Wireless remote control has become one of the indispensable devices in modern families, which greatly improves the convenience of our use of TV and other appliances. The development of wireless remote control has gone through several important stages.
Initially in 1950, the American Zenith Electric company developed the first wired remote control, but it was not until 1955 that the company invented a wireless remote control device called “Flashmatic”
. However, the device needed to be pointed at the TV to be controlled and couldn’t tell if the beam was coming from the remote control, so it didn’t catch on. In 1956, Rob Adler developed the Zenith Space Command remote control, which used ultrasound, and although it had only a few simple buttons, it was an important advance in wireless remote control
.
In 1961, RCA Victor produced the world’s first truly wireless remote control, which has the functions of switching channels, adjusting volume and brightness, and can be said to be the ancestor of modern remote control
. By 1980, with the development of semiconductor devices for transmitting and receiving infrared rays, infrared remote controls began to become popular and gradually replaced ultrasonic remote controls
.
In 2007, SONY introduced the first RF remote control in its BRAVIA series of TVS, which does not need to be aligned with the TV and provides greater freedom of operation
. Today, the wireless remote control has developed to support advanced technologies such as smart homes and the Internet of Things, and with the progress of technology, the shape of the remote control, the type of button and the type of control object are constantly changing.
The classification of wireless Remote Control mainly includes infrared Remote Control (IR Remote Control) and radio remote control (RF Remote Control). Infrared remote control uses near infrared to transmit control signals, while radio remote control uses radio waves for control. The carrier frequency of the radio remote control is usually 315mHz or 433mHz, using the open frequency band stipulated by the state
.
With the rise of smart homes, the demand for wireless remote controls is expanding. Intelligent remote control according to the transmission mode is mainly divided into infrared remote control, radio remote control, ultrasonic remote control, 2.4G wireless remote control, Bluetooth wireless remote control and so on
. The technical content and added value of the intelligent remote control continue to improve, the professional division of labor is becoming more and more obvious, and the whole machine manufacturers gradually put the share to the professional intelligent remote control manufacturers
.
In the future, with the development of technology, wireless remote control may have more intelligent functions, such as voice control, gesture control, etc., but considering the needs of different user groups, the traditional wireless remote control will not die out in the short term
. As the scale of the smart remote control industry continues to expand, it is expected that the wireless remote control industry will continue to maintain a growth trend in the next few years
