Integrity detection circuit and method for reconnecting marshalling of rail engineering vehicles

Abstract

The invention discloses an integrity detection circuit and method for reconnection grouping of a rail engineering truck. The integrity detection circuit comprises N sections of compartments, wherein each section of the compartment comprises an integrity detection circuit; the integrity detection circuit comprises a switch, a relay coil, a control power supply auxiliary contact, a first reconnection cable, a second reconnection cable, a third reconnection cable, a control power supply positive wire and a control power supply negative wire, wherein the control power supply positive wire is connected with the first reconnection cable by the switch; the control power supply positive wire is connected with a control system by a relay contact 2; the first reconnection cable is connected with the control power supply negative wire by the relay coil; the control power supply auxiliary contact is connected with the switch and the relay coil in series; the n compartment is reconnected and grouped, and the first reconnection cable and the third reconnection cable in reconnection sockets at the two ends of a reconnected and grouped train are in short circuit; the circuit can be used for rapidly and simply detecting whether the rail engineering truck has the faults of hook breaking, hook releasing, train separateness and the like.

Description

technical field [0001] The invention relates to the field of control of rail locomotives, in particular to an integrity detection circuit and method for reconnection marshalling of rail engineering vehicles. Background technique [0002] At present, the detection method of the tail control device is usually used in the operation of electric locomotives. The principle is to judge the integrity of the train by detecting the wind pressure at the tail of the train. However, the anti-interference ability of the tail device is poor, and the abnormality of the wind pressure at the tail may be caused by many reasons. Judging the integrity of the train by wind pressure also has the disadvantages of slow response speed and low detection accuracy. [0003] The integrity of the train can also use the detection system combined with wind pressure sensor, GPS positioning module and acceleration sensor. This system can effectively detect the separation of trains and has high detection accu...

However, the anti-interference ability of the tail device is poor, and the abnormality of the wind pressure at the tail may be caused by many reasons. The wind pressure is used to judge the integrity of the train, and there are disadvantages such as slow response speed and low detection accuracy.

[0003] The integrity of the train can also use the detection system combined with wind pressure sensor, GPS positioning module and acceleration sensor. This system can effectively detect the separation of trains and has high detection accuracy, but the cost of this system is relatively high, and GPS does not Suitable for use in the working environment of underground tunnels
