Abstract

An electrical signal transmission method applied to an electrical signal transmission system includes first transmission interfaces and second transmission interface(s). Electrical signal transmission modes of the electrical signal transmission system include: a first transmission mode used for controlling a total transmission power of the first transmission interfaces and the second transmission interface(s) to be less than or equal to a first preset power, and a second transmission mode used for controlling a maximum transmission power of a second transmission interface to be the first preset power. The electrical signal transmission method includes: determining whether the first transmission mode is turned on; if yes, making the total transmission power of the first transmission interfaces and the second transmission interface(s) less than or equal to the first preset power; and if no, making the maximum transmission power of the second transmission interface be a second preset power.
