(2) start pick-up lens unit and rotate angle lens and make radium-shine focus be in CCD sensitive volume all the time, the lasting detecting distance whether out-of-limit duration reaches preset time threshold and captures, capture data and be stored into image ephemeral data district, when image ephemeral data district exists the image information of this candid photograph, undertaken storing and reporting to the police by alarm module; When image ephemeral data district does not exist the image information of this candid photograph, be connected on the mobile terminal of mandate by network, if connect mobile terminal, carry out video speech call, if access failure, buffered video voicemail message.
The invention has the beneficial effects as follows:
1) Smart Power Module balances each modular power source balance of voltage and current stabilization by power management chip, and for whole gate control system provides power supply, wherein modules power supply is mutually isolated, makes system more stable.
2) when biological characteristic validation passes through, the biological information in automatic renewal encrypted memory encrypted private key district, usefulness is: minor is in growth and development process, trickle change can be there is in fingerprint and vein profile, the biological information of automatic renewal validated user, again enrolls registration biological information after at set intervals.
3) during biological characteristic validation failure, by the ephemeral data district of the former data of this physical characteristics collecting information stored in encryption reservoir, biological characteristic and ephemeral data district data contrast, if find, ephemeral data district stored this illegal biological information, then this illegal biological information is sent to warning device, is undertaken storing and reporting to the police by warning device; Especially, the legal biological information of this gate control system mandate can extract illegal biological characteristic raw data, in order to submitting corresponding evidence during alert process to.
4) dead bolt vibration unit is connected with dead bolt, is driven by driving gate locking wire ring signal simultaneously, prevents dead bolt from rubbing excessive, and solenoid burns because of short circuit.
5) display device is after authorizing, and can open opal and check gate inhibition's real-time information by real time remote, also can receive opal timing and capture image information.
