Filed: 1991-10-02
Abstract: PURPOSE:To structure a disaster prevention system by obtaining the optical fiber type smoke and temperature sensor which can quantitatively detect smoke and temperature by winding an optical fiber for temperature distribution measurement in a coiled shape around a radiant heat source at a specific interval. CONSTITUTION:The rod-shaped radiant heat source 2 is provided droopingly at a necessary place in the laying route of the optical fiber for temperature distribution measurement which is provided along a ceiling and the optical fiber 1 for temperature distribution is wound in the coiled shape around the radiant heat source 2 at the specific interval. The coiled part of the optical fiber 1 for temperature distribution measurement is put in a cylindrical metallic case 3. In a no-fire state, no smoke is generated, so the radiant heat from the radiant heat source 2 reaches the optical fiber 1 without being cut off and a temperature rise corresponding to the capacity of the radiant heat source 2 is detected. If a fire occurs, generated smoke enters the space between the optical fiber 1 and radiant heat source 2 to cut off the radiant heat in proportion to the amount of the smoke, so a temperature drop proportional to the amount of the smoke can be detected as compared with the temperature variation in the no-fire state.
