The Design of a Grassland Environmental Monitoring System Based on ZigBee Wireless Sensor Network

针对目前草原退化现象严重、载畜能力下降等问题,提出一种基于ZigBee无线传感器网络的草原环境监测系统方案。系统由草原无线监测网络和远程PC机二部分组成,实现对影响草原牧草生长状况的空气温湿度、光照强度和降雨量等环境信息的实时、远程监测。采用以CC2530无线微处理器芯片为核心,设计开发了协调器节点和传感器节点的硬件与软件流程。初步试验表明,具有构建简单、稳定可靠、准确度高等优点,能较好地满足草原环境监测的应用需求。

In view of serious grassland degradation and decreasing livestock-carrying capacity, this paper presents a grassland environmental monitoring system based on ZigBee wireless sensor network. The system, consisting of grassland wireless monitoring network and remote PC, realizes remote real-time supervision over information about environmental factors affecting herbage growth such as air temperature and humidity, light intensity and precipitation. Hardware and software processes are developed for the coordinator node and sensor node by using CC2530 wireless microprocessor chip as the core. Preliminary tests indicate that the system with its simple construction, good stability and reliability and high accuracy can meet the application requirements on grassland environmental monitoring.
