Embodiment Construction

[0019] 1. The production steps of the four-quadrant horizontal attitude sensor:

[0020] (1) Light-emitting layer The light-emitting element is selected from the commercially available square high-brightness white LED array, and its external dimensions match the combined size of four square photoelectric conversion devices.

[0021] (2) For the light-transmitting layer, select two square colorless and transparent sheets that match the combined area of ​​four square photoelectric conversion devices and have a thickness of about 0.5-1.0 mm. Use a thickness of 1-2 mm, a width of 2-3 mm, and a Flat strips of the same material with equal side lengths are bonded between two colorless transparent sheets along the three sides of the sheet to form a thin dish with one side open ( image 3a); Pour colored liquid (water) into the thin dish, leave a little air, and then use a flat strip of the same size as the above to seal the opening, and the residual air sealed in the interlayer will f...

Abstract

A control system for automatically maintaining the horizontal posture of part of a deck of a ship or the work plane of instrument equipment is composed of a four-quadrant horizontal posture sensor, a control device, a servo mechanism and a deck frame. The servo mechanism is formed by hydraulic cylinders or air cylinders and electronic control pressure release valves, and the extending ends of piston rods of the four servo cylinders arranged vertically are connected with the four vertex angles of the frame. The coordinate original point of the four-quadrant horizontal posture sensor coincides with the geometrical center of the deck or a platform, output signals of the four-quadrant horizontal posture sensor represent inclination directions and degrees, and the servo mechanism is controlled through proportional-integral controllers to maintain the horizontal posture of the frame.

Description

[0001] Field [0002] The invention belongs to the technical field of active sway control, in particular to a control system for automatically maintaining the horizontal posture of a local deck of a ship. Background technique [0003] Under the action of wind and waves, the ship's pitch and roll attitude changes, and the deck or platform also tilts longitudinally and laterally with the hull, causing physical discomfort to personnel and affecting the working status of instruments and equipment. In the existing ship control technology that overcomes the above drawbacks, it is divided into two categories: passive control and active control. Passive anti-sway measures are mostly reflected in the design of the hull structure, or equipped with a specially designed mechanical self-balancing device; active anti-sway systems need to use auxiliary energy and power to reduce various fluctuations on the deck or platform due to changes in the attitude of the hull. It is mostly used in eng...
