Abstract
The utility model discloses a fingerprint signature box control circuit and a fingerprint signature box. The circuit comprises a master controller, is controlled by functional keys and a capacitive touch induction electrification module, is connected with a fingerprint processing module through an I2C protocol, is connected with a motor through a motor driving module and is connected with a speaker through an OTP (One Time Programmable) voice control module; and an in-place unlocking switch is connected to the master controller to serve as a control component. The circuit has the advantages of superior antistatic performance, high induction sensitivity, strong anti-interference capacity, capability of automatically adapting to dry and wet fingers, reliable and safe work, and large output current and large moment of a motor driving part. According to the fingerprint signature box using the control circuit, important devices are arranged on a lower box, so that the influence of working vibration on components is reduced, and the working life and the reliability can be improved.
Description
Technical field
The utility model relates to a kind of safe deposit box, especially a kind of seal, document storage box that utilizes fingerprint recognition to carry out switch.
Background technology
The fingerprint recognition case is a kind of safe deposit box that is usually used in service trades such as bank, office, is mainly used in important items such as depositing seal, document, in the above-mentioned environment for use, should consider that the effective and safe of article is deposited, and takes into account the convenient access of frequent use again.Traditional key, coded lock all are not suitable for above-mentioned application, and having fingerprint recognition only is the solution of most convenient.
Fingerprint recognition case in the market; Especially common fingerprint seal case mainly adopts semiconductor scratch type sensor, and critical piece as: fingerprint sensor, motor, lockset etc. all are installed in the loam cake of casing; Open and the chest that closes all can produce vibration at every turn; Be enough to the operate as normal of these parts is exerted an influence, reduction of service life, improve fault rate.On the other hand, the control circuit of existing fingerprint seal case is also more common, comes with some shortcomings, and is little etc. like the motor-drive circuit output current.
The utility model content
The purpose of the utility model is to invent a kind of novel fingerprint case---refer in particular to escutcheon mirror case---control circuit of use, and a kind of fingerprint seal case that uses this circuit that be more suitable for.
The described control circuit of the utility model contains master controller, responds to the module controls that powers on by function button and capacitance touch, and passes through I
2The C agreement connects a Fingerprint Processing Module; Connect motor later on through motor drive module, through OTP speech control module control connection loudspeaker; The location switch of unblanking in addition is connected on the master controller as control auxiliary.
Preferably: described master controller is that model is the technical grade single-chip microcomputer of EM78P173N, built-in OTP type ROM.
Fingerprint Processing Module is the totally-enclosed one encapsulation fingerprint module of Doptic company.
Motor drive module is 5 transistored bridge drive circuits, is connected on the master controller through the two-way control line.
A kind of fingerprint seal case that uses above-mentioned control circuit; Constitute by casing, lockset, motor and control circuit; Described casing is made up of upper box and lower box two parts; Lockset, motor and control circuit all are arranged on the lower box, and the function button of control circuit is arranged on the front surface of lower box.
The control circuit of the fingerprint seal case of the utility model has used novel components and parts, and antistatic property is good, and induction sensitivity is high, antijamming capability is strong, and can adapt to dried wet finger, reliable operation safety automatically; And motor-driven part output current is big, moment is big.Use the fingerprint seal case of this control circuit, on important devices setting and lower box, reduced the influence of operational vibration, can improve working life and reliability components and parts.
Description of drawings
Fig. 1, the control circuit structure chart of the utility model.
Fig. 2, the constructional drawing of the seal case of the utility model.
Fig. 3, the mechanical part layout of the utility model.
The specific embodiment
Like Fig. 1, it is the technical grade single-chip microcomputer of EM78P173N that the master controller 1 of the control circuit of the utility model adopts model, built-in OTP type ROM.Function button 2 is responded to the module 3 that powers on capacitance touch it is carried out control connection; Mainly be to realize operation; Capacitance touch is responded to the module 3 that powers on and is adopted the TTP223B chips; Have characteristics such as highly sensitive, that antijamming capability is strong, power consumption is low, just can start master controller 1 and carry out work with the finger touch capacitance touch induction module 3 that powers on.Pass through I on the master controller 1
2The C agreement connects a Fingerprint Processing Module 4; This module is mainly accomplished fingerprint recognition and is handled; In the present embodiment, preferably use the totally-enclosed one encapsulation fingerprint module of Doptic company, this module has the algorithm for recognizing fingerprint that wet finger adaptive technique and advanced person are forbidden and done to remaining fingerprint.Master controller 1 connects motor 9 through motor drive module 6, through OTP speech control module 5 control connection loudspeakers 8; The location switch 7 of unblanking in addition is connected on the master controller 1 as control assembly.
Use a kind of fingerprint seal case of this control circuit; Like Fig. 2; Its casing is made up of upper box 13 and lower box 12, and lockset, motor and control circuit all are arranged on the lower box 12, especially are pointed out that: the function button 2 of control circuit is arranged on the front surface of lower box 12.
What Fig. 3 showed is the internal control frame for movement layout of the fingerprint seal case of the utility model.Lockset 13 is arranged in the peristome of lower box 12, and control circuit is arranged in the middle and lower part with the Fingerprint Processing Module 4 that is attached thereto, motor 14 control locksets, and the position of next door and lockset is equipped with the location switch 7 of unblanking.
