基于光通传递函数矩阵的照度比例模型

考虑照明调光控制系统中在工作面上设置的照度传感器容易受到办公文件、人体等的遮挡而使控制系统误动作,以光通传递函数为基础,建立光通传递函数矩阵,分别提出基于光通传递函数矩阵的单光源和多光源照度比例模型,并采用最小二乘法对比例模型的参数进行估计.现场测试表明,采用该模型计算照度与实测相比较一致性较好,基于该模型的照度传感器设置方法,不但可以减小线路敷设的麻烦,还可以有效解决在工作面上设置传感器时,由于办公文件等的遮挡而导致的系统误动作.

An illuminance ratio model based on a luminance transfer function matrix

An illuminance ratio model of both single and multiple sources was proposed.The model tried to compensate for a lighting dimming system acting incorrectly as a result of an illuminance sensor aimed at a workplace sheltered by paper or a human body.The method was based on a luminance transfer function matrix,and the model parameters were estimated via the least squares method.Simulated and experimental results show the illuminance calculated using the model is consistent with the actual situation.The illumin...
