Abstract

A spatial information delivery system according to an embodiment of the present invention includes a partial spatial information generation device, and a plurality of partial spatial information transmission devices existing within a facility. The partial spatial information generation device generates partial spatial information which is part of spatial information relating to the facility and which is specific to each of the partial spatial information transmission devices, for each of the partial spatial information transmission devices based on locations of the partial spatial information transmission devices. Each of the partial spatial information transmission devices transmits the partial spatial information corresponding to the own partial spatial information transmission device.

First claim

The invention claimed is:

1. A spatial information delivery system comprising:
a partial spatial information generation device; and
a plurality of partial spatial information transmission devices existing within a facility,
wherein the partial spatial information generation device extracts partial spatial information from spatial information relating to the facility for each of the partial spatial information transmission devices based on locations of the partial spatial information transmission devices, the partial spatial information being part of the spatial information and specific to each of the partial spatial information transmission devices, and
each partial spatial information transmission device transmits the partial spatial information corresponding to the specific partial spatial information transmission device.

2. The spatial information delivery system according to claim 1 ,
wherein the partial spatial information generation device includes a path between a partial spatial information transmission device corresponding to the partial spatial information and other partial spatial information transmission devices existing within a spatial object included in the partial spatial information, in the partial spatial information.

3. The spatial information delivery system according to claim 1 ,
wherein each partial spatial information transmission device transmits the partial spatial information or information for receiving the partial spatial information using a push-type communication scheme.

4. The spatial information delivery system according to claim 1 ,
wherein the partial spatial information generation device includes a spatial object for which it is judged that a logical distance to the partial spatial information transmission device associated with the partial spatial information to be generated is equal to or less than a threshold among spatial objects included in the spatial information, in the partial spatial information,
wherein the logical distance is the number of other spatial objects existing between the partial spatial information transmission device and the spatial object.

5. The spatial information delivery system according to claim 1 ,
wherein the partial spatial information generation device eliminates a spatial object for which it is judged that a physical distance from a reference point is equal to or greater than a threshold from the partial spatial information.

6. The spatial information delivery system according to claim 1 ,
wherein the partial spatial information generation device eliminates information relating to an object which is judged as unnecessary based on maintenance information relating to objects existing in the facility from the partial spatial information.

7. The spatial information delivery system according to claim 1 ,
wherein the spatial information includes attributes of objects existing in the facility, and
the partial spatial information generation device eliminates information relating to an object judged as unnecessary based on the attributes from the partial spatial information.

8. The spatial information delivery system according to claim 1 ,
wherein the partial spatial information transmission device confirms operation states of other partial spatial information transmission devices, and eliminates a path relating to a partial spatial information transmission device which does not operate among the other partial spatial information transmission devices from the partial spatial information.

9. The spatial information delivery system according to claim 1 ,
wherein the partial spatial information transmission device is connected to a battery which supplies power in the case where a power supply system within the facility is stopped.

10. The spatial information delivery system according to claim 2 , further comprising:
a partial spatial information processing device configured to determine a path for moving from a first partial spatial information transmission device which is one of the plurality of partial spatial information transmission devices to a second partial spatial information transmission device which is one of the partial spatial information transmission devices based on the path included in the partial spatial information.

11. The spatial information delivery system according to claim 10 , further comprising:
a movement device configured to move along a path determined by the partial spatial information processing device,
wherein the movement device comprises:
a sensor;
a recognizer configured to recognize a target object from objects recognized by the sensor based on identification information for identifying objects included in the partial spatial information; and
a location/orientation corrector configured to correct a current location and orientation of the movement device based on orientation and a distance to the target object and a location of the target object.

12. A spatial information delivery method for delivering spatial information by a plurality of partial spatial information transmission devices existing within a facility, the spatial information delivery method comprising:
extracting partial spatial information from spatial information relating to the facility for each of the partial spatial information transmission devices based on locations of the partial spatial information transmission devices, the partial spatial information being part of the spatial information and specific to each of the partial spatial information transmission devices; and
transmitting by the partial spatial information transmission device, the partial spatial information corresponding to the specific partial spatial information transmission device.

13. A non-transitory computer readable medium having a computer program for delivering spatial information by a plurality of partial spatial information transmission devices existing within a facility, the computer program comprising:
extracting partial spatial information from spatial information relating to the facility for each of the partial spatial information transmission devices based on locations of the partial spatial information transmission devices, the partial spatial information being part of the spatial information and specific to each of the partial spatial information transmission devices; and
transmitting by the partial spatial information transmission device, the partial spatial information corresponding to the specific partial spatial information transmission device.
