Abstract

The invention relates to a microcontroller control electro-pneumatic brake unit for locomotive brake systems and aims to achieve conversion of electrical signals of a locomotive brake system and an air brake pressure signal. The microcontroller control electro-pneumatic brake unit comprises an air circuit portion and an electrical portion; the air circuit portion mainly comprises an intake electromagnetic valve, an exhaust electromagnetic valve and a pressure sensor. The electrical portion mainly comprises a life signal module, an RS232 communication module, an analog input module, a CAN (controlled area network) communication module, a BI (batch input) module, a master control CPU (central processing unit) module, a monitoring CPU module, a high-speed electromagnetic valve drive module, an analog acquiring module and a power processing module powering the modules above. The electro-pneumatic brake units in a brake control system can automatically control train tubes, distributor valves and independent brake pressures, separately, automatically in response to control commands of the electro-pneumatic brake units, the stability of the brake control system is improved, and fault rate is decreased.

Description

technical field

[0001] The invention relates to the field of railway locomotive braking, in particular to a microcomputer-controlled electro-pneumatic braking unit for a locomotive braking system. Background technique

[0002] With the intelligentization and network development trend of the locomotive braking system, the original pure air control method in the locomotive braking system is gradually eliminated, and the locomotive braking system controlled by a microcomputer has become the mainstream of existing products. The braking control of the train by the locomotive braking system is mainly realized through the following three important modules, which are the train control module, the distribution valve control module and the individual brake control module. The command signal is converted into an air pressure signal, and the train pipe pressure, distribution valve pressure and individual brake pressure are respectively controlled.

[0003] Among them, the train pipe co...
