To increase Measuring Accuracy in the System HiMacs (English)
Abstract [en]

The industry is now entirely dependent on computer systems in various parts of the

organization. As systems become more powerful the opportunities for increased control and

precision grows. The more defects and faults that can be detected before delivery, more

customer satisfaction is obtained which leads to fewer unnecessary costs connected to, for

example, recalls. Of course, this is desirable from the industry and leads to higher demands

for information systems.

 

This report discusses the opportunities to increase the measuring frequency of an existing

industrial realtime system running on a PC with Windows as operating system that is

designed for test runs and measurements of engines and transmissions. Limitations that

comes with using a nonreal time operating system in a real time industrial application is

cleared up. The option for real time communication that HiMacs uses, developed by

Beckhoff Automation, is also described.

 

The project was investigative and various proposed solutions were developed and compared

to each other to achieve the most reliable solution.

Abstract [sv]

Industrin är idag helt beroende av datasystem till olika delar av verksamheten. I takt med att

systemen blir kraftfullare växer möjligheterna för ökad kontroll och precision. Ju fler defekter

och fel som kan upptäckas innan leverans desto nöjdare kunder fås och medför färre onödiga

kostnader vid exempelvis återkallelser. Givetvis är detta önskvärt från industrins sida och

leder till att kraven på datasystemen blir ständigt högre.

 

Denna rapport avhandlar möjligheterna att höja mätfrekvensen för ett befintligt industriellt

realtidssystem som körs på en PC med Windows som operativsystem och är avsett för

testkörning och mätning av motorer och transmissioner. Begränsningarna som medföljer då

ett ickerealtidsoperativsystem används reds ut och det alternativ som HiMacs använder

utvecklat av Beckhoff Automation beskrivs.

 

Projektet var utredande och olika lösningsförslag togs fram och vägdes mot varandra för att

komma fram till den mest pålitliga lösningen.
