Special light pen for intelligent platform

Abstract

The invention discloses a special light pen for an intelligent platform, which comprises a pen body. A control part is arranged on the pen body; the control part comprises a heat preservation module;the heat preservation module comprises a temperature sensor, a heating piece, a heat preservation button and a temperature controller; the temperature sensor is connected with the temperature controller; the heating piece is controlled by the temperature controller; the heat preservation button is connected with the temperature controller; the heat preservation button is arranged on the surface ofthe pen body; the pen body is internally provided with a communication module, and the communication module communicates with a terminal; and the pen body is internally provided with a charging module, the charging module comprises a charging module and a charging joint, and the charging module and the charging joint are mutually connected. The special light pen for the intelligent platform has aheat preservation function, a charging function, a microphone function and the like, the surface temperature of the light pen can be maintained due to the heat preservation function, and the heat preservation purpose is achieved, and comfortable use experience is given to a teacher; the light pen with the charging function does not need a battery, and energy is saved; and the microphone is arranged on the light pen, the microphone does not need to be worn, and the teacher can perform teaching at any position in a classroom.

Description

technical field [0001] The invention relates to a light pen, in particular to a special light pen for an intelligent podium. Background technique [0002] The appearance of the light pen is like a ballpoint pen, which is composed of a pen body, a lens group, an optical fiber, a switch and a wire. A light pen is an input device for an electronic computer and is used in conjunction with a monitor. It is sensitive to light and looks like a pen. It is connected to the host with a multi-purpose cable, and can be used for drawing, point control and other operations on the screen. Relying on the light pen program in the computer to input the characters on the display screen or the photosensitive sensor of the cursor position information to the computer. A light pen is an input device for a computer. It has simple structure, low price, fast response, and easy operation. It is often used in interactive computer graphics systems. In the graphics system, the light pen organically co...

Problems solved by technology

[0005] 1. Teachers need to take it with them often, which is very inconvenient and easy to miss

[0006] 2. The light pen is generally made of metal materials. In the cold winter, the surface temperature of the light pen is low, which will easily make teachers feel uncomfortable.

[0007] 3. The existing light pen has a relatively simple function, which cannot meet the increasingly mature multimedia intelligent teaching
