一种电力中断检测方法，其应用于一供电系统以及一设备，检测方法包括：藉由电力中断检测模组的电压侦测单元侦测电力中断检测模组的限压元件的限压电压是否等于0。当电压侦测单元于第一时间所侦测到的限压电压等于0时，电压侦测单元提供第一电压讯号至限压元件，第一电压讯号带有第一电压。藉由电压侦测单元于第二时间侦测限压元件的限压电压是否小于第一电压，第二时间晚于第一时间。当电压侦测单元在第二时间所侦测到的限压电压小于第一电压时，电压侦测单元输出供电讯号至备用电源，使备用电源供电至设备。; A method for status detection of power supply, which applied to a power supply system and an equipment. The power supply system comprises a power, a switch, an emergency power and a power supply status detection module. The power supply status detection module comprises a voltage limitation unit and a voltage detection unit. The voltage limitation unit comprises a voltage limitation element. The method comprises detecting, by the voltage detection unit, whether a voltage of the voltage limitation element is zero; providing, by the voltage detection unit, a first voltage signal having a first voltage to the voltage limitation element if the voltage of the voltage limitation element, detected by the voltage detection unit at a first time, is zero; detecting, by the voltage detection unit at a second time, whether the voltage of the voltage limitation element is smaller than the first voltage, wherein the second time is later than the first time, and providing, by the voltage detection unit, a power supply signal to the emergency power supplying power to the equipment if the voltage of the voltage limitation element, detected by the voltage detection unit at the second time, is smaller than the first voltage. |
