地铁车厢灯光自适应控制研究

解决地铁节电问题一直是国内外大力研究的课题。而行驶在高架以及地面段的地铁列车具有天然的采光资源——自然光。根据这一现状，提出一种自适应调节车厢内灯具照度的方法，来达到节约地铁车厢内照明用电的目的。针对自然光随机性高，变化频率快，以及地铁运行时外界环境干扰大的问题，提出采用数字滤波器结合模糊控制的方法，将经巴特沃斯低通滤波器滤除高频干扰的车厢内照度信号传输给模糊控制器，通过模糊控制器的逻辑推理判断处理，实现了地铁车厢灯光自适应地调节车厢内灯具的照度，节约了地铁车厢照明用电。

Research on Adaptive Lights Control in Subway Car

Solve metro power saving problem has been the subject of vigorous research no matter at home and abroad. The subway driving on the elevated and ground segment has natural lighting resources natural light. According to the status quo, this paper puts forward a kind of adaptive adjusting compartment lamp illumination method. To achieve the purpose of saving electricity for lighting in the subway car. According to the problem of that the high random and frequency of natural light, as well as external environment interference when subway running. In this paper, using digital filter combine with fuzzy control. The butterworth low-pass filter to eliminate the high frequency interference, transmission to the fuzzy controller. Through the fuzzy controller logic judging and processing. Realization of the subway car light adaptive adjustment. Save the lighting electricity of subway car.
