AN AVIONIC CENTRAL CONTROL COMPUTER
Field of the Invention
The present invention relates to an avionic central control computer which is designed to control target detection and weapon, electronic warfare, navigation, tactical data transmission and communication systems integrated on an aircraft, to perform mission and flight management, to manage display presentation and to supervise all information exchange on the platform from a single center.
Background of the Invention In applications known in the state of the art, the management of the avionic and weapon systems are provided via distributed architecture. Within this scope, target detection and weapon, electronic warfare, navigation, tactical data transmission and communication system are communicated through defined data buses via more than one computer. In addition to this, these applications do not have open architecture hardware and software design.
Realizing target platform (helicopter, plane, etc.) functions in distributed architecture design is controlled by more than one unit. In this case, the synchronization and the back-up statuses of the controlling units make the system architecture complicated. Furthermore, the control of the messages and statuses of the sensors and other units coming from the platform by the discrete computers increases the platform cable connection and weight.
In design of distributed architecture, more units should be backed up during maintenance/repair stage. Hardware/software changes in more than one unit are
required in order to realize the functions to be newly added to the platform, and realizing these changes in a coordinated way and verifying them increase the cost.

The control of the statuses and the messages of the sensors and other units coming from the platform by central computers instead of discrete computers decrease platform cable connection, and thus the weight of the cables to be placed on the platform.
Another objective of the present invention is to provide an avionic central control computer which enables to integrate additional functions swiftly in the future by means of the design realized with open architecture techniques. The inventive avionic central control computer can be used only with software change in air platforms wherein similar system integrations are performed.
Furthermore, the inventive avionic central control computer is developed compatible with environmental requirements determined by military standards (MIL-HDBK-5400, MIL-STD-810, MIL-STD-704 and MIL-STD-461).
