Reconnaissance/attack integrated unmanned aerial vehicle flight control system multi-serial-port router

Abstract

The invention relates to a reconnaissance / attack integrated unmanned aerial vehicle flight control system multi-serial-port router, which comprises a unified power supply module, a core processor, an SPI-to-four-serial-port communication chip, TTL-to-232 signal level conversion chips and TTL-to-422 signal level conversion chips. Communication level types of SPI-to-four-serial-port four child serial ports are selected according to level types of external transmission signals, and the TTL-to-232 signal level conversion chips or the TTL-to-422 signal level conversion chips are selected and welded according to the types; three child serial ports of the core processor serve as one TTL level serial port backup serial port and two 232 communication level backup serial ports; and the core processor receives information transmitted by peripheral equipment through one or more series ports serving as a receiving end, and carries out integration on the information and sends the integrated information to one or more series ports serving as a sending end, which transmits the information to other peripheral equipment, thereby realizing a one-to-many, and many-to-one communication transmission mechanism. The router can serve as a transmission center for communication between devices on unmanned aerial vehicles or ground.

Description

technical field [0001] The invention relates to a multi-serial-port router of an integrated unmanned aerial vehicle (UAV) flight control system, which can provide independent and reliable communication support for increasingly extensive UAV airborne equipment and ground equipment. Background technique [0002] As a new type of aircraft, unmanned aerial vehicle provides the possibility for anti-shock and anti-overload design, increasing flight time and range, improving take-off and landing flexibility, improving flight control maneuverability, reducing cost and risk, etc. The application and promotion of various fields, such as a kind of surveillance drone, the airborne equipment is also increasing. station, on-board flight control system and ground station control system, etc. The limited measures generally adopt the working mode of independent radio communication.

Problems solved by technology

The limited measures generally adopt the working mode of independent radio communication. The on-board equipment is equipped with independent signal level conversion modules, the communication between the on-board equipment and the ground equipment, and a pair of radio communication between a pair of equipment. While the operational requirements and precision requirements of drones are increasing, the increase of these auxiliary equipment has brought a negative effect on the "small, fast, and flexible" characteristics of drones, and the communication inspection of equipment is also very cumbersome.

Based on the characteristics of the portable work of the UAV, the present invention proposes a multi-serial port communication router design for the UAV flight control system, which can solve the communication problem between the on-board equipment or with the ground equipment. , The principle of complete function set can meet the needs of different signal level conversion and communication, greatly reducing the quality of UAV auxiliary equipment
