An electronic control system for a large stern operation platform

Abstract

The invention provides a large stern working platform electric control system which belongs to the field of ship construction. The system comprises a man-machine operation interface, a system control unit, a position servo controller, an encoder and an actuator. The man-machine operation interface transmits a horizontal or vertical movement signal to the system control unit. The system control unit transmits the received signal to the position servo controller. The position servo controller sends horizontal and vertical movement signals to the actuator. The actuator carries out horizontal movement and vertical movement respectively, and transmits movement distance information to the system control unit sequentially through the encoder and the position servo controller. The system control unit carries out fine adjustment automatic correction according to feedback information. The electric control system provided by the invention is a complete closed-loop structure, can correct errors caused by component parameter variation and external disturbance, and has the advantage of high control precision. After components of combination machinery are changed, the control system does not need to be changed. The control system of a last working condition can be used. The control combination machinery has high synchronization.

Description

technical field [0001] The invention belongs to the field of shipbuilding research, and in particular relates to an electric control system for a large-scale stern operation platform, which is suitable for automatic installation and disassembly of large-scale marine propellers and rudder blades. Background technique [0002] The stern operation platform is a special tooling equipped with precise positioning and installation of rudder blades and propellers on large ships. The control method of the system belongs to the control category of the combined platform electronic control system and can be used for the control of large combined machinery. At present, shipbuilding companies mainly install and disassemble propellers and rudder blades manually, which is difficult and consumes manpower and material resources. A large-scale stern operation platform system and its control method of the present invention can effectively solve such problems. [0003] So far, there is no paten...

Problems solved by technology

[0003] So far, there is no patent related to the control system and control method of the ship's stern operating platform, but there are similar ones in other industries. The Chinese patent with the publication number CN24133222U proposes an open-loop control system for the coffee machine waterway , compared with it, the patent of the present invention has more feedback adjustments, and the control system is more accurate; the Chinese patent with the publication number CN53760825A proposes a control method for the electronic control system of a large-scale precision suspension device composite servo platform. The comparative advantage is that the synchronism of controlling the combined machinery is higher. After the components of the combined machinery are changed, the control system does not need to be changed, and the control system used in the previous working condition can continue to be used; the Chinese patent with the publication number of CN1506243A proposes a vehicle Compared with the brake control system, the patent of the present invention has the advantages of simple control method and convenient operation. The control system of CN1506243A is complicated, and it is difficult to fully realize the desired requirements

Most of the existing electronic control systems for combined mechanisms have low control precision, low control efficiency, cumbersome control methods, and high prices, making it difficult to achieve precise control of combined mechanisms and synchronous control of combined mechanisms
