Abstract

The invention discloses a VHF transceiver switcher. The VHF transceiver switcher comprises an interface module, a switching module, a control module and a display module. The interface module is provided with eight groups of site access interfaces, and each group of site access interfaces comprises six groups of transceiver audio control lines and at least one group of standby transceiver audio control lines. When the first transceiver needs to be switched to the standby transceiver, the control module determines a first transceiver audio control circuit corresponding to the first transceiveraccording to user operation, and then controls the switching module to disconnect the input end of the first transceiver audio control circuit. The output end of the first transceiver audio control circuit is connected with the input end of the standby transceiver audio control circuit; and the display module is used for displaying the transceiver operation condition of each group of stations. According to the technical scheme, when the transceiver breaks down, the standby transceiver can be switched in real time, and normal communication is not affected.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a VHF transceiver switcher. Background technique [0002] Ultrashort wave transceiver (VHF transceiver) refers to the equipment used to receive and transmit ultrashort wave radio frequency signals, and is an important part of the ultrashort wave communication system working in the very high frequency band (30 ~ 300MHz). The ultra-short wave transmitter is a device used to modulate the carrier signal generated by the information signal to form a modulated carrier, and then feed it to the antenna through frequency conversion and amplification, and transmit it into space in the form of electromagnetic waves. An ultrashort wave receiver is a device that receives modulated radio waves and converts them into raw information. [0003] In the existing communication system, each site will be equipped with multiple transceivers (up to 6). When a transceiver fails at a site, mainten...
