In the embodiment of the present invention, the preset illumination difference is 20, and in other embodiments, an implementer may adjust the value according to an actual situation.
Step S200, distributing a first weight to the data of the human body proximity sensor according to the installation position of the human body proximity sensor, and carrying out weighted summation on the first weight and the data of the human body proximity sensor to obtain a target triggering frequency; and the target triggering times in unit time are shutter evaluation indexes, and an adjustable shutter set is established according to the shutter evaluation indexes corresponding to the shutters.
When illuminance is too high in the office, office environment of office staff can be influenced, so that intelligent control is further performed on the louver in the office. Before intelligent regulation, a controllable shutter, namely an adjustable shutter, is obtained. Specifically, the method comprises the following steps:
for each louver in an office, a human body proximity sensor is arranged at the top and the bottom of the side edge of the louver and used for detecting whether a person passes through or stops for a long time nearby the louver, the types of the human body proximity sensors are various, and an implementer can select the human body proximity sensors by himself.

The sensor data of the human proximity sensor at the top of the individual blinds,
represents the first
Sensor data of a human proximity sensor at the bottom of the individual blind. When the human body proximity sensor is triggered, setting the sensor data in a triggered state as 1, when the human body proximity sensor detects a human body and the human body is in an unmoved state, continuously keeping the triggered state by the sensor, namely keeping the state quantity of the corresponding sensor as 1 for a period of time, and when the human body is not detected, setting the sensor data in an untriggered state as 0; the detection time period of the human body proximity sensor is set as follows:
. And acquiring the detection state quantity of each shutter sensor in the detection time period, and extracting the state information of the office shutters.
Acquiring each louver of office in detection time period

for detecting the time interval of the blinds
The initial triggering times of the human body proximity sensor at the bottom, the numerical value of the human body proximity sensor which is triggered by the human body proximity trigger every time is added with 1.
Due to the differences in sensitivity and accuracy of the top and bottom body proximity sensors. Therefore, a first weight is assigned to the human body proximity sensor data according to the installation position of the human body proximity sensor, and the first weight of the human body proximity sensor at the bottom is smaller than that of the human body proximity sensor at the top because the detection range of the human body proximity sensor at the bottom is smaller than that of the human body proximity sensor at the top. The first weight of the human proximity sensor at the bottom is 0.35 and the first weight of the human proximity sensor at the top is 0.65 in the embodiment of the present invention.
The first weight and the human body proximity sensor data are subjected to weighted summation to obtain target triggering times, the target triggering times in unit time are shutter evaluation indexes, and the method specifically comprises the following steps: and acquiring a detection time period of the human body proximity sensor, wherein the ratio of the target triggering times to the detection time period is an evaluation index of the shutter.
And constructing an adjustable blind window set by the blind window corresponding to the blind window evaluation index larger than the preset blind window evaluation index threshold, wherein the preset blind window evaluation index threshold can be set by an implementer according to the actual situation.
The bigger this shutter evaluation index is, the bigger the shutter adjustable punishment is, also this shutter of regulation and control can be great to indoor office staff's influence, can realize the detection to the shutter state of office through the acquisition of shutter evaluation index, the adjustable degree of discernment shutter, when the position deployment in the office changes, can obtain adjustable shutter set based on the personnel real-time status in the office equally, need not consider the concrete overall arrangement of office again.
Step S300, based on the adjustable blind window set, establishing an indoor illumination relation model according to the adjusting height of the blind window, the inclination angle of the window sash and the indoor illumination sensor data by using a Gaussian mixture function; and based on the indoor illumination relation model, obtaining the optimal adjusting height of the shutter and the inclination angle of the window sash according to the real-time indoor illumination sensor data.
The intelligent adjustment of the louver is based on the cooperative analysis of the inclination angle of the louver window and the falling height of the louver window, so that the cooperative regulation and control of the window can reach the optimal state, the illuminance in an office can be accurately calculated by utilizing Gaoshan and a model, the relevance between the state of the window and the indoor illuminance can be effectively obtained, and the calculation precision of the indoor illuminance is improved.
Establishing an intelligent shutter regulation and control model based on an adjustable shutter set, defining the initial descending height of an adjustable shutter as zero, and setting the regulation height of a shutter sash for regulating indoor illumination to be 20cm each time, namely intelligently regulating the shutterIn the process, the blind window is adjusted to ascend or descend by 20cm each time. In the invention, the inclination angle of the fan blades of the louver window provided with each louver window can be set to be
80°、
65°、
50°、
35°、
20 degrees and 0 degrees, and the upward angle of the louver window sash is positive and the downward angle is negative when the louver window sash is seen from the indoor. 11 indoor illumination data can be obtained under each height, namely the inclination angles of the sashes of the fan can be adjusted to be 11 at the same height.
