Wireless remote control intelligent lighting system circuit design
Lighting systems are closely related to people's lives, but most of today's lighting systems use all kinds of ordinary switches to turn on and off the lamps. The brightness adjustment of the lights is also adjusted by ordinary dimming switches. Every time the lighting system is operated, it must go to the switch to complete, and a switch can only correspond to one luminaire, which requires a lot of switches to be installed. Therefore, it is very necessary to produce a wireless remote control transmitter that integrates dimming and switching. Receiver, which will enable people to switch and dim the lighting system freely anywhere. Based on this idea, this paper designs a new wireless remote intelligent lighting system, the following for this system A detailed description of the research and design process of several important components. Research and design of wireless remote control signal receiving module The wireless remote control signal receiving module is composed of a super regenerative detection, amplification and shaping circuit. The carrier high-frequency signal transmitted by the remote controller is amplified by the signal received by the receiving circuit composed of a triode or the like through the capacitance and inductance of the receiving module, sent to the triode amplifying circuit for voltage amplification, and then sent to the integrated operational amplifier for amplification. After shaping, the modulation signal in the carrier signal of the remote controller is completely restored and sent to the input pin of the single chip microcomputer 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 processing system, the traditional method uses a dedicated wireless remote control signal receiving chip, but this method brings various limitations in the design of the lighting system, for example, the signal output by the chip cannot realize the adjustment of the light. The number of output signal pins is limited, and the number of peripheral circuits leads to a large volume. Therefore, the single-chip microcomputer produced by Taiwan 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, the single-chip microcomputer is used to control the bidirectional thyristor to achieve the purpose of controlling the switch and dimming of the luminaire. The design of the wireless remote control transmitter mentioned earlier refers to the keyboard according to the transmitted signal: Wireless signal: When the keyboard is pressed, multiple consecutive wireless signals are transmitted until the keyboard releases the signal. In the design process of the wireless remote intelligent lighting system, the error rate and the dimming algorithm caused by the wireless data signal reading process have obvious influence on the whole system. In the whole design process, the method explained above is realized. The required function has a lower error rate than the light, and the light changes very continuously during dimming. I believe that after entering the market, the product will achieve good market benefits with good practical value. The design and research process of the wireless remote control transmitting and receiving device is introduced. In the wireless remote transmitting and receiving device, the traditional method is to use a dedicated wireless remote transmitting and receiving chip. solar flood light,High Quality solar flood light,solar flood light Details, CN ZHONGSHAN G-LIGHTS LIGHTING CO., LTD. , https://www.glightsled.com
