【摘要】：動(dòng)態(tài)液體定量灌裝稱重設(shè)備是集結(jié)了自動(dòng)控制、電子秤重、傳感器等技術(shù)的自動(dòng)化裝備。此種設(shè)備的出現(xiàn),很好的融入到了社會(huì)生產(chǎn)生活中,應(yīng)用在各行各業(yè)中。在此基礎(chǔ)上決定選用STM32芯片控制技術(shù)研制一套基于定量稱重灌裝系統(tǒng)。本研究課題是企業(yè)技術(shù)開發(fā)項(xiàng)目,旨在研制出一套動(dòng)態(tài)液體定量自動(dòng)稱重定量灌裝系統(tǒng)。在企業(yè)方提出的設(shè)備實(shí)現(xiàn)要求的基礎(chǔ)上,研究了動(dòng)態(tài)液體定量灌裝相關(guān)知識(shí)。本論文對(duì)STM32系列芯片進(jìn)行了深入研究,確定其為灌裝系統(tǒng)主控芯片。在充分分析了項(xiàng)目實(shí)現(xiàn)目的的基礎(chǔ)下,圍繞項(xiàng)目進(jìn)行控制系統(tǒng)的整體設(shè)計(jì),分模塊的完成各部分電路設(shè)計(jì),最后搭建起實(shí)物測試系統(tǒng)性能。在實(shí)物測試中,不斷調(diào)整各參數(shù),軟件程序上不斷修改,對(duì)灌裝精度和效率進(jìn)行改進(jìn)。其中,灌裝采用的是不同于現(xiàn)有的調(diào)節(jié)閥,而是比例調(diào)節(jié)的4421閥門,相比于8421比例閥門,實(shí)際使用中4421閥門更好實(shí)現(xiàn)了灌裝重量的快速精確控制。經(jīng)過對(duì)PID控制和模糊控制進(jìn)行模型仿真研究比較后,最終決定采用一種基于比例調(diào)節(jié)的定量灌裝系統(tǒng)。比例調(diào)節(jié)是一種基于模糊思想上的控制方法,采用比例閥門直接對(duì)灌裝過程進(jìn)行控制,模型仿真和實(shí)物都取得了滿意的效果。
[Abstract]:Dynamic liquid quantitative filling and weighing equipment is an automatic equipment which integrates automatic control, electronic weigher, sensor and so on. The emergence of this equipment, a good integration into social production and life, applied in various industries. On this basis, it is decided to choose STM32 chip control technology to develop a filling system based on quantitative weighing. This research project is an enterprise technology development project, aimed at developing a dynamic liquid quantitative automatic weighing and filling system. On the basis of the equipment realization requirements of the enterprise, the dynamic liquid quantitative filling related knowledge is studied. In this paper, STM 32 series chips are studied, and it is determined that STM 32 chip is the main control chip of filling system. Based on the analysis of the purpose of the project, the overall design of the control system is carried out around the project, and the circuit design of each part is completed. Finally, the performance of the physical test system is built. In the physical testing, the parameters are constantly adjusted, the software program is constantly modified, and the filling accuracy and efficiency are improved. The filling valve is different from the existing control valve, but the proportional control valve is 4421. Compared with the 8421 proportional valve, the 4421 valve in practical use is better to realize the rapid and accurate control of filling weight. After the simulation of pid control and fuzzy control, a quantitative filling system based on proportional adjustment was finally adopted. Proportional adjustment is a control method based on fuzzy idea. The proportional valve is used to control the filling process directly. The model simulation and the material object have achieved satisfactory results.
