System and method for monitoring and positioning aviation kerosene pipeline leakage

Abstract

The invention provides a system and method for monitoring and positioning aviation kerosene pipeline leakage. The system comprises a first station group, a second station group, a first station remote terminal, a second station remote terminal, a timing module and a monitoring terminal, the first station and the second station are connected through a pipeline, the first station remote terminal is connected with the first station group and used for collecting pressure, flow and temperature data of the first station, the second station remote terminal is connected with the second station group, the timing module is connected with the first station remote terminal and the second station remote terminal, and the monitoring terminal is connected with the first station remote terminal and the second station remote terminal and used for judging whether a pipeline leaks or not and judging the leakage position. Sensors used by the first station group and the second station group are MEMS optical fiber F-P pressure sensors. When a certain point on the pipeline leaks, monitoring software of a central control station gives an alarm in time for leakage occurring in an oil pipeline and determines the position of the leakage point according to collected negative pressure waves and flow signals on the theoretical basis of flow balance and a negative pressure wave method.

Description

technical field [0001] The invention relates to the field of pipeline health detection, in particular to a system and method for monitoring and locating leakage of aviation coal pipelines. Background technique [0002] Aviation kerosene (jet fuel) is the blood of the aircraft and the main component of aviation energy. The aviation kerosene pipeline is the key link from the energy transmission to the supply of aircraft flight operations, and its healthy operation will directly affect flight safety. Therefore, it is of great significance to monitor the leakage of oil pipelines. Since 2018 alone, there have been many leaks in the entire pipeline, causing large economic losses and adverse social impacts. Therefore, it is of great significance to monitor and detect the safety status of oil pipelines through technical means to ensure the health and normal operation of oil pipelines and to ensure the normal supply of combat energy. [0003] In view of the characteristics of the e...
