for connecting 1 sensors, in this case, in general, 1 1. We restrict ourselves to considering the simpler case when 1 l, j ... l, where 1 is the maximum possible number of sensors, which characterizes the change of a parameter during the starting processes of a power unit. Then the number of blocks is 1 n P / 1. The state of comparators 2 at any moment of time can be characterized by a code of 1 and 1 bits, which we call the parametric word, since it reflects the characteristic points of change of the parameter depending on the number of the sensor. When the comparators operate, both normally open and normally closed contacts or potential circuits can be used. The system can accept both direct and reverse logic. We assume that if the start sensor or the protection sensor is a normally open contact or corresponds to zero voltage, then a zero potential corresponding to a logic zero is present at the output of the comparator. When a voltage appears at the second input of the comparator, the potential corresponding to a logical unit appears at the output of the comparator. Thus, if the parameter at start-up is changed according to the technological requirements of m-, or if the protection for the set of parameters 1 did not work, then the corresponding parametric word is zero. A change in any word in a word at time T j to the opposite with respect to the previous time T. is called an event.

When the structure of the parametric word is

where X is O or 1, and each digit characterizes the information of its sensor.

There are two extreme cases: none of the comparators has worked - the parametric word is zero, all the comparators have worked - the parametric word is unity. There are various possible combinations between these extreme cases.

Examples of parametric words in relation to the considered example are given in table 1.

Each block of analysis of parameter changes serves to determine the inequality of two parametric words: current at time T, and preceding at time Tj. In addition, block 3 is also designed to generate signals in block 10 and transfer the parametric code to block II and (memorizing temporal information) in determining the inequality of parametric words.

First register 4 is used to momentarily store the parametric word code at the current time T, the second register 5 is used to store the parametric word code at the previous time t.

meaningfulness and polling of the first matching circuit 7.

The first polling generator 9 is connected by a control input to an operative sampling unit 18, which in the parameter registration mode gives an enable signal, and in the information processing mode - a inhibit signal, which ensures blocking of blocks 1 and 3. The generator 9 is connected to each output unit 3 for analyzing parameter changes . The polling frequency is selected taking into account the maximum permissible frequency of operation of the first register 4, node 6 of unequalities, the delay time of element 8, the frequency of operation of the address generation unit 10 and the frequency of operation of block 15 I 1 of storing time information in read-write mode,

Each unit 10 serves to generate the numeric ruler addresses of the corresponding numerical cells of the unit II for storing information of the read-write signal. In the registration mode, the AND element does not work, since a blocking signal is applied to its input from block 18. Signals arrive only at the second clock input. In this case, the recording trigger 46 is set through the OR element 45 to the single state, and the counter 48 sums up one pulse through the counting input, making the transition to the next address of the numerical rulers through the digitizer 49. The pulses from the first output of the polling generator 9 pass through the element 47 match, will generate a read-write signal to the numerical bar of block 11 at the address chosen by the decoder 49, which forms the address address ha. The output of coincidence element 47 sets the write trigger 46 to the initial zero state. The last m-th output of the decoder is connected to block 14. The first and second outputs of block 10 from the output of the matching circuit 47 and from the m-outputs of the decoder 49 are connected to the control inputs of the corresponding numerical lines of block 1I. The element OR 45 has an additional input for supplying single pulses from block 18 for accessing the memory block 11 in the manual control mode.

Unit 11 is designed on the one hand for storing and storing the binary-decimal code of the current time (time word), determined by the time points of the nature of changes in any of the P process parameters, and on the other hand for storing and storing the parametric word. Thus, in block 11, the code N Ng is written into the corresponding number lines, where Nfl is the parametric word code Ng is the time word code. In each of the numerical cells (P is the number of parameters recorded in the fluid; the number of bits in the parametric word; n is the number of parametric words equal to the number of blocks I) there are ha of numerical cells, where m is the maximum number of time points of any parameter with start-up processes or the maximum number of possible events during the registration of pre-emergency and emergency situations (FIG. 3). The number of bits is determined by the code.

The N g code is applied to the first information inputs of all the numerical lines of the block I1 from the outputs of the electronic clock I2 in parallel and respectively. The code N P is supplied from the unit outputs of the second register 5 of each block 3 to the second information inputs of the corresponding cells of the block I1. As a result, when writing in block 11, the code NN is fixed.

