\u2022 RFID (13.56 MHz):<\/strong> Self-adhesive, low-cost tags and relatively economical readers.<\/p>\n\n\n\n RFID in the 13.56 MHz frequency range was particularly appealing: Each measurement point could be uniquely identified by an RFID tag without the need for a line of sight. Nevertheless, some questions remained: Is the read range sufficient at a travel speed of 2.5 m\/s? How reliably will the tags be detected if they are within range of the reader for only fractions of a second?<\/p>\n\n\n\n To test whether 13.56 MHz RFID would meet these requirements, our experts first built an Arduino-based prototype: an RFID reader, a few tags\u2014and we were ready to go. However, the initial results showed that stable detection at a speed of 2.5 m\/s was not always guaranteed:<\/p>\n\n\n\n \u2022 At a maximum range of 5 cm, the tag is within reading range for just 0.04 seconds.<\/p>\n\n\n\n \u2022 During testing, IDs were sometimes recognized only every other time. This behavior is due to the way RFID works. Tags are activated by the reader only when they come within range. As soon as a tag is activated, it transmits its ID and enters a READY state, during which it does not retransmit its ID. Only when the tag is moved out of the reader\u2019s range (or when actively interacted with) does it retransmit its ID upon activation.<\/p>\n\n\n\n (Image: RFID for location tracking)<\/p>\n\n\n\n A rotating test setup was used to simulate the vehicle passing by under realistic conditions. This allowed the tag to be repeatedly removed from and reinserted into the detection range, thereby circumventing the READY issue. The tests revealed:<\/p>\n\n\n\n \u2022 Maximum speed:<\/strong> Under ideal conditions, the system still functioned at 2.9 m\/s.<\/p>\n\n\n\n \u2022 Improved detection:<\/strong> The rotation caused the tags to be brought into the reading range briefly on multiple occasions, which improved the recognition rate. However, the short range remained a problem.<\/p>\n\n\n\n The tests revealed two main problems:<\/p>\n\n\n\n 1. Reliability:<\/strong> During the simulated pass-by, there was often not enough time to safely activate the tag and reliably read the ID.<\/p>\n\n\n\n 2. Range:<\/strong> A reading range of just a few centimeters meant that placing the tags would be too labor-intensive and the margin for error would be too small.<\/p>\n\n\n\n Consequently, it was necessary to consider other RFID options. In follow-up tests, for example, 868-MHz technology was used, which allows for read ranges from 50 cm to 2 m\u2014and the transmission power can also be adjusted flexibly. This not only provides sufficient leeway for fast-moving objects but also accommodates various mounting and environmental conditions.<\/p>\n\n\n\n In addition to position tracking, RFID can also be used for temperature monitoring. There are battery-powered RFID tags designed for this purpose that can independently measure and store temperatures over extended periods of time. While this wasn\u2019t strictly necessary in our project\u2014temperature measurements were taken only as the vehicle passed by to detect a possible rise in temperature (e.g., due to a faulty engine)\u2014this scenario illustrates the potential of RFID:<\/p>\n\n\n\n \u2022 Position tracking and sensor data management can be combined without having to install costly wiring or equip each object with its own wireless module.<\/p>\n\n\n\n This example clearly demonstrates that technical solutions must be effective not only in theory but, above all, in practice. Such an iterative approach\u2014from the initial idea through the proof of concept to the tailored solution\u2014is the key to robust results. The following insights, in particular, have helped us make progress:<\/p>\n\n\n\n \u2022 The first attempt is rarely perfect:<\/strong> Even solutions that seem inexpensive and simple can reach their limits in real-world operation.<\/p>\n\n\n\n \u2022 Practical tests instead of just theory:<\/strong> Only through testing\u2014under realistic conditions\u2014can we determine whether a technology is robust enough.<\/p>\n\n\n\n \u2022 Carefully weigh the costs and benefits:<\/strong> In the IoT environment in particular, it is not only hardware prices that are crucial, but also installation and maintenance costs.<\/p>\n\n\n\n In our projects, we place great emphasis on this iterative approach. This is the only way to select the right technologies and identify potential missteps early on. Ultimately, what matters isn\u2019t having the perfect solution right away, but quickly determining which paths lead to the goal\u2014and which don\u2019t. That is exactly what we mean by expertise: flexible, practical, and cost-effective software and system development.<\/p>","protected":false},"excerpt":{"rendered":" \u00dcber 1.000 Messpunkte, unz\u00e4hlige Sensoren, gro\u00dfe Distanzen \u2013 bei einer Sortieranlage eines Logistikunternehmens in dieser Gr\u00f6\u00dfenordnung wird die \u00dcberwachung schnell zur logistischen Herausforderung.
