[0001] The present application relates to the field of data processing, and in particular, to a file management method, device, electronic device, storage medium and computer program product. Background Art

[0002] With the development of automatic control systems, the product characteristics, implementation principles, and configuration and maintenance methods of PLCs (Programmable Logic Controllers) produced by various manufacturers of automatic control systems are different. After customers purchase PLCs from different manufacturers, they need to set up a corresponding configuration tool to configure and maintain the PLCs of different manufacturers through the corresponding configuration tool. However, with the upgrade of products and changes in demand, the types of PLCs deployed in automatic control systems have increased. When it is necessary to frequently configure and maintain each PLC, not only can the configuration export switch not be realized quickly, but the management efficiency of the automatic control system is also reduced. Summary of the invention

[0003] In view of this, the purpose of the present application is to provide a file management method, device, electronic device, storage medium and computer program product to improve the problem of low management efficiency of the automation control system.

[0004] The embodiment of the present application is implemented as follows:

[0005] In a first aspect, an embodiment of the present application provides a file management method, including: obtaining a first configuration file of a target PLC; parsing the first configuration file according to a first structure corresponding to the manufacturer to which the target PLC belongs to obtain relevant information of the first configuration file; saving the relevant information according to a preset second structure, wherein the saved relevant information is editable information; upon completing the editing of the saved relevant information, translating the edited relevant information into a second configuration file according to the first structure.

[0006] In the embodiment of the present application, there is no need to deploy corresponding configuration tools for different manufacturers. After obtaining the configuration files of PLCs of different manufacturers, the configuration files are first parsed according to the first structure corresponding to the manufacturer to which the target PLC belongs, and then saved uniformly according to the second structure to achieve unified management of the relevant information of the configuration files. After completing the editing of the relevant information, the relevant information is translated into the configuration file according to the first structure. In this way, while managing the configuration files of PLCs of different manufacturers, they can also be parsed and translated separately according to the differences in the structures of the configuration files corresponding to different manufacturers, thereby improving the management efficiency of the automation control system.

[0007] In an optional implementation, the first configuration file is parsed according to a first structure corresponding to the manufacturer to which the target PLC belongs to obtain relevant information of the first configuration file, including: obtaining PLC manufacturer information and / or CPU model information contained in the first configuration file; determining the manufacturer to which the target PLC belongs based on the PLC manufacturer information and / or the CPU model information; obtaining a first structure corresponding to the manufacturer from a preset database, the preset database containing structures of various manufacturers including the manufacturer; parsing the first configuration file according to the first structure to obtain relevant information of the first configuration file.

[0008] In an embodiment of the present application, the manufacturer of the target PLC is determined based on the PLC manufacturer information and / or CPU model information contained in the first configuration file, so as to obtain the first structure corresponding to the manufacturer of the target PLC in the database, and the first configuration file of the target PLC produced by the manufacturer is parsed based on the first structure, so as to achieve management of configuration files of PLCs from different manufacturers while also being able to perform separate parsing based on the differences in structures between configuration files corresponding to different manufacturers, thereby improving the management efficiency of the automation control system.

[0009] In an optional implementation, the saving of the relevant information according to a preset second structure includes: converting the format of the relevant information according to the second structure; and saving the relevant information in the converted format to a corresponding interface.

[0010] In an embodiment of the present application, the relevant information is converted into the format of the second structure and saved to the corresponding interface, so that the relevant information can be processed in the data format of the second structure by calling the interface later, thereby achieving unified processing of configurations of different manufacturers.

[0011] In an optional embodiment, after the relevant information is saved according to a preset second structure, the method further includes: upon receiving a processing request sent by a user, calling the interface to map the relevant information in the converted format to a preset display interface, and the processing request is a request to process the relevant information in the converted format.

[0012] In an embodiment of the present application, relevant information may be mapped to a display interface so that the relevant information can be processed through the display interface to achieve secure management and control of the PLC configuration file.

