The invention provides a tsunami monitoring and early warning method and an integrated underwater unit thereof. The method comprises the steps: arranging a high-precision pressure sensor, an underwater acoustic communication module and a power supply system on a bearing shaft; enabling the high-precision pressure sensor to collect seabed pressure data, analyze the seabed pressure data and transmitthe seabed pressure data back to the tsunami buoy through the communication module; when the analyzed pressure value exceeds a set threshold value, enabling the high-precision pressure sensor to directly transmit the seabed pressure data back to the tsunami buoy through the communication module, and judging whether pressure change is caused by tsunami or not through a tsunami analysis algorithm of the tsunami buoy; and enabling the tsunami buoy to transmit the data back to the shore-based data receiving terminal through the satellite module. According to the tsunami monitoring and early warning method and the integrated underwater unit thereof provided by the invention, the change of the underwater pressure is monitored with high precision in real time through the high-precision pressuresensor, so that misinformation and wrong faults are reduced, and the monitoring efficiency is improved.

    本发明提供了一种海啸监测预警方法及其一体式水下单元,将高精度压力传感器、水声通讯模块和电源系统设置在承力轴上;高精度压力传感器采集海底压力数据,解析后,通过通讯模块回传到海啸浮标;当解析的压力值超过既定阈值时,高精度压力传感器使海底压力数据直接由通讯模块回传到海啸浮标,由海啸浮标的海啸解析算法来判断压力变化是否由海啸引起;海啸浮标通过卫星模块将数据传送回岸基数据接收终端。本发明提供的海啸监测预警方法及其一体式水下单元,通过高精度压力传感器,对水底压力的变化进行了实时高精度地监测,减少了误报及错误的故障,提高了监测效率。
