Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic site map making, and in particular relates to a photovoltaic site map making method based on a vector map. Background Art

[0002] Photovoltaic power stations can be divided into independent power generation systems with batteries and grid-connected power generation systems without batteries. Solar power generation is divided into solar thermal power generation and photovoltaic power generation. The solar power that has entered commercialization in the current period refers to solar photovoltaic power generation. Photovoltaic power generation products are mainly used in three aspects: one is to provide power for places without electricity; the second is solar daily electronic products, such as various solar chargers, solar street lights and various solar lawn lamps; the third is grid-connected power generation, which has been widely promoted and implemented in our country.

[0003] There are a large number of photovoltaic panels in a photovoltaic station, and the site environment is relatively complex. The existing satellite navigation technology can only navigate to the periphery of the photovoltaic station. As for the distribution of photovoltaic panels in the photovoltaic station, the existing satellite navigation device cannot accurately indicate the specific location, resulting in the station staff being unable to accurately locate the photovoltaic panels in the photovoltaic station, making it inconvenient for the photovoltaic station staff to repair the photovoltaic panels in the photovoltaic station, and even causing the photovoltaic station staff to be unable to find the location of the photovoltaic panels, which increases the labor intensity of the photovoltaic station staff.

[0004] Therefore, a method for making a photovoltaic site map based on a vector map is needed to solve the above-mentioned problems. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a method for making a photovoltaic site map based on a vector map, which effectively solves the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: a method for making a photovoltaic site map based on a vector map, the making method comprising the following steps:

[0007] S1. Make a base map: obtain the bottom-level topographic map, confirm the zoom level and the GPS coordinates of the center, find the location of the station from Google Maps, intercept the satellite map as the bottom-level topographic map, and confirm the scale range of Google Maps. Google Maps uses a tile map algorithm and records the GPS coordinates of the center point. Then use a self-made tool to automatically download the topographic tile map that can cover the entire station area, and automatically splice it to generate a complete large map;

[0008] S2. Obtaining detailed images of the station: Use the aerial image of the station to obtain the latest detailed image of the station, and then overlay it with the large image in the previous step to ensure that the center point and the magnification ratio are consistent, and finally obtain the base map of the map after fusion;

[0009] S3. Create a vector map of photovoltaic equipment: Use relevant intelligent software to create a site equipment vector layer on the upper layer of the map, including photovoltaic panels, inverters and all equipment that need maintenance or attention. According to the information provided by the site, enter the number, name, coordinates and other information of each photovoltaic panel in the vector map to prepare for future real-time status synchronization;

[0010] S4. Create a site path vector diagram: Based on the actual layout of photovoltaic panels at the site, use AI tools to draw a path vector diagram. The vector diagram includes walkable paths and impossible walkable areas, and can dynamically set prohibited areas when necessary. The path vector diagram will provide a data basis for the path-finding algorithm to ensure that every photovoltaic panel has a path to reach.

[0011] Furthermore, after the above steps, all the information and materials of the map are completed. The base map provides the basic pixel coordinates of the entire map, the GPS coordinates of the center point, and the zoom level. The Mercator projection algorithm can be used, combined with the tile map algorithm of Google Maps, and finally two functions are obtained:

[0012] xy_to_gps(x,y,level);

[0013] gps_to_xy(lng,lat,level);

[0014] The parameters x and y represent the pixel coordinates of the map, lng and lat are the GPS longitude and latitude coordinates, and level is the zoom level. With these two functions, you can convert the pixel coordinates of the map into GPS coordinates, or you can convert the GPS coordinates into pixel coordinates only.

[0015] Furthermore, after the above steps, the GPS coordinates of the user are mapped to the pixel coordinates on the map. Then, when we need to reach any destination on the map, as long as the pixel coordinates of the destination are combined with the previously prepared path information through the path-finding algorithm, the path-finding path can be calculated immediately and corrected in real time according to the user's current GPS coordinates.

[0016] Furthermore, after the above steps, the spatial index is used for query. When performing query operations, such as searching for map features within a specific range, the sub-areas that may contain the target are first quickly located through the spatial index, and then accurate matching and screening are performed in these sub-areas. When the map data changes, such as adding, deleting or modifying map objects, the spatial index is updated in a timely manner to ensure the accuracy and effectiveness of the index.

