Railway Signal Computer Interlocking System.pdf

1) System Structure

The Rail signal computer interlocking system is developed to match railway transportation development. The system is structured as 2x2 offering complete functions and reasonable structure.

Star topology is employed for network communication and information is transmitted by fiber optic cable.

The system is divided into three layers: the 1st being the monitoring and control layer, displaying the information of system control process and input system control commands; the 2nd is the interlocking logic processing layer, processing the signal interlocking operation; the 3rd is the collection layer, collecting and controlling the state information of the field devices in real time. The industrial Ethernet switch is employed for the communication network and data transmission to ensure safe, true and real-time signal device state and control information.

2) Network Requirements

Industrial Ethernet ring network of redundant 2x2 structure ensures security and reliability.
Complies with IEC61000 level 4.

3) Product Application

SICOM3024/SICOM3048/KIEN3024 are applied in the system for transparent transmission.
