ABSTRACT
Finding an effective method for accurate and reliable data collecting during production processes has been a concern of many industrial producers. Mass production in industrial environment involves fulfilling customer requirements and obligatory quality control standards. So gathering data in supply chain generally and especially in production lines is compulsory. In addition to customer requirements, competition and progress in harsh economic environment needs reliable and on time data.
This thesis focuses on the production system of a company named SKC, which collects data based on user reports. Operators must report their productive activity in detail at the end of every process/task or at the end of working day. Numerous reports not only waste the valuable production time of operators, but also increase the risk of mistake and data inconsistency in manual steps of reporting and data entry. Furthermore, data is not available before the next working day which delays dynamic planning and mistake preventing actions.
This thesis provides a design to replace this old-fashioned system with a system that is based on new technologies. Even in this case economical justification is a great motivation for change. The main subject is to automatically identify materials, operators, and machinery equipment for every batch of final products. This online data tracking will make a great control opportunity. To present a systematic and practical design for automated data gathering, a specified type of production has been considered, although the main idea and concept can be used in similar cases. It has been tried to describe the topic in general way, after that, any selection that has been made is based on real conditions in considered company, which is a labor-oriented assembly line.
In the designed solution, any important object including and not limited to operators, batches of final products, raw materials and production machines are equipped with RFID tags. In collecting points like Production Stations a special device reads the tags and by using Wireless Sensor Network (WSN) the data is sent to the Sink, which is connected to the network and the data is inserted to a database. The reader device associated to production station is combined from RFID reader module and ZigBee module. A LCD display and a keypad are added for more functionality.
