  Further, the facility-related person 5 can check the operation time information of the lights 6 that are aggregated every month together with the monthly weather information 329. As a result, for example, in a month with a lot of rain, the amount of sunshine decreases and the operation time of the light 6 increases, so that it is possible to obtain a guideline for the maintenance work contents associated with the weather information 329.

  In addition, at the time when there is no abnormality in the light 6, it is possible to confirm the remaining time (second predicted time data T2P) that is predicted to be usable until an abnormality occurs in the future. As a result, preventive maintenance work can be performed before a failure occurs in the equipment, and further stable operation of each facility becomes possible.
