Abstract
The invention provides a multi-screen interactive call control method, a master device and a control system. The method comprises the following steps: the master device allocates multicast addresses for a plurality of slave devices; the master device receives a call request of an external device and sends a call multicast command to the slave devices corresponding to the multicast addresses to instruct the slave devices; and when receiving an answered signal sent by the answering slave device, the master device sends a hang-up multicast command to the slave devices to instruct the non-answering slave devices to hang up a call of the external device. The method simplifies the process of communication between the master device and the slave devices, effectively improves the communication speed, and accordingly, significantly improves the reliability.
Description
Technical field
The present invention relates to field of wireless communication, relate in particular to a kind of multi-screen interactive call control method, main equipment and control system.
Background technology
At present the multi-screen intercom system of intelligent building, is made up of a main equipment and multiple subset conventionally, and main equipment is in charge of the state switching of system etc., and subset is generally the extension set, mobile phone, panel computer, TV etc. with call function.In the time using external equipment to call out this intercom system, all master and slave equipment all shows external video, and after a subset is answered therein, remaining equipment need be hung up outside video.
Conventionally adopt the mode of clean culture, for each subset default address respectively, main equipment is preserved the address of all subsets, one of them subset is answered rear notice main equipment, main equipment need send ath command one by one according to the address of subset, after a subset interaction success, carry out successively again the mutual of next subset, until hang up all subsets, if when the subset in system is more, such mode communication speed can be very slow, communication also increases the error rate often simultaneously, in addition, in the time that new subset adds system, main equipment can not be confirmed quantity and the address that new equipment is, cannot realize the interaction with new equipment.

Embodiment
Embodiments of the invention are described with reference to the accompanying drawings.The element of describing in an accompanying drawing of the present invention or a kind of execution mode and feature can combine with element and feature shown in one or more other accompanying drawings or execution mode.It should be noted that in order to know object, in accompanying drawing and explanation, omitted expression and the description of unrelated to the invention, parts known to persons of ordinary skill in the art and processing.
Multi-screen interactive call control method embodiment:
As shown in Figure 1, a kind of multi-screen interactive call control method, comprising:
Step S101, main equipment is that multiple subsets distribute multicast address;
Step S102, main equipment receives the call request of external equipment, sends and calls out ordered multicast, to indicate each subset to the subset corresponding with multicast address;
Step S103, main equipment receive answer that subset sends answer signal time, send and hang up ordered multicast to each subset, to indicate non-calling of answering subset and hang up described external equipment; Wherein: answer subset and be and arbitraryly in described multiple subset answer the subset that described external equipment is called out, non-answer subset be in multiple subsets except described in answer other the arbitrary subsets subset.
Particularly, main equipment is server, subset is the communication apparatus that the mobile phone, computer, panel computer, intelligent television of family etc. has display screen, and main equipment is that subsets all in system distributes multicast address, and all subsets have same IP address.
When external equipment is called out subset, main equipment receives this call request, and send and call out ordered multicast to all subsets according to multicast address, inform that subset now has external equipment to call out, all subsets are being received after this calling ordered multicast at demonstration screen display external call request picture.
External equipment can be the intercom on entrance, or mobile phone, computer, panel computer, extension set etc. have the communication apparatus of display screen.
Now main equipment wait subset is answered.
After one of them subset is answered, this is answered one of subset transmission and has answered signal to main equipment, main equipment receives this and has answered after signal and send and hang up ordered multicast to all subsets, the non-subset of answering receives after hanging up ordered multicast and stops showing external call request picture, answers subset and receives after this hangs up ordered multicast and ignore this order.
Main equipment receives answers answering after signal that subset sends, answers subset described in control and sets up communication with external equipment and is connected, answers afterwards subset and can converse with external equipment, answers the subset demonstration video of conversing.
If do not have subset to answer in Preset Time, main equipment does not receive and has answered signal in Preset Time, and the calling of external equipment is hung up in main equipment control, and subset stops showing external call request picture.
If need to add new subset, main equipment is that the subset newly increasing distributes multicast address, and by this multicast address, main equipment can be identified this subset newly increasing.
The multi-screen interactive call control method that the present embodiment provides, by the mode of multicast, main equipment is that subset distributes multicast address, and send ordered multicast subset is controlled, simplify the communication flow between main equipment and subset, effectively improve communication speed, corresponding reliability also significantly improves.
Main equipment embodiment:
As shown in Figure 2, a kind of main equipment, comprising:
Address assignment module 201, is used to multiple subsets to distribute multicast address;
Signal receiving module 202, answers signal for what receive the call request that external equipment sends and receive that subset sends;
Order sending module 203, for receive answer subset send answer signal time, send and hang up ordered multicast to each non-subset of answering, and receive answer that subset sends answer signal time, send and hang up ordered multicast to each non-subset of answering.
Multi-screen interactive call control system embodiment:
As shown in Figure 3, multi-screen interactive call control system, comprising:
Main equipment 301 and multiple subset 302, multiple subsets 302 are connected with main equipment 301, and subset 302 is for answering the calling of external equipment 203.
Particularly, main equipment 301 is server, comprising:
