Abstract

The invention relates to a method for setting up a surveillance zone ( 4 ) of a location system for acquiring the position of at least one movable object within a goods logistics facility ( 2 ), a method for operating such a location system, and a location system for a goods logistics facility ( 2 ). The method for setting up the surveillance zone ( 4 ) includes the following steps of the method: Moving a zone setting up apparatus ( 50 ) along a closed movement path ( 6 ) within an acquisition range and simultaneously capturing at least three different path positions ( 7 ) of the zone setting up apparatus ( 50 ), determining a route of an outer boundary ( 5 ) of the surveillance zone ( 4 ) to be set up based on the path positions ( 7 ) acquired, and defining an area enclosed by the outer boundary ( 5 ) as a surveillance zone ( 4 ).

First claim

What is claimed is:

1. A location system for a goods logistics facility, the location system comprising:
a zone setting up apparatus; and
at least two anchor nodes;
wherein the location system is configured to determine a route of an outer boundary of a surveillance zone to be set up and to define an area enclosed by the outer boundary as a surveillance zone by moving the zone setting up apparatus within an acquisition range of the location system along a closed movement path and by simultaneous acquisition of at least three different path positions of the zone setting up apparatus,
wherein the location system is further configured to establish, based on position acquisition, whether a movable object equipped with a transmitter and receiver apparatus is located inside or outside the surveillance zone,
wherein the at least two anchor nodes are configured to define reference points within a coordinate system of the location system,
wherein the location system is configured to perform a distance measurement by signal transmissions between the zone setting up apparatus and the at least two anchor nodes for the acquisition of the at least three different path positions,
wherein the location system is configured to generate a message when the movable object is located inside the surveillance zone and to make the message available to a unit outside thereof or to transmit the message to the unit outside thereof,
wherein the location system is configured such that the surveillance zone is a zone with a speed limit, and
wherein the location system is configured to transmit a warning message to a control system of the movable object when the movable object enters the inside the surveillance zone and the movable object is an industrial truck.

2. The location system according to claim 1 , wherein the location system is configured to perform signal transmissions between the at least two anchor nodes and the zone setting up apparatus and/or between the at least two anchor nodes and the transmitter and receiver apparatus using ultra-wideband technology.

3. The location system according to claim 1 , wherein the location system is configured to start the acquisition of the at least three different path positions by a first user input, and to complete the acquisition of the at least three different path positions by a second user input, and wherein the first and second user inputs take place on the zone setting up apparatus.

4. The location system according to claim 1 , wherein the warning message transmitted to the control system of the industrial truck is configured to limit the speed of the industrial truck inside the surveillance zone.

5. The location system according to claim 1 , wherein the warning message transmitted to the control system of the industrial truck is configured to be displayed on a display of the industrial truck to indicate that the industrial truck is located within the surveillance zone with the speed limit.

6. A location system for a goods logistics facility, the location system comprising:
a zone setting up apparatus; and
at least two anchor nodes;
wherein the location system is configured to determine a route of an outer boundary of a surveillance zone to be set up and to define an area enclosed by the outer boundary as a surveillance zone by moving the zone setting up apparatus within an acquisition range of the location system along a closed movement path and by simultaneous acquisition of at least three different path positions of the zone setting up apparatus,
wherein the location system is further configured to establish, based on position acquisition, whether a movable object equipped with a transmitter and receiver apparatus is located inside or outside the surveillance zone,
wherein the at least two anchor nodes are configured to define reference points within a coordinate system of the location system,
wherein the location system is configured to perform a distance measurement by signal transmissions between the zone setting up apparatus and the at least two anchor nodes for the acquisition of the at least three different path positions,
wherein the location system is configured to generate a message when the movable object is located inside the surveillance zone and to make the message available to a unit outside thereof or to transmit the message to the unit outside thereof,
wherein the location system is configured such that the surveillance zone is a danger zone,
wherein the location system is configured to transmit a warning message to a control system of the movable object when the movable object enters the inside the surveillance zone,
(ii) the movable object is an industrial truck, and
(iii) another industrial truck is also present in the danger zone, and
wherein the warning message is transmitted to limit the speed of the industrial truck in the danger zone.

7. The location system according to claim 6 , wherein the warning message transmitted to the control system of the industrial truck is configured to be displayed on a display of the industrial truck, is configured to be an acoustic signal, or is configured to be a haptic signal in the form of a vibration of a part of the industrial truck.

8. A location system for a goods logistics facility, the location system comprising:
a zone setting up apparatus; and
at least two anchor nodes;
wherein the location system is configured to determine a route of an outer boundary of a surveillance zone to be set up and to define an area enclosed by the outer boundary as a surveillance zone by moving the zone setting up apparatus within an acquisition range of the location system along a closed movement path and by simultaneous acquisition of at least three different path positions of the zone setting up apparatus,
wherein the location system is further configured to establish, based on position acquisition, whether a movable object equipped with a transmitter and receiver apparatus is located inside or outside the surveillance zone,
wherein the at least two anchor nodes are configured to define reference points within a coordinate system of the location system,
wherein the location system is configured to perform a distance measurement by signal transmissions between the zone setting up apparatus and the at least two anchor nodes for the acquisition of the at least three different path positions,
wherein the location system is configured to generate a message when the movable object is located inside the surveillance zone and to make the message available to a unit outside thereof or to transmit the message to the unit outside thereof,
wherein the location system is configured such that the surveillance zone is a zone with limited access,
wherein the location system is configured to transmit a warning message to a control system of the movable object or to supervisory staff when the movable object enters the inside the surveillance zone,
(ii) the movable object is an industrial truck, and
(iii) the industrial truck does not fulfill access requirements for the zone with limited access.
