Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic technology, and specifically provides a node optimization method, system and storage medium for distributed photovoltaic power generation. Background Art

[0002] The node optimization of distributed photovoltaic power generation mainly includes maximizing the utilization of solar energy resources, reducing the failure rate of the system, and realizing the centralized management of the system. These optimization strategies help to improve the performance and economy of the distributed photovoltaic power generation system, ensure the stable operation of the system, and maximize the utilization of renewable energy resources.

[0003] The existing improvements in the node optimization for distributed photovoltaic power generation usually analyze the node voltage and the power in the photovoltaic power generation system, and optimize the access scheme of distributed photovoltaics by establishing a configuration model or a mathematical model, so as to improve the efficiency of photovoltaic power generation. Although this improvement method can greatly improve the conversion rate of light energy during actual photovoltaic power generation, if the orientation of the solar panels cannot be intelligently controlled, when the received light energy intensity is limited, even if the photovoltaic power generation efficiency is very high, there will still be a low upper limit of the power conversion amount, thus unable to fully utilize environmental resources. For example, in the Chinese patent with the application publication number CN112366703A, a multi-distributed photovoltaic grid-connected node optimization method and system are disclosed. This solution is to establish a comprehensive mathematical model for multi-distributed photovoltaic grid-connected node optimization; use the differential evolution invasive weed algorithm to optimize the comprehensive mathematical model to obtain the optimal multi-distributed photovoltaic access scheme. Although this method can select the optimal photovoltaic access scheme during photovoltaic power generation, there will still be a situation where the environmental resources cannot be fully utilized due to limited light energy reception, resulting in a low upper limit of the power conversion amount. In view of this, it is necessary to improve the existing node optimization method for distributed photovoltaic power generation. Summary of the Invention

Whenever a real-time shaded image is obtained, perform pixelization on the real-time shaded image, and based on the shadow gray value, obtain the area of the preferred shadow area within the shadow analysis circle, the area of the area to the left of the preferred shadow area within the shadow analysis circle, and the area of the area to the right of the preferred shadow area within the shadow analysis circle in the pixelized real-time shaded image, and record them as B2, B1, and B3 in sequence. Denote the array [B1, B2, B3] as the real-time light-chasing array, and denote the value of B1 minus B3 as the real-time side difference.

[0052] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0053] Embodiment 1, in the first aspect, please refer to Figure 1 As shown, the present application provides a node optimization system for distributed photovoltaic power generation, including an optimizable panel acquisition module, a standard light-tracking array extraction module, and an orientation adjustment module;

[0054] The optimizable panel acquisition module is used to analyze the positions of the solar panels for photovoltaic power generation, and obtain the optimizable panels based on the position analysis results.

[0055] In the specific implementation process, each node in the distributed photovoltaic power generation system includes a power generation system near users, a natural gas distributed energy project, a distributed photovoltaic system, and waste heat recovery and energy cascade utilization. The distributed photovoltaic system is an important part of the distributed power generation system. It converts solar energy into electrical energy through solar panels installed on the roofs of buildings or other appropriate positions. By optimizing the orientation of the solar panels, the upper limit of the electrical energy conversion of the distributed photovoltaic system can be effectively improved, thereby optimizing the distributed photovoltaic power generation system;

[0056] The optimizable panel acquisition module is configured with a panel screening unit, and the panel screening unit is configured with a panel screening strategy. The panel screening strategy includes: obtaining the top view in the design drawings of the solar panel, and obtaining the smallest rectangle that can enclose the top view in the plane rectangular coordinate system, denoted as the panel occupation rectangle;

[0057] In the specific implementation process, the method for obtaining the smallest rectangle can be: placing the top view in the plane rectangular coordinate system, using two straight lines parallel to the X-axis to translate to exactly coincide with the uppermost and lowermost sides of the top view, and then using two straight lines parallel to the Y-axis to translate to exactly coincide with the rightmost and leftmost sides of the top view. At this time, the enclosed area by the four straight lines is the smallest rectangle that can enclose the top view, that is, the panel occupation rectangle;

[0058] Establish a plane rectangular coordinate system, denoted as the node analysis coordinate system. The units of both the X-axis and Y-axis of the node analysis coordinate system are meters. Denote the area where the solar panels for photovoltaic power generation to be analyzed are located as the solar panel area. Mark the positions of each solar panel in the first quadrant of the node analysis coordinate system using panel occupancy rectangles based on the positional relationships of all solar panels within the solar panel area;

