Abstract:
1. An object subject system including a plurality of objects subject to be processed, wherein: each of the objects subject to be processed is provided with an object body to be processed and a device including a processing unit, a storage unit, and a communication unit; said storage unit for each of said objects subject to be processed is arranged to store an identifier of said object with which the storage unit is provided, a product specification including a service condition of said object, and a usage situation of said object; said processing unit for each of said objects subject to be processed renews said usage situation of said object in said storage unit provided therewith on the basis of the identifier of said object and a usage situation of said object received from other objects subject to be processed, determines whether or not said renewed usage situation is within a predetermined service condition of said product specification stored in said storage unit, and outputs a request for predetermined processing for another object subject to be processed when said processing unit judges that the predetermined processing is required for said object, wherein: said other objects subject to be processed include an accelerometer and a decoder for recording a number of rotations of said object; said product specification stored in said storage unit includes a relation between usage conditions of said object including either acceleration or deceleration and an endurance distance of said object; said usage situation stored in said storage unit includes a traveling distance of said object converted on the basis of the usage conditions of said object; said usage situation received from said other objects subject to be processed includes a traveling distance of said object received from said decoder and usage conditions of said object received from said accelerometer; and said processing unit renews a using distance of said object stored in said storage unit on the basis of a traveling distance of said object received from said decoder and a usage condition of said object received from said accelerometer, determines whether or not the renewed using distance of said object is within a range of an endurance distance converted on the basis of a relation between the usage condition of said object stored in said storage unit and the endurance distance of said object, and outputs a warning for conversion of said object to said other objects subject to be processed when the using distance of said object is not within the range of said endurance distance.
