Description

The invention relates to adaptive simulators and can be used as a simulator for control system operators. An adaptive simulator is known that contains an information board associated with its input to the first output of the comparison unit, the second output of which is connected to one input of the evaluation unit connected to the first input of the control unit, the second input of which is connected to the output of the blocking node 1. A disadvantage of the known simulator is the low efficiency of the simulator. The purpose of the invention is to increase the efficiency of the simulator. The goal is achieved by the fact that an adaptive simulator containing an information board associated with its input to the first output of the comparison unit, the second output connected to one input of the evaluation unit connected to the pervill input of the control unit, the second input connected to the output of the node blocking; it has a block of physiological influences on the operator, a node for controlling the rhythm of the operations performed, a program block and a block for measuring the bioparameters of the operator, while this is the output of the block of measuring the bioparameters of the operator with the inputs of the comparison unit and the blocking node, the output of the software unit is connected to the information input of the comparison unit and the control input of the evaluation unit, and the output of the control unit is connected to the input of the physiological effects unit onetJaTopa and the input of the rhythm control unit of the operations performed. Figure 1 presents the block diagram of the proposed simulator; Fig. 2 is a diagram for explaining the operation of the device; on fig.Z - timing charts of the device at different points of the simulator. The adaptive simulator (Fig. 1) contains an operator’s biological parameter sensor 1, a biological operator’s meter 2, a comparison unit 3, a software unit 4, an assessment unit 5, a control unit 6, a operator’s physiological effects unit 7, an information board 8, a blockage block 9, the rhythm sensor 10, the corrector 11 sets the rhythm of the operations to be performed, the block 12 sets the rhythm of the performed operations, the information input 13 of the local comparison 3, the control input 14 of the evaluation unit 5. The node of the regulation of the rhythm of the performed operations has

Atchik 10 rhythm, corrector 11 specify the rhythm of the operations performed and block 12 set the rhythm of the operations performed.

The simulator is based on the implementation of physical loads performed by the operator on velor gauges, treadmills, etc., i.e. on such simulators, where it is possible to electrically influence the executive body (on a bicycle ergometer - creating a braking moment, on a treadmill - adjusting the speed or creating a brake of the regost moment).

The program for changing the physical activity of the operator can be set according to any biological parameter (heart rate, oxygen consumption, pressure, force developed by muscles, etc.). In the process of training, the program parameter is changed in accordance with the wishes of the coach, doctor. After switching on, the adaptive simulator works as follows

In program block 4, a program is introduced to change the operator's physical load during the training. Program is set by change.

biological parameter, such as heart rate (HR) y in time.

From the output of program block 4 to block 3 of comparison and block 5 of evaluation, information is received on the current program value of the heart rate. At the other input of the unit 3, the comparison is received through the sensor 1 and the meter 2 is the current actual heart rate of the operator. From the output of block 3, the difference between the current program and actual values of the heart rate is fed to the input of the display 8 and the other input of the evaluation unit 5, in which the error of the biological parameter value is estimated, and the corrected value is fed to the input of the control block b. The control unit serves to generate the control signals to the physiological effects unit 7 and to the rhythm setting unit 12. From the output of the rhythm setting unit 12, the input to the rhythm setting corrector 11 receives information about the program rhythm of the operation. The other input of the corrector 11 from the sensor 10 receives information about the current rhythm. The corrected rhythm in the form of sound signals is reported to the operator. In case the heart rate reaches a critical value from the output of the blocking node, a command is issued that turns off the block

control from the actuator.

Let us consider in more detail the work of individual blocks.

When the meter 2 (fig.Z)

biological parameter from the output of the sensor 1 electrocardiogram (EX) is fed to its input. In meter 2, the signal is then amplified. Amplified signal, pass filter,

where the filtering takes place at the higher and lower frequencies, is fed to the input of the square pulse generator. In this former, the R-wave is extracted from the ECS and the corresponding rectangular pulse is formed. Rectangular pulses (or R-R intervals) are fed to the input of a pulse duration transducer to a pulse frequency, s

the output of which is a bundle of rectangular pulses (their number is equal to the instantaneous pulse frequency) is fed to the input of the unit 3 of comparison.

Comparison unit 3 (FIG. 3) operates as follows.

A burst of pulses, corresponding to the current given pulse N j, is fed to the counting input of the counter, where it is memorized. Burst

corresponding to the current instantaneous pulse N, is fed to the counting input of another counter, where it is memorized. The last pulse of the pack starts the generator, from the output of which the pulses go to the inputs of the counters. If the values of the counters are equal, they zero at the same time and a inhibitory signal arrives at the other input of the generator and

the generator stops. In the case of N 3 N, the number of pulses dN equal to N appears at the output of the block, - W-r. If N3 NT, then the value of dYy appears. After zeroing

both counters, the generator stops. Thus, from the output of block 3 to the input of block 5 enters LA — the difference between the values of N and the corresponding sign. Program block 4 operates as follows.

From the keypad, the value of the parameter to be set (time, HR value) enters through the switch to the memory circuit. At the same time, some of the information is fed to the input of an arithmetic unit, the operation of which is explained in Fig.2. Let it be necessary to record a change in pulse along the line A, b. In memory

t and 11, F are entered,

the arithmetic unit is the value of F (i, F, tn. Then, in the arithmetic unit, the operation FO-F AF is performed, the necessary change

the programmed heart rate (for the considered example) during time t (s). in the future, the increase in the program value and comparison of the program and current values of the pulse is considered by theBawT after 1 s. Dividing dP by t, (we obtain the U-change of the program value in 1 s. During the operation, the following operations are performed: F, (1 s after the start (2 s after the start.) F. (after p s after the start) . Every second at the output of block 4 there is a burst of pulses corresponding to the increment of the HR value - U and the current program value N, Thus, an operation is performed in the arithmetic unit and the value d is written to the memory. the arithmetic unit receives the value F and the operation (F + D) is performed. All programmatic changes in the heart rate are fulfilled with perfection. The corrector and the rhythm block work as follows: The frequencies coming from the sensor 1 and the block 12 for setting the rhythm go to the transform inputs, from which voltage and uj are sent to the subtracting amplifier, respectively. amplifier & U U -, - U is fed to the input of the summing force of the bodies, to the other input of which the value U is fed, the sum U + AU is fed to another converter. From the output of this converter, the frequency is fed to the input of the generator, where the pulses are filled with a tone signal, is fed to the speaker. Sensor 1 (in the case of the example of heart rate, these are electrodes, laid on any standard lead of the operator’s electrocardiogram. Sensor 10 can be a magnetic contact for a bicycle ergometer that operates 1 time per pedal rotation; for a treadmill, it is a shock-type sensor that operates at the moment of contact soles with a simulator belt; for a rowing simulator, an end sensor, triggered in one of the extreme positions. For a bicycle ergometer (with magnetic braking), block 6 is a controlled power source of a magnetic brake, for running The track when braking is similar to a bicycle ergometer as well as when the track is moving the block b is the engine power source. Using the proposed simulator increases the efficiency of the simulator, as it allows you to control the exercise dose received by the operator during training, adjust the program in accordance with the physiological state operator and turn off the machine in case of exceeding the load of the established norms.
