Abstract

A novel mini-type conference machine is used for remote audio conferencing and dispatching. The prior art has the disadvantages of single function, high cost and the like. A processor of the conference machine is connected with a programmable logic circuit and a switching module; the switching module is connected with a conference module, a voice recording and playing module, and the programmablelogic circuit through a PCM (pulse code modulation) wire; the conference module and the voice recording and playing module are connected with the programmable logic circuit through a control wire; theconference machine further comprises an IP module and a relay module; and the IP module and the relay module are connected with the programmable logic circuit through a control wire, with the switching module through a clock line, and with the processor through a HDLC (high - level data link control) line. The novel mini-type conference machine has the advantages that the TDM (telemetric data monitor) and IP signals can be simultaneously switched on one conference machine; the conference functions can be adjusted as needed; and the use is flexible.

Description

Novel mini-session machine

[technical field]

The utility model relates to a kind of mini-session machine, is used for remote speech meeting and scheduling.

[background technology]

Along with the development of next generation network (NGN) and meeting product, the application of teleconference more and more widely, enterprise, government and industries such as production, the energy are more and more stronger to the demand of meeting with multiple access capability and scheduling product.Existing middle-size and small-size conference facility all only has single TDM (time division multiplexing Time DivisionMultiplexer) and IP access function, satisfy to possess this two kinds of access capabilities simultaneously, just need purchase two cover conference facilities, and the cost height takes up space.

In addition, the different function of traditional conference facility need be provided with different servers, but when need realizing multiple function, just needs a plurality of servers, and is very inconvenient.

[utility model content]

In order to overcome the above-mentioned defective that exists in the prior art, the utility model provides a kind of novel mini-session machine, and is integrated by function, realizes that on a meeting machine TDM and IP insert, and by improving framework, realizes multiple function to reach a meeting machine.

For this reason, the utility model is by the following technical solutions: novel mini-session machine, comprise processor, it is characterized in that described processor is connected with Programmable Logic Device and Switching Module, Switching Module is connected with the meeting module with voice recording-reproducing assembly and pass through the PCM line and link to each other with Programmable Logic Device by PCM (pulse code modulation pulse code modulation) line, and the meeting module is passed through control line with voice recording-reproducing assembly and linked to each other with Programmable Logic Device; Described meeting machine also comprises IP module and trunk module, and the IP module links to each other with Programmable Logic Device by control line with trunk module, links to each other with Switching Module by clock line, links to each other with processor by the HDLC line.The meeting module is in order to realize conferencing function, and voice recording-reproducing assembly is in order to the recording playback voice messaging.Trunk module inserts in order to realize TDM, the IP module inserts in order to realize IP, Switching Module is responsible for the PCM time gas exchange, Programmable Logic Device can write multiple function program, CPU (processor) is responsible for the information processing and the control of entire machine, a kind of data link layer protocol that High-Level Data Link Control (HDLC) agreement is based on promotes the data that are sent to down one deck can be received exactly in transmission course, guarantees that transmission is reliable.CPU controls the work of IP module and trunk module according to ready-made program, thereby has realized inserting on a machine purpose of TDM and IP signal, has reduced cost.By loading different service routines, just can realize multiple different conferencing function, very convenient.

As the further of technique scheme improved and replenish, the utility model is taked the following technical measures or the combination in any of these measures:

Described IP module and trunk module are located at respectively on the daughter board, and described processor, Programmable Logic Device, Switching Module, meeting module and voice recording-reproducing assembly are located at motherboard, and daughter board can be connected on the motherboard with plugging.The mother baby plate design is more flexible, can insert the IP module and the trunk module daughter board of needs according to instructions for use, has realized independent assortment.On motherboard, realize resource management and main logical process, and can freely load different service routines; Daughter board is to IP and/or relaying access function in requisition for loading.

Also be provided with the DTMF module on the described motherboard, it links to each other with Switching Module by the PCM line, and links to each other with Programmable Logic Device by control line, to realize DTMF (dual-tone multifrequency Dual Tone MultiFrequency) function.

Also be provided with echo cancellation module on the described motherboard, it links to each other with Switching Module by the PCM line, and links to each other with Programmable Logic Device by control line, in order to eliminate echo.

Described Programmable Logic Device is the FPGA module.FPGA (field programmable gate array) module can be used repeatedly, is convenient to adjust function, uses flexibly.

Beneficial effect: the utility model adopts the novel product framework, has realized inserting TDM and IP signal simultaneously on a meeting machine, and can adjust conferencing function as required, uses flexibly.
