Description

The invention relates to devices for training, in particular to simulators, and mainly concerns issues of training and improving human movements in sport, prosthetics, driving control, etc.

Devices are known consisting of load devices and kinematic chains reproducing the structure of the movement under study. In these simulators, the trainee is offered a tough training program. In general, they are used in the initial stages of training Gt and

The disadvantage is that there is a lack of information about the phases of movement and temporal parameters.

Also known are devices comprising a simulator, a task unit, motion detection sensors of the simulator, a comparison unit, an operator console, an action unit and an indicator. These devices are used in sports, for example, to control the pedaling mode, the movements of a gymnast, etc., in prosthetics to develop a symmetrical pitch, when learning how to control airplanes, working on machine tools, etc. In them, the trainee is presented with an operator task (the model of movement that he has to work out. The results of the movement are compared in the comparison block with the task and presented to the student by means of an indicator. In this connection, it is possible to accelerate the training and develop the movement in a number of cases in these systems are not limited to indication of the mismatch, but also produces an active effect on the body G3 and.

However, due to the fact that the movement program is discrete and represents an ideal performer, a sub-optimal skill is developed that often requires large energy expenditures.

Closest to the invention is a device comprising a simulator, a task unit, motion detection sensors of the simulator, a comparison unit, an operator console, an action unit, an indicator, and force sensors. It uses force sensors to assess the quality of the movement performed, and force information is fed to the indicator and is an additional tool to improve the technology. 5 However, as before, the student masters the integral portrait of the ideal operator. In addition, the resulting movement of a person is the result of the work of a complex multi-link chain (hands. The use of only output information for training does not accelerate learning, since the resulting movement can occur with a huge continent of combinations of movements of individual links. All this reduces the accuracy of the device, which impairs the quality of the workout. The purpose of the invention is to improve the accuracy of the device.

This goal is achieved by the fact that in a known device containing an operator console connected directly to the driver of the action signals and through the input of the training program to the first input of the comparator, the second input of which is connected through the first sensor unit to the simulation of real motion processes, and the output - with the shaper of the action signals and with the display unit, which through the second sensor unit is connected to the unit for imitation of real motion processes, sequentially injected the third block is introduced The sensors, the calculator of energy costs, the unit of human movement, the unit for setting critical training parameters and the generator of correction signals for the training program connected to the input unit for the training program and the impact signal generator, the outputs of the operator console are connected to the calculator energy. The expenses and the unit for modeling the movements of a person, which is connected to the second and third blocks of sensors, the calculator of energy costs is connected to the block of critical learning parameters and the second block of sensors. .

The drawing schematically shows the proposed device.

The device contains a training object 1, an operator console 2, a training program input unit 3, a driver of k impact signals, a real process simulation unit 5, a first sensor unit 6, a comparison unit 7, a second sensor unit 8, a third sensor unit 9, an indication unit 10, a unit 11 simulations of a person’s movements, a computer 12 of energy costs, a driver of 13 training program correction signals, a block 14 for setting critical training parameters.

The operator panel 2 is designed to control the operation of the device. Block 5 is the primary means with which professional skills and chance are fulfilled. With SiTOM, it can represent a system simulating a control in a specific process or a Sizject, or simply a kinematic Chain reflecting the dynamics of the explored movement (in sports, for example, a bicycle ergometer, a rower for rowing, etc.) With block 5, the direct blocker 6 is recalled (blocking the movements of the treasurer, which characterize the process of the student performing this task). it can be installed sensors of angular or linear accelerations, accelerometers, etc. Shaper k is designed to influence a person in order to teach him a given program. Impacts can be audible, tactile, etc., mainly to be perceived by the human body and contribute to a targeted correction of its movements depending on the type and sign of exposure. Blocks 8 and 9 record the basic motion parameters of human links required for estimating energy consumption. Energy consumption is determined by calculator 12, which is based on the construction of a so-called generalized phase trajectory. This device makes it easier than others to obtain information about the energy consumption on the basis of data on the parameters of displacements of the links constituting the kinematic chain that implements the motion. Blocks 11 and I are designed to detect the leading element of the movement that contributes most to the total energy consumption. The indicated construction of the system allows one to realize the simplest way for a student with such a MULTILATERATED 1 system as a human being. Due to the selection of the leading element, learning takes place only for this element, taking into account the task and minimum energy consumption. The next element is then determined by its

energy input, training on it, etc.

The device operates as follows.

From the console 2, the student is assigned a training program using block 3. Simultaneously, from the console 2, the calculator 12 and the block 11 are supplied with data on the main biomechanical constants of the organism, corresponding to a specific person. Upon presentation of the task, the learner begins training. The results of work, measured using block 6, are fed to one of the inputs of block 7, to the other input of which a signal is output from block 3. As a result, the output of block 7 produces a signal proportional to the mismatch between the specified motion program and the result of the student's work. This signal is fed to block 10 and to the driver to control the training process. At the same time, block 10 receives a signal from block B, which helps the student to reinforce the skill corresponding to the least effort. However, the process of learning with help. The described part of the system takes a long time and is of poor quality, since the skill developed does not correspond to optimal working conditions, but is oriented towards a certain model of an ideal worker. The remaining blocks serve to eliminate this deficiency in the object. The calculator 12 determines the energy and motion of the movement and, with the help of block 1 1 and block 1 k, identifies the leading elements of motion of the driving element of the multi-link chain, which has the greatest impact on energy consumption. With the help of the block AND, the impact correction program is set by the former 13,

so learning by minimizing the energy input from this element. Upon reaching the minimum, the next leading element is determined, and so on. As a result, after completing the training, the person performs a complex movement with a minimum of energy consumption.

I AKIM way, the use of the proposed invention allows in comparison with the prototype to improve the quality and individualize the learning process, as well as reduce the time required for training which improves the accuracy of the learning process.
