The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1-4, the present invention provides a technical solution:
an intelligent table tennis table system, comprising:
the actual appraising device and the real-time score display screen;
the actual appraising device is divided into a appraising device and a scoring device, wherein the appraising device comprises:
the ball table comprises a ball table surface 1 and a ball table frame 2, wherein the ball table surface 1 is paved on the upper surface of the ball table frame 2, the ball 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 ball table surface 1 and the base plate 21 are detachably arranged;
in the setting process of the ball table top 1, the base plate 21 which is arranged in a separated mode can ensure that the pressure sensor 4 between the ball table top 1 can be more convenient to install and maintain and use, in addition, the mode of directly installing the pressure sensor 4 on the surface of the ball table top 1 is not adopted, abnormal ejection caused by the fact that a table tennis ball directly falls on the pressure sensor 4 can be well avoided, in this way, the ball table top 1 is only required to be set to be a thin plate, the thickness is set to be 0.5-2mm, normal ejection after the table tennis ball impacts the ball table top 1 is not affected, and the pressure sensor 4 below can be well enabled to collect a falling point to generate a pressure signal.
The pressure sensors 4 between the ball table top 1 and the ball table frame 2 are distributed in a dot shape, and the distance between the adjacent pressure sensors 4 distributed in the dot shape is smaller than the diameter of the table tennis, so that dead angles, where pressure cannot be collected, are avoided after the table tennis falls on the ball table top 1, and the collection accuracy is very convenient.
The net 3, it is used for equally dividing into the ball mesa 1 about two halves, net 3 passes through net rack 31 fixed connection on the lateral wall of ball bench 2 both sides, pressure sensor 4 on the net 3 is the strip setting, make pressure sensor 4 sense whether the table tennis touches net 3 on net 3 fine, and net 3 adopts net rack 31 to fix on the lateral wall of both sides of base plate 21, and not fix on the lateral wall of ball mesa 1 both sides, can be fine avoid the table tennis to arouse net 3 vibrations when striking ball mesa 1, the influence of pressure sensor 4 collection signal on the normal hitting table tennis ball net 3 has greatly reduced.
And the pressure sensor 4 is used for detecting the pressure of the table tennis drop point, the ball net 3 is provided with the pressure sensor 4, the pressure sensor 4 is arranged between the ball table surface 1 and the ball table frame 2, the pressure sensor 4 can select a common small pressure signal collector, for example, a QLW-13 small-space miniature force sensor of Shenzhen Qin hybrid science and technology Co., ltd, and can well collect the pressure signal of the table tennis drop point impact or the net wiping.
The judgment device transmits the judgment result to the scoring device, after the judgment device collects the pressure signal, the electric signal can be directly transmitted to the scoring device, instant score is formed in the scoring device, the scoring device can adopt a CPU or a simple controller, the CPU or the controller can collect and process the sensor signal very simply, the technical content is very simple for the person in the art, the collection, processing and conversion of the data collected by the pressure sensor 4 by the scoring device can be completed very simply, and the data can be reflected only by converting the electric signal into a digital signal.
The scoring device forms instant score and displays the instant score through the real-time score display screen, the scoring device obtains the electric signal to convert the electric signal, and then the digital signal of the specific score can be obtained and transmitted to the real-time score display screen to be displayed, the display screen is controlled by a CPU or a controller in the scoring device, and the scoring device is also a common technical means, like a computer and a television, and the display screen is controlled by the CPU to display images, so that the scoring device has no simple conventional technical content, and in addition, the display screen can be provided with a voice broadcasting device to synchronously broadcast voice.
An intelligent table tennis table system score judging method.
As an example, when a player and a player play a game, there are a serve stage and a round stage, and the score determination methods of the two stages are first described in detail.
A service stage:
if the table tennis is wiped on the net 3 during playing, the strip-shaped pressure sensor 4 in the net 3 device is touched, and if a landing point exists on the opposite ball table surface 1 after the table tennis is wiped, the table tennis is automatically judged to be wiped, and a voice prompt of playing the ball again is displayed through a real-time score display screen;
if the table tennis cannot fall on the opposite table surface 1 after the table tennis is wiped, the fault of serving the ball is indicated, and the score of the opposite party is directly judged;
the round stage:
after the ball is delivered, after a plurality of rounds of hitting, if the last table tennis ball falls on the table surface 1 on the side of one of the table tennis balls, the score of the opposite side is determined.
Namely:
in the playing step, if the player A is a pitching party, if the player A is involved in pitching and rubbing, the strip-shaped pressure sensor 4 in the net 3 device is triggered, if a landing point exists on the table surface 1 on the side where the player B is located after the ball is rubbed, the player A is automatically judged to be rubbing, and a voice prompt for restarting the pitching is displayed and sent through the scoring device; if the ball cannot fall to the ball table surface 1 on the side of the player B after net rubbing, the ball serving error is indicated, and the score of the player B is directly judged.
A and B play a match, A is a serving party, namely a half of the tables in front of the A face are A tables, and the same thing is that the B tables are opposite, when the A player starts serving, the A tables are contacted with the A tables firstly and are not contacted with the net 3, then the B tables are contacted with the A tables for normal serving, after a plurality of rounds, if the last ball falls on one of the tables, the opposite party is judged to be scored, that is, the last ball falls on the A tables, the B player is scored, and if the last ball falls on the B tables, the A player is scored.
The judgment device transmits the result to the scoring device to form instant score which is presented through the real-time score display screen, the international competition is 11 scores, when one party reaches 11 scores and leads the other party by 2 scores, the game is ended, the integrating device returns to zero and the real-time score display screen presents the score display; if the ratio of the two parties is 10:10, a person and a ball are still exchanged according to the table tennis rule until one party is led by 2 minutes and the game is ended, and the processing result is the same.
Finally, the most important arrangement of the invention is that the pressure sensor 4 is respectively arranged between the table top 1 and the base plate 21 and on the net 3 to judge the falling point of the table tennis so as to realize the optimal method of scoring judgment, and the pressure sensor 4 is arranged below the whole surface of the table top 1, if a player touches the table top 1 during the competition, the player can judge the foul, and the ball is judged to be negative directly, because the player cannot touch the table tennis table in the competition rules.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
