Passive microphone distributor, but be not limited to this；Audio signal is divided into the identical simulated audio signal of two-way by microphone distributor, and
This two-way audio signal is transferred to primary sound console and spare sound console respectively, audio signal is by primary sound console and spare
The conversion of sound console, is changed into digital audio and video signals from simulated audio signal.
Then, primary digital sound console gives audio signal transmission to primary digital audio processor, redundant digital sound console
Audio signal is also transmitted to redundant digital audio processor；Meanwhile primary digital sound console also intersected by signal processing it is standby
Alternate device gives audio signal transmission to redundant digital audio processor, and redundant digital sound console is also intersected by signal processing to be backed up
Equipment gives audio signal transmission to primary digital audio processor.So it may insure, on the one hand, sent out in a digital sound console
In the case of raw failure, still the audio signal from another digital sound console can be distributed at primary digital audio at the same time
Manage device and redundant digital audio processor；On the other hand, in the case of a digital audio processor fault, another numeral
Audio processor still can receive the audio signal of active/standby digital sound console transmission, so as to ensure audio signal still
Follow-up equipment can be transferred to.
Then, primary digital audio processor and redundant digital audio processor carries out audio signal gain, equilibrium, prolongs
When, the processing such as pressure limit, and the processing routine of primary digital audio processor and redundant digital audio processor is completely the same, processing
Audio signal afterwards is identical digital audio and video signals；Primary digital audio processor and redundant digital audio processor is defeated
The audio signal gone out continues through intersection backup network switching equipment and is transmitted.
Fig. 2A -2D are further can refer to, the intersection backup network switching equipment may include fiber optic network and interchanger system
System, the fiber optic network is dual network structure, is divided into two networks of A nets and B nets, and two networks are respectively with respective
Switch system, each switch system may include one or more interchanger；Each network is by primary digital audio processing
The equipment such as device, redundant digital audio processor, primary digital audio interface case and redundant digital audio interface case connect into planet-shaped
Connect.Audio signal simultaneous transmission after processing is given A nets and B nets two networks by primary digital audio processor, and signal passes through all the way
Cross A nets and its switch system is transferred to primary digital audio interface case and redundant digital audio interface case, another way signal warp
Cross B nets and its switch system is transferred to primary digital audio interface case and redundant digital audio interface case；Meanwhile redundant digital
Audio signal simultaneous transmission after processing is also given A nets and B nets two networks by audio processor, and wherein signal passes through A all the way
Net and its switch system are transferred to primary digital audio interface case and redundant digital audio interface case, and another way signal passes through B
Net and its switch system are transferred to primary digital audio interface case and redundant digital audio interface case.
By this way, using backup network switching equipment is intersected, by optical fiber dual network and switch system to audio
Signal is transmitted, and can obtain following three advantages：First, it may insure that a digital audio processor breaks down wherein
In the case of, another digital audio processor still can be handled and transmitted to audio signal；Second, by using optical fiber
Dual network is transmitted audio signal, it can be ensured that in the case of a failure of one network, another network still can incite somebody to action
Audio signal after digital audio processor processing carries out normal transmission；3rd, the sound after active/standby audio processor processing
Frequency signal gives primary digital audio interface case and redundant digital audio interface case by dual network simultaneous transmission, it is ensured that at it
In in the case that a digital audio interface box breaks down, another digital audio interface case still can work normally.
Finally, digital audio and video signals are converted into simulated audio signal referring still to Fig. 1, primary digital audio interface case,
And export to primary loudspeaker；Digital audio and video signals are also converted into simulated audio signal by redundant digital audio interface case, and defeated
Go out to spare loudspeaker, primary loudspeaker described here and spare loudspeaker are active loudspeaker.Meanwhile primary digital sound
Frequency interface box converts digital signals into analog signal, and intersects alternate device by audio signal transmission to master by outlet terminal
With loudspeaker and spare loudspeaker；Redundant digital audio interface case also converts digital signals into analog signal, and passes through output
Terminal intersection alternate device gives audio signal transmission to primary loudspeaker and spare loudspeaker.Thus it is possible, on the one hand, it ensure that at it
In in the case that a digital audio interface box breaks down, another digital audio interface case still carries out audio signal just
Often transmission；On the other hand, wherein in the case of a speaker malfunctions, another loudspeaker still can work normally,
Realize the normal public address of audio system.
In another embodiment, can also using digital power amplifier and the collocation mode of passive speaker, (attached drawing is not
Show) replace the collocation mode of digital audio interface case and active loudspeaker in above-described embodiment, that is, utilize two digital work(
Rate amplifier replaces primary digital audio interface case and redundant digital the audio interface case in above-described embodiment respectively, and with two
A passive speaker replaces active primary loudspeaker and spare loudspeaker in above-described embodiment respectively, can also realize same
Function and effect.The present embodiment and above-described embodiment operation principle are essentially identical, the difference is that only, are to utilize primary number
Digital audio and video signals are converted into simulated audio signal by word power amplifier, and are exported again after being amplified to simulated audio signal
To primary loudspeaker；Digital audio and video signals are converted into simulated audio signal by redundant digital power amplifier at the same time, and to simulation
Audio signal is exported to spare loudspeaker again after being amplified, wherein the primary loudspeaker and spare loudspeaker are passive
Loudspeaker.
The utility model employs two sets of digital display circuit parallel forms, and two sets of digital main preparation system equipment are just the same,
Program set it is same, so delay is consistent, it is ensured that the signal for reaching loudspeaker is completely the same, it is ensured that signal it is fully synchronized；
Transmitted using optical fiber, an optical fiber can transmit the original simulated audio signal in hundreds of tunnels, dramatically saves on cable laying
Workload, and decay during optical signal transmission and can almost ignore, greatly ensure that the transmission quality of signal；Using
Dual network framework, two digital networks are active and standby relations, while support two systems, and in active system and spare system
Set between system and intersect backup network switching equipment, often cover system can realize seamless automatic switchover on two sets of networks, when one
When a network breaks down, audio signal still can bypass trouble point and carry out normal transmission.So the utility model is than conventional
Audio system possesses the reliability and stability of higher, can adapt to various adverse circumstances and different operating conditions, even in
In the case of any one system or a network failure, the normal work of audio signal still can guarantee that.
Certainly, the utility model can also have other various embodiments, without departing substantially from the utility model spirit and its essence
In the case of, those skilled in the art work as can make various corresponding changes and deformation according to the utility model, but these
It is corresponding to change and deform the scope of the claims that all belong to appended by the utility model.
