  • Monitoring apparatus, method, and program
    Patent number: 11892829
    Abstract: According to one embodiment, a monitoring apparatus includes a processing circuit. The processing circuit is configured to generate second data including a prediction value of a second sensor correlated with a first sensor from first data including a measurement value of the first sensor of which a measurement value changes suddenly in a case where the control signal changes, detect an anomaly of the system or an anomaly of at least one sensor, and make it difficult to detect the anomaly in a case where the determination signal indicates that there is a change in the control signal.

  • Signal transmission and reception system, installation method of the system, and plant applied with the system
    Patent number: 9054776
    Abstract: A signal transmission and reception system includes a transmitter adapted to transmit a signal by radio, and a receiver adapted to wirelessly receive the signal from the transmitter and transmit the signal to a monitoring and control device of a plant through a transmission cable connecting the receiver to the monitoring and control device, wherein the transmitter and the receiver are provided in the plant, and wherein the receiver is attached to a cable tray used to lay a cable other than the transmission cable.
