Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below will the utility model be described in further detail by specific embodiment and relevant drawings.
The utility model provides a kind of building visual talk back entrance guard system based on Session Initiation Protocol, it is characterized in that: comprise an application server, an attaching position register, an indoor machine and an outdoor machine; Described application server, attaching position register, indoor machine and outdoor machine all insert in the IMS core network by Session Initiation Protocol; Described outdoor machine comprises a kernel control module, and described kernel control module connects a button, a SIP communication module, a display screen, a microphone, loudspeaker, a camera, swipe the card module, a power module and a door lock.
As depicted in figs. 1 and 2, present embodiment provides a kind of building visual talk back entrance guard system based on Session Initiation Protocol, it is characterized in that: comprise an application server, an attaching position register, an indoor machine and an outdoor machine; Described application server, attaching position register, indoor machine and outdoor machine all insert in the IMS core network by Session Initiation Protocol; Described outdoor machine comprises a kernel control module, and described kernel control module connects a button, a SIP communication module, a display screen, a microphone, loudspeaker, a camera, swipe the card module, a power module and a door lock.Comprise that also a landline telephone inserts described IMS core network by fixed telephone network.Comprise that also a portable terminal inserts described IMS core network by mobile communications network.Described portable terminal is mobile phone or flat board.
Described application server also comprises an application memory.Described indoor machine is SIP video terminal or a smart mobile phone.The built-in control store of described kernel control module, described kernel control module be a built-in audio-video signal collector and an encoding and decoding processor also.Described power module is made of a direct current power supply, an accumulator and a transformer, and described accumulator is connected with described direct supply, and described direct supply is connected as the AC power of input end with the outside by described transformer.Described SIP communication module can also be connected to described IMS core network by Ethernet.
The utility model discloses a kind of building visual talk back entrance guard system based on Session Initiation Protocol.Utilize the optical fiber of operator and telephone network to realize video doorbell solution based on IMS, common phone, cell phone and desktop multimedia information terminal as the indoor intercommunication of the domestic consumer of gate inhibition's platform and controlling equipment, are made that the wiring of building visual intercom system is more simple.Compared with prior art, the utility model is a kind of based on Session Initiation Protocol building visual talk back entrance guard system, increased 3G digital cordless phones function, wireless phone moves intercommunication, video monitoring and unlocking function, has reasonable in design, simple in structure, easy to use, control characteristics such as automatic.
Indoor machine is that a SIP video terminal or smart mobile phone are arranged in the user family, and outdoor machine is arranged on the stair doorway.Built-in control store in the kernel control module can be stored outdoor machine configuration information and user profile, and configuration information comprises outdoor secret sign indicating number and SIP number of the account, and user profile comprises SIP number of the account and the card number of swiping the card.
In order to make persons skilled in the art better understand hardware structure of the present utility model, below in conjunction with Fig. 1 and Fig. 2 and hardware structure of the present utility model principle of work of the present utility model is described.
Divide several situations to describe below:
1. when the visitor calling party; The visitor only need import floor number and the room number of resident family, initiation is to user's call request (outdoor machine directly filters non-religious name by judging figure place), this call request sends to the IMS core network, the IMS core network is inquired about this user video doorbell service of whether having contracted by attaching position register HLR, if have then this call request triggers arrived application server, application server is according to the number of outdoor machine, judge whether legal calling by the called telephone inventory, if the legal number of then inquiring about this open air machine corresponding codes (as " coding+building, residential quarter number coding+cell encoding ") and bundling according to this room of this coded query; Application server inquire corresponding indoor plane No. sign indicating number (and fixed telephone number and mobile terminal number) back by the IMS core network according to the type of binding number by the calling of different network initiations to this number, when resident family's connection phone, the visitor just can carry out the video intercommunication with resident family.After resident family confirms visitor's identity, send one and open the door information to outdoor machine (for example pressing " # " key on the telephone set), outdoor machine is opened the gate inhibition gate after receiving this enabling signal, hangs up the telephone then to refuse the visitor and enter.
2. when user oneself will enter the room; At this moment, there are three kinds of modes selective.First kind of mode opened the gate inhibition gate by button and 6 passwords of display screen input of outdoor machine; The second way, the card that will open the door is placed on the seat of swiping the card, and the module of swiping the card of outdoor machine is opened the gate inhibition gate after the identification automatically; The third mode with the SIP number of the outdoor machine binding of call, is opened the gate inhibition gate behind the system validation user identity.
3. user's remote monitoring; The user can behind the system validation user identity, realize the video monitoring to outdoor machine at any time by the SIP number of the outdoor machine binding of call.
Above-listed preferred embodiment; the purpose of this utility model, technical scheme and advantage are further described; institute is understood that; the above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
