Based on the power management system of a medium-sized unmanned helicopter, an automatic test system is designed and implemented. Aiming at the shortcomings of ordinary test methods, such as low efficiency, poor accuracy and poor security, this paper discusses the design and implementation of an automatic test system for power management system from both software and hardware aspects and give the specific functions and implementation methods. The embedded system based on STM32F427 is adopted, and the host computer software runs on the Windows platform and is developed in the Microsoft Visual studio integrated development environment. The automatic test system realizes the full-function automatic test of the communication of the power management system, power supply control, voltage detection, current detection, power supply abnormal handling, and power consumption abnormal handling. Compared with ordinary detection methods, this automatic test system shortens the test time, improves the test efficiency and accuracy, and ensures the safety of equipment and personnel.
