[0036] To illustrate the technical solutions of the invention in more detail, specific embodiments are listed below to demonstrate the technical effects; it should be emphasized that these embodiments are used to illustrate the invention and are not intended to limit the scope of the invention.

[0037] The production facility monitoring data and digital twin model integration system provided by this invention, such as... Figure 1 As shown, it includes a production facility monitoring data acquisition device 10, a digital twin association configuration terminal 20, a digital twin display and application terminal 40, and a server 30, specifically:

[0038] The production facility monitoring data acquisition device 10 is used to collect data from various sensors in and around the production facility and encode the data into corresponding strings. The strings contain at least the equipment number corresponding to the production facility and the readings of each sensor.

[0039] The digital twin association configuration terminal 20 is used to parse the equipment number corresponding to the production facility and generate production facility registration information when it comes into contact with the production facility monitoring data acquisition device 10. The production facility registration information includes the basic information of the production facility, the location information, and the configuration information of the sensor.

[0040] The server 30 is used to connect to the production facility monitoring data acquisition device 10 and the digital twin association configuration terminal 20, and to receive the string and the production facility registration information.

[0041] The digital twin display and application terminal 40 is connected to the server 30 by a signal and is used to query the registration information of the production facility and display the dynamic monitoring data of the production facility.

[0042] This invention enables high-precision matching of dynamic data sources to digital twin models of rural production facilities through simple and rapid configuration, providing a data foundation for subsequent monitoring, analysis, and early warning of rural production facilities based on digital twins. This invention simplifies the process of integrating production facility monitoring data into the digital twin model, reducing the workload by 80% and lowering the operational threshold by simplifying technical tasks such as location calibration and data docking into a simple graphical configuration process. The location matching accuracy of this invention can reach sub-meter level, meeting the quality requirements of dynamic data integration for digital twins of production facilities. Furthermore, it can be implemented using widely available smartphones, offering high cost-effectiveness.

[0043] In some embodiments, the production facility monitoring data acquisition device 10 is a customized IoT data acquisition hardware, specifically including a data acquisition module, a data processing module, a data upload module, and an NFC tag module. The data acquisition module is used to query data from each of the sensors, for example, periodically querying data from each sensor from the host of an existing monitoring system via the MODBUS-RTU protocol. The data processing module is used to parse the data acquired by the data acquisition module and encode it into a JSON string containing the device number, channel number, timestamp, and sensor reading. The data upload module is used to upload the string to the server 30, for example, uploading the processed data to the server 30 via a 4G network in the form of an MQTT stream. The NFC tag module is used to write the device number into an NFC tag, for example, encoding the device number into the configuration page URL and writing it to the NFC tag in NDEF format. The digital twin associated configuration terminal 20 can obtain the device number from this NFC tag.

[0044] In some embodiments, the production facility monitoring data acquisition device 10 has a set of RS-485 input interfaces, which traverse the sensor readings of 32 channels at 1-second intervals. After encoding the sensor readings, device number, sensor channel number, timestamp, and other data into JSON format, it is sent to a designated topic on the MQTT Broker on the public internet via a 4G network. The production facility monitoring data acquisition device 10 has an NFC tag, and the configuration page URL containing the device number parameter is pre-encoded in NDEF format and written into the NFC tag.

[0045] In some embodiments, the digital twin association configuration terminal 20 is a handheld smart terminal running specific software and equipped with NFC and GPS functions, typically a villager's Android or iOS operating system smartphone. This terminal runs "digital twin association configuration software," which has the following functional modules: an NFC device number reading module, a GPS positioning and coordinate conversion module, a production facility basic information input module, a sensor configuration module, and a production facility registration information submission module. The NFC device number reading module is used to scan the NFC tag in NDEF format and parse the device number therein. The GPS positioning and coordinate conversion module is used to obtain the positioning information of the production facility, for example, obtaining the position in the WGS84 coordinate system through GPS (Global Positioning System) and converting it to coordinates in the digital twin local coordinate system. The production facility basic information input module is used to provide a first graphical user interface, such as... Figure 4 As shown, the interface allows users to input basic information about the production facility. In some embodiments, users can input basic information such as the name and type of the production facility through this interface. The sensor configuration module provides a second graphical user interface, through which users can preview the readings of the connected sensors and set the configuration information of each sensor, such as setting the sensor type. The production facility registration information submission module is used to submit the production facility registration information to the server 30.

[0046] In some embodiments, a villager's smartphone can be used as a digital twin association configuration terminal 20. This device supports background scanning of NFC tags in NDEF format. When the NFC tag of the production facility monitoring data acquisition device 10 is read, it will automatically open a browser and redirect to a web browser. Figure 4 The configuration page shown. Device identification information is obtained from the URL parameters of the NFC tag, and the production facility's location information is obtained from the phone's GPS. A form is provided on the interface for the user to input basic production facility information and sensor configuration information. After the user clicks submit, the above information is processed and combined into production facility registration information, which is then submitted to the server.

[0047] In some embodiments, the server 30 includes a dynamic data access module and a production facility registration module. The dynamic data access module receives data streams from multiple production facility monitoring data acquisition devices and provides a query interface. The production facility registration module receives the production facility registration information and provides interfaces for adding, modifying, deleting, and querying the basic information, location information, and sensor configuration information of the production facilities. In some embodiments, the server 30 builds a real-time data warehouse system based on Flink, Kafka, and ClickHouse to provide dynamic data access and query services, supporting the use of MQTT streams to receive production facility monitoring data. A Web API interface is provided for production facility registration information and digital twin model data.
