The test is an important part in the development process of complex equipment. The data generated during the test has important significance for the verification of complex equipment and the design and development of subsequent products. Aiming at the characteristics of variable test equipment types and bus protocols, an integrated data acquisition system for test sites was designed to meet the requirements of various bus data and video data collection, in order to improve the efficiency of test data collection, and reduce various types of tests. The experirment system tests verified the effectiveness of the proposed design of integrated data acquisition system can can provide reference of building a complete test and test system for test-sites .
