真空管道高速飞行列车车地无线通信技术

摘要
近几年,随着信息技术发展越来越迅速及其应用领域的不断扩张,交通技术的新变革也正渐渐冲破桎梏.真空管道高速飞行列车是一种新型轨道交通技术,可实现磁悬浮列车在接近真空的低压管道中高速运行.由于轮轨摩擦和空气阻力可忽略不计,因此高速飞行列车理论速度可达4 000 km/h.本文基于最新的宽带无线通信理论与技术,针对真空管道高速飞行列车无线宽带接入应用场景,尝试思考一套有效解决超高速移动无线宽带接入的理论与增强技术体系.初步在真空管无线接入、新型漏泄波近场耦合等方面形成系统的解决方案,为真空管道高速飞行列车的宽带接入提供理论与技术支撑.
With the gradual maturity and in-depth applications popularization of information technology,a new transportation technology revolution is brewing. The high-speed vacuum tube flying train is a novel rail technology. The maglev train can run at ultra-high-speed in the low-pressure tube close to the vacuum. Because the wheel-rail friction and air resistance can be neglected,the theoretical speed of highspeed flying train can reach 4 000 km/h. Aiming at the application scenarios of wireless broadband access for high-speed flight trains in vacuum tubes,this paper attempts to consider a theoretical and enhanced technology system based on the latest broadband wireless communication theory and technology to effectively solve the problem of ultra-high-speed mobile wireless access. The preliminary systematic solutions in the aspects of vacuum tube wireless access and new leakage near-field coupling are initially formed,providing theoretical and technical support for broadband access of vacuum tube high-speed flight trains.
