PROBLEM TO BE SOLVED: To prevent wrong diagnosis occurring by a use state of a movable body, environmental change or maintenance work.SOLUTION: A failure sign diagnostic system comprises: an equipment state prediction device configured to estimate an equipment deterioration state on the basis of history of an operation signal of equipment; an equipment state calculation device configured to calculate a deterioration state using the latest input operation signal of the equipment; and an inspection timing estimation device configured to estimate inspection timing on the basis of the deterioration state (prediction value) estimated by the equipment state prediction device and the deterioration state (current value) calculated by the equipment state calculation device. The inspection timing estimation device selects either inspection timing determination with the prediction value and inspection timing determination with the current value, on the basis of the difference (prediction error) between the predication value and the current value.SELECTED DRAWING: Figure 1 |
