无线火灾报警系统设计

摘要

Fire disaster brought us immeasurable loss,and thus prevent the fire alarm has been one of the topics of concern at home and abroad.To solve problemsofthe traditional wired fire system,the authors propose a designofwireless fire alarm system based on ZigBee wireless technologyin this paper.The system uses wireless network architecture star topology,and itis divided into a central processing end and probing ends of the two parts.The central processing end use STM32F103ZET6 as the core,the probe end use STC89C52RC as the core,andthey combined with radio frequency chip CC2530 ZigBee-based technology,to achieve the need of a wide range of regional fire monitoring and alarms.After research and testing show that the system is designed for low cost,high intelligence,stable and reliable performance.%火灾灾害给我们带来了难以估量的损失,因而火灾预防报警一直是国内外备受关注的课题之一.为解决传统有线火灾系统存在的问题,提出一种基于ZigBee无线技术的无线火灾报警系统设计.系统采用星形拓扑结构的无线网络结构,并分为中心处理端和探测端两部分组成.中心处理端采用STM32F103ZET6芯片为核心,探测终端采用STC89C52RC芯片为核心,两部分同时与基于Zig-Bee技术的无线射频芯片CC2530相结合,实现了大范围区域火灾监控与报警的需要.经过研究与测试表明,该系统设计成本低、智能化高、工作性能稳定可靠.
