Equipment degradation state judgment system and equipment degradation state judgment method

摘要

PROBLEM TO BE SOLVED: To determine a maintenance period by grasping a facility deterioration state and abnormal sign.SOLUTION: A facility deterioration state determination system comprises: plural kinds of detection means disposed on a facility having plural kinds of appliances, and capable of detecting different physical amounts; data collection means for collecting signals output from the plural detection means; and an analyzer for determining a facility deterioration state by using a residue obtained by performing statistical processing to measurement values collected by the data processing device, as an index. The analyzer executes multiple regression analysis to the measurement values which are acquired for every appliance forming the facility, executes main component analysis to the plural kinds of measurement values acquired regardless of appliances forming the facility, and based on results of the multiple regression analysis and main component analysis, determines the deterioration state of the facility and displays a determination result on a display device.SELECTED DRAWING: Figure 5
