Detailed implementation manners The following further describes the present invention in detail with reference to specific embodiments, but the implementation manners of the present invention are not limited thereto. In order to accurately, efficiently, and automatically perform connection rib-related inspections after the PCB layout design is completed, an embodiment of the present invention provides a method, device, equipment, and medium for identifying connection ribs in a PCB panel. It should be noted that the execution subject of a method for identifying connection ribs in a PCB panel provided by an embodiment of the present invention can be a device for identifying connection ribs in a PCB panel, and the device can run in an electronic device. Among them, the electronic device can be a server or a terminal device, of course, it is not limited thereto. Optionally, the method of an embodiment of the present invention can be implemented by a processor or a processing module in a computer, and this implementation process can be associated with PCB design to achieve code conversion. Of course, the identification method can also be embedded in PCB design-related software and presented in the form of a plugin, and these are all reasonable. To facilitate understanding of the solution of the embodiment of the present invention, the algorithms involved in the method for identifying connection ribs in a PCB panel are briefly introduced first. (1) Algorithm for calculating the vector coordinates of the closed graphic outline: For any polygon, obtain the coordinates of each vertex A1(x 1 , y 1 ), A2(x 2 , y 2 ),......, An(x n , y n ), then the area of this polygon is: Where S represents the area, x i represents the abscissa of the i-th vertex, y i represents the ordinate of the i-th vertex, and n represents the total number of vertices of the polygon. (2) Collision calculation algorithm: Compare the graphics 1 and 2 through physical-level coincidence, and then obtain the overlapping part. The overlapping part is the collision part, and the area of the collision part can be calculated by using the algorithm for calculating the vector coordinates of the graphic outline. First, introduce the sets and overlapping areas involved in the present invention. The first set is the set composed of all the closed graphic contours in the PCB design file; the second set is the set composed of all the remaining closed graphic contours after removing the outermost closed graphic contour from the first set if there is a double-contour process edge; the third set is the set composed of all the closed graphic contours after removing the component closed graphic contours or the silk-screen character closed graphic contours from the second set; the fourth set is the set composed of the first type of closed graphic contours in the third set, that is, the set composed of the component closed graphic contours or the silk-screen character closed graphic contours; the fifth set is the set composed of the other closed graphic contours in the third set, and this set will be continuously iteratively updated; the sixth set is the set composed of the PCB closed graphic contours in the fourth set, and this set will be continuously iteratively updated; the seventh set is the set composed of the collision closed graphic contours selected from the fifth set. The first overlapping area is the overlapping area between two closed graphic contours in the first set; the second overlapping area is the overlapping area within each combination of the screened closed graphic contours and the closed graphic contours in the third set; the third overlapping area is the overlapping area between two closed graphic contours in the fourth set; the fourth overlapping area is the overlapping area within each combination of the closed graphic contours in the fifth set and the closed graphic contours in the sixth set. The above descriptions such as the first, second, and third are for the purpose of facilitating the distinction of the described objects and do not impose any restrictions on the set content or the overlapping area. Next, in combination with the above content, the specific details of the solution of the present invention will be introduced in detail. In a first aspect, an embodiment of the present invention provides a method for identifying connection ribs in a PCB panel. As shown in FIG. 1, the method includes: S100, read in the PCB design file and obtain all the closed graphic contours of the same layer from the PCB design file; Specifically, the PCB design file includes contour information and object information; the contour information includes the closed graphic contours of each layer and the vector coordinates of each closed graphic contour; the object information includes component information and / or silk-screen character information; the component information includes component reference designators, component coordinates, and component sizes; the silk-screen character information includes character content, character coordinates, and character sizes. In an optional embodiment, obtaining all the closed graphic contours of the same layer from the PCB design file may include the following steps: 1) Obtain all the closed graphic contours of the same layer and the vector coordinates of each closed graphic contour from the PCB design file. It should