Description

Technical Field

[0001] The present invention relates to the field of disassembly animation production, and particularly relates to a method for producing a disassembly animation of a multi-task scenario of virtual trackside signal equipment. Background Art

[0002] Trackside signal equipment is an important signal safety equipment for rail transit, mainly including: switch machines, signal lamps, axle counters, balises and other equipment. Among them, the main uses of each equipment are as follows: (1) Switch machine: used to convert the position of the turnout, achieve locking, prevent the turnout from being converted by external force, and correctly reflect the actual position of the turnout. When the turnout is squeezed or in the "four-open" (both side-point rails are not closely attached) position due to reasons, an alarm and indication are given in a timely manner. (2) Signal lamp: used to complete the interlocking task and ensure the safety of the route on the railway line. (3) Axle counter: used to calculate the number of axles of the vehicle entering and leaving the section, and analyze and calculate whether the section is occupied by a vehicle. (4) Balise: transmits data to the station signal equipment to achieve mutual communication between the ground and the line.

[0003] Due to the characteristics of trackside signal equipment such as strict safety requirements, long service life, complex working principles of electrical and mechanical components, large number of trackside signal equipment, high working frequency and professional technical barriers, it is difficult for training personnel to master the operation process of trackside signal equipment, with slow progress and poor experience. Therefore, there is an urgent need for a new technical method to improve the proficiency of training operations.

[0004] Virtual reality technology is an important direction of simulation technology. It uses a computer to simulate and generate a virtual world in a three-dimensional space, providing users with visual and other sensory simulations, making them have a feeling of being on the scene and experience, and can observe things in the three-dimensional space in a timely and unrestricted manner. Unity3D is a professional game engine developed by Unity Technologies. Its powerful physics engine and particle system can well simulate and control scenes in the real world, making it not only limited to the game development field, but also having good application value in the fields of industrial design, system simulation and architectural visualization. Among them, the Animator animation component has powerful functions and can use externally imported animations and self-made model animations. The main steps include: opening the Animation window, selecting the object to make the animation, creating a new animation Clip, editing, previewing and modifying the animation.

[0005] Trackside signal equipment, as an important signal safety equipment, plays an important role on the line. Therefore, it is necessary to increase on-site maintenance requirements and professional knowledge. However, there are some problems in the training of multi-task scenarios of trackside signal equipment:

[0006] (1) Trackside signal equipment is mainly installed on the line for operation and does not have the conditions for on-site viewing by non-professionals.

[0007] (2) There are many types of trackside signal equipment. Due to the existence of multiple equipment types, installing these devices may involve different technologies and procedures, so complex situations may be encountered in the project. This includes ensuring the correct installation of the devices, coordinating with other systems, and meeting relevant requirements. Once these devices are installed, their requirements in terms of operation and use may be very high. This includes maintaining, monitoring, upgrading, and ensuring the normal operation of the devices to ensure safety and efficiency.

[0008] (3) The internal mechanical structure of trackside signal equipment is complex. This type of equipment is used in different working scenarios and may need to cope with different operation requirements, environmental conditions, or operating modes. Due to changes in the working scenario or wear of the equipment, it may be necessary to regularly or temporarily replace the internal parts of the equipment to ensure its normal operation.

[0009] (4) The materials of trackside signal equipment are mainly two-dimensional plane drawings, which usually contain a large amount of text descriptions. Compared with graphics or charts, they are less intuitive and it is difficult to visually understand the structure and spatial layout of the equipment. This may lead to certain limitations in the understanding and interpretation of the equipment because it is difficult to provide a specific impression of the three-dimensional sense and actual appearance of the equipment in this way.

[0010] (5) The current training method mainly relies on oral teaching and empirical feelings to complete, and lacks professionalism and integrity. Summary of the Invention
