Description

A kind of intelligent shuttlecock kicking tester and method of testing

Technical field

The present invention relates to a kind of intelligent shuttlecock kicking tester and method of testing, belong to sports equipment field.

Background technology

Shuttlecock kicking is the sensitive locomitivity index with coordinating quality of reflection student.This project has good bodybuilding function, and it requires that the heart arrives to, eye to, pin, and need energy high concentration, the flexibility for the stability and notice migration that strengthen attention of student has important exercise and is worth.

The main method of testing of product in the market adopts pressure sensor whether to have contact to detect tester, when its sensor recognize pressure exceed default threshold values time, counting adds 1, in adopting the method basic None-identified to be kicked or fall on the ground, also whether None-identified is that other location contacts of health are to shuttlecock to adjust action, as long as its sensor sensing to pressure exceed threshold values, just Auto-counting, and in formal shuttlecock kicking test, the number of times of Jin Ji foot shuttlecock kicking, with knee, shoulder, other location contacts shuttlecocks of first-class health, only as adjustment action, disregard number of times,

The equal corresponding a set of annex of the general each main frame of existing product, when occurring that large-scale crowd is tested simultaneously, main frame and neighbouring quantity can only increase simultaneously, improves purchase cost, add the workload of administrative staff in test process.

Summary of the invention

The object of the invention is to solve deficiency of the prior art: 1, solve the problem that None-identified in existing shuttlecock is pin or other component contact shuttlecock of health; 2, when the shuttlecock solving existing Auto-counting adopts pressure sensor, None-identified fall on the ground or tested personnel by the problem in kicking; 3, many people are solved when testing, the problems such as testing efficiency is low.

Technical scheme of the present invention is as follows:

A kind of intelligent shuttlecock kicking tester, comprise main frame and annex, described main frame is communicated by wireless module with between annex; It is characterized in that:

Described annex comprises digital 3-axis acceleration detection module, Hall element measure loop, single-chip microcomputer and sheath etc.;

Described digital 3-axis acceleration detection module, its data are from the I of this module master chip ²c interface directly reads, and delivers to single-chip microcomputer and processes; Single-chip microcomputer, according to the situation of change of its three-dimensional coordinate, judges whether that testee drops on the ground with health a part contact shuttlecock or shuttlecock;

Described Hall element measure loop is arranged on bottom shuttlecock, its pin " out " exports the signal of telecommunication to single-chip microcomputer, be high level or low level by this signal of microprocessor detect, judge shuttlecock kicked in or other location contacts of health is used for adjustment action to shuttlecock;

Described sheath includes flexible magnetic material, is worn on pin by tester.

Further, described 3-axis acceleration detection module master chip adopts ADXL345, and Hall element adopts DH481.

Further, described annex has many groups, often organizes annex and all has independently geocoding.

Further, described annex also comprises display module and acousto-optic hint module, and described display module and acousto-optic hint module are connected with single-chip microcomputer.

A method of testing for intelligent shuttlecock kicking tester, is characterized in that, described method is as follows:

(1) main frame issue start test broadcasting command start test;

(2), after each annex receives test broadcasting command, testee carries out playing shuttlecock action; Annex judges that whether effectively and count, as effectively then counting adds 1 and provides acousto-optic hint this action;

(3), after timing reaches setting-up time point, main frame issues and tests into order, and each annex of poll, read the test result of each annex successively, terminate test.

Beneficial effect of the present invention is:

1, the present invention's main frame can manage 16 annexes and easily extensible simultaneously, and all annexes all with independently geocoding, improve testing efficiency.2, annex employing of the present invention is measured tester based on digital 3-axis acceleration detection module and whether is kicked shuttlecock, a Hall element or other magnetosensitive device are installed bottom shuttlecock simultaneously, tester's both feet wear the special sheath including flexible magnetic material, effectively can identify it is the adjustment action kicking middle shuttlecock or health, thus improve accuracy.

3, the technology of this annex is adopted, when being unworthy of main frame, also can as the common intelligent shuttlecock with tally function.

4, all annexes of the present invention all can flexible configuration with independently geocoding, reduces purchase cost, decreases the workload of test and management personnel, improve testing efficiency.

 

Accompanying drawing explanation

Fig. 1 is system block diagram of the present invention, wherein 1-main frame, 1#, 2#, 3# ... annex is organized in representative more.

Fig. 2 is annex of the present invention composition system block diagram.

Detailed description of the invention

Below in conjunction with accompanying drawing, detailed elaboration is done to technical scheme of the present invention.

The intelligent shuttlecock kicking tester of one of the present invention, comprise main frame and annex, described main frame is communicated by wireless module with between annex; Annex comprises digital 3-axis acceleration detection chip, Hall element measure loop, single-chip microcomputer and sheath;

Numeral 3-axis acceleration detection module, can select ADXL345 chip to realize, its data can from the I of this chip ²c interface directly reads, and delivers to single-chip microcomputer and processes; Single-chip microcomputer, according to the situation of change of its three-dimensional coordinate, to there is reverse acceleration of gravity, thinks that testee hits with in kicking or with other position of health.

Hall element can select the DH481 of low-power consumption, and this module is arranged on bottom shuttlecock, VDD and GND is respectively working power input pin, can support that the voltage of 2.5-3.5V inputs; When there is no magnetic device effect, the pin " out " of this device exports as high level, in shuttlecock kicking process, when cover on pin has the special sheath including flexible magnetic material near this sensor, pin " out " exports as low level, single-chip microcomputer, by detecting this pin output signal, can judge whether pin contacts shuttlecock.

The single-chip microcomputer of this annex adopts low-power microprocessor, can be shown in real time and complete number of times, and provide sound and light prompt, after having tested, automatically upload its data to main frame by wireless module by display module.

Intelligent shuttlecock kicking tester involved in the present invention, is made up of a main frame and multiple annex, adopts the wireless module of existing maturation (433M module or zigbee module) to communicate between main frame with annex, and each annex is all with independently geocoding.Concrete test process is as follows:

1, each tester's both feet wear the special sheath including flexible magnetic material, and main frame issues the broadcasting command starting to test and starts test;

2, after each annex receives test broadcasting command, start timing and in being confirmed whether to be played by people according to the signal of digital 3-axis acceleration detection module or hit, again by detecting bottom Hall element or the switching signal that transmits of other magnetosensitive device, judge that whether effectively and count, as effectively then counting adds 1 and provides acousto-optic hint this action;

3, after timing reaches setting-up time point, main frame issues and tests into order, and each annex of poll, read the test result of each annex successively, terminate the test of this BT(batch testing) personnel.
