摘　　要：针对农林环境中复杂的实际情况,设计一种基于物联网的农林环境长期监测系统。系统采用基于CC2530芯片的Zigbee无线传感器网络节点、电源控制硬件电路和基于ARM11的现场服务器,利用太阳能电池供能,通过对IEEE802.15.4和IEEE802.11协议进行转换,将数据通过无线网桥远程传输给管理服务器。该系统能够监测农林环境中的温度、湿度、光照强度、pH值等,可长期对农林环境因素进行采集、监测和分析。Aiming at the complex actual situation of agricultural environment, this article puts forward an implementation plan of long- term monitoring system of agricultural environment based on Internet of Things （IOT）. Zigbee Wireless Sensor Network （WSN） node based on CC2530 chip, hardware circuit of power supply management and site server based on ARM11 are designed. This design is powered by solar battery and conducts protocol conversion between IEEE802.15.4 and IEEE 802.11 to transport the data to the management server through the wireless bridge. This system can monitor the temperature, humidity, ligl^t intensity, PH value, CO2 concentration, CO~ con- centration and 02 concentration of agricultural environment, which can also collect, monitor and analyze agricultural environmental fac- tors for long term.
