Preferably, described client includes the tinkle of bells setting device for pointing out user to have visitor to arrive.
In concrete enforcement, an Intelligent doorbell device, comprising: microprocessor, the detection module of knocking at the door, user interactive module, signal transmission module, data memory module and electric control lock.
Wherein, microprocessor is mainly responsible for the operation of intelligent detection device whole system; The detection module of knocking at the door is used gravity sensing transducer and distance perspective induction sensor, utilizes gravity sensing transducer and distance perspective induction sensor to detect the action of effectively knocking at the door; User interactive module comprises camera, microphone and loud speaker, is mainly responsible for user and obtains visitor's motion video, and carry out speech exchange with visitor; Signal transmission module comprises bluetooth module and WIFI module two parts, is mainly responsible for the transfer of data of this device and client; Live video when data memory module is responsible for preserving unusual condition; Electric control lock is arranged on the entry door of user family, is responsible for controlling user's entry door unlatching.
Client is installed the software systems of intelligent detection device, and runs on backstage, and client is preferably the mobile devices such as mobile phone, panel computer conventionally.
Generally, intelligent detection device is in holding state; Bluetooth or WIFI signal are without connection, and user interactive module Close All, and the shock detection module that only retains door or window is opened.When have visitor to knock at the door or door or window extremely shake, intelligent detection device can record on-the-spot video automatically, and gives corresponding voice message.
After user goes back home, client operating system can automatically detect bluetooth or the WIFI signal of intelligent detection device and connect; The camera of simultaneously opening in the interactive module of family carries out user rs authentication, is verified rear intelligent detection device and can automatically opens door, and permission owner enters or owner's utilization is verified with the client of near-field communication technology modules function.
When there being visitor to arrive also producing and knock at the door after action in front of the door of host, the detection module of knocking at the door in intelligent detection device can detect vibrations direction and the amplitude of door.When being confirmed to be, effectively knock at the door after action, intelligent detection device is transferred to client by bluetooth or WIFI channel by signal.
Client triggers after message to doorbell, and software systems can be play one section of particular ringtone setting in advance, and reminding user has visitor to arrive.
After user confirms to answer, the connection that client meeting and intelligent detection device are set up video and voice; User can check visitor's motion video, carries out speech talkback with visitor simultaneously.
After user confirms that visitor can enter, the instruction that needs input to open the door.Intelligent detection device receives and opens the door after instruction, and entry door is opened automatically.
So far, complete owner and visitor's reciprocal process.
After owner is away from home, intelligent detection device disconnects bluetooth with client or WIFI is connected.
The bluetooth of this device or the connection of WIFI wireless transmission mainly refer to and utilize bluetooth or WIFI technology to carry out transfer of data.
Bluetooth technology be two equipment rooms carry out wireless short-range communication the most simply, method the most easily.Bluetooth 4.0 has been inherited all Inherent advantages of Bluetooth technology wireless connections, has increased the feature of low power consuming bluetooth and High Speed Bluetooth simultaneously, especially take low power consuming technology as core, has greatly expanded the market potential of Bluetooth technology.Therefore after adopting bluetooth 4.0 to connect, can make mobile phone terminal connect arbitrarily within the scope of indoor 50 meters, further reduce device energy-wasting simultaneously.
Wi-Fi is the brand of a Wi-Fi communication technology, by Wi-Fi Alliance (Wi-Fi Alliance), is held.This brand object is the interoperability (part-time property) between the Wi-Fi product improving based on IEEE 802.11 standards.The initial WLAN standard of formulating of the 802.11st, IEEE, is mainly used in solving the wireless access of user and user terminal in office's local area network (LAN) and campus network.802.11a is operated in 5.4G frequency range, flank speed 54,000,000, is mainly used in that remote wireless connections, 802.11b are operated in 2.4G frequency range, flank speed 11,000,000, are progressively eliminated, 802.11g is operated in 2.4G frequency range, flank speed 54,000,000, the up-to-date wireless standard of 802.11n, flank speed can arrive 300,000,000.
User arrives before door, and intelligent detection device can automatically detect bluetooth or the WIFI signal of user mobile phone and connect.According to signal strength signal intensity and the distance between client of bluetooth or WIFI connection, have certain corresponding relation, intelligent detection device can estimate the distance of user and entry door.When user arrives after the distance of setting, intelligent detection device identifies to confirm user's identity again by face recognition or the short distance wireless communication technology, after confirmation user identity is legal, can automatically open door.
Gravity sensing transducer can read falling, tilt, move, place, shake and waving of low acceleration level with high sensitivity on axially tri-of XYZ, and the feature little, low in energy consumption because of its size has been widely used in the Portable movable consumer products such as smart mobile phone, motion detection.The detection module of knocking at the door in intelligent detection device detects with gravity sensing transducer the action of effectively knocking at the door.
Legal when the action of confirming to knock at the door, intelligent detection device can be transferred to client by the wireless channel triggering signal of knocking at the door.Otherwise, illustrate that door has vibrations abnormal, now can automatically open video acquisition intelligent detection device and record a video and store, after going home for user, check.
Client is to knocking at the door after triggering signal, and software systems can be play one section of specific the tinkle of bells, and reminding user has visitor to arrive.
After user confirms to answer, client and intelligent detection device are opened user interactive module simultaneously, and connect.The user interactive module of intelligent detection device is comprised of camera, microphone, loud speaker etc.By camera and microphone, gather visitor's motion video and sound, for user, check.User's voice are played back by loud speaker simultaneously.Completing user and visitor's communication process like this.
After user confirms that visitor can enter, the instruction that needs input to open the door.Intelligent detection device is received and is opened the door after instruction, can control the electric control lock of entry door and automatically open.The electric control lock that intelligent detection device is used can be that motor drives or the control of Electromagnetic Drive is locked.
In order not affect the attractive in appearance of a body, improve the disguise of image collecting device simultaneously, user interactive module corresponding intrument can be placed in opal place, also can share a shell with the detection module corresponding intrument of knocking at the door.Intelligent detection device can be installed by modes such as viscose, sucker, magnet.
In addition the doorbell intelligent opening device of describing in the present invention, also can be arranged on window the security protection for household.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
