摘要: 针对铁路信号产品无线闭塞中心、临时限速服务器、列控中心软件对于长链的处理存在的差异进行分析,提出对于长链的一种散列处理算法,兼容目前使用的两种长链规范标准,力求配置最少的信息,得到对于长链计算所需的各种关键参数,以提供给研发、测试开发所需对于长链处理的公共处理接口,使开发人员不再处理长链的计算,解决数据配置人员由于各产品处理长链逻辑的差异而导致的长链数据配置错误率高、影响既有数据大的问题。也将对此算法在线路数据处理的后续应用,提出进一步的展望和规划。

Abstract: The paper presents a long-flag hash algorithm in compliance with two applicable long-flag standards by analyzing long-flag process differences in railway signal products of RBC, TSRS and TCC. The algorithm aims at obtaining all key parameters with the configuration of the least amount of site data, in order to facilitate long-flag calculation to free railway product developers from handling long-flag processes. When persons in charge of the configuration of site data set long-flag site data with this algorithm, the high error rate and big impact on existing site data will be reduced (the problems are caused by the differences in long-flag logic processes of various products). The paper also proposes further applications of the algorithm in site data processing.
