摘　　要：列车定位技术是实现列车运行控制的关键技术之一。由于连续式列车定位随着列车运行时间的增加会产生一定的累积定位误差,为消除这种累积误差,通常还需采用辅助定位技术对列车位置进行校正。本文提出了一种基于电磁感应的磁浮列车绝对定位系统,可作为列车定位的辅助校正系统;并结合磁浮列车的功能需求和运行工况,对该绝对定位系统进行特殊结构设计,使其具有方向识别、抗振等能力。该系统作为一种新型磁浮列车绝对定位系统,可为后续磁浮列车定位系统设计提供理论支撑。Train positioning technology is one of the key technologies to realize train operation control.For continuous train positioning technology,a certain cumulative positioning error will be generated with the increase of train running time.To eliminate this cumulative error,some auxiliary positioning technologies should be used for train positioning correction.So,the absolute positioning system for maglev train based on electromagnetic induction is proposed as an auxiliary correction system for train positioning.Combined with the functional requirements and operating conditions of maglev trains,the system is designed with special structures to enable the system direction recognition,anti-vibration and other capabilities.As a new type of absolute positioning system for maglev trains,this system can provide theoretical support for the design of subsequent maglev train positioning systems.
