[0043] Furthermore, the encryption and decryption process of step S200 is as follows:

[0044] (1) For the remaining files other than the main file, each file can be optionally encrypted using a symmetric encryption algorithm, and the key and encryption type are written into the main file.

[0045] (2) The master file is encrypted using the public key issued by the system. At this time, only the system can decrypt the master file using the private key.

[0046] (3) When the standardized data file is uploaded to the system, the system uses zip to extract all files, decrypts the main file using the private key, reads the encryption type and key information of the remaining files from the main file, and uses this information to decrypt the other files.

[0047] Furthermore, if the master file contains key information, the master file is encrypted using an asymmetric encryption algorithm based on a public key.

[0048] Furthermore, in step S100, the method for obtaining the standardized data file includes generating the standardized data file directly from the test equipment or generating the standardized data file through the system by importing the data file into the system.

[0071] 1 to 6 , a method, device, and storage medium for data interaction based on standardized files include the following steps:

[0072] S100: Acquire a standardized data file, wherein the standardized data file is composed of a main file, a description file, and at least one data file in a compressed manner;

[0073] S200, decompressing the standardized data file to obtain the main file, the description file and at least one data file;

[0074] S300: Interpret the master file to obtain the application type, description file information, and data file information of the standardized data file, wherein the application type is a type of an application expected to be used to open the data file or a preset application name, the description file information includes description file encryption information, and the data file information includes data file encryption information;

[0075] S400, save the file, update the file server and update the database record;

[0076] S500, based on the read and write request of the front end, reading the application type, description file information and data file information of the standardized data file from the database or file server;

[0077] S600: Based on the front-end operation, update the application type, description file information and data file information;

[0078] S700, save the file, update the file server and update the database record;

[0079] S800: Generate a master file, description file, and data file from a database and a file server based on a file download request from the front end;

[0080] S900, encrypt the master file, description file and data file, compress the encrypted master file, description file and data file into a standardized data file, save the standardized data file, master file, description file and all data files to the file server and perform a download operation.

[0081] According to some embodiments of the present invention, the beneficial effects of the present invention are as follows:

[0082] The data interaction method, device and storage medium based on standardized files can define standard formats for different types of test files, design corresponding parsing programs for the original data generated by various devices, and then convert them into standard formats. The files in the standard format can be read, written and edited through a unified platform, making it convenient for staff to call test files and analyze and process the files.

[0083] Specifically, the method for obtaining the standardized data file includes generating the standardized data file directly from the test equipment or importing the data file into the system and generating the standardized data file through the system. The raw data file generated by the test equipment includes file formats such as wav, csv, xls, xlsx, and mosd.

[0084] 1 , in step S200 , the standardized data file is decompressed using a zip algorithm. The system extracts all files from the standardized data file by calling zip, including a main file, a description file, and at least one data file.

[0085] In some embodiments, other compression algorithms may also be used for compression and decompression.

[0086] Further, referring to FIG. 1 , the step S200 further includes:

[0087] S210: If the master file is an encrypted file, decrypt the master file using a preset private key;

[0088] Further, referring to FIG. 1 , the step S300 further includes:

[0089] S310: Determine whether the description file needs to be decrypted based on the description file encryption information; if the description file needs to be decrypted, decrypt the description file;

[0090] S320: Based on the data file encryption information, determine whether the data file needs to be decrypted; if the data file needs to be decrypted, decrypt the data file.

[0091] Further, referring to FIG. 2 , step S400 includes:

[0092] S410, saving the standardized data file, the master file, the description file and at least one of the data files to a file server;

[0093] S420: Update the records of the database, wherein the updating of the records of the database includes updating the application type of the standardized data file, the description file content, and the path of at least one of the data files.

[0094] Specifically, steps S100 to S420 are method steps for the system to receive standardized data files and process the received standardized data files. The purpose is to extract the information of the test data files or standardized data files of the test equipment and store the information in the database, and store the corresponding data files, description files and master files in the file server to facilitate users to call, modify, update and download the corresponding files.

[0095] Further, referring to FIG. 3 , step S700 includes:

[0096] S710, saving the standardized data file, the master file, the description file and at least one of the data files to a file server;

[0097] S720: Update the records of the database, wherein the updating of the records of the database includes updating the application type of the standardized data file, the description file content, and the path of at least one of the data files.

[0098] Further, referring to FIG. 4 , step S800 includes:

[0099] S810, read the application type, the file names of all data files, the file types, the file identifiers and the description file information from the database;

[0100] S820. Regenerate the master file and description file and save them to the file server.

[0101] It should be noted that in step S800, there is a possibility that the file will be modified by a third party after the previous standardized data file is generated and before the file download request occurs. Therefore, after receiving the download request, in order to avoid possible data changes in the database caused by other programs, the latest file needs to be regenerated.

