照明用环境光传感器分析数据

通过采集灯具光源腔内部的环境光传感器数据，分析环境光传感器在受到灯具自发光严重干扰情况下还能识别外界太阳光的微小变化，实现灯具日落亮灯、日出灭灯的自动功能。通过对亮灯状态下灯具经过日落到日出的整个工作周期过程的环境光传感器进行实时数据采集，可以得到CH0通道400-700nm可见光谱段的数据及CH1通道400-1100nm接近全光谱段的数据。CH1-CH0的值定义为差值、CH0/CH1的值定义为比值，1min采一组数据、数据＜5组、取当前组数的平均值、数据≥5组、计算最近5组数据的平均值定义为平均差值和平均比值；取日落后采集第120组数据计算得到的平均值定义为基准差值和基准比值；采集第120组数据后、每一分钟判断一次平均差值与基准差异的变化趋势、平均比值和基准比值的变化趋势，当变化趋势一致时判断为自发光的干扰波、当平均差值＞（基准差值+100）且平均比值＜（基准比值-0.01）两个条件同时满足的时候、则可判断为日出，执行灭灯动作。

This dataset is built by collecting ambient light sensor data from inside the light source cavity of luminaires, to analyze the ability of the sensor to detect tiny changes of external sunlight even under severe self-luminous interference from the luminaire itself, so as to realize the automatic functions of turning on the luminaire at sunset and turning it off at sunrise. Real-time data collection is conducted on the ambient light sensor throughout the entire operating cycle of the illuminated luminaire from sunset to sunrise, obtaining data of the CH0 channel covering the 400–700 nm visible spectral range and data of the CH1 channel covering the 400–1100 nm near-full spectral range. The value of CH1-CH0 is defined as the difference value, and the value of CH0/CH1 is defined as the ratio value. One set of data is collected per minute: when the number of collected data sets is less than 5, take the average of the current number of data sets; when the number is ≥5, calculate the average of the most recent 5 data sets, which are defined as the average difference and average ratio. The average values calculated from the 120th set of data collected after sunset are defined as the baseline difference and baseline ratio. After collecting the 120th data set, judge the change trends of the average difference relative to the baseline difference and the average ratio relative to the baseline ratio every minute. If the two trends are consistent, it is determined as the self-luminous interference wave. When both conditions are met: the average difference > (baseline difference + 100) and the average ratio < (baseline ratio - 0.01), it is determined as sunrise, and the light-off action is executed.
