基于单片机的红外遥控系统
摘 要
本课题采用低成本的MCS-51系列单片机构成具有高可靠性的遥控系统的应用设计。本设计通过单片机控制实现红外线通信，进而对被控目标实现红外线遥控。基于单片机的红外遥控系统抗干扰性强、功耗低、成本低、易实现，具有很高的实用价值。
本设计是用HS0038红外接收管接收并处理信号，以单片机AT89S52作为信号检测和控制核心。通过单片机可以实现脉冲分配，从而驱动可控硅控制直流电机和由大功率驱动电路74LS14和ULN2003共同组成的步进电机驱动器，结合软件来控制电机的转速、转向。采用LCD1602作为液晶显示界面，可以显示直流电机和步进电机状态、转速，通过与遥控键盘的结合设定电机的速度、方向等值，能使系统在脱离PC机的情况下也可以正常的运行，具有良好的人机交互功能，提高了系统的可用性。采用汇编语言编写模块化程序，增强可读性，便于PC机实现各功能的设置。

MCU-based infrared remote control system
ABSTRACT
The issue is the use of low-cost series of MCS-51 MCU of the remote control with high reliability system applications. The design control through the realization of single-chip infrared communication, and thus charged with infrared remote control goals. MCU-based infrared remote control system and strong anti-interference, low power consumption, low cost, easy to achieve, with high practical value.
The design is HS0038 control infrared receiver to receive and process signals to single-chip AT89S52 as a signal detection and control of the core. Pulse can be achieved through the distribution of single-chip, thus driving thyristor control and by the high-power DC motor drive circuit 74LS14 and ULN2003 stepper motor consisting of (the) driver, combined with software to control the motor speed, steering. Used as LCD1602 LCD interface, can display DC motor and stepper motor, and speed, keyboard and remote control through a combination of setting the motor speed, the direction of the equivalent, will enable the system from the PC in the case of machines can also run the normal , has a good interactive features, improved system availability.The process uses assemble language, with blocking design and more readability and it’s easy to carry out vary settings by PC.
