RFID runway timing technology application

 

Abstract:?With the advancement of modern science and technology, track and field competitions have introduced a large number of advanced technologies, and the application of electronic timing equipment in track and field competitions has become more and more obvious.?In large-scale sports games, the timing system used is a high-definition strobe camera timing system, which is complicated and expensive to operate, and is not affordable to all organizers or organizations.?In some small and medium-sized sports games, the timing methods used are manual manual timekeeping, and the errors are large, which restricts the development of mass sports.?RFID runway timing technology races against time!

With the advancement of modern science and technology, track and field competitions have introduced a large number of advanced technologies, and the application of electronic timing equipment in track and field competitions has become more and more obvious.?In large-scale sports games, the timing system used is a high-definition strobe camera timing system, which is complicated and expensive to operate, and is not affordable to all organizers or organizations.?In some small and medium-sized sports games, the timing methods used are manual manual timekeeping, and the errors are large, which restricts the development of mass sports.?RFID runway timing technology races against time!

  In the physical training assessment, it is necessary to record the exercise time and successive rankings of the assessors from the starting point to the end point. Generally, the old and classic method is the manual stopwatch timing.?With the development of technology, RFID chronograph circles have emerged.?Cooperate with the assessment system for the timing of physical training.

  The professional sports chip timing system has unparalleled superiority for the number of athletes, the complex competition environment and the high competition results.

  The use of the chip timing system not only saves a lot of manpower for the organizer, but also provides the most accurate report and the most valuable data analysis in a short time.

  When the sports timing chip carried by the athlete passes the timing carpet, the carpet antenna transmits the response signal of the received motion timing chip to the read head connected thereto, and the read head records the current time and the related information of the chip, that is, the timing function is completed.

  The results of the game can be displayed in real time, and the referee or training organizer can view, edit, and print the results through the sports timing system software installed on the computer.

Accurately recording the number of laps traveled by each assessor has always been a major problem: for many years, the referee has recorded in the form of artificially playing chessboards and manually drawing forms. In addition to the large amount of manpower and material resources, human error is inevitable. Affect the accuracy of the results.?In order to accurately interpret the rankings and achievements of the assessors, ensure that the results are open, fair and just.?Combining with the high-tech of today's radio frequency identification, we have developed a professional sports automatic chronograph circle system suitable for medium and long distance competitions.

  The system consists of three important hardware products and timing management software consisting of electronic timing transmission system, electronic intelligent timing system, and evaluation personnel timing chip label.

  a) Starting point: consists of an electronic transmission system, including a wireless electronic firing gun, equipped with a speaker amplifier, and an electronic transmission host device

  b) Monitoring point: by RFID electronic timing host device, carpet sensing antenna (can have multiple monitoring points or no monitoring points)

  c) End point: composed of RFID electronic timing master device, carpet sensing antenna, wireless router, running time management software computer

  Realization principle: The system adopts advanced RFID technology, computer information processing and other high-tech and physical training assessment, which is convenient for the assessment personnel to carry without affecting its state. When the assessment personnel bring the RFID timing chip label through the carpet induction antenna, read and write. The antenna can immediately detect the passed card information, and the reader sends the read card number to the connected computer. The computer obtains relevant information of the assessor and uses a special software to process the information.?The collected card information is corresponding to the corresponding athlete information by the system software, and the game situation is counted, thereby realizing the purpose of automatic counting and automatic timing of long distance items.

  First, the wireless electronic dispatching system controls the loudspeaker to issue a starting command, and at the same time, the electronic timing master device synchronously receives the start command and starts timing.?Secondly, after the assessment personnel pass the monitoring point and then pass through the end point, the RFID electronic timing master device senses and counts the circle.?Finally, when the appraisers finish the assessment and run through the finish line, the system counts the final score and saves the history.

  By changing the position of the starting point, monitoring point and end point, it is possible to adapt to the situation of long distance running chronographs in different distances.

  Radio Frequency Identification (RFID), also known as Radio Frequency Identification (RFID), is a communication technology that identifies specific targets and reads and writes related data through radio signals without the need to identify mechanical or optical contact between the system and a specific target. .?RFID technology is used in track and field competitions. It has the characteristics of quick response, accurate timing and convenient use. It is low in cost and easy to promote.?The RFID track and field timing system is composed of a starter gun wireless signal transmitter, an end point RFID identification device, an RFID tag, a terminal information processing computer, an athlete database, and an information processing system.?System work overview: The check-in office records the athlete information into the terminal database and writes the RFID tag; the starting point gun signal transmitting subsystem transmits the game start signal to the terminal; the RFID reader at the end reads the RFID tag on the athlete, and the signal Transfer to the terminal, record the athlete's competition results, and enter the information processing system database to complete the track and field competition timing work.
