摘要
针对以往火情监控系统往往采用有线组网方式,具有布线繁琐、扩展性差以及维护困难的问题,提出了一种基于物联网和ZigBee无线通信技术的图书馆火情监控系统设计方案.首先,设计了系统的总体构架,将系统分为感知层、传输层和应用层3个部分;然后,给出了系统硬件设计方案,对ZigBee传感器节点、路由器以及协调器均进行了设计;最后,对网络拓扑结构、各节点的软件流程、MAC层协议以及监控主机软件进行了描述和分析.通过系统测试表明文中系统可以正确、实时地采集图书馆温度、湿度和烟雾等火情信息,并具有部署方便、成本低的优点.
Aiming at the fire monitoring system,the wired model has been studied to remove the defects of wiring cumbersome,low expansibility and maintain difficulty,and a system based on Internet of things and ZigBee communication technology has been proposed.Firstly,the main structure of the system has been designed,and the system divided to sensor layer,transport layer and application layer.Secondly,the system hardware design has been given and the sensor node,router and coordinator been designed.Finally,the topological structure,software flow of all nodes,MAC layer and monitoring software have been described and analyzed.The system test shows the system in our paper can correctly and in-timely collect the temperature,humidity and smoke information in the library and have the convenient deployment and low cost.
