基于Quest3D的采煤机虚拟培训系统设计

Design of virtual training system for shearer operation based on Quest3D

针对目前采煤机培训方式不能立体化多角度地展示采煤机操作过程的问题,设计了基于Quest3D的采煤机虚拟培训系统。该系统由下位机和上位机组成,二者通过RS232协议通信。下位机用来模拟采煤机的控制平台,以STC89C52单片机为核心的控制电路实现对外部操作信号的接收、处理和传输。上位机使用3DMax建模软件创建虚拟场景所需的模型,通过Quest3D三维引擎开发平台完成虚拟场景搭建,并依据下位机的命令对模型进行控制。该系统实现了采煤机虚拟培训功能,缩短了培训周期,降低了培训成本。

In view of problem that current training methods for shearer operation can not show three- dimensional operation process of shearer from multi-angle, virtual training system based on Quest3D was designed. The system consists of lower machine and host machine, and they communicate via RS232 protocol. Lower machine is used to simulate control platform of shearer, and the control circuit taking STC89C52 microcontroller as the core realizes receiving, processing and transmission of external operation signal. Host machine uses 3DMax modeling software to create required model of virtual scene, builds virtual scene by Quest3D three engine development platform, and controls the model according to order of the lower machine. The system implements virtual training function of shearer, shortens training cycle, and reduces training cost.
