Direct-current brushless motor control mechanism

Abstract

The invention relates to a direct-current brushless motor control mechanism which comprises electric cabinet doors arranged on the two sides of a bookcase and used for achieving door closing and opening operation of the bookcase under the control of a direct-current brushless motor; a direct-current brushless motor used for driving the electric cabinet door to open the door of the bookcase when receiving the door opening control signal; and authorization verification equipment used for receiving the enhanced replacement image, carrying out feature matching on image features of the enhanced replacement image based on preset authorized personnel face features, sending a door opening control signal when a percentage value of feature matching exceeds a preset percentage threshold value, and otherwise, sending a door closing control signal. According to the mechanism, the privacy protection capability of the bookcase can be improved.

Description

technical field [0001] The invention relates to the field of automatic bookcases, in particular to a DC brushless motor control mechanism. Background technique [0002] Bookcases are divided into single-sided bookcases and double-sided bookcases. Bookcases can be connected infinitely according to the frame. School books and bookcases are generally divided into 6 layers. Of course, it can also be 4 layers and 5 layers according to the situation. The conventional specification is that each frame has a width of 900-1000, a single-sided bookcase has a depth of 250-350, and a height of about 2000mm. [0003] The structure and function of the bookcase: [0004] 1. The chassis is generally segmented and combined, with docking and interchangeability. [0005] 2. Section type, frame height, frame width, number of layers and number of groups can be selected according to customer needs. [0006] 3. Powder: Electrostatic powder spraying, environmentally friendly, non-toxic, and odor...

Problems solved by technology

[0010] In order to solve the technical problem that the bookcase lacks a privacy control mechanism, the present invention provides a brushless DC motor control mechanism, based on the comparison of the partial variance of the gray value of each sub-image, multiple sub-images that need image enhancement processing are identified , and replace the enhanced multiple sub-images into the original image; on the basis of the processing of the white balance processing device and the morphological processing device, realize the directional and targeted extraction of the foreground image of the enhanced replacement image, for the follow-up The recognition and detection of images provide more valuable data to be analyzed; when the tailing phenomenon caused by jitter is detected, the image content is analyzed, specifically, the image is determined based on the values ​​of each red channel of each pixel of the image Displacement vector, and use the built-in motor of the hemispherical shooting mechanism to correct the corresponding displacement. On the basis of the above data processing, through the authentication of nearby personnel, the automatic switch control of the bookcase is realized.
