Description

Technical Field

[0001] The present invention relates to the technical field of near-electrical operations, and in particular to a near-electrical operations safety monitoring and early warning system based on digital twins. Background Art

[0002] During the construction of power projects, due to the complex working environment and harsh working conditions, as well as the possible negligence or misjudgment of operators, there are high safety risks, especially the risk of electric shock accidents. In order to reduce the occurrence of such accidents and improve the safety of operations, researchers began to explore how to use modern technical means to assist safety management. As a result, a safety monitoring and early warning system for near-electric operations that combines intelligent image processing technology and wireless communication technology came into being. These systems can monitor the distance between operators and live equipment in real time. Once they are close to the dangerous range, the system will sound an alarm to remind operators to take timely measures to avoid electric shock accidents.

[0003] For example, the existing Chinese patent (CN106559653B Near-electricity Operation Safety Monitoring and Early Warning System) discloses a Near-electricity Operation Safety Monitoring and Early Warning System, which is based on the initial image and the various safety distances specified for power construction, and sets an early warning area, that is, a monitoring area. Once an object enters the monitoring area, the system can identify and alarm; the data processing and analysis system should be located in a safe position outside the operation area. The advantages are that it can adapt to most natural environments, is simple to deploy, has a wide range of applications, and achieves a fully effective monitoring effect within a safe range. Based on a stable data source and reliable data analysis, the present invention achieves a stable and reliable monitoring effect to ensure safe construction.

[0004] However, existing safety monitoring and early warning systems for near-electrical operations often rely on fixed rules and thresholds to trigger alarms, lack the ability to conduct in-depth analysis of big data, cannot fully utilize the collected information for more complex predictions and diagnoses, and have slow response speeds. In addition, the alarm mechanism of traditional systems is usually based on a simple comparison of real-time data streams, which cannot achieve predictive maintenance and immediate response, and may result in problems being discovered and measures being taken only after they occur.

[0025] See also Figure 1 The present invention provides a technical solution: a near-electric operation safety monitoring and early warning system based on digital twins, comprising: a platform layer 100, an application layer 200 and a service layer 300, the platform layer 100 comprises: digital twin applications 101, safe production management and control 102, substation production scheduling 103 and station-side service applications 104; the application layer 200 comprises: simulation processing 201, interface management 202, alarm center 203, process management 204, data center 205, monitoring center 206, scene linkage 207 and information security 208; the service layer 300 comprises: power outage status visualization 301, safe area supervision 302 and scene twin interaction 303.

[0026] Digital twin application 101 uses sensor data, historical data and other relevant information to build and manage virtual models of power equipment and its operating environment in virtual space, realizing digital mapping of physical entities. It provides a dynamic, high-fidelity virtual environment that enables users to monitor and simulate the status of power equipment in real time. In the power industry, digital twin applications can be used to monitor the operating status of facilities such as power plants and substations, helping operation and maintenance personnel to detect potential problems in a timely manner and improve the reliability and stability of the power grid. For example, it can be used to predict the wear of equipment and arrange maintenance in advance; or in the event of a failure, find the most effective repair method through simulation to reduce power outage time.

[0027] Production safety control 102 is used to manage the production activities of the entire power system, including: work planning, personnel allocation, equipment inspection, to ensure that production activities comply with safety regulations, reduce the possibility of accidents, and improve production efficiency. Substation production scheduling 103 is used to coordinate the operation and maintenance of various equipment in the substation to ensure stable and reliable power supply. Optimize resource allocation, improve substation operation efficiency, and ensure the continuity and reliability of the power grid.

[0028] The station-side service application 104 is used to provide necessary service support for substation staff, including information query and task allocation, simplify daily work processes, and improve work efficiency and service quality within the station.

[0029] Simulation processing 201 uses digital twin models for simulation to predict device behavior and system response, help identify potential problem points, optimize operation strategies, and improve fault prevention capabilities. Interface management 202 is used to manage communication protocols and data exchanges between different components to ensure seamless collaboration between modules. Alarm center 203 is used to centrally manage all warning information and trigger corresponding alarms according to preset rules.

