Description

The invention relates to biotechnical systems and is intended for sports and technical training, can also be applied in medicine to restore human motor functions.

A device for controlling the motor functions of an athlete in the process of training is known, which includes a simulator with sensors of biomechanical characteristics, a computational node connected with each other and a recording device, a memory unit and a control panel.

The disadvantage of this device is the low efficiency of training due to the lack of motion estimates and movement correction of the athlete.

The closest to the proposed technical entity is a device for controlling the motor functions of an athlete in the process of training, containing a simulator with sensors of biomechanical characteristics, a computing unit and a recording device, a memory block, made in the form of threshold and reference values setting blocks, a control panel, corrective action block, signal conditioner with indication, relay blocks, decoder, register, switch, amplifiers.

The complexity of perceiving corrective information represented by this device due to low demonstration qualities does not allow to achieve high efficiency of training.

The aim of the invention is to increase the efficiency of learning.

The goal is achieved due to the fact that a known device for controlling the motor functions of an athlete in the process of training, comprising a serially connected control panel, a memory unit, a comparator, a recording unit, a corrective action unit, a simulator with sensors of biomechanical characteristics with an indication, the output of which is connected to the second input of the comparator, the second output of the corrective action block is connected to the second input of the simulator with sensors of biomechanical characteristics, in order to accelerate the learning To adapt the actions of the subject to the motion model, it contains serially connected video chart display unit and video record counter, the output of which is connected to the input of the test panel, the second output of which is connected to the first output of the video chart display unit, the second input of which is connected to the second output of the corrective actions block.

The drawing shows a block diagram of a device for training and monitoring an athlete's motor actions.

The device contains a video image display unit 1, for example, a Rainbow-2 film projector or a video recorder, a videogram counter 2, a control panel 3, a memory block 4, a comparator 5, a recording unit 6, a corrective action block 7, a counter 8 with sensors of biomechanical characteristics, for example, goniometers ( sensors of articular angles), accelerometers (acceleration sensors of movements of biotongs), strain gauges (sensors

5 support reactions) and sensors of electrical muscle activity.

The video display unit 1 is connected to a video counter 2, the output of which is connected to the remote control 3,

0 by the memory block 4, the first input of the comparator 5, the registering block 6, the block 7 of corrective actions, the simulator 9 with sensors of biomechanical characteristics with indication, the output of which is connected to the second input of the comparator 5, the second output of the block 7 of corrective actions, is connected to the block 1 videograms and the second input of the simulator 8 with sensors of biomechanical characteristics.

0 The device operates as follows.

A videogram, such as a kinogram, with the movement being studied, is set in a videogram display unit, e.g.

5 movie projector. The student looks at the video charts and analyzes them, highlighting the main reference movements and the addresses of their frames recorded by counter 2. Next, in block 4 of the memory from the remote control 3 of the control, the signals of logical 0 or 1 motion parameters are recorded for each video chart of interest. The control panel consists of triggers, at the outputs of which the learner switches

5 signals of logical 1 or O, which are supplied for recording in memory block 4. From the control panel, the learner, through a switch, sends an electrical signal (+ 5V) to the RAM (memory block 4) for

0 storing the generated codes at a specific address (frame). The control panel 3 is also used by the student to turn on and off the movie projector at the stage of viewing and encoding video frames. At the same time, up to four movement parameters, such as the position of the arms and the chog, are taken into account simultaneously. The right leg is bent - right leg left - the right hand is bent - right leg left hand is recorded respectively 1 - O - 1

- O. This completes the stage of forming a motion model.

During the training, the student, observing on the screen a figurative model of movement represented by the display unit of videograms 1, tries to reproduce most accurately his movement on a simulator 8 equipped with sensors of biomechanical characteristics that can be fixed at four points of the athlete's bioscript involved in performing a certain type of exercise . The output pulses of the sensors through the signal conditioner with indicators arrive at the second input of the comparator 5. At the same time, the signals from the 4th memory block also receive signals of the reference movements each time the videograms change to the first input of the comparator 5. When the signs of the measured parameters do not match with the reference characteristics, the comparator 5 outputs signals , read by the recording device in the form of errors for all monitored characteristics in each represented videogram. The recording unit 6 also records the time of the attempt.

Comparison signals, after reading by the registering unit 6, arrive at the corrective action unit 7, which, in case of discrepancy between the model and actual motion parameters, integrates specific electrical stimulating signals, which act on the executive devices of the simulator 8, correct the movements of the athlete by creating external strength conditions, which contributes to the efficiency of functioning locomotor mechanisms of the learner. In addition, the block 7 of corrective actions performs a light or sound signal if there is a mismatch between some parameter of the student’s movement and the reference one. The signals from the block 7 of corrective actions also go to the block 1 of the display of videograms,

which changes the rate at which they are displayed (down to zero) depending on the number of errors made.

The technical advantages of the proposed device, in comparison with the well-known, are the ability to automatically adjust the display unit of the videograms (film projector, video recorder) and the athlete on the simulator depending on the quality of the exercises copied by the athlete from the videograms, which allows for self-training and with high efficiency, creates the most comfortable conditions for error-free multiple copying of movements in various sports, improves the demonstration s quality of the device structure is simplified, which increases the efficiency of the motor and the learning improvement.
