Description

Technical Field

[0001] This utility model belongs to the field of high-speed railway traction power supply technology, specifically relating to a holographic perception system for digital twin operation and maintenance data of high-speed railway traction substations. Background Technology

[0002] Currently, operation and maintenance data for high-speed railway traction substations are mainly acquired through the substation integrated automation subsystem, online monitoring subsystem, and substation auxiliary monitoring subsystem. In the traditional high-speed railway traction substation auxiliary monitoring system, the substation integrated automation subsystem is a core production control system, primarily responsible for real-time data acquisition and control of the operation and maintenance status of primary and secondary equipment. The online monitoring subsystem and the substation auxiliary monitoring subsystem are operation and maintenance support systems. The online monitoring subsystem mainly acquires online status data for the operation and maintenance of primary and secondary equipment, while the substation auxiliary monitoring subsystem mainly acquires operation and maintenance inspection data and performs automatic inspection functions. The online monitoring subsystem and the substation auxiliary monitoring subsystem have the following main problems:

[0003] 1) The online monitoring subsystem and the substation auxiliary monitoring subsystem are both independent subsystems with redundant hardware and software configurations, making data sharing difficult.

[0004] 2) The substation auxiliary monitoring subsystem needs to configure one camera for every 2 to 3 cabinets in the control room and switchgear room to obtain operation and maintenance inspection data, or set up one indoor rail robot in the computer room, and set up high-definition cameras and wheeled robots outdoors. The equipment configuration is complicated, the investment is high, and the indoor and outdoor equipment cannot be shared.

[0005] 3) The cameras, indoor rail robots, and outdoor wheeled robots installed in the substation auxiliary monitoring subsystem are limited by the flexibility of the equipment itself, resulting in blind spots in spatial monitoring, incomplete dimensions of operation and maintenance inspection data acquisition, and inability to achieve holographic perception.

[0006] To address the aforementioned issues in the current support for operation and maintenance data collection in high-speed railway traction substations, a novel holographic perception system for operation and maintenance data of high-speed railway traction substations is designed. This system achieves the integrated hardware and software integration of the online monitoring subsystem and the substation auxiliary monitoring subsystem, while simultaneously realizing data fusion among the substation integrated automation subsystem, online monitoring subsystem, and substation auxiliary monitoring subsystem. This enhances the spatial dimension of substation operation and maintenance inspection data collection, providing a reliable guarantee for the safe operation of the traction power supply system. Utility Model Content

[0007] This invention addresses the shortcomings of existing technologies by providing a holographic perception system for digital twin operation and maintenance data of high-speed railway traction substations.

[0008] This utility model is achieved through the following technical solution:

[0009] A holographic perception system for digital twin operation and maintenance data of high-speed railway traction substations is disclosed, comprising a substation intelligent monitoring and control system. The substation intelligent monitoring and control system is connected to a substation online monitoring subsystem, a substation environmental monitoring and control subsystem, a substation security monitoring subsystem, a substation UAV inspection system, a substation integrated automation system, and a substation intelligent monitoring and control workstation via a substation intelligent monitoring and control switch. A one-way isolation device is installed between the substation integrated automation system and the substation intelligent monitoring and control switch to achieve one-way isolation when transmitting data from the substation integrated automation system to the substation intelligent monitoring and control system. The substation UAV inspection subsystem is connected to the substation intelligent monitoring and control switch via a substation wireless access security gateway. The substation intelligent monitoring and control system processes the data from each connected system and transmits it to the substation intelligent monitoring and control workstation and the railway integrated data network.

[0010] Furthermore, the substation drone inspection subsystem includes a drone and a drone nest, wherein the drone is equipped with an inspection camera and / or an infrared thermal imager.

[0011] Furthermore, the substation online monitoring subsystem includes a transformer monitoring unit, a high-voltage cable monitoring unit, a high-voltage switch monitoring unit, a protection device monitoring unit, and an AC / DC system monitoring unit.

