Design of Automatic Fault Diagnosis System for Automobile Fuel Pump Control Circuit
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.
