Aiming at the problem that flight data recorder taken aircraft directly as testing signal resource in the process of development and debugging of the flight data recorder is very difficult, the flight data signal generator based on embedded system is designed, which purpose is to simulate the status signal of aircraft and each component of aircraft during flight, providing test signal source for flight data recorder. Interactive interface was designed on PC by LabVIEW, which was used for setting parameter values of each signal; STM32 microcontroller received the parameter value and controlled each generating module to generate electric signal. All generating modules link with the Bus network, and the network will be easy to increase or decrease generating module. Experiment results show that the flight data signal generating system can simultaneously generate 138 signals, including analog, digital, synchronous, frequency, ARINC429 bus signals etc, and can work stably.
