Active, sensor-based UHF-RFID-System for a complete monitoring and traceability of the cold chain

摘要

Aim of the presented work is the development of an active monitoring system for the cold chain traceability. With the sensor-based Radio Frequency Identification (RFID), data, especially temperature are detected in a truck environment and the measurement results are transmitted to a central database. As novel sensor-based transponder, a semi-passive and an active solution is presented. For this application, platinum temperature sensors with highest resistance (Pt10.000) and smallest dimensions (2 mm x 2 mm) are used. The deciding advantage for this system is that in case of an exceeding of defined temperature limits, the system triggers an alarm and allows various mechanisms to avoid the spoilage of perishable goods.
