摘要
设计了一种基于STM32芯片的地铁列车智能LED(发光二极管)照明控制系统。该系统可根据客室环境光强变化实时调节LED灯具亮度。介绍了其工作原理、硬件设计和基于改进一阶惯性滤波算法的程序设计流程图。试验表明,该系统具有成本低、响应速度快、调节精度高、可连续调节等优点,适应未来铁路及地铁照明的发展趋势。
An intelligent LED illumination control system for subway train based on STM32 chip is designed, which regulates the LED illumination in real time according to the changes of light intensity in carriages. In this paper, the operating principle of the system, the hardware design and the programming flowcharts based on the algorithm of one-order inertia filtering are introduced. The experimental results show that the system has advantages of low cost, quick response, high accuracy, and continuous-adjustability. Therefore, this system adapts the trend of illumination in railway and subway systems in the future.
