Abstract [en]

Making sterilization machines for hospitals requires much testing. The testing takes place at the producing company. The testing takes a lot of time, and the machines consume a lot of electricity, water, and compressed air. In case of software failure, all the tests must be done again. Accordingly, there is a need for more environmental and economy-friendly testing. The Hardware-in-the-loop (HiL) is a powerful test technique that can efficiently test embedded control systems. Embedded systems and HiLs are most common in the automotive industry. This research aims to create an environment, functioning as a workbench, in which controller-like hardware will operate. (The environment will use the PCI eXtensions for Instrumentation (PXI) model and software comprising Measurement & Automation Explorer Help for PXI (MAX), LabVIEW, and VeriStand). The environment will simulate different sensors and signals so that the controller can be tested rapidly under a testing protocol before taking it to an actual machine. This thesis describes how a HiL simulation system was developed to make a much more environmentally and economy-friendly testing based on software without having a running machine that consumes much energy and water. 

Abstract [sv]

Att tillverka steriliseringsmaskiner för sjukhus kräver mycket testning. Testningen sker på det producerande företaget. Testet tar mycket tid och maskinerna förbrukar mycket el, vatten och tryckluft. I händelse av mjukvarufel måste alla tester göras igen. Det finns därför ett behov av mer miljö- och ekonomivänliga tester. Hardware-in-the-loop (HiL) är en kraftfull testteknik som kan användas för att effektivt testa inbyggda styrsystem. Inbyggda system och HiLs är vanligast inom fordonsindustrin. Målet med denna forskning är att skapa en miljö, som fungerar som en arbetsbänk, där styrenhetsliknande hårdvara kommer att fungera. (Miljön kommer att använda PCI-extensions for Instrumentation (PXI)-modellen och programvara som omfattar Measurement & Automation Explorer Help för PXI (MAX), LabVIEW och VeriStand). Miljön kommer att simulera olika sensorer och signaler så att styrenheten kan testas snabbt enligt ett testprotokoll innan den tas till en verklig maskin. Den här rapporten  beskriver hur ett HiL-simuleringssystem utvecklades för att göra en mycket mer miljö- och ekonomivänlig testning baserad på mjukvara utan att ha en maskin i gång som förbrukar mycket energi och vatten.
