With the development of the modern science and technology, new and high technology and the electronic instrument and equipment has been widely used in the referee work of the large scale track and field matches, which is also a prominent feature of the modern large scale track and field matches. Taking the referee work of the track and field match of the Ninth National Games as an example, this article carries on the discussion on the function of the electronic equipment in the large scale track and field competition, to provide a reference for further deepening the recognition and understanding of the characteristics of the modern large scale track and field matches.
Present situation and the development of the sports electronic equipment
Since the development of modern Olympic sports competition, sports have become a part of peoples life around the world. For more than 100 years, with the continuous improvement of the level of the competitive sports, the competition has become increasingly fierce, and in the competitive sports games, ranking the performance in one second per one hundred, or even one per one thousand seconds is very normal. So, quickly, accurately and fairly determining the timing and scoring of the achievement, and the instrument and the equipment assessing the scores have become one of the necessary sports facilities of the development of competitive sports. Early in the seventeen sixties, in the sports games there was the application of the mechanical stopwatch, and until the forties of this century, the development of light, machine, electric technology is gradually applied to the referee equipment of the sports matches. In the sixties of this century, the Swiss Omega company as the representative successfully promoted the timing and scoring devices to the sports industry with various applications of the electronic technology as the leading factor in the sports competitions, and has won the identification of the international sports organization. The increasing application of these electronic devices in sports competitions accelerates its development, and internationally the German Junghanns, the Japan Seiko and other companies also joined this field of research, with the development of their own products. In the eighties, with rapid development of the computer technology, and the appearance of various new materials, sports electronic equipment has reached a new level in terms of its reliability and automation. The use of the electronic judgment devices of the games, which can also promote the improvement and development of the sports electronic equipment, is clearer and clearer in the technical definition.
Sports electronic equipment can be roughly divided into three categories. The first category is mainly the electronic equipment used in the automatic and semiautomatic timing and scoring of various sports competitions and the scoring system, such as track and field, swimming, weightlifting, rowing, winter sports, cycling, gymnastics, diving, all kinds of ball games, shooting, fencing etc. The second category is the various auxiliary training and monitoring equipment and instrument used for scientific sports training, to improve the sports performances, such as the swimming start, the Turing test, rowing strength telemetry, eight first telemetry, heart rate telemetry, photoelectric detection of firing stability, and the electronic equipment related to the athletes material selection. The third is the computer information system of the large-scale comprehensive sports games, such as the Olympic Games, the intercontinental games, and the National Games. The host countries and cities are using the competition opportunity to demonstrate its economic and technological strength. In addition to providing the first-class modern venues, the electronic information system has become one of the main equipment of the system during the general assembly, for journalists, sports teams and the public to understand the relevant information, it also provides the games with all service guides, to make the system function more and more complete, and more convenient to use. No wonder some people comment that the games of the Olympic level have become a window to display the technological progress and development of the world.
Study and discussion on the sports electronic equipment
Fully automatic electronic timing system The Ninth National Games use the SEIKO (2000HD) automatic electronic timing system for the timing, and this system is one of the world's most advanced timing systems, which is characterized by high resolution images, with the image resolution 419 million pixels (2048@2048H), more accurate interpretation, with the interpretation precision of the images up to 1/4000s, and large recording capacity, with the single 322MB and the dual 644MB, and one side recording 250 screens and the double 500 images, and the resolution up to 400dpi. The full automatic electronic timing system can print the color images of the athletes through the end after being amplified with the resolution 1/1000s, which effectively distinguishes the ranks of each athlete arriving at the end position and accurately judges the competition performance of the athletes. For example, in the men's 100m finals of the National Games, the performance of the top two is 10.25s, and their winning or losing is determined by 1/1000s. From the nineteen sixties, the large international track and field competition began to use the electric timing, and the current track events of 400m and below only admit the electric timing of the world and the national record.
