      abstract = {Against the demand of intelligent greenhouse construction  of facility agriculture, greenhouse environment monitoring  system is developed. The system contains three-layer  architecture: sensor network layer at the bottom, data  transmission convergence layer in the middle and monitoring  application layer on the top, which is different from  design idea of the existing system architecture. The bottom  layer uses ZigBee wireless communication technology to  construct wireless sensor network, and node type contains  coordinator, router and acquisition terminal. Acquisition  terminal is distributed in each greenhouse to collect data  and play the role of wireless transmission, and router  plays the function of data forwarding as the bridge of  acquisition terminal and coordinator. Middle layer is  composed of monitoring software developed by LabVIEW  software of NI Company and coordinator, which is used to  gather data from the bottom layer. The top layer is  comprehensive monitoring platform developed by Java  language, which is used to gather greenhouse data of all  plantation bases in one region, thereby providing  comprehensive information service for government,  enterprise and farmer. Greenhouse environment monitoring  system realizes data collection and sharing of greenhouse  environment information（air temperature, air humidity,  light intensity and carbon dioxide concentration）. Via test  verification, the system’s operation is stable, with  certain application value. },
