文章探索的是有关发动机性能测试数据方面的技术。对发动机需要测量的数据有转速、扭矩、功率、耗油率、耗油量、机油压力、机油温度、冷却水温等参数。发动机测试数据采集与处理系统由上位机和下位机组成。下位机主要采用AT89C52单片机,用汇编语言编写相应的程序,用模-数转换器ADC0809把模拟量转换为数字量;而上位机采用PC机,程序语言用VB,存储数据采用Access数据库,最终实现试验数据的显示、存贮与打印等功能。
The article explores technologies related to engine performance test data. The need to measure the engine speed, torque, power, fuel consumption, fuel consumption, oil pressure, oil temperature, cooling water temperature and other parameters. Engine test data acquisition and processing system consists of upper computer and lower computer. The lower computer mainly adopts AT89C52 one-chip computer, write the corresponding program with the assembly language, convert the analog quantity into the figure quantity with ADC-808 converter ADC0809; The upper computer uses PC, programming language uses VB, stores the data to use Access database, final realization Test data display, storage and printing functions.
