Abstract
The invention provides a method for predicting a domestic power supply circuit fault. An alternating current (AC)-direct current (DC) power source can supply direct current power for a voltage signal adjusting unit, a modulus converting unit, a singlechip controlling unit and a display unit. Voltage of the power supply circuit is weakened by the voltage signal adjusting unit. Analog signals adjusted by the voltage signal adjusting unit are converted into digital signals by the modulus converting unit. Converted data of the modulus converting unit are read by the singlechip controlling unit. A long-term heavy loading load of the power supply circuit can lead to rapid aging of the circuit, a certain point can be carbonized and impedance of the power supply circuit becomes large due to the rapid aging of the circuit. The voltage of the power supply circuit is changed obviously when current of the power supply circuit is changed. The singlechip controlling unit judges whether the voltage of the power supply circuit is in a normal range or not according to the data. The domestic power supply circuit fault is predicted according to the situation of voltage pulsation, and fault information is displayed on the display unit.
