transmits the device location information, shape information, maintenance information, projection location information, and abnormality information to the autonomous mobile body when receiving the abnormality information, and

the autonomous mobile body having a projection unit configured to project a moving image or still image:

travels to a location of the abnormal device, based on the abnormality information and the device location information, and

projects, by the projection unit, the maintenance information at a projection location of the abnormal device based on the projection location information.

2. The maintenance support system according to claim 1 , wherein

at least one of the autonomous mobile bodies includes at least one of a sound-generating unit configured to generate sound and a light-emitting unit configured to emit light at least after traveling to the location of the abnormal device.

3. The maintenance support system according to claim 1 , wherein

at least one of the autonomous mobile bodies is configured to convey a maintenance tool.

4. The maintenance support system according to claim 1 , wherein

at least one of the autonomous mobile bodies includes a photographing unit configured to photograph the devices, and

the terminal is configured to receive image data corresponding to the abnormal device that is photographed by the photographing unit, and associates the image data that is received with the abnormality information and stores the image data in a storage unit.

5. The maintenance support system according to claim 1 , wherein

at least one of the autonomous mobile bodies is a flying object.

6. The maintenance support system according to claim 1 , wherein

at least one of the autonomous mobile bodies includes a movement mechanism and an energy accumulation unit configured to accumulate energy to be applied to the movement mechanism, and

when an energy amount in the energy accumulation unit is less than a predetermined amount, the terminal transmits the instruction signal to another autonomous mobile body.

7. The maintenance support system according to claim 6 , wherein
