Abstract: In order to fill the request of the pumper training in airfield and improve the effect of training, this paper designs and achieves the system of fire control in airfield. The system contains visual simulation, joy stick data-getting part and communications. Three collision detection vectors in visual simulation can keep the position and attitude of the pumper. The joy stick data-getting part and communications transmit the data to visual simulation by the technology of DirectInput and UDP. That ensures the reality and real time. The result shows that the system can reach the training request.

Key words: simulator, collision detection vector, joy stick, User Datagram Protocol（UDP）, view simulation

摘要： 为了满足机场消防车训练的要求，提高训练效果，设计并实现了机场消防车训练视景系统。该系统由视景仿真模块、操纵杆数据提取模块和通信模块组成。视景仿真模块采用三个碰撞检测向量确保了消防车运动中准确的位姿；而操纵杆数据提取模块和通信模块分别采用DirectInput技术和UDP通信技术，为视景仿真提供实时数据，确保视景演示的实时性与真实性。实验结果表明，该系统完全满足机场消防训练的要求。
