The starter box as the key part of plane starting electric control system is used to let the engine work properly by controlling the starting accessories working cooperating by sequence logic. The composition and the controlling sequence logic analysis of the starter box are introduced and the design of auto test equipment for the starter box based on ATE hardware platform is also given. Some technologies such as bus program controlling instruments and GUI test software are applied to realize the on-off time parameters measurement of electronic time controller, time sequence logic functions verification of starter route and faults diagnosis. The equipment performance is validated by the army in the following respects:greater efficiency, accurate test results, excellent stability, easy to operate and friendly graphical user interface.
