Embodiment Construction

[0019] In order to make the technical solutions and advantages of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the drawings in the embodiments of the present invention:

[0020] Such as figure 1 and figure 2 A control system for a marine retractable bridge device is shown, which specifically includes a sensor perception unit, a central control unit, and a marine bridge stabilization unit.

[0021] The sensor sensing unit includes an inclination sensor, an angle encoder, a motion reference module MRU, and a tension sensor. Specifically, the inclination sensor is installed on the upper and lower stable platforms of the three-degree-of-freedom stable platform to detect the pose of the stable plane in real time. Information; the angle encoder is installed at the output end of the servo electric cylinder motor to measure the speed of the motor; the MRU is instal...

Abstract

The invention discloses a control system of an offshore telescopic gallery bridge device, which specifically comprises a sensor sensing unit, a central control unit and an offshore gallery bridge stabilizing unit, and is characterized in that a tilt angle sensor is adopted to measure a pose signal of an upper stabilizing platform, an angle encoder is adopted to measure the rotating speed of a motor, and the rotating speed is converted to obtain a driving angle; the relative pose information of the lower stabilized platform and the upper stabilized platform can be obtained, and the coupling problem of motion measurement of the ship and the stabilized platforms is solved; sea wind and sea wave grades are judged through ship pose information, and feedforward control is performed on the three-degree-of-freedom stable platform, so that the motion compensation effect of the device can be improved; in addition, according to the system, a three-degree-of-freedom stable platform is used for conducting active compensation on disturbance of complex sea conditions on the ship to conduct rolling, pitching and motion in the heaving direction, then a variable-amplitude electric cylinder and a telescopic gangway ladder are used for auxiliary motion compensation, and then the three-degree-of-freedom motion compensation effect is achieved.

Description

technical field [0001] The invention relates to the field of offshore platform control, in particular to a control system for an offshore retractable corridor bridge device. Background technique [0002] Offshore drilling platforms can exploit and store oil and gas, and offshore wind power platforms can provide a large amount of wind energy. Offshore platforms need regular personnel maintenance and personnel replacement. The main means of transportation for the staff to board the offshore platform is the ship. The situation at sea is more complex and changeable than that on land, and the hazards caused by severe weather are inevitable. In the process of transporting personnel and materials, high sea conditions generate wind, waves, and current disturbances, and collision accidents between ships and offshore platforms are prone to occur. In severe cases, the equipment may even be damaged, seriously threatening the safety of personnel. The traditional transfer methods mainly...
