摘 要:混凝土攪拌站是隨著水泥的誕生而產(chǎn)生和發(fā)展的。它是建筑、橋梁、道路、大壩等工程施工中的必備設(shè)備，隨著我國經(jīng)濟(jì)建設(shè)的高速發(fā)展，綜合國力不斷增強(qiáng)，國家對基礎(chǔ)設(shè)施建設(shè)的投資力度加大，拉動了城市商品混凝土的高速發(fā)展，同時，使混凝土攪拌站有了較大的發(fā)展空間。最初攪拌站僅以手動的形式出現(xiàn)，后來過渡到繼電器控制、單片機(jī)控制、PLC控制等。隨著基礎(chǔ)設(shè)施建設(shè)大規(guī)模的開展，產(chǎn)生了很大的商品混凝土市場，攪拌站的需求越來越大，計量要求越來越高，于是出現(xiàn)了各種不同形式帶有計量裝置的攪拌站。 本文采用了三菱PLC對混凝土攪拌站進(jìn)行控制并采用組態(tài)王進(jìn)行模擬，主要介紹了混凝土攪拌站的現(xiàn)狀及其研究目的和意義，完成部分硬件的選擇，系統(tǒng)的設(shè)計方案和PLC的I/O分配，控制程序的編寫并對程序進(jìn)行解釋，完成組態(tài)模擬工程。 關(guān)鍵字：混凝土攪拌站；PLC；自動控制；I/O分配
ABSTRACT:Concrete batching plant is produced with the birth and development of cement. It is a necessary equipment for engineering construction, bridges, roads, dams and other construction, with the high-speed development of China economy, comprehensive national strength, the state's infrastructure construction investment increased, pulling the rapid development of city commercial concrete, at the same time, the concrete mixing stations have larger development space. The initial mixing station appear only in a manual form, then the transition to the relay control, microcomputer control, PLC control, and so on with the development of large-scale infrastructure construction, the commercial concrete mixing station big market, the demand is more and more big, metering requirements more and more high, so there are different forms with metering device mixing station. This paper adopts the Mitsubishi PLC on concrete mixing station control and using King view simulation, mainly introduces concrete mixing station status and the purpose and significance of the study, completed the hardware selection, design and PLC system control program is written and the procedures for interpretation, to complete the configuration simulation engineering. Key words: concrete batching plant; PLC; automatic control; I/O distribution |
