The Research And Development Of Automatic Test System For Basketball Items

At present, with the rapid development of computer technology, the test system based on PC progresses at a high speed, high-efficient, intelligent, multi-function and diversification. Therefore, fully utilizing its characteristics such as accurate, high-speed, high-efficient, convenient for encrypting and storing and strong data processing ability, applying the automatic test system to physical tests becomes an important subject which should be discussed thoroughly and solved by us.In the physical professional entrance examination for college, basketball special technology tests include running up to touch, dribbling out and home, shooting basketballs three spots per minute and polytechnic tests. The test accuracy is the base of carrying on tests scientifically, fairly and just. However, most of provinces and cities adopt artificial measurement presently, which requires several examiners who should get achievement by eyes, time, count and record achievement artificially. The method not only uses a large amount of manpower and material resources, but also is slow to test, and has many human factors. So it is apt to produce the unfair phenomena. In addition, the tests continue for a long time, which make the examiners highly centralize and tend to be tired. It is unavoidable to omit carelessly in the artificial tests. Therefore, to solve the problem, it is essential to develop automatic test system for basketball items based on PC. The system can make the test job realized apace, conveniently and accurately, which improves the science, accuracy and openness of the test. It stops the mistakes of artificial timing, counting and registering performance, which improves test efficiency, lightens labor intensity of examiners and prevents the phenomena of fraudulent practices effectively. So, under the guidance of my tutor, combining the demand of basketball-item tests, we study and develop the automatic test system for basketball items.The system is composed of the microcomputer-touching-test instrument, the microcomputer-shooting-basketball counter, the microcomputer dribbling time-recorder, recording software of touching, shooting, and dribbling scores and computer LAN. It adopts the client/server computational model. It selects Windows NT Server 4.0 as operating system for the server and Visual FoxPro 6.0 as database management system of the server and regards Borland Delphi 6.0 as developing instrument of application program for the client. It adopts 8031 single chip as the core controlling device, which makes up of the intelligent data collection end with corresponding interface circuit and sensor. The characters of it are application progress interface friendly, easy to learn and use, strong security of database andconvenient to operate.The article mainly explains the designing ideas and primary function and character of the automatic test system for basketball items, which also includes the primary technology and the principle of it and realizing method involved. Chapter one expatiates the developing foundation for the system. The purpose is to account for the feasibility, necessity and importance for the studies. Chapter two gives the whole design plan of the basketball-items automatic test system. It discusses the design of data-gather circuit, selection of network operation system, selection of data management system and selection of application-program developing tool. Chapter three and four expound the design of hardware system and recording software on PC of the automatic test system in detail. The two parts are the emphases of the text, which discusses the detail designing theory and method of the system. Chapter five introduces the operating result of it and gives the' insufficiency which should be improved further.The subject introduces computer, a modern high-performance information processing tool, into physical tests, which fully utilizes its strong logic judgment, calculation and information processing ability. The application of the basketball-items automatic test system provide...
