Bluetooth communication based cloud blackboard system

Abstract

The present invention discloses a Bluetooth communication based cloud blackboard system. The cloud blackboard system comprises: intelligent writing hardware and an intelligent terminal. The intelligent writing hardware comprises a writing touch pad, a Bluetooth communication module connected with the writing touch pad, and a battery module. The writing touch pad is used for writing and recording a content. A writing operation can be performed on the writing touch pad, and written information is transmitted to the Bluetooth communication module. The Bluetooth communication module is used for data exchange of the written information between the writing touch pad and the intelligent terminal. The battery module is used for supplying power to the writing touch pad and the Bluetooth communication module. The intelligent terminal performs data exchange of the written information with the intelligent writing hardware, and the intelligent terminal records voice of a user when the user is writing, integrates voice information and written information to form an audio-video stream, and sends the audio-video stream to a network cloud server to realize cloud data sharing. According to the system provided by the present invention, class teaching efficiency of teachers can be improved, and reviewing class knowledge after class is more convenient for students.

Description

technical field [0001] The invention relates to an intelligent cloud blackboard, in particular to a cloud blackboard with BLE Bluetooth technology. Background technique [0002] Now people have been in a new era, an era from Internet thinking to Internet habits.

Problems solved by technology

However, looking at the domestic education environment, it is still in the face-to-face traditional teaching mode of "blackboard + chalk" where teachers teach students to learn.

In the traditional teaching mode, the teacher's explanation is the main method, the class time is limited, and there are many knowledge points. In the limited class time, the teacher cannot take care of every student. The differences in learning habits and acceptance progress among different students often lead to the differences between classroom knowledge points and knowledge points. Problems cannot be absorbed and solved in a timely manner; students often have nowhere to turn for help when encountering problems during review after class. These phenomena seriously affect the teaching effect and learning efficiency

[0003] For these common problems in education, there is no product on the market that can solve them in a timely and effective manner, making these phenomena a helpless intractable disease that often occurs in
