摘要
为研究高速磁浮列车测速定位问题,从系统工程角度阐述测速定位问题的技术本质是车地时空关系的表达,功能目标是实现车地时空信息的实时获取与交互,重点在于信息层面而不是单纯的测速定位技术研究应用或系统构建。分析归纳了在技术选用和系统设计时需充分考虑的时空一致性、时空约束性和时空敏感性特征以及五方面具体特点;汇总了高速磁浮列车测速定位技术研究进展,包括感应环线技术、齿槽检测技术、车载多普勒雷达技术、脉宽编码检测技术、射频应答器技术、卫星导航技术以及光纤测量技术,并分别从原理、优缺点、适用性、应用情况等方面进行分析。鉴于目前的研究绝大多数集中于技术层面,从工程化角度出发展望了测速定位技术和系统的发展,认为雷达技术、通感一体化技术、基于惯导的组合测速定位技术以及摄像测量技术值得关注,以工程化为目标的系统研究、设计和优化还需深入进行,需要跟随技术发展对多种技术组合进行持续研究和试验,并应构建测速定位技术的指标体系和评价方法。针对目前的系统架构下不能充分支持时空信息共享的问题,给出了一种总线架构参考。
This paper summarizes the problems of speed measurement and positioning of high-speed maglev train.From the perspective of system engineering,this paper expounds that the technical essence of speed measurement and positioning is the expression of space-time relationship between train and ground,its functional objective is to realize the real-time acquisition and interaction of space-time information between train and ground,the emphasis is on the information level rather than the simple research and application of speed measurement and positioning technology or system construction.This paper analyzes and summarizes the characteristics of space-time consistency,space-time constraint and space-time sensitivity that should be fully considered in the technical selection and system design,as well as five specific characteristics.This paper summarizes the research progress of speed measurement and positioning technology of high-speed maglev train,including induction-loop technology,detection technology based on the long stator slot structure,vehicle Doppler radar technology,RFID technology,GNSS technology and optical fiber measurement technology,and analyzes the principle,advantages and disadvantages,applicability and application.In the consideration of most of the current research focuses on the technical level,this paper looks forward to the technical and system development of speed measurement and positioning from the perspective of engineering,it is believed that radar technology,integrated sensing and communication technology,integrated speed measurement and positioning technology based on INS,and videometrics technology deserve attention,and believed that the research,design and optimization aiming at engineering need to be further developed,and the continuous research and test of various technology combinations are required with the development of the technology,and the technical index system and evaluation method of speed measurement and positioning technology are needed to established.Aiming at the problem that the current system architecture cannot fully support space-time information sharing,a bus architecture is given as a reference.
