Description

(54) DEVICE FOR AUTOMATED CONTROL OF PARAMETERS OF COMPLEX OBJECTS The invention relates to automation and can be used to create automated control devices for control systems for complex objects including an operator (person). According to the main auth. No. 284436, a device for automated control of complex object parameters is known, comprising a program input unit, a decoder, a control unit, a processing unit, a parameter control measuring unit, a printing unit, a control and display console, a switching unit, a remote control operator’s control unit, manual controls. The control unit, the tracking unit of the emergency parameters and the unit for determining the errors of the operator of the control object, the outputs of which are connected to the control unit, the measuring unit and control parameters and manual controls, and output - automatic control unit start input. The quality and reliability of information-measuring and control systems that require an operator in their work depends on its physiological state. This fact is of particular importance in the case of work for a long time under adverse environmental conditions (elevated temperature, pressure, humidity, the effects of static electricity, etc.), if necessary, the operator will quickly execute complex and responsible commands. Automatic monitoring of the physiological condition of the operator can be carried out, for example, by analyzing the electrical conductivity of the muscles of the heart fl. The instability of the electrical conductivity of the muscles of the heart, as a rule, is manifested by the appearance of extrasystoles (electrocardio pulses of negative polarity), which in the normal state of the cardiac muscle of the operator do not practically occur. If extrasystoles occur quite often, for example, several single extrasystoles over 16 cycles of contraction of the heart train, or especially when several extrasystoses, for example 4, follow one another, then there is a danger of an adverse deterioration in the physiological state of the operator and, as a result, a decrease his performance, attentiveness, reaction, etc.

The purpose of the invention is to expand the field of application of the device, i.e. . the creation of a device for the automated control of the parameters of complex objects with the system of automatic tracking of the physiological-CMI state of the operator. I

This goal is achieved by the fact that a device for physiologically controlling sensors of physiological parameters, a parameter selector a static filtering unit for signals into a pulse action block, whose outputs are connected to a second input of a sensor of physiological parameters and, are entered into a device for automated control of complex objects. the second input of the parameter selector, the control input connected to the third output of the decoder, the control input of the statistical signal filtering unit are connected to the output of the control unit, the second output is connected to the fourth input of the control and display console and the ninth input of the control unit, and the third output is to the fourth the input of the processing unit, the statistical signal filtering unit contains the first, second and third pulse counters connected in series, the outputs of which are connected to the first inputs of the first, second and retego element and the second inputs of which are connected to the fourth output of the pulse counter, and the outputs - to the inputs of OR elements, wherein the third pulse counter output is connected to the input of the threshold element.

Figure 1 shows the block diagram of the device, figure 2 - block diagram of the statistical filtering of signals.

The device for automated control of parameters of complex objects (FIG. 1) contains a program input block 1, a decoder 2, a control block 3, a processing block 4, a parameter measuring and control block 5, a switching block 6, a print block 7, a control and display console 8 the remote control 9 of the operator of the control object, the operator 10 of the control object, the operator 11 of the control device, the sensors are the primary transducers of the control object 12, the block 13 for tracking the emergency parameters, the manual control organs 14, the block 15 for determining the errors of the operator of the object trolley bus, the block 16 of physiological parameter sensors, selector 17 parameters, statistical filtering unit 18 signals and the impulse of unit 19. impact.

Block 18 statistical filtering of signals contains (figure 2). The first 20, second 21, third 22 and fourth 23 counters, pulses, the first

24, the second 25 and the third 26 elements And the element OR 27 and the threshold element 28.

The device works as follows.

The operator 10, performing manual operations by the commands displayed on the remote control 9, acts, if necessary, on the automatic start circuit of unit 3. The operator 11 acts on the remote control 8 and, if necessary, also on the automatic start circuit of unit 3. To monitor the physiological state of the operator 10 The signals from block 1.6, fixed on the body of the operator 10, through the selector 17 are fed to the two inputs of block 18. These signals are two sequences of pulses: POLO-UTEL, corresponding to the number of contractions of the heart muscle, and ri0-negative, corresponding extrasystoles. Using successively connected counters 20, 21 and 22, the number of positive pulses is determined and, through element 28, controlled from the output of block 3, information about the frequency of contractions of muscle is fed to the input of block 4, in the case of disconnection of the frequency of muscle contractions from normal the signal from the output of block 4 is fed to the input of block 3, which

0 switches the operation of the entire system to the automatic control mode. The counter 23 counts four pulses of negative polarity, and the counters 20, 21 and 22 respectively.

5 four, sixteen or one hundred twenty-eight cycles of cardiac muscle contraction, in case of a dangerous occurrence, for reliable functioning of the four ecstrasystoles system

0 (counter 23). during the four contractions of the cardiac muscle (counter 20) resets the element I 24 and the signal from its output starts block 19, from the first output of which a short-term electric charge arrives at

5 block 16, and the signal from the second output at this moment turns off the selector 17. At the same time, the element OR 27 is triggered, the launch of the automatic start control circuit of block 3 and the translation

0 system in automatic control mode, and remote control 8. Counters 21, 22 and 23, together with elements And 25 and 26, account for the occurrence of four extrasystoles during sixteen or one hundred

5 twenty eight contractions of the heart muscle.

In the case of the occurrence of four extrasystoles for-time sixteen contractions of the heart muscle. the pulses from the outputs of the counter 21 and 23 are fed to the inputs

0 element 25 or from the outputs of counters 22 and 23 to the inputs of element I 26, if four extrasystoles occur during a hundred and twenty-eight periods of contraction of the cardiac mystus. Signal with you. moves of elements And 25, 26 enters through the element OR 27 to the input of block 3 and to the console 8.. Thus, the transition to the automatic control mode is carried out in a timely manner and a signal is displayed about an undesirable change in the physiological state of the operator. Using the proposed invention allows to increase the reliability of the operation of automated control systems for the parameters of complex objects, the probability of their trouble-free operation during the year is increased by 15%.