be noted that: The PCB design file is generally a multi-layer PCB board, and the layers are connected by wires. There may be multiple closed graphic contours on the same layer. For example, the outermost large board, the small boards contained in the large board, and there may be closed graphic contours formed by silk printing or / and closed graphic contours formed by components in each area of the small boards. Obtaining the vector coordinates of each closed graphic contour on the same layer during the process of identifying the connecting ribs can save the time for subsequent collision calculations. S200. Combine all the closed graphic contours on the same layer in pairs for collision calculation, and determine the inclusion relationship between the two closed graphic contours in each group during the collision. In this step, for the closed graphic contours on the same layer, the closed graphic contours can be combined in pairs to check whether there is an overlap, that is, to determine whether a collision has occurred between the two. There are two situations: a collision has occurred or no collision has occurred between the two. And when a collision occurs, there will be a situation of complete coverage or partial overlap. Complete coverage means that one closed graphic contour is contained in another closed graphic contour, and partial overlap means that there is an overlapping area between one closed graphic contour and another closed graphic contour. This step needs to determine the inclusion relationship between the two closed graphic contours in each group during the collision, so as to quickly eliminate the areas where there may be no connecting ribs from the inclusion relationship and narrow the scope of the next identification. In an optional embodiment, the combining all the closed graphic contours on the same layer in pairs for collision calculation and determining the inclusion relationship between the two closed graphic contours in each group during the collision may include the following steps: 1) Number all the closed graphic contours and store them in the first set. 2) Combine all the closed graphic contours in the first set in pairs for collision calculation; if a collision occurs, calculate the first overlapping area of the two closed graphic contours in this group according to the respective vector coordinates of the two closed graphic contours in this group. Exemplarily, in the present invention, all the closed graphic contours in the first set are combined in pairs. Exemplarily: There are 1, 2, 3, 4 closed graphic contours in the first set, and the arrangement of combining them in pairs has types, that is, 1 and 2 in a group, 1 and 3 in a group, 1 and 4 in a group, 2 and 3 in a group, 2 and 4 in a group, 3 and 4 in a group, etc., a total of 5 situations. For each group of closed graphic contours, collision calculation is performed within the group. For example, collision calculation is performed between closed graphic contour 01 and closed graphic contour 02. The collision area can be obtained according to the respective vector coordinates of the two closed graphic contours in this group during the collision calculation, that is, the first overlapping area. The collision area calculation process can calculate the collision area by using the collision calculation algorithm introduced above. 3) For any set of closed graphic contours combined from the first set, determine the inclusion relationship between the two closed graphic contours in the set according to the first overlapping area of the two closed graphic contours in the set. This step can be applied to any set of closed graphic contours obtained by combining the first set. If the first overlapping area of the two closed graphic contours in the set is equal to the area of one of the closed graphic contours in the set, it is confirmed that the two closed graphic contours in the set have an inclusion relationship; if the first overlapping area is not equal to the area of any of the closed graphic contours in the set, it is confirmed that the two closed graphic contours in the set do not have an inclusion relationship. Exemplarily, for example, for the combination of closed graphic contour 01 and closed graphic contour 02, if the first overlapping area of the two is equal to the area of one of the closed graphic contours in the set; for example, the area of closed graphic contour 02, record the closed graphic contour 01 in the set and note that closed graphic contour 01 contains closed graphic contour 02; until the judgment of all sets of encapsulated graphic contours is completed; if the first overlapping area is not equal to the area of one of the closed graphic contours in the set, continue to judge the next set of closed graphic contours. If the combination of closed graphic contour 01 and closed graphic contour 02 does not collide, continue to judge the next set of closed graphic contours until the judgment of all sets of closed graphic contours in the first set is completed. S300. According to the inclusion relationship between the two closed graphic contours in each set, screen out the closed graphic contours that meet the inclusion relationship requirements from all the closed graphic contours; If there are double-contour process edges on the PCB board, the outermost closed graphic contour edge needs to be removed. The