Research And Application Of Wireless Sensor Technology In Precision Agriculture

As the waste of resources and environmental degradation in the process of agricultural production is serious, there is growing concern pattern of agricultural development. Precision agriculture is the development trend of modem agriculture is a sustainable and ecological agricultural production patterns, and making full use of its theory and technologies, is an effective way to alleviate the contradictories between agriculture and resources and ecological environment. But the basic theory and techniques of research in precision agriculture needs to be improved, which restricts its application in the country. In this paper, according to the requirements of project construction, designing the platform which combines two technologies including embedded microcontroller and configuration monitoring software in engineering equipment, in to accurately manage and statistics several factors influence on agro-ecological park. To achieve the goal, mainly to complete the following:To achieve the objectives, the design was completed for the following:(1) There is a certain complexity in signal transmission between the wireless sensor network with each other, in order to save energy and maintain the stability of the system, using the theory of rational dynamic algorithm can achieve accurate and efficient transmission of signals, and maintent the long-term stable operation of the system.(2) This paper mainly introduces the embedded devices as the field processing module, which comprises two boards,such as a core board for the STM32processor and a wireless sensor network board of CC2530, and the KingView6.55configuration software as the technological platform of control center, then makes their application in the technology system of precision agriculture of the ecological park. Hardware design includes two parts, one part is data information processing of core board, including the switch trigger, I/V and D/A conversion of4～20ma as kernel functions, and displaying LCD, setting keyboard and selecting dial switch as auxiliary functions, the other part is the wireless transmission board. Besides The system software engineering of core board integrates the multi-task and real-time management operating system of μC/OS-Ⅱ, which can improves the efficient work and stability of system operation. KingView6.55by the control center monitoring configuration software, which seamlessly communicate with the embedded devices can be used to collect and send data information under the frame agreement, at the same time, other man-machine interface control in the software system can be used in real-time realistic picture control, historical statistical analysis and so on, which can improves the comprehensive ability of analysis to the whole system processing.Through simulation test, the results verified the reliability and real-time of system design, which can meet the requirement of conditions in engineering application, at the same time the prospect of work put forward some constructive suggestions.