[0014] In the embodiment of the present application, corresponding management policies can be assigned to configuration files of different manufacturers, and different users can be authorized so that each user has the authority to process different related information. When a user requests to process certain related information, the user's authority is checked to determine whether the user is allowed to process the related information, so as to improve the security of the information.

[0015] In an optional embodiment, the method further includes: when the user does not have the authority to process the relevant information in the converted format, sending an authorization notification corresponding to the user to a preset management end, so that the management end grants the user the authority to process the relevant information in the converted format based on the authorization notification.

[0016] In the embodiment of the present application, the management end performs authorization operations on the user, and the management end authorizes the user to ensure that only authorized users can display and process relevant information, thereby preventing illegal users from operating the information, thereby improving the security of the information.

[0017] In an optional embodiment, after translating the edited relevant information into a second configuration file according to the first structure, it also includes: based on a preset communication protocol, detecting whether the communication with the target PLC is in a normal state; if the communication with the target PLC is in a normal state, downloading the second configuration file to the target PLC.

[0018] In an embodiment of the present application, a communication protocol is used to detect whether the communication state with the target PLC is normal, so as to avoid data loss caused by file transfer in an abnormal communication state, thereby improving the security of information.

[0034] In the description of the embodiments of the present application, unless otherwise clearly specified or limited, the technical term "connection" may refer to a direct connection or an indirect connection through an intermediate medium.

[0035] The present application provides a file management method, which can be applied to processors of various system platforms, computer terminals or various mobile devices. The method flow chart of the method is as follows: Figure 1 As shown, the method may include the following steps:

[0036] S101: Obtain a first configuration file of a target PLC.

[0037] In one implementation, when a file upload operation corresponding to the target PLC executed by the user is detected, an upload instruction is sent to the target PLC according to the file upload operation, and the target PLC uploads the first configuration file according to the upload instruction.

[0038] In the examples of this application, refer to Figure 2As shown in the structural diagram, the first configuration file uploaded by PLCs of different manufacturers can be obtained by the data processing end. The data processing end can be a PLC engineering management system. The PLC engineering management system can be an application software installed on the client or an operating terminal connected to multiple PLCs. Each PLC can be connected to the PLC engineering management system by wire or wirelessly.

[0039] S102: Parse the first configuration file according to the first structure corresponding to the manufacturer to which the target PLC belongs, and obtain relevant information of the first configuration file.

[0040] The relevant information of the first configuration file includes: at least one of program logic information, variable definition information, hardware configuration information, and communication configuration information.

[0041] Among them, the program logic information includes the main part of the PLC program (similar to the main function in a computer program) and the main control logic of the entire automation process.

[0042] The variable definition information includes a variable table, which defines various variables used in the PLC program, such as input variables (such as sensor signals), output variables (such as motor control signals), intermediate variables (used for calculations and logical judgments within the program), etc.; the data type of the variable (such as Boolean, integer, real number, etc.) and storage address are also determined in the variable table; for example, the signal of a temperature sensor is defined as a real number input variable, and its storage address may correspond to a certain input register of the PLC.

[0043] The communication configuration information includes network parameters such as communication protocol, IP address (for Ethernet communication), baud rate (for serial communication), etc.; the network parameters are related parameters for PLC to communicate with other devices (such as host computer, other PLCs or intelligent instruments).

[0044] Hardware configuration information includes PLC input and output information, power supply information, communication module information, etc.

[0045] In the embodiment of the present application, for the first configuration files of PLCs belonging to different manufacturers, the first structure corresponding to each manufacturer is obtained respectively, and the first configuration file of the PLC belonging to the manufacturer is parsed according to the first structure corresponding to each manufacturer.

[0046] In one embodiment, according to the first structure corresponding to the manufacturer to which the target PLC belongs, the specific implementation process of parsing the first configuration file may be: obtaining the PLC manufacturer information and / or CPU model information contained in the first configuration file; determining the manufacturer to which the target PLC belongs based on the PLC manufacturer information and / or CPU model information; obtaining the first structure corresponding to the manufacturer from a preset database; parsing the first configuration file according to the first structure to obtain relevant information of the first configuration file.

