摘要

平朔安太堡露天煤礦位于朔州市區(qū)與平魯區(qū)交界處，現(xiàn)為大型露天開采的煤礦。油庫是其最重要的部門之一，因此油庫收、發(fā)油計量系統(tǒng)的設(shè)計是一項十分重要的工程。
隨著計算機(jī)技術(shù)、工業(yè)控制技術(shù)的迅猛發(fā)展，計量方式向自動化、智能化、遠(yuǎn)程化方向發(fā)展。本文通過對安太堡礦的實際情況和油庫計量系統(tǒng)的實際要求的分析，構(gòu)建了一個上位機(jī)計量系統(tǒng)。該系統(tǒng)上位機(jī)采用工控計算機(jī)與北京亞控的工控組態(tài)軟件的組合，下位機(jī)分散控制的構(gòu)成方式采用了三菱Q系列PLC，構(gòu)成了一個集散控制系統(tǒng)。組態(tài)軟件與PLC之間的通信采用了Q系列高性能型PLC專用的MELSEC通信協(xié)議。通過對工控組態(tài)軟件進(jìn)行組態(tài)，讓其具備了趨勢顯示、報警判斷、歷史數(shù)據(jù)記錄以及報表打印等監(jiān)控功能，將自動化技術(shù)、計算機(jī)技術(shù)、通信技術(shù)融為一體，計算精度高，性能穩(wěn)定、實用性強(qiáng)，提高了工作效率。
    本系統(tǒng)為油庫計量系統(tǒng)提供了一個切實可行的方案，對大規(guī)模的收、發(fā)油控制系統(tǒng)具有一定的參考價值。系統(tǒng)的構(gòu)建思想和方法對于其它自動化系統(tǒng)也有一定的借鑒意義。

Abstract

The Antaibao Open-air coal mine is located in the jiont point of Shuozhou and Pinglu area , it is the large-scale open-air mining coal mine.The fuel depot is one of its most important departments, therefore the fuel depot measurement system’s design is an extremely important project.
Along with the computer technology, the industrial control technology swift and violent development, the measurement style develops towards the automation, the intellectualization, the long-distance direction. This article analyze according to the Antaibao’s actual situation and the fuel depot measurement system’s particular demand，and construct a calculation system on up-location computer.On this system the up-location computer is composed of industrial computer and the Beijing configuration software, the disperser control of lower position computer use sanling PLC of Q series, which constitute a collection and distribution control system. The correspondence between the configuration software and the PLC uses the special-purpose MELSEC communication protocol of Q series high performance PLC. By using the configuration software , it has several kinds of monitoring functions , for example, the tendency judgment, history data record and report form printing and so on. The automation technology, the computer technology and the communication has been merged into one, it has high calculation precision,stable performance,particular use, which enhanced the working efficiency.
This system has provided a practical and feasible plan for the fuel depot measurement system, it has certain reference value for the fuel depot system when receives and distribute oil.The thought and method of system construction also have certain model significance for other automation system.
Key words: Measurement by up-location computer; Automation; Configuration software; Monitoring
