港口机械远程虚拟监控系统研究

结合虚拟现实技术实现基于传感器数据驱动的港口机械群远程监控。采用3DMax和Pro/Engineer等工具建立完整的港口场景和港口机械模型库，利用DirectX开发虚拟场景渲染引擎，通过现场总线和无线传感器网络采集港口机械的位置、姿态和运行状况信息，并据此在渲染引擎中实时驱动虚拟模型。实现一个具有高度沉浸感和交互性的三维港口机械群实时监控环境，并利用中心数据库的专家诊断系统和Web Service技术实现故障预警和故障诊断。

Research on Remote Virtual Monitoring System of Port Machinery

The remote monitoring for port machinery based on sensor data driven is implemented combined with virtual reality technology. The total scene and the port-machinery model library are established by such tools as 3DMax and Pro/Engineer. DirectX is adopted to develop the rendering engine of virtual scene. Field bus and wireless net of sensors are used to collect information of port machinery, including location, orientation and working state information, according to which the virtual model is driven in this rendering engine. A real-time monitoring environment is implemented, which is 3-dimensional, highly vivid and interactive. On this basis, expert diagnosis system of the central database and Web Service technology are used to implement predicted alarm and diagnosis of malfunctions.
