摘要
The present invention relates to a built-in test (BIT) processing device of a flight control system for an unmanned aerial vehicle (UAV) and a method for controlling the same. The BIT processing device of a flight control system for a UAV comprises: an actuator module to drive control surfaces for various aircraft operation and aircraft electronic equipment included in a UAV, carry out a flight or a virtual BIT of the UAV, and detect and output status information according to a flight control signal of a flight control computer; a memory management module to check whether a virtual BIT request command signal is received from a control device at a remote site through the flight control computer and change the value of a certain address area of a memory according to the virtual BIT request command signal; a boot loader module to continuously check and output the value of the certain address area of the memory; and a control module to carry out the virtual BIT of the UAV only when the UAV is not actually operated, after checking the actual flight of the UAV if the virtual BIT request command signal is checked through the boot loader module. According to the present invention, if a BIT carry out signal is received during the operation of a flight control software for the UAV, the running of the BIT is decided by determining whether the UAV is actually operated. Therefore, a BIT carry out command signal that may be applied during the actual operation of the aircraft can be safely processed according to whether the UAV is actually operated, thereby optimizing the safe operation of the UAV.
