摘要
为缩小实际故障数据样本与原猜想数据样本之间的误差值水平,实现对电路故障行为的准确诊断,设计汽车燃油泵控制电路故障自动化诊断系统.以集成控制电路为核心,分别连接微处理器结构与A/D转换模块,完成自动化诊断系统的硬件执行环境搭建.根据故障指标取值结果,实施数值量的警限区域划分,再以此为基础,完成实际诊断模式判定,结合相关应用模块,实现汽车燃油泵控制电路故障自动化诊断系统的设计.实验结果表明,自动化诊断系统作用下,实际故障数据样本与原猜想数据样本之间的误差值水平可被控制在10%之内,对于已发生的汽车燃油泵控制电路故障行为能够做出准确诊断.
Abstract
In order to reduce the error value level between the actual fault data sample and the original conjecture data sample and realize the accurate diagnosis of circuit fault behavior,the automatic fault diagnosis system of automobile fuel pump control circuit is designed.With the integrated control circuit as the core,the microprocessor structure and A/D conversion module are connected respectively to complete the hardware execution environment construction of the automatic diagnosis system.According to the value result of the fault index,the alarm limit area of the value is divided,and then on this basis,the actual diagnosis mode judgment is completed,and the design of the automatic fault diagnosis system of the automobile fuel pump control circuit is realized.The experimental results show that under the action of the automatic diagnosis system,the error value level between the actual fault data sample and the original conjecture data sample can be controlled within 10%,and the fault behavior of the automobile fuel pump control circuit can be accurately diagnosed.
