The implementation to date includes the development of a system for the simultaneous identification and localisation of any number of objects in production and logistics. This includes the expansion and scaling of magnetic field-based localisation technology for RFID transponders. In addition, a system is being researched that recognises events based on location data, as well as a detailed mapping of material flows and cost efficiency.
Small and medium-sized enterprises (SMEs) in particular often have insufficient digitalisation of their work processes. On the one hand, the problem relates to identification, as the manual recording of goods by employees in incoming and outgoing goods is prone to errors. This can lead to problems such as the reading or omission of identifiers, which has a significant impact on the accuracy of the data. On the other hand, the issue affects localisation, as the time delays in digital process mapping caused by manual scans lead to inefficiencies and increased logistical effort. This makes it more difficult to locate goods precisely, which impairs the efficiency of the entire logistics process. These two aspects highlight the need for better digitalisation in order to optimise both the identification and location of goods.
The identification of KLTs (small load carriers) on the shelf is realized through the use of advanced transponder technology, which enables extremely precise and location-accurate localization. The aim of this technology is to identify various application scenarios and derive specific requirements based on them.
In this project, an innovative system will be developed that is able to distinguish and localize passive LF RFID transponders attached to articles or containers. Communication with these transponders is designed to include both identification and access to the stored data and is based on the standards of common RFID systems.
In the first implementation phase, a laboratory demonstrator was developed that uses specially programmed RFID transponders that use the so-called Gold Codes and work in Transponder Talks First mode. However, only a limited number of transponders are possible in this mode. At the same time, a comprehensive comparative analysis of alternative solutions based on concepts such as "Transponder Talks First", the use of short codes and a combined transponder inventory is being carried out. This analysis also takes into account aspects such as selective communication and precise localization, which means that events such as the removal of containers can be reliably detected.
In addition, concepts will be developed to extend functionality beyond standard RFID functions, including the use of sensors and actuators to provide additional data capture and processing capabilities. Finally, a thorough evaluation of the usability and cost-effectiveness of the systems will be carried out, with a focus on user acceptance of the technologies to ensure that the solutions developed are both practical and appealing to users.
