Method for Synchronizing Optical Units of a Photoelectric Barrier and Light Curtain

摘要

The present invention relates to a method for synchronizing the optical units of a photoelectric barrier and to such a photoelectric barrier. The synchronization method comprises the steps of transmitting radiation forming a synchronization signal from a first optical sender of the first optical unit; controlling a plurality of the optical receivers of the at least one second optical unit to monitor whether the synchronization signal has been received and performing a synchronization step if the synchronization signal has been received. The method further performs the step of defining at least one of said plurality of optoelectronic components to be used for the synchronization step.

1. A method of synchronizing at least two optical units of a photoelectric barrier, said barrier monitoring a surveillance area and comprising at least one first optical unit and at least one second optical unit, each optical unit comprising a plurality of optoelectronic components with at least one optical sender, at least one optical receiver and a control element, said method comprising the steps of:
transmitting radiation forming a synchronization signal from a first optical sender of the first optical unit; controlling a plurality of the optical receivers of the at least one second optical unit to monitor whether the synchronization signal has been received; and performing a synchronization step when the synchronization signal has been received, wherein the method further performs the step of defining at least one of said plurality of optoelectronic components to be used for the synchronization step.
