Abstract
A method of securing at least one hazard zone comprising a hazardous machine is provided, wherein objects are detected in an environment of the hazard zone from measured data of at least one 3D sensor, and wherein a safety directed reaction of the machine takes place on an impending danger. A switch is made to at least one new hazard zone to be activated during the operation of the machine and a check is made whether the new hazard zone to be secured is free of objects.
Claims11
A method of securing at least one hazard zone of a hazardous machine, comprising:
- detecting objects in an environment of the at least one hazard zone from measured data of at least one 3D sensor, wherein a safety directed reaction of the machine takes place on an impending danger;
- generating an activation request on the at least one 3D sensor for switching over of hazard zones;
- checking whether new hazard zones to be secured are free of objects;
- reporting an object status on the new hazard zones;
- and
- performing a switchover to at least one of the new hazard zones to be secured during the operation of the machine, the at least one of the new hazard zones being free of objects.
A 3D sensor for monitoring an environment of at least one hazard zone comprising a hazardous machine, wherein the 3D sensor has at least one image sensor for detecting three-dimensional image data and a control and evaluation unit that is configured to detect objects in the environment of the at least one hazard zone with reference to the three-dimensional image data,
- wherein at least two configuration sets of hazard zones are stored in a memory of the 3D sensor and the control and evaluation unit is further configured to:
- generate an activation request on the 3D sensor for switching over of the hazard zones;
- check whether new hazard zones to be secured are free of objects;
- report an object status on the new hazard zones;
- and
- perform a switchover to at least one of the new hazard zones to be secured, the at least one of the new hazard zones being free of objects.