[0030] Process management 204 is used to define and manage business processes related to power operations, standardize operating procedures, reduce human errors, and improve the transparency and controllability of process execution. Data center 205 is used to store and manage all historical and real-time data related to the system. Monitoring center 206 is used to display indicators of power equipment and environment in real time. Scenario linkage 207 triggers linkage responses between multiple modules according to preset conditions. Information security 208 is used to ensure the network security of the system and prevent unauthorized access and data leakage.

[0031] The power outage status visualization 301 is used to provide a visual display of the power outage area to help quickly locate the problem area. The safety area supervision 302 is used to monitor the safety situation in the operating area in real time. The scene twin interaction 303 is used for users to interact with the digital twin environment and simulate different operating scenarios.

[0032] When constructing the model, Digital Twin Application 101 builds a digital model that corresponds one-to-one to the actual substation based on the collected design drawings, simulation results, and actual operation data, and simulates the flow of power in the digital twin model to ensure that the model can correctly reflect the interaction between power equipment.

[0033] Equipment parameter collection and real-time modeling are one of the important steps in building a digital twin. CAD software or other design tools are used to draw a design blueprint of the substation, including information such as the location, size, and connection method of the equipment. Design tools can help engineers accurately plan the equipment layout and ensure that the design meets actual needs and technical specifications. Use simulation software to simulate the designed substation to verify whether it can work normally under different load conditions. Deploy various sensors (such as temperature sensors, current transformers, voltage transformers, etc.) in the substation to collect data on the operating status of the equipment in real time.

[0034] The digital twin model constructed by Digital Twin Application 101 includes: site name, interval name, line name, relative position, power relationship identification, and displays the power connection relationship between each device, allowing users to intuitively see the direction and status of power flow.

[0035] The alarm center 203 also includes: detection area division: according to the different voltage levels of the power line, determine the specific area and range to be monitored, laser radar detection, high-definition video images, multi-point mobile deployment and safety alarm and linkage. The safety distance requirements under different voltage levels are different, so it is necessary to determine the boundaries of the monitoring area according to national or industry safety standards. The high-definition camera is used to capture the visual information of the work site, and the movement of personnel and the movement trajectory of mechanical equipment are identified through video analysis technology. The laser radar can provide high-precision distance measurement and is suitable for detecting the position of large machinery and personnel relative to live equipment. The laser radar and high-definition video device can be deployed at multiple key locations to cover the perimeter of the entire live area. The multi-point deployment can ensure monitoring without blind spots and improve the reliability and accuracy of the system. When the laser radar or high-definition camera detects that a person or machine enters the set safety distance range, the system will automatically trigger an intrusion detection alarm. The alarm information can be transmitted to the on-site operators through sound, light or other forms of notification. Once a potential security threat is detected, the system immediately activates the on-site sound and light alarm device to attract the attention of the operator. The linkage mechanism can quickly remind operators to take corresponding protective measures to avoid safety accidents.

[0036] The present invention uses digital twin technology to build a digital twin that matches the real scene for the important lines and points in each compartment of the substation. Based on the energized relationship between the lines, it truly displays the power outage status of the lines in each compartment during the substation's safe production operations, constantly monitors the intrusion of foreign objects within a safe distance around the energized lines, improves the level of on-site safety supervision, and provides auxiliary decision-making for remote command of substation safety production management and control operations and hidden danger detection.

[0037] It can provide very detailed simulations, including the working status of power equipment, environmental conditions, and potential safety hazards, which makes the understanding of the on-site situation more accurate; through real-time data streaming, digital twins can instantly update the status of virtual models, and predict future trends based on historical data and current conditions, and identify possible safety threats in advance. Simulation training and emergency drills can be conducted in a digital twin environment to improve the operating skills of staff and their ability to respond to emergencies. Digital twins can also help maintenance teams better plan maintenance work, optimize the operating efficiency of equipment, and extend its service life. By detecting potential problems early and taking preventive measures, unexpected downtime and maintenance costs can be reduced, and overall operational efficiency can be improved.
