Method for controlling transmission power of digital infrared conference unit, communication apparatus, and medium

A method for controlling transmission power of a digital infrared conference unit, wherein the method is applied to a first infrared conference unit, the first infrared conference unit is located in an infrared conference system, the infrared conference system comprises an infrared conference host and a plurality of infrared conference units, and the method comprises:

• sending a first uplink signal to the infrared conference host at first transmission power, wherein the first infrared conference unit is any one of at least one infrared conference unit among the plurality of conference units, and the at least one infrared conference unit simultaneously sends the first uplink signal to the infrared conference host;
• receiving a first downlink signal for the first uplink signal from the infrared conference host, wherein the first downlink signal contains first control data for each of the at least one infrared conference unit, the first control data for each infrared conference unit is determined by the infrared conference host according to a first signal strength of the first uplink signal of each infrared conference unit and a preset signal strength, and the first control data for each infrared conference unit is used to determine a next transmission power of each infrared conference unit;
• obtaining first control data for the first infrared conference unit from the first downlink signal;
• determining second transmission power of the first infrared conference unit according to the first control data for the first infrared conference unit;
• and
• sending a second uplink signal to the infrared conference host at the second transmission power, wherein a second signal strength of the second uplink signal of the first infrared conference unit received by the infrared conference host is the preset signal strength.

A communication apparatus comprising a processor and a memory, wherein the processor is connected to the memory, the memory is configured to store a computer program, and the processor is configured to execute the computer program stored in the memory to make the communication apparatus perform:

• receiving a first uplink signal of each of at least one infrared conference unit from the at least one infrared conference unit among a plurality of conference units, wherein the first uplink signal of each infrared conference unit is sent by each infrared conference unit at first transmission power of each infrared conference unit, wherein the communication apparatus and the plurality of conference units are located in a same infrared conference system;
• obtaining a first signal strength of the first uplink signal of each infrared conference unit;
• determining first control data for each infrared conference unit according to the first signal strength corresponding to each infrared conference unit and a preset signal strength, wherein the first control data for each infrared conference unit is used to determine a next transmission power of each infrared conference unit;
• sending a first downlink signal to the at least one infrared conference unit, wherein the first downlink signal contains the first control data for each infrared conference unit;
• and
• receiving a second uplink signal of each infrared conference unit from each infrared conference unit, wherein a second signal strength of the second uplink signal of each infrared conference unit is the preset signal strength, the second uplink signal is sent by each infrared conference unit at second transmission power, and the second transmission power is determined by each infrared conference unit according to the first control data for each infrared conference unit.
