Development history of wireless remote control


Wireless remote control developed from 1898, with the progress of science and technology, it has been in life more and more applications, to bring people a great convenience.


1. Wireless remote control classification
(1) Infrared remote control
Infrared remote control using a near infrared ray having a wavelength of 0.76 to 1.5 m to transmit a control signal;
(2) radio signal remote control
The use of radio signals on the remote control of various mechanisms of wireless remote control.


2. The working principle of modern remote control
The principle of wireless remote control technology is the transmitter to control the signal line code, and then converted into radio waves sent out. The receiver receives, amplifies, and decodes the radio wave carrying the information, obtains the original control electric signal, and carries on the power amplification to drive the related electrical component to realize the wireless remote control.


3. The origin of the wireless remote control
One of the earliest remote controls of the wireless remote control was developed by an inventor named Nikolai Tesla in 1898 (US Patent No. 613809), called Method Today, where the wireless remote control is already in use Has been more and more applications, to bring people a great convenience.


4. The development prospects of wireless remote control
With the progress of science and technology, wireless remote control also extended to many types, in simple terms, there are two common, one is commonly used in home appliances infrared remote control mode, the other is anti-theft alarm equipment, windows and doors remote control, car remote control, etc. Commonly used wireless remote control mode, infrared remote control is the use of wavelengths between 0.76 ~ 1.5μm near the infrared to send control signals, commonly used infrared remote control system is generally divided into two parts.
