Problems solved by technology

However, on the one hand, the probability of downtime of many devices is very low, and may not be several times a year. Therefore, the online collection of such data takes a long time
On the other hand, many industrial sites do not have a complete equipment data acquisition system, or even if there are some systems such as SCADA, they are more likely to complete real-time status monitoring. For the status data of equipment operation, the storage time is short and there is a lack of equipment data. Long-term storage makes it difficult to maintain transportation equipment and facilities

Abstract

The invention discloses a method and system for detecting and maintaining the state of rail transit equipment, wherein the method includes the following steps: acquiring the fault condition of the equipment or each component and the influencing factors affecting its service life, simulating the application scene under the influence of the influencing factors and obtaining the Based on the full life cycle data to form a full life cycle database, establish a dynamic model based on the full life cycle database, analyze and collect the main influencing factors and characteristics that affect the current equipment or component failures, hidden dangers, and service life, and receive the main influencing factors and characteristics To obtain the operating status data, analyze the operating status data and judge whether there is a potential fault, perform fault prediction and fault diagnosis on the equipment or each component, generate a maintenance plan according to the fault analysis result and send it to the terminal, and then establish a life database for the detected object. The operation data is obtained through monitoring, and the fault prediction and maintenance plan are made according to the operation data to ensure the normal operation of the transportation equipment.

Description

technical field [0001] The invention relates to the technical field of transportation equipment, in particular to a method and system for state detection and maintenance of rail transportation equipment. Background technique [0002] The repair schedule of the rail transit system mainly includes daily inspection, monthly inspection, erection repair, overhaul, etc. The main basis is the operating mileage and fault information of rail transit trains, and the service hidden danger information of related equipment and facilities, which is prone to excessive maintenance and Insufficient maintenance. Maintenance of equipment and facilities when there are hidden dangers of failure may easily cause delays and machine failures, which will affect the order of train operation. From the perspective of maintenance technology, the real-time information collection of vehicle-mounted sensors with redundant functions, complex networking, different interfaces, and cumbersome installation is ...
