Abstract

A multi-zone broadcasting system comprises a total control center (1) which controls a total broadcasting center (2), and the total broadcasting center (2) is connected with a total broadcasting network switch (3). The total broadcasting network switch (3) controls a total broadcasting network device (4) and is connected with not less than one branch broadcasting network switch (5), each branch broadcasting network switch (5) is controlled by a branch broadcasting center (6) and is equipped with a branch broadcasting device (7), and the branch broadcasting network switches (5) are linked with each other. The multi-zone broadcasting system provided by the utility model can be controlled by the total control center, and also can work regionally and independently, can broadcast in a super large zone orientation and only at a certain part of the zone, and enables the workloads of a lot of loudspeaker terminals and other broadcasting equipment in the super large zone to be improved.

Description

A kind of multizone broadcast system

Technical field

The utility model belongs to the building intelligent equipment technical field, specifically just relates to a kind of multizone broadcast system, especially relates to and can meet the multizone broadcast system of working simultaneously or working alone.

Background technology

Along with economic fast development, realize that in modern heavy construction intelligent control is the important composition mode of the modern life, the intelligent building system is exactly to realize the intelligent importance of controlling of life, Ground Connection in Intelligent Building is defined as: the COMPREHENSIVE CALCULATING machine, the state-of-the-art technology of the aspects such as information communication, make the electric power in building, air-conditioning, illumination, take precautions against natural calamities, antitheft, the co-ordinations such as transporting equipment, realize building automation (BA), communication automation system (CA), office automation (OA), security automated system (SAS) and automatic fire fighting system (FAS), the building that these 5 kinds of functions are combined is built also referred to as 5A, additional structured cabling system (SCS), structured generalization network system (SNS), intelligent building generalized information management automated system (MAS) forms, it is exactly Ground Connection in Intelligent Building.Summarize and say, intelligent building is exactly to adopt computer technology automatically to control the equipment in building, and information resources are managed, and for the user provides information service, it is that Building technology adapts to the information-based crystallization required of modern society.The intellectuality of building construction is controlled the fast development that is accompanied by the modern the Internet technology and is rapidly developed, it has gathered the set of the communication technology, automated control technology, internet technique, greatly facilitate daily life, the intelligent building technology is risen in the America and Europe, in recent years along with the fast development of China's economy, the intelligent building technology is used widely in the buildings such as government, hospital, school.

Modern large scale business center usually has square, perhaps each floor of building need to also have broadcast system for what lie fallow, no matter in outdoor square or building, existing broadcast system is all often controlled by a set of control system, can only accept the control of same set of network system, can't complete broadcast capability in the independent partitions territory, this just can't first realize that certain zonule, Zhi Xuzai square or this touch the floor possibility of broadcast separately.

The utility model content

Can only accept the control of same set of network system for existing square or building broadcast system, can't complete wide multicast function Den technological deficiency in the independent partitions territory, the utility model provides a kind of multizone broadcast system, can be subject to the control in mster-control centre, also separated regions works alone, and meets in the super large zone live load of a large amount of loudspeaker terminals and other broadcasting equipments.

Technical scheme

In order to realize above-mentioned technical purpose, the utility model designs a kind of multizone broadcast system, it is characterized in that: it comprises mster-control centre, described mster-control centre controls total broadcasting center, total broadcasting center is connected with total radio network switch, total total radio network equipment of radio network Switch control, described total radio network switch is connected with and is no less than a minute radio network switch, within described minute, the radio network switch is controlled by a minute broadcasting center, divide the radio network switch to be connected with a minute broadcasting equipment, mutual UNICOM between a minute radio network switch changes.

Within described minute, broadcasting equipment comprises transceiver apparatus and loud speaker.

Beneficial effect

A kind of multizone broadcast system that the utility model provides, can be subject to the control in mster-control centre, also separated regions works alone, can the broadcast in orientation, super large zone need, also can be just in zone certain part broadcasted, improved the live load of a large amount of loudspeaker terminals and other broadcasting equipments in the super large zone.

The accompanying drawing explanation

Accompanying drawing 1 is connection diagram of the present utility model.

Embodiment

Below in conjunction with drawings and Examples, the utility model is described further.

Embodiment

As shown in Figure 1, a kind of multizone broadcast system, it is characterized in that: it comprises mster-control centre 1, described mster-control centre 1 controls total broadcasting center 2, total broadcasting center 2 is connected with total radio network switch 3, total radio network switch 3 is controlled total radio network equipment 4, described total radio network switch 3 is connected with and is no less than a minute radio network switch 5, within described minute, radio network switch 5 is controlled by minute broadcasting center 6, divide radio network switch 5 to be connected with minute broadcasting equipment 7, mutual UNICOM between a minute radio network switch 5 changes.

Within described minute, broadcasting equipment 7 comprises transceiver apparatus and loud speaker.

Claims
