Microcontroller based industrial automatic timer control system

Within the framework of this dissertation, firstly the counters, timers and programmablerelays that are used in industrial applications have been examined, and subsequently a circuitwhich is parallel in its structure to the circuits examined has been designed. In addition, auser-machine interface that can control this circuit has been designed using the LABVIEWprogram.The system has been realized on two major issues. These are the electronic circuit board onwhich the relays to be programmed are located and the program which enables us to programthis board via computer.In the first chapter, the application fields of the counter/timer and the programmable relays,and the functions they fulfill have been focused.The ATMEGA162 microcontroller that controls the hardware part of the system has beenconstrued in the second chapter.With the aim of providing examples for the system intended to be designed, various types ofcounters/timers and programmable relays which are used in the industrial applications havebeen given in the third chapter. In this way, we will have the opportunity to compare thesystem we have designed with existing products.In the fourth chapter, the details of the hardware of the system which has been designedduring this dissertation have been analysed.In the following chapter, preliminary information pertaining to the LABVIEW program withwhich the user-machine interface of the system was designed has been given and details aboutthe program used within this application have been provided. Additionally the communicationbetween the firmware, the hardware and the user-machine interface has been explained in thischapter.In the last chapter, the system that was designed in this project has been compared to analogsystems which are used in the industrial applications and the results of this comparison havebeen listed.Key Words: Counter, Timer, Programmable Relay, LABVIEW.
