Electrical signal transmission method, electrical signal transmission control chip, and electrical signal transmission system

An electrical signal transmission control chip applied to an electrical signal transmission system, wherein the electrical signal transmission system includes at least two first transmission interfaces and at least one second transmission interface;

• electrical signal transmission modes of the electrical signal transmission system include a first transmission mode and a second transmission mode;
• the first transmission mode is used for controlling a total transmission power of the at least two first transmission interfaces and the at least one second transmission interface to be less than or equal to a first preset power;
• and the second transmission mode is used for controlling a maximum transmission power of a second transmission interface in the at least one second transmission interface to be the first preset power;
• the electrical signal transmission control chip comprises a control circuit and a determination circuit, wherein
• the determination circuit is configured to determine whether the second transmission mode is turned on, and transmit a determination result to the control circuit;
• the control circuit is configured to:
• if the determination result is that the second transmission mode is turned on, disable a function of the first transmission mode and make the maximum transmission power of the second transmission interface be the first preset power in response to an instruction of turning on the second transmission mode;
• if the determination result is that the second transmission mode is not turned on, feed back the determination result to the determination circuit;
• the determination circuit is further configured to:
• if the second transmission mode is not turned on, determine whether the first transmission mode is turned on, and transmit another determination result to the control circuit;
• the control circuit is further configured to:
• if the determination result is that the first transmission mode is turned on, make the total transmission power of the at least two first transmission interfaces and the at least one second transmission interface less than or equal to the first preset power in response to an instruction of turning on the first transmission mode;
• if the determination result is that the first transmission mode is not turned on, make the maximum transmission power of the second transmission interface be a second preset power;
• the second preset power is less than the first preset power.
