The racket of energy, if a kind of training of patent CN202777704U is with tennis racket is counted, using including tennis racket, vibrating sensing
Device, counter, power supply, display are equipped with vibrating sensor at tennis catgut string perforation, be equipped at handle display, power supply,
Vibrating sensor, counter, power supply, display connection are formed circuit by conducting wire, carried out by the counter with clear device
Electronic counting, however this kind of vibrated by vibrating sensor linkage counter progress electronic counting there is meeting very appearance counts
The defects of inaccurate, to training athlete counting bring shortcoming.
Invention content
The purpose of the present invention is to provide a kind of athletic training electronic counting tennis racket, to solve in above-mentioned background technology
The problem of proposition.
To achieve the above object, the utility model provides following technical solution：A kind of athletic training electronic counting tennis
It claps mono- by racket head, signal metal water conservancy diversion vertical line, signal metal water conservancy diversion horizontal line, digital display screen, signal contact module, AT89C51
Piece machine, lithium battery, charge-discharge control circuit, claps net, throat bar, handle, charging socket composition at switch；Using stainless steel material
Make racket head, throat bar of the racket head lower number with handle, the signal water conservancy diversion metal horizontal line and letter of the inside setting intersection of racket head
The joint separation of number metal water conservancy diversion vertical line, signal metal water conservancy diversion horizontal line and signal metal water conservancy diversion vertical line.
The side setting digital display screen and switch of the throat bar, the inside setting signal contact module of throat bar and
AT89C51 microcontrollers.
The lower part setting charging socket of the handle, the inside setting charge-discharge control circuit and lithium battery of handle.
It is further described that lithium battery carries out charging source company by charge-discharge control circuit and charging socket with external electrical network
It connects；Signal metal water conservancy diversion horizontal line and signal metal water conservancy diversion vertical line contact module connection with signal, and signal contacts the signal source of module
Connecting line is connect with AT89C51 microcontrollers；AT89C51 microcontrollers are controlled by switch, pass through charge-discharge control circuit and lithium battery
Carry out power supply connection；The signal output line of AT89C51 microcontrollers is connect with digital display screen.
The principle of the invention is：Using lithium battery provide electric energy, after ball is contacted with racket head, make signal water conservancy diversion metal horizontal line with
The connection activation signal that signal metal water conservancy diversion vertical line generates is transmitted to signal contact module, and signal contact module passes received signal
AT89C51 microcontrollers are defeated by, signal is carried out accumulation calculating by AT89C51 microcontrollers according to embedded software, and calculated value is simultaneously transmitted to
Digital display screen is shown.
The beneficial effects of the invention are as follows：Electric energy is provided using lithium battery, the connection generated is contacted with racket head using ball and connects
Tactile signal is transmitted to signal contact module, and received signal is transferred to AT89C51 microcontrollers by signal contact module, and AT89C51 is mono-
Signal is carried out accumulation calculating by piece machine according to embedded software, and calculated value is simultaneously transmitted to digital display screen and is shown, can be effective
It is trained electronic counting of bouncing the ball to show, trainer can be helped to count training result, there is intelligent accurate counting, be reason
The athletic training thought electronic counting tennis racket.
Description of the drawings
The present invention is further described with reference to the accompanying drawings and detailed description.
Fig. 1 is a kind of athletic training electronic counting tennis racket schematic diagram；
In figure：1st, racket head, 2, signal metal water conservancy diversion vertical line, 3, signal metal water conservancy diversion horizontal line, 4, digital display screen, 5, letter
