摘要
以移动信号通信理论为基础,构建了一种基于分布式VR技术的城市轨道交通控制模型。分布式VR系统构成具体包括了交互层、应用层、数据库层、状态管理器层、和通信层,中心服务器通过无线网络与各控制对象建立联系。分布式VR系统通过平移、缩放、和旋转等同步操作,在后台实时仿真出列车的运行状态,并对每辆列车的当前位置、当前速度、前后车距等信息进行判读、调整、和集中控制;为了保持车地之间的通信畅通,均衡调整每条通信信道的数据负载情况,降低车地之间的通信延迟。仿真结果显示,分布式VR系统的反应速度快、能耗低、通信能力较强,在保证对城市轨道交通实施精准控制的同时,也能够有效调整通信负载。
Based on the theory of mobile signal communication,an urban rail transit control model based on distributed VR technology is constructed.The distributed VR system specifically includes interaction layer,application layer,database layer,state manager layer and communication layer.The central server establishes contact with each control object through wireless network.The distributed VR system simulates the train operation in real time in the background through synchronous operations such as translation,zoom and rotation,and interprets,adjusts and controls the current position,cunent speed and front and rear distance of each train;In order to maintain smooth communication between vehicles and ground,the load of each channel is balanced and adjusted to reduce the communication delay between vehicles and ground.The simulation results show that the distributed VR system has faster response speed,lower energy consumption and strong communication ability.It can not only ensure the accurate control of rail transit,but also reduce the overall operation cost.
