Bus-type adjustable pitch propeller united controller

Abstract

The invention discloses a bus-type adjustable pitch propeller united controller, comprising an electronic control centre, a central control room console, a driving control room console, a signal input / output centre and a liquid display. The bus-type adjustable pitch combined controller is characterized in that the electronic control centre adopts union operation of a FRAM chip and a FLASH chip, each saving information is firstly stored in a FRAM ferroelectric chip, after batch information is achieved, the batch information is again written in the FLASH chip in one step. The invention automatically saves dynamic system real-time state information of screw pitch, rotating speed, host load, and the like, automatically records real-time control output information sent to a pitch angle adjusting device, a host speed regulating device and a host control device, records an operation instruction information function sent by a driver at the central control room console or at the driving control room console and saves effective more than 540,000 information so as to realize massive data storage. The recorded spot data is the precondition and the important evidence for realizing correct analysis, positioning, exclusion and modification of faults of ships.

Description

technical field [0001] The invention relates to the field of ship control, in particular to the control technology of ship adjustable pitch propellers, in particular to a bus type controllable pitch propeller combined controller. Background technique [0002] Adjustable pitch propellers (also known as controllable pitch propellers) steplessly adjust the pitch angle of the propeller blades through the electro-hydraulic control system, thereby realizing the "stepless speed change" of the ship's power transmission, thereby improving the control performance of the ship; by adjusting the propeller blades The pitch angle can realize the optimal matching of speed, load and engine working conditions under specific working conditions, thereby improving the fuel efficiency of the engine and reducing energy consumption; The system can automatically reduce the pitch angle of the blades, thereby reducing the load of the main engine, and achieving the function of protecting the main engin...

AI Technical Summary

Problems solved by technology

[0003] The existing controllable pitch propeller system only meets the control requirements of the pitch and speed of the ship, and does not have the function of recording information such as state parameters, control output, and operation instructions of the controllable pitch propeller. The preconditions and important basis for correction are the main indicators for analyzing and judging the ship’s operating conditions and system status, and are an important system function that is urgently needed and urgently needed by the ship safety guarantee system
