Description
Technical field
The present invention relates to a kind of terraced control system using fingerprint recognition, belong to third generation technical field of biometric identification.
Background technology
Elevator is applied more and more extensive in daily life, with the aged development of population, inside some lift cars
Except there is common floor call operation panel, the special disability call operation panel of physical disabilities is also equipped with.Common floor call
Operation panel and disability call operation panel are had any different in some function settings, such as the disability call operation panel when there is button call
Open the door that the retention time in place, the retention time was long in place than the enabling of common call operation panel.In addition, some carry two doors
The car at (such as front door and back door), may there are 4 or more operation panels inside lift car.
In the prior art, it is most of using card managing, it is more advanced to be verified using biotechnology
Management, and fingerprint recognition biotechnology has just developed in this field.When carrying out authentication with fingerprint, acquisition is fingerprint
Characteristics of image, refer to feature existing for ability during live body.And the Psychological inadaptability for being taken as and examining object is avoided, while also will not be because
The influence degree of the external factor such as None- identified after dirt contamination, temperature can be ignored, and be suitable for almost all users.With
Family acceptance is good.In addition to without occurring directly to contact with scanner surface, the scanning process of this Noninvasive was both simple
Again naturally, alleviating user due to worrying sanitation degree or using trouble and resisting psychology that may be present.The fingerprint of user
Feature is difficult to be forged.So fingerprint recognition system safe class is high, the place high particularly suitable for safety requirements uses.But
It there is problems in the prior art to be solved：(1) belong to interior physiological characteristic, will not wear, it is more difficult to forge, there is very Gao An
Quan Xing.(2) non-contact measurement can be achieved, wholesomeness is good, is easy to receive for user.(3) it is not easy by watch face scar or greasy dirt
Influence.Above technology has the drawback that：Collecting device has particular/special requirement, and design is relative complex, and manufacturing cost is high.
The content of the invention
The purpose of the present invention.
The present invention in elevator controlling exactly in order to realize convenient and safe using effect, and the one kind proposed uses fingerprint

Processor is connected, and SD card is connected by SD card interface circuit with more than cortexA8 arm processors, at more than cortexA8 ARM
Intercommunication visual information is transferred to LCD display by reason device by LCD display circuit, is led to audio prompt by audio output circuit
Loudspeaker outflow is crossed, more than cortexA8 arm processors are controlled to the logic communication between fingerprint recognition and circuit,
More than cortexA8 arm processors configure fingerprint module, and visitor carries out fingerprint image extraction and digitized processing, and wherein fingerprint is known
Do not follow the steps below：
Preferably, described power module:12V dc source is provided for access controller circuit system；Ethernet connects
Mouthful:It is responsible for the information transfer of remote network control, while downstream interface is provided for intelligent domestic gateway；Voice module:According to finger
Line recognition result and access control information, voice reminder information is sent to disengaging personnel；Push-button interface:Opening the door, it is true to ask and open the door
The push-botton operation recognized, low and high level signal is sent by I/O interfaces.
Preferably, the voicefrequency circuit mainly includes input and the output processing circuit of audio.Due to audio output signal
It is the analog signal that voltage is more than ten millivolts, thus power amplifier need to be first passed through and carry out gain-adjusted, and A/D change-over circuits is turned
Digital audio and video signals after changing are sent to control chip.
Preferably, the voltage of cortex A8 above arm processor obtains 5V by power supply adaptor transformation, and 5V is electric
Pressure is obtained by low difference voltage regulator AS1117AR-3.3V partial pressures, and its voltage is carried out into voltage stabilizing processing by electric capacity, from
And ensure to provide stable 3.3V voltages for each component and interface and provide 1.8V and 2.5V voltages for camera module.
1st, beneficial effects of the present invention：
Fingerprint bio identification technology is used by the present invention, can accurately identify user identity, and reaction speed is within 2s,
The more place of number is suitable for, improves the degree of accuracy and the efficiency of fingerprint recognition.
Brief description of the drawings：
Fig. 1 is the structural representation of terminal of the present invention；
Fig. 2 is PC card sender structural representations；
Fig. 3 is apparatus for controlling elevator.
Embodiment：
Terraced control system passes through fingerprint ladder control system, typing fingerprint.When fingerprint collecting unit 3 is abnormal, CPU will switch to fingerprint to record
Enter system, combined by both terraced control system alternate runs and with image ladder control system, after by fingerprint, simultaneously
CPU recalls image in resource data pond in contrast, and image similarity reaches ability typing ladder control information after preset value, and ladder control is more
Memberization, validation, accuracy.
