1. Project background introduction
In the physical training assessment, it is necessary to record the exercise time and ranking of the examiner from the starting point to the end point. Generally, the ancient and classic method is to manually count the time with a stopwatch. With the development of technology, RFID timing laps appeared. With the assessment system, it is used to count laps for physical training.
It has always been a big problem to accurately record the number of laps traveled by each examiner: for many years, referees have been recording by means of manual chessboarding and manual drawing of forms. In addition to consuming a lot of manpower and material resources, human error is inevitable. Affect the accuracy of grades. In order to accurately judge the ranking and results of the examiners, to ensure the openness, fairness and justice of the results. We have combined the high technology of today’s radio frequency identification to develop an automatic lap counting system for sports clubs suitable for middle and long distance competitions.
2. System composition and realization principle
System composition: The system is composed of a sensor bracelet for assessors, three deployment points of the system, and three major parts of the system software.
As shown in the figure, the hardware composition of the three deployment points of the system
a) Starting point: Composed of wireless remote control switch and loudspeaker
b) Monitoring point: composed of RFID reader, antenna and wireless router (there may be multiple monitoring points or no monitoring points)
c) End point: consists of RFID reader, carpet antenna, wireless remote control switch signal receiver, wireless router, and computer running software
Realization principle: The system adopts advanced RFID technology, computer information processing and other high-tech combined with physical training assessment, which is convenient for assessors to carry without affecting their status. When assessors carry radio frequency identification cards (RFID tags) through the carpet antenna, The reader antenna can immediately detect the card information passed, and the reader sends the read card number to the connected computer. The computer obtains the relevant information of the examiner and uses special software to process the information. The system software corresponds the collected card information with the corresponding athlete information, and counts the competition situation, so as to realize the purpose of automatic lap counting and automatic timing of long-distance events.
First of all, the wireless remote control switch controls the loudspeaker and sends out the start command. At the same time, the end receiver synchronously receives the start command and starts timing. Secondly, the examiner passes through the end point after entering the monitoring point, and the RFID reader recognizes and counts the laps. Finally, when the assessor finishes the assessment and runs past the finish line, the system will count the final score and save the historical record.
By changing the positions of the starting point, the monitoring point and the end point, it can adapt to the lap counting situation of the middle and long distance running at different distances.
3. System hardware
(1) RFID reader
RFID four-channel fixed reader, brand: SWIFTEK, model: SW-R4. SW-R4 is a high-performance UHF four-port fixed RFID reading and writing device, supporting ISO18000-6C/6B two protocols, working frequency band supports national standard dual frequency 920MHz～925MHz, 840MHz～845MHz and FCC, 902MHz～928MHz and ETSI, 865MHz～868MHz, output power 0～33 dBm.
(2) 5dBi UHF RFID carpet antenna is used for sports timing, brand: SWIFTEK, SW-FL01: carpet antenna can be conveniently used in retail industry, conference management, personnel management, RFID sports timing, road pine events and other UHF frequency bands RFID occasions.
(3) UHF antenna-9dBi cross-line polarization IP67 Brand: SWIFTEK, Model: SW2
SW2 is a high-end 9dbi cross-polarized antenna, which can be conveniently used in UHF frequency band RFID occasions such as access control, warehousing, logistics, and retail
(4) UHF personnel wristband electronic tag or shoelace tag
The electronic tag solves the weakness of the previous UHF electronic tag performance affected by the human body, and realizes stable long-distance recognition in the human wearing environment. At the same time, the appearance is specially designed to be durable and comfortable to wear. The protection level is IP67.
