三峡水库变动回水区卵石输移音频信号分析系统开发
|
摘要
三峡变动回水区在三峡水库175m蓄水以来以消落期卵石浅滩碍航问题为主,但测量卵石输移强度难度较大。结合自主研发的水下卵石音频采集设备,基于Matlab平台,设计卵砾石音频分析计数可视化软件。该软件具有读取音频文件、提取音频文件信息、音频文件预处理、音频特征参数分析、卵石碰撞识别计数、估算卵石输移强度等功能。为解决三峡变动回水区卵石碍航问题提供一定参考。
Since the Three Gorges Reservoir backwater area has been 175 m water storage in the Three Gorges Reservoir, the problem of obstruction of the pebble shoal is mainly due to the erosion, but it is difficult to measure the pebble transport intensity. Combined with the self-developed underwater pebble audio acquisition equipment, based on Matlab platform, design the visual analysis software for the gravel audio analysis and counting. The software has the functions of reading audio files, extracting audio file information, audio file preprocessing, audio feature parameter analysis, pebble collision recognition counting, and estimating pebble transmission intensity. To provide a reference for solving the problem of pebbles in the backwater area of the Three Gorges.
