Description
Technical field
The utility model is related to table tennis specialized training auxiliary devices, and in particular to a kind of table tennis specialization step movement speed
Spend training system.
Background technology
The movement of table tennis specialization step is very important one in table tennis technology, according to investigation, applied to table tennis
The training method and equipment of special step movement more lack.The focus of people is neglected always on table tennis or racket
People has been omited, thus has been badly in need of the device of the step translational speed of exploitation training of human.
If detecting the movement velocity of sportsman, generally can on athletes ' body mask wearing time sensor, still
The motion detection big for motion range of velocity sensor is more effective, for this small-scale motion detection of table tennis not
It is enough accurate.Also, the orientation that sportsman moves in table tennis directly affects balling effect, and velocity sensor is difficult to determine fortune
Mobilize mobile orientation.Therefore need to design a kind of training device that can interpolate that sportsman's motion direction.
The content of the invention
In order to facilitate the step translational speed and orientation of people in detection table tennis training, the utility model provides a kind of table tennis
Ball special project step translational speed training system.
A kind of table tennis specialization step translational speed training system, including piezoelectric transducer, chromacoder, computer,
Display and ping-pong table, it is characterised in that：Several piezoelectric transducers by the netted ground being laid on by ping-pong table and with
Chromacoder connects, chromacoder connection computer, computer connection display.Computer can control display, make to show
Show idsplay order motion picture on device；Sportsman responds rapidly according to instruction action picture, when sportsman is mobile and steps down in
When in piezoelectric sensing system, piezoelectric transducer can generate the piezoelectric signal with location information, and chromacoder identification should
Piezoelectric signal is simultaneously converted to digital signal（Referred to as responding digital signal）, responding digital signal reaches computer, and computer for analysis is rung
Answer digital signal, draw the action of sportsman whether in place, whether reach rate request, show result over the display.
Further, the chromacoder includes converter and encoder, several piezoelectric transducers
It is connected respectively with converter, converter connection encoder, encoder connection computer.Converter can be by piezoelectric transducer
Piezoelectric signal（Analog signal）Digital signal is converted to, which is converted to responding digital signal by encoder.
Further, elastic insert is further included, several piezoelectric transducers press latticed embedded elastic insert, elasticity
Setting cushion is on the ground by ping-pong table.
Preferably, piezoelectric transducer is the netted laying of the cm of 10 cm × 10 by single grid.
In use, pre-setting some instructions motion picture in computer, sportsman stands on the region of piezoelectric transducer covering；
Idsplay order motion picture in order on display, sportsman respond action, and the foot of sportsman will step on difference successively
The piezoelectric transducer of position, piezoelectric transducer generate piezoelectric signal, and piezoelectric signal is converted to responding digital by chromacoder
Signal, using computer by responding digital signal and instruction action picture comparative analysis, so as to judge the situation in place of step, reaction
Speed, display can show result.In this way, sportsman can improve reaction speed according to instruction action picture repetition training.
The beneficial effects of the utility model：Step translational speed and orientation can be measured, is conducive to train table tennis specialization
Step moves；Can be controlled by computer automatic idsplay order motion picture and response as a result, instruction sportsman be trained, and
Without complicated operation, sportsman is facilitated to use；It is simple in structure, it is easily fabricated.

Specific embodiment
Embodiment 1
As shown in Figure 1, 2, a kind of table tennis specialization step translational speed training system, including ping-pong table 1, piezoelectric sensing
Device 2, elastic insert 3, display 4, computer 5, chromacoder 6, wherein chromacoder 6 include converter and coding
Device.By single grid it is the N number of piezoelectric transducer 2 of netted insertion of the cm of 10 cm × 10 on elastic insert 3, elastic insert 3 is spread
Before being located at ping-pong table 1；N number of piezoelectric transducer 2 is labeled as piezoelectric transducer 201, piezoelectric transducer 202, piezoelectric transducer 203
To piezoelectric transducer N, each piezoelectric transducer connects a converter, line set synthesising wire group 7 by conducting wire respectively；M
A converter is labeled as converter 601, converter 602, converter 603 to converter M（With N number of piezoelectric sensing
Device corresponds）, each converter respectively pass through conducting wire connect encoder an input terminal；The output terminal of encoder passes through
Data cable connects computer 5, and computer 5 connects display 4 by data cable.
Operation principle：Some instructions motion picture is preset in computer 5, instruction action picture is either individual picture also may be used
To be several continuous pictures.Computer 5 controls display 4 to show an instruction action picture, and sportsman responds action therewith,
The step of sportsman is mobile and some piezoelectric transducers of stepping on, no matter which position of stepping on, the composition for the piezoelectric transducer stepped on
（General every foot can step on 2 ~ 6）It can uniquely determine, i.e., piezoelectric transducer is generated with location information piezoelectric signal,
Digital signal is converted to by corresponding converter, i.e. the input of encoder is also unique, then output one uniquely determines
Responding digital signal.Whether in place 5 comparative analysis instruction action picture of computer and responding digital signal draw sportsman's response；
Computer 5 records the time point of idsplay order motion picture and receives the time point of responding digital signal, and the difference at two time points is
For the response speed of sportsman.
Arrangement piezoelectric transducer 2 as shown in Figure 3, circle represent piezoelectric transducer, and number is the number of piezoelectric transducer.It is false
The piezoelectric transducer 2022, the 2032 if initial position of sportsman is stepped on（Left foot）With 2024,2034（Right crus of diaphragm）, through converter and
Coder processes, initial position correspond to two initial digital signals（Represent initial left foot position and right crus of diaphragm position）；On display 4
Showing an instruction action picture quickly moved to the right, sportsman makes an immediate response and right crus of diaphragm moves right, left foot follow-up, according to
Secondary piezoelectric transducer 2019,2029 and 2027,2037 of having stepped on, then be sequentially generated two responding digital signals（After representing response
Right crus of diaphragm position and left foot position）, pass through two responding digital signals of comparative analysis and two initial digital signals, you can learn fortune
Mobilization moves right, i.e., motion direction is qualified.If 0.5 second prescribed response time can be regarded as speed qualification, then computer 5, which calculates, to be received
To first corresponding digital signal（Represent right crus of diaphragm position 1）The instruction action picture that is quickly moved to the right with display of time point
The difference at time point, the difference at two time points are less than or equal to 0.5 second then speed qualification, and the difference at two time points is more than 0.5 second then speed
It spends unqualified.Whether motion direction and speed are qualified, can be shown on display 4.
