Development of a Cable Test Management System (CTMS) Application

摘要

The Test & Trials Department at HII-Ingalls Shipbuilding is responsible for testing specified electrical cablesrninstalled on ships under construction at Ingalls Shipbuilding. These tests are conducted on ships which can have tensrnof thousands of cables pulled, thus HII-Ingalls Shipbuilding personnel must manage a large amount of cable businessrndata. The various tests are performed by skilled Test Conductors using a largely manual, paper-based process torngather and manage the test data. Test & Trials Department personnel maintain these datasets and associate specificrnTest Procedures to ship equipment operating requirements by cable or circuit type. CTMS required developing twowayrncommunications: 1) Between the CN3 mobile device and a windows computer with an Access databaserncontaining specific cable information and used as a repository for the actual test results and 2) Between the CN3rnmobile device and the test equipment to pass specific test criteria to the test equipment and the test conductor and torncapture the actual results. Custom device drivers were written to allow direct serial communication between thernIntermec CN3 handheld computer and the Anritsu Site Master™ S820D Analyzer. This setup allowed the team tornmeet the goals of the project; leveraging existing devices to improve data reliability and expose new potential forrnprocess improvement in the cable test environment.
