An automatic test method for power equipment io plug-in suitable for assembly line production

Abstract

The invention discloses a power device IO plug-in automatic test method suitable for pipeline production. A database, a computer, a tester, an auxiliary device and the like are provided; the databaseis used for barcode identification and test data storage; the computer is used for test management and fault positioning realization; the tester comprises a main control board, a backplane, a terminalconversion matrix, a backplane interface conversion module, a pin bed and the like; the terminal conversion matrix achieves automatic test wiring by switching a working bus; in the case of output test, main / standby double-input voltage sampling is used, and comparison error proofing is carried out; interface or level conversion is carried out through the backplane interface conversion module so as to meet requirements of a to-be-tested plug-in; and IO test is regularized to two steps of setting output and comparison input, the universality and the extensibility of an IO plug-in test logic areensured, and flexible pipeline production requirements can be well met.

Description

technical field [0001] The invention belongs to the field of automatic testing of electric equipment, and in particular relates to an automatic testing method for an IO plug-in of electric equipment suitable for assembly line production. Background technique [0002] Substation secondary equipment manufacturers are exploring the design and promoting the production of intelligent manufacturing lines. Plug-in automation testing is an important link in the production of intelligent manufacturing lines. When the existing plug-in is tested, it is generally used to test the external debugging harness of the terminal. If there is a new plug-in, the debugging harness needs to be customized, so each plug-in needs to design a corresponding wiring harness. The debugging wiring harness has poor versatility and difficult management. Due to the different forms of IO plug-in backplane terminals, it is usually necessary to design a dedicated test backplane and chassis. Each plug-in needs ...
