Multi-person walking race system based on semi-active RFID electronic tag

Abstract

The invention discloses a multi-person walking race system based on a semi-active RFID electronic tag, and the system comprises an active RFID card reader, a 125KHZ low-frequency exciter, a double-frequency semi-active RFID electronic tag, a liquid crystal big screen, and an upper computer server. The 125KHZ low-frequency exciter is used for enabling a 125KHZ signal to cover a start line in a playing field, activating a 125KHZ signal of the double-frequency semi-active RFID electronic tag, and enabling the double-frequency semi-active RFID electronic tag to emit a 2.4GHZ signal. The active RFID card reader receives the 2.4GHZ signal emitted by the double-frequency semi-active RFID electronic tag. The active RFID card reader transmits the read tag signal to the upper computer server, and the upper computer server receives and processes the signals, and then transmits the processed signal to the liquid crystal big screen for displaying the number of cycles and a current place in a competition in real time. The system can achieve the full-automatic statistical operation of the scores of athletes, can display the scores of the athlete in real time, can give the scores after competition, and is accurate, instant and fair in statistical result.

Description

technical field [0001] The invention relates to the technical field of sports competition trajectory management, in particular to a semi-active RFID electronic tag-based multi-person race walking competition system. Background technique [0002] Race walking competitions in sports competitions are different from ordinary daily walking. The rules of race walking stipulate that the supporting legs of the competitors must be straightened, and the transition from single-foot support to double-foot support is required. Ordinary daily walking speed is about five kilometers per hour, while the speed of race walking is much faster, even at a moderate speed, it is more than double the speed of ordinary walking. In addition, race walking has two other characteristics compared to ordinary walking: 1. The race walking distance is relatively long, such as 20km; 2. There are more people participating in race walking competitions, generally more than 50 people. [0003] Today, when vigoro...

Problems solved by technology

However, due to the large number of participants in the race walking competition and the large number of laps in a race, if the statistics of the race walking competition are completely relied on by the referee, errors and omissions will easily occur.

At present, in order to achieve accurate and effective results, it is generally necessary to invest in multiple referees to record laps and time, and the results after the game need to be summarized and analyzed. Generally speaking, the statistical process is time-consuming, labor-intensive, and low-efficiency.
