DESIGN OF AN RFID â€œ BASED MANUFACTURING MONITORING AND ANALYSIS SYSTEM
Radio Frequency identification technology has become an important driver in the modern production logistics activities of todayâ„¢s information-based industries and economics. With the modern development and latest technology, companies focus more on how these technologies can be implemented and promoted in order to improve their value-added process.
In this project presents one such practical implementation approach for the monitoring and analysis of a discrete manufacturing environment using the super RFID technology. Monitoring the parts flows in manufacturing system time-wise and location-wise is very critical for productivity, cost, quality, inventory, and speed. In companies when the production automation has been implemented the parts are monitored by the system. This may allow better monitoring of the manufacturing process with expedient material flow and more effective planning and control.
This super RFID based manufacturing monitoring and analysis system to monitor where and when a part is located throughout its flow in a production process using RFID tag placed on the parts and antennas located at appropriate places. The system will enable the visibility of multiple parts simultaneously without requiring operator support and collect the following information related to a part.
1. Arrival time to a workstation.
2. Activity starts time.
3. Activity end time.
4. Departure time from the workstation.
5. Location of a part.
In this system every parts in the production is equipped with a super RFID tag. The manufacturing plant is installed with reader antenna at appropriate locations. The data from the part/tag is read on real time. The reader can receive data from many tags at a time. The location information and other data is processed in the base reader unit and feed in to a PC. The final display is shown in the PC using software.
Hardware involved. : Super compact active RFID tag (as per monitoring parts required) Directional antenna, Reader base unit, Interface adaptor, PC software.
