[0018] Figure 2It is a structural principle diagram of the computer virtual simulation system of the present invention. DETAILED DESCRIPTION

[0019] like Figure 1-2 As shown, a distribution network operation and inspection virtual simulation training system of the present invention comprises an operation platform 1, a computer virtual simulation system and a 3D helmet display device 5, wherein the computer virtual simulation system is installed inside the operation platform 1, and a shading shield 11 is provided on the left and right sides of the operation platform 1, and a back plate 12 is provided on the front side of the operation platform 1, and a foot control device 2 is provided at the bottom of the operation platform 1, and the foot control device 2 is used to start and pause the evolution of the simulated visual picture of the computer virtual simulation system, and a three-dimensional mouse 3 and a force feedback operation device 4 are provided on the table of the operation platform 1, and the three-dimensional mouse 3 is used to simulate the perspective change of the visual picture, and the force feedback operation device 4 can realize the precise angle simulation picture of the inspection tool operation under the action of the 3D helmet positioning system 6. A double-layer curtain device 61 is installed on the back plate 12, and the 3D helmet display device 5 is provided with a 3D helmet positioning system 6 for information interaction with the double-layer curtain device 61, and the 3D helmet display device 5 is used for the wearer to observe the interactive simulation scene picture generated by the computer virtual simulation system.

[0020] Specifically, an antenna pole is set up on the top of the 3D helmet display device 5, and a laser emission module is fixedly installed on the top of the antenna pole. A spot detection camera 62 for detecting the position of the laser spot on the curtain is provided at the rear of the double-layer curtain device 61, and a posture gyroscope is fixedly installed on the 3D helmet display device 5. The laser emission module includes three groups of laser emitters, and the three straight lines where the light beam emission directions of the three groups of laser emitters are located are not coplanar and intersect at one point in space. The three pairs of six light spot positions generated by the laser emission module on the double-layer curtain device 61 are determined by the light spot detection camera 62 by determining the spatial position of each pair of light spots. The three groups of light spots determine three non-coplanar straight lines in space. A spatial point position that remains relatively still with the helmet is calculated by the computer system, and then the relative posture position data of the helmet is calculated by the relative position through the posture data of the gyroscope, so that the computer virtual simulation system can project the corresponding virtual operation scene screen according to the relative posture position data of the helmet, so as to achieve the simulation reproduction of the operation training action in the virtual space, and improve the real immersion of the training process. In addition, a function can be set to start a trigger program in the helmet position calibration of the computer, so that when the operator's helmet moves to the designated space area in front of the operating platform 1, the force feedback precise operation virtual simulation scene reproduction program is triggered, thereby reducing the difficulty of calculating and processing a large amount of force feedback space data and improving the generation quality of the virtual simulation scene picture.

[0021] The computer virtual simulation system includes a system login module, an operation and inspection scenario selection module and an operation control simulation module, and the system login module includes a role selection module and a team empowerment function module. In the actual production management practice of power distribution, the distribution network is usually operated and inspected in teams to improve the level of distribution network operation and maintenance and ensure the safe and economic operation of the distribution network. It includes team leaders, technicians, live operation team members and other personnel, because the knowledge and experience requirements for different work requirements are different. Through the role selection module, you can choose to create different operating roles, and at the same time, you can set the permissions of the designated inspection and repair team members through the team empowerment function module.

[0022] The operation and maintenance scenario selection module includes an operation project scenario, a daily inspection scenario and an emergency repair scenario. The operation project scenario includes a training scenario sub-mode. The daily inspection scenario includes a training scenario sub-mode and an assessment scenario sub-mode. The emergency repair scenario includes an assessment scenario sub-mode. The operation project scenario includes an insulation status inspection scenario, a mechanical status inspection scenario unit, a measurement and test scenario unit, a cleaning and maintenance scenario unit, a lubrication and maintenance scenario unit, a fastening inspection scenario unit and a replacement and repair scenario unit. The daily inspection scenario includes a continuous scenario that is pre-retrieved through a single scene in the operation project scenario and arranged in a certain time sequence. The emergency repair scenario includes a preset troubleshooting step unit, a measure taking step unit and a record reporting step unit.

[0023] The training scenario sub-modes are all implanted with a training prompt function unit, which includes an electrical information index function unit and an error correction prompt box function unit. The electrical information index function unit is linked to an expert database module. The training prompt function unit is used to provide error correction prompts for simulated operations in the training scenario sub-mode in the work project scene and daily inspection scene. The above-mentioned assessment scenario sub-modes are all implanted with an assessment recording unit. The assessment recording unit includes an error correction animation generation module, which is used to record erroneous actions and generate error correction animation data and play them back. The assessment recording unit is linked to an assessment analysis module, which is used to generate a comprehensive score, evaluation and analysis of the corresponding team and provide standardized recommendations for the next stage.

[0024] In actual operation, the computer virtual simulation system pre-stores the above-mentioned designated scene screen data and sets the corresponding function program. The operator first wears the 3D helmet display device 5, the operator directly obtains the visual image, and enters the system login module through the 3D mouse 3 to control the selection of the corresponding training or assessment role, and then selects the corresponding scene to achieve the training under the scene. For example, select the daily inspection scene and the training scene sub-mode at the same time. In this mode, the operator inspects according to the scene animation in the preset time sequence, controls the time evolution of the animation through the foot control device 2, and releases the foot control device 2 when reaching the designated position, and inspects the designated position. For example, when it is necessary to check the mechanical status of the equipment in the virtual screen, the head moves forward so that the helmet enters the designated area, triggering the force feedback precise operation virtual simulation scene reproduction, and the helmet worn by the operator will reproduce the actual maintenance action of the force feedback operation device 4 in real time, and in this mode, important inspection points can be prompted through the training prompt unit for learning, and after completing the inspection of the designated position, exit and continue the maintenance until the entire daily inspection scene is completed. Through the above training, operators can systematically train and learn various work items in daily inspection scenarios, thereby improving their operating skills and accumulating experience in handling various work project scenarios.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
