Operating state management device, operating state management system, and operating state management method

An operating state management system comprising:

• a plurality of sensors that are provided in each of a plurality of operating state management target devices, the plurality of sensors detecting states of individual components;
• an operating state management device including:
• a first memory configured to store feature patterns of detection states of the sensors in association with operating states;
• a processor configured to compare patterns corresponding to actual detection states of the plurality of sensors with the feature patterns stored in the first memory, and determine operating states;
• and
• a second memory configured to store the determined operating states in time series, the processor being configured to perform an analysis of a loss cause in a predetermined time zone based on the operating states stored in time series;
• and
• a display device configured to present a result of the analysis performed by the processor.

An operating state management method executed by an operating state management device configured to perform operating state management based on detection states of a plurality of sensors, the plurality of sensors being provided in each of a plurality of operating state management target devices and detecting states of individual components,

• the operating state management method comprising:
• storing in advance feature patterns of detection states of the sensors in association with operating states;
• comparing patterns corresponding to actual detection states of the plurality of sensors with the feature patterns and determining operating states;
• storing the determined operating states in time series;
• performing an analysis of a loss cause in a predetermined time zone based on the operating states stored in time series;
• and
• presenting a result of the analysis.
