【摘要】：针对目前环境空气质量监测系统大多操作复杂、显示控制单一及不能远距离报警的弊端,设计了基于北斗和ZigBee的环境空气质量监测系统,该系统可以在远距离的情况下自动完成组网,实现对空气中的温度、湿度和烟雾空气指标的监测和预警功能;系统中的采集端主控模块完成对多种传感器采集的信息进行显示与参数的设置工作,采用数字式温湿度传感器和离子烟感实时采集空气中的监测对象,空气指标数据通过每个子模块中的ZigBee路由及终端节点组成的无线局域网进行数据的传输,所有信息汇总后由ZigBee协调节点模块经北斗卫星网络进行实时传输,从而实现对远程空气质量监控的目的;经实验证明该系统温度误差值小于2.5%,湿度误差值小于等于4%,具有传输稳定、使用领域广阔和覆盖面积大等优点,符合未来智能报警领域的发展趋势,具有一定的实用价值和可推广性。
[Abstract]:In view of the disadvantages of the current air quality monitoring system with complex operation, single display control and no remote alarm, an ambient air quality monitoring system based on Beidou and ZigBee is designed. The system can automatically network at a long distance and realize the monitoring and warning function of air temperature, humidity and smog air index. The main control module of the system completes the display of the information collected by various sensors and the setting of the parameters. The digital temperature and humidity sensor and the ion smoke sensor are used to collect the monitoring objects in the air in real time. The air index data is transmitted through the wireless local area network (WLAN) composed of ZigBee routing and terminal nodes in each sub-module. After all the information is summarized, the ZigBee coordination node module is transmitted in real time via Beidou satellite network. It is proved by experiments that the temperature error value is less than 2.5, the humidity error value is less than or equal to 4, and the system has the advantages of stable transmission, wide application field and large coverage area, etc. In line with the development trend of intelligent alarm field in the future, it has certain practical value and extensibility.
