PAGE  PAGE 16 摘 要：本文介绍了一种新型的电子式汽车电子式油耗和里程计算器。本文介绍了由MCS一51系列单片微型计算机构成的智能油耗和里程计算器。该仪表以8051单片机为核心，用CD4511设计接口和LED数码管显示汽车总行驶里程和本次行驶里程由于8051内部设有程序存贮器，以及能计量汽车发动机的燃油消耗总量和即时消耗量 。给出了该仪表的硬件框图和部分软件框图。这种新型的电子式油耗和里程计算器适用于交通运输、电站以及厂矿油田，建筑工地等分散作业的船舶和车辆管理工作的需要。该汽车电子表较机械式汽车里程表具有精度高，误差小，显示清楚醒目，工艺简单等优点。 智能化创造了条件。本设计采用MCS一51系列单片微型计算机研制成智能电子式油耗和里程计算器，为汽车企业部门提高管理水平提供了技术手段，对企业节制能源流失、进行成本核算等具有积极的作用。 关键词：单片机 里程表 油耗表 数字方式 传感器  Abstract This paper introduces a new type of electronic automotive electronic fuel consumption and mileage calculator. This paper introduces the MCS-51 series single-chip micro-computer form of intelligent fuel consumption and mileage calculator. The instrument to 8051 as the core, using CD4511 design LED digital display interface and total vehicle mileage and mileage of this process because the 8051 has an internal memory, and can measure the total vehicle engine fuel consumption and real consumption . Shows the hardware block diagram of the instrument and some software structure. This new type of electronic fuel consumption and mileage calculator applies to transportation, power plants and oil plants, mines, construction sites and operation of ships and vehicles scattered management needs. The automotive electronics than mechanical car odometer table with high precision, small error, show a clear eye-catching, processing and simple. Create the conditions for intelligent. This design uses MCS-51 series single-chip micro-computer research into intelligent electronic fuel consumption and mileage calculator for the automotive business sector to improve management level to provide technical means, the energy loss of corporate control, costing and other positive role.
