Abstract: In order to solve the lack of an integrated control system with complete functions and high reliability in China's underground pipeline gallery at the present stage，the emergency system is weak，and the safety and reliability are poor． We propose an integrated control system for underground pipe corridors based on CAN ( Controller Area Network) Bus comunication． After several simulation experiments and test platform tests，this system is more reliable and convenient than the integrated control system applied to underground pipe corridors in China at this stage． Extended，lower cost，etc．

Key words: controller area network ( CAN) bus, total distribution control, anti-jamming of intelligent nodes
