Control method and system for power source, and device and medium

A computer device, comprising:

• at least one processor;
• and
• a memory, storing a computer program that is configured to run in the at least one processor, wherein the computer program, upon execution by the at least one processor, is configured to cause the at least one processor to:
• detect electric power quality of multiple channels of inputs of a power source;
• in response to the electric power quality of the multiple channels of inputs being normal, acquire and compare a resistance of a relay under a circumstance that the power source is respectively working at each channel of input;
• in response to the resistance of the relay at several channels of inputs failing to meet a preset condition, take other channel of input meeting the preset condition as an input of the power source;
• in response to the resistance of the relay at each channel of input meeting the preset condition, acquire a duration how long each power source is working at one channel of input among the multiple channels of inputs;
• and
• in response to the duration how long the power source is working at the channel of input among the multiple channels of inputs being greater than a threshold value, adjust the power source to work at other channel of input.

A non-transitorycomputer readable storage medium, storing a computer program and the computer program, upon execution by a processor, is configured to cause the processor to:

• detect electric power quality of multiple channels of inputs of a power source;
• in response to the electric power quality of the multiple channels of inputs being normal, acquire and compare a resistance of a relay under a circumstance that the power source is respectively working at each channel of input;
• in response to the resistance of the relay at several channels of inputs failing to meet a preset condition, take other channel of input meeting the preset condition as an input of the power source;
• in response to the resistance of the relay at each channel of input meeting the preset condition, acquire a duration how long each power source is working at one channel of input among the multiple channels of inputs;
• and
• in response to the duration how long the power source is working at the channel of input among the multiple channels of inputs being greater than a threshold value, adjust the power source to work at other channel of input.
