Dimming system and method based on pedestrian volume and position information

Abstract

The invention discloses a dimming system and method based on pedestrian volume and position information, and the method comprises the steps: obtaining the advancing information of a mobile terminal, enabling the advancing information to be matched with the coordinates of an earth surface grid in a coverage region, and determining the position of the grid corresponding to the mobile terminal; dividing the mobile terminals in the coverage area into different clusters, obtaining boundary grids of the clusters, and performing area expansion according to the boundary grids to form a control area; when the distance between the extended boundaries of any two control areas is smaller than a merging critical value, merging control is carried out, and the two control areas are classified into the same control area; obtaining the effective resident number of people in each control area, and when the effective resident number of people is greater than a threshold, performing scene switching on thelighting system corresponding to the control area. According to the invention, the position data of the mobile terminal in the coverage area is detected through the wireless probe, real-time dimmingand scene control are carried out according to the position distribution of people, and corresponding light scene switching is triggered through the effective resident number of people.

Description

technical field [0001] The invention relates to the technical field of lighting scene control, in particular to a dimming system and method based on people flow and position information. Background technique [0002] At present, in outdoor scenes such as parks, no matter whether there are people or not, all lighting fixtures work at full power at night, or through microwave and infrared induction, the lights of independent lamps are turned on when people come, and the lights are dark when people leave. There are some problems with independent light control. First, there is a limit to the sensing distance. Second, due to the uncorrelatedness of the sensing end, it is impossible to adjust the surrounding associated lights in real time according to the sensing position. Third, the lighting time after adjustment is a fixed value, which is not smart enough. change. Another way of dimming is remote system control, which realizes intelligent control of lighting through mobile netw...
