1. A system for collecting, with reduced collected data amount, operation information of a fluid control device, the system comprising:
a detected value acquisition means acquiring detected values from the fluid control device, as acquired detected values, wherein the detected values are, for a predetermined time zone during the acquiring, detected values of a state change or a device operation that is able to detect opening and closing operations of the fluid control device;
a calculation processing means calculating, based on two or more of the acquired detected values acquired during the predetermined time zone, a rate of change of the acquired detected values separated by a predetermined time; and
an operation information registration means registering, to an operation information storage means, the calculated rate of change of the acquired detected values separated by the predetermined time, as a collected operation information of the fluid control device,
wherein a data amount of the collected operation information of the fluid control device is a reduced data amount in comparison to a data amount of the acquired detected values.
