Abstract

The invention relates to a system for monitoring potential geological disasters such as dangerous rock slide, mountain landslide and the like at two sides of a railway based on a wireless sensor network system, and the system provided by the invention comprises sensor detecting devices, a solar battery, a data acquisition processing and radio frequency transceiver, relay nodes, a gateway and a background processing system which are embedded at the two sides of the railway, wherein the geological information at the two sides of the railway is obtained through the sensor detecting devices; the information data is transmitted to the adjacent nodes through the radio frequency transceiver with the frequency range of 2.4GHz and finally transferred to a monitoring center through GPRS (Global Packet Radio Service); and after processing the data, the monitoring center informs a train of the condition of whether a disaster occurs or not through the GPRS, thereby effectively preventing railway accidents from occurring.

Description

Based on the railway of wireless sensor network endanger along the line stone and landslide disaster monitoring system
Technical field
The present invention is the system and device of under the system of wireless sensor network the geology potential safety hazard of railway periphery existence being monitored, and is exactly a wireless alarm system in simple terms.
Background technology
Railway safety inspection along the line for a long time is a very difficult job, especially the investigation to geological disaster hidden danger along the line comprises that danger stone tumbles and landslide disaster, and be subjected to the influence of special violent earthquake and extreme weather disaster recent years, geological disasters such as railway avalanche along the line, landslide, mud-rock flow still are the pilosity trend that takes place frequently, and have a strong impact on railway operation, construction and life property safety of people along the line.The precautionary measures mainly were personnel inspections in the past, and so not only labor intensive also can't be carried out early warning to potential risk in real time, and effect is unsatisfactory.
Summary of the invention
The objective of the invention is to invent a kind of monitoring system of wireless sensor network of utilizing railway potential geologic hidden peril along the line is monitored automatically, and in time early warning information is sent to railway administration department.Whole process is also carried out fully automatically in real time, and monitoring efficient and accuracy all will be greatly improved.
Technical scheme of the present invention is to form like this: this system comprises that the railway both sides bury sensor detecting device underground, data acquisition process that is connected with checkout gear and radio-frequency (RF) transceiver, and the solar cell of giving transducer and data processing and radio-frequency (RF) transceiver power supply, the via node that is used for data forwarding, the GPRS module that is used for remote transfer of data, the gateway and the background processing system that also have data finally to be pooled to.
When the railway both sides occur that danger stone slope is moved or when the risk factor of geological disaster such as big rainstorm weather occurring bringing out easily, corresponding sensor detecting device can get access to corresponding information data, this information data carries out simple data processing by Acquisition Processor and the radiofrequency launcher by frequency range 2.4GHZ is transmitted into adjacent via node, finally be sent to Surveillance center by GPRS, whether Surveillance center handles the back to data has disaster to take place by the GPRS train notified.The present invention has following advantage: (1) can monitor the geology active situation of deathtrap in real time, in time sending early warning information (2) can work under the situation of unattended duty for a long time, it is reliable to save great amount of manpower resource (3) system configuration, and cost is low, and the usability scope is wide.
In such scheme, sensor device can detect the sliding condition on danger stone slope with obliquity sensor, in conjunction with rain sensor and soil moisture sensor monitoring rainfall and surface water content, obliquity sensor and data acquisition process and radiofrequency launcher all are installed in the pvc pipe, and pvc pipe is inserted into face of land certain depth, soil moisture sensor also is inserted in the face of land, and rain sensor is installed in spacious area on every side, and all transducers all are connected to digital sampling and processing.
Description of drawings
Fig. 1, workflow diagram of the present invention.
   
Embodiment
 
With reference to Fig. 1, the present invention is at first by the inclination angle, rainfall, the soil moisture sensor image data, these three kinds of transducers are exported corresponding signal by testing circuit separately respectively, this signal is passed on the data acquisition board by data wire, and send by radiofrequency launcher, transducer and data acquisition and radiofrequency emitting module are formed a node, the zone of geology in evil take place near will being placed on railway in this node easily, obliquity sensor is placed in the top of a pvc pipe, pvc pipe vertically is inserted in the face of land in order to monitor the displacement situation on the face of land, rain sensor is placed on no shaded areas, soil moisture sensor is imbedded the place of face of land 3-5 inch, and data acquisition and radiofrequency emitting plate are placed in spacious, are not subject to the place of disturbing, all transducers are all by solar cell for supplying power, and solar cell is placed on spacious no shaded areas.After data acquisition board collects data, carry out simple process to data, if data exceed the critical range value, expression has disaster to take place, then node sends data immediately.Node data is sent to nearest gateway to carry out data and gathers, if distance is far away, then can be dealt into via node earlier, sends to gateway by via node again.Gateway sends to packing data on the handheld devices such as Surveillance center or mobile phone by GPRS after receiving the data of each node transmission again, notifies the relevant personnel up-to-date geology situation of change, carries out and carries out disaster alarm and preventing and controlling.
Above-described node can be arranged a plurality of, can carry out data between node and node mutually sends, all nodes are just formed a wireless network, and this network can can't not worked because of the damage of a node, and the structure of a plurality of nodes makes monitoring more accurately and reliably.
Above-described radiofrequency emitting module is in resting state at ordinary times, saving power supply energy, if the data that collect in normal range (NR), then node sent a secondary data every 15 minutes, only just can send in real time when data exceed critical value.
Above-described Surveillance center is presented at data in real time on computer or the screen after receiving data, and can further analyze data, and data also can send on the handheld devices such as personal mobile phone in addition, realize Monitoring Data anywhere or anytime.In case have disaster to take place,, remind the train preparation of taking refuge just by the train of the existing avenues of communication notice of railroad operation.
