基于单片机的智能化多媒体电脑遥控装置的设计

摘要

In order to solve the phenomenon which can not be far away from the computer multimedia equipment to operate, this paper proposes a design of intelligence remote control device with multimedia computer based on STC89C51 single-chip microcomputer. In the design, combined with the infrared remote control device, infrared receiving circuit and serial port changed to USB module, it overcomes the inadequate problem effectively. The results show that, the device can automatically identify the remote control signal and decoding, can learn intelligently and custom button functions, Using a remote control aside with this device can break away from the shackles of cable computer, flexible use, convenient operation, cost effectiveness, can be widely used in classrooms, conference rooms, family, entertainment places and other occasions.%为了解决无法远离计算机多媒体设备进行操作的现象。本文提出一种基于STC89C51单片机控制的智能化多媒体电脑遥控装置的设计。在设计中结合红外遥控器、红外接收电路、串口转USB模块，有效地克服了其不足问题。结果表明，该装置能够自动识别遥控信号并解码，可以智能学习自定义按键功能，利用身边任意一款遥控器结合本装置就可以脱离计算机有线的束缚，使用灵活，操作简便，性价比极高，可广泛应用于教室、会议室、家庭、娱乐等场合。
