摘要
隨著當(dāng)今世界科學(xué)技術(shù)的突飛猛進(jìn)，電氣自動(dòng)化技術(shù)也日趨完善和優(yōu)化，其中可編程控制器越來越廣泛地應(yīng)用在生產(chǎn)中，極大地提高了人類生活和生產(chǎn)的自動(dòng)化程度，在社會(huì)的發(fā)展和人類的進(jìn)步中起到了積極的作用。改革開放以來，我國(guó)經(jīng)濟(jì)建設(shè)高速發(fā)展，綜合國(guó)力不斷增強(qiáng)，國(guó)家對(duì)基礎(chǔ)設(shè)施建設(shè)的投資力度加大，拉動(dòng)了城市預(yù)拌商品混凝土的高速發(fā)展，同時(shí)，使混凝土攪拌站有了較大的發(fā)展空間。
隨著許多大型的基礎(chǔ)工程及建筑工程相繼開工，建設(shè)優(yōu)質(zhì)的工程需要高品質(zhì)的混凝土，而且隨著人們環(huán)保意識(shí)得加強(qiáng)，為了減少噪音和污染，交通和建筑管理部門要求施工用得混凝土集中生產(chǎn)和管理，這樣，不僅要求混凝土得配料精度高，而且要求生產(chǎn)速度快，因此，混凝土生產(chǎn)過程中攪拌設(shè)備自動(dòng)控制系統(tǒng)日益受到人們的重視。可編程控制器（PLC）具有可靠性高、功能完善、編程簡(jiǎn)單且直觀，能夠有效地彌補(bǔ)繼電器控制系統(tǒng)得缺陷。
本文介紹的混凝土攪拌站自動(dòng)化控制系統(tǒng)，此系統(tǒng)以工控機(jī)為上位機(jī)，PLC為下位機(jī)，根據(jù)混凝土攪拌站的工藝流程，進(jìn)行PLC系統(tǒng)的設(shè)計(jì)，并采用力控5.0組態(tài)軟件，設(shè)計(jì)一組系統(tǒng)畫面、報(bào)表、重量曲線和其它功能窗口等動(dòng)靜態(tài)界面。

Abstract
With today's world of science and technology advancing by leaps and bounds, electrical automation technology have become increasingly improved and optimized, including programmable controllers more widely used in production, greatly enhanced the production of human life and the degree of automation in the development of society and The progress of mankind has played a positive role. Since reform and opening up, China's economic construction rapid development, overall national strength constantly enhance the state's infrastructure construction investment increased, pulling the city ready-mixed concrete products to the rapid development, so that the concrete mixing stations have larger space for development .
As the basis for many large projects and construction works have started building high-quality projects need high-quality concrete, but as people in enhancing awareness of environmental protection, in order to reduce noise and pollution, transport and construction management department for the construction of concrete used on the production And management, so that not only requires a concrete batching high precision, but also for the production speed, therefore, concrete mixing equipment in the production process control systems have become an increasing people's attention. Programmable Logic Controller (PLC) with high reliability, with perfect functions, programming is simple and intuitive, can effectively make up for deficiencies in the relay control system.
 This paper describes the concrete mixing plant automation control systems, this system to IPC for the PC, PLC for the next crew, in accordance with the process of concrete mixing stations, the PLC system design and use of controlled 5.0 configuration software, design a Group screen system, statements, the weight of windows and other features, such as static and dynamic interface.
