Remote display of flight deck information from a legacy display system

摘要

A liquid crystal display (LCD) only Engine Indicating and Crew Alerting System (EICAS) for Boeing 757 and Boeing 767 aircraft which utilizes Engine Alert Processors from a previously certified CRT EICAS and minimizes changes in hardware and software design by simultaneously generating both cathode ray tube (CRT) drive commands and LCD drive commands while only using the LCD drive commands for display of EICAS information during flight.

主权项

1. An engine indicating and crew alerting system (EICAS) comprising:
a plurality of engine alert processors (EAPs), each EAP comprises an input/output controller (IOC); an input/output buffer random access memory (RAM), a signal processor (SP), shared RAM, and a display generator (DG), wherein said SP is configured with software to pack graphics display data, where said graphics display data is representative of information provided to and used by the DG for generating cathode ray tube (CRT) drive commands, said SP further configured with software to pack internal data and DG data into ARINC (Aeronautical Radio INC.) 429 labels for transmission; one or more graphics generator units (GGU), the one or more graphics generator units configured to receive internal data and DG data with ARINC 429 labels, the one or more graphics generator units being configured to generate LCD drive commands from the internal data and the DG data with ARINC 429 labels, wherein the one or more graphics generator units create the LCD drive commands in accordance with a particular EICAS format based upon the internal data and DG data with ARINC 429 labels; and a display device comprising a rectangular array of individually addressable pixels which receive said LCD drive commands, which do not include and are not created using said CRT drive commands, where said LCD drive commands are provided via a non-electron beam connection with said GGU.
