Wireless remote control switch principle composition and advantages
With the development of technology, wireless remote control switches are widely used. The wireless remote control switch is designed and manufactured by high-tech radio frequency identification technology. It uses wireless remote control switch device to control all kinds of lighting, home appliances, doors, curtains and other household items. It is a new type of intelligent switch that can wirelessly charge indoor lamps and home appliances. Control, easy to operate, stable and reliable performance, loved by consumers. The following small series introduces the wireless remote control switch for everyone.
First, the wireless remote control switch - composed
The commonly used wireless remote control switch consists of two parts: transmitting and receiving. The principle of the wireless remote control switch is also analyzed according to transmission and acceptance.
The transmitting part is the remote control and the transmitting module. The remote control is used independently as a whole machine, and the wiring pile head is externally led out. The remote control module is used as a component, and the receiving part is superheterodyne and super regenerative receiving mode. The regenerative demodulation circuit is actually a regenerative detection circuit that operates in an intermittent oscillation state.
Second, wireless remote control switch - principle
The wireless remote control switch is composed of a combination of a transmitter and a receiver. The transmitter encodes the controller's control button and modulates it onto the RF signal to transmit a wireless signal. It can also be said to be an encoder. The receiver decodes the received wireless signal and obtains a signal corresponding to the control button, and then controls the corresponding circuit, which is also called a decoder. With the advancement of technology, wireless remote control switches have been widely used in industrial control and wireless smart home fields.
Third, wireless remote control switch - advantages
The installation of the wireless remote control switch is very simple and convenient. It does not need to be connected to the zero line, and does not need to make any changes to the lighting appliance. It can directly replace the original switch. After the power grid is powered off, the switch will automatically be turned off to avoid wasting unnecessary power. It can centrally control all the intelligent remote control switches of the whole family. There are also a variety of styles to choose from, which can be used in a wide range of options. The wireless remote control switch can be combined with traditional mechanical switches for convenience and simplicity.
