WTB통신 Message Data 활용방안에 관한 연구

In high-speed railway and electric motor vehicle the efficiency and reliability of communication system which controls signals for control and diagnostics have an influence on entire system"s performance. That"s why diagnostics and error detecting functions of communication systems are becoming essential part. WTB communication is responsible for communication between vehicles and keeps 3 different data types such as Process Data, Message Data, Supervisory Data to manage distributed devices efficiently from a master node. Message Data is sent over network aperiodically using Event-polling method and users can use this message to monitor the status of slave"s communication. This paper presents how to utilize Message Data which can be requested aperiodically and define data used for diagnosis of slave"s communication status.
