Test box for electronic communication teaching

Abstract

The invention discloses a test box for electronic communication teaching. A password lock is mounted between a box body and a box cover; four containing bags are arranged at the inner side of the box cover; the inner part of the box body is separated into a first placement groove and a second placement groove through a separation plate; a power strip is arranged in the first placement groove; one end of the power strip is connected with an electric wire plug; the electric wire plug is exposed into an external environment of the box body through a through hole; a host is further arranged in the first placement groove; a video acquisition card is mounted in the host; a display screen is arranged at the top of the host; one side of the host is connected with a monitoring camera through a video signal wire; an ammeter is arranged in the second placement groove; positive and negative electrodes of the ammeter are connected with a conductor through lead wires. By adopting the test box disclosed by the invention, an electromagnet can be used for carrying out electromagnetic induction experiments; when the electromagnetic induction experiments are carried out, the monitoring camera is used for monitoring the reading displayed by the ammeter and transmitting a monitored picture to the video acquisition card; the monitored picture is displayed through the display screen of the host.

Description

AI Technical Summary

Problems solved by technology

For courses such as communication principles that need to link theory and practice, corresponding experimental teaching aids are needed as the carrier of theoretical knowledge. However, the current situation is that there is a lack of specialized experimental platforms for communication-related courses.
