Embodiment 1

[0051] according to image 3 As shown, the screen is divided into five areas A, B, C, D, and E, and the resolution is 800×480. Area A range: upper right corner coordinates (0, 0), lower right corner left (0+a, 0+b); B area range: upper right corner coordinates (800-a, 0), lower right corner left (800, 0+b) ); C area range: upper right corner coordinates (800-a, 480-b), lower right corner left (800, 480); D area range: upper right corner coordinates (0, 480-b), lower right corner left (0+a , 480); E area range: upper right corner coordinates (0+a, 0+b), lower right corner left (800-a, 480-b);

[0052] Wherein, a and b are the x-axis length and y-axis length of the area demarcated by the four corners, which can be adjusted according to the screen size.

[0053] Click to trigger the calibration rule Description: from image 3 Any one of the areas A, B, C, and D shown in the division area in , first clockwise, then counterclockwise, then click the center area, or first counterc...

Abstract

The present invention provides a charging controller LCD screen calibration triggering method, system and device and a medium, the screen calibration is triggered through clicking according to the specified sequence at the specific position, the safety risk and operation complexity of opening a charging cabinet door are eliminated, the professionality of the screen calibration operation is reduced, the convenience of replying and processing the problem that the touch screen cannot be operated due to inaccurate touch points is improved, the maintainability of the product is improved, and the operation and maintenance cost is reduced. Calibration is triggered according to the fact that the touch point is clicked into different areas, calibration accuracy is greatly improved, each area is adjusted according to the screen size, and calibration efficiency is improved conveniently; and the coordinates of an existing screen are not accurate, due to screen position deviation or replacement of a new screen and overturning of original point positions of screens of different manufacturers, the method can achieve calibration triggering of different original point positions in the screen, and for original point deviation, due to the fact that area delimitation is only one range, large deviation can be covered, and specific coordinate points are not limited.

Description

technical field [0001] The invention relates to the field of intelligent control of chargers, in particular to a charging controller LCD screen calibration triggering method, system, equipment and medium. Background technique [0002] The centralized controller of the charging system is the core of the system operation, and the human-computer interaction function is completed through the LCD touch screen. Due to slight changes in the capacitance or conversion circuit of the LCD screen during use, the position will be shifted, the contacts will be inaccurate, and it needs to be recalibrated. Due to the high voltage in the charging pile cabinet, in order to recalibrate the touch screen safely and quickly, a charging controller LCD screen calibration trigger method, system, equipment and medium are proposed. Contents of the invention [0003] Aiming at the problems in the prior art that the LCD screen needs to be recalibrated due to slight changes in the capacitance or the c...