[0012] Furthermore, the substation environmental monitoring and control subsystem includes a substation fire alarm device, a temperature and humidity monitoring device, a wind power monitoring device, a water immersion monitoring device, a water pump monitoring device, a lighting monitoring device, an air conditioning monitoring device, and an electric fire door. The electric fire door is installed in the substation control room, switch cabinet room, and indoor and outdoor passageway doors.

[0013] Furthermore, the substation security monitoring subsystem includes a perimeter intrusion alarm system, a glass breakage alarm system, an infrared detection system, and an access control system.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model provides a holographic perception system for operation and maintenance data supporting digital twins in high-speed railway traction substations. By deploying drones and drone nests within the substation, and wirelessly accessing a security gateway, the system simplifies the configuration of substation inspection equipment. The drones are equipped with inspection cameras and infrared thermal imagers, and the indoor and outdoor partition doors are replaced with electric fire doors. This enables integrated inspection of primary and secondary equipment both indoors and outdoors, as well as temperature monitoring of heat-prone components such as outdoor high-voltage incoming lines, transformers, and feeders. It improves the flexibility of inspections and eliminates blind spots in spatial monitoring. Through the configuration of an intelligent monitoring and control system for the substation, it fully integrates existing hardware such as the substation online monitoring subsystem host, video analysis server, and integrated application server. It also integrates data from the substation drone inspection subsystem, the substation environmental monitoring and control subsystem, the substation security monitoring subsystem, the substation online monitoring subsystem, and the substation integrated automation system. This reduces system investment while achieving data sharing and holographic perception of substation operation and maintenance data. Attached Figure Description

While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

It should be noted that, without conflict, the embodiments and features in the embodiments of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] This utility model addresses the problems existing in current substation online monitoring subsystems and substation auxiliary monitoring subsystems by designing a holographic perception system for operation and maintenance data that supports digital twins of high-speed railway traction substations. Figure 1 As shown, it includes: a substation intelligent monitoring and control system, a substation intelligent monitoring and control workstation, a one-way isolation device, a substation intelligent monitoring and control switch, a substation wireless access security gateway, a substation UAV inspection subsystem, a substation environmental monitoring and control subsystem, a substation security monitoring subsystem, a substation online monitoring subsystem, and a substation integrated automation system.

[0019] The substation intelligent monitoring and control system comprises an interface module, a storage module, and a computing module. The interface module connects to data from various subsystems and the substation's integrated automation system through unified interfaces (communication interfaces, I / O interfaces, etc.). The storage module stores the connected data and the data generated by the computing module. The computing module processes and analyzes the data from the connected subsystems and uploads it to the railway data network. The substation intelligent monitoring and control system utilizes a single set of hardware and software resources to achieve numerous functions, including those of the substation communication management unit, online monitoring subsystem, video analysis server, and integrated application server. This enables intensive resource utilization and data sharing for substation operation and maintenance, while also providing conditions for deploying communication gateways, online monitoring, environmental monitoring and control, security monitoring, and drone inspections—all applications that provide holistic perception of operation and maintenance data.

[0020] The substation intelligent monitoring and control workstation is connected to the substation intelligent monitoring and control system through the substation intelligent monitoring and control switch. It receives the data analyzed and processed by the substation intelligent monitoring and control system to achieve integrated monitoring of real-time status data, online monitoring data, and operation and maintenance inspection data of the substation's primary and secondary equipment, thereby improving operation and maintenance efficiency.

[0021] The substation intelligent monitoring and control switch enables the substation unmanned aerial vehicle inspection subsystem, substation environmental monitoring and control subsystem, substation security monitoring subsystem, substation online monitoring subsystem, and substation integrated automation subsystem to be connected to the substation intelligent monitoring and control system, and realizes the interface with the railway integrated data network.

[0022] The substation wireless access security gateway connects the substation drone inspection subsystem with the substation intelligent monitoring and control switch to enable wireless communication and real-time data transmission between the substation intelligent monitoring and control system.

