DOUBLE REDUNDANT CONTROL SYSTEM FOR SWITCHING OF CROSSING-GATE LOWERING OPERATION

Title:

DOUBLE REDUNDANT CONTROL SYSTEM FOR SWITCHING OF CROSSING-GATE LOWERING OPERATION

Document Type and Number:

Japanese Patent JP2007313957

Kind Code:

A

Abstract:

To provide a control system that further improves safety of self-weight-lowering switching when disturbed during lowering operation of a crossing bar in a crossing gate than a conventional one.

A double redundant control system 1 is composed of a CPU 3, which executes control to a motor driving circuit 2 for operating the crossing bar, and an electric circuit 4 that achieves prescribed operation in the motor driving circuit 2 based on prescribed control by the CPU 3 even when some abnormalities occur in the prescribed control by the CPU 3 or in the prescribed operation in the motor driving circuit 2 based on the prescribed control by the CPU 3. It is possible to use a CR circuit as the electric circuit.
