摘要
根据现代农田合理灌溉的需求,设计了一种基于ZigBee技术的农田土壤温湿度监测系统,该系统由传感器节点、协调器节点和PC机组成。采用低功耗的CC2530芯片为核心,设计开发了协调器节点、传感器节点的硬件电路和软件流程。传感器节点增加了功放CC2591,实现农田无线网络土壤信息的远距离传输。试验表明,系统能够实时显示土壤温度及传感器节点网络地址,并在无障碍情况下,网络通信距离可达1.8km。该系统具有距离远、成本低、功耗低等特点,满足设计要求。
According to the demand of reasonable farmland irrigation, a kind of farmland soil moisture and temperature monitoring system based on ZigBee technology is designed in this paper. The system is composed of sensor nodes, the coordinator node and PC machine. The low-power CC2530 chip is taken as the core, the hardware circuits and software process of the coordinator node and sensor nodes are designed. The power amplifier CC2591 is added to sensor nodes to realize the long distance transmission of farmland soil information in wireless network. The experiment result shows that the system can real-time display the soil temperature and the sensor node network address, and the network communication distance can reach up to 1.8kin under the barrier free condition. The system has the advantages of far distance, low cost and low power consumption, can meet the design demand.