[0023] The unidirectional isolation device enables unidirectional isolation when transmitting data from the substation's integrated automation system to the substation's intelligent monitoring and control system.

[0024] The substation drone inspection subsystem includes drones, drone housings, inspection cameras, and infrared thermal imagers. The drones, equipped with inspection cameras, monitor the appearance of primary and secondary equipment both indoors and outdoors in the substation, conduct inspections, and assist in emergency command. The infrared thermal imagers monitor the temperature of heat-prone components such as outdoor high-voltage incoming lines, transformers, and feeders. The drone housings handle drone takeoff, landing, charging, maintenance, data processing, and data transmission.

[0025] The substation environmental monitoring and control subsystem includes fire alarm devices, temperature and humidity monitoring devices, wind power monitoring devices, water immersion monitoring devices, water pump monitoring devices, lighting monitoring devices, air conditioning monitoring devices, and electric fire doors. It enables environmental monitoring of the substation, including fire alarms, temperature and humidity, wind power, and water immersion, as well as monitoring of equipment such as fans, water pumps, lighting, air conditioning, and electric fire doors. Electric fire doors are installed in the substation control room, switchgear room, and indoor / outdoor passageways. Drones intelligently determine the opening status of electric fire doors and allow passage based on inspection time, inspection route, and onboard LiDAR and inspection cameras. This achieves integrated inspection of primary and secondary equipment both indoors and outdoors, and enables shared use of indoor and outdoor drones, enhancing the dimension and breadth of operational data perception.

[0026] The substation security monitoring subsystem includes a perimeter intrusion alarm system, a glass breakage alarm system, an infrared detection system, and an access control system, realizing security and monitoring functions such as perimeter intrusion, access control, and video surveillance.

[0027] The substation online monitoring subsystem includes a transformer monitoring unit, a high-voltage cable monitoring unit, a high-voltage switch monitoring unit, a protection device monitoring unit, and an AC / DC system monitoring unit. It realizes the acquisition of status monitoring data of primary and secondary equipment in the substation, including online status data acquisition of high-voltage switches, transformers, high-voltage cables, protection devices, AC systems, and DC systems.

[0028] The substation environmental monitoring and control subsystem is responsible for collecting environmental monitoring data such as fire, temperature and humidity, wind force, and water immersion in the substation. The substation security monitoring subsystem is responsible for collecting security monitoring data such as perimeter intrusion, access control, and video surveillance in the substation. The substation online monitoring subsystem is responsible for collecting status monitoring data of primary and secondary equipment in the substation. The monitoring data of the relevant subsystems are connected to the substation intelligent monitoring and control system through the substation intelligent monitoring and control switch.

[0029] The substation integrated automation subsystem is responsible for collecting various analog, switch, and digital status data of primary and secondary equipment in the substation and for equipment monitoring. It connects the relevant monitoring data to the substation intelligent monitoring and control system through a one-way isolation device and the substation intelligent monitoring and control switch.

[0030] The substation drone inspection subsystem collects multi-dimensional status data integrating air and ground, such as the appearance of indoor and outdoor primary and secondary equipment and temperature monitoring of easily heated parts, through linkage with electric fire doors. It also uses drone nests for take-off, landing, charging, and maintenance, and connects the relevant monitoring data to the substation intelligent monitoring and control system through the drone nest wired network, the substation wireless access security gateway, and the substation intelligent monitoring and control switch.

[0031] After the substation intelligent monitoring and control system accesses data from various related systems, it performs unified calculation, storage, analysis and processing, and deploys holistic perception applications for operation and maintenance data such as communication gateways, online monitoring, environmental monitoring and control, security monitoring, and drone inspections. This enables the intensive utilization of resources and the sharing, intelligent analysis and processing of substation operation and maintenance data. Finally, it provides integrated monitoring and display through the substation intelligent monitoring and control workstation, thereby improving operation and maintenance efficiency.
