Description

A kind of falling rocks monitoring and positioner for Along Railway
Technical field
A kind of device that can carry out monitoring and positioning in real time to the falling rocks of Along Railway side slope is the utility model is related to, is belonged to Monitoring technical field.
Background technology
Side slope rockfall is always the big security risk for threatening railway transportation, crash into larger falling rocks on railway or its If its object is handled not in time, locomotive and related personnel will be damaged, therefore the rockfall of Along Railway is carried out Monitoring and positioning are of great significance in real time.
Lot of domestic and international scholar has carried out numerous studies for this problem, up to the present, to railway both sides falling rocks Monitoring method is mainly the following:
(1) GPS positioning method:It is monitored using global position system, the drawback is that plant maintenance heavy workload, distinguishingly Domain can not obtain signal, and high-accuracy position system price is high, therefore can not large-scale promotion application;
(2) video imaging method:It is monitored using the method for outdoor pick-up, although the method comparison is directly perceived, is easy to Influenced by mist and sleety weather, antijamming capability is poor, it is difficult to adapt to the geological environment of complexity;
(3) fibre grating method:Although the volume production of the monitoring device based on fiber grating sensing technology, its system into This and maintenance cost are higher.
In conclusion existing falling rocks monitoring method and monitoring device there are it is such or such the problem of, it is necessary to add To improve.
Utility model content
The purpose of this utility model is that the drawback for the prior art, there is provided it is a kind of of low cost, easy to maintain and The falling rocks monitoring of strong antijamming capability and positioner, with the security risk for finding in time and excluding railway transportation.
Problem described in the utility model is realized with following technical proposals:
A kind of falling rocks monitoring and positioner, composition for Along Railway includes data analysis sending module and four Microseismic sensors, four microseismic sensors are separately mounted on four angles of rectangular area, their signal output part connects respectively The different input terminals of data analysis sending module, the data analysis sending module exchange letter with monitoring center by wireless signal Breath.
Above-mentioned falling rocks monitoring and positioner for Along Railway, the data analysis sending module include microcontroller and Wireless communication module, four input ports of the microcontroller are connected with four microseismic sensors respectively, the radio communication mold Block is connected on the serial ports of microcontroller and is communicated by wireless signal with monitoring center.
Above-mentioned falling rocks monitoring and positioner, four microseismic sensors for Along Railway is symmetrically distributed in railway Both sides.
Above-mentioned falling rocks monitoring and positioner for Along Railway, the first microseismic sensors S1 and the second microseism pass Sensor S2 is at a distance of 30-50 meters, and the first microseismic sensors S1 and the 4th microseismic sensors S4 are at a distance of 4-10 meters.
The utility model gathers falling rocks using four microseismic sensors and hits shock wave caused by ground, utilizes data point Analysis sending module judges the position of falling rocks and will send information to monitoring center.Described device is of simple structure and low cost, installation Easy to maintain and strong antijamming capability, can help the relevant personnel to find and exclude in time security risk, ensure railway transportation Safety.
Brief description of the drawings
Fig. 1 is the scheme of installation of the utility model;
Fig. 2 is the electrical schematic diagram of the utility model.
In figure respectively marked as:1st, data analysis sending module, 2, side slope, 3, falling rocks, 4, data line, U1, microcontroller, U2, wireless communication module, the microseismic sensors of S1~S4, the first microseismic sensors~the 4th, R1~R4, the first current-limiting resistance~the Four current-limiting resistances.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1 and Fig. 2, the utility model includes data analysis sending module 1 and four microseismic sensors, four microseisms Sensor is fixed on the both sides of railway and is located at respectively on four angles of rectangular area.Microseismic sensors send mould with data analysis Block 1 is connected by data line.Data analysis sending module 1 is mainly made of microcontroller U1 and wireless communication module U2.
In Fig. 1, the first microseismic sensors S1 and the second microseismic sensors S2 is at a distance of 30 meters, the first microseismic sensors S1 with 4th microseismic sensors S4 during concrete application in allowed band at a distance of 4 meters (can make the appropriate adjustments), data line 4 during installation Data analysis sending module 1 is connected to after being passed through below from rail.It is attached that data analysis sending module 1 is bolted on railway Near home, its main function are that data are carried out with analysis to calculate and send.
In fig. 2, the model MVX0608.02 of four microseismic sensors S1~S4, each microseismic sensors pass through one Current-limiting resistance is connected with power supply.
When larger rockfall 3 or other objects fall into the rectangular area of four microseismic sensors coverings from side slope 2 When, road shock, each microseismic sensors will be caused to be transferred data to after collecting vibration signal by data line 4 Data analysis sending module 1, microcontroller U1 collect vibration signal by four microseismic sensors and focus are positioned, then Hypocentral location remote data is sent to by railway monitoring center by wireless communication module U2.
In Fig. 1, when falling rocks monitoring positioning device works, the signal that monitoring center is sent sends local to by Ethernet Server, the synchronizing signal that home server produces make each multi-channel data acquisition module produce at the same time by synchronous firing line Trigger signal, each microseism detector array synchronously start gathered data.
The utility model can to around railway rockfall carry out in real time, be accurately positioned.Used microseism sensing Device high sensitivity, reaction speed is fast, and it is 25m effectively to monitor radius.The utility model is using the method for four point circular arcs positioning to pendant The rockfall for entering rail track is positioned.
The current-limiting resistance of the first current-limiting resistance in the utility model~the 4th is used for current limliting, meanwhile, also determine each microseism The operating potential of sensor.