[0059] Denote the center of the panel occupancy rectangle as the panel occupancy center. For any three panel occupancy centers not on the same straight line, obtain the circles corresponding to the three panel occupancy centers, denoted as panel occupancy range circles; obtain all the panel occupancy range circles that can be obtained in the node analysis coordinate system;

[0060] In specific implementation, for example, during the analysis of the solar panel area, the obtained node analysis coordinate system is as Figure 2 shown. Among them, the rectangles corresponding to JJ1 to JJ4 are the panel occupancy rectangles corresponding to the solar panels within the solar panel area. Please refer to Figure 3 shown for the panel occupancy range circles obtained through analysis. Among them, CC1 to CC4 are all the panel occupancy range circles obtained based on JJ1 to JJ4. The calculated standard wrapping coefficients corresponding to CC1 to CC4 are 1.3, 2.5, 2.4, and 1.3 respectively. Then denote the center of the panel occupancy circle CC2 as the optimal center, and at the same time denote the panel occupancy rectangle JJ2 closest to the optimal center as the optimizable panel. The optimizable panel obtained in this embodiment is the solar panel at the center of the positions of all solar panels within the solar panel area during actual analysis. By analyzing the optimizable panel, the analysis result can fit all the solar panels within the solar panel area to the greatest extent. If a solar panel is randomly selected as the optimizable panel, when the leftmost or rightmost solar panel is selected, the analysis result may not effectively act on the rightmost or leftmost solar panel, thus failing to achieve the effect of increasing the upper limit of the overall power conversion amount;

[0061] For any panel occupancy range circle, denote the number of complete panel occupancy rectangles within the panel occupancy range circle as the first-level wrapping coefficient of the panel occupancy range circle. When the panel occupancy rectangle is on the circle of the panel occupancy range circle, denote the value obtained by dividing the area of the panel occupancy rectangle within the panel occupancy range circle by the area of the panel occupancy rectangle as the second-level wrapping coefficient. Denote the value obtained by adding the first-level wrapping coefficient and all the second-level wrapping coefficients as the standard wrapping coefficient of the panel occupancy range circle;

[0062] Obtain the standard wrapping coefficients corresponding to all the panel occupancy range circles, and denote the center of the panel occupancy range circle corresponding to the maximum value among all the standard wrapping coefficients as the optimal center;

[0063] Denote the solar panel corresponding to the panel occupancy rectangle where the panel occupancy center closest to the optimal center is located as the optimizable panel.

[0064] The standard light-tracking array extraction module is used to set up a sliding bracket for an optimizable solar panel using the bracket setting method and obtain a standard light-tracking array based on the sliding bracket.

[0065] The standard light-tracking array extraction module includes a sliding bracket establishment unit and an array extraction unit. The sliding bracket establishment unit is configured with a sliding bracket establishment strategy, which includes: setting up a sliding bracket for an optimizable solar panel using the bracket setting method.

[0066] The bracket setting method includes:

[0067] Mark the side of the optimizable solar panel facing the light as the sunny side, and the side of the optimizable solar panel facing away from the light as the shady side; mark the side parallel to the ground and closest to the ground in the shady side as the bottom edge, install a small remote-controlled pulley vertically downward at the midpoint of the bottom edge, and mark the width of the pulley as the wheel width; make a circle with the bottom edge as the diameter, denoted as the shady circle, and use bracket materials to make a circular bracket with the same size as the shady circle. Among them, the thickness of the circular edge of the circular bracket is greater than the wheel width, and a track for sliding the small remote-controlled pulley can be made in the circular edge of the circular bracket; embed the small remote-controlled pulley at the midpoint of the bottom edge into the circular bracket;

[0068] In the specific implementation process, for the establishment of the sliding bracket, please refer to Figure 4 as shown in the figure, where TT1 is the solar panel, YY1 is the small remote-controlled pulley at the midpoint of the bottom edge, YY2 and YY3 are the two small remote-controlled pulleys perpendicular to the ground corresponding to the top edge, SS1 is the center of the shady side, that is, the position where the camera can be installed through a universal wheel, GG2 is the sliding bracket, and GG1 is the track in the sliding bracket that allows the small remote-controlled pulley to slide; by establishing the sliding bracket, while analyzing the image corresponding to the shadow through the camera, the small remote-controlled pulley can be controlled to adjust the orientation of the solar panel, so that the adjusted orientation of the solar panel is more conducive to fully converting solar energy into electrical energy;

