Comprehensive Evaluation Method and Practice of Equipment Health Grade on Signaling System Service Life Prolonging Requirements
Journal Title: Urban Mass Transit - Year 2024, Vol 27, Issue 10
Abstract
Objective Evaluation methods for conventional equipment health grade tend to be one-sided and limited in scope. There is a need to develop an evaluation method tailored to the stringent safety demands of signaling systems. The goal is to control the full lifecycle costs, extend the system longevity, and address the general pain point of financial constraints faced by most urban metro constructions at present. Method Starting with several conventional equipment health grade evaluation methods, a comprehensive evaluation model is constructed. The equipment historical performance is evaluated by annual average repair rate data, the equipment service life is evaluated by comparing the equipment designed theoretical lifespan with actual online service time, and current equipment conditions by field survey of actual working conditions and laboratory sampling test results. By integrating these multi-dimensional data points, a comprehensive evaluation method for signaling system safety equipment is developed. Result & Conclusion The practical application of this evaluation method, supported by data statistics and analysis, produces concrete evaluation conclusions and corresponding maintenance recommendations. This validates the feasibility of the comprehensive equipment health grade evaluation method. At the same time, the application of this method enables an in-depth inspection of signaling systems based on service life prolonging requirements, facilitates the formulation of targeted preventive maintenance measures, and proposes plans for future improvements in digitalization and intelligent technology.
