Description

A kind of classroom based on Application on Voiceprint Recognition takes attendance in class system

Technical field

A kind of intelligent biological identification equipment is the utility model is related to, more particularly to a kind of classroom based on Application on Voiceprint Recognition is attended class Roll calling system.

Background technology

It is the conventional means for supervising student normally to attend class to take attendance in class, but often occurs class hour playing truant now in university Report for work for answering, get by under false pretences as, the student to play truant generally allows other classmates.

Application on Voiceprint Recognition is a kind of biological identification technology, and the vocal print frequency spectrum that everyone is sent is different, is had stronger Individuality, Application on Voiceprint Recognition have the advantages that to identify that accuracy is high, the fast and indispensable electronic component of recognition speed is cheap.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of classroom based on Application on Voiceprint Recognition and taken attendance in class system, energy The identity for the student that attends class enough is identified by way of Application on Voiceprint Recognition, avoids replacing to answer mutually reporting for work, supervises student to attend class, avoid escaping Class phenomenon.

To achieve these goals, technical solution adopted in the utility model is：A kind of classroom based on Application on Voiceprint Recognition Take attendance in class system, including roll-call controller and vocal print collector；Roll-call controller includes body, the display being arranged on body Screen and control button, the vocal print processing module being arranged in body, voiceprint identification module, voice print database, automatic speech are called the roll Module, class's selecting module, roll-call result memory and short message prompting module, the control button is including power switch and certainly The roll-call key of dynamic voice roll-call module connection and the class's selection key being connected with class selecting module, automatic speech point famous model Block is also associated with loudspeaker.

As a kind of optimal technical scheme of the present utility model, the vocal print collector is arranged on classroom including at least one Microphone and four microphones being arranged on the wall of classroom on ceiling, microphone is wireless by multi-input multi-output system The roll-call controller is connected, multi-input multi-output system includes setting the transmitting antenna of connection microphone and is connected to roll-call control The reception antenna of device processed, each microphone connect a transmitting antenna, and roll-call controller connects five reception antennas.

As a kind of optimal technical scheme of the present utility model, the vocal print processing unit includes sub-frame processing module, filter Ripple device and A/D modular converters.

It is using beneficial effect caused by above-mentioned technical proposal：The utility model can be by way of Application on Voiceprint Recognition To identify the identity for the student that attends class, avoid replacing to answer mutually reporting for work, supervise student to attend class, avoid phenomenon of playing truant, it gathers sound Mode meets the environment in classroom, and be capable of each position student of precise acquisition answers sound, improves identification precision.

Brief description of the drawings

The utility model is described in further detail with reference to the accompanying drawings and detailed description.

Fig. 1 is structural representation of the present utility model.

In figure：1st, roll-call controller 2, vocal print collector 3, body 4, display screen 5, power switch 6, roll-call key 7, Class's selection key 8, vocal print processing module 9, voiceprint identification module 10, voice print database 11, automatic speech roll-call module 12nd, class's selecting module 13, roll-call result memory 14, short message prompting module 15, loudspeaker 16, microphone 17, transmitting Antenna 18, reception antenna.

Embodiment

Referring to accompanying drawing, the structure of one embodiment of the utility model includes roll-call controller 1 and vocal print collection Device 2；Roll-call controller 1 includes body 3, display screen 4 and the control button being arranged on body 3, the vocal print being arranged in body 3 Processing module 8, voiceprint identification module 9, voice print database 10, automatic speech roll-call module 11, class's selecting module 12, knot of calling the roll Fruit memory 13 and short message prompting module 14, the control button include power switch 5, are connected with automatic speech roll-call module 11 Roll-call key 6 and class's selection key 7 for being connected with class selecting module 12, automatic speech roll-call module 11 be also associated with raising Sound device 15.

The vocal print collector 2 includes at least one microphone 16 being arranged on the ceiling of classroom and four are arranged on religion Microphone 16 on the wall of room, microphone 16 pass through roll-call controller 1, multi input described in multi-input multi-output system wireless connection Multiple output system includes the transmitting antenna 17 for setting connection microphone 16 and the reception antenna 18 for being connected to roll-call controller 1, often Individual microphone 16 connects a transmitting antenna 17, and roll-call controller 1 connects five reception antennas 18.

The vocal print processing unit 8 includes sub-frame processing module, wave filter and A/D modular converters.

Operation principle of the present utility model is：Class is pressed first by the voiceprint typing voice print database 10 of all members Stored, and member's cell-phone number is stored in short message prompting module 14；Upper class hour, power-on switch 5, teacher or roll-call are negative Responsibility starts class's selecting module 12 by class's selection key 7, and class's selection is carried out by display screen 4, chooses corresponding class Automatic speech roll-call module 11 is started by roll-call button 6 after level, automatic speech roll-call module 11 will pass through according to member list Loudspeaker 15 is called the roll successively, hears that the student of oneself name answers, and the vocal print for answering student is gathered by microphone 16 and by more Input multiple output system reaches roll-call controller 1, and voiceprint is after the framing of vocal print processing module 8, filtering and is converted into telecommunications Number, vocal print electric signal is contrasted by the data of voiceprint identification module 9 and the voice print database 10 of the class, is sentenced if meeting It is set to the student to come to class, does not meet, be judged to playing truant, in roll-call result deposit roll-call result memory 13, is judged to playing truant Student's list uniformly sent short messages prompting by short message prompting module 14.Short message, which is reminded, can play further supervision role.

Foregoing description only proposes as the enforceable technical scheme of the utility model, not as to its technical scheme in itself Single restrictive condition.
