Abstract: This paper presents a distance-based algorithm for site data processing based on long-chain hashing algorithm by analyzing the difference of railway signal products such as TCC, RBC and TSRS software for railway line data processing. It not only makes the line data configuration flexible and unified by providing data configuration users with an interface to define their own configuration rules, but also makes development users get points comparison, scope judgment, distance calculation of line data without in consideration to line data configuration rules by providing the calculation interface of relative and absolute distance of any point on the railway line, so as to solve the problem that the current line data processing logic cannot be universal due to the different line data configuration rules of various products. The paper also puts forward further prospects and plans for the subsequent application of this algorithm in line data processing.
