corresponds to the tip of the steel pile portion 100 and may be formed in a cone shape so that the steel pile portion 100 can be easily inserted into the facility. In addition, the pile coupling portion 112 is a portion coupled to the pile body portion 120 and is formed with a thread for coupling. The sensor contact surface 113 is in contact with the sensing unit 200 and may have a flat shape, and may be formed at the end of the pile coupling portion 112. That is, as shown in FIG. 5, a flat flat surface is formed at the end of the pile coupling part 112 so that the sensing unit 200 contacts it, and the detection sensor of the sensing unit 200 through the flat sensor contact surface 113. Information on changes occurring inside the facility can be delivered to (220). In addition, for ease of coupling with the pile body 120, the pile tip 110 has a friction surface 114 having a certain roughness around the side of the pile tip 110 between the tip 111 and the pile coupling portion 112. ) and at least two flat surfaces 115 formed on the friction surface 114.

In addition, when coupling the pile tip 110 to the pile body 120, it can be coupled by turning it manually or by turning it using equipment (a wrench, etc.). As an example, a cone-shaped peak 111 may be formed at the part where hands or equipment come into contact for coupling. The cone-shaped tip 111 is inconvenient for hands or equipment to contact due to its shape, and therefore, it may be inconvenient to couple the file tip 110 to the pile body 120. Therefore, when coupling the pile tip 110 to the pile body 120, for ease of coupling, a friction surface having a certain roughness is formed around the side of the pile tip 110 between the tip 111 and the pile coupling portion 112. At least two or more flat surfaces 115 may be formed on (114) and the friction surface (114). Additionally, referring to Figure 5, one side of the pile body portion 120 may be coupled to the pile tip portion 110 and the other side may be coupled to the finishing cover 130. In addition, the pile body 120 may have a cylindrical shape of a certain length and a hollow 121 that allows the sensing unit 200 and the amplifying unit 300 to be installed, as described above. As an example, the pile body portion 120 may be composed of several cylinders combined, or may be composed of a single cylinder, and is not limited to a specific embodiment.

In addition, as an example, referring to Figure 5, the finishing cover 130 is configured to be detachably coupled (e.g. screw coupled method) to the entrance of the pile body 120 to prevent foreign substances from entering the pile body 120. It can be.

As an example, the electrical waveform signal amplified by the preamplifier board 320 of the amplification unit 300 is transmitted to the outside through the second signal transmission line 350 of the amplification unit 300. External transmission of the amplified electrical waveform signal For this, the second signal transmission line 350 must be pulled out to the outside of the steel pile part 100, and the structure for this may be the lead-out groove 140. When inserting the steel pile unit 100 into the facility, the finishing cover 130 may be struck to allow the steel pile unit 100 to be inserted into the facility. Here, when the withdrawal groove 140 is formed in the finishing cover 130, the second signal transmission line 350 may be hit and damaged when the finishing cover 130 for inserting the steel-type pile part 100 is hit. In order to prevent the above-mentioned problem, the withdrawal groove 140 may be formed on one side of the side of the pile body 120, where the finishing cover 130 is coupled.

Figure 6 is a diagram showing the configuration included in the sensing unit of the pile-type sensor for facility diagnosis according to an embodiment of the present invention. As an example, the sensing unit 200 may include a first sensing unit 210, a second sensing unit 220, and a third sensing unit 230. Additionally, the sensing unit may further include other sensing units and may not be limited to a specific number. As an example, the first sensing unit 210 may be a sensing unit that senses elastic waves. Specifically, elastic waves may be generated depending on structural displacement inside the facility. Here, it is possible to determine whether there is a structural displacement inside the facility through the generated elastic waves, and the first sensing unit 210 can detect the elastic waves. As an example, referring to FIG. 6(a), the first sensing unit 210 may include a sensor housing 211 installed inside the mounting cap 213 with a detection sensor 212 inserted therein. there is. In addition, it is installed inside the sensor housing 211 to detect elastic waves transmitted inside the facility through the sensor contact surface 113, and the sensing surface is a steel pile part 100 to generate an electrical wave signal corresponding to the detected elastic wave. It may include a detection sensor 212 that contacts the flat sensor contact surface 113 formed on the file tip 110. As an example, the sensor housing 211 and the elastic member 214 are located on the inside so that the sensing surface of the detection sensor 212 is in contact with the flat sensor contact surface 113 formed on the file tip 110, and the sensor contact surface 113 It may include a mounting cap 213 coupled to. The sensing surface of the detection sensor 212 may be maintained in surface contact with the flat sensor contact surface 113 formed on the pile tip 110. As an example, the electrical waveform signal generated by the hollow elastic member 214 and the detection sensor 212 installed inside the mounting cap 213 to pressurize the sensor housing 211 is transmitted to the pre-amplifier of the amplification unit 300. It may include a first signal transmission line 215 that is transmitted to the board 320. As an example, referring to FIG. 6(a), the sensor housing 211 may be configured to have the detection sensor 212 inserted and installed inside the mounting cap 213. As the detection sensor 212 is inserted inside, one side of the sensor housing 211 may be opened so that the detection surface of the detection sensor 212 inserted inside may be exposed to the outside. For example, the elastic wave detected by the detection sensor 212 may be an elastic wave in the 1 kHz to 1 MHz band.

