基于系统动力学特性的虚拟舱室灭火交互模型

虚拟火灾与灭火行为的对抗关系模型是损害控制指挥模拟训练环境计算机模拟过程的基础性工作之一。基于作战仿真的方法,将势的概念引入损害与损管措施的对抗交互之中,二者之间的对抗可以理解为势的变化。针对对抗过程的参数选取以及量化问题,给出了损害势与损管措施势的量化方法和计算过程,建立了二者动力学关系模型,结合典型状态下火灾与灭火措施的对抗关系,给出了交互模型的解析形式,通过人员实际损害管制训练的结果统计,确定了模型参数,并对模型的适用性进行了验证。仿真结果与实验数据比较,该模型可用于模拟舱室内虚拟火灾的灭火过程。

An Interactive Virtual Compartment Fire Extinguishing Model Based on System Dynamic Characteristic

The virtual fire extinguishing model is one of the basic computer simulating processes related to the disaster control commanding simulation training environment. Based on operational command simulation method, the conception of the potential is introduced into the interactive relationship between the disaster and disaster control measures. The nteractive confrontation between the disaster and the control measures can be seened as the potential interactions. For the parameter selection and quantization, the disaster potential and disaster control measures potential are given, and the quantizing potential scale and the calculating process are proposed. A dynamic relationship model is established. Combined with the classic fire extinguishing states, an analytical form model for confrontation relationship is proposed. According to the statistics of training results of the actual disaster control crew, the model parameters are determined. The simulation result is compared with the experiment data. The result shows that the model can be used to simulate the fire extinguishing process of virtual compartment.
