PROBLEM TO BE SOLVED: To efficiently reuse components of an automatic vending machine. SOLUTION: This system has temperature sensors 12a, 22a, 32a detecting temperature of fan motors 12, 21, 31 provided inside an automatic vending machine body 1; a storage part 53 storing temperature data obtained by the temperature sensors 12a, 22a, 32a as history data 53a; and a remaining service life calculation part 52a finding a temperature time product of the fan motor 12, 21, 31 up to the present on the basis of a history of the temperature data stored in the storage part 53, subtracting the temperature time product up to the present from a reference temperature time product showing the preset whole service life of the fan motor 12, 21, 31, dividing the subtracted remaining temperature time product by a temperature shown by the temperature data in temperature environment of target equipment to be used thereafter, and calculating the time, that is the division result, as a remaining service life. |
