西门子S7-200 SMART PLC在气体检测报警系统中的应用设计

Gas Detection and Alarm System Based on S7-200 SMART PLC

为满足气体检测仪在保障密闭环境下的操作人员人身安全更高效更智能的要求下,实现就地、远程双报警的功能,设计了气体检测报警系统。利用S7-200 SMART的RS485通讯功能采集现场气体检测仪信号,进行处理并采用最优的程序化设计,实现高效报警功能。系统投入使用后,其智能安全性有极大的提高。

The gas detection and alarm system is designed to meet the requirements of the gas detector to ensure the operator's personal safety in a closed environment,which is more efficient and intelligent,and to realize the local and remote dual alarm functions.The RS485 communication function of S7-200 SMART is used to collect the signal of the field gas detector,process it and adopt the optimal programming design to realize the efficient alarm function.After the system is put into use,its intelligent security has been greatly improved.
