Abstract
The utility model provides a multimedia network broadcasting system. The multimedia network broadcasting system comprises an audio input module and a microphone input module, and further comprises a central processing unit, a storage module, the microphone input module and two audio output modules. The central processing unit is respectively connected with the microphone input module, the storage module and the two audio output modules, and the two audio output modules are connected to an audio partition module through a power amplifier for output in partitions. By means of the multimedia network broadcasting system, in an area covered by a local area network, existing local area network (LAN) resources and personal computer (PC) resources are utilized to carry out one-to-many and many-to-many centralized management and interaction, the central processing unit is used to reasonably distribute audio signals according to needs, and broadcasting can be carried out in partitions according to actual needs.
Description
Technical field
This novel communication broadcast world that relates to refers to a kind of broadcasting integrated system of networking especially.
Background technology
Existing Public Address system is in various public places; For example plant area of factory, dining room, garden; Ground such as market school all are widely used, and it has developed into from the broadcast system of simply being made up of microphone, power amplifier has multi-functional integrated Public Address system.Yet when users were fixed in the equal centralization of each equipment in the system among machine room or the gatekeeper, it is more loaded down with trivial details that its operation becomes, and system is provided with complicacy, and its operation, setting, monitoring all need staff in machine room, to carry out, and maintenance brings inconvenience.
Summary of the invention
The utility model purpose is to abandon the shortcoming of prior art, and a kind of Web broadcast system that uses local area network (LAN) control and be provided with is provided, and can carry out the broadcasting of multi-region simultaneously.
For solving the problems of the technologies described above, the technical scheme of this novel employing is following:
Construct a kind of multimedia network broadcasting system, comprise audio frequency input module, microphone input module, also comprise center processing unit, memory module, microphone output module and two audio frequency output modules; Described center processing unit is connected with microphone input module, memory module, microphone output module, two described audio frequency output modules respectively, and two audio frequency output modules are connected to the audio frequency division module through power amplifier and carry out subregion output.
Further, described center processing unit is connected with telephony interface module, PORT COM module, and an end of described PORT COM module is connected with center processing unit, and the other end links to each other with local area network (LAN) or PC, can realize the multimedia broadcasting of networking.
This novel beneficial effect is: can in the scope that local area network (LAN) covers, utilize existing Internet resources LAN LAN and PC resource to carry out centralized management, the interaction of one-to-many, multi-to-multi; Use center processing unit that audio frequency is carried out reasonable distribution according to its needs, the actual needs of broadcasting is carried out subregion play.
Description of drawings
Fig. 1 is this novel structural representation.
Embodiment
Further detail originally novel below in conjunction with accompanying drawing and specific embodiment.
As shown in Figure 1; It has disclosed the concrete structure of this novel preferred embodiment; A kind of multimedia network broadcasting system comprises audio frequency input module, microphone input module, also comprises center processing unit, memory module, microphone output module and two audio frequency output modules; Described center processing unit is connected with microphone input module, memory module, microphone output module, two described audio frequency output modules respectively, and two audio frequency output modules are connected to the audio frequency division module through power amplifier, carry out the output of a plurality of subregions.System also comprises control input module and control output module; The control input module is connected center processing unit respectively with the control output module; Described control input module receives control signal, transfers serial signal to through center processing unit and delivers on the signal bus and output to the control output module.
Further, described center processing unit is connected with telephony interface module, PORT COM module, and an end of described PORT COM module is connected with center processing unit, and the other end links to each other with local area network (LAN) or PC, can realize the multimedia broadcasting of networking.Thereby described PORT COM module can connect HUB and get into local area network (LAN) and connect each computer in this local area network (LAN), commence operation, action such as keeps watch on, is provided with.
The above; It only is this novel preferred embodiment; Be not that novel technical scope is done any restriction; So this novel technical spirit of every foundation all still belongs in the scope that originally is equal to the utility model technical scheme any trickle modification, equivalent variations and modification that above embodiment did.
Claims (2)
