Description
Technical field
The present invention relates to the safety guard of rail vehicle, in particular to a kind of electronics merges triggering with mechanical sensitivity device
Derailing detection device.
Background technique
Since railway speed increase, the safe operation of train is most important in China.Due to external environment variation, vehicle or route
It is not in good state, the influence for the factors such as vehicle unbalance-loading, train marshalling list or locomotive control are improper, derailing becomes safety of railway traffic
One of main hazard source, the ratio in major accident is up to 70%；And if staff does not send out in time after derailing
Existing, train will continue to travel, and derails or topples in succession to cause more vehicles, leads to fault spread, cause vehicle, cargo,
Equipment is badly damaged by sleeper, roadbed and road, or even collides with adjacent line train, gently then traffic interruptions, heavy then vehicle ruins people
It dies, not only economic loss is huge, but also social influence is severe.
It is top priority that rescue, which is resumed work, after train derailing, and scene is more chaotic, very to the true cause caused an accident
Analyze to difficult comprehensive system.Both at home and abroad in terms of forecasting research of derailing, due to prediction model not precisely, test parameters can not be accurate
Control, extreme operating condition test such as are difficult to realize at the influence of factors, and causing to judge algorithm and criterion cannot accurately reflect that derailing is inclined
To rate of false alarm is higher, not very practical.
Therefore it installs derailing detection device additional ON TRAINS, by the Anomalous dynamics and sign in detection operational process, is going out
Emergency braking is carried out immediately after now derailing, to prevent that secondary injury is a kind of applicable method.
Several derailing detection devices are developed both at home and abroad at present, and railway is transported reducing derailing loss, reducing derailment accident

Rail detection device needs many high prices, high-precision sensor, unrealistic from the viewpoint of the cost.Therefore in newly built railway
During debugging or trial operation, since line conditions are not satisfactory, derailing event happens occasionally, and construction party can not carry out vehicle
Repacking usually monitors the safe operation situation of train in last vehicle of train by manually visualizing, and reliability, real-time are poor.
2, structure is complicated, and machining accuracy is high, and assembly difficulty is big.Such as the derailment detector that certain external company develops has 4
To the valve seat and working chamber matched, mutual installation accuracy is very high, and to dimensional accuracy, flatness and the accuracy of form and position
Also have strict demand, process, assemble it is extremely difficult.
3, there is lag in the response time.In the derailing detection device designed, the equal position of mass block of vibration acceleration is detected
In the lower section of valve seat；When practical derailing occurs, always working chamber first sinks, and derailing letter can be just issued after car body lands
Number, cause system response to lag, delays emergency braking and make-up time.
4, reliability is not high, is easy to produce maloperation.For Purely mechanical derailing protective device, branch pipe leaks frequent occurrence
Let out, pull ring deformation, lose, damage etc. failures, make derail brake apparatus failure, buried hidden danger to traffic safety.In addition, vehicle
The factors such as uneven suitable excitation of suspension operation, Rail Surface slight amplitude will lead to electronic type derailing detection device and produce in short-term
Raw wrong report, influences safety and the comfort of train operation.

Stating analysis of derailment unit (4) includes:
Signal receiving unit (401), trigger signal and acceleration transducer for being sent received from reset stroke switch (303)
(315) the vertical vibration signal sent；
Signal judgment module (402), for judging whether to receive the trigger signal of Self-resetting travel switch (303) transmission, if
It is then to send and instruct to signal identification module (403)；
Signal identification module (403) calculates separately mean value, the arteries and veins of vibration for identifying to received vertical vibration signal
Dynamic value and action time, and draw the response spectrum of vibration；
Signal processing module (404), for comparing the mean value, pulsating quantity and action time of vibration with corresponding threshold value respectively
Compared with, and judge whether to be all larger than threshold value, it is instructed if so, being sent to signal management module (405)；
Signal management module (405) for the effect of vibration according to Calculation of response spectrum vehicle, and judges whether calculated result is greater than
Threshold value, if so, sending derailing signal to drivers' cab by emergency brake signal line (8).
10. the derailing detection device that electronics according to claim 9 merges triggering with mechanical sensitivity device, which is characterized in that
The signal management module (404) calculates the effect of vibration P of vehicle according to the following formula:
P=α W
Wherein, α is that vibration influences coefficient,W is the weight that vehicle is equipped at connecting plate (1).
