The power distribution equipment, the key equipment in certain unmanned aerial vehicle (UAV), is in charge of the power distribution management and the signal conversion of airborne sensors, and must be comprehensively tested before the trial flight of UAV to ensure the flight safety. The automatic test method for the equipment is researched and an automatic test system is developed to meet the test requirements on the basis of PC/104 bus and FPGA. For sake of testing the signal conversion circuit of the distribution equipment, excitation signals such as switch, resistor, voltage and pulse signals are generated by the test system and the error of these excitation signals is analyzed. A rule-based fault diagnosis expert system is developed to locate the fault circuit of the distribution equipment. The test result shows that the designed test system can operate stably and reliably. The application of the test system will bring a great benefit for both military and economy applications.
