A power consumption management method for electric devices, comprising: acquiring identification information of an electric device in a power-on state in a monitoring area; and acquiring monitoring data of the monitoring area, determine whether a user exists in the monitoring area or not according to the monitoring data; when the user does not exist in the monitoring area, determining a type set to which the identification information belongs; when determining that the identification information is identification information of a first type set, powering off the electric device; and when determining that the identification information is identification information of a second type set, beginning timekeeping, and when a timekeeping duration reaches to a preset duration matched with the identification information, powering off the electric device; the identification information is the identification information of the first type set, or the identification information of the second type set, the identification information of the first type set is information that characterizes the electric device as an instantaneous electric device, the instantaneous electric device refers to the electric device that is to be powered off when the user leaves away from the monitoring area for a first period of time, the identification information of the second type set is information that characterizes the electric device as a short-time electric device, the short-time electric device refers to the electric device that is to be powered off when the user leaves away from the monitoring area for a second period of time; the first period of time is less than the second period of time. acquiring identification information of an electric device in a power-on state in a monitoring area; and acquiring monitoring data of the monitoring area, determine whether a user exists in the monitoring area or not according to the monitoring data; when the user does not exist in the monitoring area, determining a type set to which the identification information belongs; when determining that the identification information is identification information of a first type set, powering off the electric device; and when determining that the identification information is identification information of a second type set, beginning timekeeping, and when a timekeeping duration reaches to a preset duration matched with the identification information, powering off the electric device; the identification information is the identification information of the first type set, or the identification information of the second type set, the identification information of the first type set is information that characterizes the electric device as an instantaneous electric device, the instantaneous electric device refers to the electric device that is to be powered off when the user leaves away from the monitoring area for a first period of time, the identification information of the second type set is information that characterizes the electric device as a short-time electric device, the short-time electric device refers to the electric device that is to be powered off when the user leaves away from the monitoring area for a second period of time; the first period of time is less than the second period of time.
