Special keyboard of dynamic tracking and dynamic positioning system of ship

Abstract

The invention relates to an application for protection of a special keyboard of a dynamic tracking and dynamic positioning system of a ship. The special keyboard is connected with a system control computer; a keyboard interface and a mouse interface of the special keyboard are connected with the system control computer through D89 interfaces, and interface slipping caused by ship vibration can be effectively avoided due to D89 interface fixing devices; the DC (direct-current) 24V power supply is used to conveniently supply power; the surface adopts a PVC (polyvinyl chloride) film process to achieve the IP22 protection level; a touch button is arranged, certain pressure is needed for input, and mistaken operation can be effectively avoided in ship handling; an embedded design is adopted, the keyboard can be conveniently embedded in a ship control console, and safety can be ensured to the largest extent in a ship shaking environment; a key backlight lamp is arranged and can be adjusted to provide ten types of brightness so as to meet ship construction needs at night; and three control knobs are adopted to meet requirements for knob signals of the dynamic tracking and dynamic positioning system during the operation.

Description

technical field [0001] The invention relates to a control keyboard, in particular to a special keyboard for ship dynamic tracking and dynamic positioning systems. Background technique [0002] In the case of general water depth, the mooring of ships mainly adopts the anchoring system. As the water depth increases, the gripping force of the mooring system will weaken. At the same time, the length and strength of the anchor chain will increase, and the weight will increase sharply. Therefore, the offshore chain deployment operation will become complicated and difficult, and the cost and installation cost will also be greatly increased. With the increase of water depth, factors such as natural wind, waves, currents, etc., the precise tracking and positioning of ships at sea play a vital role in the accuracy, cost, flexibility, and maneuverability of deep-water operations. . Since the application of common mooring methods in deep sea is greatly limited, the ship dynamic tracki...

AI Technical Summary

Problems solved by technology

The company has developed a dynamic tracking and dynamic positioning system, which is not compatible with foreign dynamic tracking and dynamic positioning system keyboards. If an ordinary PC keyboard is used, the existing technical problems are: 1. Using 5V power supply, it cannot adapt to the industrial control environment; 2. USB or PS2 is used as the keyboard interface, and there is no reliable fixation; 3. There is no button backlight, and ship construction, especially at night, in order to ensure that the driver's vision will not be affected, the cab will turn off the lighting; 4. Buttons Misoperation is prone to occur; 5. The surface of the keyboard does not meet the IP22 protection level stipulated in the "Code for Classification of Sea-going Steel Ships 2006"; 6. The keyboard cannot be effectively fixed; 7. The keyboard of the dynamic tracking and dynamic positioning system needs to be There are special requirements such as knob signals, which cannot be met by ordinary PC keyboards
