农产品远程价格信息采集和发布系统的研究

利用TC35与低功耗单片机结合设计便携式手持数据采集终端,采用手持信息采集终端收集信息,通过GSM方式传送到数据中心,数据中心负责处理和发布信息,实现了农产品远程价格信息的采集和发布,用户可通过上网或手机短信进行价格查询。系统实时性好,可靠性高,克服了以往信息采集发布的缺点,能够有效的进行农产品价格信息方面的信息传递工作及数据统计。详细阐述了手机模块TC35中SMS功能的工作原理、便携式手持终端的硬件设计与软件实现。经示范应用,系统达到了设计目标。

Research on Remote Price Information Acquisition and Publication System of farm Produce

This thesis designs a new kind of information-collecting system based on the combination of the single-chip microcomputer and the Siemens mobile module TC35. It acquires information by handheld information acquisition terminal, the terminal sends the information to data center in the form of short message, data center processes the information and publishes it. Users can inquire about the price information on internet and also through short message. The system has good real time performance and is reliable, overcoming former disadvantages on information acquiring and publishing, the system works efficiently on information transfer and data statistics. The function principle of the SMS is introduced and the design of the hardware and the software are also discussed in details. Demonstration on applying the system shows that it achieved its desired objective.