[0069] Mark the side parallel to the ground and farthest from the ground in the shady side as the top edge, install two telescopic brackets perpendicular to the ground at the two endpoints of the top edge, and install two small remote-controlled pulleys perpendicular to the ground at the other ends of the two telescopic brackets, embed the two small remote-controlled pulleys into the circular bracket, and mark the circular bracket with three small remote-controlled pulleys embedded as the sliding bracket.

[0070] The array extraction unit is configured with an array extraction strategy, which includes:

[0071] Install a camera through a universal wheel at the center of the shady side, adjust the telescopic bracket connected to the top edge so that the camera's shooting range can completely wrap the sliding bracket, and fix the universal wheel at this time;

[0072] When the optimizable solar panel is irradiated by sunlight, use a camera to take an image, which is recorded as a shadow analysis image. In the shadow analysis image, the circle corresponding to the sliding bracket is recorded as the shadow analysis circle, and the center of the shadow analysis circle is recorded as the shadow analysis point; perform pixelization processing on the shadow analysis image, which is recorded as a pixelized analysis image, and record the gray value of the shadow analysis point of the pixelized analysis image as the shadow gray value;

[0073] In the specific implementation process, for example, during the actual implementation, the image taken by the camera when the light energy conversion efficiency is the highest within the recording time of the camera is as Figure 5 shown. Among them, RR1 is the shadow analysis circle. The gray value of the pixel point corresponding to the center of the shadow analysis circle is obtained as 40. Then, through analysis, it is obtained that the gray values of all pixel points within the area QQ1 in the shadow analysis circle RR1 are 40. Therefore, the area QQ1 is the preferred shadow area, and the area of the area QQ1 is 1m 2 , the area of the area QQ2 is 0.1m 2 , the area of the area QQ3 is 0.15m 2 , then the standard light-tracking array is [0.1m 2 , 1m 2 , 0.15m 2 ; By obtaining the standard light-tracking array, the filling situation of the shadow of the solar panel when the light energy conversion efficiency is the highest in the shadow analysis circle can be digitized, which is conducive to adjusting the orientation of the solar panel based on the real-time filling situation of the shadow of the solar panel in the shadow analysis circle during subsequent adjustment, ensuring that the adjusted solar panel is more conducive to fully converting solar energy into electrical energy;

[0074] Use a camera to continuously record for the standard daylighting duration on a sunny day, and based on the photovoltaic power generation data and the camera recording, obtain the image taken by the camera when the light energy conversion efficiency is the highest within the recording time of the camera, which is recorded as the preferred image; perform pixelization processing on the preferred image, which is recorded as the preferred pixel image, and record the area where the pixel points with the gray value of the shadow gray value in the shadow analysis circle in the preferred pixel image as the preferred shadow area, record the area of the preferred shadow area as A2, record the area of the area to the left of the preferred shadow area in the shadow analysis circle as A1, record the area of the area to the right of the preferred shadow area in the shadow analysis circle as A3, record the array [A1, A2, A3] as the standard light-tracking array, and record the value obtained by subtracting A3 from A1 as the standard side difference.

[0075] In the specific implementation process, the standard daylighting duration can be set with reference to the duration during which the solar panel can actually effectively convert solar energy in a day during actual operation, and the standard daylighting duration can be adjusted according to the different regional environments where the solar panel is located. In this embodiment, the standard daylighting duration is set to 20 hours;

[0076] The orientation adjustment module is used to adjust the orientations of all solar panels within the area where the optimizable panels are located based on the obtained standard light-tracking array.

