Method and device for determining arrangement of illuminance transducer and illumination control system

Abstract

The invention discloses a method and device for determining arrangement of illuminance transducers and an illumination control system. The method comprises the steps that candidate arrangement positions of the illuminance transducers are determined, wherein the candidate arrangement positions of the illuminance transducers comprise positions of all interested points; the influence coefficients of all controllable light sources to the illuminance of all the candidate arrangement positions are determined, and the influence coefficients represent the sensitivity degrees of the illuminance of the candidate arrangement positions on the dimming levels of the controllable light sources; based on a performance evaluation function for evaluating the combined performance of the candidate arrangement positions, the arrangement positions used for arranging a second number of illuminance transducers are selected from the candidate arrangement positions, and the performance evaluation function for evaluating the combined performance of the candidate arrangement positions meets the condition that the lower the correlation among the measurement values of the combination of the candidate arrangement positions is, the higher the performance of the combination of the candidate arrangement positions is. By means of the method and device for determining arrangement of the illuminance transducers, the arrangement of the illuminance transducers is optimized by using correlation, cost can be saved, and the illuminance of all the interested points can still be obtained.

Description

technical field [0001] The present invention relates generally to lighting control, and more particularly to methods, apparatus and lighting control systems for determining placement of illuminance sensors. Background technique [0002] A typical lighting control system includes multiple controllable lighting devices or light sources, multiple illuminance sensors, a central controller, and a communication network. In this lighting control system, when the lighting equipment emits light at a certain dimming level, the illuminance sensor measures the illuminance value on the point of interest in the lighting area, and transmits the measured illuminance value to the central controller via the communication network, and the central control The controller adjusts the brightness of the lighting device based on the difference between the sensed illuminance value and the target illuminance value, so that the illuminance at all points of interest approaches or reaches the desired val...

Problems solved by technology

However, the inventors of the present invention have found that in the lighting control system, this presupposition is not always true, because the measurement results of the illuminance sensor are affected by multiple artificial light sources that are turned on at the same time, and the values ​​of the two sensors at a single moment The similarity of the measurement results is not enough to show that the corresponding two sensors are correlated, so it is not appropriate to remove either sensor by this technique in this case
