It applies example and attached drawing is cooperated to be explained in detail.
Fig. 1 to Fig. 2 and Fig. 5 is please referred to, in the present embodiment, the detection method of take-off movement can answer in a kind of long-jump
Used in anyone in the scene of long-jump.First some professional terms in long-jump are explained below:
Flight angle: pedal moment, jump over direction and the horizontal angle of centre of body weight are left in take-off foot.
It leads leg: being done in track and field sports when making across, bounce, leg that forward upward has been put.
In the present embodiment, take-off moment refers to: the moment of pedal is left in take-off foot.
In the present embodiment, trigger sensor has been set on duckboard, and trigger sensor communicates to connect controller, and
For: pedal moment transmission take-off twinkling signal is left to controller in long-jump personnel's take-off foot；In the present embodiment, it triggers
Diaphragm pressure sensor can be used in sensor, and other sensors can be used in other embodiments.
In the present embodiment, controller communication connection first level angular transducer and the second horizontal angle sensor.
In the present embodiment, in actual measurement, first level angular transducer may be disposed at the swing of sporter
The front side of leg or thigh lateral side of femur, are used for: the angle that measurement take-off moment leads leg with horizontal plane；In other embodiment
In, the first level angular transducer also may be disposed at other positions, as long as it can measure the femur led leg and level
The angle in face.Second horizontal angle sensor may be disposed at the rear portion of sporter's waist hip, be used for: measurement take-off moment upper body
The angle of trunk and horizontal plane；In other embodiments, second horizontal angle sensor also may be disposed at other positions,
As long as it can measure take-off moment and lays out the dry angle with horizontal plane of body.In the present embodiment, using first level angle
Degree sensor and the second horizontal angle sensor, which are used for measurement angle, can also use electronic gyroscope in other embodiments
Instrument measures.
A kind of detection method of take-off movement in long-jump is illustrated below:
Step S101: take-off moment is determined by trigger sensor, and sends take-off twinkling signal to controller.It can be used

Sensor.In the present embodiment, controller communicates to connect third horizontal angle sensor, therefore receives take-off moment in controller
When signal, DATA REASONING signal is sent to third horizontal angle sensor, third horizontal angle sensor is receiving data survey
After measuring signal, data acquisition is carried out.In the present embodiment, third horizontal angle sensor is set on rear side of sporter's waist,
As long as set seated position can measure flight angle, therefore in other embodiments, there can also be other feasible setting sides
Formula.
That is flight angle step S203: is measured by third horizontal angle sensor.
Step S204: determine whether take-off is qualified according to the angle value size of rising.Can be used such as under type: can pass through by
Flight angle is sent to the controller connecting with third horizontal angle sensor, and controller determines that take-off is according to angle value size of rising
No qualification also can determine whether take-off is qualified according to angle value size of rising with third horizontal angle sensor oneself, and by result
Output.
It in the present embodiment, can also be by repeatedly obtaining the angle of first level angle value and the second level angle
Value and corresponding long-jump distance, the first level angle value and the second level angle are analyzed with long-jump distance, are generated
Invariance curve；Best angle difference range is calculated according to the invariance curve.Can be used such as under type: long-jump personnel repeatedly jump
Far, under the premise of take-off qualification, the first level angle value of its each take-off and the angle of the second level angle are repeatedly obtained
Value and corresponding long-jump distance jump in the present embodiment and obtain can intelligently be obtained by instrument at a distance, also can be with people
The data got are analyzed for input data, generate invariance curve.It can be seen that first level from the invariance curve
Angle value and the second horizontal angle angle value and the remote relationship of jump, it is described best by best angle difference range is calculated
Angle difference range is i.e. for good long jump result.
Angle value and the corresponding long-jump distance for repeatedly obtaining first level angle value and the second level angle, to described
First level angle value and the second level angle are analyzed with long-jump distance, generate invariance curve；According to the invariance curve
Calculate best angle difference range.It is analyzed by data, it is corresponding when can get the best long-jump of each sportsman apart from achievement
The angle value of first level angle value and the second level angle will effectively instruct the adjustment of sportsman's posture, quickly improve at
Achievement.

The host computer includes: trigger sensor and controller；
The slave computer includes: first level angular transducer and the second horizontal angle sensor；
The trigger sensor communicates to connect the controller, and the controller communicates to connect the first level angular transducer
With the second horizontal angle sensor；
The trigger sensor has been set on duckboard, and the trigger sensor is used for: being determined take-off moment, and is sent take-off
Twinkling signal is to controller；
The controller is used for: according to take-off twinkling signal, sending DATA REASONING signal to first level angular transducer and the
Two horizontal angle sensors；
The first level angular transducer is used for: measurement first level angle, the first level angle are as follows: take-off moment pendulum
The angle of dynamic leg and horizontal plane；
Second horizontal angle sensor is used for: the second level angle of measurement, second level angle are as follows: on take-off moment
The dry angle with horizontal plane of body；
The controller is also used to: judging whether the first level angle is whether negative or second level angle are greater than
90 degree, if the first level angle is that negative or second level angle are greater than 90 degree, determine that take-off is unqualified；If
The first level angle is positive number and second level angle is not more than 90 degree, determines that take-off is qualified.
6. the detection system of take-off movement in a kind of long-jump according to claim 5, which is characterized in that
The controller is also used to: if first level angle is negative, judgement is led leg unqualified.
7. the detection system of take-off movement in a kind of long-jump according to claim 5, which is characterized in that
Further include: third horizontal angle sensor；
The controller communicates to connect third horizontal angle sensor；
The controller is also used to: according to take-off twinkling signal, sending DATA REASONING signal to third horizontal angle sensor；
The third horizontal angle sensor is used for: measurement flight angle；
The controller is also used to: determining whether take-off is qualified according to the angle value size of rising.
8. the detection system of take-off movement in a kind of long-jump according to claim 5, which is characterized in that
The controller is also used to: repeatedly obtaining angle value and the corresponding jump of first level angle value and the second level angle
At a distance, the first level angle value and the second level angle are analyzed with long-jump distance, generates invariance curve；According to
The invariance curve calculates best angle difference range.
