Abstract

U ovom radu razvijen je uređaj koji omogućuje automatizirano testiranje višežilnih kabela. Kabeli se spajaju na dva konektora, po jedan kraj kabela na svaki konektor. Ovisno o tipu kabela koji je opisan u digitalnom obliku, mikrokontroler upravlja sekvencom generiranja pobude na jednom konektoru i promatra odziv s drugog konektora. Dovode se ispitni podražaji i čitaju očekivani odzivi na temelju kojih se mogu detektirati prekidi i nedozvoljeni kratki spojevi. U slučaju da je cijela sekvenca testiranja prošla ispravno, upalit će se signalna LED dioda i o tome obavijestiti korisnik, a ako nije, upalit će se druga LED dioda kako bi korisnik znao da nešto nije u redu. Uređaj je povezan s računalom s kojeg se šalje ispitna konfiguracija, a uređaj vraća rezultate ispitivanja te se oni ispisuju na zaslonu računala.

Abstract (english)

In this thesis an electronic device for automated testing of multicore cables was developed. The cable under test is connected to the test device via two connectors, each end of the cable to one connector. Depending on the cable type described in a digital form, the microcontroller generates a test stimuli sequence on one connector and monitors the response of the cable on the other connector. Test stimuli are applied to each pin of the cable and based on the expected responses read on the other end the system can detect broken wires or unexpected short circuits within the cable. In case that the entire test sequence is successful, LED indicator will inform the user that everything is fine, otherwise the other LED indicator will indicate a faulty cable. Device is connected to a personal computer which sends the testing configuration to the device, while the device returns the testing results for informing the user about the status of cable testing.
