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.
