Full digital solid-state power distribution management system and method for unmanned plane

Abstract

The invention discloses a full digital solid-state power distribution management system and method for an unmanned plane. A solid-state power controller is used for power distribution. Power distribution management includes power distribution control management as well as status monitoring and automated reset management of the unmanned plane. The power distribution management adopts different power distribution management methods for three modes (key load, important load and common load) decided according to airplane safety, and controls through in three ways: a comprehensive management computer, a flight control computer and a comprehensive inspection device. The status monitoring and automated reset management transmits status data of a power distribution device to the comprehensive management computer, which forwards related information to a flight data recorder, a measurement and control system and the comprehensive inspection device. If a fault happens due to an external circuit or device, or external interference induces abnormal power failure, the power distribution device automatically resets a fault circuit.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle power supply technology, in particular to an unmanned aerial vehicle all-digital solid-state power distribution management system and a power distribution management method. Background technique [0002] As an important component of the aircraft, the power distribution system is used to transmit and distribute the electrical energy provided by the generator to the various electrical equipment of the aircraft, which is of great significance for the flight safety and autonomous flight of the UAV. Because in each stage of UAV flight, dynamic power distribution needs to be performed according to the working state of the aircraft and the flight stage. For example, according to the capacity and load status of each generator, the load should be reasonably distributed to balance the entire system; It is necessary to complete fault location and isolation, realize system reconstruction, realize uninterrupted po...

Problems solved by technology

However, the above-mentioned patent still adopts the traditional power distribution management method. Due to the weak management function and the small amount of information provided by the system, the autonomous flight performance of the UAV is poor, and if a single point of failure occurs, it cannot be quickly located and processed. information
