The invention proposes a railway rail damage detection method and device, which are used to calculate the detection ability of a flaw detection vehicle for various damages, wherein the railway rail damage detection method includes: obtaining the original data of railway rail damage; Method and machine learning method, establish detection probability models of different damage types; according to the original data of the railway rail damage, use the MLE maximum probability estimation method to determine the fitting parameters in the detection probability model; according to the determined different The detection probability model of the damage type and the current speed of the rail flaw detection vehicle or the detection probability of the set damage type determine the detection probability of different damage types or the speed range of the rail flaw detection vehicle.
Description
technical field [0001] The invention relates to the field of rail flaw detection, in particular to a method and device for rail flaw detection. Background technique [0002] In my country's rail flaw detection system, there are two forms of rail flaw detection vehicle detection and rail flaw detector detection. The rail flaw detection vehicle has fast flaw detection speed and strong adaptability, but the results of flaw detection operations require manual on-site review to determine the existence and size of damage. The rail flaw detector has high flaw detection sensitivity, but low speed and poor efficiency. With the rapid development of railway transportation, rail flaw detection vehicles have undertaken more and more flaw detection and detection tasks, especially on high-speed railway lines and plateau lines. Due to the long interval mileage and harsh environment, manual flaw detection operations are difficult, and flaw detection vehicles are mainly used. Conduct rail f...
