Abstract
For the condition of turning out for work of promptly and accurately mastering classroom teaching middle school student, effective prevention is failed to register and is emitted the condition such as step on to take place, and reliable assurance teaching activities high efficiency is develoied, the utility model provides a portable type educational administration attendance device is including power module, microprocessor module, man -machine interface module, fingerprint identification module, voice module. The device adopts low -power consumption device and low -power consumption design, utilizes the lithium cell to supply power, has broken through the restraint that attendance system of traditional educational administration is bulky, use mains power supply to have this outstanding advantage of mobility, especially adapted use is real -time this specific scene of attendance in the classroom.
Description
Technical field
The utility model relates to identification field, particularly relate to the living things feature recognition field based on fingerprint identification technology, educational administration's work attendance in real time in institution of higher learning's teaching classroom can be widely used in, under the prerequisite not affecting normal teaching order, carry out educational administration's work attendance to high efficient and reliable.
Background technology
At present, such device on the market and published patent, what usually adopt is that multi-purpose computer or the controller not considering power consumption control.Although such system function is complete, capacity is large, have that cost is high, volume and a defect such as power consumption is larger, be thus not suitable for carrying with, application scenario is also subject to certain restrictions.Especially in on-fixed work attendance place and the little occasion of capacity.Such as, under colleges and universities' credit system, check class attendance just can not apply mechanically at present hard-wired this fingerprint attendance machine on the market.This is just meaningful owing to only having the work attendance of student with class-teaching of teacher Complete Synchronization, that is work attendance should be carry out class-teaching of teacher while, this with regard to need attendance record terminal can when class-teaching of teacher in student freely orderly transmission carry out collection student fingerprint.This is obviously the insurmountable technical matters of fingerprint attendance machine being fixedly mounted on work attendance place at present on the market because power problems needs mains-supplied.So developing a set of educational administration's Work attendance device that is efficient, intelligent and mobile work reliably has important practical value.
Summary of the invention
The purpose of this utility model is exactly the deficiency for above-mentioned existing educational administration Work attendance device, proposes a kind of movable-type educational administration Work attendance device.This device adopts low energy-consumption electronic device and low power dissipation design, lithium battery is utilized to power, breach the constraint that traditional educational administration attendance checking system volume is large, use mains-supplied, thus there is this outstanding advantages of removable work attendance, be highly suitable in classroom practical in real-time this special scenes of work attendance.Support student information typing, fingerprint comparison, interpolation fingerprint, delete fingerprint, amendment upgrades fingerprint and display checking-in result.
For achieving the above object, the utility model by the following technical solutions: a kind of movable-type educational administration Work attendance device, comprises supply module, microprocessor module, human-machine interface module, fingerprint identification module, voice module; Described supply module is connected with microprocessor module, human-machine interface module, fingerprint identification module, voice module respectively powers; Described microprocessor module is connected with human-machine interface module, fingerprint identification module, voice module.
Further, supply module described in the utility model adopts lithium battery group to power, for microprocessor module, human-machine interface module, fingerprint identification module and voice module are powered.
Further, processor module described in the utility model adopts low-power scm, is responsible for the various control signals of this device need of work of generation, from fingerprint identification module, reads comparison result and management man-machine interface.
Further, human-machine interface module described in the utility model comprises input submodule and display sub-module, and input submodule adopts determinant non-coding matrix keyboard, and display sub-module adopts low power consumption liquid crystal module.
Further, fingerprint identification module described in the utility model comprises optical fingerprint sensor and DSP, optical fingerprint sensor is for gathering student's finger print information, and DSP is used for take the fingerprint eigenwert, fingerprint comparison and fingerprint search.
Further, voice module described in the utility model adopts digital audio-power amplifier module, for pointing out operating result.
Accompanying drawing explanation
Fig. 1 is the utility model system schema composition frame chart.
