射频控制在空调产品的应用

Application of Radio Frequency in Air-conditions

目前空调产品都采用红外控制,红外线有很强的方向性,穿透能力差,只适于单向的通讯的弱点;射频控制由于具有距离远、无障碍、低功耗、支持更为复杂的协议等优点,将会逐步取代传统的红外遥控方式。现在的空调产品组网最常见的总线是RS485,很多家庭都没考虑组网的布线,所以无法实现家电的集中控制,只能采用单对单的控制方式。射频可解决了这些需要布线的烦恼,轻松实现组网。射频控制需要解决的重要问题就是目标对象的识别,则FRID,射频的控制为实现家电物联网奠定基础。

At present, air-conditions are controlled by infrared, but infrared has a strong direction performance, poor penetrating power, weakness of one-way communication; however, Radio frequency controller due to its advantage of distance, barrier-free, low power consumption, support for more complex protocols, etc., will gradually replace the traditional way of infrared remote controller. Now, the most common bus of air-condition networking is RS485. Generally, people will not take the network wiring into account. So it is unable to achieve centralized control but can only one-way control of household appliances. RF can address these troubles of wiring, and achieve networking easily. And what the important problem the RF control needs to solve is the target object recognition; therefore, FRID lays the foundation of home appliances networking for the RF control.
