Abstract [sv]

Detta examensarbete utfördes som ett uppdrag av Atlas Copco där målet var att utveckla en

programvara som kan simulera en OU (Operator Unit) i en PC miljö. Atlas Copcos

egenutvecklade radiostyrningssystem för gruvfordon består av en sändare, kallad OU, och en

mottagare, kallad MU (Machine Unit). En OU är en kontroller med reglage i form av knappar,

joysticks och switchar och med indikatorer i form av LEDs och display. För att säkerställa att

en OU endast kan kommunicera med en specifik MU och vice versa måste enheternas

radiomoduler paras ihop genom en process som kallas ”learn link”, som görs genom att

ansluta en CAN-kabel mellan enheterna.

 

Genom att använda en OU simulator vid MU produktionstest skulle det vara lättare att utföra

vissa tester, såsom internfel och varningar, och det skulle vara möjligt att inkludera tester som

är omöjliga att göra med en hårdvaru-OU, som att avsiktligt sända en felberäknad

checksumma, för att undersöka MU-enhetens respons. OU simulatorn skulle ha ett grafiskt

gränssnitt och genom att ansluta ett radiokort till PC:n skulle den kunna skicka och ta emot

data från en MU. Den skulle också kunna utföra ”learn link”. Den färdiga produkten

utvecklades med hjälp av C# och en XP-inspirerad utvecklingsmetod.

Abstract [en]

This thesis was developed as an assignment from Atlas Copco where the goal was to develop

software that could simulate an OU (Operator Unit) in a PC environment. Atlas Copco’s

proprietary radio-control system for mining vehicles consists of a transmitter, called OU, and

a receiver, called MU (Machine Unit). An OU is a controller with controls in the form of

buttons, joysticks and switches and with indicators in the form of LEDs and display. To

ensure that an OU only can communicate with a specific MU and vice versa the units’ radio

modules must be paired together through a process called “learn link”, that is performed by

connecting the units with a CAN-cable.

 

By using an OU simulator for MU production tests it would be easier to perform some tests,

such as internal errors and warnings, and it would be possible to include tests that are

impossible to do with OU hardware, such as intentionally send a miscalculated checksum, to

examine the MU’s response. The OU simulator should have a graphical user interface and by

connecting a radio card to the PC it should be able to send and receive data from an MU. It

should also be able to perform “learn link”. The final product was developed using C#

together with an XP-inspired development method.
