Description

Technical Field

[0001] This invention relates to the fields of industrial automation and industrial Internet of Things (IIoT) technology, specifically to a lightweight monitoring system for soil remediation equipment based on protocol conversion. Background Technology

[0002] In the field of industrial automation, real-time data monitoring of industrial equipment such as programmable logic controllers (PLCs) is crucial for ensuring production safety and improving operational efficiency. Traditional monitoring solutions have the following main shortcomings:

[0003] System deployment is complex and costly. Existing solutions typically rely on installing dedicated Supervisory Control and Data Acquisition (SCADA) software or configuration software at the monitoring terminal. This type of dedicated software is not only expensive to purchase, but also cumbersome to install and configure, requires highly skilled operators, and makes the overall system cumbersome.

[0004] Meanwhile, protocol heterogeneity leads to integration difficulties. Industrial equipment from different manufacturers typically uses their own proprietary or specific communication protocols (such as the Siemens S7 protocol). Building a unified monitoring platform that needs to be compatible with multiple brands of equipment often requires the development or integration of multiple dedicated communication drivers, resulting in high system integration complexity, long development cycles, and difficult maintenance.

[0005] Furthermore, access to monitoring data is inflexible. Traditional monitoring systems are typically tied to specific industrial control computers or servers, requiring monitoring personnel to operate from fixed locations, making convenient access anytime, anywhere, and across platforms (such as using personal computers, tablets, or mobile phones) impossible. Achieving remote access usually requires complex network configurations (such as Virtual Private Networks (VPNs), resulting in a poor user experience.

[0006] Intrusiveness and risks coexist. To achieve data acquisition, many solutions require modifying the original control programs of monitored devices such as PLCs and adding dedicated communication function blocks. This intrusive modification may not only affect the stability of the original control logic but also introduce potential security risks. Therefore, the industry urgently needs a monitoring system that is easy to deploy, low-cost, compatible with multiple industrial protocols, and supports remote access via lightweight methods (such as web pages) to solve the problems of poor protocol compatibility, cumbersome system deployment, and inflexible access in industrial monitoring. Summary of the Invention

[0007] To address the problems existing in the prior art, the purpose of this invention is to provide a lightweight monitoring system for soil remediation equipment based on protocol conversion. This system can collect industrial equipment data in a non-invasive manner, achieve multi-protocol conversion through configuration, and ultimately provide a monitoring interface through a general-purpose web browser. It features flexible deployment, low cost, and easy maintenance.

[0008] The technical solution adopted by this invention to solve its technical problem is: a lightweight monitoring system for soil remediation equipment based on protocol conversion, including a protocol conversion gateway, a configuration management module, and a web monitoring terminal.

[0009] The protocol conversion gateway is deployed on an edge computing device that can access the industrial control network, and the protocol conversion gateway has a multi-protocol driver library;

[0010] The configuration management module consists of at least one configuration file, which is used to define the data collection and conversion rules of the protocol conversion gateway;

[0011] The web monitoring terminal is a web application running on an edge computing device or a standalone server.

[0012] Specifically, the protocol conversion gateway establishes data connections with one or more soil remediation devices using different communication protocols by reading configuration files, and periodically collects predefined device data points in read-only mode. Internally, the protocol conversion gateway encapsulates the collected raw data of various formats into a standardized data model, and simultaneously provides at least two standardized data output interfaces: the first interface is a standard industrial communication protocol server; the second interface is a lightweight WebAPI based on HTTP / HTTPS protocol, and there are also extended protocols such as MQTT protocol and IEC 60870-5-104 protocol.

[0013] Specifically, the protocol conversion gateway is an application developed based on the Python language. The protocol conversion gateway uses the open-source Snap7 library to communicate with the PLC and has a built-in ModbusTCP server module and a lightweight HTTP server module.

[0014] Specifically, the configuration file is in text format and includes at least a first configuration file and a second configuration file. The first configuration file is used to define the connection parameters between the protocol conversion gateway and the soil remediation device. The second configuration file is used to define the data points to be collected in tabular form, including the data point name, storage address in the soil remediation device, data type, and read / write attributes. By modifying the configuration file, the monitoring objects and behaviors of the protocol conversion gateway can be adjusted.

[0015] Specifically, the first configuration file is in .ini format and is used to set the network address, communication port, polling cycle, and enabled data service port of the soil remediation equipment.

[0016] Specifically, the second configuration file is in .csv format. Each line of the second configuration file defines an independent data point, which corresponds to specific data in the memory of the soil remediation device by specifying the data block number, starting byte address and data type.

[0017] Specifically, the web monitoring terminal obtains real-time data by accessing the second or first interface provided by the protocol conversion gateway; the web monitoring terminal provides a graphical editing interface, allowing users to construct monitoring screens by dragging and dropping controls, and bind the display or control controls in the screens to specific data points provided by the protocol conversion gateway for the visualization of soil remediation equipment data and parameter settings.

[0018] Specifically, the web monitoring terminal is FUXA, an open-source software running on a Node.js environment, and is accessed and operated through a browser.

[0019] Specifically, the system also includes a data source simulator for simulating soil remediation equipment.

