Monitoring device for safety-critical unit, particularly conveyer of conveyer system, has first video sensor unit, which is adapted to generate first image as representation formed from line by first monitoring area of safety-critical unit

摘要

The monitoring device (10) has a first video sensor unit (12), which is adapted to generate a first image as a representation formed from a line by a first monitoring area of a safety-critical unit. A first evaluation unit (20) has a unit for determining a sub-area on an image section that shows the first monitoring area of the safety-critical unit. A comparison unit is adapted to compare the sum with a reference value. An independent claim is included for a method for monitoring a safety-critical unit.
