Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0021] In current embedded development within the industrial internet field, monitoring, debugging, and deploying applications on remotely deployed devices (such as ARM architecture development boards and industrial control computers) is a common but complex requirement. Traditional solutions suffer from at least the following problems: 1. Limited and non-real-time monitoring methods: Traditional solutions typically rely on logs or status data reported by the device, which cannot provide real-time visual feedback on the physical status of the device on site.

[0022] 2. Complex and insecure access methods: Remote access to device shells typically relies on the Secure Shell protocol (SSH protocol). Operators need to use separate SSH client tools and configure complex network policies, such as VPN access or port forwarding, which increases the complexity and barrier to entry for operations.

[0023] 3. Inefficient application deployment and management: Running and testing applications (such as Qt programs) on industrial equipment usually requires uploading files via SCP / FTP and then manually executing commands via SSH.

[0024] 4. Poor system integration: Monitoring, terminal operation, application management and other functions are scattered in different tools and interfaces, which cannot form an integrated operation platform, resulting in low debugging efficiency and high learning cost.

[0025] To at least address the technical problem of how to visualize and remotely manage industrial equipment in the prior art, this application provides an industrial equipment remote management system and method that can provide real-time visual feedback on industrial equipment through a front-end web browser.

[0026] The first embodiment of this application provides a remote management system for industrial equipment, such as... Figure 1 The system includes: front-end 101, server 102, and proxy 103.

[0027] Front-end 101 maintains a long connection with server 102 via the WebSocket protocol; proxy 103 is deployed on the local area network of industrial equipment, connects to the industrial equipment, and establishes a long connection with server 102; server 102 controls proxy 103 based on the request instructions from front-end 101, and sends the response data returned by proxy 103 to front-end 101 according to the WebSocket protocol; front-end 101 is used to display the video stream of proxy 103 in real time.

[0028] The WebSocket protocol is a full-duplex communication protocol based on the Transmission Control Protocol (TCP), which can solve the problem of real-time bidirectional communication between a web browser and a server. Industrial equipment can be an embedded development board or an industrial control computer. The industrial equipment can connect to the agent via USB, serial port, network cable, etc. The agent can connect to multiple industrial devices in a local area network. The agent can also connect to peripherals such as cameras, without limitation. The following embodiments of this application use the ITX-3568 development board as an example of industrial equipment for illustration, and do not represent a limitation on the industrial equipment.

[0029] In this system, the agent is deployed at the industrial equipment site and connected to the equipment. The agent establishes a long-term connection with the server, and the video stream from the agent can be displayed in real time on the front end. Since the front end maintains a long-term connection with the server via the WebSocket protocol, real-time visual feedback on the industrial equipment can be provided through the front-end's web browser. Furthermore, the server can control the agent based on the front end's request commands and send the response data returned by the agent to the front end according to the WebSocket protocol. Therefore, the front-end's web browser can serve as a unified console to realize remote management of industrial equipment, improving management efficiency.

[0030] In one embodiment, a schematic diagram of the industrial equipment remote management system is shown below. Figure 2 The front-end may include a real-time video monitoring module. The agent sends the video stream to the server; the server converts the video stream into an HTTP-FLV stream (an FLV format video stream transmitted based on the HTTP protocol) using its built-in video stream transcoding service module and then pushes it to the front-end; the front-end plays the HTTP-FLV stream through the real-time video monitoring module.

[0031] In this embodiment, the video stream can be a video stream collected by the proxy end, such as a video stream collected by the proxy end from the connected camera via the RTSP (RealTime Streaming Protocol). The proxy end sends the collected video stream to the server end, where the video stream transcoding service module converts the video stream into an HTTP-FLV stream and sends it to the front end. The front end uses a real-time video monitoring module, such as an FLV format video parsing and playback JavaScript library (FLV Format VideoParsing and Playback JavaScript Library, abbreviated as flv.js library), to pull and decode the HTTP-FLV stream. The flv.js library can directly play FLV format videos in a web browser via the HTML5 Video tag, achieving low-latency real-time monitoring screen display.

[0032] In one embodiment, the front end further includes an application management module. The application management module contains a list of applications, and the application packages corresponding to the application list are pre-uploaded to the server's database.

[0033] The front end sends a request command to the server through the application management module; the request command carries an application identifier; the server sends the request command to the proxy; the proxy controls the target application corresponding to the application identifier to run according to the request command; the video stream of the target application is forwarded to the front end through the server so that the running status of the target application can be displayed in real time in the real-time video monitoring module.

