摘要
针对经济林生产管理的需要,开发了经济林信息监控系统。该系统基于ZigBee无线网络,以ST公司研发的低功耗ARM9微处理器STR911FAM42模块为核心,整个无线传感器网络由无线环境监测子节点和无线环境监测网关节点组成。网络子节点分布于经济林的各个测量点,负责环境信息采集、预处理和无线传输等工作,网络网关节点负责处理全部子节点采集的环境信息。无线信息监控系统实现了对经济林生长环境因子(环境温湿度、土壤温湿度、光照、雨量、土壤酸碱度)的实时监测。实验表明,该系统运行可靠,在数据精确采集和实时可靠传输方面达到了设计要求,能够为经济林提供实时可靠准确的环境信息监测服务。
For meeting the needs of nonwood forest production management,a new information monitoring system for nonwood forest is developed based on ZigBee.Low-power ARM9 microprocessor core module STR911FAM42 made by ST company is used as the main unit.The whole system is comprised of several wireless environment monitoring subsidiary nodes and network gateway node.The wireless subsidiary nodes distributed over the whole region of nonwood forest are responsible for environmental information collection,pre-processing and wireless transmission.Network gateway node is used to collect data from all subsidiary nodes.The system realizes real-time monitoring for nonwood forest environmental factors（ambient temperature and humidity,soil temperature and humidity,light,rainfall,soil pH）.The test result showes that the working performance of the system is quite stable and can reach the design requirements in precise data acquisition and reliable remote transmission.The system can provide reliable and accurate real-time monitoring of environmental information service for nonwood forest.
