[0047] Embodiment 1

[0048] Refer to Figure 1 , Figure 1 which is a schematic flowchart of a tag-based file management method provided in Embodiment 1 of the present invention. This method can be applied to an electronic device, which includes a processor, a communication interface, a memory, and a communication bus. Among them, the processor, the communication interface, and the memory communicate with each other through the communication bus, and the present invention does not make specific limitations thereto. Specifically, refer to Figure 1 , and this method includes the following steps S101-S108.

[0049] S101, If a data file to be stored is received, obtain the check code of the data file.

[0050] The data file to be stored contains the input signal waveform of the on-board equipment of locomotive signals during operation in the track circuit. All data files can be stored in one or more folders of the computer system. The checksum is used to check whether there are data files with the same content in the folder. For any data files with different contents, their checksums are different.

[0051] In one embodiment, obtaining the checksum of the data file includes: using the checksum function Simulink.getFileChecksum to calculate the MD5 checksum of the data file.

[0052] S102, determine whether there is a target file named after the checksum in the preset folder.

[0053] The target file is a data file obtained according to user needs. The calculated checksum is used to name the data file. According to the fact that for any data files with different contents, their checksums are different, it is possible to check whether there are duplicate data files in the folder through the MD5 checksum.

[0054] In one embodiment, when a data file to be stored is newly added to the folder, the effect of deduplication is achieved by determining whether there is a target file named after the checksum in the folder.

[0055] If there is a target file named after the checksum, it means that there are data files with the same content in the folder, and there is no need to newly add the data file to be stored to this folder.

[0056] S103, if there is no target file named after the checksum in the folder, receive the label set by the user for the data file and store the label in the structure.

[0057] The label set by the user for the data file can be a binary label, and the value of the label is true or false. It can also be an enumerated label, and the value of the label is a few limited values, such as Monday to Sunday. It can also be a numerical label, and the value of the label is a large set or continuous numerical values, such as duration, date, string, etc. A structure is a new data type composed of a batch of data. It can define a data type or contain multiple data types.

[0058] In one embodiment, the above step S103 includes the following steps: S301 - S302.

[0059] S301, use the WenJG_jsonGen function to set the label to obtain the label value.

[0060] The WenJG_jsonGen function can obtain the tag value by setting according to the tags set by the user, and the tag value can be of multiple data types.

[0061] S302, store the tag value of the said tag into the MATLAB structure.

[0062] Define a MATLAB structure according to the data type of the tag value of the said tag for storing the tag value of this data type. The structure can be a data type or composed of multiple data types. At the same time, the structure can also be a set of some elements. The structure can be declared as a variable, pointer or array, etc. to implement a more complex data structure.

[0063] S104, convert the said structure into an information file, and the format of the information file is JSON format.

[0064] JSON is a lightweight data exchange format, easy to read and write, and can effectively improve data efficiency. Converting the structure into an information file in JSON format is to utilize the high-efficiency transmission of the JSON format file during conversion and reading to improve operation efficiency.

[0065] In one embodiment, according to the structure obtained in step S103, use the Jsonencode function to convert the said structure into an information file in JSON format, and convert the MATLAB structure into an information file in JSON format to complete the format conversion.

[0066] S105, store the said data file and information file into the said folder, and the names of the data file and the information file are the said check code.

[0067] The information file contains the tags set by the user, and the check code calculated by the data file is used as the file name of the corresponding information file. The difference between the data file and the information file is that the extension of the information file is.JSON.

[0068] In one embodiment, use the MD5 check code obtained in step S101 as the file names of the said data file and the information file. According to the uniqueness of the MD5 code, make the data file and the information file correspond one by one to improve the accuracy rate during data storage.

[0069] S106, if a data extraction request is received, the data extraction request includes the target tag.

[0070] The target tag can be a tag selected by the user according to needs. After the format conversion between the structure and the information file, the target tag is stored in the information file. The data extraction request also includes a target information file and a target data file. The target tag corresponds to the target information file and the target data file. The user can retrieve the corresponding information file and data file only through the target tag, which is convenient, fast, and easy to operate.

[0071] In one embodiment, a data extraction request is generated according to the information file required by the user. The data request contains a target tag, which is used to match the corresponding information file.

[0072] S107, Retrieve the target information file from the folder according to the target tag.

[0073] The target information file is uniformly in JSON format. When the structure is converted into an information file, the tags existing in the structure also exist in the information file. Therefore, the target information file contains the target tag. The target tag corresponds to the target information file, and the target information file can be obtained through the matching of the target tag.

