The following detailed description of the implementation principle of the system of the present invention is made with reference to the accompanying drawings:
the invention aims to provide a visual talkback paging system without a server, which can carry out talkback and paging under the condition of not configuring the server. Because the system does not need to be configured with a server, the system cost is greatly reduced; the terminal configuration parameters are very simple and can be used only by configuring the terminal IP; the data flow is directly sent regardless of talkback or paging, and the data flow is not influenced by other data flows, so that the stability is higher; if the number of the terminals is required to be expanded, the terminals can be used by directly accessing a network, so that the method is very convenient and has strong expansibility.
As shown in fig. 1, the whole system has only two terminal types: a pager and a talkback terminal. The paging devices can directly communicate with each other, communicate with the terminals directly, and perform paging operation on a plurality of terminals. The talkback operation can be directly carried out between the terminals.
In the system, the pager plays the original role of a server and is responsible for searching and displaying the terminal, and fig. 2 shows the whole process of searching and displaying the terminal by the pager. Firstly, the pager firstly multicasts and sends a search command, the terminal which joins in the multicast before receives the search command, then the terminal sends out the terminal state, after the pager receives the terminal state, the pager stores the terminal information, and then the interface display terminal is updated.
In the operation of the system, if the state of the terminal changes, all the pagers know that, as shown in fig. 3, after the pager 1 adjusts the volume of the terminal and the like, the state of the terminal changes, new state information is multicast at this time, all the pagers receive the state information, the state information comprises the name of the terminal, the program source and the volume, wherein the name of the terminal can visually identify a specific terminal, the program source of the terminal can identify whether the terminal is in an idle state or a paging/talkback state, and the volume of the terminal can display the volume of paging/talkback sound. The pager will save the new terminal state information and then update the interface.
Paging is directly initiated by the pager and then transmits the data stream to the terminal. As shown in fig. 4, a pager initiates a paging request to a terminal, and after receiving the paging request, a selected terminal enters a paging state, and then the pager multicasts a transmission data stream, and the terminal receives and plays the paging data stream, and directly after the paging is finished, the terminal recovers to an idle state.
The pager and the terminal can talk to each other, and the talk-back process also directly sends data streams to each other. As shown in fig. 5, the pager 1/the terminal 1 can directly initiate an intercom request through the IP address, and after the pager 2/the terminal 2 receives the intercom request, the pager and the terminal can directly send/receive audio or video data stream information, and the intercom can be terminated only by directly hanging up the phone without being influenced by other pagers/terminals.
In summary, compared with the prior art, the invention has the following advantages:
1) the whole system does not need to be configured with a server, and the system cost is greatly reduced.
2) The terminal configuration parameters are very simple and can be used only by configuring the terminal IP.
3) The talkback and the paging directly send data streams to each other, are not influenced by other data streams and have higher stability.
4) The terminal has strong expansibility, can be used by directly accessing a network, and is not influenced by system configuration and the number of terminals.
