摘要
高速综合检测列车是保证高速铁路安全高效运营的重要手段,其检测效率与资源分配的合理性尤为关键。为提升检测效率,降低检测人员工作强度,提出一种基于权重映射的多层网络分割算法,以实现高速铁路网络的均衡划分。为解决多层网络分割算法破坏网络连通拓扑的问题,在既有的多层网络分割算法中引入权重映射策略,通过概化、分割、细化3个阶段将高速铁路网络图划分为均等分区。实验表明,该算法能有效将全国高速铁路网络完整均衡分割为若干检测分区,各区域里程差异控制在10%以内,显著降低检测人员工作强度与车底维护成本。相比于传统算法,本方法在保障网络拓扑连通性的同时,解决大规模路网分割效率低、边界割裂线路等问题,为动态检测计划的智能编制提供参考。
High speed comprehensive inspection train serves as an important tool to ensure the safe and efficient operation of high speed railways,and its inspection efficiency and the rationality of resource allocation are particularly critical.In order to improve the inspection efficiency and reduce the work intensity of inspection personnel,a multi-level network partition algorithm based on weight mapping was proposed,so as to realize the balanced division of high speed railway network.In order to solve the problem that the multi-level network partition algorithm destroys the network connectivity topology,the weight mapping strategy was introduced into the existing multi-level network partition algorithm,and the high speed railway network graph was divided into equal regions through three phases,such as generalization,partitioning,and refinement.The experiment shows that the algorithm can effectively divide the national high speed railway network into several inspection regions in a comprehensive and balanced manner.The mileage discrepancy between regions is controlled within 10%,significantly reducing the work intensity of inspection personnel and carriage maintenance costs.Compared to traditional algorithms,this method ensures network topology connectivity while addressing inefficiencies in large-scale railway network partition and issues of fragmented boundary lines,providing a reference for the intelligent formulation of dynamic inspection plans.
