基于TDLAS的管道泄漏检测载机飞行路径规划

从检测仪的检测灵敏度和检测激光对管道自主定位时保证检测管道不漏检两方面对载机的飞行路径进行规划。确定在两管段接头处载机的具体飞行方位。基于检测仪的检测灵敏度得到载机的可飞行高度与偏离管道距离的关系。结果表明:考虑实际检测时各因素的影响,建议载机飞行时偏离管线的距离应在45 m之内,飞行高度应低于110 m,且在保证飞行安全的前提下尽量降低飞行高度。

Path planning of helicopter flight with borne detector based on TDLAS for pipeline leaks detection

From the detection sensitivity of the detector and the detection laser autonomous positioning the pipeline to ensure the detection pipeline not missed, the path planning of the helicopter was given. The flight range at the joint of two pipe sections of carrier aircraft was determined. Concerning the detection sensitivity, the relationship between the flying height and the distance due to the flying deviation from the pipeline was given.The results show that the flying height is less than 110 m and the flying deviation distance from the pipeline is less than 45 m respecting the detection factors. The flying helight is reduced as far as possible under the premise of flight safety.
