无线红外显示屏转触控外设的设计

Touch Control Peripheral Device for Wireless Infrared Display Screen

本文设计了一种基于红外线技术的显示屏转触摸屏系统,该系统主要运用红外线收、发管扫描屏幕,当某点的红外线被遮挡时,由红外线传感器采集数据从而计算触摸点位置,并通过蓝牙模块将位置数据发送至终端设备,实现了屏幕和终端设备的无线连接。该系统也可以应用于电视屏幕、宣传屏幕等其他领域,使普通显示屏拥有触摸屏的功能,且解决了外加触屏与终端设备距离远、布线难的问题。

This paper designs a display-to-touch screen system based on infrared technology.The system mainly uses infrared light to send and scan the screen.When the infrared of a certain point is blocked,the infrared sensor collects data to calculate the touch point position.The location data is transmitted to the teminal device through the Bluetooth module,and the wireless connection between the screen and the terminal device is realized.The system can also be applied to other fields such as a television screen,a publicity screen,etc.,so that the ordinary display screen has the function of a touch screen,and solves the problem that the distance between the touch screen and the terminal device is far and the wiring is difficult.
