Development of an Integrated Logical Controller

The reduction of metallic cables, improvement in installation and simplification of operation tests by replacing voltage control with information control through an optical fiber network have been realized through the previous development of an Internet protocol (IP) Network-based Signal Control System. However, according to functions such as those for interlocking equipment and the automatic train protection (ATP) controller, the logical devices to determine control information of signal devices still exist separately, and they remain complex. Complicated design, installation and maintenance of the system result from this complex configuration, as well as a decrease in its availability. Therefore, a set of high-performance computers integrating logical devices in a signal house was developed to solve these issues in the form of an Integrated Logical Controller (LC), and prototypes were produced for that. The prototypes were temporarily installed to existing stations, and the adequacy of the control logic was verified for practical use. In addition, issues in terms of its actual use were clarified and the methods to solve them were considered, prior to developing the practical system.
