Implementation of harness testing device using microcontroller

The paper describes the developed microcontroller device for testing and controlling the production of cable harnesses in the automotive industry. Based on the results of the testing, a decision is made as to how and whether the work process can continue through logical management of the implemented mechanisms in the system. The device has been implemented in production at the plant of the Hronovski company in the town of Smolyan. The cable harnesses are used in the production of automotive lighting systems, such as taillights, front lights, daytime running lights and auxiliary lights. The tester is suitable for use in engineering education and training of industry professionals. It is used to teach microcontrollers, programming, and testing and diagnostics in the mass production at Plovdiv University “Paisii Hilendarski” - Faculty of Physics and Technology. Modern production requires high expert potential from those working in it, direct interaction between universities and industry, and this is done with the use of modern effective environments, methods and tools.
