基于組態(tài)軟件的水箱液位控制

摘要：利用組態(tài)王監(jiān)控軟件設(shè)計(jì)了一個(gè)水箱液位實(shí)時(shí)控制系統(tǒng)。首先介紹了控制系統(tǒng)的硬件組成、采用的控制方案。然后，詳細(xì)描述了利用組態(tài)王進(jìn)行監(jiān)控畫(huà)面設(shè)計(jì)、水箱液位PID控制程序設(shè)計(jì)、歷史數(shù)據(jù)存儲(chǔ)等設(shè)計(jì)過(guò)程。最后，詳細(xì)介紹了系統(tǒng)的實(shí)驗(yàn)步驟、調(diào)試過(guò)程、以及畢業(yè)設(shè)計(jì)過(guò)程中遇到的問(wèn)題和解決辦法。實(shí)踐結(jié)果表明，設(shè)計(jì)的水箱液位控制系統(tǒng)能夠?qū)崿F(xiàn)水箱液位的自動(dòng)控制，控制效果好，運(yùn)行穩(wěn)定，操作方便。

Water tank fluid position control system design based on Kingview

Abstract：Make use of a set of Kingview the supervision software designed a water tank liquid solid control system.The hardware that introduced control system first constitutes, adoption of control project.Then, described to make use of a set of Tai king to carry on supervising and controling an appearance design, water tank liquid in detail PID control program design, history data saving etc. design process.End, introduced the experiment step of system, adjust to try process in detail, and the graduation designs to meet in the process of problem and solution.Practice result enunciation, design of water tank liquid control system to carry out a water tank liquid the automatic control of, control effective, circulate a stability, operate convenience.

Key words：Water tank liquid;The calculate way of PID;Supervise and control system;Kingview.