[0102] Further, referring to FIG. 5 , step S900 includes:

[0103] S910, encrypting description files and data files;

[0104] S920, after updating the encryption information to the master file, encrypt the master file;

[0105] S930. Compress the master file, description file, and all data files using zip compression to obtain a standardized data file, and save the standardized data file, master file, description file, and all data files to a file server;

[0106] S940: Execute a download operation to download the corresponding file in the file server to the front end.

[0107] Specifically, steps S500 to S930 are the execution steps of the system corresponding to the front-end read and write requests and file download requests, the purpose of which is to provide users with a platform for reading, writing and editing data files, and to provide a download function for the latest data files.

[0108] 6 , the present invention further proposes a device for interactive measurement and control data based on standardized files, for implementing a data interaction method based on standardized files, characterized in that the device comprises:

[0109] File server, used to store files;

[0110] Database, used to store file information;

[0111] The processing device is used to generate and process the description file, the master file and the standardized data file. The file server and the database are respectively connected to the processing device.

[0112] Specifically, the front end can be a user application, which includes host computer software, mobile phone APP and web pages. The front end uploads, requests data and downloads data by connecting to the processing device. The processing device updates information in real time and provides external reading, writing, editing, uploading and downloading services through the connection with the database and the file server.

[0113] The present invention further provides a computer-readable storage medium having program instructions stored thereon. When the program instructions are executed by a processor, a data interaction method based on a standardized file is implemented.

[0114] In addition, referring to FIG7 to FIG11 , if only one or more data files can be obtained from the test equipment, in order to integrate the one or more data files into a standardized data file, an embodiment of the present invention further provides a standardized data file generation method, apparatus, and storage medium. Referring to FIG7 , the method includes the following steps:

[0115] S100, obtaining at least one data file, extracting file information of each data file, and assigning an identifier to each data file;

[0116] S200, creating a description file, and writing the interpretation mode, mutual relationship and application status of the data file into the description file based on a data structure predefined by the application that expects to open the data file;

[0117] S300, creating a master file, wherein the master file includes a data file information segment and a description file information segment;

[0118] S400: Create a standardized data file, write the type of application that is expected to open the standardized data file into the application type information segment of the master file, and package the master file, description file, and data file into the standardized data file;

[0119] S500: Compress the standardized data file to obtain a compressed file, and modify the extension of the compressed file.

[0120] Specifically, for step S100, obtaining at least one data file includes obtaining the data file from the test device, or obtaining the file by downloading from a specific file system or file server.

[0121] According to some embodiments of the present invention, the beneficial effects of the present invention are as follows:

[0122] The standardized data file generation method, device and storage medium can define a standard format for different types of test files, design corresponding parsing programs for the original data generated by various devices, and then convert them into a standard format.

[0123] Further, referring to FIG. 7 to FIG. 10 , the file information of the data file includes a file name and a file type.

[0124] Further, referring to FIG. 7 to FIG. 10 , the format of the data file is csv format, and the format of the description file includes json format, xml format, or yml format.

[0125] 7 to 10 , after step S200, the method further includes encrypting the data file and the description file using a symmetric encryption algorithm. In some embodiments, after encrypting the data file and the description file using the symmetric encryption algorithm, information such as the file name, file type, decryption type, and key of the description file is written into the master file.

[0126] Further, referring to Figures 7 to 10, after step S300, the file information, identifiers and data file encryption information of all data files are written into the data file information segment of the master file, and the file name, type and description file encryption information of the description file are written into the description file information segment.

[0127] 7 to 10, if the master file contains key information, the master file is encrypted using an asymmetric encryption algorithm based on a public key. In some embodiments, when the master file contains key information, the master file is encrypted using a public key.

[0128] 7 to 10, the standardized data files are compressed based on the zip algorithm. In some embodiments, all data files, description files, and main files are compressed into one file using zip, and the format of the compressed file is mdf.

[0129] In some embodiments, to ensure file security, the files in the standardized data file (mdf file) are optionally encrypted. The encryption and decryption process is as follows:

[0130] (1) For the remaining files other than the main file, each file can be optionally encrypted using a symmetric encryption algorithm, and the key and encryption type are written into the main file.

[0131] (2) The master file is encrypted using the public key issued by the system. At this time, only the system can decrypt the master file using the private key.

[0132] (3) When the standardized data file (mdf file) is uploaded to the system, the system uses zip to extract all files, decrypts the main file using the private key, reads the encryption type and key information of the remaining files from the main file, and uses this information to decrypt the other files.

[0133] In addition, symmetric encryption algorithms run very fast, while asymmetric encryption algorithms are slower, but have the advantage of providing public keys to users. Combining the two here can provide very flexible security protection.

