Otherwise Cutoff current sensor exists abnormal.
Especially, the current excitation circuit specifically for：Before the system operation of the application current sensor to be measured
After operation, respectively increase a definite value current excitation to current sensor to be measured.
Especially, the main control circuit specifically for：Normally run in the system of the application current sensor to be measured
Before, judge whether the current value that current sensor to be measured is detected is identical with definite value electric current, if identical, judge that electric current to be measured is passed
Sensor otherwise judges that current sensor to be measured is present abnormal in the absence of abnormal；In the system of the application current sensor to be measured
After operation, a definite value current excitation is increased to current sensor to be measured, judge the current value that current sensor to be measured is detected
It is whether identical with definite value electric current, judge that current sensor to be measured, in the absence of abnormal, otherwise judges current sense to be measured if identical
Device occurs in that exception in system operation.
Abnormality of current sensor detection method proposed by the present invention and device are before the system operation of applied current sensor
And after operation, by current excitation circuit one definite value current excitation of each extra increase, judge that electric current is passed by main control circuit
Whether the current value that sensor is detected is identical with extra increased definite value electric current, and Cutoff current sensor is without exception if identical,
Otherwise there is exception in Cutoff current sensor, simply can rapidly judge that current sensor, with the presence or absence of abnormal, improves system
Security reliability, it is to avoid cause unnecessary loss.
