基于STM32的多网络人防警报终端设计

Design of Multi Network Civil Air Defense Alarm Terminal Based on STM32

摘要:

传统人防警报系统一般采用单一途径触发方式,实时性和可靠性易受限制,据此设计了多种远程方式控制警报的终端,采用STM32作为主控芯片,外围集成包括移动通讯、固话、有线以太网络3种技术途径触发多种警报；3种途径的仲裁采用先到先触发的兼容方式,并给出了终端的架构及内部设计运行原理,充分发挥了不同网络在不同环境下的优势,保障了不期灾害发生时警报的实时快速预警；同时对状态信息进行反馈,经实际使用测试,系统稳定,实时,可靠性强,为破坏性灾害发生时的成功预警提供了一种可靠方法。

Abstract:

Traditional civil air defense alarm system is normally a single pathway triggered and real time and reliability are easily Limited. A multi network civil air defense alarm terminal that use the STM32 as the main control chip is designed. It is a variety of remote control alarm terminal, including three approaches for mobile communications, fixed telephone, and Ethernet network technology to trigger alarms. Three ways of arbitration using the first come first served rule. And the terminal architecture and operation principle is proposed to guarantee the rapid and real-time warning alarm when the disaster occurred. The advantages of different networks in different environments are fully obtained and the state information can be feedback. The system is stability, real-time, high reliability through testing. It provides a reliable method for the early warning of the disaster. 
