Embodiment Construction

[0021] The following structural drawings and embodiments further illustrate the present invention.

[0022] A frequency coupling method for half-duplex radio stations with different frequencies in the air, which comprises the following steps:

[0023] First, set up a half-duplex radio station on the ground that matches the half-duplex radio station carried by the flying object, so that the airborne object that needs to talk can communicate with the radio that matches the ground power carried by it;

[0024] Secondly, connect the voice sending port and voice receiving port of the radio station set on the ground interactively, that is, connect the voice sending port of one radio station with the voice receiving port of another radio station through the radio access module (RIF) in the digital program-controlled switching host. , the voice receiving port of one radio station is connected with the voice transmitting port of another radio station, and a signal detection circuit is ...

Abstract

The invention is in use for solving issue that in procedure of antiaerial command, current voice communication system cannot generate PTT automatically to control the send receive of half duplex station, as well as issue of inconvenient use. The disclosed system includes digit program controlled main exchanger (DPCME), communication unit, A / B system switch controller, intra private line telephone, communication module of shortwave / ultrashort wave station, exterior line of telephone unit. Characters are that through the station access module in DPCME, frequency-coupling device (FCD) in DPCMEand input / output in FCD are connected to input / output in the communication module of shortwave / ultrashort wave station. The invention solves difficulties of frequency coupling.

Description

technical field [0001] The invention relates to a communication control system, in particular to a communication control system integrating various wired, wireless, full-duplex and half-duplex radio communication modes, in particular to a multi-station with frequency coupling and ground-air coupling functions Functional voice communication control system. Background technique [0002] With the development of communication technology, a single means of communication is far from meeting the needs of users. In order to achieve specific tactical goals, users hope to use multiple means of communication at the same time to carry out a wider range of communication activities. In this way, in the same command and control center It integrates wired communication, wireless communication, optical fiber communication, satellite communication and other means of communication. [0003] At present, in the process of air command, the VHF / UHF and other radio stations commonly used at home a...
