[0019] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0020] To better understand the technical solutions of the present application, the following will be described in detail in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0021] The main solution of the embodiment of the present application is: based on a preset desktop application framework, a desktop application and a preset embedded relational database are built in an industrial device, wherein the preset embedded relational database supports offline data caching; when a network interruption is detected, the device offline operation data corresponding to the industrial device is collected in real time through the desktop application; the device offline operation data is stored in the preset embedded relational database; and the industrial device is managed through the desktop application based on all the device offline operation data stored in the preset embedded relational database.

[0022] Since most industrial device management systems in the prior art highly rely on an external network to implement device communication and data synchronization, once the network is interrupted or attacked, it is easy to cause the system to crash or data to be lost, and thus the device control cannot continue.

[0023] The present application provides a solution. By building a desktop application and a preset embedded relational database that supports offline data caching in the desktop end of an industrial device, it is possible to collect device offline operation data through the desktop application when the network is interrupted, and manage the industrial device through the desktop application based on all the device offline operation data stored in the preset embedded relational database, thereby solving the technical problem that the management of industrial devices in the prior art usually relies on a continuous network connection and usually cannot continue data collection and device management when the network is interrupted.

[0024] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication, and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device, a device management system, etc. that can implement the above functions. Hereinafter, taking a device management system as an example (hereinafter referred to as the system), this embodiment and the following embodiments will be described.

[0025] Based on this, the embodiment of the present application provides a device management method, referring to Figure 1 , Figure 1 which is a schematic flowchart of the first embodiment of the device management method of the present application.

[0026] In this embodiment, the device management method includes steps S10 to S40: Step S10: Build a desktop application and a preset embedded relational database in the industrial device based on a preset desktop application framework, where the preset embedded relational database supports offline data caching.

[0027] It should be noted that the above-mentioned preset desktop application framework can be a framework for building cross-platform desktop applications, which allows users to use HTML (Hyper Text Markup Language), CSS (Cascading Style Sheets), and JavaScript (front-end technology stack) to build desktop applications that are compatible with Windows, macOS, and Linux at the same time. In this embodiment, the preset desktop application framework can be the Electron framework. The Electron framework is an open-source framework for building cross-platform desktop applications using JavaScript, HTML, and CSS. It can simplify the process of Web and desktop development. At the same time, by combining Chromium and Node.js, the Electron framework enables users to write desktop applications with front-end technologies and access the underlying functions of the operating system. Compared with traditional device management systems such as the PLC monitoring system developed based on C# that only supports the Windows platform and cannot adapt to industrial terminals such as Linux or macOS, the desktop application of the device constructed using the Electron framework in this embodiment can be seamlessly deployed on Windows, macOS, and Linux platforms, thus improving the flexibility and cross-platform support ability of the system, and at the same time saving development and maintenance costs.

[0028] It can be understood that the above-mentioned industrial device can be any device used for industrial production; correspondingly, the above-mentioned desktop application can be software deployed on the local computer or industrial control panel of the industrial device for monitoring, controlling, or managing the industrial device.

[0029] It should be noted that the above-mentioned preset embedded relational database can be a database for storing all data generated during the operation of the industrial device, where the preset embedded relational database can support the caching of offline data. In this embodiment, the preset embedded relational database can be the SQLite database. The SQLite database is a lightweight open-source relational database that can be stored in the local device in the form of a single file, can run without an independent server process, and supports standard SQL syntax, which is suitable for embedded systems and lightweight applications.

[0030] In practical applications, the system can use the SQLite database as the local database and combine it with the Electron framework to package data storage and desktop applications into the desktop of industrial devices. Since the SQLite database supports data offline caching, even without a network connection, the desktop of industrial devices can still collect data and control devices, and can cache the collected data in the local SQLite database.

[0031] Step S20: When a network interruption is detected, the desktop application is used to collect the device offline operation data corresponding to the industrial device in real time.

[0032] It should be understood that the above device offline operation data can be data generated, stored, or processed by industrial devices in a state without a network connection. In this embodiment, the system can use Node.js in the main process to perform data interaction with a PLC (such as Siemens S7, Omron FINS) through a Socket protocol (such as TCP / UDP) and collect the device offline operation data generated by industrial devices in a state without a network connection in real time. Among them, Node.js is a JavaScript runtime environment based on the Chrome V8 engine, which allows users to write server-side application programs using JavaScript.

[0033] Step S30: Store the device offline operation data in the preset embedded relational database.

[0034] It can be understood that since the preset embedded relational database supports offline data caching, even when the industrial device has no network connection, the device offline operation data generated, stored, or processed by the industrial device can be stored in the preset embedded relational database.

