Wireless remote control intelligent lighting system circuit diagram

Lighting systems are closely related to people's lives, but most of today's lighting systems use various types of ordinary switches to turn on and off lamps, and the light brightness is adjusted accordingly through ordinary dimmer switches. Every operation of the lighting system must be done by walking to the switch, and one switch generally can only correspond to one lamp, resulting in the need to install many switches. Therefore, it is very necessary to produce a wireless remote control transmitter that integrates dimming and switching. receiver, which will allow people to freely switch and dim the lighting system accordingly anywhere. Based on this idea, this paper designs a new type of wireless remote control intelligent lighting system. The following is the introduction of this system The research and design process of several important components are introduced in detail.

Research and design of wireless remote control signal receiving module

The wireless remote control signal receiving module is composed of super regenerative detection, amplification, and shaping circuits. The carrier high-frequency signal emitted by the remote control is amplified and detected by the capacitance and inductance of the receiving module and the receiving circuit composed of triodes. It is sent to the triode amplifier circuit for voltage amplification, and then sent to the integrated operational amplifier for amplification. Shaping, the modulated signal in the remote control carrier signal is completely restored and then sent to the input pin of the microcontroller for data decoding. The picture shows the wireless remote control signal receiving module.

Research and design of wireless remote control signal decoding and processing system

In the design of wireless remote control signal decoding and processing systems, the traditional method is to use a dedicated wireless remote control signal receiving chip, but this method brings various limitations in the lighting system design. For example, the signal output by the chip cannot adjust the light. , the number of output signal pins is limited, and more peripheral circuits lead to larger size, etc. Therefore, the single-chip microcomputer produced by Taiwan's Elan Company was directly used to replace the wireless decoding chip and its peripheral circuits.

Design and research of lighting control system

In the design process of the lighting control system, a single-chip microcomputer is used to control the bidirectional thyristor to control the switching and dimming of the lamps. When introducing the design of the wireless remote control transmitter earlier, it was mentioned that its keyboard is divided into groups according to the transmitted signal: "key-on-key group" Wireless signal. After the keyboard is pressed, multiple consecutive sets of wireless signals are emitted, and the signal does not end until the keyboard is released.

In the design process of the wireless remote control intelligent lighting system, the error rate caused by the wireless data signal reading process and the quality of the dimming algorithm have a very obvious impact on the entire system. During the entire design process, the method explained earlier is used to achieve The required functions are that the error rate is lower than that of the standard, and the light changes very continuously during dimming. It is believed that after being put into the market, this product will achieve good market benefits with good practical value. The design and research process of wireless remote control transmitting and receiving devices is introduced. In wireless remote control transmitting and receiving devices, the traditional method is to use dedicated wireless remote control transmitting and receiving chips.
