The introduction of the data-centered system inter-process communication method increases the reliability and flexibility of the data communication of the software system, enhances the real-time performance of the flight control system to collect analog data, reduces the burden on the flight control computer CPU, and improves the The overall parallel processing capability of the flight control system.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle control, in particular to an onboard computer software system of a small unmanned aerial vehicle. Background technique [0002] With the development of new technologies and new equipment, the development of drones is also accelerating, and various drones have come out one after another. Due to the advantages of UAVs such as maneuverability, small size, low cost, and no casualties, the research and development of UAVs has been highly valued by many countries. In the military, UAVs can be used as aerial reconnaissance platforms and weapon platforms. By carrying different equipment, they can perform tasks such as reconnaissance and surveillance, ground attack, electronic interference, communication relay, target positioning, and effective assessment of attack damage. In terms of civilian use, UAVs are also promising. It can be used in aerial photography, meteorological detection, sur...

Problems solved by technology

[0003] In the past few decades, small UAVs have been widely used in military and civilian fields all over the world. Small UAVs have the advantages of high flexibility, good concealment, and low fuel requirements. They can perform various difficult tasks in harsh, boring, and dangerous 3D environments. Now the design of their onboard computer software systems has become a limitation. The main obstacle for the development of small UAVs in the direction of full autonomy, multi-tasking, and high security. Like most embedded systems, UAV onboard computers have limited size and limited resources, but they are required to be able to meet various complex conditions and real-time applications. Therefore, the development of its software system is a complex process. In the design process of the computer software system onboard the small UAV, the key issues to be considered are: (1) How to design a flexible and scalable software system architecture to meet the requirements of task diversity and the increasingly wide range of sensor processing requirements; (2) The wide application of UAVs leads to more and more flight accidents, and the frequent flight accident rate leads to the limitation of UAVs in military and civilian fields, so how to ensure the safety of UAVs in design and reliability are also an important task in the design of airborne computer software systems
