摘要
A system and a method for calibrating a distributed optical fiber for health perception of a water-adjacent building, comprising a heat insulation barrel, and a plurality of calibration modules located in the heat insulation barrel around the axis thereof. Each calibration module comprises a through shaft (313), a first electronic thermometer (341) and a second electronic thermometer (345). The through shaft (313) is wound with an optical cable to be calibrated (348). The optical cable to be calibrated (348) is connected to an optical fiber temperature demodulator outside the heat insulation barrel. The first electronic thermometer (341) and the second electronic thermometer (345) are connected to a first temperature control meter (306) and a second temperature control meter (308) outside the heat insulation barrel, respectively. A temperature source heat wire (353) for heating water in the heat insulation barrel is disposed in a barrel wall of the heat insulation barrel. The temperature source heat wire (353) is connected to a power temperature control meter (310) outside the heat insulation barrel. The first temperature control meter (306) is connected to temperature drop and rise apparatuses by means of a first temperature control meter wire. The system for calibrating a distributed optical fiber for health perception of a water-adjacent building can realize high-precision calibration for a long-distance optical cable once by flexibly controlling temperature change in a heat insulation barrel via the temperature drop and rise apparatuses. Also disclosed is a method for calibrating a distributed optical fiber for health perception of a water-adjacent building.
