Universal small unmanned aerial vehicle dual-core flight control computer and control method

Abstract

The invention discloses a universal small unmanned aerial vehicle dual-core flight control computer and a control method. The computer comprises an airborne sensor system, a wireless communication module, master and slave flight control computer bodies, a dual-port RAM, a first multiplexer switch and a second multiplexer switch, wherein the master and slave flight control computer bodies send heartbeat detection signals to each other through a CAN bus to judge whether failures exist, the first multiplexer switch is controlled to connect the airborne sensor system and the wireless communication module to the master or slave flight control computer body according to a judgment result, and a control signal is obtained through calculation according to received and decoded unmanned aerial vehicle state information and a wireless control instruction by the master or slave flight control computer body; the second multiplexer switch is controlled according to a judgment result to output the control signal of the master or slave flight control computer body, so that the computer is made to work in the master-slave load sharing mode or independent sharing mode. The dual-core flight control computer is high in operation speed, large in data throughput and capable of guaranteeing continuous operation of a system.

Description

technical field [0001] The invention relates to a dual-core flight control computer and a control method for a general small unmanned aerial vehicle, belonging to the technical field of unmanned aerial vehicle flight control. Background technique [0002] The research and development of small unmanned aerial vehicle (UAV) has been enduring in the field of aviation for a long time, the main reason is that it has incomparable advantages in terms of size, weight and cost, etc. that other large and medium-sized aviation vehicles can't match. At present, with the continuous development of computer technology, aviation technology and control theory, the intelligence level and comprehensive capabilities of small UAVs are gradually improving. These characteristics determine that in the future, small UAVs can not only have some functional characteristics of conventional UAVs, Because of its unique advantages such as small size, light weight, low power consumption, and low cost, it ha...

Problems solved by technology

[0004] Moreover, at present, small UAVs generally use a single CPU for flight control. The task load of a single CPU is large, the processing speed is slow, and the interface resources of the system are few. Especially when the CPU fails, the UAV cannot continue to perform flight tasks.
