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.
