Bus communication based small unmanned aerial vehicle control system

Abstract

The invention relates to a bus communication based small unmanned aerial vehicle control system. The bus communication based small unmanned aerial vehicle control system comprises data transfer radios, bus sensors, flight control computers, a power supply system, steering engines, a task device and a data recorder, wherein the data transfer radios use a CAN (controller area network) bus network as a communication foundation and conform to a unified communication protocol, and the data transfer radios, the bus sensors, the flight control computers, the power supply system, the steering engines, the task device and the data recorder are connected to interfaces of the CAN bus network respectively and are in both-way communication with the same. The system has the advantages of good instantaneity, high stability, high rate, easiness in contact expansion and low cost.

Description

Technical field: [0001] The invention relates to a small unmanned aerial vehicle, especially the technical field of its control system. Background technique: [0002] Unmanned aircraft is an unmanned aircraft controlled by radio remote control or its own program. Compared with manned aircraft, it has the advantages of small size, low cost, convenient use, and low environmental requirements. It is widely used Used in military, electric power, surveying and mapping, forest pest control and fire prevention, exploration, monitoring and related scientific research systems. [0003] The traditional small UAV system usually consists of remote control receiver 34, flight control computer 39, steering gear 35, 36, 37, digital transmission station 33, sensor 38, and battery system 40, and usually adopts the framework of wireless remote control aircraft model, namely All peripherals are connected on the flight control computer 39, and the whole system is centered on the flight control...

AI Technical Summary

Problems solved by technology

[0004] 1. The system is not easy to expand, and the traditional UAV system basically cannot be expanded after the design is completed;

[0005] 2. The interface is not uniform, there are many types of interfaces, and it is difficult to guarantee the reliability of the connectors of the aircraft model;

[0006] 3. The equipment in the system, except the digital transmission station, transmits signals in one direction, which cannot reflect the status of each equipment in the system in real time;

[0007] 4. Lack of system design ideas, there are usually multiple wireless transmission systems in the system, which may interfere with each other;

[0008] 5. Single host system, all information processing depends on the flight control computer, the host processing pressure is high;

[0009] 6. It is difficult for the system to achieve redundant backup of equipment, and equipment failures cannot be isolated
