Real-time.
Finger is pressed the fingerprint module at the top of Fingerprint Identification Unit by user may be implemented the initial acquisition of fingerprint, adopt
Collect obtained fingerprint graph and be input to image pre-processing module, image pre-processing module eliminates information unrelated in image, restores
Useful real information in fingerprint image, enhancing fingerprint detectability for information about and to the maximum extent simplified data.In advance
Treated, and image is passed to characteristic extracting module, and characteristic extracting module checks each pixel to determine whether the pixel represents one
Feature crosses local derivative operation to calculate the one or more features of fingerprint image, and enters information into matching module.Matching
Module is by carrying out pair the fingerprint data in the fingerprint base of the fingerprint picture feature of collected user and apparatus of the present invention
Than matching, login module is entered after successful match, user's selection enters English learning system, net class system on-line testing system
System, net class system or online homework system, so far then complete the function logic of fingerprint input subsystem.
After user enters the English learning system suitable for international economy and trade profession:
User wears headset, passes through the typing that voice input subsystem carries out voice: first by speech transducer to using
The reading English sound of person is acquired, and is received by voice receiving module voice messaging, voice receiving module and language

Sound input processor, voice input processor carry out processing noise reduction to the voice of user, filter off useless noise noise.Voice
Input processor and speech memory are electrically connected, and the voice of user is stored into speech memory by voice input processor
In.
Invention device is output by voice the output that subsystem carries out voice: being obtained first by signal receiving unit wait broadcast
The voice messaging put, signal receiving unit and voice output processor are electrically connected, and speech processor turns voice messaging
Amplifier is alternatively sent signal to afterwards, and amplifier, which amplifies voice signal, to be handled and amplified signal is sent to filter
Wave device, filters filter remove impurity sound wave, the voice of standard are carried out sounding by sounding device.User passes through headset
Hear the voice of standard.
Apparatus of the present invention score to the pronunciation of user by pronunciation scoring subsystem: being connect first by inputting voice
The voice messaging that unit receives user is received, and voice signal is sent to points-scoring system, points-scoring system is patrolled by internal
It collects and judges that the pronunciation to user carries out judgement marking, final output appraisal result.
Apparatus of the present invention correct subsystem by pronunciation of words and are corrected to the pronunciation of user: passing through input language first
Sound receiving unit receives the voice messaging of user, and voice signal is sent to identification matching module, by with dictionary it
Between comparison matching, the obtained information of identification sends display output unit by identification matching module, and display output unit will be believed
Breath is sent to display.At the same time, the information that identification obtains is sent voice-output unit by identification matching module, and voice is defeated
Voice messaging is sent to sounding device and carries out sounding by unit out.
After user enters the net class learning system suitable for international economy and trade profession:
User enters net class academic environment by login system first, and user can be according to the course shown on display
Speaker's list selects the lecturer's object of giving lessons admired, and then shows school timetable of attending class that the instructor is ranked in advance by system
So that user is according to the movement of reservation or the cancellation of it's time for class school timetable progress course, user is ranked in advance in instructor
It attends class after the movement for completing curricula-variable in school timetable, was then opened before the class period by tutoring system between attending class live broadcast teaching on a line
Enter for instructor and learner, to carry out online teaching activity.
It should be noted that this system can start before class to check whether the tuition fee of user is sufficient, if user
Tuition fee is sufficient, and user can enter link of attending class and carry out on-line study；If the tuition fee of user is inadequate, then user
It can enter and pay tuition fee interface, user can enter link of attending class and carry out on-line study after paying tuition fee, otherwise
Stopping is opened in gauze class educational function to it.
After user enters the online exam system suitable for international economy and trade profession:
The operating process for the online exam system that apparatus of the present invention are realized is as follows: teacher logs in teacher's system, Jiao Shitong first
It crosses system and uploads examination paper.In authorized examination time range, student login student system carries out online examination after verifying identity
Answer is rolled up, after completion paper is filled in, student clicks the upload for submitting examination to carry out paper, and the paper for uploading completion enters intelligent examine
Module is criticized, the specification answer of intelligent approval module meeting establishing criteria carries out automatic marking and data statistics to the paper that student uploads
And analysis.
At the same time, in the test period, camera module send signal control camera open, camera recorded video to prevent
Only student practises fraud in online assessment, records the video deposit video recording memory of completion.
When user enter suitable for international economy and trade profession after line homework system:
The operating process for the online homework that apparatus of the present invention are realized is as follows: teacher logs in teacher's system, Jiao Shitong first
It crosses system and uploads homework.
At the appointed time range, student login student system carry out online homework answer after verifying identity, complete
After homework is filled in, student clicks the upload submitted and carry out homework, and the homework for uploading completion, which enters intelligence, to be examined
Module is criticized, the specification answer of intelligent approval module meeting establishing criteria carries out automatic marking and data to the homework that student uploads
Statistics and analysis.
System of the present invention can be also used for the Special Technique Training task that teacher arranges student, whole process and examination
Etc. almost the same, no longer illustrate one by one herein.
Described camera, headset, Fingerprint Identification Unit, switch control block, integrated control case etc. are the group of existing equipment
Dress, therefore, concrete model and specification are not repeated.
The working principle of the invention:
After user enters English learning system: the typing of voice input subsystem progress voice: being sensed first by voice
Device is acquired the reading English sound of user, is received by voice receiving module voice messaging, language identification
Module identifies the voice input of user, and voice signal is transferred to voice input processor, voice input processor
Processing noise reduction is carried out to the voice of user, filters off useless noise noise, voice input processor stores up the voice of user
It is stored in speech memory.
Voice output subsystem work principle: voice messaging to be played, signal are obtained by signal receiving unit first
Receiving unit and voice output processor are electrically connected, and speech processor is sent signal to after being converted to voice messaging
Amplifier, amplifier, which amplifies voice signal, to be handled and amplified signal is sent to filter, and filters filter is gone
Except impurity sound wave, the voice of standard is subjected to sounding by sounding device.
Pronunciation scoring subsystem work principle: the voice for receiving user by inputting voice receiving unit first is believed
Breath, and voice signal is sent to points-scoring system, points-scoring system sentences the pronunciation of user by internal logic judgment
Disconnected marking, exports appraisal result.
