specific Embodiment approach

[0029] The structure of the airborne electronic equipment components shown in Figure 1 makes it possible to complete the automatic driving of the aircraft, provide stall protection, and complete the data collection and centralized maintenance of these equipment components. To this end, it contains five key display devices 3-7; two housing units 1, 2 housing two identical modular processing components IFC1 and IFC2 (Integrated Flight Box); two main reference systems 8, 9, They are the sensors that transmit critical data, and each includes, for example, an AHRS (Attitude Orientation Reference System) attitude unit and an ADC (Air Data Computer) system for collecting and processing data related to the air outside the cabin, enabling short-term Acquisition of flight parameters; two engine parameter measuring devices FADEC1 and FADEC2 (full authority digital engine computer) 10, 11; a set of actuators 12 and non-critical sensors for transmission of non-critical data such as sensors,...

Abstract

A modular architecture for electronic equipment. Data-concentration modules, processing modules and display devices are interconnected by data-transmitters with sensors, measuring instruments and detectors. The data-concentration modules concentrate only the data which is not critical for the industrial process. This data is transmitted to other modules by a multi-receiver serial bus. The other modules directly receive the critical data which is routed by separate, respective serial digital links between, on the one hand, display devices and functions controlling the processes which are distributed in the process modules, and, on the other hand, sensors, measuring instruments and actuators.

Description

technical field [0001] The invention relates to the modular construction of a set of electronic equipment components which makes it possible to control an industrial process requiring high operational safety. Background technique [0002] It applies especially, but not exclusively, to the airborne electronics components that perform various flight control functions. Obviously, the current development of such equipment is increasingly aimed at the automation of flight control tasks, especially the automation of aircraft piloting. This trend has resulted in increasingly complex, bulky, energy-consuming, expensive, and difficult-to-maintain equipment. [0003] To solve this problem, it has been sought to integrate and make these devices into modules having a standard size. For this reason, a structure has been proposed which puts different electronic modules together in an electronic box or rack. These modules collect raw information from sensors and other onboard equipment,...
