Cloud of the present utility model education intelligence system, compared with prior art, its advantage main saliency is in three below side
Face, we are described in detail for these three aspect now.
1, low-cost and high-performance recorded broadcast, live classroom, intelligent audio system, hardware facility integration, save time, laborsaving, save
Cost.
Acoustic connection, in order to be able to reach to meet teaching demand, is required strict in terms of finishing by traditional fine work classroom, right
The ceiling in classroom, surroundings wall, ground, curtain etc. carry out sound-absorbing, quiet, noise reduction etc. and process.Need to purchase in terms of equipment investment
Put interactive recording player, intelligence instructor in broadcasting's platform, teacher's image lock automatic tracking system, student's image lock automatic tracking system, plate
Book sensor, high-definition camera, digital processing unit, passive sound amplifying sound box, recording microphone etc..Huge fixture and fitting fare, purchasing expensive
Equipment, outlying rural area cannot bear this huge expense, does not meets the state basic policy (everybody is logical, Linking All Classes, Campus Interconnectivity) of China,
Cannot popularize.
In order to really realize that everybody is logical, Linking All Classes, Campus Interconnectivity, need to make low cost, high-tech replaces the religion of existing fine work
Room scheme.Cloud of the present utility model education intelligence system is implemented without again fitting up classroom, by teacher's hand-hold wireless in classroom
Microphone or wear wireless microphone, student utilize multiple Wireless pickup collect sound, wireless sound box, wireless teacher's image lock
The price inexpensive cost energy advantageous apparatus such as automatic tracking system, student's image lock automatic tracking system combine together, it is achieved tradition
The sound-absorbing in classroom, quiet, noise reduction etc. process, it is achieved classroom interactions, interesting teaching;Allow Chinese each village can bear low opening
Pin just can reach to reach even beyond tradition classroom level.
The technology such as 2, brand-new image recognition tracking technique, easily reduces classroom, Intelligent human-face identification work attendance realize interaction religion
, interactive recorded broadcast.
Use that the software algorithm technology such as motion tracking analysis, recognition of face can realize recorded broadcast, live, teachers and students are intelligent examines
The functions such as diligent, long-range monitoring.The traditional "Duck-stuffing" type of teaching lacks interest, dryasdust, it is impossible to improve students ' interest of study and
Efficiency.Modern education, by the interaction of wireless microphone sound academics and students's immediate communication, is vivo recorded by wireless camera
Or the corollary equipments such as remote playing, can be regarded as teachers and students and carry out a kind of life and the contacts of life, communication, teaching process
Regard the unified reciprocal effect of learning aid that an active development and interacting activity process as, in this process, by excellent
The mode of change " interactive teaching and learning ", i.e. by regulation teacher-student relation and interaction thereof, forms the classroom interactions of harmony, life life mutually
The individual interaction with teaching intermediary of dynamic, study, the reciprocal effect of strengthening human and environment, to produce resonance, reach to improve religion
Learn a kind of structure of teaching pattern of effect.Two-way video is mutual and the interactive teaching platform system of courseware recorded broadcast function, contentedly
Trans-regional modern distance teacher's training between all schools of district, Bureau of Education, remotely assessment being discussed, examination hall monitors in real time, Internet video meeting
View, remote teaching guidance, course network direct broadcasting, long-range working present, academic discuss Web conference, before examination interaction such as are answerred questions at the information
Link up, help education administrative department to organize some prominent teachers to record courseware, offer sync instruction course, solve local qualified teachers with
Educational resource energy imbalance, it is achieved local educational Equilibrium development;Carrying out teaching activities by network, unification is prepared lessons, unified religion
Progress, the local Education Informatization Level of overall lifting and teachers in primary and middle schools' education and instruction level under information technology environment,
General Promotion quality of instruction.
3, people-oriented, simple and easy to control.
Cloud of the present utility model education intelligence system function is highly integrated, embedded live, the recorded broadcast of integrated machine equipment, program request,
Touch-control, image trace, video conference, interactive teaching and learning, instruction analysis, local monitor, in one, are possible not only to individually manipulate, moreover it is possible to
Centralized management.System focuses on Consumer's Experience in global design, from manager, user, the angle of implementer, with artificially
This, make every effort to functionally accomplish " practical ", accomplishes " simply " in manipulation.System supports the cross-platform browser of various equipment comprehensively
Access the APP Schema control management of live, program request and achievement unit pyrene cardiac function;Network remote instructor in broadcasting can be passed through, automatic or hands
Move and carry out real-time instructor in broadcasting, definitely embody teachers' instruction by later stage instructor in broadcasting's software and be intended to;Easily realize WEB online editing class
Part, multichannel audio-video frequency synchronizes cutting, it is not necessary to install any software;Can comment in real time while program request courseware, comment content with
Courseware synchronizes, and teacher can carry out adjusting and the lifting of self teaching level of content according to comment.System is adhered to expansible simultaneously
Property, the leeway of secondary development and upgrading is fully taken into account for school user.School can be carried out on the basis of the recording and broadcasting system of campus
Upgrading, does not destroy original structure, makes full use of existing equipment and system, only need to add relevant device, system-based framework and industry
Business application extension Seamless integration-, easily disposes, makes school user have more choice.Can also in the operation maintenance in later stage
Realize the remote upgrade of software and the function of online upgrading.
Described above is only preferred embodiment of the present utility model, and above-mentioned specific embodiment is not to this utility model
Restriction.In technological thought category of the present utility model, various deformation and amendment, the ordinary skill of all this areas can occur
Retouching, amendment or the equivalent that personnel are made as described above, belongs to the scope that this utility model is protected.
