[0023] like Figure 1 As shown, the present invention provides a railway information room monitoring system based on digital twin, comprising: The data acquisition module 100 is used to collect the operation data of the monitored computer room.

[0024] Furthermore, the data acquisition module is responsible for deploying various basic information sensors in the computer room, such as temperature and humidity sensors, smoke detectors, infrared sensors, battery monitoring equipment, etc., to collect the power and environmental parameters of the computer room in real time, and transmit the collected data to the relay unit through optical fiber transmission technology to construct data packets, and then transmit the data packets to the system's data center or cloud platform to ensure the real-time and accuracy of the data.

[0033] The virtual model includes the layout of the computer room, the appearance of the equipment, and the direction of the pipelines.

[0034] Furthermore, the model building module is to express the apparent characteristics of the physical structure of the information room through geometric features. For the room scene with limited internal information of the scene, 3D modeling software is directly used for accurate modeling, including the layout of the room, the appearance of the equipment, the direction of the pipeline, etc., that is, the model-driven digital twin described in the present invention. BIM technology can use digital information technology to create a virtual three-dimensional building model on the computer system, and add an independent, complete, and logical design database to the building module. The specific model design can be simply adjusted and improved based on the reference actual model. In the modeling of the room scene, polygonal modeling methods are usually used to create complex and detailed virtual models of rooms and equipment. The three-dimensional model is effectively mapped and integrated with the multi-dimensional data collected in real time and the virtual model, so the subsequent present invention realizes the real-time transmission of data through IoT technology, and uses methods such as binding data and models to each other, designing and developing virtual-real interaction interfaces, to realize the virtual-real interaction of the actual operating status of the room equipment and the basic key performance indicators of power and environmental parameters.

[0038] The modeling unit uses BIM (Building Information Modeling) technology to establish a virtual model of the monitored computer room. The virtual model is a digital representation of the computer room. The data unit is connected to the modeling unit. The data unit focuses on data collection and reception. The mapping unit is connected to the modeling unit and the data unit respectively. Its function is to map the operating data and equipment status data obtained by the data unit to the virtual model established by the modeling unit. Through mapping, the virtual model not only includes the structure and equipment layout of the computer room, but also includes real-time operating data and equipment status, thus forming a complete digital twin model.

Finally, it is presented on the monitoring system client in the form of a visual 3D scene to provide an intuitive and highly interactive user experience.

[0042] like Figure 4 As shown, the monitoring and analysis module 300 includes: The environment monitoring unit 310 is used to visually monitor the environmental parameters of the monitored computer room.

[0043] The equipment monitoring unit 320 is used to visually monitor the equipment status data of the monitored computer room.

[0045] The roaming unit 340 is used to load the engine of the virtual model and support the user to roam the virtual model through the interactive entry unit 330.

[0046] Furthermore, the environmental monitoring function is to display the temperature and humidity, sound and light, power and other environmental parameters in the computer room through the data collected in real time by multi-dimensional sensors deployed in the physical computer room, so as to ensure that the overall operating status and environment of the computer room meet the basic requirements of operation. The equipment monitoring is to display the virtual twin model of the information computer room in the form of a 3D model. The operation and maintenance personnel can intuitively view the operating status, energy consumption, server performance indicators, sensor-related alarms and other information of each device in the computer room scene, which is convenient for the operation and maintenance personnel to quickly discover problems and locate problematic equipment. In addition, the present invention also provides a roaming unit, which can support first-person roaming in the virtual scene through real-time simulation by loading the engine of the virtual model, so as to facilitate the inspection of the details of the equipment and facilities in the computer room.

[0050] The data center to which the data storage module 500 is connected is a cloud data center.

[0051] Furthermore, compared with traditional monitoring equipment, since digital twins pay more attention to multi-dimensional related data throughout the entire life cycle of the equipment, the present invention provides a series of basic services, such as data storage, data processing, data analysis, etc. By building a distributed database and a big data processing platform, the storage and management of massive data can be achieved, and the data can be deeply mined and analyzed to extract valuable information.

[0054] The present invention provides a railway information room monitoring system based on digital twins, which provides an intelligent monitoring system using digital twin technology. It can monitor the operating status of the equipment in the room in real time, and predict the remaining life and potential failure risks of the equipment through data analysis, so as to carry out maintenance and replacement of related equipment in advance. It can not only effectively reduce the equipment failure rate and improve the reliability and utilization efficiency of the equipment, but also reduce the operation interruption and safety hazards caused by the failure of the information room equipment, thereby effectively reducing the operating costs of the railway lines.

[0055] In addition, the twin model built based on massive data and data mining engines has powerful real-time analysis capabilities, allowing management departments to make more scientific and effective decisions. For example, under harsh environmental conditions, the overall line can be ensured to be safe and stable by strengthening equipment deployment monitoring and preventive maintenance.