In addition, the mounting cap 213 has the sensor housing 211 and the elastic member 214 positioned on the inside so that the sensing surface of the detection sensor 212 is in contact with the flat sensor contact surface 113 formed on the pile tip 110. It may be configured to be coupled to the sensor contact surface 113. In addition, the elastic member 214 is a mounting cap to press the sensor housing 211 with elastic force so that the sensing surface of the detection sensor 212 can be maintained in contact with the flat sensor contact surface 113 formed on the pile tip 110. (213) It may be configured to be installed on the inside. For example, the elastic member 213 may be a member with elastic force, such as a spring, hollow rubber, or cork. The reason for forming a hollow in the elastic member 213 is to allow the first signal transmission line 215, which will be described later, connected to the detection sensor 212 to penetrate the elastic member. The first signal transmission line 215 may be configured to transmit the electrical waveform signal generated by the detection sensor 212 to the pre-amplifier board 320 of the amplifier 300. One side of the first signal transmission line 215 is connected to the detection sensor 212, and the other side is connected to the preamplifier board 320 of the amplification unit 300, so that the electrical waveform signal generated by the detection sensor 212 is transmitted to the amplification unit 300. It can be transmitted to the preamplifier board 320 of 300. The amplification unit 300 may be installed inside the steel pile unit 100 described above and may be configured to amplify the electrical waveform signal provided by the sensing unit 200 and provide the signal to the outside. As an example, referring to FIG. 7, the amplification unit 300 is installed inside the preamplifier board housing 310, where the preamplifier board 320 is installed, and the sensing unit 200. ) The preamplifier board 320 and the preamplifier board housing 310, which are designed with an amplification circuit that amplifies the electrical waveform signal transmitted from ), are positioned at a certain position inside the pile body portion 120 of the steel pile portion 100. , one side is coupled to the preamplifier board housing 310, and the other side is coupled to the flat sensor contact surface 111 formed on the pile tip 110 of the steel-type pile portion 100. It includes at least one fixed support bar 330. can do. Additionally, it may include a second signal transmission line 340 that allows the electrical waveform signal amplified through the preamplifier board 320 to be transmitted to the outside. Referring to FIG. 7, the preamplifier board housing 310 may be a type of enclosure that allows the preamplifier board 320 to be installed inside. That is, the preamplifier board housing 310 can protect the preamplifier board 320 installed inside from the external environment. The preamplifier board 320 is installed inside the preamplifier board housing 310, which is an enclosure, and may have a boat-type configuration in which an amplification circuit is designed to amplify the electrical waveform signal transmitted from the sensing unit 200. In addition, the slide groove 330 is an insertion guide of a certain length formed in the hollow 311 so that the preamplifier board 320 can be inserted into the hollow 311 formed inside the preamplifier board housing 310 in a slide manner. It could be home. The preamplifier board 320, a board type designed with an amplification circuit, may need to be positioned inside the preamplifier board housing 310 in a stable state for stable signal amplification. The preamplifier board 320, which is inserted into the slide groove 330 and is stably positioned inside the preamplifier board housing 310, can stably amplify the electrical waveform signal transmitted from the sensing unit 200. Referring to FIG. 7, the second signal transmission line 340 allows the electrical waveform signal amplified through the preamplifier board 320 to be transmitted to the outside. As an example, the second signal transmission line 340, one side of which is connected to the preamplifier board 320, has a hollow 121 formed inside the pile body 120 and a drawout groove 140 formed in the pile body 120 described above. Through this, the amplified electrical waveform signal can be drawn out to the outside of the file body 120 and transmitted to the outside for signal analysis.

