Description

The invention relates to the field of devices and can be used to test and train the psychomotor activity of athletes and specialists of specific professional fields.

There is a known method of testing the human reaction and a device for its realization comprising a signaler (speech generator), switches and a time recorder (see European Patent No. 0513419, A 61 B 5/16, P> K HCM, 7-05-94). .

The specified technical solution performs very few functions, i.e. it only measures the reaction time from the command run until the key is pressed.

The response time to light pulse t is known. y. psychomotor response rate measuring device Random R-test, consisting of a horizontal support plane, an irritation system, a control and measurement unit and a control system in which a human eye notices a light irritant stops the timer by pressing the right or left hand button. light irritant. The rate, mean, and standard deviation of the psychomotor response are then calculated by plotting the best and worst response times. (see Finnish catalog Nevvtest 1995.).

The given prototype is not functional as it can only measure the psychomotor response, its mean, standard deviations, throwing the best and worst response times. This device does not analyze the trajectory of motion, as well as the temporal dependence of force, the coordinated movement of two arms or legs on an independent or common target.

The object of the invention is to extend the functional capabilities

The object is achieved by the human motion dynamometer analyzer consisting of a horizontal support plane-based irritation system, a control and measurement unit and a control system consisting of a standard display and keyboard computer with a control and measurement unit and a control and measurement unit. the measuring system, the control system consists of two identical handles (pedals) freely placed on a horizontal plane, respectively for the right and the left hand (feet), connected to the force measuring mechanisms consisting of tensile sensors and through the force measuring units connected to the control and measuring unit gauging mechanisms consisting of motion transformation to a reduced gauge zone and through coordinate gauges connected to a control and gauge unit and force generation and gearing mechanisms connected to a gauge and gauge unit.

Fig. 1 is a block diagram of the device.

The analyzer consists of an irritation system 1 consisting of a standard computer 2 with a display 3 and a keypad 4 with a control and measurement unit 5 and an installed control and measurement program, the control system 6 comprising two identical handles (pedals) 7, respectively for the right arm and for the arm (legs) connected to the force measuring mechanisms 8 consisting of tensile sensors 9 and via force measuring units 10 connected to the control and measuring unit 5, coordinate measuring mechanisms 11 consisting of motion transforming into reduced measuring units 12 and through the coordinate measuring units 13 connected to the control and measuring unit 5 and the force forming and control mechanisms 14 connected to the control and measuring unit 5.

The analyzer operates in three modes: right hand (or foot) motion measurement training mode, left hand (or foot) motion measurement / training mode, or both hand (or foot) motion measurement / training mode

Right hand (or foot) motion measurement - training begins by pressing the handle (pedal) button 7 which forms a low logic level and is converted to the appropriate code by the software installed on the control and measurement unit 5. The program installed on the computer on the display 3 generates an image of the programmed gutter, position start area, programmed size and color target, as well as programmed sized handles (pedals) of resistance to movement by means of the control unit 5 and force generation and control mechanisms 14. The target image may appear in a fixed location or move at programmed speed and direction. The program may also program the appearance of misleading targets. After the target appears in the viewer 3, the software installed on the computer 2 measures the time until the hand trajectory from the start area reaches the target image area and stores in memory the handle (pedal) 7 trajectory (x and y coordinate points array) with the help of measuring unit 5. Upon reaching the target target in the viewer 3, the movement time of the handle (pedal) 7, the trajectory of the force applied to the handle (pedal) 7, measured by the force measuring mechanism 8 and the control and measuring unit, are recorded.

Measurement-training of left hand or foot movement is done analogously, only work with left hand or foot, respectively, with left hand handle 7 or left foot pedal.

Measuring and displaying both hands or feet in motion-training mode is analogous only to working with the right and left hands (feet) together. The monitor captures images of the starting area and targets for each arm (leg). The program may be programmed to use a common target.

Compared to the prototype, the new set of constructive elements significantly extends the analyzer's functional capabilities, as it allows to determine the human psychomotor response time in milliseconds, maximum speed V max (cm./s), motion accuracy, distance S (cm.). All of this can be accomplished by varying the color geometry of the target geometry of the resistance force. Analyzer can be used to analyze and draw conclusions about the human psychomotor state. This is very important when testing athletes, specialists in specific disciplines, researching physical activity, moments of weakening or increasing psychomotor response, such as children - adults, morning - evening, women using alcohol or other psychotropic substances and so on.
