基于Zigbee的无线粮情监控网络中测量节点的设计

Design of measuring node in wireless grain condition monitoring net based on Zigbee

针对传统有线粮情监控系统存在的缺陷,提出"平面分离、上下贯通"的无线粮情监控网络的设计思路,实现了设计目标的基本单元测量杆的功能结构,规划了基于Zigbee的无线粮仓温湿度监控网络。根据节能需求将无线监控网络中的节点分为测量节点和路由节点,完成了测量节点的接口电路和主程序设计,并对测量节点中的关键技术进行了阐述。

In order to tackle the problems exist in the traditional wired grain condition monitoring system, an idea of separate in the same surface and pipe in the vertical line is put forward. The structure of measuring pole, which is the basic unit of design, is proposed. The frame of wireless monitoring system is laid out. The n^des in the wireless monitoring net are divided into two groups, measuring nodes and bypass nodes, according to the energy-saving needs. The interface circuit and main program of measuring nodes is finished. And the key technology is elaborated.