[0034] In this embodiment, application packages (such as compiled Qt executable files and resource files) can be pre-uploaded to the server's database for storage. The front end can obtain a list of applications that can run on industrial equipment through a standardized application programming interface (RESTful API). The front end sends a request command carrying an application identifier to the server through the application management module. The server sends the request command to the proxy end, which controls the target application corresponding to the application identifier to run according to the request command. The video stream of the target application is forwarded to the front end through the server so that the running status of the target application can be displayed in real time on the real-time video monitoring module.

[0035] For example, when a user clicks the "Run" button on application A in the application list of the application management module, the front end sends a JSON (JavaScript Object Notation) request command containing the "Application ID" and the "Action (run)" via WebSocket. After the server parses the command, it instructs the proxy to execute the corresponding startup script, completing the operation of application A. It should be understood that users can automate the deployment and lifecycle management of industrial equipment through operations on the application management module in their front-end web browser.

[0036] In one embodiment, the agent controls the target application corresponding to the application identifier to run according to the requested instructions, including: the agent determines whether the target application corresponding to the application identifier has been installed in the industrial equipment; if the target application is not installed in the industrial equipment, the agent downloads the target application from the server's database according to the application identifier and installs the target application in the industrial equipment; the agent controls the industrial equipment to start the target application and controls the target application to run according to the requested instructions.

[0037] In this embodiment, during the process of the agent controlling the target application corresponding to the application identifier to run according to the request instruction, the agent can determine whether the target application corresponding to the application identifier has been installed in the industrial equipment. If the target application is not installed in the industrial equipment, the agent can download the target application from the server's database according to the application identifier and install the target application in the industrial equipment. After the target application is installed, the agent controls the industrial equipment to start the target application and controls the target application to run according to the request instruction.

[0038] In one embodiment, the front end further includes a Web Shell terminal module. The front end sends debugging commands to the server via the Web Shell terminal module. The server forwards the debugging commands to the proxy, enabling the proxy to control the target application to execute the debugging commands. The debugging response of the debugging commands is sent to the front end via the server and displayed on the Web Shell terminal module.

[0039] In this embodiment, if debugging of applications in industrial equipment is required, debugging commands can be sent to the server via a Web Shell terminal module (e.g., xterm.js). The server then forwards the commands to a proxy, which controls the target application to execute the debugging commands and sends the debugging response back to the front-end Web Shell terminal module for display. Specifically, the front-end can send a request to establish a shell connection to the server via WebSocket. After a pseudo-terminal (PTY) is established between the server and the proxy, all character data is transmitted bidirectionally between the web browser and the industrial equipment via the WebSocket connection. A simulated terminal in the web browser can be built using xterm.js and its plugins (such as xterm-addon-fit). xterm.js is responsible for rendering the simulated terminal interface, handling keyboard input and output display, providing a user experience almost identical to the native terminal of the industrial equipment, without requiring the local installation of tools such as SSH clients.

[0040] In one embodiment, the server includes a WebSocket service module, a video stream transcoding service module, a proxy management module, a business logic module, and a database.

[0041] The WebSocket service module manages long-lived WebSocket connections with the front end; the video stream transcoding service module transcodes and encapsulates RTSP streams received from the proxy into HTTP-FLV streams; the proxy management module manages long-lived connection channels with the proxy; the business logic module handles front-end authentication, permission management, industrial equipment information management, and application package data management; and the database stores user information, industrial equipment information, and application packages.

[0042] In this embodiment, the server is the core and bridge of the system's business logic. It can handle requests from the front end and control the proxy end, and needs to have high concurrency and real-time communication capabilities. The server can use Node.js (based on the Express.js or Koa.js framework) or Go (Gin framework), both of which are very suitable for handling high-concurrency, I / O-intensive applications that connect via WebSocket.

[0043] The WebSocket service module can easily create WebSocket servers using the Socket.IO (based on Node.js) or gorilla / websocket (based on Go) libraries, manage a large number of persistent connections, and perform broadcasting, room management, and other functions. The video stream transcoding service module (e.g., using FFmpeg) can, upon receiving a video stream request, call FFmpeg to transcode and encapsulate the RTSP stream from the proxy into an HTTP-FLV stream in real time for playback by the frontend flv.js (real-time video monitoring module). The proxy management module manages long-lived connection channels with the proxies. The server maintains another long-lived connection channel with all proxies using either WebSocket or gRPC. This channel forwards control commands (such as Shell commands and application management commands) from the web frontend and receives status reports from the proxies. gRPC, due to its high performance and strongly typed interface, is a better choice than WebSocket in this scenario. The business logic module handles frontend user authentication, permission management, device information management, application package metadata management, and provides a standardized application programming interface (RESTful API) for connecting to the frontend and proxies. The database is used to store user information, industrial equipment information, and application packages, and can use MySQL or PostgreSQL databases.

