2.4G Active RFID Campus Sunshine Run Overall Solution For Race Timing

I. Overview of the Plan

1.1 Project Background

Currently, the "Sunshine Run" system in primary and secondary schools and universities generally suffers from pain points such as low efficiency of manual registration, cheating by proxy runners, inaccurate mileage/lap count statistics, inability to digitize and archive data, and inability to monitor students' exercise trajectories in real time . Mobile phone check-in suffers from signal obstruction, students not carrying their phones, proxy check-ins, and high power consumption. 
This solution adopts 125KHz low-frequency excitation + 2.4GHz active RFID technology , equipped with the Vanch Intelligent VD-S800 desktop card issuer, VT-S3002W active wristband tag, VI-S710XD ceiling-mounted 2.4G reader, and VI-S710 integrated 2.4G active RFID reader, to build a seamless automatic timing and lap counting management system for the "Sunshine Run." This system enables student identification, accurate lap counting, mileage statistics, trajectory tracing, anti-cheating, and automatic data archiving. It is compatible with standard synthetic track fields and outdoor running tracks on campuses, meeting the needs of daily "Sunshine Run," physical fitness tests, and long-distance running timing in sports meets.

1.2 Core Technology Principles

It adopts a low-frequency excitation combined with a 2.4GHz active identification collaborative working mechanism:

1. 2.4GHz Active Heartbeat Reporting : The VT-S3002W wristband automatically broadcasts its own ID every 4 seconds, which is continuously received by the VI-S710XD and VI-S710 readers, enabling online monitoring of the area and determining whether students are in the running track area;

2. 125KHz low-frequency precise triggering : Low-frequency excitation areas are deployed at the start and finish lines of the track/lap counting points. When students pass through these areas, they are awakened by the 125K signal and immediately upload a precise check-in timestamp + tag ID via 2.4G . The check-in boundary is clear, eliminating misjudgment, under-recording, and omissions from long distances.

3. Both readers can upload all check-in data to the campus server in real time via PoE Ethernet. The background software automatically calculates the number of laps, total distance, pace, and exercise duration to form a complete Sunshine Run exercise record.

1.3 Advantages of the Solution

1. Dual Reader Selection and Adaptation : The VI-S710XD small ceiling-mounted model is suitable for localized deployment on playgrounds; the VI-S710 high-power long-range model is suitable for full coverage of large playgrounds and long running tracks around lakes, allowing for flexible matching.

2. Strong anti-cheating measures : Low-frequency triggers only work at close range, preventing long-distance cheating outside the venue; The wristband is worn on the wrist and is not easily lent; The backend can identify abnormal speeding, turning back, and missing lap data.

3. High concurrency handling : A single reader can read more than 100 tags at the same time, meeting the needs of hundreds of people running simultaneously without packet loss;

4. Ultra-low power consumption wristband : static sleep current is only 10uA, CR2032 battery lasts for 1 year, battery is replaceable and no charging is required;

5. Easy deployment : Both readers support PoE power supply, eliminating the need for separate wiring; protection rating up to IP67, ensuring stable operation in outdoor playgrounds and rainy weather;

6. The entire process is digitalized : card issuance, attendance tracking, statistics, export, and ranking are integrated, replacing manual registration and supporting data dashboards for classes, grades, and the entire school;

7. Multi-scenario compatibility : It can be adapted to standard 400-meter playgrounds, campus lakeside running tracks, and virtual running tracks on campus roads.

4. The card issuer connects to the physical education teacher's office computer via USB, issuing cards independently without requiring a server.

IV. Core System Functions

4.1 Wristband Issuance and Personnel Management

1. Batch import student records for the entire school (student ID, name, class, grade, gender);

2. The VD-S800 card issuer reads the wristband ID and allows for one-click binding of student information;

3. Supports reporting the bracelet lost, canceling the registration, rebinding, and batch changing parameters;

4. Bracelet status monitoring: The system reads the battery level in the background and provides a notification when the battery is low to remind you to replace it;

5. The backend manages the two readers separately, monitoring their online status and signal strength in real time.

4.2 Sunshine Run Automatic Timing and Lap Counting

1. Online area determination : The wristband reports heart rate every 4 seconds, and the system uses the reader signal to determine that the student is continuously within the track, excluding those who are staying outside the field;

2. Accurate lap counting : When passing through the 125K low-frequency trigger zone, a timestamp is generated, automatically recording 1 lap, and accumulating the total number of laps and total mileage;

3. Automatically calculates exercise data: total duration, average pace, fastest lap, and average speed;

4. Customizable rules: Administrators can set the minimum daily mileage, the number of runs per week, and the valid running time period (e.g., 6:30 AM - 9:00 PM).

4.3 Intelligent Anti-Cheat Verification

1. Time verification: Multiple attendance records within a short period are identified as proxy attendance and abnormal records are automatically marked;

2. Track verification: If there is no intermediate lap checkpoint record, it is determined that the run took a shortcut and this run will not be counted as a valid result;

3. Distance verification: Automatic warning when speed exceeds human running limits;

4. Multiple wristbands for one person: If multiple IDs appear in the same location at the same time, cheating records will be locked.

4.4 Data Statistics and Visualization

1. Multi-dimensional reports: individual daily/weekly/monthly running records, class achievement rate, and grade ranking;

2. Data dashboard: Real-time number of runners across the school, total number of students who met the daily target, and list of students who did not meet the target;

3. Export function: Export all exercise data to Excel and integrate with sports fitness and health records;

4. Historical Background: Permanently saves all original timestamps of check-ins, allowing review of any student's running route.

4.5-inch large screen real-time display

The LED screen on the playground displays in real time: the list of students currently running, the real-time lap count, the daily running leaderboard, and the remaining distance to reach the target, thus motivating students to exercise.
