Hand-held electronic multimedia teaching system

Abstract

The invention discloses a hand-held electronic multimedia teaching system and relates to the technical field of intelligent teaching management. The teaching system comprises an intelligent sign-in system, a multimedia teaching system, a teacher hand-held terminal and student hand-held terminals. Compared with the prior art, the hand-held electronic multimedia teaching system has the advantages that: in the lesson preparation stage, a teacher only needs to upload the courseware to a teacher client of a teaching management center or store the courseware to the hand-held terminal in advance; and in the teaching process, the teacher only needs to connect the hand-held terminal to a projector through a WiFi, and thus play of the teaching courseware can be realized, and meanwhile, the students can also enable the student hand-held terminals to be connected with the teacher hand-held terminal through the wireless WiFi, and interaction between the teacher and the students is realized. The system can realize intelligent sign in; and when the students enter the classroom, an RFID reader-writer arranged beside the door of the classroom can identify campus card information of the students automatically, and the information is then sent to the teacher hand-held terminal through the WiFi network to realize sign in.

Description

technical field [0001] The invention relates to an intelligent teaching management system of a wireless sensor network. The system combines the characteristics of the RFID technology of the Internet of Things and the WiFi communication technology, uses the RFID technology to identify the information of the student's campus card, and transmits the sign-in information to the teacher's hand-held terminal through wireless WiFi , In the teaching process, the information interaction between the teacher's handheld terminal, the student's handheld terminal, and the wireless WiFi projector is realized through wireless WiFi, so as to realize convenient and multi-functional teaching management services. Background technique [0002] At present, the multimedia teaching system is mainly composed of computers, multimedia teaching platforms, LCD projectors, electric silver screens and other multimedia classroom equipment.

Problems solved by technology

[0002] At present, the multimedia teaching system is mainly composed of computers, multimedia teaching platforms, LCD projectors, electric silver screens and other multimedia classroom equipment. The multimedia teaching platform is connected and controlled by pre-embedded lines. It is necessary to carry a USB flash drive with courseware and copy the courseware to the computer, or connect your laptop to the projector through the VGA interface for teaching. This is not only cumbersome to prepare before teaching, but also difficult for teachers to do at any time during the teaching process. Interact with students, and the general pre-class student attendance inspection work is basically paper-based check-in or roll-call answering check-in, which is inefficient and takes too long
