[Abstract]:The society has entered the information age, modern agriculture is synchronized with the information technology. Modern agriculture closely combines agricultural technology, computer technology, network communication technology and other information technology. Fine agriculture has become a hot area of agricultural sustainable development research, and is widely used in agricultural production. At the same time, research and development of fine agricultural technology suitable for the national conditions of our country. To improve environmental quality, enhance consumer confidence in food safety, and vigorously develop pollution-free agricultural products. Agricultural production information collection is the basis of the implementation of fine agriculture, but also the bottleneck of the development of fine agriculture. The feasible scheme of agricultural product production information collection is studied and analyzed. Aiming at the problem of data collection and transmission in the production process of pollution-free agricultural products in our country, combined with the more popular embedded technology at the present stage, high and new technologies such as computer technology and network technology are applied in the field of agriculture. Based on ARM and WinCE, an embedded information collection system for pollution-free agricultural products is developed. This system adopts the hardware platform based on ARM, guided by the modular design idea, selects the YLE2440 embedded development board of Yulong Company as the foundation, and expands the card reader module according to the system needs. Ethernet module and power supporting module have completed the construction of the hardware platform of the system. The platform structure is reasonable, the function is relatively complete, and the expansibility is strong. In this paper, the software platform based on WinCE is adopted, and the software architecture of B / S is used to complete the implementation of the system. Firstly, it is based on the requirements of the construction of the WinCE software platform. The WinCE kernel is successfully customized according to the needs of application development. Secondly, on the basis of analyzing the structure of WinCE device driver, the wireless network card driver is added to the WinCE kernel. Secondly, the application programs such as credit card authentication and touch screen calibration are successfully written using the application development tool EVC, and the software construction of the browser is completed. Finally, according to the requirements of application development, a wireless local area network (WLAN) was established for the production information collection system of pollution-free agricultural products, and the Web server based on B / S structure was successfully built. Web pages and database data stored in the server, the database contains the production of agricultural products related information, the client sent requests, the server received, parsing requests. The requested data is downloaded to the client and displayed by the browser. With this system, the production base staff can input and upload the agricultural product information to the backstage database through the network. The experiment shows that the system has small volume, low cost, high stability and real-time. Can be widely used in facilities agriculture, farmland, agricultural parks and other places, can provide crop planting, fertilization, irrigation, harvesting and other information collection functions, to achieve information and data exchange with the server; And for agricultural decision-making, production management to provide effective data support, improve the scientific macro decision-making, has a high market value and application prospects. Moreover, the system has been verified in practice, the most important is. The system is helpful to promote the application of information technology in the field of agriculture in China, promote the development of fine agricultural technology in China, and accelerate the process of agricultural modernization in China.
