Styrutrustning för gnistprovningsapparat / Control equipment for Spark ignition testArabäck, Niklas, Sturesson, Klas January 2008 (has links)
Denna rapport beskriver utvecklingen av en ny styrutrustning för SP´s provning av elektriskaprodukter som sitter i explosionskänslig miljö. Enligt svensk lagstiftning måste produkternauppfylla ATEX-direktivet. SP har en gnistprovningsapparat för provning av elektriskaprodukter. Styrutrustningen till gnistprovningsapparaten har genom åren blivit omodern ochbesvärlig att använda. Den gamla utrustningen är konstruerad på tidigt 80-tal och saknar enkomplett dokumentation. Den bristfälliga dokumentation och komponenter som idag inte gåratt få tag på har gjort utrustningen osäker. Önskemålet är att konstruera en ny styrutrustningsom går att styra med mjukvara utvecklad i LabVIEW 6.1.Ny hårdvara har konstruerats med inventarienummer 504140. Utrustningen har blivit merkompakt och enklare för operatören att använda. En komplett dokumentation har tagits framför den nya styrutrustningen. Hårdvaran kontrolleras nu via ett USB gränssnitt till dator.Mjukvaran som används är utvecklad i LabVIEW 6.1 med namnet Spark Ignition Test v2.0. / Uppsatsnivå: C

Application of Lab VIEW in Smart Home Surveillance SystemsChen, Kun-Wei 23 June 2011 (has links)
The objective of this research is to study smart home network systems and the application of Lab VIEW to develop man machine interface (MMI) so that traditional instrument panels can be replaced with virtual panels to reduce the consumption of hardware resources. For energy efficiency, the focus is on using MATLAB¡¦s fuzzy toolbox as the computing center and applying it to both lighting and air-conditioning systems. This thesis also looks into the use of Lab VIEW¡¦s CGI tools to develop remote monitoring functions as well as embedding the network related syntax into the Web pages. The user not only can use his/her computer equipment, but also their mobile devices (cell phone, PDA, pad, etc.) to link up to the networks and conduct remote monitoring, which enhances convenience and security.
Hardware using wired control (PCI, Ethernet) and wireless control (ZigBee) could monitor the information from the components and transmit it to the computer for processing using the aforementioned method, and finally send it to the control end to complete the monitoring process. Choosing ZigBee wireless control is because it is more energy saving and network friendly than other wireless devices.It will have were opportunities to be used in home applications in the future.
This thesis also integrates a fuzzy control for the power consumption. Test results show that adding fuzzy control can reduce power consumption. Besides using computers for remote monitoring functions, cell phones and pads were used as well.

Chemically Programmed Memory Card and PC Connected Memory Card ReaderVadakke Kunninmel, Gokuldev January 2013 (has links)
Inkjet-printed memory cards have been developed previously by re-searchers at Mid Sweden University but, these did possess some limita-tions, as each resistive memory cell required one physical contact and the resistances were designed to be electrically programmed.This work overcomes the above limitations by developing chemically programmed printed memory cards and a PC connected memory card reader. Printed memory cards are inexpensive and are developed by inkjet printing the nano-silver ink onto the photo paper substrate. A matrix readout method is used to increase the num-ber of memory cells and, by using a chemical solvent, the resistances were programmed to the desired resistance values and, for which, each resistance value represents data on the cards, called, write once read many (WORM) memories. The memory card reader was developed to access the data (resistance value) of the memory card and also to trans-mit the data to a LabVIEW graphical user interface for displaying the resistance values. By using multiple resistance steps, in which each step represents a different state, it is possible to create a number of possible selectable combinations which can be programmed at a later stage for developing applications.

Design and construction of modular event detector system / Design och konstruktion av modulärt händelsedetektorsystemEricsson, Jenny January 2003 (has links)
<p>This thesis describes the function and construction of a modular event detector system. Event detectors are used for solder joint reliability testing using electronic monitoring for short duration resistance changes during accelerated ageing and temperature cycling. Collected data is mainly used to study solder joints long-term properties. The system has three different monitoring functions: transient resistance detection, statistics process monitoring and periodic monitoring. In its present performance a total number of 384 channels can be monitored continuously. However the system can be expanded in steps of 96 channels, limited only by the capacity of the computers PCI-bus. The system is built around a PC equipped with the LabVIEW 6.1 programming environment and data acquisition cards from National Instruments. The circuit boards to be monitored are connected via adapter electronics. In the case of the superior electronic-kits project, four groups of 24 circuit boards are connected to the adapter electronics. To minimise the influence of environmental noise shielded and, where possible, twined cables are used.</p>

Measurement of Fe (II) in Waters using Flow Injection Analysis (Gulf of Bothnia, Sweden)Bartel, Claire January 2013 (has links)
A new Ph.D research project was started early October into the Department of Civil, Environmental and Natural Resources Engineering at Luleå University of Technology (LTU) by Sarah CONRAD under the direction of Johan INGRI. The part of this project in which I participed was the determination of the concentration of Fe (II) by flow injection analysis using chemiluminescence in the Bothnia Bay. The missions were to handle the instrument and the software and to prepare also some sample standards for the calibration of the FIA. The stream water is first sampled and filtered. Then the water, containing either just the natural iron in the water or after addition of artificial iron, is analyzed by flow injection analysis in combination with luminol. The results are saved on the laptop and interpreted later. The experiments were performed on both the field and the laboratory of the University. / <p>Validerat; 20131008 (global_studentproject_submitter)</p>

The Diploma thesis deals with the testing of electrically assisted turbochargers. Aim of this work is to apply the established way of the performance testing of conventional turbochargers for electrically assisted turbocharger. Part of this work is to create a program for the calculation of the observed characteristics of the turbocharger. The program is extended to the characteristics of the generator for electrically assisted turbocharger. The program will serve as a basic for control the data for tested motorsport applications.
