Description
Affiliated field: the present invention relates to the athletic training automatic field, particularly a kind of long-jump training system based on ergograph and digitlization runway.
Technical background world today field circles have stepped into a new frame that a hundred flowers blossom, and the track and field competition is growing more intense, and new force continues to bring out.Simultaneously, present situation from world's track and field sports development, have certain development disequilibrium and the intercontinental distribution characteristics of remarkable advantages project comparatively: the track and field sports development leveies of Europe and American States are higher, and the track and field sports integral level in Asia is relatively low.Though China's track and field event has certain basis in events such as woman's middle-distance race and footrace, man's 110 meter high hurdle, repeatedly obtaining prominent success in the Olympic Games and the world's track and field competitive bidding match, but still be in backward status on the whole in the world, especially bigger with the American-European countries gap on projects such as triple jump, long-jump.Change this situation just must break traditions training mode, pay attention to training method and means improvement, strengthen tackling of key scientific and technical problems dynamics, improve the scientific and technological content and the scientific level of training in the track and field sports training process.
The long-jump project is technical very strong, and wherein run-up and take-off and long jump result are closely related, is most important two links, also is the link of difficult assurance.The task of run-up is exactly to obtain the highest run-up speed, and for accurately technology, health and psychological preparation are carried out in pedal and fast and strong take-off; Take-off requires the sportsman under the prerequisite of the highest run-up speed, in the extremely short time, finishes-serial take-off action by correct order, thereby obtains big as far as possible rise initial velocity and the suitable angle of rising.
Scientific training tool at long-jump is also relatively deficienter at present, main subjective artificially judgement and special ability are taken exercise and are improved, also there is minority to lean on high speed video recording analysis system and device for measuring force to obtain the kinematics information of training process, with this evaluation analysis Motion Technology, this analytical work amount is big, and the equipment complexity is loaded down with trivial details, and is subjected to the constraint of scene variation and calibration system, can only obtain local process information, the expense costliness.Comprehensively obtaining of the dynamic information of the whole process from the run-up to the take-off, have not yet to see the method and apparatus of system, and dynamic information is to analyzing, estimate long jumper's sports tactics ability, find the method for improving technological deficiency very important, especially dynamic informations such as the angle of the speed of run-up, rhythm, stride, direction and take-off, speed are the keys that improves long jump result.
According to new patent searching, the broad jump system with image positioning that is used for the long-jump training, application number is: 200710114089.4, publication number is: CN101433757A, mainly by running position line, scratch line, penetrate as track, penetrate the image synchronous display system that camera, camera car and display form and obtain athletic motion process image, its advantage be utilize synchronous image and display system can make the sportsman see own in training process step whether step on running position line and scratch line, thereby reach correction motion person's state of the art, reduce the take-off error.But the equipment complexity that this method is used costs an arm and a leg, and specific aim and artificial subjectivity are too strong, and the integrated information that is not suitable for the long-jump training is obtained and scientific evaluation.Present domestic long-jump competition training press for by obtain the sportsman in the run-up process the movement rhythm parameter and take-off process in play hop-information, the long-jump process is carried out the analysis of science evaluation, to improve training achievement.
Summary of the invention the objective of the invention is to: in order to overcome defective and the deficiency in the existing long-jump training, improve the science and the training effect of training, a kind of novel long-jump training system based on ergograph and digitlization runway is proposed, kinematics and the dynamic information that obtains carried out analysis-by-synthesis, thereby to the training guidance of long-jump campaign proposition science.
Technical scheme of the present invention is: a kind of long-jump training system based on ergograph and digitlization runway, form by digitlization runway module, fieldbus, force-measuring module and computer, it is characterized in that: ergograph and be covered in force-measuring module and the digitlization runway module upper surface level that the take-off board, protective layer of ergograph upper surface constitute and join constitutes the integrated information of long-jump campaign from the run-up to the take-off and obtains platform; The digitlization runway that is made of bottom, flexible sensor array and circuit and surperficial plastic cement is finished the space-time sequential parameter collection of paces in sportsman's run-up process; the collection of the distributed constant of the space-time power the when force-measuring module that is made of ergograph and springboard placed on it and protective layer is finished sportsman's take-off; be sent in real time in the computer by fieldbus after information via A/D conversion that digitlization runway and ergograph obtain and the data preliminary treatment, utilize supporting software to analyze, show.
Described digitlization runway module is a plurality of sensors collection arrays to be pasted between bottom and plastic layer be fixed on the ground, each sensor collection array is connected to data pre-process circuit separately, and a plurality of pre-process circuits are connected to computer by being affiliated on the data/address bus.
Described ergograph is sextuple power ergograph, and level places underground, and upper surface is take-off board and protective layer fixedly, and protective layer is between runway and take-off board.
The described long-jump integrated information that is made of force-measuring module and digitlization runway module is obtained the axis of platform before according to the place the jumping pit and is placed, and constitutes the long-jump training system jointly with the computer data processing module.
The present invention with respect to the beneficial effect of prior art is:
One places the sensor array between bottom and the surperficial runway plastic cement in the digitlization runway module, can obtain the paces information of sportsman in the run-up process; When the sportsman trains thereon, parameters such as the shape that sole contacts with runway, position, sequential all can be collected by sensor array, after the filtering of process data preprocessing module, the A/D conversion, be sent to Computer Analysis by fieldbus, can obtain the information such as step-length, speed, direction and movement rhythm of run-up process by the position time sequence information, for training provides objective, analysis of science foundation.
They are two years old, the ergograph sampling time interval is very short, can accurately obtain the distribution of sportsman, comprise the variation of the power size of X, Y in the whole take-off process, three directions of Z, from obtaining take-off angle, take-off speed, direction of take off at the non-coplanar force of setting foot on springboard and take-off moment.
Its three, when this training system time spent not, remove take-off board and protective layer on digitlization runway and the ergograph, cover the place plastic cement can recover to satisfy generally use the training court.
Its four, this training system not only can be used for long-jump, can also be used for other sports item that needs such as triple jump, vault obtain movement rhythm and force information.
