Patent ID: 11892829
Assignee: TOSHIBA ENERGY SYSTEMS & SOLUTIONS CORPORATION
Field: Control (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A monitoring apparatus comprising:
a processing circuit,
wherein the processing circuit is configured to
acquire measurement values of sensors installed in a system,
acquire a control signal from the system,
acquire a model that generates second data including a prediction value of each of sensors belonging to a second sensor set including, as an element, a second sensor correlated with a first sensor when first data is input, the first data including a measurement value of each of sensors belonging to a first sensor set including, as an element, the first sensor of which a measurement value changes suddenly in a case where the control signal changes during a predetermined operation mode,
generate a determination signal by determining a change in the control signal,
generate the second data including a prediction value of each of the sensors belonging to the second sensor set from the first data included in the measurement value and the model, and
detect an anomaly of the system or an anomaly of at least one sensor belonging to the second sensor set based on a measurement value of each of the sensors belonging to the second sensor set, the second data, the determination signal, and a threshold, and
wherein the processing circuit is configured to restrict detection of the anomaly in a case where the determination signal indicates that there is a change in the control signal.
