In civil defense engineering, three anti-ventilation, air conditioning dehumidification, power supply and other electrical control equipment have long distance, distributed monitoring area and are not convenient for centralized monitoring. To improve the level of civil air defense system of automatic monitoring, enhance the system's rapid response ability, adapt to the need of modern war, this paper based on data communication problems of distributed electrical system in civil defense engineering, combined with the low communication rate and high security requirements in civil defense engineering, puts forward the communication solutions based in Siemens PPI fieldbus, configures the communications PLC which has powerful functions, compiles multipoint PPI communication program, designs remote monitoring system and gives results of test analysis when it is running. Actual operation results show that the communication system of civil defense engineering based on Siemens PPI fieldbus has fast communication speed, low error rate, strong expansibility and other advantages..