[0047] Among them, the first structure is the data format used to manage relevant configuration data in the target PLC. The manufacturer sets the PLC-related configuration parameters when shipping the PLC, which includes the data format used to manage relevant configuration data. When the PLC uploads the configuration data, the PLC generates a corresponding first configuration file based on the data format it supports.

[0048] After obtaining the first configuration file, the PLC manufacturer information and / or CPU model information are obtained from the first configuration file, the PLC manufacturer information includes information such as the manufacturer name and related identifiers, and the CPU model information includes the model identifier, etc. After obtaining the PLC manufacturer information and / or the CPU model information, the first structure corresponding to the manufacturer can be searched in a preset database according to the manufacturer name in the PLC manufacturer information and / or the model identifier in the CPU model information.

[0049] Among them, the preset database contains structures of various manufacturers including this manufacturer. Specifically, the preset database may also include information tables related to each structure, and the information table is used to record the correspondence between PLC manufacturer information and / or CPU model information and the structure; or, the structure of each manufacturer contained in the preset database may carry PLC manufacturer information and / or CPU model information related to the manufacturer.

[0050] S103: Save the relevant information according to the preset second structure.

[0051] Among them, the saved related information is editable information.

[0052] Optionally, the specific implementation process of saving the relevant information according to the second structure may be: converting the format of the relevant information according to the second structure; and saving the relevant information in the converted format to a corresponding interface.

[0053] In an embodiment of the present application, the relevant information obtained by parsing the first configuration file includes at least one of program logic information, variable definition information, hardware configuration information, and communication configuration information. Each type of relevant information corresponds to an interface, and each interface caches the corresponding relevant information. When the relevant information needs to be edited or viewed, the relevant information can be obtained by calling the interface to process the relevant information. That is, after the relevant information is saved according to the preset second structure, if a processing request sent by the user is received, the calling interface maps the relevant information in the converted format to a preset display interface, and the processing request is a request to process the relevant information in the converted format.

[0054] The second structure is a private data format supported by the data processing end. When the data processing end needs to process any information, the data format of the information needs to be converted according to the second structure. The data format of the second structure can be the data format of the ap16 file format.

[0055] S104: When the saved related information is edited, the edited related information is translated into a second configuration file according to the first structure.

[0056] In an embodiment of the present application, a user can view, edit, and process relevant information. If the user edits the relevant information, the relevant information is updated according to the user's editing results. At this time, the edited relevant information needs to be sent to the target PLC as a new configuration. Therefore, to ensure that the target PLC can normally receive the edited relevant information, the edited relevant information needs to be translated into a second configuration file, and the second configuration file is downloaded to the target PLC, so that the target PLC updates the configuration version according to the second configuration file.

[0057] The present application can obtain the first configuration files of the target PLCs of different manufacturers, and parse the first configuration files according to the first structures corresponding to each manufacturer, so as to obtain the relevant information of the first configuration files of the PLCs of different manufacturers. After obtaining the relevant information, the format conversion and saving can be uniformly performed according to the second structures, so as to realize the unified management of each configuration file. After the saved relevant information is edited, the edited relevant information is translated according to the original first structures, so that the second configuration file obtained after the translation is consistent with the data format of the first configuration file before parsing.

[0058] By using the method provided by the present application, it is not necessary to deploy corresponding configuration tools for different manufacturers. By storing the structures of different manufacturers in the database, when obtaining any configuration file, it is only necessary to obtain the PLC manufacturer information and / or CPU model information in the configuration file to obtain the manufacturer to which the PLC that uploaded the configuration file belongs, and then obtain the corresponding first structure from the database. After parsing the configuration file according to the first structure to obtain relevant information, it is uniformly saved according to the second structure to achieve unified management of the relevant information of the configuration file. After completing the editing of the relevant information, the relevant information is translated into the configuration file according to the first structure, which can achieve simultaneous management of the configuration files of PLCs of different manufacturers, and can also perform parsing and translation respectively according to the differences in the structures between the configuration files corresponding to different manufacturers, thereby improving the management efficiency of the automation control system.

