Abstract
The invention discloses a photo-sensor threshold setting method, photo-sensor and shading system. The photo-sensor threshold setting method includes the following steps: acquisition of natural light, performing digital process to the light intensity of the natural light; setting threshold by taking the obtained digital light ray intensity as a reference. Because the invention captures the current natural light as a reference when setting the threshold of the photo-sensor, so that the user can have a very intuitive perception of the light intensity of the natural light corresponding to the threshold when setting the threshold; and because the position of the photo-sensor are identical at the threshold setting stage and the control stage, the light incidence angles of the natural light are almost identical, so the user can accurately set the expected light intensity as a threshold only by setting the threshold based on the natural light intensity when it is expected to set as threshold at an appropriate time, which is very convenient and accurate.
Description
Technical field
The present invention relates to the optical sensor technical field, in particular, relate to a kind of photo-sensor threshold setting method and used the optical sensor and the shading system of this establishing method.
Background technology
Along with the development of Smart Home technology, optical sensor has entered in the daily life.Just can realize that as in shading system, adding optical sensor its structure as shown in Figure 1 according to the robotization control of light intensity to shading system.
The shading system of existing band optical sensor all is usually when threshold value setting step, pre-set threshold value in the optical sensor; After being provided with threshold values, during the stage, natural light acquisition module and photoelectric conversion circuit by optical sensor collect the magnitude of voltage that can embody light intensity information in control, relatively whether this magnitude of voltage reaches default threshold values again, detects light intensity and has satisfied default threshold values condition.After the threshold values condition satisfied, optical sensor then notified the motor of shading system to rotate, and realized the robotization control of shading system.
Can be owing to everyone be different to the light impression, light intensity that may be same, the somebody wishes that shading system launches sunshade, the somebody but wishes the closed not sunshade of shading system; Add the position difference that optical sensor is installed, the angle of incidence of light difference all can cause under same available light condition, light sensors to light intensity but be different.Therefore, the threshold values that is preset in the optical sensor is difficult to unified the setting.
In order to address this problem, also be provided with regulator potentiometer in the optical sensor that has, regulator potentiometer has provided an interval that can be set to threshold values, and in the setting stage, the user feels that rule of thumb the knob by regulator potentiometer is provided with a current potential as threshold values in this is interval.At the optical sensor normal operating phase, optical sensor is by comparing the potential value of regulator potentiometer and the potential value of current light conversion, when the potential value of current light conversion is greater than or less than (according to setting in advance) this threshold values, the action of control shading system.Because the potential value of regulator potentiometer is very abstract, the user can only set the stage now with feeling to try to set threshold values, test this threshold values at normal operating phase again and whether can under the light intensity of wanting, cause the shading system action, again return the setting stage again and adjust threshold values, in the normal operating phase test, this threshold values method to set up often needs through repeatedly regulating the requirement that just can reach the user again.
And in some comparatively accurate optical sensors, especially in using in vitro optical sensor, in order to carry out sensing control according to light intensity accurately, also be provided with more accurate illuminometer in the optical sensor, can measure concrete light intensity data; With the threshold values of accurate light intensity numerical value, carry out precision control as optical sensor.Not only cost is higher owing to this optical sensor, and the kind of light and the incident angle of light etc. are required comparatively harshness, can not be used for natural light, is not suitable for being widely used in the shading system.