[0134] Further, referring to FIG. 7 to FIG. 10 , the step S500 further includes: modifying the extension of the compressed file to mdf.

[0135] Specifically, in a specific embodiment, when the generated standardized data file MDF is not encrypted, the specific method flow is as follows:

[0136] (1) Collect three data files, namely A.csv, B.csv, and C.csv, and assign identifiers A, B, and C to them respectively.

[0137] (2) Create a new description file and name it Desc. Write the parsing methods and relationships of the three files A, B, and C into the description file (Desc file) according to the data structure predefined by the application.

[0138] (3) Write name=A.csv, id=A, type=csv into the data file information section of the master file;

[0139] Write name=B.csv, id=B, type=csv into the data file information section of the main file;

[0140] Write name=C.csv, id=C, type=csv into the data file information segment of the main file.

[0141] (4) Write name=Desc, type=json into the description file information segment of the main file.

[0142] (5) Write the application type type = TYPE_ENTHALPY_DIFFERENCE_LAB into the application type information segment of the main file.

[0143] (6) Compress all the above files using zip to obtain a compressed file, and set the extension of the compressed file to mdf.

[0144] Specifically, in a specific embodiment, when the generated standardized data file MDF is encrypted, the specific method flow is as follows:

[0145] (1) Three data files are collected, namely A.csv, B.csv, and C.csv, and the identifiers are assigned to them as A, B, and C respectively.

[0146] (2) Create a new description file and name it Desc. Write the parsing methods and relationships of the three files A, B, and C into the description file (Desc file) according to the data structure predefined by the application.

[0147] (3) Use a symmetric encryption algorithm and a custom key to encrypt three data files and one description file.

[0148] (4) Write name=A.csv, id=A, type=csv, crypt=aes256, and passwd=“key string” into the data file information section of the master file;

[0149] Write name = B.csv, id = B, type = csv, crypt = aes256, and passwd = "key string" into the data file information section of the main file;

[0150] Write name=C.csv, id=C, type=csv, crypt=aes256, and passwd=“key string” into the data file information segment of the main file.

[0151] (5) Write name=Desc, type=json, crypt=aes256 and passwd=“key string” into the description file information segment of the main file.

[0152] (6) Write the application type type = TYPE_ENTHALPY_DIFFERENCE_LAB into the application type information segment in the boot file.

[0153] (7) Use the issued public key to asymmetrically encrypt the master file.

[0154] (8) Compress all the above files using zip to obtain a compressed file, and set the extension of the compressed file to mdf.

[0155] In some embodiments, referring to FIG. 2 to FIG. 4 , the standardized data file (mdf file) includes a master file, a description file, and at least one data file (data file 1, data file 2, ..., data file n), wherein:

[0156] The main file includes: version number, application type,

[0157] Describes the file's name, type, encryption type, and key.

[0158] The file name, type, identifier, encryption type and key of data file 1,

[0159] The file name, type, identifier, encryption type and key of data file 2,

[0160] …

[0161] The file name, type, identifier, encryption type, and key of the data file n;

[0162] The description file includes: the relationship between data file 1, data file 2 ... data file n and the interpretation method, and the call data of the application status;

[0163] The standardized data file (mdf file) also includes at least one data file: data file 1, data file 2, ..., data file n.

[0164] Specifically, the standardized data file (MDF file) is a safe and controllable file format for combining multiple files. The standardized data file (MDF file) is formed by compressing multiple files into one file using zip and defining the file extension as mdf. The standardized data file (MDF file) consists of three files: a data file, a description file, and a main file.

[0165] Among them, the data file is one or more data files obtained by collecting or exporting data from the test equipment, and the multiple data files are named with different names. A different string is assigned to each data file as a unique identifier. The identifier uniquely identifies a data file in the description file, and the content of the data file can optionally be encrypted by a symmetric encryption algorithm.

[0166] The description file has no predefined file name and needs to be customized and named differently from other files. The description file records the following content based on the predefined application data structure: the relationship between each data file, the method of parsing each data file, and the status of the standardized data file (mdf file) application. The description file content can optionally be encrypted using a symmetric encryption algorithm.

[0167] The file name of the master file is uniformly defined as "app" and the master file has no file name extension. The master file records the following contents based on the predefined master file data structure: the application type of the standardized data file (mdf file), the name, type, and encryption information of the description file, and the name, type, identifier, and encryption information of all data files. If the master file content contains key information, the master file is encrypted using an asymmetric algorithm using the public key.

[0168] In particular, the standardized data file (mdf file) also includes an error tolerance method and other encryption methods except the zip encryption method.

[0169] The standardized data file (mdf file) also includes setting a compression password when using zip compression.

[0170] In some embodiments, the master file can be expanded to record more information, including but not limited to:
