Loose coupling integrated flight display

Abstract

The invention discloses a loose coupling integrated flight display. Internal modules of the display comprise a GCPU module, a GPM module, a DCPU module, an IOM module, an SPM module, a mother board, aPS module, a display screen and a box body. The PS module supplies a voltage required by normal work of the modules. The DCPU module, the IOM module and the SPM module are connected through a motherboard local bus, thereby carrying out data exchange. The DCPU module is taken as a bus controller. The IOM module and the SPM module are taken as local bus slave devices. The DCPU module and the GCPUmodule carry out the data exchange through an Internet interface. The DCPU module, the IOM module and the SPM module form a data collection processing function unit. The GPM module is mounted on the GCPU module in a form of a sub-card, and a comprehensive displaying processing function unit is formed. Displaying information generated by the unit is displayed on a displaying screen. The data collection processing function unit and the comprehensive displaying processing function unit work independently through adoption of high performance processors and are interconnected through a serial bus,so a loose coupling structure is formed. A redundant system can be formed by double displays.

Description

technical field [0001] The invention belongs to the technical field of computer hardware design, in particular to a loosely coupled integrated flight display. Background technique [0002] The flight display is the core functional unit of the integrated cockpit display and control of the helicopter. It has powerful data processing capabilities, rich interface configurations and high-resolution graphic displays. During the real-time flight and ground maintenance of the aircraft, it provides flight parameter information, attitude information, navigation information, warning information, equipment working status information and man-machine operation control interface, which enables the pilot to observe and control the aircraft flight attitude and real-time status in a comprehensive and timely manner. Improve the pilot's control ability and flight safety. [0003] Usually, the flight display is connected with airborne equipment such as GPS navigation system, air data system, he...
