Description

Technical Field

[0001] The present invention belongs to the field of photovoltaic power station operation and maintenance, and specifically refers to a virtual simulation guidance system for photovoltaic power station maintenance. Background Art

[0002] With the popularization of solar photovoltaic power generation systems, the demand for photovoltaic power station maintenance personnel is growing. However, traditional training methods are difficult to provide opportunities for actual operation, resulting in a disconnect between theoretical knowledge and practice. In addition, on-site practical operations are risky and costly, which limits the effectiveness and frequency of training. In recent years, virtual reality (VR), augmented reality (AR) and digital twin technologies have gradually been applied to industrial training, but the application of these technologies in the field of photovoltaic power station maintenance is still immature and lacks targeted solutions.

[0003] At present, PV power station maintenance training mainly relies on the following methods: physical drills: operational training through real PV power station facilities. This method can provide the closest experience to actual combat, but it is costly and has safety hazards; textbook learning: theoretical learning using paper textbooks or electronic documents. Although it can cover a wide range of theoretical knowledge, it lacks practical operation experience. Summary of the invention

[0004] The present invention solves the following technical problems: It provides a highly simulated virtual simulation guidance system for photovoltaic power station maintenance, which can simulate various fault conditions at low cost and low risk, and improve the trainees' practical operation ability and fault handling ability.

[0005] To solve the above problems, the technical solution adopted by the present invention is as follows: the virtual simulation guidance system for photovoltaic power station maintenance proposed in the present invention includes a virtual three-dimensional VR simulation and voice guidance system, the virtual three-dimensional VR simulation and voice guidance system includes a hardware platform and a software platform, the hardware platform includes a simulation workstation, a remote networking collaboration function module and an integrated voice recognition processing technology module, the remote networking collaboration function module includes a wireless transmission device, the integrated voice recognition processing technology module includes a voice receiving device, the simulation workstation is provided with a simulation display interface and a VR head display device, the simulation display interface and the VR head display device are displayed synchronously, the software platform is installed in the simulation workstation, the software platform also includes a typical fault and scheduled inspection project library, a simulation parts library, a simulation tool library, a parts recognition prompt entry library, a fault handling process prompt entry library, a training record and evaluation system, a wireless transceiver software and a voice input analysis software, the software platform is displayed in the simulation display interface and the VR head display device, and the typical fault and scheduled inspection project library is used to find matching faults and scheduled inspection items to be simulated.

[0006] Furthermore, the typical fault and scheduled inspection project library contains no less than 20 typical fault handling tasks and no less than 40 scheduled inspection tasks, which include typical faults and scheduled inspection events of photovoltaic power station components.

[0007] Furthermore, the wireless transmission device and the wireless transceiver software in the software platform are connected in the form of electrical signals, and are used to remotely call out the corresponding local fault operation scene displayed in the simulation display interface and the VR head display device.

[0008] Furthermore, the voice receiving device is electrically connected to the voice input and analysis software in the software platform, and is used for voice input matching and selection of corresponding local fault operation scenarios in the typical fault and scheduled inspection project library, simulation parts library, simulation tool library, parts recognition prompt entry library and fault handling process prompt entry library in the software platform.

[0009] Furthermore, the simulation parts library dynamically calls out corresponding parts according to the practical training tasks and realizes the insertion of part models, and there are no less than 20 types of parts. The simulation tool library dynamically calls out corresponding tools according to the practical training tasks, and realizes the prototype display of tools in the scene, the action interaction between operation models, and there are no less than 10 types of tools. The part recognition prompt entry library interactively displays the corresponding device names and function prompt entries based on the wireless transceiver software and the voice input and analysis software. The fault handling process prompt entry library calls out corresponding prompt entries based on the selected typical faults and scheduled inspection events, and guides and helps customers complete virtual operations. The fault handling process prompt entry library is only used for simulation training.

[0010] Furthermore, the training record and evaluation system and the virtual three-dimensional VR simulation and voice guidance system are started synchronously to record all operation data in the virtual three-dimensional VR simulation and voice guidance system in real time and generate a training report.

[0011] Furthermore, the operation objects of the virtual three-dimensional VR simulation and voice guidance system are photovoltaic power station components.
