The present invention relates to a "train wheel monitoring system and method" for monitoring the condition of a train wheel, and in particular, by taking an image (thermal image) of the temperature distribution of the wheel to detect the occurrence of scratches, the degree of scratches and wheel internal defects In case that it is determined that the operation of the train is difficult due to poor wheel condition, an alarm signal indicating this is generated. First, the wheel condition can be monitored even while the train is running. Second, the maintenance, repair and maintenance of the wheel are performed. In addition, it is possible to comprehensively perform management, and third, to prevent an accident due to poor wheel condition by notifying the wheel condition is extremely poor.

This is an improved invention that improves the train wheel scratch monitoring system and method of the Republic of Korea Patent Application No. 10-2008-0017015 which is my prior application.

As is well known, trains are a mass transportation mode that requires high safety first, and many devices are continuously developed to ensure the safety of trains and passengers, improve riding comfort, improve driving efficiency, and improve driving convenience. Has been.

Wheel scratches caused by friction between wheels and rails are factors that generate noise, reduce riding comfort, impair safety and reduce driving quality, and ensure safety by detecting wheel scratches and promptly repairing them. Wheel scratch detection devices have been continuously developed to improve ride comfort and improve driving quality.

Conventional devices for detecting scratches on train wheels are registered in Korean Patent Application No. 1992-0022338, "Scratch Extraction Device for Railway and Subway Wheels", Korean Patent Registration No. 10-0199692 As described in No. 10-0294725, "Automatic Scratch Extraction Device and Automatic Extraction Method of Railroad Vehicle Wheels", etc., the impact sound or vibration generated when the scratch portion of the wheel hits the rail was detected to detect whether the wheel scratches occurred. .

Republic of Korea Patent Application No. 10-2005-0092421 "train inspection apparatus" to take a wheel shape using a camera and moire pattern to restore the three-dimensional data, and then to detect the occurrence of scratches by comparing with the stored standard wheel data The method was presented.

However, the conventional wheel scratch detection methods for detecting the occurrence of a scratch by detecting impact sound or vibration, as well as the detection error occurs according to the installation position, the installation environment, and the degree of scratches, as well as the train in the train window (the inspection base) There is a problem that it is necessary to inspect the goods by receiving them, and the method of detecting the occurrence of scratches by restoring the 3D data requires the use of complicated mechanical equipment, and also makes it difficult to photograph the flange and the back surface of the wheel and to limit the inspection position. There were problems such as receiving.

The present invention is to solve the conventional problems as described above, as shown in Figure 2, a track system for photographing and transmitting the image of the rail temperature distribution after the wheel passing; Receives an image of the rail temperature distribution transmitted from the track system 1 and analyzes the temperature distribution of the received image to monitor whether the wheel is scratched and the degree of the scratch, and to monitor the database and to monitor the results of the database.

As shown in FIG. 3, the present invention of the present invention captures an image of the temperature distribution of the rail immediately after the wheel passes, and detects the temperature of the raised rail due to the collision between the scratch portion of the wheel and the rail, and whether or not a scratch occurs. If the train is difficult to operate due to the degree of abrasion while monitoring the degree and making a database, an alarm signal indicating this is generated to facilitate the maintenance, repair and management of the wheels.

In the figure, reference numeral 2a denotes a wheel image, 2b denotes an abnormal high temperature point, and 2c denotes a rail image.

However, the above-described invention of the applicant's own application can detect an abnormal high temperature point of the rail and detect whether a scratch has occurred after taking an image of the rail temperature distribution immediately after the wheel passes, and therefore, the defect inside the wheel can be detected. In the case where two or more wheels are installed in a row, it is difficult to determine in which wheel the detected scratches occur, and in the case of very small scratches, the temperature rise is small, and the elevated temperature easily reaches the ambient temperature. There was a problem that it is difficult to detect due to dilution.

