The present invention relates to a data concentration unit which enables to convert sensor and discrete input/output warning signals coming from engine, transmission, fuel, electric and hydraulic systems on AH- IS helicopter into digital data, and to be transmitted to the mission computer of an aircraft through MIL- STD-1553 data bus for digital display on a multi-function display.
Background of the Invention Sensor and discrete input/output warning signals coming from engine, transmission, fuel, electric and hydraulic systems of aircrafts are directly connected to analog and/or mechanical indicators in pilot/copilot cockpits. However, these data are not suitable to be directly used in Multi-Function Displays that are being used in cockpits of modern aircrafts.
Cockpit configurations comprising analog/mechanic indicators require the pilot to follow separate indicator for each platform data of the aircraft. Furthermore, each one of the indicators should be tested and calibrated in certain intervals in terms of flight safety. In addition, since it is very difficult to repair several air platforms, acquiring indicators that have to be changed can be very difficult of impossible. For this reason, aircraft may have to wait in completely or partially unusable way during supply/repair processes of the indicators. All these problems and requirements cause extra spare part, labor and maintenance costs. Therefore both reducing sustenance and maintenance costs of the aircraft, and the pilot following up the platform data in an ergonomic and easy way get difficult. The Problems Solved with the Invention
The objective of the present invention is to provide a data concentration unit which enables to control all information exchange on the air platform from a single center by converting sensor and discrete input/output warning signals coming from engine, transmission, fuel, electric and hydraulic systems. Therefore, weight and wiring load created by analog/mechanic indicators provided in the cockpit for each platform data and also the material supply/maintenance/labor costs are eliminated.
The inventive data concentration unit is designed compatible with the environmental requirements determined by military standards (MIL-HDBK-5400, MIL-STD-810, MIL-STD-704 and MIL-STD-461), furthermore the former air platforms having analog cockpit can be transformed into digital cockpit used in modern air platforms of today by means of the data concentration unit, and it can be enabled that the additional functions are integrated in a fast way by means of software design realized with open architecture techniques.
