【正文】 68HC16, C51 MCU and so on. Data transmission unit can be selected from lowpower, shortrange wireless munication modules, but considering the antitheft and natural damage, the system chooses the larger power, transmission distance of SA68D21DL, farmers can be placed in the office or home, the main controller. Figure 2 depicts the position of the node, in which the direction of the arrow indicates that the data flow direction in the node. The main control system In this system, the control work and Inter hosts as the connection between the wireless sensor work protocol conversion gateway. The hardware used Zhiyuan Electronics Mini ARM embedded puter modules. MiniISA series acquisition board structure using smart card, that card on the builtin on the board onboard I / O ports control, to achieve I / O data buffer, thereby reducing the interface to the host board for Mini ISA dependence, saving the host data processing time, to ensure MiniISA system more efficient operation. MCU board can also collect data or output data for further processing. System schematic shown in Figure 3. Design of the remote control system is mainly GPRS munication system, GPRS and Inter work access system, the monitoring center consolefriendly interface display control system. This part of the hardware can be applied to existing mobile telemunications panies and Inter resources, software and professional capabilities to consider the cost of independent development, the proposed application of the existing remote software, such as Ball Remote Control software, remote monitoring equipment Co., Ltd. in Hunan Province The RC2021 remote control software visualization system. Concluding Remarks This paper reviews the nodes of wireless sensor works, characteristics, and current applications in agriculture, researchbased embedded systems, intelligent wide are a of farmland out of the water supply system, water is detected field information to continue through the automatic control Electric water pump to start, and realized the remote GPRS munications, PC, to learn through the health system and over which it controlled, automatic acquisition of soil information to determine whether to activate the pump from the line for the farm water supply, which is in line with China39。s rural areasbasic national conditions. The system is simple, click on the system transformation, can be designed courtyard automatic water supply systems, automatic water supply system and a garden greenhouse automatic water supply system, so the scalability of the system is better, relatively broad prospects. Today39。s wireless sensor work as a new hotspot in the field of information, involving interdisciplinary. With the reduced cost sensors and related solutions to continuous optimization problems, such as power consumption and data fusion algorithm is more small, node localization algorithm in continuous improvement, and more advanced wireless RF module, wireless sensor works will be more in agriculture wide range of applications.
