Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] In the anchoring positioning system, the positioning winch is the key equipment to achieve anchoring positioning. The positioning winch in this system includes a tension winch and a storage winch, wherein the tension winch and the storage winch are connected by a wire rope, and the tension winch and the storage winch The steel wire rope may undergo flexible deformation. As a power winch for retracting and unwinding cables, the tension winch is a double-drum friction winch; the capacity of the tension winch to accommodate the wire rope is limited, and it is necessary to use the storage winch to help the tension winch store the wire rope, so the drum of the tension winch and the drum of the storage winch must be kept Synchronous action, so as to realize the orderly winding of the wire rope. At the same time, if there is no certa...

Abstract

The invention provides a master-slave control system for automatically tensioning a winch mooring rope of an anchor moored positioning system. The master-slave control system comprises a man-machine interface, a control unit, a transmission unit and an execution unit. The transmission unit comprises an ABB master frequency converter and an ABB slave frequency converter. The execution unit comprises a tension winch motor, a rope storage winch motor, a tension winch and a rope storage winch. The control unit is in communication connection with the ABB master frequency converter and the ABB slave frequency converter. The ABB master frequency converter is connected with the tension winch motor, the ABB slave frequency converter is connected with the rope storage winch motor, and the ABB master frequency converter is in communication connection with the ABB slave frequency converter. Software mathematic models of alternating current asynchronous motors are arranged in the ABB master frequency converter and the ABB slave frequency converter and capable of controlling the rotating speeds of the tension winch motor and the rope storage winch motor respectively, speed synchronization between the tension winch and the rope storage winch is kept, and the automatic tensioning function of the tension winch and the rope storage winch is achieved.

Description

technical field [0001] The invention relates to a master-slave control system, more specifically to a master-slave control system for realizing the automatic tensioning of the winch cable of the mooring positioning system, and belongs to the technical field of deep-water mooring positioning systems. Background technique [0002] The development of offshore oil and gas resources in my country is still in the early stage. With the acceleration of the development of deep sea oil and gas in the world, it will definitely promote the development of deep water oil and gas resources in my country. Therefore, the research on deep water semi-submersible offshore platforms is of great significance. [0003] The mooring positioning system is one of the indispensable and important control systems of the semi-submersible platform, and the positioning winch is the key equipment to realize the mooring positioning. The positioning winches in this system include tension winches and rope storag...
