Tiivistelmä
This research examines use of automation controllers for the solution of automation problem. The automated car track at the HAMK automation la-boratory was used as an example for implementation. The commissioner of the thesis was the Department of Automation, HAMK University of Applied Sciences. It is located in Häme region in southern Finland having 7 campuses in different locations.
The objective of the study was to build a PLC program that could control the speed of the car. The other objective was to build a HMI so that the process happening at PLC could be monitored from control panel. The control panel is used for reading or writing variables in PLC. This way we could control the whole system from the control panel. In order to implement the task, the knowledge of STEP 7 program and technology objects and function within the S7 CPU was required. Interface programming skills was also essential in order to design the control panel. Understanding of working principle of amplifiers, transformers, proximity sensors, resistors was also needed.
First approach was made to understand the commissioner’s problem. And Then the information (manual, data sheet, and working principle for example) about the components being used was gathered. The technical information was gathered accessing online webpages of manufacturers. Written description of the solution, the SA model was for designing contest diagram and first level data flow diagram. After written description of the system, STEP 7 programming was done. The HMI programming was done using WinCC Flexible and then was integrated with the STEP 7 project.
The car track was controlled automatically. The process could be con-trolled from the control panel and monitor the variables form it. The approach to measure the speed of car at every segment of the car track was done. The speed measurement function was partially successful. Other functions like time measurement and counting the number of laps completed by both cars was also done. The benefits to the commissioning organization were that it received a working car track control system. The main benefits to the researcher were researcher understood overall automation concept design and implementations, design of human machine interfaces.
