Abstract

A method for operating a system with at least two floor processing devices includes detecting environmental features of an environment and generating an area map based on the detected features. The area map is divided into partial areas that are assigned to the floor processing devices so that each partial area is only processed by one of the floor processing devices. A movement route and a movement timespan of the floor processing device is detected and stored with the area map. Several partial areas are combined into partial area groups, and the partial areas are allocated to the floor processing devices based on the stored movement route and movement timespan so that a floor processing of a first partial area group by a first floor processing device takes place at essentially the same time as a floor processing of a second partial area group by a second floor processing device ends.

First claim

What is claimed is:

1. A method for operating a system with at least two automatically moving floor processing devices, comprising:
detecting with at least one of the floor processing devices environmental features in an environment,
generating an area map based on the detected environmental features, wherein the area map is divided into partial areas,
assigning the partial areas to the floor processing devices, and
processing the partial areas with the floor processing devices so that each partial area is processed by only one of the floor processing devices,
wherein a movement route of the at least one floor processing device tracked during the step of detecting as well as a movement timespan that elapsed during a movement along the movement route are detected and stored with the area map,
wherein several of the partial areas are combined into partial area groups, and wherein the partial areas are allocated to the floor processing devices, taking into consideration the stored movement route and the movement timespan in such a way that a floor processing of a first partial area group by a first one of the floor processing devices takes place at essentially the same time as a floor processing of a second partial area group by a second one of the floor processing devices is ended.

2. The method according to claim 1 , further comprising the step of determining a device-specific processing timespan that each of the floor processing devices requires to process an individual partial area, wherein the floor processing device with a smallest determined processing timespan is assigned to process said individual partial area.

3. The method according to claim 2 , wherein information about a floor type to be processed in each partial area is stored for each partial area, and further comprising the step of determining for each floor processing device which floor type-specific processing timespan the respective floor processing device would need for processing each partial area.

4. The method according to claim 2 , wherein the processing timespans required by one of the floor processing devices to process several partial areas are added together to yield an overall processing timespan, wherein the floor processing device whose overall processing timespan for previously planned floor processing activities is lowest without considering the processing timespan for the other partial areas is included in a plan for processing another partial area.

5. The method according to claim 2 , wherein the partial areas are combined into partial area groups based on a generated layout of the environment, so that room boundaries of the generated layout border partial area groups, and further comprising determining for each partial area group which processing timespan the respective floor processing device would need to process this partial area group, and wherein the partial area groups are allocated to the floor processing devices for floor processing in such a way that floor processing operations for the partial area groups are concluded at essentially the same time.

6. The method according to claim 1 , further comprising the step of assigning one of the partial areas, which is directly adjacent to a partial area or planned partial area group already assigned to one of the floor processing devices, to the one floor processing device.

7. The method according to claim 6 , wherein one out of several adjacent, not yet planned partial areas is initially assigned to one of the floor processing devices, the one partial area having a maximum distance to a partial area already planned for processing by another one of the floor processing devices or a partial area group already planned for processing by another one of the floor processing devices.

8. The method according to claim 1 , wherein a partial area for processing that has not yet been assigned to one of the floor processing devices and is not adjacent to a partial area already planned for floor processing by one of the floor processing devices or to a planned partial area group, is assigned to one of the floor processing devices whose current location has a smallest distance to the not yet assigned partial area.

9. The method according to claim 1 , wherein a floor processing activity of one of the floor processing devices in a specific partial area is only planned if the one floor processing device is suitable for a floor processing of this partial area.

10. A system with at least two floor processing devices, wherein the system is designed to implement a method according to claim 1 .
