1. Application background of timing system for middle and long distance running
With the gradual improvement of intelligent management and the continuous updating and upgrading of intelligent informatization hardware facilities, the application of RFID has rapidly penetrated into various industries and fields. For middle and long distance running, a simple, accurate and efficient timing system is needed. Due to the large number of participants in the middle and long distance races (3km, 5km, 10km, and race walking), the characteristics of uneven level and long sprint time determine that manual timing and automatic finish photography cannot meet the requirements of efficient and accurate statistics of competition results. In addition, long-distance running is not repeatable, which requires timing equipment to accurately and stably record and save race result data. The company uses a semi-active RFID technology automatic timing system combined with fully automatic electronic camera timing equipment to accurately determine the ranking and performance of the athletes to ensure the openness, fairness and impartiality of the competition.
2. Composition and characteristics of timing system for middle and long distance running
Background data processing middleware;
Visualize the player information input and display module;
Data storage, statistics, and export modules;
Data entry, including player name, gender number and other information
Competition grouping and competition method, you can set the number of laps of the competition
Data saving statistics export function
3. Hardware composition and products of timing system for middle and long distance running
Motion timing system reader (trigger reading and writing integrated reader)
Sports timing chip (electronic label)
125K ground induction coil (low frequency cable antenna)
Operating system server platform composition (sports timing lap counting system software)
Whenever an athlete takes a dual-frequency electronic tag through 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 will read it again. The received card data is uploaded to the connected computer, and 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.
4. Features of RFID lap counting system for mid- and long-distance running
High real-time: Once the tag in the field is triggered, the data will be uploaded immediately, and the software will process the timing information and statistics and save the time ranking information in the database;
Strong anti-interference: The human body, metal, dust, and humidity will not cause any impact on the system, and the robustness of the product has been strictly tested;
High real-time accuracy: The system has a timing accuracy of 20ms, uses GPS satellites for time service, synchronizes Beijing time, and has high time accuracy.
Convenient installation of equipment: The convenience of installation is fully considered during product design. 125K low-frequency and 2.45G dual-frequency integrated reading realizes accurate timing requirements. No other equipment is required. Card issuance and software can be used to realize mid- and long-distance running lap counting. application;
No crosstalk event occurs: When high-power microwave equipment of the same frequency or different frequencies is used at the same time, the product will flexibly hop frequency to avoid interference sources;
Large data capacity: The card reader in the system uses the 2.45G frequency band as the main channel for data circulation, and the data communication rate is 2Mbits/S;
Simultaneous recognition of multiple tags: each reader can recognize 200 cards in the reader area at the same time, no collision and no crosstalk;
Strong EMI and EMS capabilities, card transmission power is one-thousandth of the mobile phone transmission power, green and no danger of electromagnetic wave radiation. Will not conflict with Bluetooth, 802.11, and wireless local road networks;
Low power consumption and long life: The electronic tag will only send data when it enters the ground sensing coil trigger area. When it does not enter the ground sensing coil area or stays in the same ground sensing coil area for a long time, the electronic tag is in a dormant state, which greatly reduces The power consumption of the electronic tag is increased, and the service life of the battery is prolonged;
