The embodiment of the invention discloses low-power consumption power supply management equipment for embedded Linux equipment. The low-power consumption power supply management equipment comprises a Linux kernel power supply management interface unit, an idle mode processing unit, an event reduction processing unit and a central processing unit (CPU) performance control unit, wherein the Linux kernel power supply management interface unit is used for providing a quick adjustment interface for the voltage and the frequency of embedded high-energy-consumption peripheral equipment; the idle mode management unit is used for providing an entering and existing processing method for an idle mode of the embedded Linux system; the event reduction processing unit is used for providing a processing method for making the embedded equipment work in the idle mode for a longest time; and the CPU performance control unit is used for providing a processing method for reducing the working frequency of a CPU for the embedded Linux system. By implementing the low-power consumption power supply management equipment, the electric power consumption of the embedded Linux equipment can be reduced, and the service life of a processor of the embedded Linux equipment can be prolonged.
