Description
Technical field
The present invention relates to a kind of vollyball velocity measuring technique field, specifically, testing the speed particularly to a kind of vollyball is
System.
Background technology
Employing sound, optical, electrical, artificial intelligence and robotics, build a volleyballer and block training
With instruct system, this system under battle conditions can carry out athletic training with simulated field, makes training athlete
Process has body to face the most on-the-spot sensation.Can use according to the weakness in China's athlete's technique and tactics simultaneously
Computer-controlled mode carries out virtual dual training targetedly, and block athlete is trained block every time
Effect carries out real-time, concrete and digitized analysis and evaluation, enables athlete more truly, visually
This block that solves oneself and the preferable gap blocked and improvement direction；Science is provided for coach athlete
Digitized foundation accurately.Vollyball velocity-measuring system is crucial, and existing testing the speed cannot meet this demand.
Summary of the invention
The technical problem to be solved is, for above-mentioned deficiency of the prior art, to disclose one
Vollyball velocity-measuring system, the little low cost of its volume, stable, it is possible to meet pitching robot system to testing the speed
The precision of subsystem and control requirement.
The technical solution adopted for the present invention to solve the technical problems is: a kind of vollyball velocity-measuring system, including electricity
Source module, controller, filter amplifier, microwave remote sensor, transmitting antenna, reception antenna, service machine
People controls computer, LCD display module and relay indicating light；Described power module and filter amplifier all with control
Device processed connects, and described controller uses dsp processor and is provided with embedded OS, and described microwave passes
Sensor is connected with filter amplifier, and described microwave remote sensor is provided with transmitting antenna and reception antenna, described
Pitching robot control computer be connected with controller, described LCD display module and relay indicating light all with control
Device processed connects.
As a kind of preferred implementation of the present invention, described controller is provided with data storage.
As a kind of preferred implementation of the present invention, described microwave remote sensor uses HB100 microwave sounding to pass
Sensor.
As a kind of preferred implementation of the present invention, described controller is provided with A/D modular converter.
Operation principle: when pitching robot ready serve, controls computer and gives notice signal to being arranged on
Speed measuring device on pitching robot, velocity-measuring system is activated entrance working immediately, when vollyball is sent out
When going out to enter radar volume, system shows the release speed of vollyball in real time, and this velocity information can be admitted to
Pitching robot controls computer as the input quantity controlled next time.
Utilize one in built-in two ADC channel of controller the low frequency Doppler signal after amplifying is carried out
Sampling, utilizes the DSP function of controller that the digital signal after analog digital conversion is carried out spectrum analysis, extracts
Frequency corresponding to the strongest frequency component of power therein is Doppler frequency, thus calculates going out of vollyball
Hands speed.
The present invention compared with prior art has the advantage that
A kind of vollyball velocity-measuring system disclosed by the invention, the little low cost of its volume, stable, it is possible to meet
Pitching robot system is to the precision of the subsystem that tests the speed and controls requirement.
