Wireless communication system and radio frequency transmission control method

Abstract

The invention discloses a wireless communication system and a radio-frequency transmission control method. The wireless communication system comprises a plurality of transmitters and a multi-path receiver, wherein the multi-path receiver comprises a plurality of channels, and each channel is corresponding to one transmitter for communication. Each transmitter is connected with a transmission end power supply by a transmission end control module, and the multi-path receiver is connected with a receiving end power supply by a receiving end control module; the receiving end control module is used for monitoring and controlling the power supply state of each channel of the multi-path receiver, generating a control command and sending the control command to the transmission end control module of each transmitter; the control command comprises at least one channel logo and power on / off control characters; the transmission end control module of each transmitter is used for receiving the control command, and only the transmission end control module containing a matched channel logo can be used for controling the power on or the power off of the transmitters according to the power on / off control characters.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a high-power wireless communication system and a radio frequency emission control method. Background technique [0002] With the continuous development of the communication industry, people place higher expectations on communication technology and put forward higher requirements. COFDM (Coded Orthogonal Frequency Division Multiplexing, Coded Orthogonal Frequency Division Multiplexing) and other wireless digital audio and video communication technologies emerged with the urgent needs of social development, and are widely used in fire protection, water conservancy, transportation, security and national defense. [0003] At present, as a wireless audio and video communication device for transmitting multimedia information such as wireless audio and video, due to its high power and wireless transmission characteristics, the distance between the transmitter and receiver...

AI Technical Summary

Problems solved by technology

[0005] (1) The constant transmission state of the transmitter is actually a source of interference for other wireless devices, which is likely to cause blocking interference to other devices' communications;

[0006] (2) The human body is exposed to high-power transmitters for a long time, which may easily cause radio frequency radiation damage;

[0007] (3) The high-power transmitter is always in the state of constant transmission, and the equipment is prone to fatigue, resulting in a reduction in service life; and the state of constant transmission will waste power resources
