Problems solved by technology

However, there is still a lack of effective methods at home and abroad on how to construct the emergency evacuation process of miners in underground emergencies
There is no relevant patent application in this aspect, and some published papers mostly focus on the geometric modeling of virtual mines

Embodiment Construction

[0027] A non-limiting embodiment is given below in conjunction with the accompanying drawings to further illustrate the present invention.

[0028] The first is the system simulation framework. The simulation framework is composed of five parts: geometric scene simulation engine, crowd simulation engine, event recorder, scene database, and human-computer interaction interface. All parts coordinate with each other to complete the work of the entire simulation system. Some specific implementation functions are as follows:

[0029] The geometric scene simulation engine part mainly generates 3D image scenes, such as the entire underground environment, obstacles, exits, exit signs, etc., and then realizes scene rendering and dynamic simulation with characters through simulation software. Our 3D modeling of objects in the scene is realized through Multigen Creator, and the simulation software uses VegaPrime.

[0030] In the simulation framework, the scene database includes a geomet...

Abstract

The invention provides an underground emergency evacuation virtual crowd simulation method based on multiple intelligent agents. A virtual mine emergency evacuation crowd simulation frame is built by using the underground emergency evacuation virtual crowd simulation method based on the multiple intelligent agents. The virtual mine emergency evacuation crowd simulation frame is mainly composed of five portions of a crowd simulation engine, a geometric scene simulation engine, a scene database, an event recorder and a human-computer interaction interface. In consideration of different understandings on mine knowledge and different behavior decisions of miners playing different roles when mine disasters occur, a multiple intelligent agent miner crowd emergency evacuation module and a crowd emergency evacuation algorithm for the different roles of the miners such as job foremen, expert miners, common miners and rescuers are built by using the underground emergency evacuation virtual crowd simulation method based on the multiple intelligent agents according to a role theory. The underground emergency evacuation virtual crowd simulation method based on the multiple intelligent agents can simulate true situations of a mine well, has good universality and verisimilitude, and can provide effective technical support for underground security accident analysis and prevention, mine safety training and rescue exercises.

Description

technical field [0001] The invention relates to the fields of virtual reality, artificial intelligence, coal mine safety and the like, in particular to an emergency evacuation simulation method for underground virtual crowds based on multi-agents. Background technique [0002] The coal mining industry is an important basic industry that promotes my country's economic development. It is directly related to the country's economic lifeline and is the basic guarantee for economic development. At the same time, the coal industry is a high-risk industry. According to incomplete statistics, 60% of the annual industrial casualties The above is from the coal mining industry. A large number of accidents show that if the crowd can be effectively evacuated when a mining accident occurs, the number of victims will be significantly controlled. [0003] However, due to the characteristics of suddenness, uncertainty, emergence, and catastrophe in the occurrence of mine disasters, as well as...