main purpose of this step is to delete the outermost closed graphic contour edge according to the inclusion relationship of the closed graphic contours, that is, to remove the large closed graphic contour, further narrow the recognition range of the connection ribs, and improve the accuracy. In an optional implementation manner, the screening out of the closed graphic contours that meet the inclusion relationship requirements from all the closed graphic contours according to the inclusion relationship between the two closed graphic contours in each set includes: 1) According to the inclusion relationship of any set of closed graphic contours obtained by combining the first set, count the closed graphic contours included in all the closed graphic contours in the first set; 2) If there are two closed graphic contours in the first set that contain the same remaining closed graphic contours, and it is confirmed that the areas of the two closed graphic contours are not equal; 3) Among the two closed graphic contours with unequal areas, delete the closed graphic contour with the larger area and retain the closed graphic contour with the smaller area; 4) Store the retained closed graphic contour and the included remaining closed graphic contours into the second set; 5) If there are no two closed graphic contours in the first set that contain the same remaining closed graphic contours, then store all the closed graphic contours in the first set into the second set. This step counts the closed graphic contours contained in all the closed graphic contours in the first set, that is, whether there is an inclusion relationship between two closed graphic contours in each group. If there are two closed graphic contours that contain the same remaining closed graphic contours and the areas of these two closed graphic contours are not equal, then delete the closed graphic contour with the larger area among these two closed graphic contours, retain the closed graphic contour with the smaller area among these two closed graphic contours, and store it together with the remaining closed graphic contours into the second set; if there are no two closed graphic contours that contain the same remaining closed graphic contours, then store all the closed graphic contours in the first set into the second set. S400, classify all the closed graphic contours that meet the inclusion relationship requirements into PCB closed graphic contours or other closed graphic contours; This step needs to further screen and determine PCB closed graphic contours and other closed graphic contours after completing the screening of the double contour process edges. Before screening, it is necessary to first determine the closed graphic contours containing components or the closed graphic contours of silk screen characters. In an optional implementation manner, the classifying all the closed graphic contours that meet the inclusion relationship requirements into PCB closed graphic contours or other closed graphic contours includes: 1) If the PCB design file contains component information, then obtain the component closed graphic contours from the PCB design file by using the component information; 2) If the PCB design file does not contain component information, then determine whether the PCB design file contains silk screen character information. If it contains, then obtain the silk screen character closed graphic contours from the PCB design file by using the silk screen character information; It should be noted that: the priority of component information is higher than that of silk screen character information. If the PCB design file has component information, it is preferred to use the component information to obtain the component closed graphic contours from the PCB design file and define the PCB closed graphic contours from the second set; if it does not contain component information, then further determine whether there is silk screen character information. If there is, then obtain the silk screen character closed graphic contours from the PCB design file through the silk screen character information and define the PCB closed graphic contours from the second set. Otherwise, the connecting ribs cannot be recognized. 3) Classify all the closed graphic contours that meet the inclusion relationship requirement into PCB closed graphic contours or other closed graphic contours according to the positional relationship between the closed graphic contour of the component or the closed graphic contour of the silk-screened character and the closed graphic contour that meets the inclusion relationship requirement. It should be noted that: The closed graphic contour containing components or silk-screened characters cannot be a connecting rib. It is necessary to screen out the closed graphic contours containing the closed graphic contour of the component or the closed graphic contour of the silk-screened character according to the positional relationship between the closed graphic contour of the component or the closed graphic contour of the silk-screened character and the closed graphic contours in the second set. This step uses representative components or silk-screened characters to screen the closed graphic contours, further narrowing the recognition range of the connecting rib, and can improve the accuracy of recognizing the connecting rib. In an alternative