Intelligent control method and system for underwater double-platform butt-joint lifting operation

The invention discloses an intelligent control method and system for underwater double-platform butt-joint lifting operation, and relates to the field of intelligent control over underwater double-platform butt-joint lifting operation, the system comprises underwater double platforms and an upper computer controlling the underwater double platforms, the underwater double platforms comprise a mother boat and a lifting robot used for butt-joint lifting of a target object, and the mother boat is connected with the lifting robot. The mother boat carries a winch and a hoisting robot. When the target object is docked, the mother boat is located at a preset hovering position, the hoisting robot is laid, and in the process of laying the hoisting robot, the position state of the hoisting robot is adjusted based on the horizontal relative position between the hoisting robot and the target object till the hoisting robot is aligned with the target object and docked with the target object. And after the lifting robot is i
