摘要
为实现多点土壤水分传感器和现地监测终端的多点无线连接,在介绍MP-406土壤水分传感器结构原理的基础上,分析了将增强型ZigBee技术通过微功耗PIC微处理器桥接整合到MP-406土壤水分传感器中,实现土壤水分传感器的无线网络化的具体设计。利用无线网络化技术能组成实用的土壤墒情在线监测系统,且组网简单灵活。
For the sake of realizing multipoint wireless connection between soil moisture sensors and in-situ monitoring control unit, a new kind of wireless connection is developed. By describing structure and principle of MP-406 type soil moisture sensor, the paper gives an analysis about detailed design of wireless networking for soil moisture sensors by bridging and integrating ZigBee technology into the soil moisture sensor through PIC micro-processor. Application of wireless networking technology can make up a practical on-line monitoring system for soil moisture with characteristics of simple and flexible networking.
