Multipurpose running imaging timing system

Abstract

The invention relates to the technical field of track and field timing, in particular to a multipurpose running imaging timing system. The multi-purpose running imaging timing system includes a starting point and an ending point. The starting point is composed of an infrared foul detection device and a wireless issuing device. The ending point includes a wireless receiving device, a high-speed integrated camera device, an end point master control device and a timing computer terminal. It is used in multi-lap middle and long-distance races. The finish part also includes an infrared sprint detection device and an RFID card reader. The runners wear vests with RFID tags. The invention integrates various technologies such as imaging, wireless communication, RFID identification, infrared sensing, and computer software, has a high degree of automation, traceable results, high cost performance, and fully meets the requirements of sports competitions and tests for grassroots school users, especially The requirements of physical examinations for high school entrance examinations and physical examinations for college entrance examinations can completely solve various imperfect problems in the existing automatic electronic timing systems on the market.

Description

Technical field [0001] The invention relates to the technical field of track and field timing, in particular to a multipurpose running imaging timing system. Background technique [0002] Running is the simplest and most effective way of exercising, so running competitions and running tests are also the most basic items in sports competitions and tests. Running timing is the basic method of judging runners in track events and tests. Running timing method and device have hand timing and full-automatic electronic timing at present. [0003] Manual timing is accomplished by a timer operating a stopwatch. The timing method is as follows: [0004] Timing of a sprint race: Starting from the smoke or flash of the starting gun, the timer starts the stopwatch, and stops at the moment along the vertical plane when any part of the athlete's torso (excluding the head, neck, arms, hands, feet) reaches the finish line. surface. Long-distance running race timing: starting from the smo...

AI Technical Summary

Problems solved by technology

[0006] (1) Competitions and tests require many timekeepers, heavy workload and low efficiency;

[0007](2) Timing errors caused by the timekeeper's visual errors and operational errors;

[0008] (3) When several athletes reach the finish line at the same time, it is difficult to distinguish the rankings, or there may be omissions or errors in records;

[0009] (4) The workload of grade checking is heavy, mistakes are prone to occur, and once a problem occurs, it cannot be traced accurately

[0017]1. The price is too high, generally more than RMB 300,000, which is not suitable for grassroots users (especially school-level users)

[0018]2. It cannot fully meet the timing requirements for the multi-lap middle and long-distance race, which requires manual lap recording, and the number of participants should be controlled at 10 within a person

[0024]1. The timing error is relatively large. Since the identification by RFID is within the scope of the area, there is no precise control of the finish line, so it is impossible to accurately lock the time at the moment of crossing the line

Especially not suitable for sprint events

[0025]2. Once a problem occurs, it cannot be traced accurately

[0031]1. Infrared timing equipment can only record the results of athletes crossing the finish line, but cannot judge the ranking order of athletes crossing the finish line. When many athletes cross the finish line at the same time , cannot record the performance of each athlete

[0032]2. Once a problem occurs, it cannot be traced accurately
