Abstract

The utility model discloses the fire emergence evacuation broadcast system based on CobaNet, including CobaNet broadcast hosts, switching equipment, multiple CobaNet broadcast zonal device, multiple power amplifiers and multiple loudspeakers, CobaNet broadcast zonal device is based on Corbanet connection communications by switching equipment and CobaNet broadcast hosts, CobaNet broadcast zonal devices connect one to one with power amplifier, loudspeaker connects one to one with power amplifier, multichannel sound source signal is encoded into digital audio and video signals and is respectively sent to corresponding CobaNet broadcast zonal device by CobaNet broadcast hosts.The utility model is transmitted based on CobraNet, propagation delay time can be reduced, multipath audio signal from broadcast host is corresponded to respectively and sent to different broadcast zonal devices, realizes that a broadcast host can be while different alarm voices of transmitting messages different regions, instruct evacuation.

Description

Fire emergence evacuation broadcast system based on CobraNet
Technical field
The utility model is related to broadcast technology, more particularly to the fire emergence evacuation broadcast system based on CobraNet.
Background technology
Fire emergence evacuation broadcast system is the visual plant of fire evacuation and fire fighting command, in whole fire-fighting Control management system In play extremely main effect.Existing fire emergence evacuation broadcast system is general using simulation letter in the transmission of voice signal Number, the shortcoming of analog signal be a circuit can only transmission of one line audio signal, simultaneous transmission multiple signals to be accomplished by laying A plurality of circuit, while analog signal is easily interfered the problems such as causing to produce distortion, noise;Also some producer uses Network digital signal, or but can not on the netting twine simultaneous transmission multipath audio signal, or be exactly audio signal Transmission delay is than larger, and this mode is all the customized proprietary protocol of each producer, does not possess versatility, without redundancy The mechanism of backup so that the reliability of system is had a greatly reduced quality.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide the fire-fighting emergent based on CobaNet Broadcast system, the problem of its broadcast system that can solve prior art is unable to simultaneous transmission multipath audio signal and is delayed big.
The purpose of this utility model is realized using following technical scheme:
Fire emergence evacuation broadcast system based on CobaNet, including it is CobaNet broadcast hosts, switching equipment, multiple CobaNet broadcast zonal device, multiple power amplifiers and multiple loudspeakers, CobaNet broadcast zonal devices pass through switching equipment Corbanet connection communications are based on CobaNet broadcast hosts, CobaNet broadcast zonal devices are corresponded with power amplifier to be connected Connect, loudspeaker connects one to one with power amplifier, multichannel sound source signal is encoded into DAB by CobaNet broadcast hosts Signal is respectively sent to corresponding CobaNet broadcast zonal device.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is transmitted based on CobraNet, propagation delay time can be reduced, by the MCVF multichannel voice frequency from broadcast host Signal corresponds to send to different broadcast zonal devices respectively, realizes that a broadcast host can be while transmit messages not different regions Same alarm voice, instructs evacuation.
Brief description of the drawings
Fig. 1 is the function structure chart of the fire emergence evacuation broadcast system of the present utility model based on CobaNet.
Embodiment
Below, with reference to accompanying drawing and embodiment, the utility model is described further:
Referring to Fig. 1, the fire emergence evacuation broadcast system based on CobaNet, including it is CobaNet broadcast hosts, switching equipment, many Individual CobaNet broadcast zonal device, multiple power amplifiers and multiple loudspeakers, CobaNet broadcast zonal device are set by exchanging Standby to be based on Corbanet connection communications with CobaNet broadcast hosts, CobaNet broadcast zonal devices are corresponded with power amplifier Connection, loudspeaker is connected one to one with power amplifier, and multichannel sound source signal is encoded into digital sound by CobaNet broadcast hosts Frequency signal is respectively sent to corresponding CobaNet broadcast zonal device.
CobraNet is existing network digital audio Real-time Transmission, is general technology, and transmission delay is to the maximum 5.33 milliseconds, the delay compared to other transmission equipments is small.CobraNet broadcast hosts as whole system audiogenic device, There is a situation where to need to play different voice messagings to different regions simultaneously.CobraNet broadcast hosts believe various sources of sound Number collection is come in, and is encoded into network packet, that is, digital audio and video signals according to prior art, is respectively sent to exchange and sets In standby Ethernet, a variety of digital tone source signals are converted to audio signal and are sent to corresponding power by CobraNet broadcast zonal devices Amplifier carries out power amplification, is exported eventually through loudspeaker, realizes the performance of multiple-channel output simultaneously.
It is the general network switch that switching equipment, which is selected, it uses CobraNet technologies, at present common product on the market The network switch that board producer is produced has the support technology.
Certainly, the quantity of CobraNet broadcast hosts is also not limited to one, can be two even more many, all with it is same Individual switching equipment connection, different CobraNet broadcast hosts send sound source signal to CobraNet zonal devices respectively.As prolonging Stretch, the quantity of switching equipment is also not limited to one, can be multiple, be communicated between switching equipment.It is for example current to exchange Equipment is two, two switching equipment communication with one another, and one of switching equipment is broadcasted as main switching unit and CobraNet Main frame is connected, and another switching equipment is not connected as from switching equipment with CobraNet broadcast hosts, so as to realize more many The output on road, distributed areas are more extensive.If switching equipment be three, switching equipment A as main switching unit with CobraNet broadcast hosts are connected, and switching equipment B is connected with switching equipment A, and switching equipment C can be connected with switching equipment B It can be connected with switching equipment A.Each switching equipment connects multiple CobraNet zonal devices respectively again.
The utility model is transmitted based on CobraNet, propagation delay time can be reduced, by the MCVF multichannel voice frequency from broadcast host Signal corresponds to send to different broadcast zonal devices respectively, realizes that a broadcast host can be while transmit messages not different regions Same alarm voice, instructs evacuation.
It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various It is corresponding to change and deformation, and all these change and deformation should all belong to the protection of the utility model claim Within the scope of.

Claims (1)

1. the fire emergence evacuation broadcast system based on CobaNet, it is characterised in that including CobaNet broadcast hosts, switching equipment, Multiple CobaNet broadcast zonal devices, multiple power amplifiers and multiple loudspeakers, CobaNet broadcast zonal device is by exchanging Equipment and CobaNet broadcast hosts are based on Corbanet connection communications, a pair of CobaNet broadcast zonal devices and power amplifier 1 It should connect, loudspeaker connects one to one with power amplifier, multichannel sound source signal is encoded into numeral by CobaNet broadcast hosts Audio signal is respectively sent to corresponding CobaNet broadcast zonal device.
