A small card, big wisdom 丨 embedded technology open a window for wisdom campus construction
Heard that some schools have recently began school, campus and epidemic prevention propaganda work in this very period how to smoothly? Prevention and control the outbreak, with action, epidemic prevention power class card for wisdom campus, keep the campus this piece of pure land, teachers and students to ensure safety of life!
What is the brand wisdom class?
Class brand is the education informatization and Internet + wisdom arises at the historic moment of the product, the combination of wisdom class card combined with face recognition, big data, AI etc. New technology, promote the development of informatization campus

From meet demand to scene innovation drive
On the starting point is different, solution not only can meet demand ", more to be able to create a new scene and applications,
Wisdom class card can be used as the most practical information release window, displaying the latest school epidemic prevention strategies, the door of the classroom, the corridor, dining room, etc. Without exception, all kinds of epidemic prevention tips by dynamic display, a variety of forms to strengthen teachers' and students' protection consciousness,
Terminal system architecture
Wisdom card system based on campus network, USES B/S architecture, the wisdom of the different parts of the campus through the network class brand terminal connected, through the background control center centralized management, the system can be installed in the independent campus information center machine room, can support the cloud resource application deployment mode at the same time,

Specific design is as follows:
1, the construction control center, in the control center to build the central control server, management workstation,
2, in the classroom, library, such as multi-function classroom wall installation at the gate of wisdom class card terminal,
3, in the campus gateway install outdoor LED screen, can be used for linkage,
Class 4, brand management server is installed in the school computer room cabinets,
5, in every classroom door hanging a wisdom class, class card according to the requirements of the installation position space and environment to choose the appropriate size (size) of the product, with the hanging vertical and horizontal two products to choose from,
Class 6, also can be placed in the teachers' office wisdom card, used to display the school notice and the office all the teacher's curriculum schedule,
Class 7, brand managers can work through the computer remote management all the content of the class shown on the card,

Class card system architecture diagram of wisdom:


Terminal system value
Wisdom class brand benefits brought to school three aspects: efficient notification message, timely feedback information, the transparency of management, implementation class
Efficient notification message
Configuration in each class class a wisdom card, as show the communication window class culture, wisdom class card real-time update the current course information, class activities and school notice information, students can also brand visualized by wisdom class school recent important events, the first time to grasp the campus and the class dynamic,
Feedback the classroom information
Teacher after the class, the students can through wisdom class card touch screen, whether to understand the class information feedback, management background parses the feedback data, analysis which is need to strengthen the teaching, to adjust the pace of teaching, the purpose of improving teaching quality,
Transparent management class
Wisdom class card in hd display, interactive data sharing application is given priority to, students and teachers can swipe attendance, attendance data real-time transmission to the management of the background, and school attendance card, sign function perfect combination, the system also can realize with the school, combined with other systems including docking with the campus IC card system, with a variety of environmental monitoring sensor, according to the data of the docking and the butt joint of teaching system and teaching management system, and the real-time dynamic display and docking information,

Terminal solution
Function of the product positioning is clear, close to the school needs, with face recognition, speech analysis, AI technology such as large data as the means, has solved the campus management, just need wisdom campus construction, small make up recommend two platform solutions,
Solution a: FETA40i -c core board
The cost is low, industrial-grade WenKuan
FETA40i - C CPU core board with lower power consumption of the whole A40i domestic chip, 4 nuclear ARM architecture (A7, faster 1.2 GHz, support Android & amp; Linux dual system, is a high performance, low power consumption, high ratio of industry application processor, satisfies the requirement of the localization, memory, storage and other main control chip are domestic, campus information safer, according to the project demand floor design development function, can quickly achieve the stable and reliable brand terminal,

Scheme 2: FET3399 -c core board
Framework supports a variety of AI/meet different application scenarios
FET3399 -c core board based on core micro RK3399 processor design, Android7.1 systems support Tensorflow Lite, Caffe etc. Various AI framework; And provide platform for RK3399 deep learning target detection routines (RKSSD), the optimized plan for the development use of OpenCL, RGA and other hardware acceleration module, in order to reduce the CPU load,

Have two ARM architecture A72 kernel, faster 1.8 GHz;
Double hardware ISP, the highest support single or double 8 mpix 13 mpix/s/s, support dual camera data input at the same time, for the image recognition application acceleration, support 3 d depth information extraction such as order processing,
10 bits H265 VP9 support 4 k and 4 k/H264 video decoding, as high as 60 frames per second, a more clear picture, to end users of different visual experience,
A variety of display interface, support double screen show, double screen with show, meet a variety of scenarios of intellectual education,






Distance countries released in June 7, 2018, the national standard "wisdom campus overall framework" has been in the past two years time, the wisdom campus, before the outbreak, has always been not good good box office, the epidemic in the education industry and all of a sudden the wisdom campus to the front, let more people realize that vision, to experience the charm of wisdom campus and convenient,

Wisdom electronic class card can merge with infrared measuring temperature, when the person through the infrared temperature measurement, voice alarm, can be returned to the command center through the network at the same time, realize the rapid and accurate temperature screening scale crowd,
Until the commencement of my study, all students and teachers in don't take a mask, only need to line up and through, can be in face recognition is used to detect the temperature at the same time, face, body temperature is normal, sign in to success; When temperature is higher than 37.3 degrees will call the police, not allowed to enter, to ensure that each of the teachers and students are not to enter the campus, in spite of


After the outbreak of wisdom campus development, will usher in the Internet education and intellectual education of the new period, refactoring wisdom of education form, either from the perspective of the development of the related hardware or software will usher in new opportunities,