[0077] The orientation adjustment module includes a solar panel adjustment unit, and the solar panel adjustment unit is configured with a solar panel adjustment strategy, and the solar panel adjustment strategy includes:

[0078] When the optimizable panel is in an operating state, a camera is used to take a picture every standard shooting duration, and the latest taken image is recorded as the real-time shaded image. Whenever a real-time shaded image is obtained, pixelization processing is performed on the real-time shaded image, and based on the shadow gray value, the area of the preferred shadow area within the shadow analysis circle, the area of the area to the left of the preferred shadow area within the shadow analysis circle, and the area of the area to the right of the preferred shadow area within the shadow analysis circle in the pixelized real-time shaded image are obtained, and are recorded as B2, B1, and B3 in sequence. The array [B1, B2, B3] is recorded as the real-time light-tracking array, and the value of B1 minus B3 is recorded as the real-time side difference.

[0079] In an actual application, the standard light-tracking array is [0.1m 2 , 1m 2 , 0.15m 2 , the standard side difference is -0.05m 2 , the real-time light-tracking array corresponding to the real-time shadow is [0.3m 2 , 0.95m 2 , 0m 2 , the real-time side difference is 0.3m 2 , then at this time the real-time side difference is greater than the standard side difference, indicating that the sunlight area on the left within the shadow analysis circle is larger at this time. Therefore, the solar panel should be rotated clockwise at this time, that is, control the three small remote control pulleys embedded in the sliding bracket to slide clockwise, so that the sunny side of the solar panel is fully in contact with the sunlight on the left. At the same time, by obtaining |A1 - B1| + |A3 - B3| and using the side difference sliding coordinate system to draw a curve, ensure that the power conversion amount of the solar panel is closest to the power conversion amount at the highest light energy conversion efficiency when the small remote control pulley stops;

[0080] Establish a plane rectangular coordinate system, denoted as the side difference sliding coordinate system. Among them, the X-axis of the side difference sliding coordinate system is the length, and the corresponding value of the Y-axis is |A1 - B1| + |A3 - B3|; record the positions where the three small control pulleys are located as the initial positions;

[0081] When the real-time side difference is greater than the standard side difference, control the three small remote-controlled pulleys embedded in the sliding bracket to slide clockwise. When starting to slide, draw a curve in the side-difference sliding coordinate system based on the sliding distance and the value of |A1 - B1| + |A3 - B3|, which is recorded as the positive sliding curve. When the slope of the intersection point of the positive sliding curve and the Y-axis is less than or equal to 0, obtain the rightmost point of the positive sliding curve in real time, and stop the sliding of the small remote-controlled pulleys when the slope of the rightmost point is 0; when the slope of the intersection point of the positive sliding curve and the Y-axis is greater than 0, control all the small remote-controlled pulleys embedded in the sliding bracket to slide counterclockwise, and draw a curve in the side-difference sliding coordinate system after starting to slide, which is recorded as the reverse sliding curve. When the slope of the intersection point of the reverse sliding curve and the Y-axis is greater than 0, control all the small remote-controlled pulleys to stop sliding; when the slope of the intersection point of the reverse sliding curve and the Y-axis is less than or equal to 0, obtain the rightmost point of the reverse sliding curve in real time, and stop the sliding of all the small remote-controlled pulleys when the slope of the rightmost point is 0;

[0082] In a practical application, the standard light-tracking array is [0.1m 2 , 1m 2 , 0.15m 2 , the standard side difference is -0.05m 2 , the real-time light-tracking array is [0.3m 2 , 0.95m 2 , 0m 2 , the real-time side difference is 0.3m 2 , then at this time the real-time side difference is greater than the standard side difference and the sunlight area on the left side within the shadow analysis circle is larger. Control the three small remote-controlled pulleys embedded in the sliding bracket to slide clockwise. When starting to slide, the obtained positive sliding curve is shown in Figure 6 . Among them, the slope of point PP1 is less than 0, indicating that |A1 - B1| + |A3 - B3| is decreasing, that is, the shadow analysis circle at this time is approaching the shadow analysis circle when the light energy conversion efficiency is the highest. Therefore, the electric energy conversion amount of the solar panel is increasing at this time. When the positive sliding curve extends to point PP2, the slope of point PP2 is 0, indicating that the difference between B1 and B3 and A1 and A3 in the real-time light-tracking array corresponding to the shadow analysis circle at this time is the minimum under the sunlight at this time. When continuing to slide the small remote-controlled pulleys, it will cause the sunlight area on the right side within the shadow analysis circle to increase, which is not conducive to the sunlight collection of the solar panel. Therefore, stop the sliding of all the small remote-controlled pulleys when the slope of the rightmost point of the positive sliding curve is 0;

