Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanying figures are described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Referring to fig. 1, a method for checking consistency between a virtual prototype car and part numbers in a loading list according to this embodiment includes:
processing all part information in the loading list into part numbers in a standard format and then storing the part numbers in a first standard part number list;
extracting part numbers in a standard format from all the part information in the virtual sample car and storing the part numbers in a second standard part number list;
and establishing a cyclic check model, performing consistency check on the part numbers of the first standard part number list and the second standard part number list, and marking each part number with corresponding consistency according to a check result.
The consistency of the part numbers in the virtual sample vehicle and the loading list is automatically checked, the checking efficiency is effectively improved, meanwhile, according to consistency marks made on each part number, the difference between the virtual sample vehicle and the loading list is found in time to solve, the virtual sample vehicle is completely realized according to the loading list, effective tracking and checking on the loading list are realized, and smooth proceeding of subsequent actual loading is guaranteed through the loading effect of the virtual sample vehicle.
The part numbers in the first standard part number list and the part numbers in the second standard part number list adopt the same standard format, and in the specific implementation process, the format of the part numbers in the part information of the assembly supply level in the virtual sample vehicle can be used as the standard format, so that all the part information in the vehicle list only needs to be processed into the part numbers of the standard format, the workload is greatly reduced, meanwhile, the part numbers in the first standard part number list and the part numbers in the second standard part number list adopt the same standard format, the convenience is provided for the subsequent consistency check work, and the reliability of the check result is ensured.
In addition, the first standard part number list and the second standard part number list can be stored in an Excel file format, so that related processing operations can be conveniently carried out by using plug-ins of Excel, the method is simple and clear, cloud storage can be carried out, subsequent consistency verification work can be conveniently carried out by using a cloud computing processing mode, and the verification efficiency is further improved.
In the method for checking consistency between the virtual sample car and the part numbers in the loading list provided by this embodiment, the method for processing all the part information in the loading list into the part numbers in the standard format specifically includes:
extracting all part information in a loading list;
deleting the color data of all the part information according to the naming rule of the part information to obtain a part number;
and converting the interval format between the data bits of the part number into a standard interval format to obtain the part number in the standard format.
The part number format standardization of the loading list is carried out, and the aim is to carry out the format standardization on the part number of each ordered part in the loading list so as to provide a reliable data source for the subsequent consistency check work. When a loading list is appointed, as some parts need color information, a plurality of data bits corresponding to the color data in the part information need to be deleted according to the naming rule of the part information, and part numbers are obtained. Moreover, different modules of the loading list can be completed by different engineer teams, so that the interval formats among the data bits of the part numbers in the loading list are inconsistent, for example, multiple interval formats for spacing the data bits by adopting space symbols such as spaces, underlines or dot symbols need to be uniformly converted into standard interval formats, a reliable checked data source is provided for subsequent consistency checking work, misjudgment caused by format inconsistency is avoided, and the efficiency of the consistency checking work of the virtual prototype car and the part numbers in the loading list is improved.
In the method for checking consistency between a virtual sample vehicle and part numbers in a loading list provided in this embodiment, the method for extracting part numbers in a standard format from all part information of the virtual sample vehicle specifically includes:
exporting a structure tree file of the virtual sample car from the Deltagen software;
screening part information of an assembly supply level in the structural tree file;
and extracting the part number in the standard format from the part information according to the naming rule of the part information.
In specific implementation, the structure tree file in the plmxml format can be exported through an export function in the Deltagen software, and the structure tree file can be opened and edited through Excel.
Further, the method for screening the part information of the assembly supply level in the structure tree file comprises the following steps:
analyzing a data structure of the reading structure tree file, and deleting redundant information in the structure tree file;
traversing all the part information in the structure tree file, and simultaneously judging and deleting all the child node part information in the assembly part information according to the identifier of the assembly part to obtain the part information of the assembly supply level.
In the method for screening the part information at the assembly supply level in the structure tree file, redundant information in the structure tree file is user-defined input information, a user can input the information in a customized manner in the Deltagen software, the information can be various text contents and part numbers, and the information needs to be deleted in order to avoid influencing the subsequent part number processing. The simplest method for deleting redundant information is as follows: according to the identifier of user-defined input information, such as 'UserData', a search model is built through the search function of Excel software or by self to traverse the exported structure tree file in the plmxml format, and all the line data with the identifier of 'UserData' are deleted. Furthermore, the assembly supply part information in the Deltagen software is often composed of data of a plurality of parts, and we need to extract part numbers only at the assembly supply level, and for such cases, all sub-node part information in the assembly part information is judged and deleted according to identifiers of assembly parts, so as to obtain the part information at the assembly supply level. For example: an identifier 'ZSB' is defined in the Deltagen software as an identifier of the assembly part, and when the identifier of the assembly part is detected, all child nodes under the node of the assembly part are traversed according to the data relation in the structure tree file and deletion operation is carried out.
