【摘要】 文中提出基于51系列单片机的红外智能遥控器设计方案。该遥控器采用测量脉冲宽度的原理,具有自学习功能,能记忆与学习遥控器编码,并模拟发射,使得一个遥控器能够代替多个遥控器控制不同的家电。同时针对使用中发现的抗干扰问题进行研究,适用于多数电子产品的遥控。实验结果证明了方案的可行性。更多还原

【Abstract】 This paper presents a kind of design scheme of intelligent infrared remote controller based on 51 series MCU. The remote controller, with self-study function which is implemented by pulse width measuring, has the ability to receive and learn the code of infrared instructions from others and repeat it again. So we can use only one remote controller, instead of several, to control many different electro-appliances .We have made many studies on the interference resistance for the problem met in our experiments. It fits for most electric products in most conditions. The test result has verified the practicability of the design.更多还原