Additionally, as an example, the second sensing unit 220 may sense pressure. Referring to FIG. 6(b), the pressure sensor 222 is inserted inside the second sensing unit 220 and may include a sensor housing 221 installed inside the mounting cap 223. In addition, it is installed inside the sensor housing 221 to detect pressure transmitted from inside the facility, and the sensing surface is on the side of the pile body 120 of the steel pile portion 100 to generate an electrical waveform signal from the sensed pressure. It may include a pressure sensor 222 that is in contact. As an example, the steel pile part 100 may be inserted and installed inside a facility. Here, when structural displacement occurs inside the facility, pressure may be applied to the steel pile portion 100 due to the structural displacement. Specifically, pressure may be applied to both sides of the pile body portion 120. In consideration of the above, the sensing surface of the pressure sensor 222 may be formed on one side of the pile body portion 120. As an example, the second sensing unit 220 is a mounting cap coupled to the sensor contact surface 123 with the sensor housing 221 and the elastic member 224 located on the inside so as to contact one side of the pile body 120. 223) may be included. The pressure sensor 222 measures the pressure generated in the steel pile unit 100 to generate an electrical signal, and a first signal transmission line that transmits the generated electrical waveform signal to the pre-amplifier board 320 of the amplification unit 300. It may include (225). The amplifying unit 300 may be installed inside the steel pile unit 100 described above and may be configured to amplify the electrical waveform signal provided by the sensing unit 200 and provide the signal to the outside, as described above.

Additionally, as an example, the third sensing unit 230 may sense location information of the sensor device 10 by receiving a wireless signal. Additionally, the third sensing unit 230 may sense a wireless signal transmitted from outside the sensor device 10 to measure sensing information or transmit the collected data to the outside. Referring to FIG. 6(c), the third sensing unit 230 may include a wireless transceiving unit 232 that transmits and receives wireless signals and a sensor housing 231 outside the wireless transceiving unit 232. Additionally, the third sensing unit 230 may include a first signal transmission line 235 that allows the electrical waveform signal to be transmitted to the pre-amplifier board 320 of the amplifying unit 300. Additionally, the third sensing unit 230 may include an elastic member 234 that protects the wireless transceiving unit 232 from external shock. The third sensing unit 230 may be configured inside the pile body 120, and, unlike the first sensing unit 210 and the second sensing unit 220, is located on one side of the steel pile unit 100 and There may be no contact. The third sensing unit 230 may be in a form that is not attached to one side of the steel pile unit 100 so as not to be damaged by external impact, and the first sensing unit 210 and the first sensing unit 210 within the pile body unit 120 2 It may be located inside the sensing unit 220. The third sensing unit 230 is configured inside the file body 120 and can exchange wireless signals with an external device through the wireless transmitting and receiving unit 232. As an example, the third sensing unit 230 can acquire a GPS signal or a signal related to location information through the wireless transmitting and receiving unit 232, and can recognize the location of the sensor device 10 through this. For example, the sensor device 10 is inserted and installed inside one side of a facility, so it may have a fixed position. However, the location may change due to changes in the internal structure of the facility, and if the location changes, it may be recognized that there is a problem with the soundness of the facility. That is, location information can be recognized through the third sensing unit 230, and the health of the facility can be evaluated based on this. As another example, the third sensing unit 230 is generated based on measurements of the first sensing unit 210 and the second sensing unit 220 from the amplifying unit 300 through the first signal transmission line 235. An amplified electrical signal can be obtained. That is, the third sensing unit 230 may be connected to the amplifying unit 300 through the first signal transmission line 235 and obtain sensed information. The third sensing unit 230 can transmit the acquired sensing information to the outside through the wireless transmitting and receiving unit 232. As an example, the wireless transceiver 232 may operate on a low power basis. Considering that the wireless transceiver unit 232 is a low-power device, it may maintain a sleep state and then switch to an awake state based on a preset period to obtain sensing information. As another example, the third sensing unit 230 may further include a power unit (not shown) to supply power to the wireless transceiver 232. However, considering that the sensor device 10 is inserted and installed inside a facility, even if the third sensing unit 230 includes a power unit, the wireless transmitting and receiving unit 232 may operate based on low power and may be operated in a specific form. It may not be limited.

