分散自律调度集中系统中车次追踪算法的研究

Study on train number logical tracing algorithm in Decentralized Self-regulated CTC System

车次追踪主要包括原始车次号的获取、逻辑追踪和定点校核3个方面。对于客车的原始车次号采用列车运行调整计划的车次顺序进行匹配;对于货车的原始车次号,通过始发车站货票管理系统获得。逻辑追踪的基本原理是同一时刻同一地点有且只有一列列车在运行或者停车,其关键技术就是依据列车运行的情况、当前时刻、当前地点来自动推算当前运行或者停车的列车的车次号。定点校核则是采用其他第3方系统获得的车次号有选择地对追踪结果进行校核。当原始车次号、逻辑追踪车次号和校核车次号三者一致时,任取其一作为正确的车次号;否则报警,由人工介入干预,得到正确的车次号。

Train number logical tracing algorithm was included acquiring to original train number, logically tracing and regularly checking. Facing with passenger trains, the matching of original numbers and the trains were relied on the trains operation rescheduling sequence. Facing with freight trains, the matching was relied on the data from freight invoice system of start station. The principal of logical tracing was at a certain time, there was no more than one train which was passing by or halting at certain position on the line. The key technique was to automatically calculate the train＇s number according to its operation status, its position and the time. Regularly checking was to check the tracing results with the train numbers provided by other systems. When the original train number, the logical tracing train number and the checking train number were identical, any of them could be used as the true train number; otherwise, the System was alarmed, and manual operation was involved to provide the true train number.
