It is the schematic diagram that the intercom system of the present invention realizes an embodiment of fault self-adapting with reference to Fig. 5.When certain intercommunication fills
It sets when breaking down, if failure talkback unit is the device of ID minimum, chooses the dress of the ID minimums after the removing failed equipment
It sets to realize audio mixing complex functionality.A certain intercom system failure, entire intercom system are adaptive:If failure intercom system be ID most
Mini system, the then device for choosing the ID minimums after removing the failed equipment are taken over the audio mixing complex functionality of the system, are initiated to it
The detection of its audio mixing field, and the media port and IP interacted with other audio mixing fields is carried, wait for that other system responses, this system execute
Intercommunication function realizes step between the network detection and system;After talkback unit 2 receives detection, silent system interconnection support intercommunication
, media channel information is changed, and enable support meeting-place again.Each network equipment distribution deployment, any network equipment failure, no
It influences other network equipments to run well, system realizes the automatic recovery after failure.
After system starts, configuration file is read, unlatching is sought to that need to monitor the network equipment, and formation is led to each network state
State table;Each autonomous system can be numbered by physics, number it is small based on;Intercommunication function is realized wherein between system, label strategy, mesh
It is preceding to use physics ID for minimum example, but the number strategy can be formulated as needed.Each network equipment starts inspection
Probing, which is sought, can carry physics number, number the audio mixing synthesis between small responsible intercom system.Once the talk back equipment failure,
The meeting of the smaller number of its intercom system identifies and accepts the audio mixing complex functionality between intercom system, which is automatically performed.
Therefore, arbitrary network equipment fault does not influence the other network equipment business of system.When physics number detect compared with skinny device it is other
When the network equipment is normal, meeting-place is added in other network equipments;Audio mixing synthesis module receives message control module control, realizes mixed
Sound and transmitting-receiving control.System media audio mixing synthesizes classification processing;Autonomous system realizes that this system audio mixing synthesizes, and system interconnection mixes
Audio mixing between the system completion system that sound synthesis is synthesized by the responsible audio mixing generated strategy synthesizes.It is not limited to traditional media collection
Middle control, this system use hierarchical control, effectively share carrying to each autonomous device, and it is independent to greatly reduce each system
The requirement of equipment media processing capacity.Talk back equipment self-organizing system is often covered, more intercom systems interconnect automatic network-building, system through interchanger
Dilatation, upgrading, forward compatibility etc. are automatically performed.Meanwhile inter-system network detects real-time, the synthesis of system failure audio mixing
Implementation strategy etc., if subsequently there is change, system changes configuration file, you can comes into force in real time.The field covered according to intercom system
Institute region, range, can independently dispose a set of or more complete equipments, and centre is interconnected using interchanger.Without any change, i.e.,
It completes system deployment and interconnects, operate quite flexible.
It is to be illustrated to the preferable implementation of the present invention, but the invention is not limited to the implementation above
Example, those skilled in the art can also make various equivalent variations or be replaced under the premise of without prejudice to spirit of that invention
It changes, these equivalent deformations or replacement are all contained in the application claim limited range.
