Door curtain automatic control pushing device based on image collection

Abstract

The invention discloses a door curtain automatic control pushing device based on image collection. The door curtain automatic control pushing device comprises a plurality of hanging mechanisms, and further comprises a sliding rail, sliding blocks and a pushing mechanism; the pushing mechanism comprises an image sensor, an image analyzer, a controller and linear motors corresponding to the sliding blocks in number; the image sensor conducts collection on the human body entering a door frame sensing area and generates image signals; the image signals are analyzed through the image analyzer to obtain the coverage density of the human body in an image; the controller conducts calculation on the coverage density of the human body in the image to obtain a width value of the human body in the image; a needed push-open width value of door curtain bodies on a door frame is calculated to be converted into driving signals for outputting; and the linear motors push the sliding blocks to perform linear motion in the sliding rail according to the driving signals so that the staggered width between door curtain bodies can achieve the needed push-open width value. By means of the door curtain automatic control pushing device, the needed push-open width value of the door curtain is automatically detected and calculated; automation and intelligence are achieved; and pedestrian paths can be conveniently achieved.

Description

technical field [0001] The invention relates to a door curtain automatic control push device based on image acquisition, belonging to the technical field of door curtain control. Background technique [0002] A door curtain is often installed on the door frame. A common door curtain includes a door curtain body, and the door curtain is fixed and suspended on the door frame by a hanging mechanism to isolate hot and cold air and prevent mosquitoes. Such a door curtain has a simple structure, thus It has obvious effects such as heat and cold insulation, cold resistance, low temperature resistance, sound insulation, dust prevention, insect resistance, and odor resistance. It can also facilitate the entry and exit of people, vehicles, and objects. [0003] Although the door curtain can bring the above-mentioned beneficial effects in use, there are still some problems in specific use. For example, in use, the door curtain makes it difficult for indoor light to penetrate, or the o...

AI Technical Summary

Problems solved by technology

Although it can control the gear shaft according to the transmission device to make the door curtain bar rotate, it can only realize the rotation of the angle. If there are many people or when the door frame needs to be opened to a wider area, it cannot be adjusted and cannot be entered in time as needed. The width of the human body in the door frame controls the door curtain, and the staggering of the door curtains cannot be automatically controlled in time according to the sensed human body width to form a passage for the human body to pass through. Therefore, there are still problems in the control structure
