Low-power-consumption control method and system of embedded system and storage medium

The invention relates to the technical field of embedded systems, and discloses a low-power-consumption control method and system of an embedded system and a storage medium. The low-power-consumptioncontrol method comprises the steps: in the system operation process, if the current driving state or the system operation state is busy, monitoring the current system scheduling interval duration; ifthe duration is greater than the duration threshold, controlling the system to be switched to a light sleep mode, and controlling the main frequency to be reduced to a first clock frequency; if the duration is not greater than the duration threshold, controlling the system to be switched to a moderate sleep mode, controlling the main frequency to be reduced to a second clock frequency, and switching the current first clock source to the second clock source; wherein the second clock frequency is not higher than the first clock frequency, and the second clock source is lower than the working frequency of the first clock
