基于GPRS和ZigBee的精准农业模式

The Research on Precision Agriculture Based on GPRS and ZigBee

针对传统农业的局限性,探讨了传统农业生产模式转变为以信息网络为中心的精准农业生产模式的方法.采用GPRS和ZigBee的无线传感器网络技术,提出了精准农业模式中的无线组网实现方案,给出了相应的硬件实现方法和软件流程.该方法通过ZigBee无线传感器模块,可采集土壤湿度、氮浓度、降水量、温度和气压等信息,并用GPRS发送信息至远程监控中心.监控中心根据信息及时发出控制命令,使农业管理部门或农户及时采取相应措施,从而降低成本,有效地提高农作物产量.

For the limitations of traditional agriculture, this paper discusses how the traditional model for agricultural production is transferred into the model of precision agriculture with the center of information network. A wireless building-network project is presented for precision agriculture model, and the hardware realization and software flows are given too. By means of ZigBee wireless sensor module, the method can get together much information on soil humidity, nitrogen concentration, precipitation, temperature, the atmosphere humidity and pressure and so on. Then such information is delivered to the remote control center through GPRS. According to received information, the control center sends out the control command in time so that agricultural manage departments or farmers take relative measures. Therefore, costs can be reduced, and crop production can be increased.
