Design of Electrical Test Device for Automotive Industry

Abstract

In this study, a test device has been developed that can be used to test various vehicle cables and cable harnesses in the au tomotive sector. The test device can make basic measurements such as conductivity, short circuit, voltage, resistance, capacity, and specific measurements such as diodes and active relays among the number of test points varying between 128-1024. It performs the programmed tests step by step by processing the Test Source Code (*.tkk) files prepared with the designed Interface Program, loaded from the SD memory card in the device. The tester system consists of a selection of test source codes to be run and a general-purpose USB barcode reader, a general-purpose barcode printer, external LED units, an Optional External Unit (OHB) that offer a larger screen and various features if desired, and monitor. The OHB unit can be a Raspberry PI based mini-computer that can be mounted inside or outside the device, or any Windows based computer or Industrial computer can be used if desired. The test device realized has been operated stably with all its functions and has been successfully tested.
