基于无线通信的闪光灯控制系统设计

Design of flashing light control system based on wireless communication

本篇文章立足于无线通讯技术的背景下,详细介绍了如何通过无线控制白炽灯的亮度及其闪烁频率。对于如何通过无线控制白炽灯的亮度,主要是通过红外发射器向单片机发送不同的指令,经解码后,单片机通过定时器中断控制可控硅的触发角,从而控制可控硅的占空比来实现的。对于如何通过无线控制白炽灯使其以不同的频率闪烁,主要是通过灯泡亮与暗的延时时间来实现的。当选定一定的亮度时,通过红外发射的遥控器按键选择不同的延时时间,使白炽灯以不同的间隔时间实现亮-暗-亮-暗的闪烁,进而实现闪光灯的频率控制。

Based on the background of wireless communication technology, this article introduces in detail how to control the brightness and flicker frequency of incandescent lamp by wireless control.For how to control the brightness of the incandescent lamp by wireless, it is mainly to send different instructions to the single chip computer through the infrared emitter. After decoding, the single chip computer interrupts the trigger angle of the SCR through the timer, thus controlling the duty cycle of the SCR. How to control the incandescent lamp to make it flicker at different frequencies is mainly realized by the delay time of light and dark. When a certain luminance is selected, the different time delay is selected by the remote control key of the infrared radiator, so that the incandescent lamp can achieve bright dark bright dark flicker at different intervals, and then the frequency control of the flash lamp is realized.
