The fin stabilizer control device that has " GPS "

Technical field:

The utility model relates to a kind of equipment that reduces the ship motion of rolling, particularly a kind of equipment that uses hydrofoil to act on the motion of the ship of water surface minimizing on every side.

Background technology:

Ship is in ocean navigation, under wind wave action, produce rolling, the lateral oscillation of boats and ships can reduce its navigability, the injured vessel body structure, influence the normal operation of equipment, instrument, goods displacement or bump are damaged, passenger and crewman are swooned, serious rolling may cause danger, for combat vessel then may influence or even the forfeiture operational efficiency, in order to reduce waving of boats and ships, adopt all ways the dealer of this technical field, as bilge keel, antirolling tank, subtract and shake gyro, subtract and shake weight and stabilizer or the like and subtract the equipment of shaking; Increase day by day along with development of technology and high speed ship quantity, also since the stabilizing efficiency of stabilizer and the speed of a ship or plane of boats and ships be directly proportional, stabilizer has become higher speed of a ship or plane naval vessel and has reduced to wave one of visual plant that improves the naval vessel performance, existing fin stabilizer control device as shown in Figure 3, when boats and ships produced rolling under sail, the rolling signal of being measured boats and ships by gyroscope (included angular displacement, cireular frequency

And angular acceleration ), (speed of a ship or plane v) to measure the route speed signal of boats and ships by log again, above-mentioned signal input master control system, after conversion is amplified, order about fin and rotate a cooresponding angle, fin is at the flow action of the corresponding speed of a ship or plane, produce a balancing torque opposite with the ship rolling direction, this balancing torque makes waving of ship will be subjected to very big damping, thereby amplitude of roll is reduced greatly, obviously in the fin stabilizing system working process, log input speed of a ship or plane signal is the effectively necessary condition of work of system, thereby log is an equipment element indispensable in the fin stabilizer control device, usually be to import the contact in master control system with S7-200PLC, acceptance after identification is resolved, is carried out " speed of a ship or plane adjusting " to the fin angle of stabilizer from 200 pulses/the passive or active contact signal in the sea of log; But, existing log is owing to structure more complicated, technological requirement essence, components and parts cost an arm and a leg, and its restricted application can't form large-scale production, thereby its cost of manufacture is high, cause economical burden to the user, from the present technique field,, reduce equipment cost along with the increase of stabilizer demand, as replace existing log with low-cost equipment, be measure with important economic implications; In today that up-to-date technology develops rapidly, global positioning system (GPS) is in departments such as Aeronautics and Astronautics and automobiles, a large amount of application of having succeedd, it not only has the potential key element of technology that exploitation replaces log, and price is also cheaper, thereby technical foundation is provided for the application of GPS on fin stabilizer control device.

The utility model content:

Technical problem to be solved in the utility model is, provide a kind of and have the fin stabilizer control device of " GPS ", it can keep fin stabilizer control device to have the standard that meets technical requirements, can replace expensive log with the GPS of cheapness again and has great economic implications.

The technical scheme in the invention for solving the above technical problem is:

Having the mouth of master control system of fin stabilizer control device of " GPS " and the input end of hydraulic efficiency servo is connected, the actuating unit of hydraulic efficiency servo is connected with fin, the angular displacement signal mouth of fin is connected through the input end of positioner and master control system, the 1st signal source angular velocity gyro mouth of device and the input end of master control system are connected, angular velocity gyro is to the rolling motion signal of master control system input boats and ships, be characterized in: another input end of master control system is connected with a global positioning system (GPS), GPS is to the speed of a ship or plane signal of master control system input boats and ships, the 2nd signal source for device, the the 1st and the 2nd signal source of device is respectively with ship rolling motion signal and speed of a ship or plane signal input master control system and hydraulic efficiency servo, after the treated amplification, actuating unit by hydraulic efficiency servo rotates fin to corresponding angle, set up the balancing torque opposite with the ship rolling direction, the angular displacement signal of fin is imported master control system through positioner, realizes subtracting shaking function.

The utility model replaces the required speed of a ship or plane signal of existing log generator with GPS, obtain to have good stabilizing efficiency through test, and the price of GPS only is 1/10 to 1/20 of the log price now selected for use, undoubtedly, to growing stabilizer demand, not only can obtain bigger economic interests to the user, and to promoting that promoting the use of of stabilizer also has splendid effect.
