[Abstract]:With the development of sensor technology, communication technology and computer technology, wireless sensor network and multi-sensor data fusion has become a hot spot in the field of scientific research, and has been widely used in many fields such as agriculture. In greenhouse agricultural production process, a variety of environmental factors affect the growth of crops. According to the need of greenhouse production, this paper designs the greenhouse monitoring system of wireless sensor network, and makes the research of data fusion algorithm according to the characteristics of collected data. The main contents of this paper are as follows: 1) the design scheme of the greenhouse monitoring system for wireless sensor networks is proposed, and the overall architecture of the system is built. According to the demand of node design, the design of sensor node data transmission network is completed by using ZIGBEE technology through the analysis and comparison of several commonly used short-range wireless communication technologies. According to the needs of greenhouse, 3G network is used to transmit data from convergence node to server and monitor video transmission. 2) in order to realize information sharing of agricultural resources and remote monitoring of greenhouse, a remote integrated service network of greenhouse based on B / S structure is designed and developed. Struts architecture and SQL Server database are adopted. The pagination display of historical data is completed by JSTL, and the display of data graph is realized by FLOT. Real-time video surveillance uses embedded ActiveX control method, and designs the control module of camera cloud head at the same time. 3) the necessity of data fusion is expounded. An improved Kalman filter algorithm is proposed for greenhouse monitoring. The algorithm function is called from the web page to fuse the extracted data, and the processed results are stored in the database and sent to the page for display. 4) the actual operation of the system is tested and displayed. Through the remote access of the browser, the environment parameters can be queried online and displayed in the form of charts, the real-time video monitoring can be completed, and the camera can be adjusted remotely.
