| 摘 要： | 设计了基于无线传感器网络的多参数无线火灾探测节点,实现对温度、湿度和烟雾的自动探测,通过多参数符合探测方法来降低火灾误报率,实现对火灾的可靠监测.针对火灾特征参数多跳传输提出一种基于CSMA/CA机制的最短路径路由算法,探测器能自动组网实现对火灾特征参数的无线实时监测.实验结果表明,探测器单跳通信距离最远可达100米,多跳通信每跳传输延时约50 ms,对火灾烟雾响应达到I级灵敏度,湿度参数可有效消除水汽引起的火灾误报.

| Abstract: | Multiparameter fire detection nodes based on Wireless sensor network is designed,which can detect temperature,humidity and smoke concentration.The distorted fire rate is decreased with multiparameter coincidence technique.And a shortest path routing algorithm is proposed according to multi-hop transceiver based on CSMA/CA principle;the sensor nodes can connect each other automatically,the sensor data can be transmitted within minimum hops.Using this type nodes,a real-time fire monitoring system is built up.... |
