The invention relates to a reliability analysis method and device for urban rail equipment, equipment and a storage medium. The method comprises the following steps: acquiring historical fault data of to-be-analyzed urban rail equipment; analyzing the historical fault data to determine whether the failure rate of the urban rail equipment to be analyzed changes along with time; if not, determining a reliability index of the to-be-analyzed urban rail equipment through index distribution; if yes, the reliability index of the urban rail equipment to be analyzed is determined through Weibull distribution. According to the method, the matched distribution model is selected based on the fault distribution characteristics of the to-be-analyzed urban rail equipment to perform reliability analysis on the to-be-analyzed urban rail equipment, so that the obtained reliability index better conforms to the actual operation condition of the to-be-analyzed urban rail equipment, and the to-be-analyzed urban rail equipment can be more effectively maintained; according to the technical scheme, faults can be found and processed in time, the safety performance of the to-be-analyzed urban rail equipment is improved, over-repair or under-repair of the to-be-analyzed urban rail equipment in the service stage can be avoided, and the maintenance cost is reduced.
Description
technical field [0001] The present application relates to the technical field of urban rail transit, in particular to a reliability analysis method, device, equipment and storage medium of urban rail equipment. Background technique [0002] As the operating mileage of urban rail transit continues to grow and the scale of the line network continues to expand, the safe operation of urban rail transit equipment directly affects operational efficiency and operational safety. [0003] In the traditional maintenance business, in order to prevent and reduce accidents and ensure the smooth and normal operation of urban rail transit equipment, such equipment is usually maintained according to a fixed maintenance cycle. However, the above-mentioned methods may cause over-repair of the equipment during the service phase, resulting in an increase in equipment maintenance costs, and may also cause under-repair of the equipment, resulting in a decrease in its reliability and safety.
