Embodiment 1

[0059] like figure 1 As shown, the embodiment provides a practical application system consisting of a three-dimensional model subsystem, a process model subsystem and a virtual reality subsystem on three computers. Among them, the process model subsystem is formed by coupling the simulation control system and the dynamic mechanism model to provide reliable dynamic data for the virtual reality subsystem. The dynamic mechanism model comes from the process simulation subsystem, and the simulation control system comes from the process control subsystem.

[0060] A three-dimensional model subsystem is established on the computer 1 . The 3D model subsystem uses the 3D drawing software 3DMax to add basic geometric elements, including lines, circles, and rectangles, according to the engineering drawings, and builds equipment models through translation, rotation, stretching, splicing, subtraction, and Boolean operations. After the model is built, the layout is optimized, and informat...

Embodiment 2

[0072] like figure 2 As shown, the practical application system provided by the embodiment is composed of a three-dimensional model subsystem, a process simulation subsystem, a process control subsystem and a virtual reality subsystem. Among them, the three-dimensional model subsystem and the virtual reality subsystem are in figure 2 done on computer 3. At the same time, the simulation control system and the dynamic mechanism model in the process model subsystem are decoupled to obtain the process simulation subsystem and the process control subsystem, which makes the production management and control more flexible.

[0073] The three-dimensional model subsystem on the computer 3 is different from the engineering drawing modeling method in Embodiment 1, and a three-dimensional model of the field factory area is established by a combination of oblique photography technology and laser scanning technology. By carrying multiple sensors on the same flight platform, field images...

Abstract

The invention discloses a three-dimensional immersive chemical virtual simulation system. The system comprises a three-dimensional model subsystem, a process simulation subsystem, a process control subsystem and a virtual reality subsystem which are mutually independent. The mutually independent subsystems can be established on the same computer / server, and can also be established on a plurality of computers / servers. According to the requirements of the simulation system for the functions of the subsystems, software or hardware conforming to specific communication procedures is adopted to establish the subsystems, and hardware replacement and software updating are carried out when necessary. A user can adopt a system developed from a non-single source according to requirements, free combination of subsystems is carried out to meet diversified requirements, and openness, flexibility and expansibility of the simulation system are improved.

Description

technical field [0001] The invention belongs to the field of virtual reality and digital factory systems, and in particular relates to a three-dimensional immersive chemical virtual simulation system. Background technique [0002] The chemical production process is complex, with many equipment, machines, and pipelines. The materials to be processed are often dangerous substances, and the unit operating conditions are harsh. There are many potential risk factors in production, and the possibility and consequences of accidents are more than other industries. for serious. [0003] The occurrence rate of safety accidents in the chemical industry and the severity of the consequences of the accident remain high in various industries. The main reasons for this phenomenon are the lack of safety awareness or improper operation of production personnel. Safety training for chemical safety production often lacks immersion and interactive functions close to reality. It is difficult for ...
