Intelligent remote control structure and category in smart home

The remote control is a kind of mechanical device used for remote control. It is composed of integrated circuit board and buttons used to generate different information. Through modern digital coding technology, the key information is encoded; the light wave is emitted by the infrared diode, and the infrared wave signal received by the receiver is converted into an electric signal by the infrared receiver of the receiver, and is decoded by the processor to demodulate the corresponding instruction. , to control the set-top box and other equipment to complete the required operational requirements.

Intelligent remote control technology

Many appliances use infrared remote control. Infrared remote control uses near-infrared light with a wavelength of 0.76 to 1.5 μm to transmit control signals. The commonly used infrared remote control system is generally divided into transmitting and receiving two parts. The main component of the emitting part is an infrared light emitting diode. It is actually a special light-emitting diode. Since its internal material is different from ordinary light-emitting diodes, it emits infrared light instead of visible light when a voltage is applied to both ends. The receiving part of the infrared receiver is a photodiode.

Smart remote control is divided into two categories: physical remote control and remote control applications

1 The physical remote controller refers to the real object with a remote controller, which is a traditional remote controller.

Its classification is as follows:

a) Three primary color LED remote controls. Its control method is: using 26-key infrared remote control, with memory storage function.

In general, the superimposed three primary colors are red, green, and blue, and the subtractive primary colors are magenta, yellow, and cyan.

b) Air Conditioning The remote control is used to control the air conditioner for mode setting and temperature adjustment. Snow on the screen represents cooling mode; water droplets represent dehumidification mode; sun represents heating mode; fan represents supply mode;

c) universal air conditioner remote control. Universal air conditioner remote control is specially designed for many types of air conditioners, the remote control is difficult to match and other issues, set the main functions of the remote control in one, suitable for nearly 50 kinds of brands of air conditioning use. This kind of remote control adopts imported chip design, stable performance, with a large LCD screen, Chinese display, simple operation.

2 remote control applications. As the Internet penetrates into various industries

Internet products have also begun to appear in various industries. b Remote applications (APPs) can be found in the Apple Store and Android Market. The application of this type of application is to install the software on the phone, and then open this software to control the content of the TV.
