  • Publication number: 20240094720
    Abstract: In a facility state monitoring system, a sensor node includes a sensor that outputs, as sensor data, data indicating the state of a facility as a monitoring target, a communication unit, and a power supply unit that supplies power to the sensor and the communication unit. The sensor node is commonly used by multiple monitoring targets. A receiver receives the sensor data transmitted from the communication unit. A state detection unit receives the sensor data received by the receiver, and learns, as learning data, normal states of the monitoring targets based on normal sensor data corresponding to normal operations of the monitoring targets. In response to the receiver receiving the sensor data transmitted from the sensor node after learning, the state detection unit compares states of the monitoring targets indicated by the sensor data with the learning data to detect an abnormality occurrence or symptom in the monitoring targets.
