燃气泄漏监测报警控制系统的设计与实现

Design and Implementation of Gas Leakage Monitoring and Alarm Control System

针对普通报警控制系统的通信传输能力低、组网个数少的局限性,采用4G全网通、LoRa和蓝牙混合组网的无线通信技术,设计研发了由可燃气体监测节点、网关、监控中心组成的可燃气体报警控制系统,提出了系统网络结构,给出了报警控制器和网关的硬件电路,通过三级通信网络实现了可燃气体监测现场和远程双重报警功能,同时现场自动开启联动控制装置切断气源,预防危险情况的发生。试验结果表明,系统报警控制可靠、稳定,具有良好的实用价值。

For ordinary alarm control system for communication and transport capacity is low,the network number less limitations,this paper puts forward the 4G netcom,LoRa and bluetooth network of wireless communication technology,develops the combustible gas alarm control system composed of combustible gas monitoring node,gateway and monitoring center,and designs the system network structure,and gives hardware circuit of alarm controller and gateway.Through the three-level communication network,the dual alarm function of combustible gas monitoring on site and remote is realized.At the same time,the linkage control device is automatically opened on site to cut off the gas source and prevent the occurrence of danger.The test results show that the alarm control system is reliable,stable and has good practical value.
