All ratation towboat rudder paddle control system

Abstract

The all-rotation towboat rudder paddle control system includes central processing unit, steering handle, handle rotating signaling potentiometer, handle rotating coder, signal amplifier, signal poweramplifier, proportional electromagnetic valve, hydraulic element, rudder blade, rudder blade feedback signalling potentiometer and feedback rotating coder. It is characterized by that it adopts AMD80188ES embedded microprocessor as central processing unit, the input end of said microprocessor is equipped with RS 485 interface. Said microprocessor is connected with flash memory of storage control software and electrically-erasable programmable read-only memory for storing control parameters, and two serial ports of said microprocessor have a RS232 interface.

Description

Technical field: [0001] The invention relates to a full-rotation double-blade harbor-use tugboat, in particular to a full-turn double-blade harbor-use tugboat rudder propeller control system. Background technique: [0002] Existing Kamiwa US1401 / 2700 rudder propeller central control system designed and manufactured by Finland Aquamaster Company. The control system consists of a main control circuit board and an auxiliary control circuit board. The main principles are: [0003] After the steering signal and the actual position signal of the rudder propeller are received by the main control circuit board in the control system and processed by the operation and amplification circuit on the circuit board, the corresponding electrical signal is output to The proportional solenoid valve that finally controls the movement of the rudder propeller controls the rudder propeller to rotate to the rudder propeller angle required by the driver. [0004] The auxiliary control circuit bo...

AI Technical Summary

Problems solved by technology

[0006] 1. The parameters of the rudder and propeller control system often need to be adjusted and changed according to the environmental conditions of the tugboat. However, the original design did not consider the problem of changing the control parameters during field use. Generally, the central control unit must be dismantled back to a specific place. It is extremely inconvenient to change, and then put it back on the ship after changing;

[0007] 2. The pulse width adjustment range of the signal output to drive the movement of the rudder propeller is small, 35% to 65%, which causes the control device to not control the hydraulic components smoothly;
