Health diagnosis device, health diagnosis method, and health diagnosis program

摘要

It is an object of the present invention to provide a condition diagnosis apparatus, a state diagnosis method, and a state diagnosis program capable of predicting failures by monitoring the state of a diagnosis target, and predicting age deterioration. The condition diagnosis device 1 sequentially measures and collects measurement data in a plurality of monitoring items for a device to be diagnosed, and the measurement data collection unit 12 that accumulates and stores each monitoring item calculated from the accumulated measurement data. A calculation unit that calculates the allowable range of each monitoring item based on the standard value and the standard deviation, and updates the standard value and the allowable range from time to time using the measured data accumulated in the first past predetermined period from the present time. (14) and an evaluation unit (15) for evaluating the state of the device by using the allowable range calculated by the calculation unit (14), and the calculation unit (14) is based on the standard deviation of the standard value for each monitoring item. From the measurement data accumulated in the second past predetermined period of a period longer than the first past predetermined period, a predetermined weight is set and an allowable range of each monitoring item is calculated.
