Utility model content
For above-mentioned technical problem, the purpose of this utility model is to provide a kind of digital conference system, its problem that can solve robustness difference.
For achieving the above object, the technical scheme that the utility model is used is as follows:
A kind of digital conference system, it includes server, multiple three port connection modules and multiple microphone, multiple three port connection modules are sequentially connected with, and one of them port being in three port connection modules of first place is connected with the first passage of server, one of them port of the three port connection modules being in position, end is connected with the second channel of server, each microphone connects with corresponding three port connection module, further, each microphone is all connected with first passage and the second channel of server by three corresponding port connection modules.
Preferably, described server also includes wireless communication module, host CPU, main frame DSP, power amplifier module and RS485 interface, wireless communication module, main frame DSP and RS485 interface are all connected with host CPU, wireless communication module is also connected with main frame DSP, power amplifier module is connected with main frame DSP, RS485 interface is for being connected with computer by an interface convertor, power amplifier module is for being connected with audio amplifier, first passage and the second channel of server are all connected with host CPU, the first passage of server and second channel are the most all connected with main frame DSP, wireless communication module is for being connected with mobile terminal.
Preferably, one or both during described wireless communication module includes WIFI module and bluetooth module.
Preferably, described microphone includes connection jaws, microphone CPU, microphone DSP, audio output interface and pick-up head, audio output interface and pick-up head are connected with microphone DSP, and microphone DSP is connected with connection jaws by microphone CPU, and connection jaws is for being connected with three port connection modules.
Preferably, described three port connection modules are RJ45 tri-port connection module.
Preferably, one or more during described mobile terminal includes panel computer, smart mobile phone, PDA.
Compared to existing technology, the beneficial effects of the utility model are:
1
, three port connection modules simultaneously have input and output function, microphone utilizes this module to be connected to server from both direction, and microphone need not form loop and could normally use, i.e. the cable in only one of which direction just can normally use with the first passage of server or second channel UNICOM；Whether server can disconnect with measure loop, without disconnecting, microphone only need to perform the instruction that first passage sends, now second channel plays the effect that detection loop is unimpeded, disconnecting if circuit has, server can indicate first passage and second channel to control the microphone connected on its interfaces respectively, microphone will not quit work because circuit disconnects, and robustness is good.
2
, can pass through host CPU, main frame DSP, microphone CPU, the cooperation of microphone end DSP, produce the effect (each microphone is separately provided the audio effect processing such as volume, EQ, pressure limit, gain, feedback inhibition, echo cancellor) individually controlling each microphone audio；The contingent behavior prejudicial to other functions of the equipments of each microphone (after such as avoiding microphone to receive the sound wave that intensity is too high, produce suddenly and affect the high-intensity currrent of system stability) can also be limited so that whole system can controlled, robustness good.
Accompanying drawing explanation
Fig. 1 is the structural representation of the digital conference system of the utility model preferred embodiment；
Fig. 2 is the structural representation of the server in Fig. 1；
Fig. 3 is the structural representation of the microphone in Fig. 1.
Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, the utility model is described further:
See shown in Fig. 1 to Fig. 3, a kind of digital conference system, it includes server, multiple three port connection modules and multiple microphone, multiple three port connection modules are sequentially connected with, and one of them port being in three port connection modules of first place is connected with the first passage of server, one of them port of the three port connection modules being in position, end is connected with the second channel of server, each microphone connects with corresponding three port connection module, and, each microphone is all connected with first passage and the second channel of server by three corresponding port connection modules, so that microphone forms annular and is connected with server, once break down in certain microphone or junction, the normal work of whole digital conference system is not interfered with yet.
