The invention discloses a method and
system for field application and calibration of a reflection
fiber optic displacement sensor. The method includes the steps that when a
target surface is monitored to be in the range of a
laser displacement sensor and the
fiber optic displacement sensor, the preset
moving speed, the preset moving distance and the preset moving direction of the
target surface are set; a motor controls the
target surface to move according to the preset
moving speed, the preset moving distance and the preset moving direction, and the measurement value collected by the
laser displacement sensor is read in real time in the moving process; the actual
moving speed of the target surface is calculated according to the measurement values, and when the actual moving speed is judged to be consistent with the set moving speed, the measurement value collected by the
laser displacement sensor is recorded, and the
voltage value measured by the
fiber optic displacement sensor is read; accurate time hack is conducted on the measurement value and the
voltage value, then storage is conducted, and fitting is conducted according to the measurement value and the
voltage value to generate a
calibration curve. The method and
system for field application and calibration of the reflection
fiber optic displacement sensor solve the problem that a fast and high-precision field suitable for different reflection conditions for calibration cannot be built at present.
