What does virtual simulation mean?

To put it simply, virtual simulation is to generate a three-dimensional dynamic real scene by computer, and to dynamically and realistically imitate the structure, function and behavior of the system and the thinking process and behavior of people participating in the system control.

At present, all walks of life have begun to apply virtual simulation technology to save costs, improve efficiency and promote innovation and development. At present, the common application fields are education and training in universities and vocational schools; Working in high-risk industries such as chemical industry, mining and dangerous chemicals; Construction engineering and design industry; Medical industry; Automobile and aviation industry; Urban planning and transportation; Agriculture, forestry, animal husbandry and so on.

The application of 1.Obel virtual simulation in the field of higher education;

1, technical architecture of physical virtual simulation platform

Beijing Obel physical virtual simulation teaching platform adopts B/S structure design, which makes the system meet the business needs and future development needs. It is mainly divided into three parts: simulation learning module, experimental teaching module and simulation algorithm engine module;

The system adopts the structure of combining CS and BS. Through the BS architecture, users can access the management platform, view the software list, course list and other functions, make statistics on learning records, test scores and other information, and start the 3D simulation project. Three-dimensional simulation realizes data synchronization, human-computer interaction interface operation, intelligent scoring and teacher station management by accessing the database, in which the data of the database comes from the calculation of the mechanism model.

2.Ober "Hyperuniverse" campus construction scheme.

Hyperuniverse+teaching can greatly improve the efficiency, go beyond the limitation of not being able to communicate face to face at present, and let everyone better interact with others or online in a higher dimension. Bring a richer and more immersive interactive experience.

1, friend+civilization system three-dimensional interaction: support users to greet opposite characters in 3D scenes and synchronize actions.

2. Digital person teaching: information is recorded as digital person endorsement voice explanation or played with the classroom.

3. Open software creation: teachers' software production ability and material database based on 0.

4. Higher-dimensional online teaching materials and courses: PPT screen+audio+video +3D trajectory screen+simulated operation data+interactive information of stereoscopic teaching.

3. Digital Twin Virtual Simulation Software

In the virtual simulation part of Aubel soft digital twin Substation, by collecting and summarizing the power grid data, a digital twin which is the same as the real power grid is constructed in the virtual world, and the real-time monitoring of the physical operation state can be realized. In addition, the analysis and simulation of data can also find potential faults in time, so as to repair them in time and nip in the bud. Beijing aubert Software Technology Development Co., Ltd. takes the substation in the power system as the object, and combines BIM technology with real-time data of equipment to build a digital duplex substation which is completely consistent with the real scene.

Second, the application example of Obel virtual simulation in high-risk operation field:

1, chemical virtual simulation software

The virtual simulation software of Beijing Aobo Chemical Industry uses virtual reality technology to simulate the factory environment and operation process, and finally constructs the mode of "3D virtual field station+central control room". Typical chemical engineering units are extracted by simulation technology, so that students can realize the mode of combining theory with practice without leaving school. The software integrates a wealth of knowledge points, which can consolidate and enrich students' theoretical knowledge.

2, coal mine safety virtual simulation education and training system

Under the background of adhering to the national policy standards and meeting the needs of enterprises, Ober investigated the needs of a large number of users for enterprises and training bases, and combined them with the mine safety production plan of the emergency management department. On this basis, an integrated construction scheme can be provided to meet the training of mine intelligent personnel and the quality improvement project of mine-related employees. Give full play to the advantages of virtual simulation and process modeling technology, construct three-dimensional scenes such as buildings and mechanical equipment on the well and underground scenes such as shafts, tunnels, water pipes and harvesters, and carry out interactive, distributed and immersive design according to the training needs of employees or students, which breaks through the limitations of traditional training forms and creates a visual, integrated and standardized virtual simulation education and training system for coal mine safety.
