Motor train unit running fault dynamic image detecting system and method

Abstract

The invention discloses a motor train unit running fault dynamic image detecting system and method. The motor train unit running fault dynamic image detecting method comprises the following steps of monitoring and acquiring incoming train information, processing the incoming train information, judging train passing conditions according to the incoming train information and acquiring train passing information; acquiring image information of passing motor train units when trains start to pass by according to the train passing conditions, identifying and processing the image information according to the train passing information, classifying the image information in an agreed means, storing the image information and uploading the image information to a database for fault analysis; and stopping information acquisition when train passing is finished. By means of the motor train unit running fault dynamic image detecting method and system, non-manual on-line fault detection can be performed on motor train units running at a high speed. The fault detection accuracy and efficiency can be further improved.

Description

technical field [0001] The invention relates to the technical field of on-line maintenance of multiple train sets, in particular to a dynamic image detection system and method for running faults of multiple train sets. Background technique [0002] At present, the high-speed EMUs developed by my country indicate that China's railways have entered the world's advanced railway ranks, such as EMUs with a high degree of electromechanical integration, which integrates cutting-edge technologies in the fields of machinery, electronics, metallurgy, and non-metallic materials. However, for EMUs operating at high speeds, any slight fault may cause a major accident. The traditional human-based inspection method is likely to cause missed inspections, and it is difficult to guarantee the quality and efficiency of inspection operations. Increased the probability of potential safety hazards in the operation of EMUs. Therefore, it is very important to improve the quality of EMU inspection ...

Problems solved by technology

[0003] For example, for the inspection of EMUs, since the scope of routine passenger train inspection does not include EMUs, the operation safety of EMUs cannot be effectively guaranteed. Therefore, this will lead to continuous and uninterrupted operation of EMUs for a long time , which is a great test for the safe operation of the EMU

In addition, the structure of the EMU is complex, and there are many parts for inspection in the warehouse, which may easily cause missed inspections and bring safety hazards to the operation of the EMU.

[0004] In addition, there are two important technical reasons that affect the safety inspection of EMUs: First, at the current stage, the maintenance of EMUs mainly relies on people, and the maintenance personnel are still in the groping stage for the understanding of the fault forms and laws of EMUs. It is also easy to cause missed inspections, and the quality of inspections is greatly affected by the sense of responsibility, mentality and physical condition of the maintenance personnel, and it is difficult to maintain the quality of work for a long time; In addition, the faults that occur during the operation of the EMU cannot rely on manual online detection. After the EMU is put into storage, when the maintenance personnel go online to work, since the EMU has completely stopped, the faults that can only occur during operation (such as the motor Heat, brake disc abnormality, coupling abnormality, gearbox abnormality, etc.) are difficult to find, and such faults are all faults that endanger driving safety, so it is very important to ensure that such hidden faults can be found
