Embodiment Construction

[0036] Such as figure 1 The shown VR-based tunnel evacuation escape test method includes steps:

[0037] S1: Build a test tunnel model, and simulate the virtual scene of accident conditions in the tunnel in the test tunnel model; the virtual scene of accident conditions simulated in this application mainly includes extreme scenes such as tunnel fire, tunnel explosion, and malicious vehicle collision ;

[0038] S2: Collect the escape time information, real-time position coordinate information and escape speed information of the test personnel participating in the escape test when they escape in the virtual scene of the accident condition;

[0039] S3: Combining with the virtual scene of accident conditions, according to the escape information of the test personnel collected in step S2, reconstruct the evacuation trajectory of each individual participating in the escape test; the escape trajectory mainly includes the obstacle avoidance selection during the escape process and th...

Abstract

The invention discloses a VR-based tunnel evacuation and escape test method and system. The method comprises the steps: building a test tunnel model, selecting an accident condition scene, superposingthe accident condition scene to a virtual environment to complete the test setting, giving test participants the feeling of being located in an extreme scene, and improving the authenticity of test data; escape time information, real-time position coordinate information and escape speed information of testers of different escape tests during escape in an accident condition virtual scene are collected; acquiring an evacuation escape track of an escape tester; by analyzing escape response time, escape speed, escape path selection and evacuation and escape effectiveness among different testers and analyzing test results of different scenes. The completeness of influence factors in the test process can be verified. The data support is provided for perfection of the test scenes, and the data support is provided for formulation of evacuation and escape strategies.

Description

technical field [0001] The invention relates to a VR-based tunnel evacuation escape test method and system. Background technique [0002] At present, some experimental studies have been carried out in China on the evacuation and escape of personnel in tunnels under fire conditions. However, most of the experiments have not been carried out in real fire scenarios, and only simulated fire scenarios through extremely small-scale fire plates and smoke generators. Its fire is less realistic, it is difficult to create real fire conditions, and the collected evacuation data is not close to reality; in addition, there is no reasonable evacuation test at home and abroad for explosions, malicious collisions and other extreme conditions other than fire. Methods. Contents of the invention [0003] The purpose of the present invention is to provide a VR-based tunnel evacuation escape test method and system to solve the existing problems. [0004] In order to solve the above-mentioned...
