摘　　要：针对可视化的堤坝渗漏点检测方法精度低、成本高的缺点,设计了一种堤坝渗漏探测系统。该系统采用ARM作为控制核心,由水听器完成水声信号采集,由ADS1256芯片对水声信号进行A/D转换,由LM393芯片完成入水检测,由MS5837芯片检测入水深度,经RS485总线完成数据高速传输,在上位机上使用LabView编写软件对数据进行处理和显示。实验结果表明,该系统在水面以下堤坝深度600 m范围内可以精确检测堤坝渗漏位置,而且图像显示实时性强,能够广泛满足堤坝渗漏探测的需求。In order to overcome the shortcomings of low accuracy and high cost of visualized dam leakage detection method,a dam leakage detection system was designed.The system used ARM as the control core,the hydrophone completed the acquisition of underwater acoustic signals,the ADS1256 performed A/D conversion of underwater acoustic signals,the LM393 completed the water entry detection,the MS5837 detected the depth of water entry,the bus RS485 completed the high-speed data transmission,and the LabView software was used to process and display the data on the host computer.Experiments showed that the system can detect the leakage position of dam in the depth within 600 meters below the water surface and has real-time image display,which can be widely used to meet the needs of dam leakage detection.
