Abstract
The current signalling system in a machine room has a complex configuration, as
additional devices like the automatic train protection (ATP) controllers have
gradually been installed to raise the safety level. At the same time, these devices
and interlocking interact complexly with each other. This complex configuration
consequently causes complexity in designing, installing and maintaining the
system, and decreases the availability of it. To solve these issues, development of
the integrated signal control system, \“Logical Controller” (LC) is in progress. LC
is a set of high-performance computers integrating the logical devices in a
machine room. Toward the practical use of the LC, there are two major
challenges: construction and verification of the integrated control logic, and
minimization of the range affected in partial software upgrading or partial
malfunction. In this paper, the outline of the LC is described and the techniques
for solving the above-mentioned challenges are discussed.
Keywords: safety, reliability, control logic, integration, practical use,
maintenance.
