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.
