Illustrate that distributed intercommunication provided by the utility model relays the application method of overlay device with reference to Fig. 1-Fig. 3,
It mainly includes the following steps that：
The first step, an intercom in Fig. 1 initiate caller as calling hand platform 10, at this time 31 He of gateway in a-quadrant
Ring exchanger 41 is used as host, calls the reception ride 21 in 10 corresponding region A of hand platform in apparatus and is responded by antenna feeder
Then intercom calls receive ride 21 and send voice call signal to gateway 31 by I/O port, and ask to gateway 31 be currently
System voice channel state.Caller is initiated if it is the intercom within the scope of host equipment then directly to be responded according to channel status
And PTT signals, voice data are exported by I/O port and forward digital voice data in network.If it is within the scope of slave devices
Intercom initiate caller then first by gateway 32/33 by network can be to 31 channel request of host gateway.
It should be noted that this step further include gateway device start when pattern configurations, than gateway 32 as shown in Figure 1,
Gateway 33 is slave, and gateway 31 is host.Slave must specifically include first to host registration：After slave electrifying startup, first according to net
Local profile automatic configuration parameter in pass, and from the host in trend local file report oneself IP address and
Port information；After host electrifying startup, and first according to the local profile automatic configuration parameter in gateway, then wait for from
Machine reports IP and port information.
Host side flow is as follows at this time：If there is slave is applied for registration of, then host registers map tables and establishes the heart with slave
It jumps；Network map tables are issued to all online slaves by network if network map tables have update.
It is as follows from generator terminal flow：Receiving the slave chances of update map tables, to establish voice with other slaves automatically according to map tables logical
Letter connection and heartbeat.
Second step：Host receives the call request from 10 corresponding gateway device 31 of caller hand platform, determines current speech
Channel clear, and to 10 corresponding gateway device of caller hand platform, 31 fed-back channel status.If channel idle at this time permits
Perhaps voice forwards, and the order for preparing to receive remote speech is issued to all online slaves.If channel busy, ignores this and set
Standby request.
Third walks：Slave receiving host feedback channel status, if the state fed back at this time be free time, to it is all
Line gateway device sends voice data, and local voice playback data；If the state fed back at this time is busy, ignore this
Request.
4th step：Caller hand platform 10 can freely be conversed, and reception hand platform 60, which is in, passively receives state, and can not interrupt and work as
Preceding voice communication.Time-out 1 minute, automatic hand-up calling gateway equipment if caller hand platform 10 is conversed.
5th step：After the 10 active on-hook of caller hand platform, then voice channel is discharged to host application.
6th step：After host receives the order of the request release voice channel of caller hand platform 10, responds and reset current speech
Channel status, and sent to all online slaves and terminate to receive voice command.
7th step：Slave receives voice command, and stops receiving remote speech and local forwarding.
Fig. 4 is the application signal that overlay device is relayed according to the distributed intercommunication of a preferred embodiment of the utility model
Scheming, deployment six complete equipment 1-500 in interval in a certain tunnel form looped network between equipment and equipment by ring exchanger 40, and
Linear interval 3km is distributed in tunnel.By the ride in device be arranged each equipment wireless coverage radius be 3km (
That is intercom initiates caller within the 3km of this equipment, equipment is can be with normal response), the reception in all devices
The receives frequency of ride is consistent；The tranmitting frequency for emitting ride is consistent.And the intercom receives frequency used in system with it is all
The tranmitting frequency of ride is consistent；The tranmitting frequency of intercom is consistent with the receives frequency of all rides.Therefore, entire tunnel area
It is system coverage area (using air line distance as reference), since system equipment is same frequency covering and non-blind area, then covers
Any position caller of the arbitrary intercom in its coverage area must have equipment that can respond in range, quite convenient for construction organization
Operation.
Distribution intercommunication provided by the utility model relays overlay device, converted, encoded by a series of response, A/D,
Be packaged etc. programs come handle receive ride output voice signal, and by voice data locally transmitting ride carry out playback and
It is transmitted in looped network, then the gateway in reception state is again via opposite a succession of program in looped network, by voice data
It is reduced into original voice signal and exports and give transmitting ride.The device may be implemented to appoint in the wireless coverage of its determination
It is unique that meaning intercom initiates right of speech when caller at any time；The looped network formula interconnection in the system ovelay range of its composition of principal and subordinate's machine equipment is mutual
Logical function.Site environment is disposed by utility model device, the distribution being particularly suitable under particular job environment is right
Say relaying covering service.
The distributed intercommunication of the utility model relays overlay device, since compared with traditional intercommunication network, distribution is right
Say that relay coverage system is the network of an opposing open formula, distributed TKT talkie trunk covering system can not only save network
Resource and operation cost and it can realize a wide range of, intercommunication function and remote monitoring function in real time at a distance.
Above-described, the only preferred embodiment of the utility model is not intended to limit the scope of the utility model, this
Above-described embodiment of utility model can also make a variety of changes.I.e. every claims according to the present utility model application and
Simple, equivalent changes and modifications, fall within the claims of the utility model patent made by description.This
The not detailed description of utility model is routine techniques content.
