Automatic test system and method for flight time module

The invention provides an automatic test system and method for a flight time module. The system comprises main control test equipment, a guide rail, the flight time module, a reflector module and a light source module, the main control test equipment is electrically connected with the guide rail, the flight time module, the reflector module and the light source module respectively; the main control test equipment is used for switching the reflectors with different reflectivity through the reflector switching device, adjusting the illuminance of the light source emitting light through the controller for controlling the illuminance of the light source, controlling the flight time module to move on the guide rail so as to adjust the distance between the flight time module and the reflector, and starting the flight time module so as to adjust the illuminance of the light source emitting light through the controller. Histogram data is collected. By adopting the method and the device, the flight time module can be
