AI Technical Summary
Existing circuit fault detection systems are difficult to detect other types of faults except for circuit breakers, and the fault detection accuracy is insufficient.
Using a combination of voltage division module and measurement module, the voltage division structure formed between the power supply voltage end and the ground terminal of the first voltage division module and the second voltage division module are mapped to a measurable range. The first measurement module is responsible for collecting the voltage values of these voltage division points and comparing them with the preset voltage range to determine the fault type.
It realizes accurate detection and determination of the fault type of the circuit under test, improves the sensitivity and reliability of fault detection, simplifies circuit design, reduces costs, and is suitable for fault diagnosis scenarios of various sensors and other circuits.
