【摘要】：当今社会已经进入信息化时代,现代农业是与信息化同步的农业。现代农业将农业科技、计算机技术、网络通讯技术等信息技术紧密结合,朝着精细农业的方向发展。精细农业已经成为农业可持续发展研究的热门领域,并且被广泛应用于农业生产。同时,研究和发展适合我国国情的精细农业技术,有利于改善环境质量,增强消费者对食品安全信心,大力发展无公害农产品。农产品生产信息的采集是实施精细农业的基础,也是发展精细农业的瓶颈。为此,本课题根据国内外农产品信息采集领域的研究现状,研究分析了农产品生产信息采集的可行方案;针对我国无公害农产品生产过程中数据采集传输问题,结合现阶段较为流行的嵌入式技术,将计算机技术、网络技术等高新技术应用于农业领域,研究开发了基于ARM和WinCE的嵌入式无公害农产品生产信息采集系统。本文系统采用基于ARM的硬件平台,以模块化设计思想为指导,选用优龙公司的YLE2440嵌入式开发板为基础,根据系统需要扩展了读卡器模块、以太网模块、以及电源支持模块等,完成了系统硬件平台构建。平台结构合理,功能较完备,可扩充性强。本文系统采用基于WinCE的软件平台,以B/S软件架构完成系统应用的实现。首先基于WinCE软件平台的构建要求,依据应用开发的需要成功定制了WinCE内核;其次在分析WinCE设备驱动程序结构的基础上,添加无线网卡驱动程序到WinCE内核;接着利用应用程序开发工具EVC,成功编写了刷卡认证、触摸屏校准等应用程序,完成了浏览器端的软件构建;最后,根据应用开发的需求,为无公害农产品生产信息采集系统建立了无线局域网,成功搭建了基于B/S结构的Web服务器,网页和数据库数据存放在服务器端,数据库中包含了农产品生产的相关信息,客户端发送请求,服务器端接收、解析请求,并将请求的数据下载到客户端由浏览器显示。使用该系统,生产基地工作人员能够将农产品信息录入并通过网络上传、保存到后台数据库中。实验证明,该系统具有体积小、成本低、高稳定性和实时性,可广泛应用于设施农业、农田、农业园区等场所,可以提供农作物种植、施肥、灌溉、收获等信息采集功能,实现了与服务器端进行信息数据交互;而且为农业决策、生产管理提供有效数据支持,提高宏观决策的科学性,有很高的市场价值和推广应用前景。并且,该系统已经得到了实际验证。最重要的是,该系统有助于推动信息技术在我国农业领域中的应用,促进我国精细农业技术的发展,从而加速我国农业现代化的进程。
[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.