[0017] Furthermore, using spatial indexes for queries involves distance calculations between points, points and lines, points and polygons, etc. Common distance calculation methods include Euclidean distance: Where (x1, y1) and (x2, y2) are the coordinates of two points.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention, by making an internal map of the photovoltaic station, links the positions of photovoltaic panels in the photovoltaic station with the specific position coordinates of the staff, thereby achieving accurate positioning of the photovoltaic panels in the photovoltaic station, ensuring that the station staff can accurately locate the positions of the photovoltaic panels in the photovoltaic station, facilitating the photovoltaic station staff to repair the photovoltaic panels in the photovoltaic station, avoiding the phenomenon that the photovoltaic station staff cannot find the positions of the photovoltaic panels, reducing the labor intensity of the photovoltaic station staff and improving convenience.

Obviously, the described embodiments are only 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 ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Embodiment 1, by Figure 1 The present invention discloses a method for making a photovoltaic station map based on a vector map, and the making method comprises the following steps:

[0024] S1. Make a base map: obtain the bottom-level topographic map, confirm the zoom level and the GPS coordinates of the center, find the location of the station from Google Maps, intercept the satellite map as the bottom-level topographic map, and confirm the scale range of Google Maps. Google Maps uses a tile map algorithm and records the GPS coordinates of the center point. Then use a self-made tool to automatically download the topographic tile map that can cover the entire station area, and automatically splice it to generate a complete large map;

[0025] Specifically, there are 16 levels from large to small. Generally, level 16 is selected as the terrain material because it is the clearest and records the GPS coordinates of the center point;

[0026] S2. Obtaining detailed images of the station: Use the aerial image of the station to obtain the latest detailed image of the station, and then overlay it with the large image in the previous step to ensure that the center point and the magnification ratio are consistent, and finally obtain the base map of the map after fusion;

[0027] S3. Create a vector map of photovoltaic equipment: Use relevant intelligent software to create a site equipment vector layer on the upper layer of the map, including photovoltaic panels, inverters and all equipment that need maintenance or attention. According to the information provided by the site, enter the number, name, coordinates and other information of each photovoltaic panel in the vector map to prepare for future real-time status synchronization;

[0028] S4. Create a site path vector diagram: Based on the actual layout of photovoltaic panels at the site, use AI tools to draw a path vector diagram. The vector diagram includes walkable paths and impossible walkable areas, and can dynamically set prohibited areas when necessary. The path vector diagram will provide a data basis for the path-finding algorithm to ensure that every photovoltaic panel has a path to reach.

[0029] Specifically, after the above steps, all the information and materials of the map are completed. The base map provides the basic pixel coordinates of the entire map, the GPS coordinates of the center point, and the zoom level. The Mercator projection algorithm can be used, combined with the tile map algorithm of Google Maps, and finally two functions are obtained:

[0030] xy_to_gps(x,y,level);

[0031] gps_to_xy(lng,lat,level);

[0032] The parameters are x, y representing the pixel coordinates of the map, lng, lat are the GPS longitude and latitude coordinates, and level is the zoom level. With these two functions, you can convert the pixel coordinates of the map into GPS coordinates, or you can convert the GPS coordinates into pixel coordinates only. Level is the zoom level, which is 16 here.

[0033] Embodiment 2, by Figure 1 After the above steps, the GPS coordinates are mapped to the pixel coordinates on the map. Then, when we need to reach any destination on the map, as long as the pixel coordinates of the destination are combined with the previously prepared path information through the path-finding algorithm, the path-finding path can be calculated immediately and corrected in real time according to the user's current GPS coordinates.

[0034] Specifically, after the above steps, the spatial index is used for query. When performing query operations, such as searching for map features within a specific range, the sub-areas that may contain the target are first quickly located through the spatial index, and then accurate matching and screening are performed in these sub-areas. When the map data changes, such as adding, deleting or modifying map objects, the spatial index is updated in time to ensure the accuracy and effectiveness of the index;

[0035] Querying using spatial indexes involves distance calculations between points, points and lines, points and polygons, etc. Common distance calculation methods include Euclidean distance: Where (x1, y1) and (x2, y2) are the coordinates of two points. The recorded coordinate values ​​can be substituted into the formula to calculate the distance.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
