This paper combines with Qt software and explains the development of multiple interface boards test device of General Safety Signal Application Platform(GSSAP)based on Embedded Common Plugins(ECP)industrial computer as a hardware platform.The functional modules of the test device are designed by analyzing the functions of multiple interface boards.For the difficulties of the device implementation,including massive interconnection and small resistance test,this paper proposes that summarizing signals of test modules to general adapter cards,and designing adapter cards for each product under test to achieve signal transfer,and testing the small resistance through four-wire method.The test device has the advantages of easy operation,convenient expansion etc.
