摘要
针对当前农业发展的需要,通过采用ZigBee与串口通信技术将温室信息实时传输到监测系统,使种植者可以及时了解大棚环境,并根据接收到的数据对大棚环境进行控制。以VB.NET开发上位机程序,用传感器接收温湿度数据,并通过ZigBee无线通信模块将信息通过串口传送给上位机,再由上位机监测软件完成数据的存储。对大棚中每一个节点的温湿度进行实时显示,当超出系统预先设定的温湿度期望值区间时,发出报警声音。实验说明,基于ZigBee的无线传感网络监测系统有着低功耗、小体积、使用简单方便等特点,更加适合现代化的农业发展。
Aiming at the requirement of agricultural development, the ZigBee and serial port communication technology are used to transmit the data from greenhouse to the monitoring system. With this, the growers can timely know the greenhouse environment and control the greenhouse environment according to the received data. The upper computer program is developed with VB.NET. The temperature and humidity data is received by the sensor and transmitted to the upper computer through the serial port by the ZigBee wireless communication module, and then the data is stored by the monitoring software of the upper computer and the temperature and humidity data is real-time displayed. When the data is over the threshold value, the system will give an alarm. The experiment result shows that the wireless sensor network monitoring system based on ZigBee has the characteristics of low power consumption, small volume, simple and convenient, and more suitable for the development of modern agriculture.
