Abstract:The current main pests monitoring using artificial experience, or through relevant data such as expert analysis method, the labor intensity big, non real-time and low efficiency of defects. Judging was designed and implemented a WEB based forest pests visual monitoring system, gives the WEB server, CC2430 processor module, data acquisition module, communication interface and the database of hardware principle, software of the system function implementation steps are given, the software design is divided into two kinds of server software and client software module, the visual positioning method of forest pest area spatial location parameter, for forest insect pest area in the standard coordinates domain coordinates, realize accurate monitor and judge the degree of forest pests. System test result shows that this system can carry on the accurate positioning and to the extent of forest pests, and has high accuracy and efficiency.