An object of the present invention is to solve the above-mentioned conventional problems, in particular, by taking an image (thermal image) of the temperature distribution of the wheels of the train running on the track, whether or not scratches occur, the degree of scratches, cracks, etc. While detecting and monitoring and internalizing a wheel internal defect of the wheel, an alarm signal indicating that it is difficult to operate a train due to a poor wheel condition may be generated. First, a wheel condition may be detected during train operation. It is possible to easily monitor the wheels of all vehicles operating the route, and thirdly, it is possible to comprehensively perform the maintenance, repair and management of the wheels, and fourthly, to prevent accidents due to poor wheel condition. It is to provide a "train wheel monitoring system and method" that can be.

In other words, by taking images of the temperature distribution of the wheel of the train in operation using a thermal imaging camera to analyze and display the occurrence of scratches, the degree of scratches (size of scratches), internal defects, etc. It is to solve the problems caused by poor wheel condition by enabling comprehensive real-time monitoring of the maintenance, repair, and management of the wheels of the vehicle.

That is, it is preferable to use a wheel sensor to detect a wheel by using a wheel sensor or a magnetic sensor known to detect a wheel, or a sensor that detects a train wheel in contact and non-contact such as an ultrasonic sensor, an optical sensor, or a proximity sensor.

The thermal imaging camera of the image capturing unit is preferably composed of an infrared camera for photographing the temperature of the subject in different colors.

An image of the wheel temperature distribution photographed by the image capturing unit may be a moving image or a still image.

When taking a still image of the wheel temperature distribution in the image pickup unit, it is characterized in that to take more than two times in consideration of the train speed to obtain an image for both the wheel surface and the side.

For example, 25% of the entire surface (wheel outer diameter) is part of the surface (including side) taken by the thermal imaging camera due to the attachments (wheel axle, shock absorber, etc.) and the location of the thermal imaging camera. In the case of 90 degree shooting angle, at least 4 still images are taken so that the entire face and side can be taken.

The image processor may detect an abnormal high temperature point or an abnormal low temperature point of the wheel by analyzing an image of a wheel temperature distribution.

The image processing unit divides the image of the wheel temperature distribution into an answer surface part, a side part, and a flange part to determine an abnormal high temperature point occurring at the answer surface part as a scratch occurrence point, and an abnormal high temperature point or abnormality generated on the side part and the flange. The low temperature point is determined as an internal defect of the wheel.

The image processor detects a wheel by comparing each pixel of a thermal image (image of a rail temperature distribution) that changes color according to temperature, and divides the wheel into a step portion, a side portion, and a flange, and then forms the wheel. The temperature of the wheel is detected from the color of each pixel, and when the temperature difference is greater than or equal to a predetermined value, the abnormal high temperature point is determined as the abnormal low temperature point.

The abnormal high temperature point indicates that a scratch has occurred on the wheel to a point where the temperature has risen due to the scratch on the wheel tread.

In other words, if the surface of the wheel does not have scratches, the temperature of the wheels raised by the train operation should be spread evenly.However, if the surface of the wheels is scratched, the wheel temperature at the scratch point may be affected by the collision between the scratch and the rail. An abnormal high temperature point is generated to be higher, and the abnormal high temperature point is detected to determine whether or not a scratch occurs.

Similarly, if a defect such as a crack occurs in the wheel, heat transfer is uneven, resulting in an abnormal high temperature point or an abnormal low temperature point on the wheel. The abnormal high temperature point or abnormal low temperature point is determined as an internal defect occurrence point.

At this time, the range in which the abnormal high temperature point generated on the wheel step surface is wide and the temperature of the abnormal high temperature point is higher than the temperature of the surrounding rail, it is determined that the degree of abrasion is severe.

Similarly, the wider the range of abnormal high temperature points or abnormal low temperature points occurring on the side of the wheel and the higher the temperature difference with the surroundings, the greater the internal defects.

As wheels accumulate heat due to scratches or internal defects during train operation, there is a large temperature difference between scratches and internal defects.
