HYBRID FIRE MONITORING SYSTEM USING FIBER OPTIC TEMPERATURE SENSORS AND LINEAR FIXED-TEMPERATURE DETECTORS

摘要

The present invention relates to a hybrid fire monitoring system using an optical fiber temperature sensor and a constant temperature-type line detector, and more particularly to a hybrid fire monitoring system using an optical fiber temperature sensor and a constant temperature-type line detector, which enables an optical fiber temperature sensor configured to readily detect a relatively big fire through measurement of temperature distribution across a large area and a constant temperature-type line detector configured to readily detect whether a temperature at a specific location exceeds a reference temperature to complement each other, thereby rapidly detecting occurrence of a fire and dealing with the fire. For this purpose, according to the present invention, the hybrid fire monitoring system using an optical fiber temperature sensor and a constant temperature-type line detector comprises: a measurement target; optical fiber which is installed on the measurement target; a light source unit which emits light to the optical fiber; a temperature measurement unit which is disposed at a starting end of the optical fiber; and a control unit. In this case, the hybrid fire monitoring system may further comprise a constant temperature-type line detector disposed on an overall or partial portion of the measurement target on which the optical fiber is installed, and a line fire detection unit disposed in the constant temperature-type line detector and configured to measure a current or resistance value of the constant temperature-type line detector and detect occurrence of a fire and a location of the fire. Furthermore, the line fire detection unit may be electrically connected to the control unit.
