Problems solved by technology
[0003] The traditional planned maintenance mode stipulates a unified maintenance cycle, but does not fully consider the actual use of each component
When the planned maintenance time of a certain component is about to arrive or when the component has just been overhauled, other components also have abnormalities and need to be overhauled, which may lead to high-frequency and unnecessary repetitive operations in a short period of time during the maintenance operation. Reduced man-hour utilization and increased labor costs

Embodiment Construction
[0053] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.
[0054] This embodiment provides an intelligent maintenance method for rail transit vehicles, such as figure 1 As shown, the main flow of the method is described as follows (steps S101-S106):
[0055]Step S101: According to historical data and current operating data, predict the predicted time when the component to be repaired fails.
[0056] In this embodiment, the historical data includes the historical operation data and the time of failure of the parts to be repaired, and the historical data is analyzed. If whenever a certain operation data occurs, the parts to be repaired are about to break down, and the operation data is defined as For the early warni...

The invention relates to an intelligent maintenance method, device, and equipment for a rail transit vehicle, and belongs to the technical field of rail transit vehicle maintenance. The method comprises the following steps: predicting prediction time when a to-be-repaired part breaks down according to historical data and current operation data; according to a pre-established repair chain, determining the association degree between the to-be-repaired component and associated components, wherein the associated components refer to components associated with the to-be-repaired component; according to the prediction time, the association degree and existing repair process data, determining repair time of the to-be-repaired component, wherein the existing repair process data comprises planned repair time of the associated components; according to the existing repair process data, determining a repair cost for repairing the to-be-repaired component and a replacement cost for replacing the to-be-repaired component; according to the repair cost and the replacement cost, determining a repair mode of the to-be-repaired component, wherein the repair mode comprises repair and replacement; making a repair plan according to the repair mode and the repair time. The invention has the effect of reasonably arranging a repair plan.
Description
technical field [0001] The present application relates to the technical field of rail transit vehicle maintenance, in particular to a rail transit vehicle intelligent maintenance method, device and equipment. Background technique [0002] For various components of rail transit vehicles, especially the running parts such as bogies, bearing boxes and bearings, certain damages will occur with the operation of rail transit vehicles, which may cause failures. Therefore, during the operation of rail transit vehicles, Regular maintenance of rail transit vehicles is an important measure to ensure the safety of personnel. [0003] The traditional planned maintenance mode stipulates a unified maintenance cycle, but does not fully consider the actual use of each component. When the planned maintenance time of a certain component is about to arrive or when the component has just been overhauled, other components also have abnormalities and need to be overhauled, which may lead to high-...
