AI summary

The invention discloses a semi-open source control system for unmanned aerial vehicles and a design method thereof which is constructed single-chip multi-core processor and shared register on a UAV. A main processing core of the single-chip multi-core processor is built with a semi-open source control module configured to control the UAV. The semi-open source control module includes a closed source control function module and an open source control program module. The closed source control function module includes data processing function module, communication function module, flight control function module and hardware setting function module, enabling the semi-open source control module to perform power management, ground communication, aviation sensing, flight control, navigation calculation and flight record information processing of the UAV. A secondary processing core of the single-chip multi-core processor is built with user application programs enabling users to program working task application programs according to their required tasks, and the working task application programs are composed with the open source control program module through the shared register. Thereby, an autopilot program is capable to be built in the main processing core and flight status and waypoints saved in shared registers, users can develop other application programs through other processing cores for navigation or Al computing, then achieve the aims of increasing the stability of system software and hardware, reducing space and weight, and reducing current consumption and cost.
