Title:
SAFETY CONTROL DEVICE FOR AND SAFETY CONTROL SYSTEM OF RAILWAY
Document Type and Number:
Japanese Patent JP3668632
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enhance fail safe with a simple configuration.
SOLUTION: Input units 8A, 8B apply input signals from on-site devices to controllers 1A, 1B, respectively. The controllers 1A, 1B carry out operation based on the inputs of the signals to apply control signals to the on-site devices via output units 9A, 9B. In carrying out an input process, an operation process, and an input process, the controllers 1A, 1B carry out the collation of a self system and a mating system through common memories 16A, 16B. Disagreed data finds a fault to stop running. Healthy circuits 10A, 10B are circuits for applying signals indicating that the self system is in health. Applying signals indicating that any one of the systems is in abnormal applies no signals from the output units 9A, 9B.
