Abstract
The invention relates to a comprehensive diagnosis system for acceleration and intermediate run rhythms of short distance runners. The comprehensive diagnosis system integrates a plurality of devices such as a pressure sensor, an acceleration sensor, a laser velocity measurement device, an exercise camera and a data acquisition unit by the aid of a computer technology and characteristics of various devices to achieve multi-device synchronous testing and rapid diagnosis and feedback and is a comprehensive application system. The system is mainly applied in the sports science and technology and exercise training and guiding of linear sports (short-distance running, hurdling and long jumping). Currently, short distance running is taken for example, a complete testing, diagnosis and feedback system is formed, and by combining with videos shot by the system, coaches and runners can master mechanical characteristics of kicking actions of double feet, kinematics characteristics of limbs and kinematics characteristics of body postures of the runners at the starting moment and kinematics characteristics of body actions and body displacement speed rhythm characteristics during accelerative running and intermediate running and the like visually and rapidly. Meanwhile, theoretical bases are established for analysis of speed distribution and generation reasons of all phases, a large number of data supports are provided, and a test result database of excellent runners is built.
Description
affiliated technical field
Product of the present invention is a kind of synchronism detection and diagnostic system of integrating many equipment such as pressure sensor, acceleration transducer, laser velocimeter, Flying Camera and data acquisition, can be applicable to sports and scientific research, sprint training, jumped in the fields such as training in the training of hurdling, length.
technical background
At present, focus on very much abroad the rhythm characteristic of dash full run, for example, after the World Track and Field Championship in 2009 of Germany's NRISS, just announced Bo Erte when the world record of creating 9.58 seconds, his every 10 meters of segmentation used times and speed are respectively 1.89s/5.29m/s, 0.99s/10.10m/s, 0.91s/10.99m/s, 0.85s/11.76m/s, 0.83s/12.05m/s, 0.82s/12.20m/s, 0.81s/12.35m/s, 0.82s/12.20m/s, 0.83s/12.05m/s, 0.83s/12.05m/s, maximum speed is 12.27m/s, appear at 65.03 meters of
[1].This VELOCITY DISTRIBUTION result is used laser velocimeter tracker to follow the trail of the running velocity in Bo Erte whole process and obtained.At home, the equipment of the same race that the Shanghai researcher Xu Yicheng of institute of body section also adopts German import carried out research to the omnidistance speed of Liu Xiang's hurdle race, for the technology of science, objective understanding intermediate run and rhythm distribute, provided reliable basis.But, same category of device lacks at home at present, especially will test the off equipment such as accelerometer (element) synchronous operation of pedaling the pressure sensor of the power of stretching, testing link motion in this system, the visual angle that multi-angle, multisystem merge is disclosed the equipment of profound mechanism and is not yet found, and does not also find relevant report in document.
At present, the block of using in domestic contest is to come monitoring moving person in the time interval of firing a shot and having an effect by a pressure sensor is installed, and rule predetermining " pedal after firing a shot the time that the power of stretching surpasses 30Kg be less than 100ms, report to the police ", sentences and fly.The block using in training does not have sensor installation.What the present invention designed is independently to install, arrange pressure sensor for each pedal, every pin of independent test is being pedaled the pressure (pedaling the power of stretching) that produces in extending through journey, action time, explosive force index, left and right time difference (balance is firmly) etc., for the science judgment sportsman start of a race pedal while stretching about the feature of having an effect of both legs objective basis is provided.
Domestic, acceleration transducer technology, in field extensive uses such as Robot Design, model aircraft flight controls, realizes responsiveness measurement, attitude control etc. by the programme-control of setting.And use acceleration transducer to be applied in the record and feedback of player motion feature, not yet find relevant report.The present invention adopts acceleration transducer and wireless communication technology, realizes the swing speed of each link of lower limb and angular pose and running speed are measured in real time, for disclosing body segment's motion, on the impact of human body integral translational speed, provides theoretical foundation.
Domestic, radar velocity measurement, laser velocimeter etc. have been widely used the measurement fields such as (electronic police test the speed) of testing the speed.But because speed, the test object area of its measurement are larger; Yet this technology is not suitable for the velocity test to human body, because human motion speed is slower, the speed of running is fast generally 30m/s, moreover is to accelerate from static beginning; In addition, people's bulk area is less, therefore the measuring accuracy of speed measuring equipment is proposed to high requirement, and acquisition technique is proposed to requirements at the higher level.The present invention adopts low speed laser velocimeter equipment, adopts C# language programming, has solved this difficult problem, realizes the requirement that measuring accuracy is higher.
Flying Camera is very universal, is widely used in life and training feedback, and still, the system that the equipment such as Flying Camera and pressure test, acceleration survey formula, laser velocimeter are combined is not yet found.By integrating, solved the unilateral defect of individual system, and the asynchronous collimation error of bringing.The present invention, by the simultaneous techniques of these equipment is processed, has realized from multisystem, the whether reasonable objective basis of multi-angle judgment technology.
Summary of the invention
In order to overcome in training at present, use separately the deficiency of these equipment, the invention provides a set of integration system, this system can not only be tested omnidistance speed rhythm, and kinematics character and dynamic characteristic can be combined effectively, athletic velocity characteristic can either be reflected intuitively, the dynamic characteristic (the swing feature of leading leg) that produces this speed can be reflected again.
The technical solution adopted for the present invention to solve the technical problems is:
1) off system
In the design of traditional block, for each vola Pedalling, two three-dimensional pressure sensors are installed.Sensor can real time record sportsman at the power that scrunches---the time graph of two pin in block clearance time left and right, therefrom find scrunch power peak value, peak value constantly, the parameter such as relatively of the direction of power and variation, left and right both feet.
2) accelerometer and data collecting system
Native system adopts 10 3D accelerometers (range is 10 ~ 24G), is placed in respectively athletic bilateral wrist joint, elbow joint, hip joint, knee joint, ankle-joint; 2 3D accelerometers (range is 10 ~ 24G), are placed in respectively athletic C7 and third lumbar vertebra, and then can obtain the intercoordination of movement velocity, acceleration, change in location and each artis of human body and each link.
3) laser velocimeter system
More ripe technology is low speed laser velocimeter technology at present, the higher 0.1m/s of precision.Native system has adopted the low speed laser velocimeter equipment of import, uses the interface of equipment and the Real-time Collection that C# language programming technique is realized signal.
4) image capturing system
Main employing with the image pick-up card of 1394 port PWM-280E high-definition cameras and 1394 interfaces realized Real-time Collection and the storage to video recording.Its synchronization point point is mainly to realize by external sychronisation.
5) sync control device system
Adopt wired and wireless communication technique, exploitation special circuit plate and interface card, carry out synchronous acquisition after digitlization by the multimachine signal of the equipment such as pressure sensor, accelerometer, video recording, laser velocimeter.
