Study Of Rapeseed Field Environmental Information Collection Key Technology Based On WSN

The environmental information of crop growth is one of the important information of crop growth process. Via analyzing the connection between environmental information and crop growth&output, we can achieve precisely in finding out the factors that affect crop growth, further we are able to control and improve the quality and output of crops accordingly. Therefore, it is pretty valuable to research and figure out how to collect, transmit and analyze the environmental information of crop growth.At present, in the field of agriculture, the quantity of automatic applications of information collection is limited, and there are some problems among limited existing applications, such as:expensive prices, low transmission stability, inconvenient operation, etc. Moreover, most of the current researches focus on agricultural facilities design, but lack of applications on large farmland. In order to solve these problems, this paper presents an environmental information collection system of rape field, using WSN as data transmission method, specialized in studying the selection of sensor solutions, the improvement of routing protocol and the design and R&D of host computer platform. Its main tasks are as follows:1) Analyzed the domestic and foreign present research situation and the actual situation in our country, and developed a questionnaire survey system by ourselves, established the system structure and the key technical problems need to be solved based on a great quantity of investigation.2) Combine with the feature of WSN’s routing transmission and this paper’s needs, put forward a improved routing algorithm----F-ZRP. We add fault-tolerant mechanism in ZRP, so the F-ZRP can improve the reliability of the transmission route and reduce the WSN network overhead.3) Devised and developed a software system based on the need of user and the development trend of the information technology, the system has many functions, such as data receive、data display、formula fertilization model、production model、monitoring and warning etc. and the system can used in PC or mobile platform, so user can login in any time.
