Abstract
This thesis is a design process of the automatic control system of the irrigation pumping station based on PLC. The application of this automatic pumping irrigation system in agriculture can solve many problems. This design mainly consist of SIEMENS model PLC controller, Circuit breaker, Contactor, Switch appliance, and SIEMENS Master Miscro 430 converter for variable speed operating device. The overall system can be divided into six part, including the main controller PLC part, detection part, operation interface, monitoring system, alarm system, protection system. The programming software of SIEMENS S7-300 is STEP 7, and the monitoring system for the construction of Kingview. In the monitoring system, the operating parameters of the system , the running trend chart and the fault alarming display can be displayed in the monitoring interface. The design of the automatic control system with the programmable logic controller PLC of pumping station can not only be reasonable but efficient to complete the irrigation. With the well reliability , the low energy consumption , it is the ideal control system. Keyword: PLC; Pumping station; Automatic control system; Monitoring system.

摘要
小型灌溉抽水泵站 PLC 自动控制系统这种自动抽水灌溉系统在农业上的应用可以 解决很多问题。本设计主要以西门子 PLC 为主控制器，西门子 Miscro Master 430 变频 器为变频运行器件，结合空气断路器，接触器，开关电器，中间继电器等组成硬件控制 系统。整体上可分为主控制器 PLC 部分、检测部分、操作界面、监控系统、报警系统、 保护系统。西门子 S7-300 的编程软件是 STEP 7，监控系统用组态王构建。在监控系统 中能实时显示系统的运行参数和运行趋势图及故障报警显示。用可编程逻辑控制器 PLC 设计抽水泵站的自动控制系统不仅能合理、高效的完成灌溉，且可靠性高、耗能低，是 最理想的控制系统。 关键词：S7-300 PLC；抽水泵站；自动控制系统；监控系统