Figure 8 is a diagram showing the configuration included in the automatic measurement unit of the pile-type sensor for facility diagnosis according to an embodiment of the present invention. Referring to FIG. 8, the sensor device 10 may include an automatic measurement unit 400. As another example, the automatic measurement unit 400 may be included in a sensor device system including at least one sensor device 10 and may be installed outside the sensor device 10. The automatic measurement unit 400 includes a data collection unit 410 that collects data obtained from the sensor device 10, a data processing unit 420 that acquires data from the data collection unit 410 and performs preprocessing, and preprocessing. It may include an artificial intelligence unit 430 that automatically performs a facility health diagnosis based on the received data, and a transceiver unit 440 that transmits the facility health diagnosis result obtained from the artificial intelligence unit 430 to the outside.

As a specific example, the third sensing unit 230 converts the signal measured by the first sensing unit 210 and the second sensing unit 220 into an electrical signal and then amplifies the signal through the amplifying unit 300 to the amplifying unit ( 300). Here, the third sensing unit 230 may transmit sensing information to the data collection unit 410 of the automatic measurement unit 400 through the wireless transmitting and receiving unit 232 of the third sensing unit. As an example, the sensing information transmitted by the wireless transmitting and receiving unit 232 of the third sensing unit to the data collection unit 410 is elastic wave information measured through the first sensing unit 210 and measured through the second sensing unit 220. It may include pressure information, location information measured through the third sensing unit 230, and wireless signal information. That is, the automatic measurement unit 400 can collect information sensed by the sensing unit 200, and through this, accuracy can be increased compared to the case where facility health diagnostic evaluation is performed using only elastic waves.

The data processing unit 420 may obtain sensing information from the data collection unit 410. Afterwards, the data processing unit 420 may perform preprocessing to apply the sensing information to the artificial intelligence unit 430. The data processing unit 420 can transmit only information exceeding a preset value among the sensing information to the artificial intelligence unit 430. As a specific example, the data processing unit 420 may be set with respective threshold information for elastic wave values, pressure values, and position change values. The data processing unit 420 may determine that values smaller than the threshold among the sensing information acquired through the data collection unit 410 are values that do not affect the facility and exclude them. That is, the data processing unit 420 may perform a preprocessing process to exclude information about minute vibration or minute pressure and extract only information that may affect the evaluation of facility health. Afterwards, the preprocessed sensing information may be transmitted to the artificial intelligence unit 430. As an example, the artificial intelligence unit 430 may be equipped with a facility health evaluation learning model. Here, the facility health evaluation learning model may be a learning model learned based on data related to facility health. As an example, a facility health evaluation learning model may be learned based on the facility characteristics and the above-described sensing information. The artificial intelligence unit 430 may provide preprocessed sensing information obtained through the data processing unit 420 as input to the facility health learning model. The facility health learning model performs inference based on preprocessed sensing information and can derive facility health evaluation information as output according to the inference. Here, the facility health evaluation information can be fed back to the facility health learning model, and through this, the facility health learning model can be updated. Additionally, the automatic measuring unit 400 can transmit facility health evaluation information to an external device through the transmitting and receiving unit 440. As an example, the automatic measurement unit 400 may transmit facility health evaluation information to an external server or user terminal through the transceiver unit 440. As another example, the automatic measurement unit 400 may digitize the facility health evaluation information, and if the quantified value is higher than a threshold value, the automatic measurement unit 400 may transmit the facility health evaluation information to the equipment. That is, if the automatic measurement unit 400 determines that there is a problem with the facility health based on the facility health evaluation information, it can transmit the facility health evaluation information to an external device.

