Abstract
Systems and methods for operation of a floor conveyor, the floor conveyor including a sensor device, the systems and methods include providing a predetermined detection zone outside at least a section of the circumference of the floor conveyor for detection of foreign objects positioned inside the predetermined detection zone, wherein the predetermined detection zone is arranged to end at a first predetermined distance from a predetermined object. The method further comprises extending the predetermined detection zone with a second predetermined distance within which the predetermined object is expected to be positioned. The method further comprises implementing security measures on the floor conveyor, if the predetermined object is not detected within the extended predetermined detection zone.
Claims20
A method for operation of a floor conveyor, the floor conveyor including a sensor device, the method comprising:
- via the sensor device, providing a detection zone outside at least a section of a circumference of the floor conveyor, wherein the detection zone is arranged to end at a first predetermined distance,
- extending the detection zone to end the detection zone at a second predetermined distance,
- via a control unit in communication with the sensor device, implementing a security measure on the floor conveyor if an object is not detected within the detection zone when the detection zone is extended to the second predetermined distance.
A floor conveyor comprising:
- a sensor device configured to generate a detection zone and to extend the detection zone from a first predetermined distance from the sensor device to a second predetermined distance from the sensor device;
- and
- a control unit in communication with the sensor device, the control unit to implement a security measure on the floor conveyor if an object is not detected within the detection zone when the detection zone extends to the second predetermined distance from the sensor device.
A floor conveyor comprising:
- a sensor device configured to:
- generate a detection zone having a first range that is to leave a gap between the detection zone and an object;
- and
- extend the detection zone to have a second range in which the object is to be within the detection zone;
- and
- a control unit in communication with the sensor device, the control unit to implement a security measure on the floor conveyor if the object is not detected within the detection zone when the detection zone is extended to have the second range.
