A door curtain automatic control push system based on image acquisition

Abstract

The invention discloses an image capture-based image capture push system for door curtains. The image capture push system comprises at least one hanging mechanism, a sliding rail, sliding blocks, an image capture unit, an image analysis unit, a control unit and linear motors, wherein the image capture unit is arranged on a door frame, and is used for capturing a human body entering the induction area of the door frame and generating an image signal; the image analysis unit is used for analyzing to obtain the coverage density of the human body in an image; the control unit is used for calculating the coverage density of the human body in the image to obtain the width value of the human body in the image, working out a width value to which door curtain bodies on the door frame need to be pushed, and converting the width value into a drive signal for controlling the motion of each motor and outputting the drive signal; the linear motors are respectively and fixedly arranged on the sliding blocks; each linear motor is used for driving the corresponding the sliding block according to the drive signal to do linear motion in the sliding rail so as to push the door curtain bodies on the hanging mechanism, and the stagger width between the door curtain bodies is driven to reach the width value to which the door curtain bodies need to be pushed. The image capture-based image capture push system disclosed by the invention automatically detects and calculates the width value to which the door curtains need to be pushed, and is more automatic and intelligent, and is capable of conveniently providing a pedestrian path.

Description

technical field [0001] The invention relates to an image acquisition-based automatic control and pushing system for a door curtain, which belongs 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 pene...

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