embodiment, referring to FIG. 2, according to the positional relationship between the closed graphic contour of the component or the closed graphic contour of the silk-screened character and the closed graphic contour that meets the inclusion relationship requirement, all the closed graphic contours that meet the inclusion relationship requirement are classified into PCB closed graphic contours or other closed graphic contours includes: 31) Use the component information or the silk-screened character information as the screening information, and use the closed graphic contour of the component or the closed graphic contour of the silk-screened character as the screening closed graphic contour; the screening information corresponds to the screening closed graphic contour one by one; It should be noted that: The screening information is component information or silk-screened character information. If the screening information is component information, the screening closed graphic contour is the closed graphic contour of the component; if the screening information is the closed graphic contour of the silk-screened character, the screening closed graphic contour is the closed graphic contour of the silk-screened character. In the subsequent process, use the screening information to further screen the closed graphic contours in the second set to further improve the accuracy of connecting rib recognition. 32) Remove the screening closed graphic contour from all the closed graphic contours that meet the inclusion relationship requirement, and store the remaining closed graphic contours in the third set; 33) Combine the screening closed graphic contour and the closed graphic contours in the third set in pairs for collision calculation. If there is no collision, confirm that the closed graphic contour belonging to the third set in this group is an other closed graphic contour; if there is a collision, calculate the second overlapping area of the two closed graphic contours in this group according to the screening information corresponding to the screening closed graphic contour and the vector coordinates of the closed graphic contours in the third set; 34) For any set of closed graphic contours formed by combining the screened closed graphic contours with the closed graphic contours in the third set, determine whether the closed graphic contours in the third set in this set are the first type of closed graphic contours or other closed graphic contours according to the second overlapping area of the two closed graphic contours in this set; The main function of using the screened closed graphic contours to screen the closed graphic contours in the third set is to determine the closed graphic contours that do not contain component closed graphic contours or silk-screen character closed graphic contours from the third set and regard them as other closed graphic contours, while for those that contain, the overlapping area needs to be further confirmed to determine whether they are the first type of closed graphic contours or other closed graphic contours. In this step, for any set of closed graphic contours formed by combining the screened closed graphic contours with the closed graphic contours in the third set, if the second overlapping area of the two closed graphic contours in this set is greater than 0, confirm that the closed graphic contours in the third set in this set are the first type of closed graphic contours; if the second overlapping area is equal to 0, confirm that the closed graphic contours in the third set in this set are other closed graphic contours. 35) Store the first type of closed graphic contours in the fourth set and store the other closed graphic contours in the fifth set; 36) Combine the closed graphic contours in the fourth set in pairs for collision calculation. If there is no collision, determine the two closed graphic contours in this set as PCB closed graphic contours and store them in the sixth set; if there is a collision, calculate the third overlapping area of the two closed graphic contours in this set according to their respective vector coordinates, and for any set of two closed graphic contours formed by combining the closed graphic contours in the fourth set, divide the two closed graphic contours in this set into PCB closed graphic contours or other closed graphic contours according to the third overlapping area of the two closed graphic contours in this set. It should be noted that: the PCB board may involve two situations. The first is that a small board is nested on a large board, and the second is that at least two PCB boards both contain component information or silk-screen character information. Then, it is necessary to make further judgments on these two situations in order to screen the closed graphic contours in the fourth set according to the two different situations. In an optional implementation manner, the dividing the two closed graphic contours in any set formed by combining the closed graphic contours in the fourth set into PCB closed graphic contours or other closed graphic contours according to the third overlapping area of the two closed graphic contours in this set includes: 361) For any two closed graphic contours in a combination formed by the closed graphic contours in the fourth set, if the third overlapping area of the two closed graphic contours in this set is equal to the area of one of the closed graphic contours in this set, then determine whether the two closed graphic contours in this set contain the same screening information; For two cases that the PCB may involve, perform collision calculations on all the closed graphic contours in the fourth set in pairs. If there is a collision, the collision area can be obtained based on the respective vector coordinates of the two closed graphic contours in this set. If the collision area is equal to the area of one of the closed graphic contours in this set. Exemplarily, for example, if the collision area is equal to the area of the closed graphic contour 04, then record the closed graphic contour 03 in this set and indicate that the closed graphic contour 03 contains the closed graphic contour 04. 