铁路大型电子DCS通信系统的优化设计与实现

Optimization design and implementation of large electronic DCS communication system for railway

由于铁路运输中存在较多的影响因素,传统铁路大型电子通信系统无法有效保障铁路运输安全。因此,构建能够有效提升铁路运输安全性能的铁路大型电子DCS通信系统。该系统由通信主站模块、通信从站模块和信号采集模块组成。通信主站模块利用TMS570LS技术获取对铁路车站联锁的管理命令,并将其传输到通信从站模块。通信从站模块根据管理命令管理铁路车站联锁,并进行信号采集模块的驱动工作。信号采集模块被驱动后,开始采集铁路车站联锁信号。通信从站模块和信号采集模块中的信号均传输到通信主站模块进行统一的分析、优化和预警。系统软件部分设计了信号传输损耗函数以及系统存储器优化语言。实验结果表明,所设计的系统能够有效提升铁路运输安全性能,增加铁路车站通车量。

Since the traditional large electronic communication system for railway can＇t effectively guarantee the transporta- tion safety of the railway due to the multiple influence factors existing in the railway transportation, a large electronic DCS sys- tem of the railway was constructed, which can improve the railway transportation safety effectively. The system is composed of the communication master station module, communication slave station module and signal acquisition module. The TMS570LS technology is used in the communication master station module to acquire the management command for railway station interlock- ing, and send it to the communication slave station module. The communication slave station module manages the railway station interlocking according to the management command, and drives the signal acquisition module to acquire the railway station inter- locking signal. All the signals coming from the communication slave station module and signal acquisition module are transmitted to the communication master module for the unified analysis, optimization and early warning. The signal transmission loss func- tion and system memory optimization language are designed in the third part of this paper. The experimental results show that the designed system can improve the safety of railway transportation and throughout capacity of railway station.
