Fig. 1-4 is please referred to, to achieve the above object, the invention provides the following technical scheme: a kind of fax turns the logical of intercommunication
News system includes two multi-path voice convergence platforms, FXO interface, PSTN network and more intercommunication audio transmission lines；
Wherein, PSTN network is Public Switched Telephone Network；Intercommunication audio transmission line is used for the intercom of user and more
It is attached between audio interface in the voice convergence platform of road；Medium of the FXO interface as voice communication, passes through the side of dialing
Two multi-path voice convergence platforms are established call connection in different zones by formula；Multi-path voice convergence platform by FXO interface with
PSTN network connection；
The multi-path voice convergence platform, including touch display screen, pcm bus, 1 road FXO interface, 4 tunnel audio interface,
CPU, OCR identification module, TTS voice synthetic module, dial system；
CPU, for handling all business and logic in multi-path voice convergence platform, by the business of whole system with orderliness
Change, the form of automation is presented to user.
Touch display screen is the medium as human-computer interaction, important and executable content is shown to user, next makes
User can also be inputted operational order or step by touch display screen, and every configuration parameter is arranged, so that platform is by having to
It asks or condition executes the operational order inputted.
OCR identification module is for character image to be identified as machine language known to computer；
TTS voice synthetic module will be for that will be converted to analog voice by the switched machine language of OCR identification module, i.e., most
User is played in the form of analog voice and is distinguished eventually listens.
Wherein, dial system is contacted for will establish between different multi-path voice convergence platforms, in each multi-path voice
It is integrated with dial key and Answer Key in convergence platform, a multi-path voice convergence platform in strange land is connected to by way of dialing,
So that establishing connection between two multi-path voice convergence platforms in different geographic regions；
All analog voice signals of the external 4 tunnel audio interface of multi-path voice convergence platform can be passed through volume by pcm bus
Code mode is transmitted to CPU, then leads to useful electric signal transmission to corresponding audio interface via the business logic processing of CPU
Decoded form is crossed, then simulation language is converted by voice signal and plays to user；
Wherein, due to including that signals, the useful signals such as noise refer to the signal containing audio data in electric signal；Tool
Body can carry out what internal identification judged by way of existing software；
Wherein, 4 tunnel audio interface are interacted by pcm bus and CPU, can be had between 4 tunnel audio interface to realize
The communication of selectivity.
Wherein, the FXO interface is as physical interface, for connecting outside line, passes through multi-path voice convergence platform itself
Dial system is realized and extraneous terminal called.
As multi-path voice convergence platform, which can make to connect by its included touch display screen
The source of sound entered carries out the addition and delete operation of conference group, which could support up connecing for 4 road voice signals
Enter, as shown in Figure 1, it is known that the intercom of tetra- different frequency ranges of a, b, c, d passes through intercommunication audio transmission line respectively and butts up against multichannel
1st, 2,3,4 tunnel of voice convergence platform, before un-activation human-computer interaction interface, A1 and a, B1 and b, C1 and c, D1 and d can
Realize speech talkback, and A1, B1, C1, D1 can not achieve interactive voice two-by-two, it is man-machine in activation (wake-up) referring to the process of Fig. 2
4 groups of intercommunications are added to after same conference group mode, it can be achieved that A1, B1, C1, D1 voice intercommunication, to reach by interactive interface
The function of multi-path voice fusion, easy to operate, logic is simple, is suitble to relevant industries emergency operation；
As trans-regional multi-path voice convergence platform, as shown in the a-quadrant of Fig. 3, it is known that pair of two different frequency ranges of a, b
Say that machine passes through the 1st road and the 3rd tunnel that intercommunication audio transmission line butts up against multi-path voice convergence platform, A1, A2 respectively, a can be realized
Speech talkback, A3, A4, b can realize speech talkback, and because of A1, A3 not cannot achieve intercommunication in same frequency point, be melted using multi-path voice
Platform conferencing function is closed, a, two groups of intercoms of b can be added to conference group mode, realizes a, (i.e. language is mutual for b voice data exchange
It is logical), A1, A2, A3 are realized with this, the direct intercommunication between A4；
Wherein, conference group mode refers to: the member in all addition groups each may participate in speech talkback and receive in group
The voice of other members.
It is equipped with OCR identification module and TTS voice synthetic module inside every multi-path voice convergence platform, is melted in multi-path voice
After closing detection of platform scan text, it is converted into image format, using the character recognition technology of OCR identification module, is converted into inside
For the text of storage, the text-to-speech synthetic technology of TTS voice synthetic module is further utilized, turns the text of storage inside
It changes voice signal into, is transmitted by pcm bus, and main control chip CPU interactive information, further, by operating touch display screen,
Fax and extraneous source of sound are held in same meeting-place, then can be achieved to be transmitted to connected pair via the voice signal of fax conversion
Say machine.
Specifically, a kind of fax turns the realization of the voice communication system of 350M intercommunication in the embodiment of the present invention, firstly, passing through
Touch screen configuration interface pulls in the fax source of sound of B area and external source of sound in same conference group mode；Then according to Fig. 3 and figure
Shown in 4, voice is established by the voice converged communication system of dialing form and B area by the multi-path voice convergence platform of a-quadrant
Access；Secondly, the multi-path voice convergence platform of a-quadrant detects scan text, by OCR and TTS technology, by the text after conversion
Voice messaging reaches the multi-path voice convergence platform of B area by PSTN；B area multi-path voice convergence platform is received from A
The voice signal in region then reaches voice signal because fax voice signal has been in same meeting field mode with external source of sound
The intercom being connected with multi-path voice convergence platform, the characteristic propagated using the same frequency point voice of intercom, realizes B1, B2,
B3, B4 play the mode of the fax text from a-quadrant.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
Benefit requires rather than above description limits, it is intended that all by what is fallen within the meaning and scope of the equivalent elements of the claims
Variation is included within the present invention.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
The other embodiments being understood that.
