Data transmission method

Abstract

The invention discloses a data transmission method which comprises steps as follows: an infrared remote controller and a receiving end establish two-way communication connection by using two-way instruction frames; the infrared remote controller, which is integrated with a mouse element, generates a mouse data frame suitable for infrared transmission when detecting that a user operates the mouse element, and transmits the mouse data frame to the receiving end; the infrared remote controller, which is integrated with a keyboard element, generates a keyboard data frame suitable for infrared transmission when detecting that a user operates the keyboard element, and transmits the keyboard data frame to the receiving end; and the receiving end receives the mouse data frame and the keyboard data frame transmitted by the infrared remote controller, respectively converts the mouse data frame and keyboard data frame into USB data supporting HID (human interface device) protocol, and provides the USB data for the operating system to call. The invention can implement two-way transmission of the infrared remote controller data, so that the infrared remote controller implements all the functions of the USB mouse and the USB keyboard in an electric appliance which is installed with a common operating system and remotely controlled by the infrared remote controller.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for two-way data transmission of an infrared remote controller. Background technique [0002] Infrared remote control is a short-range wireless control device, which can remotely control various electrical appliances, which brings great convenience to people's lives. For example, with an infrared remote controller used to remotely control a TV, the user can directly use the number keys on the infrared remote controller to change channels, and use the volume adjustment keys on the infrared remote controller to control the volume of the TV set. [0003] In the process of realizing the present invention, the inventor found that the existing infrared remote controllers have at least the following problems: the current infrared remote controller and the receiving end cannot realize the function of two-way data communication; the functions of the standard USB mo...
