浅析红外遥控器硬件设计

由于红外线在光谱里,不属于可见光,所以红外线具有抗干扰非常强烈且安全的特性。根据光波的线性传播特性,相互之间不容易干涉,是优秀的信息传输介质。信息可以通过红外传输直接调制,信息可以通过红外强度传输直接调制,也可以使用红外线生成特定频率的载波。关于信息的发送,后者的方法比较好,但是这是现在看到的大多数红外线遥控器所使用的方法。随着人们生活水平的提高,产品的追求变得更加便利和智能,红外线遥控技术是重要的开发方向之一。

Because infrared ray in the spectrum,does not belong to visible light,so infrared ray has very strong anti-interference and safe characteristics.According to the linear propagation characteristics of light waves,it is not easy to interfere with each other,and is an excellent information transmission medium.Information can be modulated directly by infrared transmission,information can be modulated directly by infrared intensity transmission,or infrared can be used to generate a specific frequency of carrier.The latter is better for sending information,but this is what most infrared remote controls see today.With the improvement of people's living standards,the pursuit of products has become more convenient and intelligent,infrared remote control technology is an important direction of development.
