Abstract (en)
[origin: WO2006061346A1] The invention relates to a speed monitoring method in an automation system (4) for a conveyor installation (2), particularly for a pit. A speed monitoring method is provided that eliminates the need for detection elements for determining position that are arranged along the path of conveyance. An actual path value (X<SUB>a</SUB>) and an actual speed value (v<SUB>a</SUB>) are determined by means of at least one pulse counter (18, 20, 22). The actual path value (X<SUB>a</SUB>) is used for reading out a speed limiting value (v<SUB>2</SUB>) from a data table, which is stored in the automation system (4) and which represents a stepped limiting value curve (46) and for comparing the actual speed value (v<SUB>a</SUB>) with the read out speed limiting value (v<SUB>2</SUB>).
