Automated measurement setup
Qiu Yin · 2014
Within NXP Semiconductors the Business Line Power and Lighting Solutions (BL PLS) is active in the area of mains AC/DC converters for power supplies (e.g. GreenChip adapter family) and Lighting applications (e.g. drivers for Compact Fluorescent Lamps and Solid State Lighting) The measurement setup designed in this report can help the engineer to test the parameter of dimmer compatibility convenient. The measurement setup includes hardware part and software part. Through the hardware setup, the dimmer can be controlled by software and the parameter can be measured and the result of the measurement can be exported automatically. The results of this research project is divided into four parts according to the Delft Design Method. In analyze phase, the focus is on the relevant research fields. After this phase, the dimming principle and the requirements for the setup is clear. In concept phase, the focus is on the function tree of the setup and selection the concept for every function. And combine the concept for every function together. In materialization phase, the schematic circuit of the best concept is clear. The prototype for both hardware part and software part were made. In the detailing phase, the test of the prototype was done and the circuit board was installed into box. Also the user manual is written. At the end of this project, the development of the automated test setup was not finished completely. The test result need to be handled with software, it is not accurate. Also the detect point is not isolated, which may cause the equipment damage. The hardware needs to be improved to make the setup more accurate and more safety. More details will be discussed in the main part of the report.
