Abstract
The utility model relates to a boats and ships marine technology, in particular to semi -submerged formula platform propeller cooperative control system. Including PLC controller, converter, motor, mechanical transmission mechanism, multiunit screw structure, propeller, platform, the PLC controller acts on the converter as centralized control's central controller, converter and then connection motor, the motor connect mechanical transmission mechanism to act on each propeller through mechanical transmission mechanism. The characteristics of this design lie in: adopt centralized control system to application cross coupling error control algorithm, system stability is higher relatively, and the ground interference killing feature is strong, can guarantee that speed is unanimous between many propellers, has practiced thrift cost and consumption, disposes the platform in unison, and single -point fault is difficult to lateral extension.
Description
Technical field
The utility model relates to boats and ships maritime technology, particularly a kind of semi-submersible offshore platform propelling unit cooperative control system.
Background technology
Along with the automation of platform is more and more higher, more and more higher for degree of dependence that is performance-oriented, failure-free control system.And the equipment that propelling unit is platform often to be used, angle of rake control system is also indispensable corollary equipment.Multiple propeller propelling unit is made up of many pid control circuits respectively, without any contact and respectively with feedback between each loop, can regulate angle of rake speed V in each self-loop, realizes identical with its setting speed.Suppose the speed of propelling unit 1 because of ambient interference change time, any change can not be there is in the speed of residue propelling unit 2 ~ n.
Dynamic positioning technical equipment in existing boats and ships maritime technology field control and association area control system in, setting value is reached by each angle of rake speed of feedback correction although consider, but do not relate to the consistent control problem of multiple impeller speed, when running into extraneous strong disturbance, the speed of advance of platform will inevitably be caused to occur larger fluctuation, the robustness of system and less stable; Although nowadays it is also proposed the solution that multiple impeller speed is synchronous, these class methods belong to distributed system and control, waste resource and cost.
Utility model content
The utility model is intended to solve the problem, and provides a kind of semi-submersible offshore platform propelling unit cooperative control system.Adopt Centralized Control System, and use cross-coupling error control algorithm, system stability is relatively high, ground antijamming capability is strong, can ensure that between multi-thruster, speed is consistent, has saved cost and power consumption, unified configuration platform, Single Point of Faliure is difficult to extending transversely.
A kind of semi-submersible offshore platform propelling unit cooperative control system, it is characterized in that: comprise PLC, frequency converter, motor, mechanical transmission mechanism, organize propeller arrangement, propelling unit, platform more, PLC is as central controlled central control unit, connect frequency converter, frequency converter and then connection motor (3), described motor connects mechanical transmission mechanism, and connects each propelling unit by mechanical transmission mechanism, and described propelling unit connects platform.
Above-mentioned many groups propeller arrangement comprises multiple propelling unit.
Above-mentioned PLC adopts a PLC seat central control unit, and the signal feedback in each propelling unit is in PLC.
Beneficial effect: robustness, the stability of native system are relatively high, ground antijamming capability is strong, can ensure that between multi-thruster, speed is consistent, ensure that the stable motion of platform, adopt centerized fusion, saved cost and power consumption, unified configuration platform, Single Point of Faliure is difficult to extending transversely.

Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
As shown in Figure 1-2: a kind of semi-submersible offshore platform propelling unit cooperative control system, comprise PLC 1, frequency converter 2, motor 3, mechanical transmission mechanism 4, many group propeller arrangement 5, propelling unit 6, platform 7, PLC 1 is as central controlled central control unit, connect frequency converter 2, frequency converter 2 and then connection motor 3, described motor 3 connects mechanical transmission mechanism 4, and connects each propelling unit 6 by mechanical transmission mechanism 4, and described propelling unit 6 connects platform 7.
Preferred many group propeller arrangements 5 comprise multiple propelling unit 6.
Preferred PLC 1 adopts a PLC seat central control unit, and the signal feedback in each propelling unit is in PLC 1.
Specific works mode: when platform needs mobile, PLC 1 controls starter motor 3, frequency converter 2, controls frequency converter 2 change its frequency by PLC 1, and then controls motor 3, changes its rotating speed; Motor 3 driving mechanical transmission device 4 controls hand of rotation and the rotating speed of each propelling unit 6 in many group propeller arrangements 5, allows multiple propelling unit act synergistically, common determine the bow of platform to and speed, thus and then ensure that semi-submersible offshore platform stable is moved.
