Modularized UAV (unmanned aerial vehicle) flight control and management system

Abstract

The invention relates to the unmanned aerial vehicle field and more particularly to a modularized unmanned aerial vehicle flight control and management system. The system comprises two flight control and management computers and at most fourteen interface modules. The bus module comprises a FlexRay bus A / B channel, two active star shaped connectors and as many as 16 bus connectors with a start shape and bus type mixed topology structure. Each flight control and management computer is provided with a FlexRay bus interface and four channels of discrete quantity specialized to acquire the address coding information; each interface module is provided with a FlexRay bus interface and four channels of discrete quantity specialized to acquire the address coding information; the flight control and management computers and the interface modules are connected to the FlexRay bus through the bus and according to the address coding information, its functional areas are determined and corresponding software is run. The invention provides an unmanned aerial vehicle flight control and management system with good interchangeability and maintainability.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a modularized unmanned aerial vehicle flight control and management system. Background technique [0002] At present, the flight control and management system of the UAV generally realizes cross-linking with other devices through the RS422 or RS485 bus. This method generally takes the flight control and management computer as the core, adopts a star layout, and is reliable for the flight control and management computer It has high requirements on performance and interface performance, and it is not easy to realize redundancy control, and it is not easy to expand the system. Especially for large unmanned aerial vehicles, due to the large number of equipment and scattered, the airborne cables are many and heavy, and the flight control and management computer is difficult to effectively manage or the burden is too heavy.
