Description

Electric line transducer with contactless control relay and contactless circuit controller

The present invention relates to an electric line changer including a contactless control relay and a contactless circuit controller.

In recent years, as the proportion of railways in the industry has gradually increased, component management in railways has emerged as a more important issue for the safe operation of trains.

In particular, the track changer, one of the components of the railway, is an important component that safely changes the direction of the train. It is very important to predict the failure of the line switcher early and determine the appropriate replacement time.

Early detection of the failure is a very important issue because the failure of the track changer can cause major accidents such as train derailment.

For example, according to the status of signal device failures from 2000 to 2010, the breakdown of the track switcher was 119 out of 447 failures of the railroad signal device, accounting for 27% of the total failure of the signal device. There is a problem that requires manpower and time.

In addition, casualty accidents due to carelessness often occur during operation, and there is a difficulty in performing maintenance and repair work at night after the operation of the train is finished. Therefore, it is very important to predict the failure of the line changer and automatically detect the replacement time.

Diagnosing the fault of the track changer requires a lot of manpower and time, and there are difficulties because the maintenance and repair work is carried out at night when the operation time of the train is over. In addition, the track changer is replaced according to the replacement guidelines such as the operating period (more than 10 years) and the number of conversions (more than 100,000 times), and the degree of deterioration depends on the surrounding environment (weather, train speed, etc.) where the track changer is installed. It is not efficient to replace the line changer according to the replacement guidelines because they are different.

Recently, studies on early detection of faults in the line changer have been published. See, e.g., T. Asada, C. Roberts, and T. Koseki. (2013) An Algorithm for Improved Performance of Railway Condition Monitoring Equipment: Alternating-current Point Machine Case Study, Transportation Research Part C: Emerging Technologies, 30(1), pp. 81-92.", Asada et al. applied DWT (Discrete Wavelet Transform) and SVM (Support Vector Machine) to the current data of the line changer by applying it to the current data of the line changer. A method for detecting the failure of In this study, there is a limitation in detecting a failure using current data that artificially created a failure situation in a laboratory environment rather than actual current data.

On the other hand, in the conventional literature "M. Vileiniskis, R. Remenyte-Prescott, and D. Rama. (2015) A Fault Detection Method for Railway Point Systems, Journal of Rail and Rapid Transit, Online First.", Vileiniskis et al. A method for detecting the failure of the line changer by applying it to the line changer current data using the In this study, normal and abnormal were classified as a method to solve the problem of different lengths of time series current data using Uniform Scaling. There is a limit that cannot be.

In addition, in the conventional literature "H. Kim, J. Sa, Y. Chung, D. Park, and S. Yoon. (2016) Fault Diagnosis of Railway Point Machines using Dynamic Time Warping.", Kim et al. In order to detect the pattern, a method for detecting an abnormal current pattern using DTW (Dynamic Time Warping) has been proposed. In this document, there is a limit in that it is difficult to classify subtle differences caused by the aging of current data.
