Description

Technical Field

[0001] This invention relates to the field of switchgear maintenance technology, specifically a switchgear maintenance system based on virtual reality technology. Background Technology

[0002] A switchgear is an electrical device. External lines first enter the main control switch inside the switchgear, and then enter the branch control switches. Each branch is set according to its needs, such as instruments, automatic control, motor magnetic switches, various AC contactors, etc. Some also have high-voltage and low-voltage switchgear, and have high-voltage busbars, such as power plants. Some also have low-frequency load shearing to protect the main equipment. The main function of switchgear is to open, close, control and protect electrical equipment in the process of power generation, transmission, distribution and power conversion in the power system.

[0003] However, the current maintenance workload of switchgear is large and the inspection efficiency is low. Therefore, it is necessary to use virtual reality technology to analyze and simulate the internal and external conditions of switchgear, determine the location of damage, and improve the maintenance efficiency of switchgear. Summary of the Invention

[0004] This invention provides a switchgear maintenance system based on virtual reality technology, which can effectively solve the problems of large workload and low inspection efficiency in the current switchgear maintenance mentioned in the background.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a switchgear maintenance system based on virtual reality technology, comprising a main control module, a virtual construction module, an external detection module, a device detection module, a path detection module, a terminal detection module, and a virtual maintenance module;

[0006] The main control module controls the operation of other modules;

[0007] The virtual construction module collects real-world data of the switchgear, builds a virtual model, and monitors and supplements the real-world data in real time, including a real-world data collection unit, a real-world construction unit, and a real-time supplementation unit.

[0008] The external detection module detects the exterior of the switch cabinet, including an outer casing detection unit and a surrounding environment detection unit.

[0009] The device testing module performs individual testing on the electrical components inside the switch cabinet, including a functional testing unit and a physical testing unit;

[0010] The path detection module detects the paths between devices, including a sorting unit and a path detection unit;

[0011] The terminal detection module detects the connection terminals and grounding wires, and includes a terminal detection unit and a grounding detection unit.

[0012] The virtual maintenance module performs virtual use of the switchgear, virtualizes the damage status of components and physical parts, detects situations that exacerbate wear and tear, and performs virtual maintenance.

[0013] According to the above technical solution, the real-scene acquisition unit in the virtual construction module acquires real-scene data of the switch cabinet, including the external structural dimensions, external images, internal images, internal structural dimensions, internal component images and positions of the switch cabinet;

[0014] The virtual construction module's real-scene construction unit builds a scaled-down virtual switch cabinet model based on the data collected by the real-scene acquisition unit.

[0015] The real-time supplement unit of the virtual construction module supplements the changes in the real scene in a timely manner based on the data collected by the real scene acquisition unit.

[0016] According to the above technical solution, the real-scene acquisition unit collects complete real-scene data every 24-48 hours, and the real-time supplementation unit compares the collected data with the previous data and supplements the changed data.

[0017] The system records and analyzes the changing data, predicts the data changes for the next 24-48 hours, and uses the next collected data to detect the predicted changes.

[0018] According to the above technical solution, the outer casing detection unit of the external detection module inspects the cracks, damage, detachment and contamination of the external cabinet of the virtual switch cabinet;

[0019] The surrounding environment detection unit of the external detection module detects the temperature, humidity, debris, and water leakage around the switch cabinet;

[0020] The input terminal of the external detection module is connected to a temperature and humidity sensor, a water leakage sensor, and a partial discharge sensor.

[0021] According to the above technical solution, the functional detection unit of the device detection module collects the input and output data of electronic components and detects the functions of electronic components in sequence;

[0022] The physical inspection unit of the device inspection module examines the physical images of electronic components and checks for debris, dust, and corrosion on the exterior of the electronic components.

[0023] According to the above technical solution, the sorting unit of the path detection module first sorts out the connection between electronic components to determine the path status;

[0024] During the path routing process, first identify the overall input and output ports of the switchgear, input data through the input ports, and then trace the transmission path along the data transmission route.

[0025] After the transmission path is sorted out, it is then decomposed into several transmission areas.

[0026] According to the above technical solution, the path detection unit monitors the electronic components and wires in the path of the switch cabinet in real time and updates the virtual switch cabinet model data in real time. When detecting the transmission status of the path, virtual data is input from the input port to detect the data reception status of the path. When reception is blocked, the transmission detection is performed on the decomposed transmission area in sequence to find the transmission obstruction area.

[0027] According to the above technical solution, the terminal detection unit of the terminal detection module collects the connection images and data transmission status of all wiring terminals in the switch cabinet. First, it judges the functional status of the wiring terminals based on the data transmission status. When the transmission is blocked, it checks the connection images of the wiring terminals and the changes in the images of the wiring terminals to determine the damage status of the wiring terminals. The wiring terminals with abnormalities are marked, then reinforced, and tested again until the transmission of the wiring terminals returns to normal.

[0028] According to the above technical solution, the grounding detection unit of the terminal detection module collects the cable image of the grounding wire, analyzes and judges the corrosion of the grounding wire, compares the position of the grounding wire joint, and eliminates the possibility of looseness at the joint.

[0029] According to the above technical solution, the virtual maintenance module analyzes the potential data of damaged switchgear based on the virtual switchgear model and the collected external data. In the virtual switchgear model, it predicts the impact of the potential data, analyzes the type and duration of the resulting faults, and provides a reference for maintenance.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] 1. By setting up a real-scene acquisition unit to collect real-scene images of the switchgear, a virtual switchgear model is built using virtual reality technology, and the data of the switchgear is supplemented and updated at a set time. This allows for real-time understanding of the external condition of the switchgear, enabling quick assessment of its status and helping maintenance personnel to conduct a preliminary inspection of the switchgear's exterior.

[0032] 2. By setting up an external detection unit, the switch cabinet's external surface can be inspected for cracks, damage, peeling, and contamination. The surrounding environment detection unit can also detect the temperature, humidity, debris, and water leakage around the switch cabinet. This allows for external inspection of the switch cabinet and identification of locations that may require maintenance based on the external conditions, thus saving subsequent maintenance time.

[0033] 3. By setting up a functional testing unit to acquire input and output data of electronic components, the functional effects of electronic components are tested. The external condition of electronic components is inspected through a physical testing unit, allowing for individual inspection of electronic components. Finally, the circuits of the switch cabinet are sorted and inspected, thus comprehensively inspecting the internal structure of the switch cabinet. Any abnormalities detected are repaired, resulting in higher repair efficiency.

[0034] 4. By setting up a terminal detection unit to test the wiring terminals and a grounding detection unit to test the grounding terminals, loose positions are reinforced to ensure stable wiring, avoid short circuits and poor contact, and ensure the safe use of the switchgear.

[0035] 5. By virtually using the switchgear, the potential damage to the switchgear can be simulated, thereby enabling the understanding of future damage at different locations within the switchgear. Based on the simulation, the location and timing of potential damage can be determined, allowing for the allocation of maintenance locations and times, thus making maintenance more efficient.

[0036] In summary, by building a virtual switchgear using virtual reality technology, the external structure of the switchgear is first inspected to identify the location of damage, continuously narrowing down the repair area. Then, the internal electrical components, circuits, wiring terminals, and grounding terminals are tested, making the internal inspection orderly and efficient. Ideally, the switchgear is then used virtually to simulate damage conditions, allowing people to identify the repair-needing locations from the virtual switchgear inspection and predict potential future damage. This provides a more comprehensive understanding of repair information and assists in the repair process. Attached Figure Description
