Talkback relay system and radio frequency transceiving control method and device thereof

Abstract

The invention relates to a talkback relay system and a radio frequency transceiving control method and device thereof, computer equipment and a storage medium. The talkback relay system comprises a master control relay station and a slave control relay station; wherein the master control relay station is used for sending a time slot control signal to the slave control relay station; the slave control relay station is used for adjusting the radio frequency signal transmitting time and / or the radio frequency signal receiving time of the slave control relay station according to the time slot control signal; the main control relay station is also used for adjusting the radio frequency signal transmitting time and / or the radio frequency signal receiving time of the main control relay station according to the time slot control signal; therefore, when any one of the master control relay station and the slave control relay station receives the radio frequency signal, other relay stations except any one relay station can be prevented from transmitting the radio frequency signal in the period when any one of the master control relay station and the slave control relay station receives the radio frequency signal. According to the talkback relay system, the blocking effect of transmitting of the downlink frequency on receiving of the uplink frequency in the talkback relay system can be avoided without using a duplexer, so that the cost of the talkback relay system is reduced, and the deployment flexibility of the talkback relay system is improved.

Description

technical field [0001] The present application relates to the field of intercom technology, in particular to an intercom relay system and its radio frequency transceiver control method, device, computer equipment and storage medium. Background technique [0002] The existing intercom repeater system includes multiple repeater stations. The repeater in the intercom repeater system, whether it is an analog system or a digital system, generally adopts the method of sending and receiving different frequencies, that is, the uplink frequency is used for reception, and the downlink frequency is used for transmission. The distance between the uplink frequency and the downlink frequency is sufficient. interval. In order to prevent the blocking effect of the transmission of the downlink frequency on the reception of the uplink frequency, such as figure 1 As shown, a duplexer is usually added to the intercom repeater system. The essence of the duplexer is two band-pass filters, the ...

AI Technical Summary

Problems solved by technology

If no duplexer is added, the downlink transmission signal of the intercom relay system will cause great blocking and interference to the uplink reception signal of the intercom relay system

[0003]However, when deploying the intercom relay system, since different intercom relay systems have different uplink and downlink frequencies of the repeater, it is necessary to The corresponding duplexers are customized for different frequencies of the relay system, which leads to high cost of the intercom relay system on the one hand, and inconvenient deployment of the intercom relay system. Once the uplink and downlink of the intercom relay system Frequency changes, duplexer may need to be re-customized
