| 摘 要： | 为了防止升船机船厢搁浅事故的发生,开发了一套基于超声波散射分析的富余水深检测系统.该系统基于水下超声波传输时遇到障碍物发生散射的特性,通过FPGA控制超声波发射阵列在升船机船厢内构建多个横向的超声波相对路径,并通过接收阵列采集声压数据,将数据发送给富裕水深检测软件进行数据的线性回归分析及富余水深的计算.该系统已应用于向家坝升船机船厢内,具有稳定性强、安装方便、实时性高等优点.

| Abstract: | In order to prevent the ship cabin grounding accident of ship lift, a set of redundant water depth detection system based on ultrasonic scattering analysis is developed. Based on the scattering characteristics of obstacles encountered in underwater ultrasonic transmission, the system uses FPGA to control the ultrasonic transmitting array to build multiple transverse ultrasonic relative paths in the cabin of the ship lift, and collects the sound pressure data through the receiving array, and sends the data to the software for data analysis and calculation of the affluent distance. The system has been used in the chamber of Xiangjiaba ship lift. It has the advantages of strong stability, convenient installation and high real-time performance. |
