1. System overview
Sports running timing system uses radio frequency identification (RFID) system, 125K low-frequency activation technology, computer information processing and other high-tech combined with sports, which is convenient for athletes to carry without affecting their competitive state. The system has a timing accuracy of up to 10ms, which can fully meet the requirements of modern sports competitions. It can also be used for running statistics and management of multiple character goals. It can be used for the statistics and management of school students’ running competitions or running results, which improves the accuracy of running results and saves manpower and time.
2. System principle
Whenever athletes bring dual frequencyelectronic labelWhen passing the timing coil on the runway, the 125K low-frequency activation antenna can immediately activate the dual-frequency electronic tag information. The dual-frequency electronic tag actively sends data to nearby readers in real time, and the reader uploads the read card data to the connected computer. , The computer obtains the relevant information of the athletes, and records the corresponding time when passing, and uses special software to perform a series of processing on the information. The start time of running can be collected by the “timing start” button drawn by the reader and uploaded to the computer back-end system software. The back-end system software corresponds the collected start time and card information with the corresponding athlete information, and counts the competition situation, so as to realize the running status. The purpose of automatic project timing.
The system can lay a set of ground-sensing coils at the finish line for game timing, and it can also set up multiple ground-sensing coils on the runway for real-time monitoring of athletes’ competition conditions.
Three, the main function of the system
1. Statistics of athletes’ performance: After the competition, the computer will calculate the starting and ending time, fastest lap time, and ranking of each athlete, and print out the score report;
2. Display the actual game status: The information processed by the computer can be displayed on the big screen or TV screen in real time and dynamically, and the fierce game status is clear at a glance;
3. Save game records: all game records recorded by the computer, available for viewing or printing at any time.
4. System composition and architecture
The whole system consists of five parts: integrated reader MS-R910, dual-frequency electronic tag MS-T739, 125K low-frequency ground induction coil, special software and control computer.
system structure:
Five, system equipment
1. MS-R910 type integrated reader
2. MS-T739 dual-frequency electronic label
