“导航原理与系统”虚拟仿真实验教学体系构建

Construction of Virtual Simulation Experiment Teaching System of the Course in“Navigation Principle and System”

“导航原理与系统”是民航类高等院校的一门专业必修课,但由于DME、VOR和ILS等陆基导航设备占地面积大、造价昂贵,实际运行需要有许可和诸多配套设施支持,学生难以接触到实际设备来提高工程实践能力。根据工程教育认证理念及其毕业要求,构建适用于“导航原理与系统”课程的虚拟仿真实验教学体系,结合SELEX公司的典型设备(1150 DVOR、1119A DME)和NORMARC公司的NM7000仪表着陆系统,分别设计了DVOR/DME地面信标天线安装与板件互联虚拟仿真实验系统和ILS航向信标信号测试与排故虚拟仿真实验系统。该实验灵活高效、易实施、投入小,有助于学生深刻掌握DME、VOR和ILS等陆基导航设备的工作原理、信号辐射场特征和实际维护的典型操作,对民航高等院校实施工程教育及陆基导航实验室建设具有重要的参考价值。

The course in“Navigation Principle and System”is a professional compulsory course closely combined with the industry in civil aviation colleges.However,due to the large area,high cost of land-based navigation equipment such as DME,VOR and ILS,the actual operation requires permission and supporting facilities,and it is difficult for students to have access to actual equipment to improve their engineering practice ability.According to the engineering education certification concept and graduation requirements,this paper constructs a virtual simulation experiment teaching system of the course in“Navigation Principle and System”.Combined with SELEX’s typical equipment(1150 DVOR and 1119A DME)and NORMARC’s NM7000 instrument landing system,the virtual simulation experiment system of DVOR/DME ground beacon antenna installation and board interconnection and ILS course beacon signal test and troubleshooting virtual simulation experiment system are designed.The experiment is flexible,efficient,cheap and easy to implement,and it can help students master the working principle,signal radiation field characteristics and typical operation in practical maintenance of DME,VOR,ILS and other land-based navigation equipment,which is of great reference value for civil aviation colleges to implement engineering education and construct land-based navigation laboratory.
