摘要
探讨了列车运行记录系统的硬件结构以及记录系统与列车主监控系统之间的数据通信方式,并对随车检测单元与数据记录单元之间的通信接口、大容量数据存储器的扩展以及数据存储器的掉电保护电路做了较详细的阐述,系统采用性能优越的 RUPI-44系列通信控制单片机8344,实现车载微机系统之间的高速可靠的数据通信.
In this paper,hardware architecture and communication pattern be- tween the main monitor and its recording system are discussed.Communication interface between the on-board detecting unit and the data recording unit, expansion of the capacious data storage and the powerdown safeguard circuit of the data storage are also discussed in datail.To realize high speed,reliable data communication among the units of the system,the superior 8344 communication microcontroller of the RUPI-44 series is used.
