Embodiment Construction

[0019] Such as figure 1 As shown, the brake cylinder pressure control system of Embodiment 1 of the present invention is applied to the locomotive brake machine, including BCU, switching solenoid valve ( figure 1 W in), action tube sensor ( figure 1 P / E in is the pressure sensor), train pipe control BP module (the module in the brake machine, connected with the train pipe), brake cylinder pre-control EP module, air distribution valve (air action valve), action valve, brake cylinder.

[0020] The BCU is connected with the train control BP module and the brake cylinder pre-control EP module; both the BCU and the brake cylinder pre-control EP module are electrically connected with the switching solenoid valve; The action valve on the action pipe that the cylinder communicates with. The pressure sensor is installed in the action pipe between the switching solenoid valve and the action valve; the pressure sensor is electrically connected with the BCU.

[0021] The BCU detects t...

Abstract

The invention discloses a rail transit vehicle and a brake cylinder pressure control system and method thereof. The brake cylinder pressure control system comprises a BCU, and the BCU is connected with a train pipe control BP module and a brake cylinder pre-control EP module; the system is characterized in that the BCU and the brake cylinder pre-control EP module are electrically connected with aswitching electromagnetic valve; and the switching electromagnetic valve communicates with an air distribution valve and an action valve mounted on an action pipe communicating with a brake cylinder.According to the system, the problem that when the brake cylinder pre-control EP module breaks down, the action pipe has no pressure or the pressure cannot be relieved, so that a locomotive has no brake cylinder pressure or the brake cylinder pressure cannot be relieved is solved, and safe operation of the locomotive is ensured.

Description

technical field [0001] The invention relates to the field of rail transit, in particular to a rail transit vehicle and its brake cylinder pressure control system and method. Background technique [0002] The electropneumatic braking method widely used in domestic locomotive braking uses compressed air as the driving force for braking, and changes the pressure of the compressed air to control the braking of the train. In practical applications, in order to quickly respond to the brake and release performance of the brake cylinder when the brake is in the usual braking and release conditions, the brake is put into the electronic distribution valve, and the brake cylinder is pre-controlled (that is, the BCU according to the train A value calculated by decompression of the brake cylinder, the pressure of the brake cylinder is determined by controlling the pre-control value of the brake cylinder) to control the pressure of the acting pipe, and the acting pipe is then amplified by...
