Description

Technical Field

[0001] The present invention relates to the field of charging piles, and more specifically, to a charging pile with an identification function. Background Art

[0002] As the energy supply system of electric vehicles, the charging performance of electric vehicle charging piles is related to the service life and charging time of the battery pack. This is also one of the aspects that consumers are most concerned about before buying electric vehicles. The basic principle of electric vehicle charger design is to achieve fast, efficient, safe and reasonable power supply to power batteries. In addition, the applicability of chargers to various power batteries must also be considered. Charging piles (plugs) can be divided into DC charging piles (plugs), AC charging piles (plugs) and AC / DC integrated charging piles (plugs).

[0003] However, the charging wires of the charging pile have a certain discharge property during the charging process. If the charging wires come into contact with the human body, especially the human legs, it is easy to cause discharge accidents to the human body. This will damage the charging pile to which the charging wires belong and cause personal injury to nearby people. Summary of the invention

[0004] In order to solve the technical problems in related fields, the present invention provides a charging pile with an identification function, which can determine that the human legs are blocked by the charging wires and issue a first analysis instruction when the ratio of the number of curvature values ​​in the second curvature set that is the same as the first curvature set to the number of curvature values ​​in the first curvature set exceeds or is equal to the set ratio threshold and there is an overlapping part in the imaging blocks occupied by the human legs and the charging wires in the on-site optimized image. Otherwise, it can determine that the human legs are not blocked by the charging wires and issue a second analysis instruction, thereby providing reliable reference information for subsequent photoelectric alarm operations and effectively reducing the probability of safety accidents caused by discharge to the human body on site.

[0005] According to the present invention, a charging pile with an identification function is provided, comprising a charging pile body and a charging pile scene identification system connected to the charging pile body, the charging pile scene identification system comprising: A mode switching mechanism is provided in the charging pile and is used to switch the current mode of the photoelectric monitoring mechanism from the power saving mode to the working mode when it is detected that the charging pile is in the charging process, and to switch the current mode of the photoelectric monitoring mechanism from the working mode to the power saving mode when it is detected that the charging pile exits the charging process; A photoelectric monitoring mechanism, connected to the mode switching mechanism, is disposed opposite the charging pile and is used to perform a photoelectric sensing action facing the charging scene when in the working mode, so as to obtain and output a corresponding charging scene image; A directional blurring device, connected to the photoelectric monitoring mechanism, for performing directional blurring processing on the received charging scene image to obtain and output a corresponding directional blurring image; An affine transformation device, connected to the directional blur device, for performing affine transformation processing on the received directional blur image to obtain and output a corresponding affine transformation image; a band-stop filtering device, connected to the affine transformation device, for performing a band-stop filtering process on the received affine transformation image to obtain and output a corresponding band-stop filtered image; A set parsing device, connected to the band-stop filter device, used to obtain each curvature value of the standard contour curve of the human leg to obtain a first curvature set, identify the imaging block of the human leg based on the color imaging characteristics of the human leg in the received band-stop filter image, and obtain each curvature value of the edge curve of the imaging block to obtain a second curvature set, when the ratio of the number of curvature values ​​in the second curvature set that is the same as the first curvature set to the number of curvature values ​​in the first curvature set exceeds or equals to a set ratio threshold and there is an overlapped portion in the imaging blocks respectively occupied by the human leg and the charging cable in the received band-stop filter image, it is determined that the human leg is blocked by the charging cable and a first parsing instruction is issued; otherwise, it is determined that the human leg is not blocked by the charging cable and a second parsing instruction is issued; a photoelectric alarm device connected to the collective analysis device, and configured to execute a state alarm action corresponding to a human body touching the charging wire during charging when the first analysis instruction is received, and to stop executing a state alarm action corresponding to a human body touching the charging wire during charging when the second analysis instruction is received; The collective analysis device is further used to identify the imaging blocks of the charging cable based on the color imaging characteristics of the charging cable.

[0006] Therefore, the present invention has at least the following beneficial technical effects: First, the curvature values ​​of the standard contour curve of the human leg are obtained to obtain a first curvature set, the imaging blocks of the human leg are identified based on the color imaging characteristics of the human leg in the received band-stop filter image, and the curvature values ​​of the edge curves of the imaging blocks are obtained to obtain a second curvature set, thereby providing key data for whether the human leg is subsequently blocked by the charging wire; Second: when the ratio of the number of curvature values ​​in the second curvature set that are the same as the first curvature set to the number of curvature values ​​in the first curvature set exceeds or equals the set ratio threshold and there is an overlap between the imaging blocks respectively occupied by the human legs and the charging wires in the received band-stop filter image, it is determined that the human legs are blocked by the charging wires and a first parsing instruction is issued; otherwise, it is determined that the human legs are not blocked by the charging wires and a second parsing instruction is issued; Third: The photoelectric alarm device is used to execute the status alarm action corresponding to the human body touching the charging wire during the charging process of the charging pile when the first analysis instruction is received, and is also used to stop executing the status alarm action corresponding to the human body touching the charging wire during the charging process of the charging pile when the second analysis instruction is received, thereby reducing the probability of discharge accidents of the charging pile.

[0007] The charging pile with identification function of the present invention is easy to operate and stable in operation. Since a targeted visual analysis mechanism can be used to intelligently judge whether the legs of a person at the charging site are blocked by the charging wire and decide whether to perform a corresponding photoelectric alarm operation, the safety and reliability of the charging site are improved.
