Abstract:
     The fire-proof safety alarm system for passenger train is characterized by that a safety alarm formed from micro-processing control system circuit consisting of alarm press-button control circuit indicator light circuit, 8031 chip microprocessor, 74Ls373 latch and EPROM2716 program memory, filter coupling circuit and shell body is mounted on the wall of conductor's cubicle of every carriage. The alarm signal of every carriage is analyzed and processed by micro-processing control system, passed through audible circuit, broadcast line and modulation/demodulation circuit, and transmitted to all conductors of all carriages so that it can timely and accurately eliminate fire, banditry and other hidden peril, etc..