[0074] In one embodiment, according to the target tag, use the WenJG_jsonToExcel_objs function to find the target information file and return the storage path of the target information file. The WenJG_jsonToExcel_objs function has an analysis and modeling function, which can sort out the characteristics of each tag and the relationship between the tag and the information file. The user can use this function to obtain an image and hierarchical data summary when browsing the data file and quickly find the required data file type.

[0075] S108, Retrieve the target data file from the folder according to the name of the target information file.

[0076] Due to the efficient transmission characteristics of the JSON format information file, the user can quickly retrieve the required information file according to the target tag. Each information file corresponds to a data file (this connection is generated by the MD5 checksum).

[0077] In one embodiment, it can be obtained from step S105 that the MD5 checksum is used as the file name of the data file and the information file. Through the file name of the target information file, the corresponding target data file is found.

[0078] Specifically, by using the MD5 checksum of the data file to determine whether there are duplicate data files, the effect of quickly removing duplicates is achieved. By converting the MATLAB structure into an information file in JSON format, the data transmission efficiency and conversion speed are improved, facilitating calls. By storing the tags in the MATLAB structure, the required information files can be retrieved according to the tags, and the required data files can be retrieved according to the information files. Due to the high transmission efficiency of the JSON format, the required information files and data files can be quickly retrieved according to the tags, improving the efficiency of data extraction.

[0079] Embodiment 2

[0080] See Figure 2 , Figure 2 which is a schematic flowchart of a tag-based file management method provided in Embodiment 2 of the present invention. The tag-based file management method of Embodiment 2 includes steps S201-S208, where steps S201-S208 are similar to steps S101-S108 in the above Embodiment 1 and will not be elaborated here. The additional steps S209-S214 in this embodiment will be described in detail below.

[0081] S209, receiving an information file tag modification request, where the information file tag modification request includes the tag to be modified.

[0082] The tag to be modified may be a tag set incorrectly by the user when storing the data file, and this incorrectly set tag has been converted to the information file through formatting; the tag to be modified may also be a tag reset by the user according to needs.

[0083] In one embodiment, receiving an information file tag modification request, where the information file tag modification request includes the tag to be modified selected by the user, and a modification request for any tag in the information file can be received.

[0084] S210, according to the tag to be modified, using the WenJG_jsonToExcel_objs function to retrieve the information file to be modified from the folder.

[0085] The WenJG_jsonToExcel_objs function outputs the obtained JSON to an Excel cell, that is, exports the output of the JSON to an Excel cell, so that the information file corresponding to the tag can be seen more intuitively, and then the storage location of the JSON file can be obtained.

[0086] In one embodiment, according to the tag to be modified, using the WenJG_jsonToExcel_objs function to find the information file to be modified and return the storage path of the information file to be modified.

[0087] S211. Use the Jsondecode function to convert the information file to be modified into a structure to be modified.

[0088] The structure to be modified stores the tags to be modified. When the information file to be modified is stored in the folder, the Jsonencode function has already converted the structure into a JSON-format information file. Due to the good readability of the structure, the information file to be modified is thus converted into a structure with good readability, facilitating reading and modification.

[0089] In one embodiment, the Jsondecode function is used to complete the format conversion between the MATLAB structure and the JSON-format information file. The JSON-format information file is converted into a MATLAB structure through the Jsondecode function, where the MATLAB structure has good readability and is convenient for reading.

[0090] S212. Use the WenJG_jsonFieldSetOld.m function to modify the tags to be modified in the structure to be modified.

[0091] The WenJG_jsonFieldSetOld.m function can read the data in the structure and has the function of resetting the bit fields in the structure. The bit fields of the structure are essentially a data type. By resetting the bit fields of the structure, that is, redefining the data type in the structure. The tags to be modified are also a data type. Resetting the bit fields thus modifies the tags in the structure, and the range of modification of the tags can be adding, deleting, renaming, and modifying values.

[0092] In one embodiment, the tags in the MATLAB structure are read through the WenJG_jsonFieldSetOld.m function and the tags in the MATLAB structure are modified.

[0093] S213. Use the Jsonencode function to convert the modified structure into a JSON-format information file.

[0094] The modified structure needs to be converted into a JSON-format information file and stored back in the folder before it can be called and read. By converting it back into a JSON-format information file, the file format is unified, the modification difficulty is reduced, and the file management efficiency is improved.

[0095] In one embodiment, after the labels in the MATLAB structure are modified, the modified MATLAB structure needs to be formatted again. Use the Jsonencode function to convert the modified MATLAB structure into a JSON format information file and store it back in the folder to complete the label modification process.

[0096] S214. Use the w_strTypeIsSame function to determine whether the structure is legal. The legality means that any sub-domain in the structure and any sub-domain in the standard structure are subsets of each other.

[0097] If it is legal, execute step S204 to convert the structure into an information file, and the format of the information file is JSON format.

