摘　　要：提出了一种适用于长距离轨道车辆的新型定位测速系统,可实现对长距离轨道上多辆车的相对和绝对定位测速,且其模块化设计便于工程化的生产和应用。重点介绍了系统的结构及分区处理器、中间处理器和上位处理器的工作原理,并详细讲解了有效子块的多级选择、绝对位置标定、故障识别及冗余设计等关键技术,给出了系统的软件设计。所述系统在某1500 m轨道车辆的定位测速上得到成功应用。A set of location and speed detection system applying to long-distance track vehicles was presented. It can realize absolute and relative detection of location and speed, and its modularization design is convenient for producing and applying in projection. The structure of the system and the working principle of the distributed processors, the middle processors and the central processors were emphasized. The key technologies were explained particularly, such as multi-class＇ choices for effectual modules, absolute position marking, fault -identify, redundancy design and so on. Furthermore the software design for the system was introduced. The system designed as above was applied successfully to a running control system for a 1 500 m long rail vehicle.
