89C51单片机的学习型遥控器设计+程序
摘要本文设计了一种基于单片机的学习型遥控器，涉及基于单片机的学习型遥控器的原理的详细介绍及实现过程的简单概述。
学习型无线红外遥控器，是用独立的学习方式从而获得对多个模拟机器遥控功能。本设计的基于单片机的红外无线遥控器设计有两种不同的状态：控制状态和学习状态。当处于控制状态的时候，每次用户按一个发送键，则某二进制数据就会由单片机通过指定单元读取，然后串行输出，将某个信号传送出去，到指定的单元中，维持电路。在此同时，系统也正在进行调制信号。这种进程在调制系统中进行，当信号被调制完成后，又会被放大，然后经过二极管，将红外线发射出去。这种被调制后的红外线，可以传输信号给指定设备，从而实现对应的按键对对应的电器设备的控制；另外一种状态是学习状态。当使用人按下一个学习按键时，系统电路就开始采集外界的红外信号，然后将其转化为电信号。通过整形滤波和放大对信号进行采样。最后着存放到特定存储单元，用来以后控制这个设备时使用。68856

Design of Learning Type Remote Controller Based on Single Chip Microcomputer
Abstract
A remote controller is designed in this article. It describes the principle and implementation process of a microcontroller based learning control.
The learning wireless infrared remote control obtain the function of multiple analog remote control by way of using an independent learning methods. This design has two states - learning state and control state. When the user is in control, the user presses a key, and then the MCU reads the binary data through the specified unit. And then it outputs a serial output, which transfers a signal to the specified unit. At the same time, the system is also being modulated signal. this process in the modulation system, when the signal is modulated to complete. The modulated infrared light can transmit the signal to the designated equipment, so as to realize the control of the corresponding electrical equipment; The other state is the learning state. When the user presses a learning button, the system circuit begins to collect the infrared signal, and then convert it into electrical signal. The signal is sampled by means of shaping filter and amplification. At last, it is stored in a specific storage unit, which is used to control the device in the future.
