Embodiment approach

[0023] The specific connection between the STM32 processor as the first processor 11 and the DSP28335 processor as the second processor 12 and the dual-port RAM is generally as follows figure 2 shown. Dual-port RAM adopts IDT71321 chip. Under the connection mode of the dual-port RAM of this embodiment, the two processors judge whether they can write through the BUSY output of the IDT71321 chip. That is, when the left and right ports perform data access to different address units, both BUSYR and BUSYL are at high level, indicating that the memory is working normally. When two ports perform data access to the same address at the same time, the BUSY corresponding to the port in front of the request is high, indicating that data access is allowed, and the BUSY corresponding to the other port is low, indicating that data access is prohibited. Since the internal arbitration logic of the dual-port RAM does not make the BUSY signal low at the same time, it can ensure that a port co...

Abstract

The invention discloses a flight control panel based on a bi-processor configuration. The flight control panel comprises a flight control sensor, a remote control signal receiving unit, a wireless data transmission unit, an executing mechanism, a first processor, a second processor and a dual-port RAM. The first processor and the second processor are respectively connected with two ports of the dual-port RAM. The flight control sensor, the remote control signal receiving unit and the wireless data transmission unit are connected to the first processor. The second processor is connected to the executing mechanism. The first processor obtains the real-time data by an interruption means and conducts corresponding processing, and real-time data needed for flight control are stored into the dual-port RAM. The second processor calculates based on the real-time data required for flight control and stored in the dual-port RAM, and then the calculated control data for each rotor motor is assigned to the corresponding rotor motor through the executing mechanism. The flight control panel improves the stability and reliability of an aircraft by allocating the calculation of the flight control data to a dedicated processor.

Description

technical field [0001] The invention relates to flight control of unmanned aerial vehicle. Background technique [0002] The flight control of the UAV is completed by the flight control board. The processor is mounted on the flight control board. The processor of the UAV needs to complete the collection of attitude reference system data and GPS data, calculate the attitude information and position information in real time, and also complete the calculation of the control law and the interaction with the data of the ground measurement and control station. That is to say, the data processing capacity of the UAV processor is very large. On the other hand, drones have very high requirements for real-time data processing. For example, UAVs are required to be able to respond to the instructions issued by the remote control in real time. For abnormal flight attitudes caused by abnormal flight environments, UAVs can respond in a timely manner and make timely remedial treatment. ...
