A method and device for detecting computer surplus in a multimedia classroom

Abstract

The invention discloses a multimedia classroom computer margin detection method. The method comprises the following steps of: controlling, by a teacher end, student ends to be started; recognizing computers by cameras in the student ends through color mark sensors and sending a signal to a PLC controller; carrying out margin statistic by the PLC controller according to a feedback signal; if the margin exceeds a set margin, automatically sending a notification signal by the PLC controller; shutting down the cameras and having a lesson normally; and after the course is ended, shutting down the student ends and resetting the PLC controller. The invention furthermore discloses a multimedia classroom computer margin detection device. The device comprises the teacher end, the plurality of students connected with the teacher end and a control end PLC controller, wherein the student ends respectively comprise a display and a camera; the cameras are provided with color mark sensors and is capable of carrying out color difference recognition and feeding back signals to the PLC controller according to color difference recognition results. The method and device have the advantages and effectsthat computers in a multimedia classroom can be monitored, and if the quantity of faulted computers is high, the PLC controller automatically sends a notification signal to workers.

Description

technical field [0001] The invention relates to the technical field of multimedia teaching, in particular to a method and a device for detecting the surplus of a computer in a multimedia classroom. Background technique [0002] With the rapid development of information technology, the traditional education system stuck in the inherent mode of "chalk and blackboard" has been strongly impacted. At present, computer multimedia is permeating every corner of social life, which will greatly improve people's work efficiency and change people's life. The high-performance campus multimedia system has become an essential hardware facility to measure the school's ability and level. Teachers can guide students through multimedia teaching. At the same time, students are more likely to understand and accept this teaching method with both audio and video. [0003] However, due to long-term use, the computer on the student side often has various problems and cannot be turned on normally. A...

Problems solved by technology

[0003] However, due to long-term use, the computer on the student side often has various problems and cannot be turned on normally. At the same time, the multimedia classroom lacks a convenient way to detect the number of computer failures in the classroom. When there are too many computer failures, the number of computers will not be enough for students to use. The situation seriously affects the teaching of teachers
