Voice wired and wireless automatic switching device and communication method thereof

Abstract

The invention provides a voice wired and wireless automatic switching device and a communication method thereof. The switching device is connected between a wired telephone and a duplex radio station and comprises a DSP processor, an off-hook and on-hook switch, an adaptive filter, a two-wire and four-wire converter, and a telephone receiver and a telephone transmitter that are connected to the off-hook and on-hook switch; the output end of the telephone transmitter is connected with the DSP processor through a ringing detection module, the two-wire and four-wire converter is connected with the duplex radio station, the two-wire and four-wire converter and the duplex radio station are connected with the DSP processor through a DTMF detection module, and two output ends of the DSP processor are connected with the off-hook and on-hook switch and the duplex radio station respectively to control the off-hook and on-hook switch and the duplex radio station according to ringing detection signals and DTMF detection signals. The switching device is high in automation degree and convenient to operate, the noise distinguishing capability can be remarkably improved, and the overall call performance of the system is enhanced.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a voice wired and wireless automatic switching device and a talking method thereof. Background technique [0002] The voice transfer between radio stations and wired telephones is widely used in voice dispatching of seaport terminals, SSBRT services of coast stations, and voice dispatching of emergency command communications. When a ship sailing on the sea needs to contact the land, it first calls the nearby coast station, and then the coast station manually transfers the ship berth to the telephone switching network to realize the interconnection between the ship berth and the land wired telephone; emergency communication command personnel , Through the voice dispatching station, the interconnection between telephone and short wave, telephone and ultrashort wave, and short wave and ultrashort wave is realized. [0003] At present, through the voice dispatching station, t...

AI Technical Summary

Problems solved by technology

[0003] At present, through the voice dispatching station, the voice transfer between the wired telephone and the wireless station requires manual operation and an operator on duty, and the automation of voice transfer is not realized.

In addition, there are problems of low voice transfer reliability and poor communication quality during the call