[0098] See Figure 3 In one embodiment, step S214 includes:

[0099] S2141. Input parameters str1 and str2.

[0100] Use the w_strTypeIsSame function to input parameters str1 and parameter str2. The parameter str1 and parameter str2 correspond to the structure to be verified and the standard structure respectively. The w_strTypeIsSame function is applicable to the type comparison of MATLAB structures and is used to convert numeric variables or constants into character variables or constants. In this embodiment, through the structure to be verified corresponding to parameter str1 and the standard structure corresponding to parameter str2, a constant result is obtained through the w_strTypeIsSame function, and this constant is used to indicate whether the structure is legal. The legality means that the structure can be used for format conversion with the information file.

[0101] S2142. Determine whether both parameter str1 and parameter str2 are structures.

[0102] The main purpose of determining whether both parameter str1 and parameter str2 are structures is to determine whether parameter str1 is a structure. If parameter str1 is not a structure, then parameter str1 is not readable.

[0103] If parameter str1 is not a structure, determine that the structure is illegal.

[0104] S2143. If both parameter str1 and parameter str2 are structures, obtain the sub-domain field1 of parameter str1 and the sub-domain field2 of parameter str2.

[0105] The purpose of obtaining the subfield field1 of parameter str1 and the subfield field2 of parameter str2 is to pass the subfields as parameters so that the subfield field1 of str1 and the subfield field2 of parameter str2 can be used as parameters for the next step.

[0106] S2144, determine whether the subfield field1 and the subfield field2 are subsets of each other.

[0107] If the subfield field1 and the subfield field2 are subsets of each other, it proves that field1 is a necessary and sufficient condition for field2, that is, the subfield field1 is equal to field2, which can prove that a certain part of parameter str1 is the same as a certain part of parameter str2.

[0108] If the subfield field1 and the subfield field2 are not subsets of each other, determine that the structure is illegal.

[0109] S2145, if the subfield fields1 and the subfield fields2 are subsets of each other, traverse all subfields of parameter str1 and parameter str2.

[0110] By traversing all subfields of parameter str1 and parameter str2, it is possible to determine whether parameter str1 and parameter str2 are of the same type of structure.

[0111] S2146, determine whether the traversal is completed.

[0112] By determining whether the traversal is completed, the result of whether parameter str1 and str2 are of the same type of structure can be obtained.

[0113] S2147, if the traversal is completed, determine that the structure is legal.

[0114] The completion of the traversal means that all subfields in parameter str1 and parameter str2 are subsets of each other, which can prove that parameter str1 and str2 are of the same type of structure.

[0115] S2148, if the traversal is not completed, input the field values of all subfields of parameter str1 and the field values of all subfields of parameter str2 respectively through a recursive algorithm;

[0116] Through the recursive algorithm, input the subfield values fieldn in parameter str1 and parameter str2. The purpose is to make the field value of parameter str1 and the field value of parameter str2 be subsets of each other, and through recursion, make all field values of parameter str1 and all field values of parameter str2 be subsets of each other.

[0117] S2149, Determine whether the recursion is completed. If the recursion is completed, determine that the structure is legal.

[0118] S2150, If the recursion is not completed, then determine that the structure is illegal.

[0119] If the recursion is completed, it proves that all sub-domains in parameter str1 and parameter str2 are subsets of each other, that is, it can prove that parameter str1 and str2 are structures of the same type; if the recursion is not completed, it proves that parameter str1 and parameter str2 are not exactly the same in structure and are not of the same type as the standard structure, and the verification result is illegal.

[0120] Specifically, the structures in the folder need to be compared with the standard structure. By verifying the legality of the structure, the format conversion between the MATLAB structure and the information file can be performed only after the structure is verified to be legal, which ensures the integrity of the data during transmission and encryption, prevents data omission or loss, and reduces the error of data transmission.

[0121] The format conversion between the structure and the information file is completed by using the Jsonencode function and the Jsondecode function. According to the high efficiency of the information file in JSON format and the good readability of the MATLAB structure, the labels in the MATLAB structure can be modified, and then the modified MATLAB structure is converted into an information file in JSON format by using the Jsonencode function. The labels corresponding to the information file can be modified according to actual needs. By modifying the labels in the information file, due to the unity of the JSON format, the modification difficulty is reduced, and thus the efficiency of file management is improved. The required information file can be retrieved according to the label, and the data file corresponding to the information file can be retrieved through the naming method of the MD5 code (one data file corresponds to only one information file, and the file name is the MD5 code calculated according to the data file). Due to the high-efficiency transmission of the information file in JSON format, the required information file and data file can be quickly retrieved according to the label, improving the efficiency of data extraction.
