Abstract
Railway signaling systems are computerized equipment vital for the guarantee of
the safe running of trains. Because of the computerization of railway signaling
systems, the importance of a networking interface between these pieces of
equipment is increasing. Thus, it is important to have a reliable and safe
communication link between signaling equipment. Recently, network
technologies have been applied in a real-time industrial control system, and also
there are several studies applying computer network technology in vital control
systems such as railway signaling systems. To deploy these computer network
related studies in railway signaling systems, implementation costs, transmitted
reliability, safety assurance technique and compatibility etc, are considered. The
computer network protocol for railway signaling systems has an important
advantage over the widely used Ethernet in terms of deterministic characteristics.
In this paper, we propose computer network technology, especially the Ethernet,
for railway signaling systems. The computer network characteristics of real-time
industrial control systems and vital railway signaling systems are presented in
this paper. This algorithm presented is based on switched Ethernet technology
with a redundancy scheme. Also we demonstrate the experimental results of the
proposed network algorithm.
1 Introduction
Railway signaling systems are computerized vital systems for the guarantee of
the running trains safely which take charge of controlling train speed and
direction, especially preventing train collisions. Every signaling system plays
