列车速度防护装置中记录单元的设计与实现

Design and Implementation of Data Logging Unit in Train Speed Protection Device

为了保障地铁列车的安全运行和车辆维护的需要,开发设计了一种基于串行Flash存储器的数据记录单元,可以自行采集地铁列车速度防护装置的运行数据并自动分析、记录,另外还提供对外通信接口,可用于上位机对整个防护装置的实时监控及故障数据转储。该系统通过了运行试验和现场鉴定,可以满足在恶劣环境下对列车速度防护装置设备进行实时可靠的数据记录和状态监控的需求。

In order to ensure the safety of train running and meet the demand of train maintenance,a serial-flash-memory based data logging unit was designed.This system could not only gather,analyze and record running data of train speed protection device automatically,but also provide external communication interface for host computer real-time monitoring and data dump.With operation test and field identification,the design was proved satisfying real-time and reliable data recording and status monitoring of speed protection device in harsh environments.
