介紹了電控發(fā)動機微機控制故障模擬系統(tǒng)的組成和工作原理,闡述了微機控制故障模擬系統(tǒng)的微機控制單元、故障模擬電路和電路顯示板的結(jié)構(gòu)特征和設(shè)計。該系統(tǒng)是在原車基
礎(chǔ)上對發(fā)動機的微機系統(tǒng)進行線路改造,并另設(shè)一套微機控制故障模擬系統(tǒng),微機控制故障模擬系統(tǒng)可不斷重復(fù)產(chǎn)生發(fā)動機不同工況下傳感器、執(zhí)行器、控制單元、控制電路的各種模擬故障,為使用者提供豐富的檢測內(nèi)容和便利的檢測端口。
關(guān)鍵詞:電控發(fā)動機;故障模擬;設(shè)計方法
Abstract :The work on principle and constitution of t rouble simulate system in computer cont rolled for elec2 t ronic cont rolled engine is int roduced in this paper. It expounds the main st ructure character and design meth2 ods of computer cont rol unit ,circuit s of t rouble simulate and showing board about the t rouble simulate system in computer cont rolled. Trouble simulate system of computer cont rolled for elect ronic cont rolled engine is a de2 vice on circuit s of automobile engine computer system that is changed. It can continuously produce various kinds of simulate t rouble of the sensor ,actuator ,elect ronic cont rol unit and cont rol circuit . It supply abundant inspect content and convenient inspect port for user.