Figure 9 is a diagram showing a method of transmitting information sensed by a pile-type sensor for facility diagnosis according to an embodiment of the present invention. Referring to FIG. 9, a pile-type sensor device system for diagnosing facility health including a sensor device 10 can be considered. For example, the facility may be a slope, a building, a dam, etc., as described above. Here, the size of the facility may be large, and there is a need to derive sensing information through the sensor device 10 in each area inside the facility. In other words, there may be limitations in diagnosing the health of a facility with a single sensor device 10, and in consideration of this, a pile-type sensor device system (hereinafter referred to as a sensor device system) for diagnosing the health of a facility may be considered. As an example, one sensor device system may be set up by a plurality of sensor devices 10 installed in one facility. That is, the sensor device system can be set for each facility, and the sensor device system can manage a plurality of sensor devices 10 installed inside the facility. As an example, the sensor device system may provide identification information to each of the plurality of sensor devices 10 installed inside the facility. The sensor device system can manage each of the plurality of sensor devices 10 based on identification information. Additionally, the sensor device system may obtain information on the sensing unit included in each sensor device 10 based on the identification information. As an example, each of the plurality of sensor devices 10 may include the first sensing unit 210, the second sensing unit 220, and the third sensing unit 230 described above. As another example, each of the plurality of sensor devices 10 may include only some of the above-described first sensing unit 210, second sensing unit 220, and third sensing unit 230. The sensor device system can check the sensing unit information included in each sensor device 10 based on the identification information for each of the plurality of sensor devices 10, and obtain sensing information from each sensor device 10 based on this. can do. As an example, the automatic measurement unit 400 described above may be included in a sensor device system, but may not be limited thereto.

As another example, a plurality of repeaters 910, 920, 930, and 940 may be included inside the facility. Here, each of the plurality of repeaters 910, 920, 930, and 940 may be installed at a preset location in consideration of the size of the facility. Specifically, as described above, sensing information can be transmitted to an external device through the third sensing unit 230 of the sensor device 10, but since the sensor device 10 is a device that operates at low power, there are limitations in transmitting sensing information. may exist. In consideration of the above, a plurality of repeaters 910, 920, 930, and 940 may be installed at preset positions inside the facility. As an example, each of the plurality of repeaters 910, 920, 930, and 940 may acquire sensing information from the sensor device 10 within a preset distance and transmit the acquired sensing information to the automatic measurement unit 400. As an example, each of the plurality of repeaters 910, 920, 930, and 940 may recognize the sensor device 10 it manages by obtaining identification information for each of the plurality of sensor devices 10 from the sensor device system. . The sensor device system can install a plurality of repeaters (910, 920, 930, 940) at preset locations in consideration of the size of the facility, and each of the plurality of repeaters (910, 920, 930, 940) is also based on identification information. Thus, it can be registered in the sensor device system. Through the above-described information, the sensor device system can obtain sensing information from the sensor device 10 and perform facility health evaluation.

Figure 10 is a diagram showing details of the sensor unit of the pile-type sensor for facility diagnosis according to an embodiment of the present invention. As an example, referring to FIG. 10 , the sensing unit 200 may further include a real-time monitoring unit 201 and a precision monitoring unit 202. Here, the real-time monitoring unit 201 can monitor the elastic wave information obtained from the first sensing unit 210 in real time and transmit it to the repeater 900. Specifically, the first sensing unit 210 may sense elastic waves generated according to the displacement of the facility structure. The real-time monitoring unit 201 of the sensing unit 200 can change the generated elastic wave into an electrical signal and transmit it to the amplification unit 300, and the amplification unit 300 transmits the electrical signal for the elastic wave to the repeater 900 in real time. It can be delivered. Here, the facility health evaluation can be performed by elastic waves generated according to structural displacement, and the corresponding values can be monitored in real time to evaluate the facility soundness. Here, as an example, the sensing unit 200 may further include a precision monitoring unit 202. As an example, the precision monitoring unit 202 is connected to all sensing units including the first sensing unit 210, the second sensing unit 220, and the third sensing unit 230 of the sensing unit 200 to collect sensing information. can be obtained. The precision monitoring unit 202 can change the sensed information into an electrical signal and transmit it to the amplification unit 300. As an example, the sensing information transmitted to the amplification unit 300 may be stored in the memory (not shown) of the amplification unit 300. Sensing information stored in the memory of the amplifier 300 may not be transmitted to an external device in real time. As an example, the sensing information stored in the memory of the amplifier 300 may be transmitted at once after receiving a request from the terminal device 1000 or an external device. Specifically, the precision monitoring unit 202 can store all sensing information of the sensing unit 200. Here, the sensor device 10 may be a low-power device, and if all sensed information is transmitted in real time, power consumption may increase. In consideration of the above, the sensing unit 200 transmits the seismic wave information of the first sensing unit 210 through the real-time monitoring unit 201 in real time for facility health evaluation, and all sensing information is delivered only upon request. You can do it. For example, when coupling to a facility occurs based on a facility health evaluation, the terminal device 1000 may request all sensing information from the sensor device 10, and the precision monitoring unit 202 of the sensing unit 200 may All sensing information of the sensing unit 200 can be transmitted. In other words, real-time monitoring and precise monitoring can be performed separately.

