PLC在電子秤自動配料系統(tǒng)中的應(yīng)用

摘  要                   
電子皮帶秤配料系統(tǒng)是一種集輸送、計量、配料于一體的在線測量動態(tài)自動衡器。該系統(tǒng)由一臺或多臺配料電子皮帶秤組成，不僅能夠顯示瞬時流量和累計量，還可以根據(jù)輸送帶的瞬時流量與設(shè)定值的偏差去調(diào)整給料量的大小使瞬時流量更加接近設(shè)定值，構(gòu)成一個環(huán)控制系統(tǒng)，達到恒定瞬時流量的目的。隨著工業(yè)生產(chǎn)的迅速發(fā)展，電子皮帶秤配料系統(tǒng)的需求量日益增大，已被廣泛應(yīng)用于冶金、建材、電力、化工、食品等行業(yè)的工藝控制。同時，隨著電子計算機技術(shù)和自動控制技術(shù)的飛速發(fā)展，該系統(tǒng)所應(yīng)用的技術(shù)更加先進，領(lǐng)域更加廣泛，可以采取的方案更加靈活多樣，而且，由于系統(tǒng)往往耗資巨大，用戶的實際條件也各不相同。因此，慎重，全面地選擇一套合理、完善、經(jīng)濟的方案就顯得尤其重要。本論文研究的電子秤自動配料系統(tǒng)是基于國內(nèi)某研磨材料有限責任公司電子秤自動配料系統(tǒng)的要求而設(shè)計的。本配料系統(tǒng)已在該公司內(nèi)投入實際運行，控制效果良好，使企業(yè)取得了良好的經(jīng)濟效益。

PLC Application on Automatic Weightometer Burden System
Abstract 
Belt scales batching system is a kind of integrating transportation, measuring, mixing in an online automatic weighing apparatus measured dynamic. This system consists of one or more ingredients belt scales, can show not only transient flow and total amount of conveyor belt, can also according to the value of the instantaneous flow deviation to adjust to the size of the feed to flow, constitute a closer setting control system, and achieve constant flow of purpose. Along with the rapid development of industrial production, electronic belt scale increasing demand of burdening system, was widely applied in a pan of metallurgy, power, chemical industry, food industry etc of process control. At the same time, along with the computer technology and the rapid development of the automatic control technology, the system application technology more advanced, more extensive, field can take the scheme is more agile diversity, and, due to the system often costly, users of the actual conditions are also different. Therefore, careful, choose a reasonable, perfect, economic solution appears especially important. This paper studies the automatic weightometer burden system which is based on a domestic grinding materials limited liability company automatic weightometer burden system requirements and design. The ingredients in this company has system into practice and control effect is good, causes the enterprise to have achieved good economic benefit.
