Monitoring device, monitoring method, and recording medium
First Claim
1. A monitoring device comprising:
- a physical quantity acquisition section for acquiring physical quantities indicative of a state of a monitoring target device;
an abnormality determination section for determining, in accordance with whether or not the physical quantities acquired by the physical quantity acquisition section fall within a predetermined range, whether or not there is an abnormality;
an abnormal waveform data generation section for, in a case where the abnormality determination section determines that there is an abnormality, generating abnormal waveform data indicative of a change over time in the physical quantities acquired during an abnormal waveform period containing at least a period from a point in time at which the abnormality determination section determines that there is an abnormality to a point in time at which a predetermined accumulation time elapsed;
a reporting section for causing a display section to display an abnormal waveform indicated by the abnormal waveform data generated by the abnormal waveform data generation section; and
a normal waveform data management section for managing normal waveform data indicative of a change over time in the physical quantities in a normal state,the normal waveform data management section generating the normal waveform data by extracting, from the physical quantities acquired by the physical quantity acquisition section, physical quantities for which the abnormality determination section continuously determines for a predetermined time that there is no abnormality, andthe reporting section causing the abnormal waveform and a normal waveform indicated by the normal waveform data to be displayed on a single screen of the display section.

Abstract
A monitoring device includes: a physical quantity acquisition section for acquiring physical quantities indicative of a state of a device; an abnormality determination section for determining, in accordance with whether or not the acquired physical quantities fall within a predetermined range, whether or not there is an abnormality; an abnormal waveform data generation section for, in a case where the abnormality determination section determines that there is an abnormality, generating abnormal waveform data indicative of a change over time in the physical quantities acquired during an abnormal waveform period containing at least a period from a point in time at which the abnormality determination section determines that there is an abnormality to a point in time at which a predetermined accumulation time elapsed; and a reporting section for causing a display section to display an abnormal waveform indicated by the abnormal waveform data.

6. A monitoring method comprising the steps of:
-
a) acquiring physical quantities indicative of a state of a monitoring target device; b) determining, in accordance with whether or not the acquired physical quantities fall within a predetermined range, whether or not there is an abnormality; c) in a case where it is determined that there is an abnormality, generating abnormal waveform data indicative of a change over time in the physical quantities acquired during an abnormal waveform period containing at least a period from a point in time at which it is determined that there is an abnormality to a point in time at which a predetermined accumulation time elapsed; d) causing a display device to display an abnormal waveform indicated by the abnormal waveform data; and e) managing normal waveform data indicative of a change over time in the physical quantities in a normal state, the normal waveform data being generated in the step e) by extracting, from the physical quantities acquired in the step a), physical quantities for which it is continuously determined for a predetermined time in the step b) that there is no abnormality, and in the step d), the abnormal waveform and a normal waveform indicated by the normal waveform data being displayed on a single screen of the display section. - View Dependent Claims (7)
