Abstract

The invention discloses an infrared data transceiver based on a USB keyboard protocol. The transceiver comprises a receiving head circuit D1, an MCU processing circuit U1, a USB interface circuit P1, and a peripheral driving circuit P2, wherein the communication of the MCU processing circuit U1 with other equipment adopts a USBHID protocol without the need of driving, and the supply voltage of the transceiver directly adopts the direct current + 5V of the USB interface; the receiving head circuit receives infrared command data and outputs the infrared command data to an infrared decoding module in the MCU, after the MCU decodes the infrared command data, the data is encoded into specific keyboard value signals, and the keyboard value signals are sent to other equipment by a USB; system equipment can send a command to the MCU through the USB, and after the MCU decodes the command, the MCU sends the decoded command to the peripheral driving circuit. Aiming at the defects of the conventional infrared data receiving equipment, the interactive communication equipment of main control and an infrared receiving module is designed.

Description

technical field [0001] The invention relates to an infrared transceiver device, in particular to an infrared data transceiver device for data interaction. Background technique [0002] With the advancement of science and technology and the development of industries, electronic devices have been widely used in daily life and work. In the field of home appliances such as televisions and medical equipment such as vision testers, the electronic circuits are gradually entering the development of integration, modularization and standardization. [0003] The traditional remote control method mainly uses the system processor to read the infrared receiving code. Since there are many infrared protocols, different receiving heads require different decoding procedures, and the circuit structure is also different. This method also has high requirements for the transmission of the remote control, which must be matched with the receiving circuit to realize data connection. Moreover, thi...