Figure 11 is a diagram showing a method for sensing facility defects according to an embodiment of the present invention. Referring to FIG. 11, when coupling occurs in a facility, elastic waves may be generated according to structural displacement of the facility, pressure may be applied, or the position of the sensor device 10 may change. For example, when coupling occurs at a specific point 1110 inside a facility, the specific point 1110 may be sensed through at least one sensor device 10 of the sensor device system. Here, the sensor device 10 may perform sensing at a specific point 1110 where a defect occurs. However, sensing accuracy can be increased by allowing only sensor devices 10 within a preset distance from the specific point 1110 where the defect occurred to perform sensing, so sensor devices 10 within a preset distance from the specific point 1110 where the defect occurred Only (10) can perform sensing. For example, in FIG. 11, the first sensor device 1120 can perform sensing because it is within a preset distance from the specific point 1110 where the defect occurred, and the second device 1130 can detect the specific point 1110 where the defect occurred. Because it is located farther than the preset distance, sensing may not be performed.

As a more specific example, the location of a specific point 1110 where a defect occurs may be determined by elastic waves through the first sensing unit 210. In other words, when structural displacement occurs based on a defect inside a facility, elastic waves can be generated and transmitted. Here, each of the sensor devices 10 of the sensor device system can sense the generated elastic waves. As an example, the sensor device system may determine a specific point 1110 where a defect occurs based on elastic waves sensed from each of the sensor devices 10. The sensor device system can check the elastic wave intensity information sensed from each of the sensor devices 10 and the location information of each of the sensor devices 10. The sensor device system can recognize a specific point 1110 where a defect occurs through elastic wave intensity information and location information of each sensor device 10. When the sensor device system recognizes a specific point 1110 where a defect occurs, it can identify the sensor devices 10 within a preset distance from the specific point 1110 based on the location information of each sensor device 10. Afterwards, the sensor device system may transmit a precise monitoring sensing request to sensor devices 10 within a preset distance from the specific point 1110. The sensor devices 10 may obtain sensing information through all sensing units of the sensing unit 200 and transmit the information to the sensor device system. That is, each of the plurality of sensor devices 10 installed inside the facility can measure elastic waves through the first sensing unit 210 and obtain sensing information from all sensing units through precise monitoring upon request.

Figure 12 is a diagram showing a method of assigning weights to each sensing unit according to an embodiment of the present invention. Referring to FIG. 12, the above-described automatic measurement unit 400 automatically detects sensing information through the first sensing unit 210, second sensing unit 220, and third sensing unit 230 of the sensing unit 200. By acquiring and applying the corresponding sensing information to the artificial intelligence unit 430, facility health evaluation information can be derived, as described above. When the automatic measurement unit 400 provides sensing information to the artificial intelligence unit 430, the weight for each sensing information may be different based on the characteristics of the facility where the sensor device 10 is installed. Specifically, the weight for each sensing information may be different based on the characteristics of the facility where the sensor device 10 is installed or the location where the sensor device 10 is installed within the facility. For example, the weights for each of the first sensing unit 210, the second sensing unit 220, and the third sensing unit 230 may be W1, W2, and W3. Here, each weight may be different depending on facility characteristics. Referring to FIG. 12(A), when the facility is on a slope, the weight of the first sensing unit 210 may be high and the weight of the second sensing unit 220 may be low. For example, on a slope, the measurement accuracy using elastic waves may be high, but since the pressure may not be constant, the weight of the second sensing unit 220 may be low. However, this is only one example and is not limited thereto.

