PERFORMANCE ANALYSIS OF DATA LINK PROTOCOL FOR RAILWAY SIGNALING

초록

According to the computerization of railway signaling system, the interface link between these signaling is also replaced by digital communication channel and the importance of this communication link is increased. However, there are some problems in the present state of railway signaling in Korea. First of all, different communication protocol is applied to interface between signaling although they have same functions. The other is that the communication protocol currently used in railway field has some unreasonable points such as structure, formation of byte, error correction scheme and etc. To solve these problems, the standard communication protocol for railway signaling is designed. The designed communication protocol for Korean railway signaling and the results of performance analyses are represented in this paper. It will be expected the increase of safety, reliability and the efficiency of maintenance of signaling system by using of the designed communication protocol for Korea railway signaling.