[0035] Step S40: The desktop application is used to manage the industrial device based on all the device offline operation data stored in the preset embedded relational database.

[0036] In this embodiment, even when the industrial device is currently in a state without a network connection, the system can still manage the industrial device through the desktop application based on the device offline operation data stored in the preset embedded relational database. Specifically, Node.js in the system communicates bidirectionally with the PLC device through WebSocket to perform device control operations, such as controlling the start, stop, and parameter adjustment of the device, and obtaining the status information in real time. In addition, the system can also implement device control and data interaction through the built-in HTTP server and WebSocket in the Electron framework. The front end operates the device through the UI and provides real-time feedback on the device status.

[0037] It should be noted that in this embodiment, the system can use the Node.js background for multi-threaded data processing. Specifically, Node.js can start child processes through the child_process module to avoid blocking the main process and ensure smooth response of the application. At the same time, the Node.js background can split and distribute data processing tasks to multiple child processes for parallel execution, and the main process is responsible for managing the scheduling of child processes. Additionally, it can avoid system overload by limiting the number of child processes to ensure efficient use of resources. Moreover, the Node.js background can also collect and process PLC data in real time. Among them, the child processes are responsible for heavy calculations, and the main process is responsible for updating the interface. When an error occurs in a child process, the main process can be notified through the IPC mechanism and error handling can be executed to ensure system stability.

[0038] In specific implementation, the system in this embodiment can ensure that when the network connection of the device is disconnected, the desktop end of the device can still continue to monitor and collect data of the device, and automatically synchronize the data after the network is restored, ensuring the reliability and stability of the system. At the same time, the system can use the SQLite local database to store and cache data, thereby avoiding the loss of device management functions caused by network interruption, and then providing a more stable offline usage experience. Also, by combining the Electron framework and the NestJS framework, the system realizes two-way collaboration between the desktop end and the Web server end, enhancing the flexibility and cross-platform support ability of the system.

[0039] Further, the step S40 includes: Step S401: Display all the device offline operation data stored in the preset embedded relational database to the control interface corresponding to the industrial device.

[0040] It should be understood that the above control interface can be an interface for operating and monitoring the device. In this embodiment, the system can build the UI through HTML, CSS, and JavaScript to display the device status and control panel in real time to ensure convenient operation.

[0041] Step S402: When detecting a user operation instruction triggered by the user based on the control interface, determine the operation to be performed on the industrial device based on the user operation instruction. The operation of the user is in real-time communication with the industrial device through the data transmission protocol built into the preset desktop application framework.

[0042] It should be noted that the above operation to be performed can be an operation that the user instructs the industrial device to perform. For example, starting, stopping, parameter adjustment, etc. of the device are not limited in this embodiment. The above data transmission protocol can be a protocol for data transmission with the device. In this embodiment, the user operation can be in real-time communication with the background through the WebSocket protocol.

[0043] Step S403: Control the industrial device to perform the operation to be performed through the desktop application, so as to manage the industrial device.

[0044] In practical applications, users can control the device by operating the control panel of the device. In this embodiment, since all the offline operation data of the device in the state of no network connection is displayed on the control panel of the device, users can control the stop, pause and parameter adjustment of the device according to the offline operation data of the device, that is, users can generate user operation instructions based on the offline operation data of the device displayed on the control panel. At this time, the system can determine the operation to be performed on the device according to the user operation instructions, and control the industrial device to perform the operation to be performed through the desktop application.

[0045] Further, before the step S403, it further includes: determining whether the operation to be performed belongs to a preset sensitive operation; if so, authenticating the user through a preset authentication method; when the authentication is passed, performing dynamic authentication on the user through a preset dynamic authentication method; if the authentication is passed, executing the step of controlling the industrial device to perform the operation to be performed through the desktop application to manage the industrial device.

[0046] It should be noted that the above preset sensitive operation may be a key operation of the PLC control command in the device, for example, operations such as defining device logic, data processing and communication interaction, and this embodiment does not limit this.

[0047] It should be understood that the above preset authentication method may be a method of authenticating the user through the user name and password of the user. The above preset dynamic authentication method may be a method of authenticating the user through a dynamic verification code.

[0048] In practical applications, when the operation to be performed instructed by the user on the device involves sensitive operations, in order to ensure the security of the device, the system can perform two-factor authentication on the user's identity. For example, in this embodiment, the system can first perform the first layer of identity authentication on the user through the user name and password of the user. However, since the user name and password alone are vulnerable to brute force cracking or social engineering attacks, when the first layer of identity authentication is passed, a second layer of authentication can also be performed on the user to enhance security. Specifically, after the user enters the correct user name and password, the system can require the user to provide a dynamic verification code, which can be generated by text message, email or an authentication application (such as Google Authenticator). This verification code usually has timeliness and one-time use, so as to ensure that only the currently authorized user can complete the operation.

