摘　　要：介绍一种用于大型油库放油控制与管理的微机系统。该系统采用主从式上下两级微机网络结构,上位机完成系统的管理,控制下位机执行具体的操作。发油过程中,在实时测量油温的基础上对油量进行有效体积折算,并精确调整提前关阀的时间,从而提高了发油量的准确度。This paper introduces a microcomputer-based system of controlling sale-oil and managing in big oil banker. Two levels master-slave microcomputer network is applied to this system. The master computer manages the system and controls the slave microcomputer to excuse the operations in details. When selling oil, the system changes the weight of sale-oil into an effective volume on the base of the oil-temperature measurement on the spot, and adjusts the time to turn off the valve in advance, so it can improves the accuracy of sale-oil. At last the paper gives two measures to control the accuracy of sale-oil measurement from being affected by some man-made factors.
