Embodiment Construction

[0022] The present invention will be further described below in conjunction with drawings and embodiments.

[0023] Such as figure 1 , The dual-redundancy valve control system is composed of a dedicated controller and a motor driver, which can detect the working status of the valve, automatically switch the working mode and receive application system instructions. The valve is driven by two stepping motors, which drive the slide valve and the rotary valve respectively. Motor 1 drives the spool valve action of the double redundancy valve, and motor 2 drives the rotary valve action of the double redundancy valve, and the two motors are driven by their respective drivers. The driver can provide the power for the stepper motor action, and at the same time support the subdivision of the control pulse. The digital controller is the core of the system. On the one hand, the controller sends control pulses to the stepper motor driver to command the action of the slide valve or rotary...

Abstract

A dual-redundancy reversing valve control system for a ship's hydraulic steering gear, which is composed of a dedicated controller, a motor driver, etc., can detect the working state of the valve, automatically switch the working mode, and receive application system instructions. The control system uses a stepper motor to replace the traditional solenoid valve to drive the dual-redundancy reversing valve of the steering gear. The controller can detect the relevant state of the valve in real time and precisely control the stepper motor to obtain excellent control performance.

Description

technical field [0001] The invention relates to a double-redundancy reversing valve control system for a ship's hydraulic steering gear, which is suitable for the mechanical field. Background technique [0002] As the key equipment to control the ship's course, the ship steering gear's reliability and safety will directly affect the safety of navigation. In order to ensure the safety of navigation, my country's "Code for Sea-going Steel Ships (2009)" stipulates that the main steering gear must have more than two sets of power equipment. When one of them fails, the other set should be able to quickly put into work. For the valve-controlled steering gear, it is the reversing valve that is frequently used and prone to failure. From a functional point of view, the reversing valves currently used in ship hydraulic steering gears are slide valves and rotary valves, but they are all single-residual valves. Ordinary steering gear reversing valves mostly use solenoid valves as pilo...
