The characteristic parameters include waveform frequency, amplitude, phase and high harmonic component, and the high harmonic component refers to a signal with a frequency higher than the fundamental frequency, namely a signal higher than 50Hz, and the signal with the frequency higher than the fundamental frequency becomes high harmonic, so that certain devices may generate specific high harmonic components during operation, which may be used as an index for identifying the devices.
Specifically, by analyzing the voltage waveform and the current waveform, the characteristic parameters of the current electric equipment can be extracted.
S330, matching the characteristic parameters of each current electric equipment with a preset equipment characteristic parameter sample library.
The device characteristic sample library stores characteristic parameters corresponding to different electric equipment types.
Specifically, the method and the device collect characteristic parameters of different electric equipment types in various working states in advance, and establish an equipment characteristic sample library based on statistical analysis, wherein each sample comprises equipment types, equipment states and corresponding characteristic parameters.

s141, determining the basic priority of each electric equipment based on the equipment priority setting and the equipment type of each electric equipment.
Wherein the base priority includes a highest priority, an intermediate priority, and a lowest priority.
It is noted that before the power supply and the output power adjustment or the disconnection of the target electric equipment are determined according to the priority, the magnitude relation between the current capacity of the power supply and the first preset capacity threshold is judged, and when the current capacity of the power supply is greater than or equal to the first preset capacity threshold, the normal power supply of the target electric equipment is maintained, so that the energy of the power supply is sufficient, the normal power supply of the target electric equipment is maintained, and the requirement of normal use of the electric equipment by a user is met; when the current capacity of the power supply is smaller than a first preset capacity threshold, power supply, output power adjustment or cutting-off of the target electric equipment are determined based on the priority, so that the service time of the power supply is prolonged.

And S146, when the current capacity of the power supply is smaller than a third preset capacity threshold, reducing the basic priority of all priority electric equipment.
The third preset capacity threshold value indicates that the current capacity of the power supply is low, and the power supply can maintain the power supply for a short time, so that the priority of all priority electric equipment needs to be reduced. Meanwhile, an alarm signal with low electric quantity can be sent.
And S147, recovering the basic priority of all priority electric equipment when the current capacity of the power supply is larger than a second preset capacity threshold.
S148, determining the final priority of the target electric equipment based on the adjusted basic priority.
