Design of Cable Fire Prevention Monitoring System Based on ZigBee Network

设计一种基于ZigBee网络的电缆防火监控系统,能实时、精准监测电缆火灾,并及时灭火。系统通过部署在电缆现场的烟雾和温度传感器分别采集烟雾和温度数据,经单片机转换处理后传输至ZigBee通信模块,利用ZigBee协议、ZigBee网络节点以及通信流程将温度和烟雾数据传输至火灾控制模块,实时监测电缆各位置的温度和烟雾浓度,当温度或烟雾浓度超出设定值时,及时通过ZigBee网络发出报警并准确定位着火位置,自动启动灭火部件完成灭火,实现电缆防火监控。与传统系统相比,这个系统可以通过监测电缆的温度以及烟雾浓度变化,实现电缆火灾的及时精准监控,监测精度较高,准确性较好,能够及时精准监测电缆火灾,并及时灭火。实验结果表明:该系统可以实时、有效监测电缆温度和烟雾浓度变化,并及时报警,启动电缆火灾自动灭火部件灭火,防止电缆火灾发生。

A cable fire prevention monitoring system based on ZigBee network is designed to accurately monitor the cable fire in real time,and put out the fire in time.The system collects smoke and temperature data through sensors,and deploys them on the cable site and transmits them to ZigBee communication module after being converted and processed by single chip microcomputer.Temperature and smoke data are transmitted to the fire control module by using ZigBee protocol,ZigBee network node and communication process,so as to monitor the temperature and smoke concentration of each position of the cable in real time.When the setting value is set,the alarm will be sent out through ZigBee network in time,and the fire location will be accurately located.The fire extinguishing components will be started automatically to complete the fire extinguishing and realize the cable fire prevention monitoring.Compared with the traditional system,this system can monitor the cable fire timely and accurately by monitoring the temperature and smoke concentration changes of the cable.The monitoring accuracy is high.It can timely and accurately monitor the cable fire and extinguish the fire in time.The experimental results show that the system can monitor the changes of cable temperature and smoke concentration in real time and effectively,and alarm in time,and start the automatic fire extinguishing components of cable fire to prevent the occurrence of cable fire.
