Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides a technical solution:
an intelligent table tennis table system, comprising:
the system comprises an actual judging device and a real-time score display screen;
the actual appraising device is divided into a judging device and a scoring device, and the judging device comprises:
the table comprises a table top 1 and a table frame 2, wherein the table top 1 is laid on the upper surface of the table frame 2, the table frame 2 comprises a base plate 21, supporting legs 22 and pulleys 23, the supporting legs 22 and the pulleys 23 are connected to the lower end of the base plate 21, and the table top 1 and the base plate 21 are arranged in a separable mode;
in the setting process of the table board 1, the separated base plate 21 can ensure that the pressure sensor 4 between the base plate and the table board 1 can be more conveniently installed and maintained for use, and a mode of directly installing the pressure sensor 4 on the surface of the table board 1 is not adopted, so that abnormal ejection caused by the fact that a table tennis ball directly falls on the pressure sensor 4 can be well avoided.
The pressure sensors 4 between the table board 1 and the table rack 2 are distributed in a dotted manner, and the distance between the adjacent pressure sensors 4 distributed in a dotted manner is smaller than the diameter of a table tennis ball, so that after the table tennis ball falls on the table board 1, dead corners which cannot be acquired by pressure cannot exist, and the accuracy of acquisition is very convenient.
Net 3, it is used for equally dividing table tennis 1 into two halves about, net 3 passes through ball rack 31 fixed connection on 2 both sides lateral walls of ball rack, pressure sensor 4 on net 3 is the strip setting, make pressure sensor 4 whether table tennis 3 is touched in sensing that can be fine on net 3, and net 3 adopts ball rack 31 to fix on the both sides lateral wall of base plate 21, but not fix on the lateral wall of 1 both sides of table tennis, can be fine avoid the table tennis to cause 3 vibrations of net when striking table tennis 1, greatly reduced normally hit the influence of pressure sensor 4 acquisition signal on the table tennis table 3.
And the pressure sensor 4 is used for detecting the pressure of the table tennis landing point, the pressure sensor 4 is arranged on the net 3, the pressure sensor 4 is arranged between the table board 1 and the table rack 2, and the pressure sensor 4 can select a common small pressure signal collector, such as QLW-13 small-space miniature force sensor of Shenzhen Qin Heyuan science and technology Limited company, which can well collect the pressure signal of table tennis landing point impact or net wiping.
Judge in the device will judge the result and transmit to the score device, after judging the device and gathering pressure signal, can be directly with in signal of telecommunication transmission to the score device, form instant score in the score device, the score device can adopt CPU or simple controller, CPU or controller can be very simple gather the processing to the sensor signal, this also is very simple technical content to the personnel in the field, can be very simple just can accomplish the data that the score device gathered pressure sensor 4 and collect processing and conversion, only need can carry out conversion processing to the signal of telecommunication, convert into digital signal, can embody can.
The scoring device forms instant score and demonstrates through real-time score display screen, the scoring device obtains the back that the signal of telecommunication converts, can obtain the digital signal of specific score, thereby transmit to real-time score display screen, show, and, the display screen is controlled through CPU or the controller among the scoring device, a technological means also commonly used, similar computer and TV set, carry out image display through CPU control display screen, non-simple conventional technical content, furthermore, the display screen can also install the voice broadcast ware, carry out synchronous voice broadcast.
A score judging method of an intelligent table tennis table system.
As an example, when the player a and the player B play a game, there are a service stage and a turn stage, and the scoring determination methods in the two stages are described in detail first.
A service stage:
if the table tennis is rubbed on the net 3 when serving, the strip pressure sensor 4 in the net 3 device is touched, if the table tennis is rubbed on the table board 1 of the opposite side after the table tennis is rubbed on the net, the table tennis is automatically judged as net rubbing, and the real-time score display screen displays and sends out the voice prompt of re-serving;
if the table tennis cannot fall on the opposite table board 1 after being used for net wiping, the error of serving the table tennis is indicated, and the other side is directly judged to score;
and (3) a turn stage:
after the ball serving is finished, after a plurality of rounds of hitting, if the last table tennis ball falls on the table board 1 on the side of one side, the opposite side is judged to score.
Namely:
in the process of serving in a match, a player A is a serving party, if the player A serves to wipe the net, a strip-shaped pressure sensor 4 in a net 3 device is touched, if a falling point exists on the table top 1 at the side of the player B after the ball is wiped, the net is automatically judged to be wiped at the moment, and a voice prompt of re-serving is displayed and sent out through a scoring device; if the ball fails to fall on the table board 1 at the side of the B player after being wiped by the net, the error of serving the ball is explained, and the B player of the opposite side is directly judged to score.
A and B match, A is the party of serving, half a table in front of A is the A table, the opposite side of the same reason is the B table, when A player starts serving, the player must contact the A table first and not contact the net 3 and then contact the B table for normal serving, after a plurality of rounds, if the last ball falls on one table, the party of serving is judged to score, that is, the last ball falls on the A table, the player B scores, if the last ball falls on the B table, the player A scores.
The judging device transmits the result to the scoring device to form an instant score which is displayed through the real-time score display screen, the international competition system is 11, when one party reaches 11 scores and leads the other party by 2 scores, the competition is finished, the integral device returns to zero, and the real-time score display screen displays the presented score; if the ratio of the two parties is 10:10, one person can still carry out ball exchange and serve according to the ping-pong rule until one party leads 2 points, and the game is finished, and the processing result is the same as the above.
Finally, the most important arrangement of the invention is to arrange the pressure sensors 4 between the table board 1 and the base plate 21 and on the ball net 3 respectively for judging the drop points of the table tennis, thereby realizing the optimal method for score judgment, and the pressure sensors 4 are arranged below the whole surface of the table board 1, if a player touches the table board 1 in the process of the game, the player can also be judged to have a violation, the ball is directly judged to be negative, because the player can not touch the table tennis table in the game rules.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
