Description
Technical field
The present invention relates in general to the safety door field, more specifically, relates to wireless door control system of a kind of 3G and method and indoor set and off-premises station.
Background technology
Door can be divided into " antitheft door " and " interior door ", and it has both the performance of antitheft and safety.Along with people's is to the growing interest of living space quality, and door has also been born more important role and function.From technical standpoint, door has been born a series of important function such as watertightness, impermeability, Wind-Pressure Resistance, Mechanics of Machinery intensity, heat-insulating sound-insulating and antitheft.In conjunction with Chinese society present situation and people's degree deeply concerned, aly both guarded against theft, safety and modern design, easy to use and door that have humanistic care concurrently be people's optimal selection.But now serious homogeneity phenomenon has appearred in the market product of calling, though it has the function of general door, in design and use, lacks convenience, does not promote the property functional and easy to use of safety door through the means of integrated high-tech product.Such as; When the people visited, indoor occupant can only be gone in front of the door, observed situation outdoors through the opal on the door; Whether decision opens the door then; Outdoor personnel just can judge the indoor people that whether has through the variation that indoor sound that spreads out of and opal appear low-light in this process, and so, the convenience of door and functional has all received influence.
Video intercom; Another name is a video doorbell; The video doorbell system kind is a lot, generally includes off-premises station and indoor set, and off-premises station and indoor set carry out the transmission of signal with mutual through private cable; And indoor set is installed in the fixed position in room usually, so the user need move to the sight that the fixed position could be looked the doorway at indoor set sideways usually.For saving the trouble that the user walks about; Increase the comfortableness and the security of product; Occurred combining the video doorbell system (with reference to disclosed No. 200510082742.4 Chinese invention patent application on 01 17th, 2007) of televisor and/or computer in the prior art, audio-video signal has been exported through televisor and/or computer.The part but the video doorbell system of prior art still comes with some shortcomings on system design and function implementation does not well combine user, gate inhibition and visible dialogue system three.
The video doorbell system (with reference to disclosed No. 200510082742.4 Chinese invention patent application on 01 17th, 2007) of televisor and/or computer has appearred in the prior art combining; This technological technical scheme is: a kind of video doorbell system is provided, comprises off-premises station, signal transmission system, family's display device and controller, gateway; Said off-premises station is used for when the visitor presses doorbell, generating information; Said signal transmission system is used for the audio-video signal from off-premises station is transferred to family's display device; Said controller is used to receive gate inhibition's control signal of user's input; Said gateway is used for sending the off-premises station status command according to the household network communication standard and gives family's display device; Transmit gate inhibition's control signal of user's input and give off-premises station; Said family display device comprises televisor, is used for opening the picture-in-picture Presentation Function according to the off-premises station status command, shows aforementioned audio-video signal.
Be described in detail in the face of this implementation down, its embodiment is following:
Can find out that from Fig. 1 the video doorbell system of prior art comprises off-premises station 110, wireless transmission unit 120, family's audio frequency and video distributor 130, gateway 140, televisor 150 and controller 160; Video terminal (televisor and/or computer) separates with controller here, after indoor occupant obtains corresponding audio/video information through video terminal, seeks controller control gate inhibition again.
Can find out that from Fig. 2 off-premises station 110 comprises doorbell unit 111, imaging system 112, scrambler 113 and gate inhibition's operating unit 114.Doorbell unit 111 is used for when the visitor presses doorbell, generating information; Imaging system 112 is used for generating audio-video signal according to the sight on doorway; Scrambler 113 is used for the signal that imaging system 112 produces is encoded; Gate inhibition's operating unit 114 is used for carrying out according to user's control signal the action of gate inhibition's setting/releasing.
According to Fig. 3, televisor 150 comprises signal receiving unit 151, information receiving element 152, picture-in-picture control module 153, picture-in-picture display unit 154, control unit interface 155, control signal transmitting element 156.Here; Televisor and/or computer as video terminal need dispose corresponding functional modules; No matter be or install additional, all can change its physical arrangement or even outward appearance originally, otherwise need buy televisor and/or the computer that complete compliance with system requires again through repacking.It costs an arm and a leg, and be not suitable for each position (like toilet, kitchen etc.) a large amount of outfits at home, and inconvenience moves at any time again, has limited usage space, has reduced service efficiency.
Consulting Fig. 4, is the workflow diagram of the video doorbell system of televisor and/or computer.
Step S411, when the visitor presses off-premises station, then doorbell sounds, and the doorbell unit can send a jingle bell prompting to gateway through unified network family's communication standard, and gateway sends the doorbell status command to televisor then.
Step S412, televisor open picture-in-picture function after receiving instruction, and the signal source of picture-in-picture switches to off-premises station and passes the image and the sound of coming, and carry out automatic picture-in-picture and show.Herein, indoor occupant can only obtain information outdoors through televisor and/or computer, but can't the sound of oneself be transferred to outdoor personnel through televisor and/or computer, does not realize real video intercom; And off-premises station does not possess in the state that call out the not to have response function of automatic shooting and storage picture down, if in users home, have the guest to visit under nobody situation, then the user can't learn and visit to such an extent that whom people is during this period of time.
Can find out from above-mentioned embodiment; Employed televisor of the video doorbell system of televisor and/or computer and/or computer all belong to the higher relatively equipment of energy consumption; Open state need be supplied power and be in for a long time and audio frequency and video could be in time shown; Even use the notebook computer that is equipped with rechargeable battery, its stream time under the situation that power supply breaks off is also very limited.And; As the televisor of video terminal and/or computer can only be under the state that off-premises station is called out passive demonstration audio/video information; Under off-premises station does not have call state; Indoor occupant can't transfer to video terminal with outdoor situation by the ACTIVE CONTROL off-premises station, and promptly it does not possess outdoor anywhere or anytime monitoring function.
In sum, the video doorbell system of televisor and/or computer is not realized the property at any time of video monitoring, and does not realize the intellectuality of door bell and button system, needs us to do further invention research.
