Abstract

The invention discloses a navigation/flight control computer. The navigation/flight control computer comprises a flight control board, a navigation board, a global positioning system (GPS) positioning system, an onboard height airspeedometer and a combined navigation unit; a main processing chip of the computer is DSP2812; all the units are integrated on a mother board of a host; the flight control board, the combined navigation unit and the onboard height airspeedometer exchange data with one another through an RS422 interface; the navigation board and the flight control board exchange data through a double-port random-access memory (RAM) and are connected with a communication data chain of the GPS positioning system; the GPS positioning system exchanges data with the navigation board through an RS232 interface; the combined navigation unit exchanges data with the flight control board through the RS422 interface; and the data of the units are exchanged with the data of the DSP2812 main processing chip. The navigation/flight control computer is small in volume, higher in precision and complete in function; and navigation control and flight state real-time monitoring in various flight modes can be realized.

Description

technical field [0001] The invention relates to a computer, in particular to a small unmanned aerial vehicle navigation / flight control computer that highly integrates navigation functions and flight control functions. Background technique [0002] Small drones can be used in military reconnaissance, electronic countermeasures, harassment, temptation, early warning and other fields; in civilian use, they can be used in geodesy, meteorological observation, urban environment detection, earth resource exploration and forest fire prevention. [0003] The small UAV flight control system is a comprehensive system with high performance of autonomous navigation, automatic flight control and task management. As the core component of the flight control system, the navigation / flight control computer needs to perform a large number of complex data processing and mathematical operations, and is generally composed of low-power chips. In the traditional flight control system, navigation co...
