Condition monitoring device, method, and storage medium

A method executed by a condition monitoring device, the method comprising:

• acquiring a time-series signal about a condition of a monitor target from a first sensor;
• acquiring operation timing information indicating start of operation of the monitor target;
• detecting a first operation segment signal from the time-series signal based on the operation timing information;
• detecting a second operation segment signal from the first operation segment signal based on a waveform feature of the first operation segment signal;
• and
• determining the condition of the monitor target based on the second operation segment signal.

A non-transitory computer-readable storage medium having stored thereon a computer program which is executable by a computer, the computer program comprising instructions capable of causing the computer to execute function of:

• acquiring a time-series signal about an condition of a monitor target from a first sensor;
• acquiring operation timing information indicating start of operation of the monitor target;
• detecting a first operation segment signal from the time-series signal based on the operation timing information;
• detecting a second operation segment signal from the first operation segment signal based on a waveform feature of the first operation segment signal;
• and
• determining the condition of the monitor target based on the second operation segment signal.
