Abstract
The invention discloses a USSN (ultra-scale sensor network) wireless network vibrating string type data acquisition instrument, and relates to the technical field of civil engineering, in particular to the safety health monitoring industry. The USSN wireless network vibrating string type data acquisition instrument comprises more than one sensor node, a mobile communication base station, a mobile GPRS (general packet radio service) unit and a monitoring center, wherein the mobile communication base station is communicated with the sensor nodes and the mobile GPRS unit through wireless signals; the mobile GPRS unit is connected with the monitoring center; each sensor node is provided with an independent acquisition circuit and an independent battery power supply, and mainly comprises a sensor, a signal conditioning and acquisition module and a USSN node; each sensor is provided with four core wires namely two vibrating string signal wires and two digital thermometer signal wires. According to the USSN wireless network vibrating string type data acquisition instrument, the problem of difficulty in field wire arrangement is solved; signal cables are eliminated from all sensors, and the sensors only need to be installed on components according to a corresponding method; the system is particularly suitable for dangerous and complicated field environments in which wires are quite difficult to arrange.
Description
Technical field
The present invention relates to technical field of civil engineering, be specifically related to safety and Health monitoring industry.
Background technology
The data test means of vibrating string type sensor all still adopt centralized collection at present, each sensor needs signal cable to be connected with vibratory string data acquisition equipment, because layouting of sensor relatively disperses, cause like this on-site signal cable relatively chaotic, be not easy to search problem on the one hand, complicated site environment also easily damages cable on the other hand, and the cost of a large amount of signal cables is not low yet.For the inconvenient place that powers, scene, can only adopt the power supply such as accumulator, sun power, if power-supply system goes wrong, whole system all can be paralysed, and hidden danger is very large, and maintenance cost is also high.
Summary of the invention
The object of the invention is: a kind of USSN wireless network type vibration wire data collecting instrument is provided, to overcome the defect of prior art, by adopting the complete energy-conservation ultra-large technology of wireless sensing network of current maturation, save the workload of on-the-spot a large amount of wirings, and each sensor node has the battery supply of oneself, do not need on-the-spot power supply, this network has ad hoc network, can freely find optimum data transfer path, for what occur in long-time observation process " bad point " (certain node occurs abnormal) phenomenon, can not affect whole monitoring system, guarantee the reliability of system.
According to above-mentioned purpose, the technical solution adopted in the present invention is: a kind of USSN wireless network type vibration wire data collecting instrument, it is characterized in that: it comprises sensor node, mobile communication base station, mobile GPRS and Surveillance center, mobile communication base station is connected by wireless signal with sensor node, mobile GPRS, and mobile GPRS is connected with Surveillance center.
Described sensor node has more than one, has respectively independently Acquisition Circuit, battery supply independently.
Described sensor node is mainly made up of sensor, signal condition acquisition module and USSN node.
Described sensor is furnished with for quad, and two is vibratory string signal wire, two signal wires that are digital thermometer.
Compared with prior art, advantage of the present invention and beneficial effect are:
1, the invention solves the problem of field wiring difficulty, all the sensors has all saved signal cable, only sensor need be arranged on member according to corresponding method;
2, native system is particularly suitable for on-the-spot danger, and complexity is difficult to the environment connecting up.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention theory diagram;
Fig. 2 is embodiment of the present invention sensor node principle of compositionality block diagram;
Embodiment
In conjunction with Fig. 1, Fig. 2, for a kind of USSN wireless network of the present invention type vibration wire data collecting instrument embodiment theory diagram, it comprises sensor node, mobile communication base station, mobile GPRS and Surveillance center, mobile communication base station and sensor node, mobile GPRS is connected by wireless signal, mobile GPRS is connected with Surveillance center, the present invention is on the basis of original vibratory string data acquisition function, consider ultralow Consumption, and in conjunction with USSN super low-power consumption short-distance radio module, each sensor has oneself independently Acquisition Circuit, independently battery, like this in the time that multiple sensor points in system have an appearance abnormal, can not affect the work of whole system, the equilibrium of the whole network node power consumption is the feature of USSN module, the working time of meeting Hoisting System entirety like this.
As shown in Figure 1, in reality, on-the-spot network structure can change according to actual conditions the whole network of basic system to some extent.Such as occurring wireless networking and on-the-spot RS485, the phenomenon that CANBUS coexists.
Actual data acquisition node is by sensor, signal condition acquisition module, and USSN node forms.
Wherein vibrating string type sensor is generally 4 heart yearns, and two is vibratory string signal wire, two signal wires that are digital thermometer.
The function that signal condition acquisition module completes is for by collection of simulant signal and complete conversion, and computing, obtains actual frequency values.
The collection of whole signal condition module and data processing operation process are less than 1 second, and the power consumption control of node comes from waking up and sleep signal that USSN module provides.
The instantaneous power consumption of vibratory string class collecting device is less than 100mA, peak point current 1.1A (momentary pulse pumping signal is the excitation source signal of sensor).
The operation period of whole system is generally once to gather each hour, without synchronous requirement.
The interface that type vibration wire collecting device provides: UART, SPI.
Practical operation can be considered the USSN Module-embedding vibratory string signal regulating panel that Beijing Wei Xun amethyst Science and Technology Ltd. is produced, and the lithium battery of single-unit capacity 3000mAH is considered in node power supply.The power supply master switch open and close signal of whole signal regulating panel is provided by USSN module, should be noted that on signal regulating panel and has DCDC module, need to, sending before acquisition, reserve suitable T start-up time.
