椭圆齿轮计量系统的改进

Improvement of Measurement System of Elliptic Gear

以加油站椭圆齿轮流量计计量系统为改造对象,针对原有系统功能单一、只能记录流量值、无法满足现代化要求等缺点,对系统进行了改造,使新增单片机控制系统和上位机系统实现如下功能:实时显示计量值;实时换算,显示每次加油费用;设置需加油最大值;通过总线技术与上位机通信,实时设置汽油单价;通过上位机实时记录每次加油产生的费用和油量值,同时把数据传至开票处开票。

Took the elliptic gear flow meter of gas station as transformation object, according to the problems such as single function of primal system, only record the flow value, without any special characteristic to satisfy the modern require- ments, the flow meter system transformation was did. adding new single-chip microcomputer control system and host com- puter system, which achieved the function as follows.. 1） real-time display flow meter value; 2） real-time conversion show- ing the each oil costs; 3） setting the max of fuel charge; 4） through the communication between bus technology and host computer, real-time setting the gasoline price; 5） through host computer recording each oil cost and oil mass during the re- fueling, the record data will be transferred to check desk for convenient billing.