[0049] Further, after the step S40, the method further includes: when detecting that the network is restored, comparing the device offline operation data with the device operation log, and performing data synchronization according to the comparison result; during the data synchronization process, processing data conflicts according to timestamps until the synchronization of the device offline operation data is completed.

[0050] It should be noted that when the network of the industrial device is restored, the system can automatically perform differential data synchronization to ensure data consistency. In this embodiment, the system can compare the device offline operation data with the device operation log and perform data synchronization. During the data synchronization process, the system can preferentially solve data conflicts through timestamps to ensure data consistency during synchronization.

[0051] Further, after the step S403, the method further includes: when detecting a component dragging instruction, generating an interface configuration file based on the component dragging instruction; determining the style attributes corresponding to all interface components in the control interface according to the interface configuration file; and updating the control interface based on the style attributes.

[0052] It can be understood that the above component dragging instruction can be an instruction triggered when the user drags a component in the control interface of the device.

[0053] It should be understood that the above interface configuration file can be a file used to define and configure the control interface of the device. The above style attributes can be attributes such as the size, color, and position of the component.

[0054] In practical applications, the user can generate a JSON-format interface configuration file by dragging components on the control interface of the device and store it in the database. The configuration file can define the attributes such as the size, color, and position of the components adjusted by the user, enabling the system to update the control interface of the device according to the attributes such as the size, color, and position of the components configured by the user, helping the user optimize the interface and meet visual and functional requirements. In addition, the user can bind the interface components to PLC data points to achieve real-time data interaction and control functions. In this embodiment, interface customization is performed based on the interface configuration file, enabling the user to complete interface customization without modifying the code. At the same time, the interface supports multi-language switching, and the interface text and alarm information can be managed through independent language packs, thus meeting multi-functional requirements.

[0055] This embodiment provides a device management method, which discloses building a desktop application and a preset embedded relational database in an industrial device based on a preset desktop application framework. Among them, the preset embedded relational database supports offline data caching; when a network interruption is detected, the desktop application is used to collect the device offline operation data corresponding to the industrial device in real time; the device offline operation data is stored in the preset embedded relational database; the desktop application is used to manage the industrial device based on all the device offline operation data stored in the preset embedded relational database; since the desktop in the industrial device in this embodiment is built with a desktop application and a preset embedded relational database that supports offline data caching, it is possible to collect device offline operation data through the desktop application during a network interruption, and manage the industrial device through the desktop application based on all the device offline operation data stored in the preset embedded relational database, thus solving the technical problem in the prior art that the management of industrial devices usually depends on a continuous network connection and usually cannot continue data collection and device management during a network interruption.

[0056] Based on the first embodiment of this application, in the second embodiment of this application, for the same or similar content as in the above-mentioned first embodiment, reference can be made to the above introduction and will not be repeated hereinafter. On this basis, please refer to Figure 2 , Figure 2 which is a schematic flowchart provided for the second embodiment of the device management method of this application.

[0057] In this embodiment, the method further includes steps S100 to S102: Step S100: The client server performs data interaction with the desktop of the industrial device based on a preset network interface to obtain the production data corresponding to the production task in the industrial device, and the preset network interface is generated based on the Representational State Transfer (REST) architecture.

[0058] It can be understood that the above-mentioned preset network interface can be an interface for realizing data transmission between the client server and the industrial device. In this embodiment, the preset network interface can be a network interface generated based on the Representational State Transfer (REST) architecture. In practical applications, a network interface based on the REST style can use methods of the HTTP protocol (Hypertext Transfer Protocol) (such as GET, POST, PUT, DELETE) to operate on resources, and has characteristics such as cross-platform compatibility, easy testing and debugging, and support for caching.

[0059] It should be understood that the above production tasks can be the set of work instructions currently being executed by industrial equipment; correspondingly, the above production data can be the data generated when executing or processing the production tasks.

[0060] Step S101: When receiving a production scheduling request, determine the production progress of the production task according to the production data.

[0061] It can be understood that the above production scheduling request can be a request for scheduling the production tasks currently being carried out by industrial equipment.

[0062] Step S102: Perform production scheduling on the production task based on the production progress.

[0063] In practical applications, the system can design a microservice architecture through the NestJS framework and adopt the CQRS (Command Query Responsibility Segregation) mode to separate read and write operations to ensure stability under high concurrency. At the same time, the Web side exchanges data with the desktop side through the RESTful API (i.e., the above preset network interface), which supports real-time viewing of the device status, sending production work orders, monitoring the device execution situation, and feeding back data to the ERP system. In addition, managers can view the production progress through the Web side and generate production scheduling requests according to the production progress to schedule production tasks, ensuring the timeliness and transparency of production scheduling.