After screening out the part information of the assembly supply level in the structure tree file, the method for extracting the part number in the standard format from the part information comprises the following steps: because the part number in the part information of the assembly supply level is default to be set to be in a standard format, the format is not required to be modified; only the part information of the assembly supply level needs to be traversed, and meanwhile, the data segment corresponding to the part number in the part information of the assembly supply level is extracted according to the naming rule of the part information of the assembly supply level. For example, only part number information of all supply levels is left in the structure tree file, according to the naming rule of the part information in the Deltagen software, all line data containing the part number are screened out firstly, and then the part number is further extracted from the line data.
Referring to fig. 2 or fig. 3, in the method for checking consistency of part numbers in a virtual prototype vehicle and a loading list provided in this embodiment, the method for checking consistency of part numbers in a first standard part number list and part numbers in a second standard part number list specifically includes:
checking whether the part numbers in the first standard part number list exist in the second standard part number list one by one, and marking the checking result corresponding to the part numbers in the first standard part number list;
and checking whether the part numbers in the second standard part number list exist in the first standard part number list one by one, and correspondingly marking the checking result on the part numbers in the second standard part number list.
The verification process can be realized by adopting a vlookup function in Excel software, but the operation is very complicated, some columns need to be added again, the time is consumed, and the searching precision cannot be completely ensured.
In this embodiment, the consistency check is preferably implemented by establishing a cyclic check model, and referring to fig. 2, a first row of part numbers in a first standard part number list is extracted, then a first row of part numbers in a second standard part number list is extracted, whether two part numbers are consistent or not is judged, and if so, a row identification bit corresponding to the part number in the first standard part number list is set to be 1; if the two parts are not consistent, further judging whether the second standard part number list reaches the last line, and if the second standard part number list reaches the last line, setting a line identification bit corresponding to the part number of the first standard part number list to be 0; and if the second standard part number list does not reach the last line, extracting the part numbers of the next line of the second standard part number list, and continuously judging whether the two part numbers are consistent or not until the second standard part number list reaches the last line. And after the row identification bit corresponding to the part number in the first standard part number list is set to be 1 or 0, judging whether the first standard part number list reaches the last row, if so, stopping checking, and if not, extracting the part number in the next row of the first standard part number list to carry out the checking operation until the last row of the first standard part number list is finished. The specific process that the cyclic verification model realizes the one-by-one verification of whether the part numbers in the first standard part number list exist in the second standard part number list and correspondingly marks the verification result on the part numbers in the first standard part number list is realized.
Referring to fig. 3 again, first, the first line of part numbers in the second standard part number list is extracted, then the first line of part numbers in the first standard part number list is extracted, whether the two part numbers are consistent or not is judged, and if so, the line identification bit corresponding to the part number in the second standard part number list is set to be 1; if the first standard part number list is inconsistent with the second standard part number list, further judging whether the first standard part number list reaches the last line, and if the first standard part number list reaches the last line, setting a line identification bit corresponding to the part number of the second standard part number list to be 0; and if the first standard part number list does not reach the last line, extracting the part numbers of the next line of the first standard part number list, and continuously judging whether the two part numbers are consistent or not until the first standard part number list reaches the last line. And after the line identification bit corresponding to the part number in the second standard part number list is set to be 1 or 0, judging whether the second standard part number list reaches the last line, if so, stopping checking, and if not, extracting the part number in the next line of the second standard part number list to carry out the checking operation until the last line of the second standard part number list is finished. The specific process that the cyclic verification model realizes the one-by-one verification of whether the part numbers in the second standard part number list exist in the first standard part number list and correspondingly marks the verification result on the part numbers in the second standard part number list is realized.
The two processes can be carried out synchronously to improve the checking efficiency, and the problems of low efficiency, long time consumption, easy error and the like existing when the consistency of the part numbers in the virtual sample car and the loading list is checked by manual contrast are solved.
