Description

A kind of PTT

Technical field

The present invention relates to communication device, relate in particular to a kind of PTT.

Background technology

Along with the reach of science progress, existing contact method is more and more diversified, the communication device that is similar to PTT is also widely used in the places such as night shift room, foreground, entrance guard chamber, room security, warning device, but existing scheme is generally and fills a phone, while making a call, need dialing, during hands-free answering, sound is not very large, can cause inconvenience running into emergency, is easily interfered yet.

Summary of the invention

For solving the problems of the technologies described above, now provide a kind of PTT of easy to use, diverse in function.

The invention provides a kind of PTT, comprise PTT housing and Push To Talk, also include and be positioned at the ptt button of PTT surface of shell, the hole that amplifies, power interface and network interface, and be positioned at loudspeaker and the microphone of PTT enclosure interior, described micropkonic sound output arranges towards the hole that amplifies, and for received audio signal and convert sound to and play; The sound input end of microphone arranges towards the hole that amplifies, for receiving sound and converting audio signal to;

Described Push To Talk comprises speech processing system and soft switch service platform, and this speech processing system is positioned at PTT housing, and speech processing system comprises coder and microprocessor,

This coder for carry out voice A/D conversion, digital signal and pcm stream bi-directional conversion and carry out the bi-directional of voice packet with microprocessor;

This microprocessor is all connected by circuit with ptt button, power interface, network interface, loudspeaker, microphone and coder, in speech processing system, play main s operation control effect, for all carrying out transmission and the conversion of signal with ptt button, power interface, network interface, loudspeaker, microphone and coder, carry out the mutual of signaling and process with soft switch service platform; Voice packet to coder is received and dispatched, and carries out the encoding and decoding of voice simultaneously, and in assistance coder, pcm stream and system can be identified the bi-directional conversion of voice;

This soft switch service platform, is connected with network interface by gateway, and by IP network Long-distance Control speech processing system, for the signaling that speech processes platform is transmitted, carries out remote interaction and control.

Further, described ptt button is arranged on the front of PTT housing; The described hole that amplifies is opened in the front of PTT housing; Described power interface is arranged on the back side of PTT housing; Described network interface is arranged on the back side of PTT housing.

Further, described Push To Talk also can be connected with public telecommunication network by soft switch service platform, realizes and outside being connected and call, and public telecommunication network can be any public communication networks such as UNICOM, movement or telecommunications.

A network interface of PTT back side of shell of the present invention is connected with soft-switch platform by gateway, and another network interface is connected with designated telephone by gateway; Power interface is connected with external power supply by power supply adaptor, for each parts of PTT housing are powered; Ptt button is connected with microprocessor.

After ptt button is pressed, signal is reached to microprocessor, microprocessor will reach designated telephone and soft switch service platform by network interface and gateway after the signal receiving and coder Combined Treatment, after designated telephone is switched on, PTT can be conversed by the microphone in housing and loud speaker and designated telephone, can ticketed call relevant information on the service platform of soft switch simultaneously; Soft switch service platform also remote controlled PTT is broadcasted by loud speaker.

A kind of PTT of the present invention is applied to night shift room, foreground, entrance guard chamber, room security, warning device etc., only needs that a key is hands-free answers or a key makes a call, and greatly facilitates operating process.

The beneficial effect having has:

1, there is call in ptt button after being pressed, after designated telephone is switched on, can not interrupt, until designated telephone is hung up, finishes call;

2, in PTT housing, there is microphone and loud speaker, direct hands-free intercommunication after connecting with designated telephone;

3, with broadcast capability, soft switch service platform is remote controlled, by PTT loud speaker, broadcasts;

4, easy to connect, PTT housing only need connect netting twine, power supply can complete interconnecting of each system of PTT;

5, PTT housing is flush type mounting structure, can imbed body of wall or inserted in table top and install, and installs hidden.