[0044] In one embodiment, the agent includes: a device connector module, a video stream acquisition module, a power control module, and a communication module.

[0045] The device connector module is used to establish a connection with industrial equipment via a serial port library or an SSH library; the video stream acquisition module is used to acquire video streams from cameras connected to the agent and send the video streams to the server; the power control module is used to control the relays connected to the smart socket to achieve remote hard reboot of the industrial equipment; and the communication module is used to establish a connection with the server, receive and execute instructions sent by the server.

[0046] In this embodiment, the agent is a lightweight program deployed at the equipment site (e.g., in a workshop), responsible for interacting with industrial equipment or peripherals (cameras, smart sockets, etc.). The agent can be written in Python or Go, which offer good cross-platform compatibility and a rich ecosystem. The device connector module can establish a connection with industrial equipment (e.g., a development board) via a serial port library (e.g., pyserial) or a Secure Shell protocol (SSH) library (e.g., paramiko). The video stream acquisition module can read the image from a USB camera connected to the agent host or pull RTSP streams from a network camera and push them to the server via the OpenCV library or by directly calling FFmpeg commands. The power control module can control the relays connected to the smart socket via a general-purpose input / output interface (GPIO) library (e.g., RPi.GPIO, suitable for Raspberry Pi as the agent) or a network application programming interface (API), enabling remote hard reboot of the device. The communication module can use a WebSocket or gRPC client to establish a stable connection with the server, receive and execute commands. The agent can download application packages from the server according to server commands and execute corresponding start / stop scripts and other commands on the device via serial port / SSH.

[0047] In a specific embodiment, taking "running a Qt application demo" as an example, the workflow of this system is as follows: 1. User Login: Users open their browsers and log in to the system's web interface.

[0048] 2. Establish connection: After the front-end loads, it automatically establishes a connection with the server via WebSocket.

[0049] 3. View Video: When the user clicks "Start Video," the frontend sends a command via WebSocket. The server instructs the proxy to turn on the camera and convert it to an FLV stream using FFmpeg. The frontend flv.js then plays the stream.

[0050] 4. Select an application: The user selects a Qt application demo from the application list.

[0051] 5. Sending instructions: When the user clicks the "Run" button, the front end sends the instruction {action: "run", appId: "qt-demo-101"} via WebSocket.

[0052] 6. Command Routing: When the server receives a command, it forwards the command to the agent located on the target device through another gRPC channel established with the agent.

[0053] 7. Execution on the agent side: ① The agent downloads the application package from the server based on the application identifier appId (if it is not available locally).

[0054] ② The agent connects to the ITX-3568 development board via SSH.

[0055] ③ The agent executes the application's corresponding "startup script" (e.g., . / start_qt_demo.sh) on the development board.

[0056] 8. Results Feedback: After the application starts, its interface will be displayed on the screen connected to the development board. Users can observe the application's running effect in real time through the video monitoring module integrated into the web page.

[0057] 9. Terminal Interaction: For debugging, users can open the Web Shell terminal, enter commands, and transmit character data through the WebSocket channel, displaying the output in xterm.js.

[0058] The above embodiments of this application provide a highly integrated, secure, convenient, real-time, and efficient remote management system for industrial equipment. This system provides users with a unified console through a standard web browser, enabling real-time video monitoring of remote industrial equipment, web terminal interaction, and one-click deployment and management of applications, greatly improving the efficiency of remote debugging and maintenance of industrial equipment.

[0059] Based on the same technical concept, the second embodiment of this application provides a method for remote management of industrial equipment, characterized in that it is applied to the remote management system for industrial equipment described in any one of the first embodiments, wherein the front end maintains a long connection with the server via the WebSocket protocol, the proxy end is deployed in the local area network of the industrial equipment, the proxy end connects to the industrial equipment, and the proxy end establishes a long connection with the server, the method including: The server controls the proxy based on the request instructions from the front end, and sends the response data returned by the proxy to the front end according to the WebSocket protocol; The front end is used to display the video stream from the proxy in real time.

[0060] This method involves deploying an agent at the industrial equipment site and connecting to the equipment. The agent establishes a long-term connection with the server, allowing the front-end to display the agent's video stream in real time. Since the front-end maintains a long-term connection with the server via the WebSocket protocol, real-time visual feedback on the industrial equipment can be provided through the front-end's web browser. Furthermore, the server can control the agent based on the front-end's request commands and send the response data returned by the agent back to the front-end according to the WebSocket protocol. Therefore, the front-end's web browser can serve as a unified console for remote management of the industrial equipment, improving management efficiency.
