Submarine cable detection method based on underwater robot

The invention relates to a submarine cable detection method based on an underwater robot. The method comprises the steps of detecting the temperature of a cable at a current position and the environment temperature of a cable tunnel in real time through a temperature sensor carried on the underwater robot, and photographing an image through a camera carried on the underwater robot; controlling themovement of the underwater robot based on the shot image, and obtaining the water accumulation depth of the cable tunnel; and predicting the cable temperature in the water accumulation environment based on the cable temperature, the environment temperature and the water accumulation depth of the cable tunnel. The method provides an effective detection means for personnel operation and maintenancein the cable water accumulation environment, and the method has wide application space and guiding significance for improving the stability of a power system. 本发明涉及一种基于水下机器人的海底电缆探测方法，通过搭载在水下机器人上的温度传感器实时检测当前位置处电缆温度和电缆隧道的环境温度，通
