titleOfInvention | Multi-parameter multi-mode high-precision pipeline leakage monitoring and positioning system |
abstract | The invention discloses a multi-parameter multi-mode high-precision pipeline leakage monitoring and positioning system, which comprises a weak reflection point array optical fiber, a sensing optical fiber, a demodulation module and a comprehensive analysis module; the information obtained by sensing of the weak reflection point array optical fiber and the sensing optical fiber is demodulated by the demodulation module and then is connected with the comprehensive analysis module; the weak reflection point array optical fiber is laid on the inner wall or the outer wall of the measured pipeline; the sensing optical fibers are laid and packaged on the outer wall of the measured pipeline through the water-swellable material; the demodulation module comprises a temperature demodulation submodule, a humidity demodulation submodule, a vibration demodulation submodule, a sound wave positioning submodule and a signal demodulation optical switch; the weak reflection point array optical fiber is connected with the acoustic positioning sub-module; the sensing optical fiber is connected with the signal demodulation optical switch, and the signal demodulation optical switch is used for time-sharing switching of the temperature demodulation submodule, the humidity demodulation submodule and the vibration demodulation submodule. The invention can realize the real-time monitoring of a plurality of parameters of the pipeline in a large range, and has high positioning precision and strong anti-interference performance. |
