一种1394子卡测试设备的设计与实现OA

The 1394 daughter card is a circuit board that implements the IEEE 1394B bus protocol.During its production process,extensive testing is required to determine whether it meets quality standards.Traditional manual testing methods suffer from low efficiency and inadequate test coverage.This paper proposes a design scheme for a test equipment specifically for the 1394 daughter card.The test equipment is divided into several parts such as an industrial control computer,a stimulus source,a product test terminal,and a power supply.The design of the test equipment is introduced from aspects such as hardware,structure,and software.This equipment enables the testing of the Remote Node function of the 1394 daughter card.Practical testing and environmental trials demonstrate that the test equipment is reliable in both functionality and performance,and it is easy to use,has friendly human-computer interface,and offers good practicality.It holds significant importance for the testing of avionics networks.
