  • According as railway signalling equipments are computerized recently, necessity of communication protocol for interface between these equipments is increasing, Therefore the research about communication protocol structure that is need according to computerization trend of these signalling goes, especially communication protocol structure for interface between LDTS(Local Data Transmission System) and EIS(Electronic Interlocking System). Analyzed existent protocols that is applied currently for interfaces between above two signalling for this research and also technology analysis of internal/external similar protocols and operator and maker's requirement. With these study finding plain in this paper, explained summary of communication protocol structure for interface between LDTS and EIS.

  • According to the computerization of railway signaling systems, the interface link between these signaling equipment is also replaced by digital communication channel, expecially communication link for interface between EIS and LDTS, but there are some problems in the present state of railway signaling. First of all, different communication protocol is applied to interface between above two signaling equipment 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 structure of designed communication protocol and the results of performance analyses are represented in this paper. It will be expected the increase of safety, reliability and efficiency of maintenance of signaling system by using of the designed communication protocol for railway signaling.
