Shipboard Control System
Customer Need
Sailors aboard nuclear-powered submarines and ships require the ability to fully test electronic assemblies prior to installing in an operating system. AVID was requested to develop fully automated portable testers that duplicate the factory acceptance testing of 10s of different electronic assemblies. These testers need to be rugged for shipboard uses as well as take up as little physical space as possible.
AVID's Solution
AVID developed a chassis system which included self-storing characterization boards for each unique board to be tested. Various PC programmable test and measurement equipment was used to simulate inputs and monitor outputs. A master test executive PC application program was developed to run the tests and included step by step instructions, pictures, and test logging. The specific test sequence and acceptance criteria are defined by an Excel spreadsheet which allows non-programmers to easily modify the steps or parameters. A final compile function allows the Excel sequence and limits to be built into a single run-time executable to prevent unauthorized changes.