[0020] The present invention has the following beneficial effects:

[0021] This invention presents a lightweight monitoring system for soil remediation equipment based on protocol conversion. This system boasts lightweight deployment and low cost; the monitoring terminal is simply a webpage accessible via a browser, requiring no dedicated client software installation. The core protocol conversion gateway can be deployed on low-cost general-purpose computing devices (such as industrial PCs and mini-PCs), built using an open-source software stack, significantly reducing the system's hardware and software costs. It offers flexible configuration and strong compatibility. Data points are defined through text configuration files, allowing the system to quickly adapt to soil remediation equipment of different brands and protocols, solving the problem of protocol heterogeneity. Adding or modifying monitoring points only requires editing the configuration file and restarting the gateway service, eliminating the need for programming and greatly improving the system's flexibility and maintainability.

[0022] The present invention presents a lightweight monitoring system for soil remediation equipment based on protocol conversion. This system features non-intrusive data acquisition, with the protocol conversion gateway interacting with the soil remediation equipment as a client of a standard communication protocol. It only reads data without writing it into the control logic, without making any modifications to the original production system, thus ensuring the independence and security of production control.

[0023] The lightweight monitoring system for soil remediation equipment based on protocol conversion designed in this invention is easy to access and cross-platform. Users can access the monitoring interface through a web browser on any terminal device (computer, tablet, mobile phone) on a local area network or the Internet, realizing true remote monitoring and maintenance anytime and anywhere.

[0024] This invention presents a lightweight monitoring system for soil remediation equipment based on protocol conversion. It features dual data interfaces for easy integration, providing both Modbus TCP and WebAPI interfaces. The Modbus TCP interface facilitates seamless integration with traditional industrial systems such as SCADA and MES; the WebAPI interface enables data interaction with modern IT systems, cloud platforms, or mobile applications, offering strong scalability.

[0030] The technical solutions of the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] like Figure 1 As shown, an embodiment of a lightweight monitoring system for soil remediation equipment based on protocol conversion includes: soil remediation equipment (such as a PLC, simulated using a Snap7 Server emulator) as the data source, a protocol conversion gateway, configuration management files, and a web-based monitoring terminal.

[0032] 1. System Setup

[0033] On an edge computing device with a Windows / Linux operating system, deploy the following software components in sequence:

[0034] Data source simulator: Run the open-source serverdemo.exe (from the Snap7 toolkit) to simulate a PLC and provide an S7 protocol communication interface.

[0035] Protocol Conversion Gateway: Runs a Python-based gateway program (Snap7Client3.5.4.py). This program depends on the Snap7-Python library, Modbus-TK library, etc.

[0036] Web monitoring terminal: Deploy FUXA, an open-source Web SCADA software based on Node.js.

[0037] 2. Configuration and operation of the protocol conversion gateway

[0038] The behavior of the protocol conversion gateway is controlled by two files in the configuration management module:

[0039] Edit the first configuration file (e.g., config.ini), set the IP address of the soil remediation device (PLC) to 127.0.0.1, and enable the Modbus TCP server port 502 and the Web API server port 5000, as follows. Figure 4 As shown.

[0040] like Figure 2 As shown, edit the second configuration file (e.g., point table.csv) to define the data points to be collected. For example, add a row: Motor Temperature, REAL, 4, 1, Read Only. This configuration indicates that a REAL (floating-point) type data point, named "Motor Temperature", will be read from the DB1 data block of the soil remediation device (PLC) with IP address 127.0.0.1, starting from the 4th byte, and set to read-only permission.

[0041] Start the protocol conversion gateway program. The program will execute as follows: Figure 3 The process is as follows: Parse the configuration file, connect to the PLC through the Snap7 library and read the data at address DB1.DBD0 in a loop; then, map the read floating-point value to the holding register of the ModbusTCP server (such as address 0) and a JSON interface key value of the WebAPI (such as {"motor temperature":75.3}).

[0042] 3. Configuration and access to the web-based monitoring terminal

[0043] The user opens a browser on another computer on the network and enters the address of the FUXA server (such as http: / / 192.168.1.100:1881).

[0044] In FUXA's editing mode, such as Figure 5 As shown, first add a Modbus TCP device (or HTTP data source) pointing to the address of the protocol conversion gateway (192.168.1.100:502 or port 5000 API).

[0045] Create a variable under this device, such as Temp_Motor, and bind its address to address 0 of the Modbus register (or the corresponding JSON key of the WebAPI).

[0046] Save the project and switch to run mode. At this point, the "Numerical Display" control on the webpage will display the "Motor Temperature" value, such as "75.3", read from the DB1.DBD0 address of the soil remediation equipment (PLC) and converted by the gateway. Users can also add input box controls and bind them to writable variables to modify PLC parameters via the webpage.

[0047] 4. Effect Verification

[0048] The operator used clientdemo.exe (the client program in the Snap7 toolkit) to connect to serverdemo.exe and modified the value of the DB1.DBD0 address of the simulated soil remediation device (PLC). It was observed that the values ​​on the FUXA web monitoring interface updated in real time, verifying that the complete data link from the data source -> protocol conversion gateway -> web front-end had been successfully established.

[0049] In summary, this invention, through a three-layer design of protocol conversion gateway, configuration-based management, and web-based terminal, effectively solves the problems of poor protocol compatibility, heavy system deployment, and inflexible access in industrial monitoring, and provides an efficient, economical, and secure lightweight monitoring solution.