[0059] In one embodiment, after obtaining the relevant information, the relevant information is converted into a format according to the second structure through an interface corresponding to the relevant information and then cached. The user can subsequently use the interface to obtain the relevant information in the converted format. The specific method of calling the relevant information can be: upon receiving a processing request sent by the user, the interface is called to map the relevant information in the converted format to a preset display interface. The processing request is a request to process the relevant information in the converted format.

[0060] Among them, the data processing end may support the processing of different data formats, but among the various data formats supported by the data processing end, there may be some data formats that do not support display. Therefore, the second structure in the present application can be a data format that can be used for display among the various private data formats supported by the data processing end. When the user needs to process the relevant information, an operation button can be displayed on the display interface, and the user issues a processing request for processing the relevant information in the converted format through the operation button. Since different relevant information corresponds to different interfaces, when the user only issues a processing request for a certain relevant information, it is only necessary to call the interface corresponding to the relevant information to map the relevant information to the display interface.

[0061] For example, the relevant information obtained after parsing the first configuration file includes: communication configuration information, program logic information and variable definition information. After the communication configuration information, program logic information and variable definition information are format-converted according to the second structure, they are saved to the corresponding interfaces respectively (i.e., the communication configuration information in the converted format is saved to the interface corresponding to the communication configuration information, the program logic information in the converted format is saved to the interface corresponding to the program logic information, and the variable definition information in the converted format is saved to the interface corresponding to the variable definition information); when the user needs to edit the variable definition information in the converted format, the user only needs to call the interface corresponding to the variable definition information to map the variable definition information in the converted format to the display interface.

[0062] Optionally, after the user completes editing the relevant information in the converted format on the display interface, the user can perform an edit completion operation on the display interface. If the user also needs to edit the next relevant information in the converted format on the display interface, then continue to request the processing request corresponding to the next relevant information in the converted format without performing the edit completion operation. When the data processing end detects that the user performs the edit completion operation, the edited relevant information is translated into a new configuration file (i.e., a second configuration file) according to the first structure, and the new configuration file is downloaded to the PLC to update the configuration of the PLC.

[0063] Based on the method of the above embodiment, the process of uploading and downloading configuration files between the data processing end and the PLC can be as follows: Figure 3 As shown, in Figure 3 In the embodiment of the present invention, when the user needs to maintain and process the configuration of the PLC, the file upload operation is performed, and the data processing end sends a file upload instruction to the PLC according to the file upload operation; after receiving the file upload instruction, the PLC generates a first configuration file according to the first structure supported by the PLC, and uploads the first configuration file. After obtaining the first configuration file uploaded by the PLC, the data processing end determines the manufacturer to which the PLC belongs, and obtains the first structure of the manufacturer from the database, so as to parse the first configuration file according to the first structure and obtain relevant information. The relevant information is formatted according to the second structure private to the data processing end and saved to the corresponding interface. When the user needs to edit the relevant information, a processing request is sent to the data processing end, and the data processing end calls the interface to map the relevant information in the converted format to the display interface, and the user edits the relevant information through the display interface. When the user completes editing the relevant information, the edited relevant information is translated according to the first structure, and the second configuration file obtained by the translation is downloaded to the PLC.

[0064] By setting up a database, structures of different manufacturers can be saved, so that when uploading configuration files according to PLCs of different manufacturers, they can be parsed according to the corresponding structures respectively, without setting up configuration tools for each manufacturer. At the same time, the relevant information obtained after parsing can be uniformly managed according to the second structure. After completing the editing of the relevant information, the relevant information can be translated into a configuration file according to the original first structure and downloaded to the PLC, thereby updating the configuration of the PLC. By applying the method provided in this embodiment, the management of configuration files of different manufacturers can be realized, and the management efficiency of each configuration file can be improved.