[0083] When the real-time lateral difference is less than the standard lateral difference, control the three small remote control pulleys embedded in the sliding bracket to slide counterclockwise. When starting to slide, draw a curve in the lateral difference sliding coordinate system based on the sliding distance and the value of |A1 - B1| + |A3 - B3|, which is recorded as the positive sliding curve. When the slope of the intersection point of the positive sliding curve and the Y-axis is less than or equal to 0, obtain the rightmost point of the positive sliding curve in real time, and stop the sliding of the small remote control pulleys when the slope of the rightmost point is 0; when the slope of the intersection point of the positive sliding curve and the Y-axis is greater than 0, control all the small remote control pulleys embedded in the sliding bracket to slide clockwise, and draw a curve in the lateral difference sliding coordinate system after starting to slide, which is recorded as the reverse sliding curve. When the slope of the intersection point of the reverse sliding curve and the Y-axis is greater than 0, control all the small remote control pulleys to stop sliding; when the slope of the intersection point of the reverse sliding curve and the Y-axis is less than or equal to 0, obtain the rightmost point of the reverse sliding curve in real time, and stop all the small remote control pulleys when the slope of the rightmost point is 0;

[0084] In the specific implementation process, when the slope of the positive sliding curve or the reverse sliding curve is greater than 0, it indicates that |A1 - B1| + |A3 - B3| is increasing, that is, the gap between the current shadow analysis circle and the shadow analysis circle at the highest light energy conversion efficiency is increasing, which is not conducive to the lighting of the solar panel, that is, the power conversion amount of the solar panel at this time is decreasing. Therefore, if the slope of the positive sliding curve is greater than 0, the rotation direction of the small remote control pulleys should be changed immediately. If the slope of the reverse sliding curve is greater than 0 at this time, it means that no matter how the solar panel is rotated, the power conversion amount will decrease. Therefore, at this time, all the small remote control pulleys should be controlled to stop sliding, and the solar panel should be operated in the current orientation;

[0085] When the real-time lateral difference is equal to the standard lateral difference, do not control the small control pulleys;

[0086] In the specific implementation process, when the real-time lateral difference is equal to the standard lateral difference, it indicates that the current real-time image is basically the same as the preferred image, and the light energy conversion efficiency of the solar panel is the highest. Therefore, there is no need to adjust the orientation of the solar panel;

[0087] When the small control pulleys slide and the positions where the three small control pulleys stop sliding are not the initial positions, adjust the orientations of all the solar panels in the solar panel area to be the same as the orientation of the optimizable panel;

[0088] In the specific implementation process, when adjusting the orientation of the optimizable panel, the orientations of all the solar panels in the solar panel area should be adjusted correspondingly, so as to improve the power conversion amount of all the solar panels in the solar panel area;

[0089] When the small control pulley slides and the positions where the three small control pulleys stop sliding are the initial positions, or when the small control pulley does not slide, the orientation of the solar panel is not adjusted.

For any three panel occupation centers that are not on the same straight line, obtain the circle corresponding to the three panel occupation centers, denoted as the panel occupation range circle; obtain all the panel occupation range circles that can be obtained in the node analysis coordinate system;

[0095] For any one panel occupation range circle, denote the number of complete panel occupation rectangles within the panel occupation range circle as the first-level wrapping coefficient of the panel occupation range circle. When the panel occupation rectangle is on the circle of the panel occupation range circle, denote the value obtained by dividing the area of the panel occupation rectangle within the panel occupation range circle by the area of the panel occupation rectangle as the second-level wrapping coefficient. Denote the value obtained by adding the first-level wrapping coefficient and all the second-level wrapping coefficients as the standard wrapping coefficient of the panel occupation range circle;

[0096] Obtain the standard wrapping coefficients corresponding to all the panel occupation range circles, and denote the center of the panel occupation range circle corresponding to the maximum value among all the standard wrapping coefficients as the optimal center;

Among them, the thickness of the circular edge of the circular bracket is greater than the wheel width, and a track for embedding and sliding the small remotely controlled pulley is made in the circular edge of the circular bracket; embed the small remotely controlled pulley at the midpoint of the bottom edge into the circular bracket.

