摘要
文中提出了一种基于 ARM+FPGA 架构的可检测宽航道的通航船舶吃水检测系统。该系统利用水下超声波传递同步控制信息解决宽河道的吃水检测难题,并根据通航船舶对水下超声波传输路径的遮挡发生的衍射效应,同时结合实时水位数据,送入上位机分析得出通航船舶的实时吃水量。现场试验表明,该系统具有检测范围宽、安装方便、实时性高的优点,其测量精度 2.8 cm。
This paper put forward a draft detection system based on ARM&FPGA architecture which can test the draught of wide navigable channel.This system uses the ultrasonic to deliver control signal and solve the problem of the wide channel water detection.According to the diffraction effect of the navigation ship to the underwater ultrasonic transmission path,combine with the real time data of water level,then the real time water consumption of the navigable ship is analyzed.Field experiments show that the system has advantages of wide detection range,convenient installation and high real time performance,and its measurement is 2.8 cm.