362) If the collision area is equal to the area of one of the closed graphic contours in this set, then it is necessary to determine whether the two closed graphic contours in this set contain the same screening information. If the two closed graphic contours in this set contain the same screening information, then determine the closed graphic contour with a smaller area in this set as the PCB closed graphic contour, and the closed graphic contour with a larger area as the other closed graphic contour; if they do not contain the same screening information (i.e., a small board is nested on a large board), then confirm that the two closed graphic contours in this set are PCB closed graphic contours; 363) Store the PCB closed graphic contours in the sixth set, and iteratively update and store the other closed graphic contours in the fifth set; When there is the same screening information, then continue to determine the two closed graphic contours in this set. For example, whether the closed graphic contour 03 and the closed graphic contour 04 contain the same component information; if they do, then define the closed graphic contour 04 whose collision area is equal to the area of the closed graphic contour in this set as the PCB closed graphic contour, store it in the sixth set, define the other closed graphic contour in this set as the other closed graphic contour, and iteratively update and store it in the fifth set; otherwise, define the two closed graphic contours in this set as PCB closed graphic contours and store them in the sixth set. 364) Perform collision calculations on all the closed graphic contours in the fifth set and the closed graphic contours in the sixth set in pairs. If there is a collision, then confirm that the closed graphic contour belonging to the fifth set in this set continues to be the other closed graphic contour; if there is no collision, then determine whether the areas of the two closed graphic contours in this set are equal. If they are equal, then divide the closed graphic contour belonging to the fifth set in this set into PCB closed graphic contours, iteratively update and store them in the sixth set, and delete this closed graphic contour from the fifth set; if they are not equal, then continue to keep the closed graphic contour belonging to the fifth set in this set as the other closed graphic contour. When there is component information on at least one PCB board, since the fifth set stores other closed graphic contours and the sixth set stores PCB closed graphic contours. It is necessary to take one closed graphic contour from each of the fifth set and the sixth set and perform pairwise collision calculations. If there is a collision, the definition of the closed graphic contour belonging to the fifth set in this group remains unchanged, and the next group is judged; if there is no collision, it is judged whether the areas of the two closed graphic contours in this group are equal, that is, the area of the closed graphic contour can be obtained according to its respective vector coordinates. If the areas are equal, the closed graphic contour belonging to the fifth set in this group is defined as the PCB closed contour. That is, the closed graphic contour containing component information is used to screen out other PCB closed graphic contours with the same area and without component information, and iteratively update and store them in the sixth set, and delete them from the fifth set to update the fifth set; otherwise, the definition of the closed graphic contour belonging to the fifth set in this group remains unchanged; until all groups of package graphic contours are judged. S500, pairwise combine the PCB closed graphic contours and the other closed graphic contours to perform collision calculations to screen out the collision closed graphic contours from the other closed graphic contours; It should be noted that: the function of this step is to find out the closed graphic contours that collide with the PCB closed graphic contours and are not included in the other closed graphic contours, that is, the collision closed graphic contours. In this way, the precise range of the connecting ribs can be located by these collision closed graphic contours. In an optional implementation manner, the pairwise combination of the PCB closed graphic contours and the other closed graphic contours to perform collision calculations to screen out the collision closed graphic contours from the other closed graphic contours includes: 1) Pairwise combine the closed graphic contours in the fifth set