The Research Of Display Apparatus For Far The Project Jump On The Line Jumped

Track and field sport, as a kind of comprehensive sports, is a combination of speed and endurance, strength and skills. It is the world's most popular sport, and is also the oldest sport. 776 BC, the first of the ancient Olympic Games on the race track and field sports is one of the items. From the first modern Olympic Games in 1896 athletics is listed as congress since the main projects. By the time of walking and running calculation results of the project, called "track". With highly and far degrees grade leap, throwing program called "field", athletics track and field and almighty is the full name of the game. Athletics and swimming, shooting is regarded as an olympic gold medal, Track and field is also the most of the olympic gold,the track and field had to be the "and the resulting.Science and technology as the catalysts and the development of modern society, it is not only create huge leverage necessary material foundation and a good social environment, but also provides a strong spiritual motive and intellectual support, creating unprecedented strong productivity. Modern economy economic globalization has occurred in the labor market globalization concept of globalization. Because of the development of science and technology, information technology makes information transfer is faster, more convenient. This is the formation of global economic coordination mechanism to provide the possibility. The international exchange of scale, speed and structure also, great changes have happened to the production and consumption, countries can more and more on world markets. At the same time, along with the arrival of the new technology revolution has information technology as the core of the emerging industry arises at the historic moment, drive the new industry chain, improve industrial structure. Of course, it also means for high quality talented person's demand social rapid expansion. Because of this, many countries have through the popularization; improve social members scientific and cultural knowledge in order to improve the quality of the social members, in order to better understand the world to change the world, to promote its development.With the rapid development of high-tech, science and technology permeates gradually to sports all aspects of the use of hi-tech means auxiliary sports has become to many countries scholars study center. Sports competitions by scientific rationalize, also gradually more attention, so as the auxiliary means sports contest the referee high-tech products also emerged in multitude. For example, in international and domestic competition, terminal electric timing, laser range finder, electronic anemometer etc widely application. But in international and domestic all levels of the game, still depend entirely on the umpire's gross judgment jumping project athletes success jumping, and the use of high-tech electronic instrument means it is rare for judgment. In general a low level of games, most commonly used in the forefront, pull a takeoff move string. When athletes when jumping caused touch twine, static state cord the change, the referee will decisions this jump is invalid. In the actual game, because time is very short jumping, often the referee is very difficult to see whether foul, athletes. In very close to the string and only when the referee according to whether string and changes to favor. This will have a miscarriage rate and cause a lot of unnecessary disputes. For the athletics game more fairness, justice and openness and exact, to get good grades and referee athletes cut to create a good game holding environment, so I chose "far degree programs to jump line on the subject developed foul display". This study used material collocting, and experimental method for research.The instrument is mainly embodied in the innovative research using laser extremely tall brightness, orientation, frequency and phase features such as a single consistent, combining with the warning device replaced the traditional of jumping project competition pattern, so as to better reflect the sports the principle of fair competition. This study is the core of using a laser light penetrates ability, monochromatic good, energy consumption advantages, even in mist windy weather cannot be affected by external influence. The use of laser gun is in working voltage 5v, athletes to cause any damage, and low energy consumption, accord with energy conservation and environmental protection principles.
