Avionics system suitable for multi-purpose unmanned aircraft

Abstract

The invention discloses an avionics system suitable for a multi-purpose unmanned aircraft. A 1553B dual-redundancy bus framework is adopted in the avionics system. The avionics system consists of a main processor unit, a universal interface unit, a 1553B bus, a mass memory, an airborne monitoring terminal, a task load, an execution mechanism and a sensor assembly. The devices have the connection relationships that: the main processor unit, the universal interface unit, the mass memory, the airborne monitoring terminal and the task load are connected with the 1553B bus through a 1553B special electric connector, and the 1553B special electric connector serving as a bus module connects all the devices attached to the bus together; a steering engine controller is connected with the universalinterface unit through an RS422 interface; and the sensor assembly is connected to the universal interface unit through interfaces of serial RS422 / RS232 / RS485, an ARINC429 bus, a CAN, analogue AD / DA and discrete DIO and the like. The avionics system has the characteristics of strong multi-task expandability, multi-redundancy high reliability, rich data interfaces and strong calculation and processing capabilities, and can well meet the application requirement of 'one platform and multiple purposes' of the unmanned aircraft.

Description

(1) Technical field [0001] The invention relates to an avionics system suitable for multi-purpose unmanned aircraft, belonging to the technical field of avionics systems. (2) Background technology [0002] In military applications, in addition to gradually serving as comprehensive tasks such as reconnaissance, early warning, surveillance, command, control, communication, and mapping, unmanned aerial vehicles can also cooperate with manned combat aircraft to seize air supremacy, perform ground attack missions, and conduct damage assessments. And perform the dual tasks of information soft killing and firepower hard strike. Unmanned aerial vehicle system includes aircraft platform, integrated avionics system, measurement and control and data transmission system, ground support system and mission load. [0003] In order to meet the complex and diverse mission requirements of UAVs, the avionics system, as the enabling unit of the whole system, should have outstanding performance...

AI Technical Summary

Problems solved by technology

[0004] At present, there is no structural standard for the avionics system of unmanned aerial vehicle, and the avionics system is designed for the corresponding platform, with poor scalability and portability, and it is difficult to adapt to the rapid growth of demand for unmanned aerial vehicles
