Abstract

See full text

A method is disclosed for detecting power interruption duration of an electronic device. The method can include establishing a curve model of linearly synthesized values of temperature sensor readings versus time; after power-on, acquiring each of the initial temperature values by respective temperature sensors mounted on the electronic device, and transmitting the temperature initial values to a microprocessor; calculating a linearly synthesized value of the temperature sensor readings of the electronic device according to a power-on duration for this time and a stored curve model, and storing the linearly synthesized value of the temperature sensor readings as a basis for calculating the power interruption duration thereafter. When the electronic device is powered on again after power interruption, a linearly synthesized value of the temperature sensor readings according to the power-on time for this time can be calculated, and used for calculating the power interruption duration thereafter.
