滴灌施肥裝置控制系統(tǒng)設(shè)計[包括組態(tài)王程序]

[摘要]隨著生產(chǎn)和科技的發(fā)展，針對滴灌施肥控制系統(tǒng)中的實際情況，本設(shè)計采用基于軟件King View 6.53的監(jiān)控系統(tǒng)，結(jié)合傳感器技術(shù)、PLC技術(shù)和微機監(jiān)測技術(shù)構(gòu)建計算機監(jiān)控系統(tǒng)。隨著現(xiàn)代控制技術(shù)的發(fā)展，本設(shè)計以PC機作為上位機，實時監(jiān)控液位、流量、壓力及各種肥的濃度等被控量的信息狀態(tài)，不但可以使用戶實時了解被控量，而且可以很方便的下達控制指令。在滴灌施肥過程中通過上位PC機的實時監(jiān)控程序?qū)κ┓蔬^程中的狀態(tài)參數(shù)（如EC/PH值、流量、液位、實時曲線等）進行實時顯示，對數(shù)據(jù)進行保存和處理，并且能夠按照用戶設(shè)置的施肥程序?qū)崟r自動的控制施肥液濃度、施肥量和施肥時間等參數(shù)，執(zhí)行精確的施肥過程，提高農(nóng)產(chǎn)品的產(chǎn)量和品質(zhì)。

　　　本設(shè)計使用的King View 6.53軟件以及其所帶的控件構(gòu)成的系統(tǒng)能夠完成數(shù)據(jù)的采集，監(jiān)測，實時控制等功能，同時完成數(shù)據(jù)保存、查看以及報警功能等等，實現(xiàn)趨勢分析、顯示。本設(shè)計完全能實現(xiàn)滴灌施肥控制系統(tǒng)中監(jiān)測與控制，能夠滿足用戶的需求。

Abstract: with the development of production and technology, in view of the actual situation in the control system of drip fertigation, the design of the monitoring system software based on King View 6.53, construction of computer monitoring system combined with the sensor technology, PLC technology and computer monitoring technology. With the development of modern control technology, the design of the PC machine as the position machine, real-time monitoring of liquid level, flow, pressure and concentration of various fertilizer amount charged state information, not only can the user real-time understanding of the controlled quantity, but also can make control instruction is very convenient. Through the upper PC real-time monitoring program of state parameters in the process of fertilization in drip irrigation and fertilization process (such as EC/ pH, flow, level, real-time curve) for real-time display, preservation and processing of the data, and the parameters can be set by the user application program of real-time automatic control of fertilizer solution concentration, amount of fertilizer and fertilization time, perform fertilization process accurately, improve the yield and quality of farm products.

　　　System design using King View 6.53 software and control the belt can complete the data collection, monitoring, real-time control functions, at the same time, data save, view and alarm functions and so on, trend analysis, display. This design can fully and control to realize monitoring of drip fertigation control system, to meet the needs of users.

Keywords: programmable controller automatic control configuration software of drip fertigation
