摘要： Provided are an apparatus and method for adjusting an optical axis. In the apparatus, an iris diaphragm and a quadrant photodiode (QPD) are used to align optical axes of an optical system of the apparatus so that optical transmission efficiency between an optical transmitter and an optical receiver can be increased. Since a hole of the iris diaphragm can be adjusted to be small, a beam larger than a light-receiving area of the QPD can be included in the light-receiving area, and optical axis alignment is facilitated accordingly. When the QPD and the iris diaphragm are applied to the apparatus, it is possible to simultaneously perform data transmission, tracking, and optical axis alignment. An optical fiber end surface and optical axes of lenses arranged in parallel are aligned in the apparatus so that alignment between two terminals can be easy and reception efficiency can be increased.

摘要： 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.
