The Design And Implementation Of Technical-Tactics Statistics And Analyse System Of Volleyball Match

Sports computing is a course to apply to data mining in the filed of sports especially in compective sports.Recently,Physical compute become a popular research filed. It has been agreed that the applying of high science and technology such as computer technology can improve the level of skills in sports competition as more and more effects of Volleyball match to the world. Some countries or districts with high sports level invest lots of fund in the area.There are still some problems in the physical compute research on the filed of volleyball match. The collection of data can not satisfy the request of real time. Simultaneity, face to the huge amount of data,choosing a suitable arithmetic of data mining and buliding a suitable model are also difficult.On the aspect of data collection,DataVolleyball is the a very famous software on analysing the data of volleyball match. It present a script based on process. But only keyboard can be used to collect data, and the design of script can not satisfy the request of real time completely. This paper present a solution to improve the speed of data collecting. On the aspect of collecting method, it integrate the methods of using keyboard and using mouse, improve the speed of collecting by find the high frequent scripts. On the aspect of collecting script, it presents a script based on mode using codes,coding a series of action modes on the volleyball matchs, and concluding the scripts by decoding system, and improving the efficiency of collecting. The experiment proved the correctness and feasibility of the solution.On the aspect of data analysing, this paper analyse the difficulty of applying the data mining arithmetic to the technical-tactical analyzing of sports. It gives 3 solutions of mining the key factor of scoring in volleyball matches. By calculating system reliability difference, solve the problem of finding focal process of action transitions.By sorting and finding the high frequent scripts, solve the problem of finding relational compoundings.By simulating linear regression, solve the problem of forecasting the success rate of compoundings by the least-square method. The experiment proved the correctness and feasibility of the solution.In addition, a system of Technical-Tactics Statistics and Analyze System of Table Tennis Match is designed and completed. This paper introduces the system structure, data model and functions particularly, and gives the result of testing. This system solves the problem of analyzing by manual work. The coach can analyze the data of match by this system. This system can provide some advice for the coach to make decision.
