摘要
当前铁路新修和改造线路的增多,使无线调车机车信号和监控系统(STP)车载站场数据换装频率成倍增加。为降低车载维护人员工作量,解决STP系统车载站场数据换装及管理存在的问题,提出在不增加硬件的情况下,通过优化数据结构、断点续传、数据压缩、安全通信协议等方法,利用既有车地无线通道,实现站内和机务段内车载站场数据的无线换装、自动销记和版本卡控,并通过STP系统的上位机完成换装过程的实时跟踪和过程记录。
At present,along with the increasing number of newly-built and upgraded railways,the replacement frequency of on-board STP station-yard data has increased sharply.In order to reduce the workload of on-board maintenance personnel and solve the problems related to the on-board STP station-yard data replacement and management,this paper proposes to achieve wireless replacement of on-board station-yard data in station and locomotive depot,automatic write-off and version control through optimization of data structure,breakpoint transmission,data compression,and secure communication protocol,etc.,and complete the real-time tracking and process recording of the replacement by the master computer of STP system.
