Problems solved by technology

For example, multiple videos can be imported at the same time, allowing students to freely choose which one to play, and finally count which one has the longest playing time, so as to determine which video is most popular with students. Based on the existing technology, these switches are made by pressing buttons Or touch operation, for the button mode, the experience is poor, but the touch operation is heavily dependent on the touch screen, the cost will increase

Abstract

The invention relates to a rolling switching device and intelligent play equipment comprising the rolling switching device. The rolling switching device comprises a roller, a controller, a light transmitter and a light receiver which is used for receiving the light transmitted by the light transmitter. The light transmitter and the light receiver are connected with the controller. The roller is arranged between the light transmitter and the light receiver and provided with multiple blocks used for blocking the light. The blocks intermittently block light receiving of the light receiver in the rolling process of the roller. The controller transmits a switching signal to the outside when the light intensity received by the light receiver changes. Compared with the devices in the prior art, video switching is realized by the mode of rolling switching so that operation is easy, the cost can be reduced in comparison with touch completion of the touch screen and only one rolling switching device is additionally arranged for implementation.

Description

technical field [0001] The invention relates to intelligent applications in colleges and universities, in particular to a scroll switching device and an intelligent playback device including the scroll switching device. Background technique [0002] At present, playback devices are often equipped in college dormitories for playing promotional videos and advertisements, etc. For this, these playback devices can be used more widely. For example, multiple videos can be imported at the same time, allowing students to freely choose which one to play, and finally count which one has the longest playing time, so as to determine which video is most popular with students. Based on the existing technology, these switches are made by pressing buttons Or touch operation, for the button mode, the experience is poor, but the touch operation is heavily dependent on the touch screen, and the cost will increase. Contents of the invention [0003] The object of the present invention is to ...
