One kind is attended class attendance checking systemThe field
It attends class attendance checking system the present invention relates to a kind of attendance checking system, especially one kind, belongs to attendance checking system technology neck of attending classDomain.
Background technique
At present due to the lasting increased enrollment of colleges and universities, so that the quantity of university student is persistently expanded, therefore bring on student-directedDifficulty, constrained due to lacking, the students of many self-control differences becomes lazy decadence after entering university, and the phenomenon that playing truant is more nextIt is more serious, and existing student attendance checking system of attending class is mostly fingerprint recognition, it not can avoid student and check card showing of playing truant again later,And the development of science and technology brings possibility to the appearance of more intelligent attendance checking system.
Summary of the invention
The purpose of the present invention: for the deficiency of existing attendance checking system, the present invention provides one kind and attends class attendance checking system, Neng GouzhiEfficiently the attendance of student can be managed.
To achieve the goals above, the present invention adopts the following technical scheme:
One kind is attended class attendance checking system, including microcontroller, and the microcontroller includes student information recording module, Xue ShengxinIt ceases database and student enters and leaves Information Statistics module；The microcontroller is electrically connected with single into administrative unit, outgoing managementMember, power module, satellite time transfer module and wireless transport module, the microcontroller are connected with backstage by wireless transport moduleTerminal.
Further, it is described into administrative unit include the entrance control module being connected with microcontroller, into control mouldBlock is electrically connected with the first infrared trigger module, the first face recognition module, the first fingerprint supplementary module and the first voice promptingModule.
Further, the described first infrared trigger module is infrared light curtain, and first face recognition module includes high definitionVideo camera and light aid, the first fingerprint supplementary module are fingerprint machine, and first voice cue module is speech player.
Further, the outgoing administrative unit includes the outgoing control module being connected with microcontroller, the outgoing controlMolding block is electrically connected with the second infrared trigger module, the second face recognition module, the second fingerprint supplementary module and the second voiceCue module.
Further, the described second infrared trigger module is infrared light curtain, and second face recognition module includes high definitionVideo camera and light aid, the second fingerprint supplementary module are fingerprint machine, and second voice cue module is speech player.
Further, the power module is rechargeable lithium battery, and the satellite time transfer module is big-dipper satellite time service mouldBlock, the wireless transport module are wireless network card, and the background terminal is the PC that can be networked.
The beneficial effects of the present invention are:
1, include satellite time transfer module in the present invention, can accurately carry out time synchronization, be provided accurately for attendanceTime basis；
It 2, include entering administrative unit and outgoing administrative unit in the present invention, it can be to the accurate discrepancy feelings for understanding studentThe case where condition analyzes the true class period of student, and student midway is avoided to play truant；
3, entering administrative unit and outgoing administrative unit in the present invention includes face recognition module and fingerprint supplementary module,Attendance quickly and stably can be carried out to student.
The present invention can intelligently, efficiently be managed the attendance of student in summary.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, completeSite preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based onEmbodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every otherEmbodiment shall fall within the protection scope of the present invention.
Please refer to Fig. 1-4, the present invention provides one kind and attends class attendance checking system, including microcontroller, and the microcontroller includesStudent information recording module, student information data library and student enter and leave Information Statistics module；The microcontroller is electrically connected withIt is logical into administrative unit, outgoing administrative unit, power module, satellite time transfer module and wireless transport module, the microcontrollerIt crosses wireless transport module and is connected with background terminal.
In the present embodiment, further, it is described into administrative unit include the entrance control module being connected with microcontroller,The first infrared trigger module, the first face recognition module, the first fingerprint supplementary module and are electrically connected with into control moduleOne voice cue module；The first infrared trigger module is infrared light curtain, and first face recognition module includes that high definition is taken the photographCamera and light aid, the first fingerprint supplementary module are fingerprint machine, and first voice cue module is speech player；InstituteStating outgoing administrative unit includes the outgoing control module being connected with microcontroller, and the outgoing control module is electrically connected with secondInfrared trigger module, the second face recognition module, the second fingerprint supplementary module and the second voice cue module；Described second is infraredTrigger module is infrared light curtain, and second face recognition module includes high-definition camera and light aid, and second fingerprint is auxiliaryHelping module is fingerprint machine, and second voice cue module is speech player；The power module is rechargeable lithium battery, instituteStating satellite time transfer module is big-dipper satellite time service module, and the wireless transport module is wireless network card, and the background terminal is canThe PC of networking.
The present invention is when implementing:
It is entered into student information data library firstly the need of by the name of student, student number, fingerprint, figure information, into pipeUnit setting is managed in classroom entrance, administrative unit of going out is arranged in classroom exit, when there is student to enter, triggering the firstOne infrared trigger module controls the first face recognition module and is shot and located after receiving trigger signal into control moduleReason, into control module, by treated, image information is sent to microprocessor, and microprocessor is transferred in student information data libraryFigure information identification is compared after, microprocessor control student enters and leaves Information Statistics module to counting into student,When there is student to go out, the second infrared trigger module of triggering, outgoing control module are received after trigger signal with above-mentioned same firstThe mode of sample counts outgoing student；When recognition of face failure can also by the method for fingerprint recognition assist attendance intoThe normal use of one step guarantee attendance.
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art,It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc.With replacement, all within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in thisWithin the protection scope of invention.