and the closed graphic contours in the sixth set to perform collision calculations. If there is a collision, calculate the fourth overlapping area of the two closed graphic contours in this group; 2) For any group of two closed graphic contours formed by combining the closed graphic contours in the fifth set and the closed graphic contours in the sixth set, if the fourth overlapping area is 0, determine the closed graphic contour belonging to the fifth set in this group as the collision closed graphic contour and store it in the seventh set; 3) If there is no collision or the fourth overlapping area is greater than 0, confirm that the closed graphic contour belonging to the fifth set in this group continues to be the other closed graphic contour; 4) Delete the collision closed graphic contours from the fifth set and update the fifth set. Take one closed graphic contour from the fifth set and the sixth set respectively, and perform pairwise collision calculations. If there is a collision, calculate the collision area based on the vector coordinates of the two closed graphic contours in this group. If the collision area is equal to 0, define the closed graphic contour belonging to the fifth set in this group as the collision closed graphic contour, store it in the seventh set, and delete it from the fifth set to update the fifth set. Otherwise, the definition of the closed graphic contour belonging to the fifth set in this group remains unchanged. If there is no collision, the definition of the closed graphic contour belonging to the fifth set in this group remains unchanged. This process continues until all groups of encapsulated graphic contours have been judged. S600, select the collision closed graphic contour with the smallest area and determine it as the connecting rib. In an optional implementation, the selection of the collision closed graphic contour with the smallest area to determine as the connecting rib includes: 1) Calculate the area of the collision closed graphic contour according to the vector coordinates of the collision closed graphic contour. 2) Sort the areas of the collision closed graphic contours from largest to smallest, and select the collision closed graphic contour with the smallest area. 3) Determine the collision closed graphic contour with the smallest area as the connecting rib. The present invention can calculate the area of the closed graphic contours in the seventh set according to the vector coordinates of the closed graphic contours in the seventh set, sort the closed graphic contours in the seventh set according to the area size, and define the closed graphic contour with the smallest area in the seventh set as the connecting rib. The present invention provides a method for identifying connecting ribs in a PCB panel. By obtaining all the closed graphic contours on the same layer, performing pairwise collision calculations, determining the inclusion relationship between the two closed graphic contours in each group when there is a collision, and using the inclusion relationship to screen out the closed graphic contours that meet the inclusion relationship requirements from all the closed graphic contours; dividing all the closed graphic contours that meet the inclusion relationship requirements into PCB closed graphic contours or other closed graphic contours; performing pairwise collision calculations on the PCB closed graphic contours and the other closed graphic contours to screen out the collision closed graphic contours from the other closed graphic contours; selecting the collision closed graphic contour with the smallest area and determining it as the connecting rib. The present invention realizes the digital identification of connecting ribs according to the characteristics of connecting ribs in a PCB panel, which conforms to the digital trend of the industry. To facilitate the understanding of the embodiment solution of the present invention, a specific embodiment is given below for exemplary illustration. Step 1, read in the PCB design file. 1.1, Read in the PCB design file presented in CAD data, obtain all the closed graphic contours on the same layer from the PCB design file, and the vector coordinates of each closed graphic contour, and number all the closed graphic contours. As shown in Figure 3, and store them in Set 1. The numbers of the closed graphic contours in Set 1 are [001 - 046]; 1.2, According to the CAD data, obtain the component information D1: component reference number D1, component center coordinates (x, y), length L, and width W; Step 2, Combine all the closed graphic contours in Set 1 in pairs and perform collision calculations to obtain the collision and inclusion situations of the closed contours, as shown in Table 1 below: It can be concluded that the remaining closed graphic contours included in closed graphic contour 001 and closed graphic contour 005 are the same. The specific closed graphic contours are as follows: [002, 003, 004, 006, 007, 008, 009, 010, 011, 012, 013, 014, 015, 016, 017, 018, 019, 020, 021, 022, 023, 024, 025, 026, 027, 028, 029, 030, 031, 032, 033, 034, 035, 036, 037, 038, 039, 040, 041, 042, 043, 044, 044, 045, 046]. By the vector coordinates of closed graphic contour 001 and closed graphic contour 005, it is obtained that the area of closed graphic contour 001 is larger than the area of closed graphic contour 005.
