The Network Implementation on Data Communication of TCMS in case of multiple configuration of EMU(Electric Multiple Unit)

전동차의 중련연결시 TCMS장치의 데이터 통신에 관한 네트워크 구현

The train configuration is based on one unit like basic 4 cars to multiple unit operation. Each unit has unique node such as train formation number. Some equipments(TC, CC) of TCMS are connected to the master TC through the LonWorks network. When the train is consist of multiple unit, TCMS has to implement quick network for data communication overall train. But a variable time delay is generated when it is performed communication with point to point type using train formation number. In this paper we propose new method to know the node information of adjacent unit. that is to add digital input signals notifying cab direction at any cabin. Also, we provide the optimized screen design that all collected information via network is displayed by each unit.
