A NEW DATA LINK PROTOCOL FOR RAILWAY SIGNALING SYSTEMS

초록

According to the computerization of railway signaling system, the interface link between these signaling equipment 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. First, different communication protocol is applied to interface between signaling although they have same functions. Next, the communication protocols currently used in the railway fields have some illogical parts such as a structure, a formation of byte, an error correction scheme and so on. To solve the matters, the new data link protocol for railway signaling systems is designed. In this paper, the structure of protocol and the results of performance analyses are represented. 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.
