RFID in marathon running

1. How to apply RFID Technology in marathons?

RFID technology is being used for live sporting events. A typical example is the marathon. Instead of using gun command to start (gun time). Now, marathon events on large and small scales all use RFID Technology (time chip). Athletes will be issued a UHF ultra-high frequency RFID card. RFID readers are mounted at the starting line, finish line or some important points to track athletes. These readers connect to the microcontroller system to accurately calculate the athlete’s race completion time. At the same time, connect to the Flycam system to take photos of each athlete. Chip time evaluation is completed automatically. Ensure absolute fairness of the race.

2. What type of RFID solution will be used to time the race?

Ultra-high frequency (UHF) RFID technology is most widely adopted for race timing solutions. UHF can detect more than 1,000 tags per second, from a distance of 10-15 meters from the RFID reader. The ideal solution for wide, crowded start and finish lines in a marathon.

3. Essential components of marathon timing RFID Technology:

Main components of marathon timing RFID Technology include: RFID tag, UHF RFID reader and microprocessor Arduino Uno.

    • RFID Tags: Tags worn or attached by runners include programmed data related to each runner. The tag has an integrated antenna that allows connection to an RFID reader. They are placed at the start and finish lines. Or it can also be placed at other important locations along the race route. Usually the tag attached to the athlete’s bib is called BIB number.

  • UHF RFID reader: is a gadget that uses an ultra-high frequency range, between 840 MHz and 960 MHz. It allows a single reader to simultaneously scan multiple RFID tags  with an instantaneous range of up to 5 meters, and the UHF reader can read up to 250 tags per second. It is used to track the chiptime of all the respective participants in the marathon. The reader is waterproof for marathon races with different 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 marathon participants.

It can be seen thatthe 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 used in many other sports. It provides fair results and easy management. It can be said that the application of RFID technology in sports is the solution for the present and the future.
