摘　　要：针对地铁车站火灾报警系统实时性的要求,设计了一种基于单片机技术的地铁车站火灾报警系统,给出了监控系统的结构。选用了80C51单片机作为系统的主控制器和火灾环境数据采集节点的控制器;选用基于nRF24L01的无线通信芯片作为传感器节点与火灾报警节点间的数据通信。给出了车站火灾数据采集节点、火灾报警主节点电路,设计了以二次加权融合的传感器数据处理算法,提高了系统检测与控制精度。运行结果表明,该系统稳定可靠,抗干扰,能耗低,体积小,成本低,为地铁车站火灾报警提供了一种新技术。A subway station fire alarm system based on SCM was designed to meet its real-time requirement and the structure of the monitoring system was presented. 80C51 was chosen for the main controller of the system and the controller of nodes for fire alarm environment data collection. Wireless communication chip nRF24L01 was used for data communication between the sensor node and the fire alarm node. Electric circuits for station fire alarm data collection nodes and fire alarm main nodes were presented and algorithm based on dual-weight fusion for sensor data processing was designed in order to improve the detection and control accura- cy of the system. Experimental result showed that the system is stable, reliable, anti-jamming, low in energy consumption, small in volume and low in cost. Therefore, it provides a new technology for subway station fire alarm.
