Classroom sound box testing device

Abstract

The invention discloses a classroom sound box testing device which comprises a voice acquisition module, a voice comparison module, a single-chip microcomputer, a signal transmission module and a background server which are sequentially connected. Classroom sound boxes send out a plurality of testing audios; the voice acquisition module is used for acquiring the testing audios sent out by the classroom sound boxes and transmitting the acquired testing audios to the voice comparison module; a preset audio for being compared with the testing audios is arranged in the voice comparison module; when all comparison results are correct after the acquired testing audios are compared with the preset audio, the voice comparison module outputs a high level to the single-chip microcomputer, or else the voice comparison module only outputs a low level; and the single-chip microcomputer converts a level signal to a serial port signal and transmits the serial port signal into the background server through the signal transmission module. The classroom sound box testing device solves the problems that in the prior art, generally, before an examination, a manager needs to carry out one-by-one testing on the classroom sound boxes and mostly, manual detection is carried out, so that phenomena of detection omission and false detection are easy to generate; and working efficiency is very low.

Description

technical field [0001] The invention relates to the field of teaching multimedia devices, in particular to a classroom audio testing device. Background technique [0002] With the development of multimedia devices, school teaching tools are gradually becoming multimedia. At present, school classrooms all have audio systems, which are convenient for teaching activities and various examinations. Before examinations, it is necessary to test the audio to prevent failures. Students take exams, and generally before the exam, the administrators have to test the classroom speakers one by one, most of which are manual inspections, which are prone to missed and wrong inspections, and the work efficiency is very low. [0003] Therefore, it is an urgent problem to be solved by the present invention to provide a classroom sound testing device that can automatically collect the sounds in all classrooms and send them to the background server for detection, which has high detection efficien...

Problems solved by technology

[0004] In view of the above-mentioned technical problems, the purpose of the present invention is to overcome the problems in the prior art that administrators generally have to test the classroom speakers one by one before the exam, most of which are still manually tested, which is prone to missed and wrong detections, and the work efficiency is very low In order to provide a classroom audio test device that can automatically collect the audio in all classrooms and send it to the background server for detection, the detection efficiency is high, and the phenomenon of missed detection and false detection is avoided.
