Electro-hydraulic proportional twin rudders follow-up synchronization operation controlled system

Abstract

The invention discloses an electric hydraulic proportion twin rudder following and synchronous operation control system, which comprises an autopilot control system, a left rudder machine power/signal control box, a left rudder machine control box, a left rudder machine system, a left rudder angle signal feedback device as well as a right rudder machine power/signal control box, a right rudder machine control box, a right rudder machine system and a right rudder angle signal feedback device. The left rudder machine system and the right rudder machine system adopt a hydraulic rudder machine control system which uses a variable hydraulic pump and a proportional electromagnetic valve as a control core. In the left rudder machine system and the right rudder machine system, two hydraulic pumps drive two sets of oscillating oil cylinders to drive a tiller; the autopilot control system is a self-adaptive autopilot control system. The control system has the advantages that as the proportional valve and a variable pump are adopted for control, the mechanical shock of the device is reduced so as to be convenient for maintenance; since the use of the proportional valve and steering signals are continuously variable, the continuously stable startup and stop of the whole system are realized to effectively reduce the mechanical shock, thus not only protecting the mechanical system of the rudder machine, but also being beneficial to reducing the mechanical shock of the tail structure; furthermore, the use of the variable hydraulic pump and the proportional valve meets the requirements of various single-control indexes and the synchronous operation for steering the twin rudders.

Description

technical field [0001] The invention relates to an operation control system, in particular to a steering gear operation control system. Background technique [0002] At present, the ordinary dual rudder control system is mainly composed of the autopilot control system and the hydraulic steering gear system (mainly including: hydraulic motor quantitative pump, solenoid valve, oil cylinder, etc.). The oil cylinder supplies oil to drive the rudder to work. Because the control signal of the system is a switch signal, there are only two states of fuel supply and non-fuel supply to the drive cylinder, and the fuel supply is constant. Under this working condition, there are the following problems: 1. When the steering starts and stops, the system has a large impact, severe vibration, and large system loss; 2. When the two rudders are operated synchronously, due to the quantitative control, it is easy to generate synchronous vibration and cause serious damage. Damage the steering ...

Problems solved by technology

Under this working condition, there are the following problems: 1. When the steering starts and stops, the system has a large impact, severe vibration, and large system loss; 2. When the two rudders are operated synchronously, due to the quantitative control, it is easy to generate synchronous vibration and cause serious damage. Damage to the steering gear system, or the error of the synchronous rudder angle is too large to reduce the rudder effect
