Abstract

The invention provides a distributed locomotive electronic brake control system comprising a communication unit, a brake controller, a locomotive main control unit, a brake control cabinet and a brakedisplay unit, wherein the brake controller, the locomotive main control unit, the brake control cabinet and the brake display unit are connected through the communication unit. The brake control cabinet comprises a brake control unit, an electric air control unit, a valve driving mechanism and a brake executing mechanism; the brake control unit controls the valve driving mechanism according to control information of the brake controller, the locomotive main control unit and the brake display unit; and the electric air control unit controls the brake executing mechanism according to the control information of the brake controller, the locomotive main control unit and the brake display unit and data information of the brake executing mechanism. According to the invention, the integration level of the electronic brake control system and the range of fault influence are reduced, the complexity of the system is reduced, the maintenance is convenient, and the reliability of the electronic control system is improved.

Description

technical field [0001] The invention relates to the technical field of locomotive brake control, in particular to a distributed electronic brake control system for locomotives. Background technique [0002] The electronic brake control system is the core of the locomotive brake system. Its main function is to receive the brake commands issued by the driver's brake controller and the locomotive main control system, collect the signals of the balanced air cylinder pressure sensor, the signal of the train pipe pressure sensor, and the independent braking system. Dynamic pressure sensor signal and total wind pressure sensor signal, etc., and collect the logic signal sent by the locomotive main control unit, through mathematical calculation and logic operation, control the train pipe pressure, locomotive brake cylinder pressure and individual brake pressure, and realize automatic braking , independent braking, emergency braking, penalty braking and braking reconnection and other ...
