Description
Technical field
The utility model belongs to intelligent terminal field, particularly relates to a kind of sweep circuit structure of intelligent mobile terminal.
Background technology
Intelligent terminal is the GSM network that utilization is moved and UNICOM spreads all over the country, and carries out data transmission by short message mode.Utilize short message to realize remote alarms, remote control, remote measurement three zones, especially GSM message breath, flexibly and easily, can trans-city, transprovincially, even transnational transmission, as long as and often send short message 1 mao, very reliable cheap.For status monitoring, for fire, the warning such as antitheft, equipment failure reports.
Along with the intelligent terminal that apple is released, fingerprint recognition system progressively becomes the standard configuration of intelligent terminal, for fingerprint recognition, current fingerprint recognition also cannot reach corresponding requirement, so prior art needs a kind of new recognition device to carry out comprehensive identification.
Utility model content
The purpose of this utility model is the sweep circuit structure providing a kind of intelligent mobile terminal, is intended to solve the problem that prior art cannot meet accuracy of identification.
The utility model is achieved in that provide a kind of sweep circuit of intelligent mobile terminal, described intelligent mobile terminal comprises: central processor CPU, camera and infrared LED lamp on the one hand; Wherein, infrared LED lamp is the both sides that two rows are arranged on camera, and this sweep circuit comprises:
The output terminal of camera is connected with one end of electric capacity C1, and the other end of C1 is connected with amplifier positive input, and the output terminal of amplifier is connected with CPU1 pin; The reverse input end of amplifier is connected with one end of electric capacity C2, and the other end of C2 connects power supply VC; One end of C2 is also connected with one end of R1, the other end ground connection of R1, and one end of R2 is connected with the reverse input end of amplifier, and the other end of R2 is connected with the output terminal of amplifier; One end of R3 is connected with the positive input of amplifier, the other end ground connection of R3;
The base stage of triode Q1 with Q2 is connected with another pin of CPU respectively; The collector of Q1 with Q2 is connected with power supply VC respectively, the emitter of Q1 is connected with the anode of light emitting diode D1, the negative electrode of D1 connects the anode of D2, the negative electrode of D2 connects the anode of D3, the plus earth of D3, the emitter of Q2 is connected with the anode of light emitting diode D4, and the negative electrode of D4 connects the anode of D5, the negative electrode of D5 connects the anode of D6, the plus earth of D6.
Optionally, the quantity of described infrared LED lamp is 6, and 6 LED are evenly distributed on the both sides of camera.
The utility model compared with prior art, beneficial effect is: because the technical solution of the utility model adds infrared lamp, such camera just can carry out scanning to the finger of user and obtain vein image, then just user can be identified easily by general recognizer, owing to adding the scheme of hand vein recognition, so it has the high advantage of resolution.
