A relay communication device for an ultrashort wave vehicle-mounted station

Abstract

The invention discloses a relay communication device for an ultrashort-wave vehicle-mounted platform, and the device comprises an ultrashort-wave antenna, a duplexer, a first digital ultrashort-wave radio station, a second analog ultrashort-wave radio station, a third digital ultrashort-wave radio station, a fourth analog ultrashort-wave radio station, and an access selection unit. The ultrashort-wave antenna receives a radio frequency signal, and transmits the radio frequency signal to the duplexer. The radio frequency signal enters into the first digital ultrashort-wave radio station or the second analog ultrashort-wave radio station through the duplexer. The first digital ultrashort-wave radio station and the second analog ultrashort-wave radio station can respectively convert the radio frequency signal into a voice signal, and the voice signals are selected through the access selection unit to enter into the third digital ultrashort-wave radio station or the fourth analog ultrashort-wave radio station. The third digital ultrashort-wave radio station and the fourth analog ultrashort-wave radio station can convert the voice signals into radio frequency signals which are transmitted to the ultrashort-wave antenna through the duplexer.

Description

technical field [0001] The invention belongs to the technical field of ultrashort wave relay communication, in particular to a relay communication device of an ultrashort wave vehicle-mounted station, which is suitable for ultrashort wave relay communication of relay or analog-to-digital conversion. Background technique [0002] The radio station has a digital ultrashort wave radio station and an analog ultrashort wave radio station. According to the conditions of the communication equipment application site and the requirements of users, there are often different ways of signal transmission, and the digital ultrashort wave radio station cannot be compatible with a large number of existing analog ultrashort wave radio stations. At present, without changing the existing communication equipment, it is difficult to reliably integrate the digital ultrashort wave radio station and the analog ultrashort wave radio station, and it is also difficult to realize the interconnection and...

Problems solved by technology

[0002] The radio station has a digital ultrashort wave radio station and an analog ultrashort wave radio station. According to the conditions of the communication equipment application site and the requirements of users, there are often different ways of signal transmission, and the digital ultrashort wave radio station is not compatible with a large number of existing analog ultrashort wave radio stations.

At present, without changing the existing communication equipment, it is difficult to reliably integrate the digital ultrashort wave radio station and the analog ultrashort wave radio station, and it is also difficult to realize the interconnection and intercommunication function between non-uniform wireless network stations, which leads to the flexibility of the wireless network. and reduced invulnerability
