Undersökning och framtagning av ett moduluppbyggt datainsamlingssystem

Sammanfattning: This report is about a thesis that is performed in and for SYSteam Engineering AB in Motala. The thesis work is divided into three parts, study of the market, programming and electronics. The study part consists of examining and comparing different data acquisition systems for testing of different circuit boards, taking into account the modularity, real-time applications, mobility, environmental, interface hardware and software, to be able to define a general module-based data acquisition system in both hardware and software that enables for future developments. The programming part consists of getting started with Visual Studio, which integrates the Measurement Studio for C#. NET. Measurement Studio includes classes and user controls for testing and measuring and offers tools for acquisition, analysis and presentation of real world data. The programming has been the biggest part of the project, the orienting of test specification and to learn how to program and control the hardware according to the test conditions took the most of time. Electronics is the part that took the least time, which consists of orienting the test specification, connecting cables to the I/O modules and supplements the system with any components which is necessary to execute the various test cases. The result was a system consisting of a chassis with a number of modules that National Instruments offers and a test program consisting of three class levels that can be reused in different projects and for different test items.
