Description

The simulator for evaluating the effectiveness of the training process in table tennis belongs to the field of sports, in particular, it is designed to train reaction speed and coordination of movement when playing tennis, and provides high performance in this sport at competitions.

Close to the proposed invention is a device for assessing and training anticipation of goalkeepers in football and hockey [RF Patent No. 67457], containing an electronic stopwatch with remote control, two light indicators with manual switches and an electronic stopwatch switch, characterized in that it additionally contains a radio transmitter, connected to the switch, a radio receiver with a relay included in the control circuit of the electronic stopwatch and performing the functions of its switch, as well as a registration unit, and the radio transmitter and switch with a button are placed in a metal case with a device for rigidly fixing it to the field. Common to the proposed invention are: a control unit, inside of which there is a stopwatch, a radio receiver, a radio transmitter, a power supply, and two light indications.

The disadvantage of this patent is the presence of manual toggle switches, which have a significant error in operation and low speed;

The closest (prototype) of the proposed invention is a device for assessing and training prediction in volleyball [RF Patent No. 101639], characterized by the fact that it contains a cuff fixed to the wrist and a remote control that includes a block of volleyball court zones and a measuring block, a block of volleyball zones the site contains light indicators of zones with switches, a battery and a radio receiver with a relay, a measuring unit contains an electric stopwatch, two light indicators with the inscriptions “Guess”, “Guess wrong” with switches, a display of the percentage of guessed zones of flight and ball falling and an average time display predicting the zone of the ball falling with switches, the cuff is made with a radio transmitter and its activation contact located on the palm part of the cuff.

The disadvantages of this device are:

- the presence of a cuff on the player's hand and contact on his palm, which during the game can move as a result of hitting the ball and disconnect contact with the remote control and turn off the device;

- mechanical toggle switches for determining the reaction time of the flight of the ball, determining the zone of the ball falling, determining the average reaction time of the trained player have low speed and are inconvenient to work with.

The objective of the invention is:

- control of the trainee's reaction time;

- control of information about the time of guessing the zones of the ball falling;

- control of information about the percentage of guessed zones;

- the possibility of making appropriate adjustments to the training process;

- analysis of digital information and the development of tactics for a more effective game.

The technical result from the application of the proposed invention is to increase the effectiveness of the training process in table tennis after long training with this device and the corresponding analysis, the conclusions of the player's work from the coach.

The technical result is achieved by the fact that the simulator consists of a table divided into four zones, the main and additional control panels, on the panel of each control panel there are five touch switches that record the reaction time of the trainee and the zone of the ball falling on the tennis table, a power source is located in the racket handle with a radio transmitter, on the working surface of the tennis racket there are conductive tires with spikes, and the outside of the ball is covered with conductive material.

FIG. 1 shows a general view of a game of table tennis. Table tennis table 1 is in the center. The left half of the table is divided into 4 zones. On the left and right of the table tennis table are the players with rackets 2. On the sides of the table tennis table, there are the trainee and the coach (understudy) on the right and left.

FIG. 2 shows a racket 2, which consists of a working surface 3 and a handle 4. There is a ball 5 with a conductive surface 6. On the handle 4 of the racket 2 there is a switch button 7 of a radio transmitter 8 with a power source 9, On the working surface 3 of the racket 2 there are tires 10, which voltage is applied to the spikes 11.

FIG. 3 shows the main 12 and additional 13 consoles. On the panel of the main control panel 12 on the left there is an indication 14 of the stopwatch, which is located inside the panel 12 and in Fig. 3 also does not show four touch switches 15, 16, 17, 18. corresponding to four zones, and the fifth switch 19, if the ball 5 flies outside the tennis table 1.

On the right side of the control panel 12 there is an indication 20 for predicting the zone of the ball falling 5. On the main panel there is also a power button 21 and a lamp 22 to turn on the control panel 12. The additional control panel 13 has five touch switches 23, 24, 25, 26, 27. Inside the main control panel control 12 placed a power supply 28, a stopwatch 29, an arithmetic device 30 showing the average reaction time of the trainee and the average percentage of predicting the zones of the ball 5.

The radio receiver 31, the power supply 28, the stopwatch 29, the arithmetic device 30 are located inside the console 12 and in FIG. 3 are not shown.

The main control panel 12 and the additional control panel 13 are connected by cable 32. On the control panel 12, the trainee presses the button 21 to turn on the power from the power source 28 and the lamp 22 lights up. The player on the racket 2, with the button 7, supplies voltage to the radio transmitter 8 from the power source 9. In this case, voltage is supplied to the working surface 3 of racket 2. Voltage is applied to spikes 11 of racket 2 in such a way that when racket 2 hits ball 5, ball 5 having conductive coating 6 closes the contacts of bus 10 and turns on radio transmitter 8, which sends a radio pulse. The impulse of the radio transmitter 8, located in the handle 4 of the racket 2, is carried out only at the moment the ball 5 touches the racket 2

On the remote control 12, as a result of a short pulse of the radio transmitter 8, the stopwatch 29 is turned on. After hitting the ball 5 with the racket 2, the ball 5 flies to the opposite side of the table tennis table 1. In the remote control 12, the stopwatch 29 is turned on, the information of which is sent to the display 14 and the trained player, sitting at the remote control 12, at this time must press one of the touch switches 15, 16, 17, 18,19, corresponding to the ball drop zone 5 on the table tennis table 1 on the remote control 12 and stop the stopwatch 29.

Due to the short flight time of the ball 5 on the console 12, five touch switches 15, 16, 17, 18, 19 are used for the trained player and stop the stopwatch 29. The four touch switches 15, 16, 17, 18 correspond to the four zones of the ball 5 falling on the table table 1, and the fifth switch 19 is necessary if the ball 5 flies out of the table 1. Five more similar touch switches 23, 24, 25, 26, 27 are available on the additional console 13. The coach (understudy) sitting at the additional console 13 sees into which of the zones the ball 5 fell and presses the corresponding switch 23, 24, 25, 26, 27.

Inside the console 12, the stopwatch 29 records the reaction time of the trainee and the information is displayed on display 14, which is located on the console 12 on the left. Digital indication 20 is located on the remote control 12 on the right and shows the percentage of guessing the zone of the fall of the ball 5.

The information of the coach is compared with the information of the trainee and is transmitted to the digital indication 20 for guessing the zone of the fall of the ball 5.

This information is constantly updated during the game.

Thus, the impulse of the transmitter 8 located in the handle 4 of the racket 2 is received by the receiver located in the control panel 12, the stopwatch is turned on, which is stopped by pressing the corresponding sensor button 15-19 of the trainee. As a result, the stopwatch stops and records the trainee's reaction time. This reaction time of the trainee is displayed on display 14. At this time, the coach sees in which of the zones on the table the ball fell, presses the corresponding touch button 23-27 on the additional panel 13. Information from the coach and the trainee is compared, analyzed and displayed 20.

Sequential interaction of all structural elements of the simulator during repeated work of the trainee, followed by discussion and analysis of the results, allow to evaluate the effectiveness of the training process in table tennis.
