Problems solved by technology

In the traditional theoretical learning link, the knowledge content is comprehensive and the theory is strong, but it is not vivid enough, the interaction is not enough, and the effect of combining with the actual production is not good; in the practical training link, the students can see the actual operation object, but Practical training is easily restricted by factors such as the differences in work sites, operating devices, and weather. The opportunities for practical operations and work items are limited. Relying on traditional methods to carry out staff professional skills training is no longer suitable for the needs of the rapid development of the current power grid

Embodiment 1

[0037] see figure 1 , to study the cable joint making module based on VR technology. see figure 2 Based on VR technology, there are two modes in this project for the production of cable joints: virtual observation and simulation operation. In the present invention, a virtual environment system including 3D animation, sound and vibration is established based on VR technology, which can be fed back to operators through visual, auditory, tactile and other forms. It supports operators to conduct virtual observation and interactive simulation operation training, and visualizes the operation process and results in the form of simulation animation, which effectively improves the theoretical knowledge level and practical operation experience of trainees.

Embodiment 2

[0039] see image 3 , developed a real-scene building module for cable joints based on AR technology. The real scenes of cable joints in cable trenches at different voltage levels based on augmented reality technology provide strong support for power workers to carry out tests, inspections, inspections, maintenance, etc. Augmented reality has three important features and is also its three key technologies Where: ①Three-dimensional registration technology, that is, using automatic tracking technology to accurately align the virtual model with the real object; ②Virtual-real fusion display technology, so that the virtual model and real-world objects coexist in the user's field of vision; ③Human-computer real-time interaction With technology, users can interact with real and virtual objects in the field of view in real time.

Embodiment 3

[0041] Developed a cable joint fault repair module based on VR+AR technology, including three fault scenario simulations. The main scientific problems of virtual reality include three categories: modeling method, performance technology, human-computer interaction and equipment. However, there are a series of problems at present. The main problems include heavy modeling workload, high simulation cost, and matching with the real world. Insufficient level and credibility, etc., by combining AR technology with VR technology, a new visualization environment can be created by merging the real world and the virtual world. In the new visualization environment, physical and digital objects coexist and interact in real time. It is the staged ultimate form of AR and VR technology. By introducing real scene information in the virtual environment, this technology sets up an interactive feedback information loop between the virtual world, the real world and users, and realizes common faults ...

Abstract

The invention discloses a cable joint manufacturing and operation and maintenance skill training device and a cable joint manufacturing and operation and maintenance skill training method based on VRand AR technologies. The technical scheme is composed of four parts including theoretical learning, cable joint manufacturing simulation, fault overhaul, and examination and evaluation. A simulation environment created by adopting the VR and AR technologies highly restores a power operation site, and then workers can complete simulation operation training of different businesses under the state without any danger. With the technical scheme, the defects of the traditional cable joint analogue simulation can be effectively overcome, by establishing a technical knowledge visual interface and theoperation skill teaching simulation environment, trainees can be quickly familiar with the scene and skillfully perform various operations, and meanwhile, an ST-GCN algorithm is utilized to perform personnel action behavior recognition analysis and normalize standardized personnel operation, so that the professional skill of front-line workers is effectively improved.

Description

technical field [0001] The invention relates to the technical field of AR / VR and deep learning, in particular to a device and method for training cable joint production and operation and maintenance skills based on VR+AR technology. Background technique [0002] In recent years, power cables have been widely used, mainly because of their low cost and some of their own excellent features, but at the same time, power cables have also exposed some problems, the most notable of which is the difficulty of later maintenance. The power system is inseparable from our life, and the cable joint is an important part of it. The production process of cable joints is complex, difficult and difficult to master, and cable joint failures account for more than 80% of cable failures and hidden dangers. Once a failure occurs, it will directly affect the safe operation of the entire power system. At present, the commonly used cable joint production and maintenance enablement is mainly to implem...
