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 technology,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 monitoring 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.
