SAFETY CONTROL DEVICE AND SAFETY CONTROL METHOD

Title:

SAFETY CONTROL DEVICE AND SAFETY CONTROL METHOD

Document Type and Number:

WIPO Patent Application WO/2012/104899

Kind Code:

A1

Abstract:

In order to enable safety control to be executed more rapidly in the event of malfunctions, an OS (100) has, in one part thereof, a partition scheduler (21) which selects and determines the time partition to be scheduled next in accordance with a scheduling pattern containing a TP1 which allocates an execution time to a safety monitoring programme, a TP2 which allocates an execution time to a normal control programme, and a TP3 which allocates an execution time to a safety control programme. A processor periodically operates the partition scheduler (21) by running the OS (100). The partition scheduler is activated in response to the detection of a malfunction by the safety monitoring programme being executed in the TP1 or the normal control programme being executed in the TP2, and carries out a switchover from the TP1 or the TP2 to the TP3 time partition.