[0102] Mark the side parallel to the ground and farthest from the ground in the shady side as the top edge, install two telescopic brackets perpendicular to the ground at the two endpoints of the top edge, and install two small remotely controlled pulleys perpendicular to the ground at the other ends of the two telescopic brackets, embed the two small remotely controlled pulleys into the circular bracket, and denote the circular bracket with three small remotely controlled pulleys embedded as the sliding bracket.

[0104] Step S202 includes:

[0105] Step S2021, install a camera at the center of the shady side through a universal wheel, adjust the telescopic bracket connected to the top edge so that the camera's shooting range can completely cover the sliding bracket, and fix the universal wheel at this time;

[0106] Step S2022, when the optimizable solar panel is irradiated by sunlight, use the camera to take an image, denoted as the shadow analysis image. In the shadow analysis image, mark the circle corresponding to the sliding bracket as the shadow analysis circle, and mark the center of the shadow analysis circle as the shadow analysis point; perform pixelization processing on the shadow analysis image, denoted as the pixelized analysis image, and denote the gray value of the shadow analysis point in the pixelized analysis image as the shadow gray value;

[0107] In step S2023, use a camera to continuously record for the standard daylighting duration on a sunny day, and based on the photovoltaic power generation data and the camera recording, obtain the image captured by the camera with the highest light energy conversion efficiency during the recording time of the camera, denoted as the preferred image; perform pixelation processing on the preferred image, denoted as the preferred pixel image, and denote the area where the pixel points with the shadow gray value in the shadow analysis circle in the preferred pixel image as the preferred shadow area, denote the area of the preferred shadow area as A2, denote the area of the area to the left of the preferred shadow area in the shadow analysis circle as A1, denote the area of the area to the right of the preferred shadow area in the shadow analysis circle as A3, denote the array [A1, A2, A3] as the standard light-tracking array, and denote the value obtained by subtracting A3 from A1 as the standard side difference.

[0109] Step S3 includes: Step S301, when the optimizable panels are in the operating state, use the camera to take a picture every standard shooting duration, and denote the latest captured image as the real-time shadow image. Whenever a real-time shadow image is obtained, perform pixelation processing on the real-time shadow image, and based on the shadow gray value, obtain the area of the preferred shadow area in the shadow analysis circle, the area of the area to the left of the preferred shadow area in the shadow analysis circle, and the area of the area to the right of the preferred shadow area in the shadow analysis circle in the pixelated real-time shadow image, denoted as B2, B1, and B3 in sequence. Denote the array [B1, B2, B3] as the real-time light-tracking array, and denote the value obtained by subtracting B3 from B1 as the real-time side difference.

[0110] Step S302, establish a plane rectangular coordinate system, denoted as the side-difference sliding coordinate system. Among them, the X-axis of the side-difference sliding coordinate system is the length, and the value corresponding to the Y-axis is |A1 - B1| + |A3 - B3|; denote the positions of the three small control pulleys as the initial positions;

[0111] Step S303, when the real - time side difference is greater than the standard side difference, control the three small remote - controlled pulleys embedded in the sliding bracket to slide clockwise. When starting to slide, draw a curve in the side - difference sliding coordinate system based on the sliding distance and the value of |A1 - B1|+|A3 - B3|, denoted as the positive - sliding curve. When the slope of the intersection point of the positive - sliding curve and the Y - axis is less than or equal to 0, obtain the right - most point of the positive - sliding curve in real - time, and stop the sliding of the small remote - controlled pulleys when the slope of the right - most point is 0; when the slope of the intersection point of the positive - sliding curve and the Y - axis is greater than 0, control all the small remote - controlled pulleys embedded in the sliding bracket to slide counter - clockwise, and draw a curve in the side - difference sliding coordinate system after starting to slide, denoted as the reverse - sliding curve.

When the slope of the intersection point of the positive - sliding curve and the Y - axis is less than or equal to 0, obtain the right - most point of the positive - sliding curve in real - time, and stop the sliding of the small remote - controlled pulleys when the slope of the right - most point is 0; when the slope of the intersection point of the positive - sliding curve and the Y - axis is greater than 0, control all the small remote - controlled pulleys embedded in the sliding bracket to slide clockwise, and draw a curve in the side - difference sliding coordinate system after starting to slide, denoted as the reverse - sliding curve.
