Students 'physical training as well as the examination standard are the basic requirements of students' physical training. However, for a long time, the training of multiplayer training and the cumbersome examination of many people have always been a difficult and long-standing problem.
Based on this, students using the RFID technology, physical training and assessment system to solve the 1000, 800 meters, 200 meters, 100 meters, 50 meters running subjects at the same time training, assessment timing, counting circle, counting problems. When the training examiners carrying the movement timing chip tag through the timing coil antenna, the timing coil antenna will receive the RFID data signal of the timing chip tag connected to the timing reader connected to it, the timing reader to record the current time And timing chip tag related information, that is completed timing, counting circle, counting function. Competition results can be displayed in real time, the training organizer can be installed on the computer timing system software to view, edit, print the results.

Fourth, the system hardware components and products
Sports timing system reader (trigger reading and writing integrated reader)
Sport Timing Chip (Electronic Tag)
125K sense coil antenna (low-frequency cable antenna)
Operating system server platform (sports timer system)
When students with double-frequency electronic tag through the runway timing coil, 125K low-frequency activated antenna can immediately activate the dual-band electronic tag information, dual-band electronic tag in real time to actively send data to the reader, the reader will read Of the card data uploaded to the connected computer, the computer get the athlete's information, and record the corresponding moment when passing, with special software for a series of processing of the information. The start time of running can be collected by the "Timing Start" button of the reader and uploaded to the background software of the computer. The background software collects the start time and the card information corresponding to the corresponding athlete information, and statistics the competition conditions to achieve running The purpose of automatic timing project.
The system is laid at the end of a set of 125K to sense the coil antenna for the movement of the clock system lap system.
When a student carries a dual frequency chronograph chip tag through the timekeeping carpet antenna, the carpet antenna sends the received RFID tag response signal to its associated reader, which reads the current time and tag information, ie, completes Timing function. Competition results can be displayed in real time, the referee or training organizer can view, edit, print the results through the timing system software installed on the computer.
Five, system advantages
Real-time high: in the field once the label is triggered, immediately upload data, software processing timing information and statistics and time rank information stored in the database;
Strong anti-interference: the human body, metal, dust, moisture will not have any impact on the system, product robustness through rigorous testing;
Installation of equipment convenient: product design fully consider the ease of installation, 125K low frequency and 2.45G dual-band integrated read precision timing requirements, not to lay other equipment, the card issued with the software can be achieved in the long-distance running chronograph lap application;
No crosstalk event occurs: When the same frequency or different frequency high-power microwave equipment used simultaneously, the product will be flexible frequency hopping to avoid interference sources;
Large data capacity: The system uses 2.45G band reader as the main channel for data circulation, data communication rate of 2Mbits / S;
Multi-label recognition at the same time: Each card reader can simultaneously identify 200 cards in the card reader area, no collision without crosstalk;
EMI, EMS ability, the card launch power of one-thousandth of the phone transmit power, green, no electromagnetic radiation hazard. Will not conflict with Bluetooth, 802.11, Wireless LAN;
Low power consumption, long life: the electronic tag will only send data when it enters the trigger coil of the local coil. When the coil does not enter the coil or the coil coil is in the same sense for a long time, the tag will be dormant, which greatly reduces The power consumption of electronic tags, extending the battery life;

Timed carpet / induction coil
1) dual-frequency movement timing induction coil needs to be connected with the electronic smart timing host to complete the timing function. When the timing induction coil receives the response signal from the dual-frequency timing chip tag, the read head records the current time and the tag ID number. Timing induction coils can be used in a variety of environments and are waterproof and can be used for running, cycling and snow sports; rugs are fairly durable.
2) Induction coil contains a separate induction circuit (125kHz wake-up for tag activation) and receive loop (2.45G receive tag response signal). Sometimes the resonant frequency of the loop can be affected by the surrounding metal objects (such as reinforced concrete, water pipes, etc.), thus affecting the reading distance. To this end in the reading head contains a special automatic tuning circuit, this effect will be reduced to a minimum.
