The present application belongs to the technical field of personnel evacuation data processing, and in particular, relates to a method, device, computer-readable storage medium and terminal device for predicting personnel evacuation time. The method includes: acquiring scene data of a target evacuation scene; using a preset evacuation time prediction model to process the scene data of the target evacuation scene to obtain the personnel evacuation time under the target evacuation scene; wherein, the The evacuation time prediction model is a neural network model obtained by training a preset evacuation data set. The evacuation data set includes evacuation samples corresponding to various preset designated evacuation scenarios, and each evacuation sample includes a designated evacuation scenario. scene data and the corresponding evacuation time. Through the present application, an accurate mapping relationship between scene data and personnel evacuation time is established in the model, which greatly reduces the amount of calculation and shortens the calculation time while maintaining high accuracy.
Description
technical field [0001] The present application belongs to the technical field of personnel evacuation data processing, and in particular, relates to a method, device, computer-readable storage medium and terminal device for predicting personnel evacuation time. Background technique [0002] Personnel evacuation in emergency situations is an important branch of safety science, which has been extensively studied by scholars at home and abroad for many years. In the event of an emergency such as a fire, the evacuation time is an important indicator for evaluating the evacuation capability of the space environment. Accurate and rapid estimation of evacuation time is very important for improving the safety level of buildings, designing reasonable evacuation strategies, and reducing human disasters. [0003] At this stage, the calculation methods of evacuation time mainly include empirical formula method and personnel evacuation simulation calculation method. The empirical formu...