[0065] In one embodiment of the present application, in order to facilitate the user to process the relevant information, after the relevant information is converted into a format and saved in a corresponding interface, the relevant information can be processed by calling the interface. However, in the processing process, in order to ensure the security of the information, it is necessary to set the user's relevant permissions for processing the relevant information. Therefore, refer to Figure 4 As shown in the flowchart, the specific process of calling the interface to map the relevant information to the preset display interface may include the following steps:

[0066] S401: Check whether the user has the authority to process the relevant information in the converted format.

[0067] In this application, the user's processing rights for relevant information can be authorized through a preset management terminal. The management terminal can be managed by an intermediate administrator. The intermediate administrator has the authority to assign a junior administrator. When a user needs to process relevant information, the intermediate administrator can set the user as a junior administrator through the management terminal, and the management terminal sets the corresponding permission identifier. The permission identifier is used to limit the scope of authority of the junior administrator.

[0068] Optionally, checking whether the user has the authority to process the relevant information in the converted format may specifically be: obtaining the user's authority identifier, determining the user's authority scope through the authority identifier, and if the authority scope includes processing the relevant information, it indicates that the user has the authority to process the relevant information, otherwise the user does not have the authority to process the relevant information. If the user has the authority to process the relevant information, then continue to execute S402; otherwise, execute S403.

[0069] S402: Calling an interface to map the relevant information in the converted format to a display interface.

[0070] S403: Sending an authorization notification corresponding to the user to a preset management end, so that the management end grants the user the authority to process the relevant information in the converted format based on the authorization notification.

[0071] The management end may be a rights management program built into the data processing end, or a client connected to the data processing end.

[0072] In this application, when the management end grants a user the authority to process relevant information, it can set a corresponding permission identifier to limit the user's authority scope through the permission identifier to prevent the user from processing other relevant information that is not within the user's authority scope, thereby causing information leakage or tampering.

[0073] Optionally, in addition to checking the user's authority when the user needs to process relevant information, the user's authority may also be checked when the user requests to upload the PLC configuration file and downloads the configuration file to the PLC.

[0074] Optionally, in addition to receiving the relevant authorization operations of the intermediate administrator, the management terminal can also allow the senior administrator to manage the junior administrator and the intermediate administrator through the management terminal, and the senior administrator has a log record of the administrator's operation behavior (for example: when the intermediate administrator authorizes the junior administrator through the management terminal, the senior administrator records the relevant operations of the intermediate administrator through the management terminal). In addition, the management terminal can also generate the operation log corresponding to the above-mentioned S101-S104 process according to the log generation instruction sent by the senior administrator.

[0075] Based on the above embodiment, the management terminal can receive corresponding instructions sent by three levels of administrators, and the three levels of administrators can be primary, intermediate and senior respectively. The primary administrator can apply for the authority to configure the PLC through the management terminal, including uploading, downloading and editing the PLC configuration file; the intermediate administrator has the authority to assign the primary administrator, and the intermediate administrator can only allow the download program to a certain PLC IP address when configuring the primary administrator; the senior administrator has the ability to generate log records of the operation behaviors of the primary and intermediate administrators through the management terminal, which is convenient for subsequent tracing. The primary administrator user is created by the intermediate administrator, and the corresponding strategy is assigned. The strategy can be to set the control to allow or block the distribution of a certain manufacturer's PLC configuration file; allow or block the download control of the IP, allow or block the distribution of the variable address of DB1 (where DB stands for Data Block) containing the variable address, etc.

[0076] In one embodiment of the present application, in order to further ensure the security of information, it is necessary to perform a communication status check during the process of downloading the second configuration file to the target PLC. Therefore, after translating the edited relevant information into the second configuration file according to the first structure, it also includes: based on a preset communication protocol, detecting whether the communication state with the target PLC is normal; if the communication state with the target PLC is normal, downloading the second configuration file to the target PLC.