In addition, in the underground buried pipe of FIG. 12(B) or the building dam of FIG. 12(C), the weight of the first sensing unit 210 and the weight of the second sensing unit 220 are similar, and the weight of the third sensing unit 230 ) may have a low weight. For example, in underground buried pipes, buildings, dams, etc., the materials are evenly composed in a certain shape, so the measurement accuracy by elastic waves and the measurement accuracy by pressure can be high, and can have similar weights. On the other hand, since it is unlikely that the position of the sensor device 10 will change in the underground buried pipe of FIG. 12(B) or the building dam of FIG. 12(C), the weight of the third sensing unit 230 may be low. However, this is only one example and is not limited thereto. As described above, the automatic measurement unit 400 can set the weights for each of the first sensing unit 210, the second sensing unit 220, and the third sensing unit 230 differently according to facility characteristics, and artificial intelligence When sensing information is provided to the unit 430 as input, the corresponding weight can be reflected. Through this, the accuracy of facility health evaluation can be increased, but it is not limited to this embodiment. As another example, the weights for each of the first sensing unit 210, the second sensing unit 220, and the third sensing unit 230 may be set differently based on the installation location of the sensor device 10 in the facility. there is. As a specific example, when elastic waves are generated due to structural displacement on the surface of a facility, the elastic waves may be transmitted to the outside, and the pressure may be low, so the first sensing unit ( The weights of 210) and the second sensing unit 220 may be set low. On the other hand, if elastic waves are generated due to structural displacement at the bottom of the facility, the elastic waves may be completely absorbed inside, and the pressure may also be high. Accordingly, in the sensor device 10 installed inside a facility to perform sensing, the weights of the first sensing unit 210 and the second sensing unit 220 may be set high, and are not limited to a specific form. That is, the weights of each of the first sensing unit 210, the second sensing unit 220, and the third sensing unit 230 may be set differently depending on the installation location of the sensor device 10 within the facility.

Figure 13 is a diagram showing a method of performing sensing based on a pile-type sensor type for facility diagnosis according to an embodiment of the present invention. Referring to FIG. 13, the type of sensor device 10 may be set differently. As an example, the sensing unit 200 of the sensor device 10 may include the above-described first sensing unit 210, second sensing unit 220, and third sensing unit 230, but is not limited thereto. It may further include other sensing units. Here, the type of sensor device 10 may be determined by the sensing unit included in the sensor device 10. That is, different types of sensor devices 10 may include different sensing units. As a specific example, referring to FIG. 13, the sensor device 10 installed inside a building as a facility may be a first type sensor device 1311 and 1312, and the sensor device 10 installed outside the building may be a second type sensor. It may be a device 1321, 1322, or 1323. As an example, the first type sensor devices 1311 and 1312 can be installed inside a building to measure elastic waves and pressure according to the displacement of the facility structure, and for this purpose, the above-described first sensing unit 210 and the second sensing unit ( 220) and a third sensing unit 230. On the other hand, the second type sensor devices 1321, 1322, and 1323 may be installed outside the building. For example, one side of the second type sensor devices 1321, 1322, and 1323 may be exposed to the outside and may be affected by the external environment. As a specific example, when it rains or snows, the sensing accuracy of the second type sensor devices 1321, 1322, and 1323 with one side exposed to the outside may decrease. If moisture exists on one exposed side, elastic waves generated by structural displacement of the facility may be measured differently depending on the moisture. As another example, when pressure is generated due to snowfall on one exposed side, the pressure generated due to structural displacement of the facility may be measured differently. In consideration of the above, the second type sensor devices 1321, 1322, and 1323 may further include an environmental information sensing unit (not shown). The environmental information sensing unit can measure temperature, weather, and other surrounding environmental information in the external environment, and can obtain sensing information by reflecting the corresponding sensing information. As another example, the second type sensor devices 1321, 1322, and 1323 may determine a sensing unit to be used based on the surrounding environment sensing unit. The second type sensor devices 1321, 1322, and 1323 may exclude the second sensing unit 220 and obtain sensing information when pressure is generated in the sensor device 10 due to snowfall, but the device is not limited to this. .

That is, the sensor device 10 may have different types depending on where it is installed in the facility, and different types of sensor devices 10 may obtain sensing information based on different sensing units, but the sensor device 10 is not limited to this.
