| 摘 要： | 基于光纤水声传感器,提出了一种水声信号能量阈值与强线谱时频特征相结合进行内河航道航运流量监测的方法,解决了内河航运流量较大时,特别是多艘船只同时通过时的船只计数难题.时长45min的现场声压数据的处理结果验证了该方法的有效性.

| Abstract: | Based on a set of optic fiber sensors, an algorithm was proposed to count ships in inland waterways by combining the threshold of sound energy and the time-frequency characteristics of strong line spectrums, which solved the counting problem emerged when a number of ships went through the monitored water area in parallel. The processing results of a piece of 45 minutes long sound pressure data proved the effectiveness of this algorithm. |
