摘要
介绍了总线制气体多路巡回检测系统的设计及工作原理。由RS－485串行总线构成主从工作方式，可以与上位PC机连接，形成子机、主机、PC机三级结构，使系统的风险性分散，安全性提高。
：The design and working principles of the bus gas-detecting alarm system are given in this paper．The system can work in the master-slave mode with the RS－485 bus and can also be connected to PC．Thus the slave device，the master device and PC make up a 3-class structure．In this way the risk of the system is dispersed and security ensured．
