Description

one

The invention relates to sports simulators and is intended to measure and record the level of tactical fitness of volleyball players. .

A device for evaluating tactical preparedness of volleyball players is known, comprising a switching unit connected to the light indicators 1.

The disadvantages of the known device are the presence of a manual set of game combinations, the lack of opportunities for creating conditions simulating typical game situations, the inability to automatically measure and record the level of tactical readiness of volleyball players.

The purpose of the invention is to increase the quality of the evaluation of the tactical readiness of volleyball players.

The goal is achieved by the fact that the device for evaluating tactical readiness of volleyball players, containing a switching unit connected to the light indicators, has a task setting unit for playing combinations, a transmission direction estimator unit, a time measurement unit, a distribution unit

and a digital printing unit, with the first output of the task setting block of the game combinations connected to the input of the switching unit, the second third and fourth outputs of the task setting block of the game combinations are connected respectively. with the inputs of the transmission direction estimation unit, the time measurement unit and the distribution unit, and the output of the transmission direction evaluation unit, and the output of the time measurement unit

, Q are connected to the inputs of the distribution unit, the output of which is connected to the digitizer.

FIG. 1 shows a block diagram of a device for evaluating the tactical readiness of volleyball players; in fig. 2 shows the layout of the sensors and

15 light bulbs on the volleyball court.

The device comprises a game combinations task unit 1, the first output of which is connected to the input of the switching unit 2 connected to the light indicators 3. The second, third and fourth outputs of the game combinations task unit 1 are connected respectively to the inputs of the transmission direction estimator 4 having three photoelectric sensors 5-7, a time measurement unit 8 having contact sensors 9 and 10 and a distribution unit 11, and the output of the transmission direction estimator 4 and the output of time measurement unit 8 are connected to the input MI distribution unit 11, the output of which is connected to the digital printing unit 12. The device operates as follows. Upon command from the control panel, a catapult is turned on, which throws the ball in the direction of the volleyball net to the opposite side before meeting the reflector board. In the center of the volleyball court there is a volleyball binder, on whose fingers there is a sensor 9 (Fig. 2), and on the shin of his leg a sensor 10. After touching the screen with a reflector shield, one of the three light bulbs turns on (L4, Ld, Le ) located on the same side of the pitch as the volleyball player. After a certain time, which can vary from 0.1 to 1, with a resolution of 0.1 s, one of the three light bulbs (L ,, L2, Lz) turns on, which imitates the position of the blocking player located on the opposite side of the net relative to the volleyball player binder From the moment one of the three light bulbs is turned on (L, Lz, L), using the time measurement unit 8, the measurement of the decision time starts, and the clock ends when the sensor 10 triggered on the bottom of the volleyball player connects. The same sensor 10 records the beginning of the measurement of motor time by a second stopwatch. The flying meter crosses the plane of the photoelectric sensor 6, which gives a signal to activate the third electronic stopwatch. After touching the sensor 9 on the fingers of the volleyball player's binder, both stopwatches stop and the engine and critical time are displayed on the board. The decision in response to the proposed coded program — the volleyball player’s task is implemented through a second transmission into one of the photoelectric sensors 5–7 installed above the volleyball net. The transmission, performed by the volleyball player, is analyzed and evaluated by the transmission direction estimation unit 4. After measuring the time parameters and estimating the transmission direction, the information remains recorded in the time measurement units and the evaluation of the transmission direction. The gaming combinations task unit 1 generates a signal permitting the transfer of the recorded information through the distribution unit 11 to the block 12. The distribution unit serves to match the signals by level, duration and polarity, as well as to establish the order of receipt of information to the block 12, which records the game number combinations, timing and estimation of the direction of transmission. M h after passing the floor. from sensors 5-7, it enters the catapult magazine and is ejected again. A start-up signal is again formed, which initializes all the nodes of the circuit of the proposed device. The task unit 1 forms a new game combination, and the switch unit 2 includes two electric bulbs of the existing ones. In the manual mode, using the button switch, the trainer selects one of the nine game combinations and, using the Start and Reset buttons, can repeat this combination repeatedly. Evaluation of motor actions is performed on a four-ball scale. Thus, the proposed device allows you to reliably automate the conditions of typical models of game situations and automatically measure and record information parameters: an assessment of the correctness of the execution of the task program, decision time, motor time and critical decision time. The economic effect from the introduction of the proposed invention is to reduce the cost of training high-class volleyball players. An apparatus for evaluating the tactical readiness of volleyball players, comprising a switching unit connected to light indicators, characterized in that, in order to improve the quality of the assessment, it has a task setting unit, a game direction measurement unit, a time measurement unit, a unit distribution and digital printing unit, the first output of the task setting block of the game combinations connected to the input of the switching unit, the second, third and fourth outputs of the task setting block of the game combinations with respectively, with the inputs of the transmission direction estimator, the time measurement unit and the distribution unit, and the output of the transmission direction estimator and the output of the time measurement unit are connected to the inputs of the distribution unit, the output of which is connected to the digitizer.
