Problems solved by technology
[0006] The main purpose of the present invention is to provide a new illuminance sensing system to overcome the problem that the existing illuminance sensing device / illuminance meter cannot sense the illuminance value correctly all the time under the condition that the existing illuminance sensing device / illuminance meter will be partially covered by shadows and method, the technical problem to be solved is to make it possible to correctly sense the illuminance value according to the illuminance value detected by the two illuminance sensing units and a displacement unit, so that one of the illuminance sensing units can automatically avoid shadows

The invention discloses an illuminance sensing system and method. The system comprises a first illuminance sensing unit configured at a first position and used for sensing illuminance of light at the first position to generate a first illuminance value; a second illuminance sensing unit configured at a second position, having a displacement unit and used for sensing illuminance of light at the second position to generate a second illuminance value; and a calculating unit which is electrically connected with the first illuminance sensing unit, displacement unit and second illuminance sensing unit, acquires the first and second illuminance values, acquires illuminance range information by using the first illumiance value, and judges whether the second illuminance value meets the illuminance range information to determine whether to control the displacement unit to move. According to the illuminance values detected by the two illuminance sensing units and the displacement unit, one of the two illuminance sensing units can keep clear of shadow to accurately sense illuminance values.
Description
technical field [0001] The present invention relates to an illuminance sensing system and method, in particular to an illuminance sensing system and method capable of avoiding shadows with a movable illuminance sensor. Background technique [0002] Today's general illuminance measurement is mostly directly measured by illuminance sensing devices and illuminance meters. However, in some specific locations, such as indoors, greenhouses, botanical gardens, forests, pavilions, etc., there are often beams, objects, trees, etc. A variety of shelters, such as sun, will move with the sun due to time and season changes, and the shadows produced by the shelter will also move accordingly. However, the illuminance sensing devices are often installed in fixed positions, so it is difficult to measure Or only partial measurements can be made. Especially in a greenhouse for planting plants, the industry needs to measure the real illuminance value of the planted plants indoors. At present,...
