Description
Technical field
The present invention relates to a kind of supervisory keyboard, relate in particular to a kind of boats and ships dynamic tracking and dynamic positioning system keyboard special.
Background technology
Under general depth of water situation, mooring system is mainly adopted in the mooring of boats and ships.Along with the increase of the depth of water, the grabbing end power and will weaken of mooring system, length and the intensity of anchor chain all will increase simultaneously, and then weight increases severely, and it is complicated, difficult that therefore the operation of marine cloth chain also becomes, and cost and erected cost be improve greatly also.Along with the increase of the depth of water, factor affecting such as nature wind, wave, stream, can marine ships accurate tracking and location, to the accuracy of boats and ships deepwater work, cost, dirigibility, can be handling etc. problem play crucial effects.Because the common application of anchoring mode at the deep-sea is very limited, and therefore, just do not arise at the historic moment by means of the boats and ships dynamic tracking and the dynamic positioning system of mooring system mooring.
Boats and ships dynamic tracking and dynamic positioning system are a kind of control system of closed loop; It can constantly detect the physical location of boats and ships and the deviation of target location; Again according to the influence of disturbing forces such as the wind in the external world, wave, stream; The calculating boats and ships of sening as an envoy to return to the size of target location required drive; And each thruster on the boats and ships is carried out thrust distribute; And then make each thruster produce corresponding thrust, make boats and ships can on the sea level, keep desired a certain concrete longitude and latitude.
Boats and ships dynamic tracking and dynamic positioning system are applicable to multiple sea situation, and mobility strong, cost do not increase with the increase of the depth of water, and easy to operate.For offshore operation boats and ships such as marine drilling platform, large-scale hog barge, derrick barge, pipelaying barge, cable laying ship, maritime patrol ship, scientific investigation ship, survival craft; Mostly need dynamic tracking and dynamic positioning system, with follow the tracks of, be positioned at marine certain a bit carry out drilling well, dredge, salvaging, pipe laying, cloth cable, ocean patrol, scientific investigation, relief, etc. operation.The boats and ships that China navigates by water in the ocean at present, the basic dependence on import of dynamic tracking and dynamic positioning system.Our company has researched and developed dynamic tracking and dynamic positioning system, and this system can not compatible external dynamic tracking and the keyboard of dynamic positioning system, if adopt common PC keyboard, the technical matters of existence is: 1, adopt 5V to supply power, can not adapt to industrial control condition; 2, adopt USB or PS2 as keyboard interface, do not have reliable fixation; 3, do not have the key-press backlight lamp, and the boats and ships construction carries on construction work at night especially, unaffected for the eyesight that guarantees the driver, pilothouse will be closed illumination; 4, button is prone to take place maloperation; 5, surface of keyboard does not reach the IP22 degree of protection of " steel seagoing vessel classification rules 2006 " version regulation; 6, keyboard can not be effectively fixing; 7, the keyboard of dynamic tracking and dynamic positioning system needs specific (special) requirements such as knob signal in operation, and common PC keyboard can't reach.
Summary of the invention
