Testing device control system for detecting testing device failure

A testing device control system comprising:

• a plurality of pallets for carrying a product each, each of said plurality of pallets having a connector for electric connection to the product carried;
• transport means for transporting said plurality of pallets;
• a plurality of automatic testing means furnished along said transport means;
• a plurality of automatic connection means for automatically connecting said plurality of automatic testing means to the connectors of said plurality of pallets;
• common storage means containing a testing item file, a detected testing means failure file, a detected pallet failure file and a testing means failure control file;
• a host computer connected to said plurality of automatic testing means and to said common storage means;
• first defect item writing means for writing to said detected testing means failure file for each automatic testing means the defect items of said product detected by said plurality of automatic testing means;
• first count writing means for counting the number of the same defect items detected by the same automatic testing means and for writing the defect item count to said detected testing means failure file, said first count writing means including means for canceling said defect item count when different defect items detected by said same automatic testing means are written to said detected testing means failure file by said first defect item writing means, and for writing to said detected testing means failure file the updated defect item count of said different defect items;
• first count setting means for setting a desired count;
• failure information writing means for writing failure information about any automatic testing means to said testing means failure control file when said defect item count exceeds the count set by said first count setting means;
• and
• first resetting means for resetting said defect items and said defect item count written to said detected testing means failure file when the testing of said product by said same automatic testing means proves said product to be good.
