Abstract
The utility model discloses a network calling broadcast system comprises an IP network broadcast control terminal, a switch, and a digital broadcast terminal which are connected successively. The switch is connected with a work station. The digital broadcast terminal is connected with multiple indoor loudspeaker boxes and outdoor loudspeaker boxes. The IP network broadcast control terminal is connected with a telephone interface. By the above structure, a calling system and a broadcast system are combined so as to achieve block general calling of broadcast calling. In addition, the broadcast system is comprehensively compatible with analog sound sources.
Description
Technical field
The utility model relates to calling system, is specifically related to the calling network broadcast system.
Background technology
STD-400/56D series digit different telephone exchanges for electric power dispatching main frame adopts full decentralized control and switching technology, tandem main system, user subsystem, communication subsystem, consists of.The tandem main system provides 24 2M nonblocking switchings, supports DP, DTMF, MFC, EM, R2, EBR2, China No. 1, No. 7 (TUP/ISUP), Q, DSS1 and our company's dedicated signalings; Tandem main system and user subsystem combination reach the total system of 2000 ports+16 2M, support the remote end module application; User subsystem also can maximum 4 autonomous systems that are combined into 512 ports+8 2M; Communication subsystem turns RS422/485 protection interface, 1 RS232 modulation modulator-demodulator interface for tandem main system, user subsystem provide two-way-48V direct current supply and 4 RS232.Can use calling system in this system, but this calling system can't carry out combination with broadcast system, broadcast ﹠ call can not realize that district's group generally calls, simultaneously the broadcast call system compatible source of sound of simulating comprehensively.
The utility model content
The utility model has overcome the deficiencies in the prior art, and the calling network broadcast system is provided, and calling system and broadcast system are combined, and realizes that district's group of broadcast ﹠ call is generally called, and can be the comprehensively compatible simulation source of sound of broadcast system.
For solving above-mentioned technical problem, the utility model is by the following technical solutions: the calling network broadcast system, comprise the IP network Broadcasting Control terminal, switch and the digital broadcast terminal that connect successively, connect work station on described switch, connect many indoor audio amplifiers and outdoor loudspeaker box on described digital broadcast terminal, described IP network Broadcasting Control terminal connects telephony interface.
Further, also connect microphone, MP3 player, DVD and numerical control radio on described IP network Broadcasting Control terminal.
Further, also be connected the level pressure power amplifying device between described digital broadcast terminal and outdoor loudspeaker box.
Further, described work station comprises leading position station and department station.
Further, described leading position station comprises computer terminal and microphone, and the department station comprises computer terminal.
Further, many indoor audio amplifiers are connected in parallel on digital broadcast terminal.
Further, many outdoor loudspeaker boxes are connected in series.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model combines calling system and broadcast system, realizes that district's group of broadcast ﹠ call is generally called, and also can realize digital Real Time Monitoring, fixed time broadcast and fire-fighting, manual emergency broadcasting etc., and function is more comprehensive.
2, broadcast calls system of the present utility model has realized number format voice applications, the application of network audio resource and comprehensive compatible simulation source of sound.
Description of drawings
Fig. 1 is theory diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated, embodiment of the present utility model is not limited to this.
Embodiment:
As shown in Figure 1, the utility model comprises IP network Broadcasting Control terminal, switch and the digital broadcast terminal that connects successively, connects work station on described switch, and work station comprises leading position station and department station.Leading position station wherein comprises computer terminal and microphone, and the department station comprises computer terminal.Connect many indoor audio amplifiers and outdoor loudspeaker box on the digital broadcast terminal of the present embodiment, many indoor audio amplifiers are connected in parallel on digital broadcast terminal, and many outdoor loudspeaker boxes are connected in series.Wherein also be connected the level pressure power amplifying device between digital broadcast terminal and outdoor loudspeaker box.The IP network Broadcasting Control terminal of the present embodiment connects telephony interface, also connects microphone, MP3 player, DVD and numerical control radio on IP network Broadcasting Control terminal.
Be connected by switch between digital broadcast terminal, IP network Broadcasting Control terminal and workbench, realized the combination of calling system and broadcast system, broadcast ﹠ call have realized that district's group generally calls, also can carry out timing and in real time digital to broadcasting simultaneously, run into emergency and also can carry out manual emergency broadcasting, function is more powerful, and the content of broadcast calls system, space and function all effectively improve.
Just can realize this utility model as mentioned above.
