摘要
针对目前粮仓监测系统存在的布线困难、扩展性差和成本高的缺点,基于无线传输思想,给出了可以实时监测O2、CO2、温度、湿度等参数并越限报警的粮仓监测系统设计方案。该系统采用分布式网络结构,通过各传感器节点对O2、CO2、温度、湿度数据进行采集和传送,将采集的数据送至单片机处理后,由ZigBee无线传输至服务器以对粮库环境进行监控。并且对于本系统的抗干扰问题做了分析,给出了相应的措施。
Aiming at the disadvantages in granary monitoring system at present, such as wiring difficulty, poor extensibility and high cost, a granary monitoring system design scheme is presented, which can monitor O2. CO2, temperature, humidity and alarm when exceeding limits. This network adopts the distributed network structure, as well as collects and transfers the O2. CO2 temperature and humidity data by sensor network nodes. It also can transmit the collected data to single- chip. Then via ZigBee, it transfers the results to the server wirelessly where the temperature, humidity and pest number in grain depot can be monitored. And then, the problem of anti-jamming about this system is analyzed and the methods are g,ven.
