Method and device for communicating telephone system and talkback dispatching system

Abstract

The invention relates to the technical field of voice communication, and discloses a method and device for communicating a telephone system and a talkback dispatching system. According to the method, switching control of off-hook, on-hook and communication is achieved through an automatic recognition, detection and judgment circuit. A communication device comprises a telephone system interface, a matching circuit, a talkback dispatching system interface, a ring detection circuit and a single-chip microcomputer controller. The telephone system interface is connected with the talkback dispatching system interface through the matching circuit, the ring signal end of the telephone system interface is connected with the single-chip microcomputer controller through the ring detection circuit, the first output end of the single-chip microcomputer controller is connected with the input end of the matching circuit, and the second output end of the single-chip microcomputer controller is connected with the input end of the talkback dispatching system interface circuit. According to the method and device, a dial tone signal and an on-hook signal from the telephone system can be automatically recognized, connection and voice communication between a telephone user and a talkback dispatching system user are achieved, and an external power supply is not needed for power supply.

Description

[0001] technical field [0002] The invention relates to the technical field of voice communication, in particular to a method and a device for communicating a telephone system with an intercom dispatching system. Background technique [0003] At present, the known technology and device for voice communication between the telephone system and the intercom dispatching system are very complicated, the equipment is huge, and the technical requirements for use and maintenance are relatively high.
