城市轨道交通工程装备限速保护系统研究

Research on Speed Limit Protection System of Urban Rail Transit Engineering Equipment

以地铁网轨检测车项目为例,研究地铁限速保护模式,阐述了在原网轨检测车基础上加装限速保护系统的原理、功能、硬件组成与系统保护措施层级,使得网轨检测车作业时尽可能模拟旅客列车运行工况,提高了网轨检测车的安全运行指数。

Taking the project of metro network rail detection vehicle as an example, the speed limit protection mode of metro was studied. The principle, function, hardware composition and system protection level of adding speed limit protection system on the basis of the original network rail detection vehicle were described. The network rail detection vehicle simulated the passenger train operation condition as much as possible, the safety factor of the network rail detection vehicle was improved.