[0064] In this embodiment, it is disclosed that data interaction is performed between the client server and the desktop side of industrial equipment based on a preset network interface to obtain production data corresponding to production tasks in the industrial equipment. The preset network interface is generated based on the Representational State Transfer architecture; when receiving a production scheduling request, determine the production progress of the production task according to the production data; perform production scheduling on the production task based on the production progress; since this embodiment can determine the production progress according to the production data corresponding to the production tasks in the industrial equipment and schedule production tasks based on the production progress, the timeliness and transparency of production scheduling can be ensured.

[0065] Based on the first embodiment and / or the second embodiment of the present application, in the third embodiment of the present application, for the same or similar content as the above embodiments, reference can be made to the above introduction and will not be repeated hereinafter. On this basis, please refer to Figure 3 , Figure 3 which is the flowchart provided for the third embodiment of the device management method of the present application.

[0066] In this embodiment, the method further includes steps S200 to S203: Step S200: When it is detected that the industrial device to be managed is connected, generate a device identifier corresponding to the industrial device to be managed based on the device information corresponding to the industrial device to be managed.

[0067] It should be understood that the above-mentioned industrial device to be managed can be any industrial device that needs to be connected to the system for unified management. Among them, the device information corresponding to the industrial device to be managed can be the unique identifier corresponding to the device. In this embodiment, the unique identifier corresponding to the device can be generated by combining the IP address and MAC address of the device, so as to ensure that each device has a unique identifier in the system.

[0068] Step S201: Search for the protocol configuration information corresponding to the industrial device to be managed according to the device identifier.

[0069] It should be noted that the above-mentioned protocol configuration information can be the industrial protocol information supported by the industrial device to be managed.

[0070] Step S202: Determine the protocol parsing template corresponding to the industrial device to be managed according to the protocol configuration information.

[0071] It should be noted that the above-mentioned protocol parsing template can be a structured definition template that converts the original device communication data (such as binary stream, hexadecimal message) into readable information according to the protocol rules, which usually includes field splitting, data type mapping and verification rules.

[0072] Step S203: Establish a communication connection with the industrial device to be managed by loading the protocol parsing template.

[0073] In practical applications, each device usually supports multiple industrial protocols. Therefore, the system can configure multiple connection information for each device. These connection information can include protocol types (such as Modbus, OPC UA, Ethernet / IP, etc.), communication ports, data acquisition points, read / write commands, etc. When the device is connected, the system can search for the protocol configuration of the device according to the unique identifier of the device, then dynamically load the corresponding protocol parsing template, and establish a connection with it. In addition, each device can also be configured with acquisition points (such as sensor data, status registers, alarm points, etc.). By configuring these points, the accurate acquisition and monitoring of device data can be ensured.

[0074] In this embodiment, in addition to protocol configuration, the commissioning interface (i.e., the operation interface) of the device can also be customized through configuration. Users can design and configure the commissioning interface of the device according to the characteristics of the device and operation requirements. When the industrial computer is running, after the device is connected to the system and successfully matched by the unique value generated based on the IP address and MAC address, the system can not only load the protocol configuration of the device, but also load the commissioning interface associated with the device. Among them, the commissioning interface of the device can include: parameter setting, device status display, alarm information, etc. Users can manually debug and operate the device according to actual needs.

[0075] In this embodiment, when it is detected that a to-be-managed industrial device is connected, a device identifier corresponding to the to-be-managed industrial device is generated based on the device information corresponding to the to-be-managed industrial device; protocol configuration information corresponding to the to-be-managed industrial device is found according to the device identifier; a protocol parsing template corresponding to the to-be-managed industrial device is determined according to the protocol configuration information; a communication connection with the to-be-managed industrial device is established by loading the protocol parsing template, so that the to-be-managed industrial device can be uniformly managed subsequently, improving the standardization of industrial device management.

[0076] It should be noted that the above examples are only for understanding the present application and do not constitute a limitation on the device management method of the present application. Based on this technical concept, more forms of simple transformation are within the protection scope of the present application.

[0077] The present application also provides a device management device. Please refer to Figure 4 , and the device management device includes: An application construction module 10, configured to construct a desktop application and a preset embedded relational database in the industrial device based on a preset desktop application framework, where the preset embedded relational database supports offline data caching; A data acquisition module 20, configured to, when a network interruption is detected, collect device offline operation data corresponding to the industrial device in real time through the desktop application; A data storage module 30, configured to store the device offline operation data into the preset embedded relational database; A device management module 40, configured to manage the industrial device through the desktop application based on all the device offline operation data stored in the preset embedded relational database.
