레일절손 감시 시스템에 대한 연구

Railway is used more than other public transportation since it has good punctuality and safety and securing safety is of importance as it is a mass transportation. But, train derailment due to the broken rail as a factor obstructing the safety of trains. Since a minute defect(crack) is often changed to breaking of the rail , we can identify the condition of occupation of trains by the detection of track shunt in existing fixed block track circuit when broken rail occurs. However, since recent CBTC(Communication Based on Train Control) systems is moving block trackless , it is impossible to detect broken rail. Thus, this paper examined domestic and abroad methods of detecting broken rail , developed and tested a monitoring system for rail breaks using optical fiber method, and proved it didn't have any problems to be applied to the field of railway.
