基于数模双驱动的铁路客站票务设备健康状态评估模型

Health status evaluation model for railway passenger station ticketing equipment based on data and model dual driven

  • 摘要: 为及时掌握铁路客运车站(简称:客站)票务设备异常情况,评估其健康状态,采用数据驱动和模型驱动交互联动思想,提出了基于数模双驱动的票务设备健康状态评估模型。通过分析票务设备历史运行数据,构建以票务设备寿命预测值与实际值均方误差最小为核心的目标函数,利用优化算法求解其健康状态评价模型参数,实现对在役票务设备健康状态的评估。选取某铁路客站实名制核验闸机数据进行试验,结果表明,所提模型提高了客站票务设备健康状态评估的准确性,为客站票务设备精细化运行维护、预测性维修及主动运行维护提供了理论基础和决策依据。

     

    Abstract: In order to timely grasp the abnormal situation of ticketing equipment in railway passenger stations and evaluate their health status, this paper adopted the idea of data driven and model driven interactive linkage, and proposed a ticketing equipment health status evaluation model based on data and model dual driven. The paper analyzed the historical operating data of ticketing equipment, constructed an objective function with the minimum mean square error between the predicted and actual values of equipment life as the core, and used optimization algorithms to solve the parameters of the ticketing equipment health status evaluation model, implemented evaluation of the health status of in-service ticketing equipment and selected real name verification automatic fare gate data from a certain railway passenger station for testing. The results show that the proposed model improves the accuracy of the health status evaluation of the passenger station ticketing equipment, provides a theoretical basis and decision-making basis for the refined operation and maintenance, predictive maintenance, and active operation and maintenance of passenger station ticketing equipment.
