Linux环境下区域计算机联锁系统设计

Design of regional computer interlocking system under linux environment

在利用原有系统进行区域控制时,受数据量过大的影响而无法进行控制命令处理,在区域铁路系统运营成本为15000~35000元的范围内存在列车事务处理性能较差的问题,因此,设计一种Linux环境下的区域计算机联锁系统。系统的硬件配置为轨道模块、道岔模块。其中轨道模块由MCU微控制器单元、调理电路单元、输入电路单元构成;道岔模块主要由逻辑防护单元、微控制器单元等构成。系统的软件构成包括进路选排模块、处理故障解锁模块、处理控制命令模块。其中进路选排模块能够实现预处理选岔与选岔、校核锁闭等功能;故障解锁模块的功能为对故障区段进行解锁;处理控制命令模块的功能为对处理函数进行选择。为证明该系统的列车事务处理性能较强,将原有系统与该系统进行对比实验,实验结果证明该系统的列车事务处理性能更好,实现了数据处理性能的提升。

when the original system is used for regional control,the control command cannot be processed due to the influence of too large amount of data,and the poor performance of train transaction processing exists in the range of 15000-35000 yuan of regional railway system operation cost.Therefore,a regional computer interlocking system under linux environment is designed.The hardware configuration of the system is track module and switch module.The track module is composed of MCU microcontroller unit,conditioning circuit unit and input circuit unit;the switch module is mainly composed of logic protection unit and micro controller unit.The software of the system consists of route selection module,fault unlocking module and control command module.Among them,the route selection and arrangement module can realize the functions of pretreatment,switch selection,check locking,etc;the function of the fault unlocking module is to unlock the fault section;the function of the processing control command module is to select the processing function.In order to prove that the train transaction processing performance of the system is strong,the original system is compared with the system.The experimental results show that the train transaction processing performance of the system is better,and the data processing performance is improved.
