Abstract

The invention discloses a wireless transmission system and a corresponding transmission system method for an optical touch screen. The system comprises the optical touch screen, a transmitting module and a receiving module, wherein the transmitting module comprises a main controller and a wireless transmitter, the main controller is installed on the optical touch screen and used for calculating coordinate data of a touch point on the optical touch screen and sending the coordinate data to the wireless transmitter, and the wireless transmitter is used for sending out the coordinate data of the touch point in a point-to-point wireless communication mode; the receiving module comprises a wireless receiver and a secondary controller, the wireless receiver is used for receiving the coordinate data of the touch point and sending the coordinate data to the secondary controller, and the secondary controller is connected with the wireless receiver and used for controlling the communication between the wireless receiver and an outer computer. The invention further discloses a corresponding wireless transmission method for an optical touch panel. The wireless transmission system and the wireless transmission method can replace the traditional technical scheme of wire transmission and have the advantages of high response speed, simplicity and convenience in operation, convenience in carrying and the like.

Description

technical field [0001] The present invention relates to the technical field of optical touch screen equipment, in particular to a wireless transmission system and a corresponding method for optical touch screens, which are mainly used for communication between optical touch screens and computers, and can transmit single-point or multi-point sent to the host computer. Background technique [0002] As a demonstration device for human-computer interaction, optical touch screens are widely used in all walks of life in society. However, the existing optical touch screen devices have two disadvantages: one, the optical touch screens on the market are all wired devices based on USB cables, which is not conducive to carrying; second, the distance limitation of USB communication makes the distance between the host and the touch screen cannot too far. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems in the prior art, ...
