Multifunctional demonstration pen data transmission method and product

Abstract

The invention discloses a multifunctional demonstration pen data transmission method and a multifunctional demonstration pen data transmission product. The multifunctional demonstration pen data transmission method comprises the following steps that: each kind of synchronous data is transmitted by dedicated channels; asynchronous data are transmitted by one channel in a shared manner; and different asynchronous data are packaged into data packets having different packet headers. The method can be compatible with the prior art and can ensure response time. A multifunctional demonstration pen comprises a pen body, a pointer, an audio signal collecting device, a volume control device, a PPT control device, a wireless receiving module and a wireless transmitting module, wherein the pointer is arranged at the top of the pen body, the audio signal collecting device is arranged at the bottom of the pen body, the volume control device is arranged at one side of the pen body, the PPT control device is arranged on the surface of the pen body, the wireless transmitting module is arranged inside the pen body and transmits audio signals, volume control signals, PPT control signals and / or data signals, and the wireless receiving module is embedded in the pen body. The multifunctional demonstration pen can pick up sound in demonstration; and the multifunctional demonstration pen is advantageous in reasonable and comprehensive functions, and portable convenience.

Description

technical field [0001] The invention belongs to the field of electric operation teaching aids, and more specifically relates to a data transmission method and product of a multifunctional demonstration pen. Background technique [0002] During the teaching process and the report at the venue, the speaker usually uses a demo pen to indicate the content of the remote demo board. The demo pen usually has the function of a laser pointer, which can emit laser light and form a light spot on a distant demo board to indicate the content. The presentation pen helps the speaker to communicate with the audience, making the content of the class or speech more vivid, and at the same time allows the speaker to stay away from the demo version for a certain distance, which is flexible and convenient to operate. [0003] At present, most presentation pens also have a page-turning function. When using an electronic presentation document (Power Point, PPT), they also have a page-turning funct...
