Wired/wireless automatic switching device for voice

Abstract

The invention relates to a wired / wireless automatic switching device for voice. The wired / wireless automatic switching device for the voice comprises a power circuit, an audio transmitting impedance matching circuit, an audio receiving impedance matching circuit and a transmitting control circuit, wherein the audio transmitting impedance matching circuit, the audio receiving impedance matching circuit and the transmitting control circuit are connected with the power circuit; the input end of the audio transmitting impedance matching circuit is connected with a telephone transmitter of a wired telephone, and the output end of the audio transmitting impedance matching circuit is connected with the audio interface of a radio station through an audio output port; the input end of the audio receiving impedance matching circuit is connected with the audio interface of the radio station through an audio input port, and the output end of the audio receiving impedance matching circuit is connected with the telephone transmitter of the wired telephone; the output end of the audio transmitting impedance matching circuit is also connected with the input end of the transmitting control circuit; the output end of the transmitting control circuit is connected with the audio interface of the radio station. The wired / wireless automatic switching device for the voice, disclosed by the invention, has the advantages that automatic control of voice receiving and transmitting of the wired telephone and the radio station can be effectively realized; simultaneous control can be realized on the voice communication of broadcasting stations of multiple types; the flexibility and the applicability of a dispatch and command system are improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a voice wired / wireless automatic switching device. Background technique [0002] In the command and dispatch system, wired dispatch command and radio station command are usually used, and the connection between these two types of systems usually uses computers and complex network control equipment. In emergency communication occasions, this connection method takes a long time, The connection is inconvenient, and the adaptation of audio interfaces of various types of radio stations requires separate control equipment, which is not flexible enough in centralized command and dispatch. [0003] The "voice wired / wireless adapter" with the patent number of 201220483636.2 connects the machine-communication / vehicle-communication wired control box with the wireless transmitter to realize the wired / wireless transfer control in the car, and this method is very useful for realizing...
