基于以太网供电技术的火灾探测系统研制

摘要

介绍了一种基于以太网供电技术的火灾探测系统设计方案。方案采用以太网供电技术，实时采集火灾参数模拟量，并通过RJ45网络接口，应用TCP/IP技术传输给服务器做进一步数据处理，便于火灾虚拟场景再现和火灾趋势预测，降低了火灾误报率，并能实现火灾的可靠监测，同时又通过网口为火灾探测节点提供电源能量供给，简化了系统的硬件结构，方便电路板的布局布线。%A fire detection system based on PoE ( Power over Ethernet ) technology is introduced .Real-time analog fire parameters are collected by adopting the proposed new technology .With the application of TCP/IP tech-nology , the data are transferred to the server for further processing via RJ-45 network interface , which makes it easy to reproduce fire virtual scene and forecast fire trend .The system reduces the distorted fire rate and makes fire moni-toring reliable .An energy supply is also provided to fire detection node through the Ethernet port , which simplifies the hardware structure of the system and facilitates the circuit board layout.
