Wireless remote control switch circuit diagram and principle
With the social progress, wireless remote control switch is a lot of use, wireless remote control switch is the use of high-tech radio frequency identification technology designed, with wireless remote control switch equipment control all kinds of lighting, home appliances, doors, curtains and other household items, is a new Intelligent switch, can be indoor lighting, home appliances, such as wireless control, simple and convenient operation, stable and reliable performance, by the vast number of consumers love and sought after, the following is a small series of wireless remote control switch the specific introduction.
In understanding the principle of wireless remote control switch, we first look at the wireless remote control switch function, wireless remote control switch in the design of the use of radio frequency identification technology, no direction, and other products with the same type will not cause any impact and interference, Confidentiality, stable performance, low power consumption, large storage capacity, easy to use, you can let the lights at the same time or individual light, switches and remote control do not have to support the purchase, the user can freely optional, low bit error rate, anti-interference ability. Wireless remote control switch installation is simple and easy, do not need to take the zero line, do not need any changes to the lighting appliances can be directly replace the original switch, power grid after power failure, the switch will automatically shut down, to avoid unnecessary waste of electricity , You can focus on all the family control the intelligent remote control switch. In the style design is also varied, available for a wide range of options, wireless remote control switch can be used in conjunction with the traditional mechanical switch, easy and simple.
Wireless remote control switch - principle
The wireless remote control switch is composed of both the transmitter and the receiver combination, the transmitter will control the control keys through the code, modulated to the RF signal to send out the wireless signal can also be said to be an encoder. And the receiver is to receive the wireless signal to decode the encoded signal to get the signal corresponding to the control button, and then to control the corresponding circuit work, also known as the decoder. With the scientific and technological progress wireless remote control switch in the field of industrial control and wireless intelligent home have been widely used.
Wireless remote control switch - classification
As the scientific and technological progress of wireless remote control switch type and function, according to the transmission control command signal carrier can be divided into: radio remote control, ultrasonic remote control, infrared remote control, according to the signal coding can be divided into: frequency coding and pulse coding, The number of transmission channels can be divided into: multi-channel remote control and single-channel, according to the same time to transfer the number of different instructions can be divided into: single and multi-channel remote control, according to the command signal control of the target control technology can be divided into: Proportional remote control.
Wireless remote control switch - composition
Daily more commonly used wireless remote control switch from the transmitter and receiver of two parts, the principle of its wireless remote control switch is also in accordance with the launch and acceptance to analyze. The remote control module is used as a whole machine, the external lead has a wiring pile head, the remote control module is used as a component, the receiving part is superheterodyne and super regenerative receiving mode, Regenerative demodulation circuit It is actually a regenerative detection circuit that operates in an intermittent oscillation state.
