Embodiment Construction

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

[0022] A frequency coupling method for half-duplex stations of different frequencies in the air, comprising the following steps:

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

[0024] Secondly, connect the voice sending port and the voice receiving port of the station set on the ground interactively, that is, connect the voice sending port of one station with the voice receiving port of another 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 sending port of another radio station, and a signal detection circuit is set at the voice receiving port...

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 DPCME and 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 present invention relates to a communication control system, especially a communication control system integrating various wired, wireless, full-duplex and half-duplex radio communication modes, specifically a multi-communication system with frequency coupling and ground-air coupling functions Function 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 Concentrated wired communication, wireless communication, optical fiber communication, satellite communication and other means of communication. [0003] At present, in the process of commanding the air, VHF / UHF and other stations commonly used at h...
