Lights Go On, Lights Go Off

摘要

Hella needed to produce two automated testers capable of R&D testing, design validation and product validation for automotive signal light flasher modules. It also wanted to use common software on both testers to reduce cost. The solution was to use the rapid application development power of LabVIEW along with National Instruments' (NI) signal conditioning and data acquisition equipment to make a 6-unit and a 15-unit tester. Hella produces electronic modules and systems for the automotive industry. In order to respond quickly to new designs, the Product Development and Engineering Laboratory has standardised on LabVIEW software, PCI-MIO data acquisition boards, and SCXI signal conditioning. This paper examines the system and software design techniques used on a pair of flasher module test systems. Fully automated testers were created to meet the specifications of the automotive OEM. One tester is dedicated to endurance testing, while the other tester performs parametric and short-term tests.