[0077] Optionally, when the second configuration file needs to be downloaded to the target PLC, the PLC to which the second configuration file needs to be downloaded may be determined through the PLC manufacturer information and / or CPU model information to avoid downloading the second configuration file to other PLCs.

[0078] In an embodiment of the present application, when downloading the second configuration file to the target PLC, it is determined whether the communication state with the target PLC is normal according to the communication protocol to avoid the loss of some files due to file transfer in an abnormal communication state, thereby improving the security of information.

[0079] According to the method provided in the above embodiment, the process of parsing, saving and translating the configuration file and downloading it has the following implementation scenarios:

[0080] The Siemens PLC engineering management system has a built-in Siemens PLC configuration file structure library (i.e., database), which can parse the configuration file according to the structure of the Siemens PLC (i.e., using the same parsing method as the Siemens PLC programming software). The Siemens PLC uploads the configuration file to the PLC engineering management system, where the PLC engineering management system and the Siemens PLC can establish communication through Ethernet; according to the model information in the file, it is determined that the manufacturer corresponding to the file is the Siemens PLC, and the configuration file is parsed through the built-in Siemens PLC structure library. The various related information obtained by parsing include program logic information, variable definition information, hardware configuration information, and communication configuration information. If the PLC needs to communicate with other devices (such as a host computer, other PLCs, or smart meters), the configuration file will contain network connection parameters. This includes communication protocol TCP / IP, IP address, and port number. After parsing the above data, encapsulate it into 4 interfaces, map the data in the 4 interfaces according to the private structure of the PLC engineering management system, and store the data in the ap16 format file. The stored information is displayed through the PLC engineering management system display interface. Users can intuitively adjust and edit the program logic information, variable definition information, hardware configuration information, and communication configuration information according to the program specifications and syntax of the PLC engineering management system (because different PLC programming software may have some differences in the code representation method). After editing, compile the program. If a compilation error occurs, an error message will be given. Users can modify it according to the error message until the compilation is successful and it can be saved in an AP16 format file. Before issuing, confirm that the communication between the PLC engineering management system and the Siemens PLC is normal, select the correct download target PLC device, determine which manufacturer's PLC the file corresponds to based on the PLC manufacturer information and CPU model information in the file, and then translate the configuration file content into the built-in manufacturer data structure based on the built-in manufacturer structure library and download it to the PLC.

[0081] Based on the same inventive concept, the present application also provides a PLC engineering management system 500. Figure 5 , Figure 5 This is a structural block diagram of a PLC engineering management system 500 provided in an embodiment of the present application. The PLC engineering management system 500 includes: an acquisition unit 501, a parsing unit 502, a storage unit 503 and a translation unit 504.

[0082] The acquisition unit 501 is used to acquire a first configuration file of a target PLC.

[0083] The parsing unit 502 is used to parse the first configuration file according to the first structure corresponding to the manufacturer to which the target PLC belongs, and obtain relevant information of the first configuration file.

[0084] The saving unit 503 is used to save the relevant information according to a preset second structure, wherein the saved relevant information is editable information.

[0085] The translation unit 504 is used to translate the edited relevant information into a second configuration file according to the first structure when the edit of the saved relevant information is completed.

[0086] In an optional embodiment, the parsing unit 502 is specifically used to obtain the PLC manufacturer information and / or CPU model information contained in the first configuration file; determine the manufacturer to which the target PLC belongs based on the PLC manufacturer information and / or the CPU model information; obtain a first structure corresponding to the manufacturer from a preset database, the preset database containing structures of various manufacturers including the manufacturer; parse the first configuration file according to the first structure to obtain relevant information of the first configuration file.

[0087] In an optional embodiment, the saving unit 503 is specifically used to convert the format of the relevant information according to the second structure; and save the relevant information in the converted format to a corresponding interface.
