摘　　要：可燃性气体报警控制器基于ARM Cortex-M3内核的微处理器设计,采用RS-485通信方式,可连接多个探测器节点。当检测到监控场所中气体浓度达到危险极限时,输出相应的报警信号和控制信号,提示操作人员及时采取安全处理措施。重点介绍了该设备的硬件组成结构和软件设计流程。测试结果证明,该气体报警控制器的设计具有较高的实时性和可靠性,且具有安装方便、线路成本低等优势。Flammble gas alarm controller design of microprocessor based on ARM Cortex-M3 kernel, the use of RS-485 communication, can be connected with a plurality of sensor nodes. When the gas concentration in the monitoring place reaches the limit of danger, the output of the corresponding alarm signal and the control signal, prompt the operator to take safe treatment measures in time. The hardware structure and software design flow of the equipment are introduced in this paper. The test results show that the design of the gas alarm controller has the advantages of high real-time performance, reliability, convenient installation, low cost and so on.
