基于无线数传技术的农田灌溉机井集中监控系统

The Distributed Control System Based on the Wireless Connection Module on Water Pump

对农田灌溉机井集中监控系统进行了研究,介绍了系统的硬件组成及其工作原理,给出了硬件组成框图。该方案采用分布式结构,上位机负责系统监控和管理,下位机进行数据采集和命令执行。硬件上利用无线数字通信模块为核心,实现上位机和下位机之间数据的无线传输。软件上采用面向对象的编程语言作为开发工具,并就系统通信程序的设计思路进行了介绍。同时,对系统的应用前景进行了简要分析。

This article analyses the distributed control system on water pump in agriculture. It introduces the hardware composition and its work principle. And it also gives the hardware composition diagram. This plan uses the distributed control structure. On the position machines responsible is m.ainly of the system＇s monitoring and management. The Lower position machine＇s duty is data acquisition and order execution. This system makes use of the wireless connection module as the core hardware which realizes the data wireless transmission between the two position machines. It adopts the object-oriented programming language as the develop tool. The paper introduces the design principle of the communication program. It also analyzes the application prospect in briefly at the end.
