Description

{Semiconductor switching system using Non-Contact control relay unit for electric point machine}

The present invention relates to an electric line switching device including a contactless control relay.

Recently, as the proportion of railways in the industry has gradually increased, the management of components in railways has emerged as a more important issue for the safe operation of trains.

In particular, the track switcher, which is one of the components of the railroad, is an important component that safely changes the direction of the train, and abnormal situations and breakdowns caused by the aging of the track switcher are large accidents such as derailment from small accidents of train operation delay. It is very important to predict the failure of the line changer early and to determine the appropriate replacement timing because it can cause a problem.

It is a very important issue to detect the failure early because a breakdown of the track switch can cause a major accident such as a train derailment.

For example, according to the signal equipment failure status from 2000 to 2010, line switch failures accounted for 119 out of 447 railway signal equipment failure frequencies, accounting for 27% of the total signal equipment failure. There is a problem that requires manpower and time.

In addition, accidents often occur due to carelessness during work, and there is a difficulty in carrying out maintenance and repair work at night after the train is running. Therefore, it is very important to predict the failure of the line switch and automatically detect whether it is time to replace it.

It takes a lot of manpower and time to diagnose the failure of the track switch, and there is a difficulty as maintenance and repair work is carried out at night when the train operation time is over. In addition, the track changer is replaced according to the replacement guidelines such as the operating period (more than 10 years) or the number of conversions (more than 100,000 times), and the degree of deterioration depends on the surrounding environment (weather, train speed, etc.) As they are different, it is not efficient to replace the line switch according to the replacement instructions.

Recently, researches have been published to detect early obstacles in the transition period. For example, in the prior literature "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, In 30(1), pp. 81-92.", Asada et al. used DWT (Discrete Wavelet Transform; Discrete Wavelet Transform) and SVM (Support Vector Machine) to apply it to the current data of the line converter. We proposed a method to detect the failure of In this study, there is a limitation in detecting a fault using current data that artificially generated a fault 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. performed Uniform Scaling. Using this, a method for detecting the failure of the line switcher was proposed by applying it to the current data of the line switcher. In this study, in this study, normal and abnormal are classified as a method of solving problems with different lengths of time series current data using Uniform Scaling, but normal and abnormal are not classified when there is a nonlinear difference in the pattern of current data. There is a limit to not being able to.

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." In order to detect the pattern, a method of detecting an abnormal current pattern using DTW (Dynamic Time Warping) has been proposed. In this document, there is a limitation in that it is difficult to classify subtle differences caused by aging of current data.
