1. A belt management system that is formed by a management server that manages belts that are used in a belt conveyor, a terminal that is provided in a location where the belt conveyor is installed, and a data server that is provided in a company that manufactures and sells belts, wherein
the management server is provided with:
a transceiver unit that receives in time series belt remaining thickness data that shows the thickness of the belt and that is supplied from the terminal at each one of predetermined periods;
a belt lifespan prediction unit that, by writing the belt remaining thickness data in the management database in time series, and reading from the management database the belt remaining thickness data that has been stored in time series, and dividing the difference between the predetermined periods by the usage amount of the belt at each of the predetermined periods, and determining a unit amount of change in the usage amount units, and subtracting from the most recent belt remaining thickness data a management threshold value which shows the thickness of the belt, and dividing the result of this subtraction by the unit amount of change, determines a remaining lifespan that shows the future amount of use until the belt needs to be replaced;
an expenditure database in which a total cost of ownership is written and stored, in belt conveyor units, for each different type of belt, the total cost of ownership including at least belt price, maintenance costs, and electricity cost; and
a total cost of ownership calculating unit that determines a total cost in usage amount units by dividing a sum total of the belt price, the maintenance costs, and the electricity cost that has been stored in the expenditure database by the usage amount, and associating the total cost in usage amount units with the corresponding belt of the belt conveyor and writing and storing the results in the expenditure database,
wherein a measuring device that measures the belt remaining thickness data is provided in the belt conveyer,
wherein the belt remaining thickness data is either data that has been measured and input into the terminal, or data that is measured by the measuring device and is collected from the measurement device by the terminal.
