RFID Chip running marathon

1. Application of RFID Chips in Marathon Races

RFID technology is extensively utilized in live sports events, notably in marathon races. Instead of using a gun signal to start (gun time), large and small-scale marathon events now employ RFID chips (chip time). Athletes are issued with high-frequency UHF RFID tags. RFID readers are placed at starting lines, finish lines, or various checkpoints to track athletes. These readers connect to a control system to accurately record each athlete’s race completion time. Additionally, they integrate with Flycam systems to capture photos of each participant. The evaluation of completion times (chip time) is entirely automated, ensuring absolute fairness in the race.

2. Which RFID Solution is Used for Timing Races?

Ultra-high-frequency (UHF) RFID technology is predominantly used for race timing solutions. UHF can detect over 1,000 tags per second from distances of 10-15 meters from the RFID reader. This makes it an ideal solution for wide and densely packed starting and finish lines in marathon races.

3. Essential Components of RFID Technology for Timing Marathon Races:

The main components of RFID technology for timing marathon races include: RFID tags, UHF RFID readers, and an Arduino Uno microcontroller.

RFID tags: These tags are worn or attached by runners and contain programmed data related to each runner. The tags have integrated antennas that allow them to communicate with RFID readers. They are placed at the starting line and finish line, or can also be positioned at other crucial points along the race course. Typically, the tag attached to the runner’s bib is called a BIB number.

UHF RFID reader: It is a device that operates in the ultra-high frequency range, typically from 840 MHz to 960 MHz. It allows a single reader to simultaneously scan multiple RFID tags within an instant range of up to 5 meters. The UHF reader can read up to 250 tags per second. It is used to track the chip time of all corresponding participants in a marathon race. The reader is waterproof, suitable for use in marathons under various weather conditions.

Arduino Uno: is the interface between the UHF RFID card reader and the computer. The Timestamp feature in the serial monitor of the Arduino Uno is used for capture. Then calculate the chip times of all participants in the marathon.

It can be seen that the application of RFID technology for marathon running brings a very fair solution to runners. At the same time, it helps organizers and referees easily manage the crowd. In addition, RFID technology is also applied in many other sports. It provides fair results and easy management. It can be said that applying RFID technology in sports is a solution for the present and the future.
