Description
Technical field
The present invention relates to monitoring system, specifically relate to a kind of track circuit traffic safety monitoring system that can carry out monitoring to flood, mud-stone flow disaster and rail break and report to the police.
Background technology
In recent years along with the fast development of railway, railway security is more and more subject to people's attention, and the testing and alarm of Railway Disaster also becomes more and more important problem.Flood Control in Railways at present for rainy season is prevented waterlogging and is located in the Geological Hazards of debris prone district in mountain area, if still adopt staff to patrol and examine the orthodox method of investigation piecemeal, a large amount of human resources need be consumed, and have efficiency not high, can not the defect of Real-Time Monitoring and warning, especially when the night in rainy season from far-off regions, to need patrolling and examining frequently, at this moment difficulty will increase greatly.
Current warning device such as GPS displacement detecting, up short technology for detection etc. have the following disadvantages:
1) need add more external equipment on original equipment, cost is higher.
2) functionalization is single, often can only detect a certain disaster.
3) antijamming capability is weak, is vulnerable to the impact of non-disaster factors, causes wrong report, wasting manpower and material resources; Wherein some detection technique also has complicated operation, cannot transmit the shortcoming of the condition of a disaster relevant information in time simultaneously.
summary of the invention:
The object of the present invention is to provide one can Real-Time Monitoring track circuit driving whether safety can find break rail, flood and mud-stone flow disaster, use safety, working stability, simple to operate, cost is low, the track circuit traffic safety monitoring system of long service life.
The object of the present invention is achieved like this:
A kind of track circuit traffic safety monitoring system, feature is: comprise sensor detection module, signal processing module, radio frequency transmitter signal and Signal reception processing module, wherein:
Sensor detection module comprises intelligent responder, signal, level alarm for water and grille guard module, and signal processing module comprises microcontroller and aggregation node, and Signal reception processing module comprises signal receiving device and warning device; The Signal transmissions that sensor detection module gathers by aggregation node is to microcontroller, microcontroller is after Logic judgment, if reach alert if, the signal that sensor detection module collects by microcontroller passes through radio frequency transmitter signal, transfer to the signal receiving device in the signal receiving device and train driver cabin being arranged on making station control room in the mode of gsm wireless network, signal receiving device is connected with warning device.
Grille guard module is be arranged on grille guard for detecting the vibration sensor of mud-stone flow disaster.
Signal receiving device is the communication receiving device based on GSM-R system.
Level alarm for water comprises top board, shell, water outlet, cursory, water inlet and contact, wherein: be provided with latticed water inlet in the bottom of the shell of tubular, middle part is the water outlet of paliform, it is cursory to be provided with in the enclosure, the aluminium foil for conducting electricity is posted at cursory upper surface, two switch contacts place the bottom of a small cylinder under the top plate, the aluminium foil of upper surface can simultaneously with two contact, by two contact conductings.
Four kinds of measurement mechanism cooperation detection track circuit safety in sensor detection module, detection case is divided into following five kinds of states:
1, intelligent responder detects the signal that train passes through, signal reduces to be not enough to maintain relay work because of electric current in track circuit, signal is shown as red light, level alarm for water does not reach threshold value, during the response of grille guard module alarm free, be train process in such cases, radio frequency transmitter signal is in state of activation.
2, intelligent responder does not detect that train is by signal, and signal is shown as red light, and level alarm for water reaches threshold value, and during the response of grille guard module alarm free, in such cases for producing flood damage, radio frequency transmitter signal is in state of activation.
3, intelligent responder does not detect that train is by signal, and signal is shown as red light, and level alarm for water does not reach threshold value, and during the response of grille guard module alarm free, in such cases for rail is in broken rail state, radio frequency transmitter signal is in state of activation.
4, intelligent responder does not detect that train passes through signal, signal is shown as green light, and level alarm for water does not reach threshold value, during the response of grille guard module alarm free, this kind of situation be in a safe condition and this kind of situation of track circuit for pass through without train, radio frequency transmitter signal is in dormant state.
5, intelligent responder does not detect that train is by signal, and signal is shown as red light, and level alarm for water does not reach threshold value, and when grille guard module has an alarm response, in such cases for producing mud-stone flow disaster, radio frequency transmitter signal is in state of activation.
Five kinds of detected states of track circuit, be based on the whether safety of the signal detect lines Car Track in track circuit, when track circuit detects that Crane Rail is in non-secure states, namely signal is shown in red, again according to other aiding sensors: level alarm for water, grille guard module, intelligent responder, judge that track is in train and is occurred by state or disaster, and the kind that disaster occurs can be judged: rail ruptures, flood damage occurs, mud-stone flow disaster occurs, and is convenient to the carrying out of subsequent rescue work.
Intelligent responder can detect that the signal that train passes through is because train produces resonance through the frequency of out-of-date generation and the frequency of intelligent responder, activates intelligent responder; Signal display red light is because track circuit short circuit or open circuit make the undercurrent on relay to continue to maintain relay work, thus makes the number of achieving one's ambition machine be shown as red light, represents and forbids that train passes through; It is because buoyancy makes cursory rising contact trigger circuit conducting with firing point that level alarm for water reaches threshold value; Grille guard module have alarm response be due to grille guard thrust by mud-rock flow time, make its circuit now be in open-circuit condition, to microcontroller transmit alarm message.
When radio frequency transmitter signal is in state of activation, will to Signal reception processing module send there is disaster kind relevant information.
Major advantage of the present invention is as follows:
A, can effectively reduce patrol and examine work business personnel work capacity.China is vast in territory, with a varied topography, in rainy weather situation, often through at interval of a period of time dispatch personnel check along the line railway, guarantees railway operation safety.Native system energy Timeliness coverage the condition of a disaster also gives the alarm, and can reduce the work capacity of work business personnel to a great extent.
B, stable work in work of the present invention, cost is low, efficiently utilize railway existing equipment, only add a small amount of external equipment and can complete auxiliary monitoring, and only utilize existing equipment track circuit and intelligent responder can judge Crane Rail whether safety, after a small amount of external equipment of interpolation, can also specifically judge disaster kind, and can utilize sender unit that generation disaster kind is sent to Signal reception processing module, complete calamity forecast.
C, functional diversities can judge the kind of the condition of a disaster in time, can provide important information for the repairing work of disaster railway, reduce the generation of railway accident.
