Background technology
Along with popularizing of computer, computer and daily life contact more and more closer, but most people compares the privacy focusing on computer usually when using computer, usually need to use keyboard to carry out simple password combination to operate, but password combination is easily decrypted by various means, safety coefficient is not high.
Utility model content
It is simple that the purpose of this utility model is just to provide a kind of structure to solve the problem, the keyboard of the face recognition verified by face recognition.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises keyboard body, described keyboard body is provided with camera head, photosensitive sensors, hummer, wireless communication transceiver, dynamic light filling circuit, single-chip microcomputer, pwm control circuit and infrared LED lamp group, the data output end of described camera head is connected with the data input pin of described single-chip microcomputer respectively with the data output end of described photosensitive sensors, the data output end of described single-chip microcomputer is connected with the data input pin of described wireless communication transceiver, the control output end of described single-chip microcomputer is connected with the control input end of described hummer and the control input end of described dynamic light filling circuit respectively, the output terminal of described dynamic light filling circuit is connected with the input end of described pwm control circuit, the output terminal of described pwm control circuit is connected with the input end of described infrared LED lamp group.
Particularly, described wireless communication transceiver is infrared communication transceiver, bluetooth communication transceiver and WIFI communication transceiver.
Further, described camera head by support and described keyboard body hinged.
The beneficial effects of the utility model are:
The utility model realized face recognition checking by the camera head be arranged on keyboard, control hummer sends and reminds operating personnel to leave operating position when failing the authentication, structure is simple, there is dynamic adjustments light filling circuit, when carrying out face recognition, facial light source can be kept stable, obtain optimized image, guarantee authenticity and the security of certification.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is structured flowchart of the present utility model;
In figure: 1-keyboard body, 2-wireless communication transceiver, 3-camera head, 4-infrared LED lamp group, 5-photosensitive sensors, 6-hummer.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As illustrated in fig. 1 and 2, the utility model comprises keyboard body 1, keyboard body 1 is provided with camera head 3, photosensitive sensors 5, hummer 6, wireless communication transceiver 2, single-chip microcomputer, dynamic light filling circuit, pwm control circuit and infrared LED lamp group, the data output end of camera head 3 is connected with the data input pin of single-chip microcomputer respectively with the data output end of photosensitive sensors 5, the data output end of single-chip microcomputer is connected with the data input pin of wireless communication transceiver 2, the control output end of single-chip microcomputer is connected with the control input end of hummer 6 and the control input end of dynamic light filling circuit respectively, the dynamic output terminal of light filling circuit is connected with the input end of pwm control circuit, the output terminal of pwm control circuit is connected with the input end of infrared LED lamp group 4.
In order to ensure when carrying out face recognition, keep facial light stability, obtain optimized image, guarantee authenticity and the security of certification, preset the light intensity what a Parametric Representation CMOS infrared photography module obtains optimized image, the light intensity that imageing sensor in CMOS infrared photography module is gathered environment by dynamic adjustments light filling circuit and the parameter preset compare, calculate light-source brightness offset, control pwm control circuit output pwm signal and carry out the luminous intensity light filling that pulse-length modulation controls infrared LED array.Dynamic adjustments light filling circuit and pwm control circuit are existing mature technology.
Wireless communication transceiver 2 is infrared communication transceiver, bluetooth communication transceiver and WIFI communication transceiver, support the transmission of multiple kinds data, camera head 3 by support and keyboard body 1 hinged, after verifying, can remove and facilitate keyboard operation by camera head 3.
When photosensitive sensors detects that insufficient light needs to carry out light filling operation time, single-chip microcomputer controls dynamic light filling circuit according to light intensity provides the current signal of needs to pwm control circuit, meet the power demands of infrared LED lamp group, the facial signal line collection of operating personnel gathers human body face image information by camera head 3 and delivers to single-chip microcomputer and be transferred to single-chip microcomputer again, personal file in the information and date storehouse of input is compared by wireless communication server 2 by single-chip microcomputer, send the data communication interface that control command returns to wireless communication server 2, control hummer sends and reminds operating personnel to leave operating position when failing the authentication, structure is simple, there is dynamic adjustments light filling circuit, when carrying out face recognition, facial light source can be kept stable, obtain optimized image, guarantee authenticity and the security of certification.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included in protection domain of the present utility model.
