Abstract: A control method of an integrated facility safety control system predicts short-term safety of a facility by using an artificial intelligence (AI) model embedded in an intelligent edge interrogator and predicts long-term safety of the facility on the basis of long-term sensing data received from the intelligent edge interrogator by using an AI model embedded in a server. Accordingly, a server and an intelligent edge interrogator may divisionally perform an analysis operation on the short-term safety and long-term safety of facility on the basis of data collected from an optical fiber sensor, and thus, may solve a load of data concentrating on a server, a problem of computing power, and a network problem caused by massive data transmission.