The first generator 9 is used to generate polling signals from block 10, both in registration mode and information processing mode, when the second generator 13 is blocked from block 18, to control the operation of blocks 14 and 15. The first output of generator 9 is used in both registration mode and and in information processing mode, i.e. This generator output performs both a polling function and a query function. The frequency of the pulses from the first output is chosen below the frequency of the second generator 13, i.e. The second output of the generator 9 is used only in the information analysis-processing mode. Therefore, inside the generator 9, before the second output, an AND element is established, controlled by the control output of the operational sampling unit 18.

The control unit 14 (Fig. 2) is designed to manually and automatically set shifts, allocate a discharge number for analysis and form

Start sensor number for each 1-bit parametric word.

Element 22 is a multi-code scheme implementing the logical operation I. The signal at the output of element 22 appears when counter code 20 becomes 1 + 1, which signals that the required number of shifts ml has been generated, i.e. m shifts for 1-g bits of a parametric word, so that when analyzing each bit, view all m numerical lines.

The coincidence element 23 is connected to the zero outputs of the counter 21. The zero state of the trigger at the zero output has a high potential, and the unit output has a low (zero) potential, and with a single state of the trigger, vice versa. Element 23, as well as element 22, is a multi-input circuit implementing 5 logical operation I. In element 22 of the polling input node, and element 23 has a polling input. A single signal at the output of element 23 appears when polling with a pulse of positive polarity only when the counter 21 is in a zero state. The zero state of the counter 21 means that the required bit number has been selected for the analysis, the code of which is specified by the counter 20.

The shift generator 24 is designed to form the synchronization pulses of the parametric word shift in the signal selection register 25 i of the required bit number and the analysis signal. The signals at its outputs are delayed relative to each other.

The frequency of operation of the imager .51 is higher than the frequency of the pulses arriving at the input of the generator 24 from the second output of the generator 13 (f (, n,) "This is due to the fact that the generator 24 must respond to a single pulse of the generator 13 by a series of pulses the number of which is determined by the number of the analyzed bit. The condition for selecting the frequency fp of the generator 24 shifts will be considered when describing the principle of operation of the device.

The number of the sensor number, information from which is included in the analyzed parametric word.

The event analysis block 15 (FIG. 2) is used to analyze the discharge of a parametric word obtained from block 11 by shifting the limit number, which is formed by block 14, generating two commands for the control inputs of the adder 16 DC and DC PC, where DC and PC - additional and direct codes for issuing time; N. time in the adder 16 and in the block 17 of registration and display of information, as well as the Allow print signal.

Register 25. is intended to receive from the block 11 a parametric word code NP and perform a shift operation (in particular to the right) on a signal received at the synchronization input from the first output of the shift generator 24. A link is received from the memory block 11, which is divided into two parts: N - arriving at the single inputs of the register 25; N - on the single inputs of the register 36 time.

The adder 16, connected by the input buses to the output of block 15, and the outputs to the second digital inputs of the recording and display unit 17, serves to determine the duration of the parameter change and output it to block 17. In the initial state, the adder is in the zero state, except for the first bit, which is set to 1. If the duration of the parameter change is found, the smallest must be subtracted from the larger time value. However, during registration, and thus during information processing, the time values come from block 11 to adder 16 through block 15, starting with a smaller value. Therefore, first, the time code of the previous time instant Ng (t.) In the additional code is entered into the adder, and then the time code of the next time instant N in (Ь,,) in the forward code using the commands Record DC and Record PC. Since in the mdpd discharge of adder 16 is 1, the DK entry command carries out the entry N (t.) In the adder 16, and an additional code is obtained, since DK is OK + 1. As a result of the summation of the DC

and the PC gets the difference N (, (t.) - -N "(t;) dN c, where Nj is the duration of the parameter change.

A BLOCK 17 connected by analog inputs to information sensors of the technological parameters, the first and second digital inputs to the digital outputs of the electronic clock 12 and the outputs of the adder 16, respectively, and the third information inputs to the second outputs of the block 15 through which the print resolution is fed and information for printing, intended for recording analog and digital information. The number of the parametric word (from the operative sampling block 18 connected by the control outputs to the control inputs of block 17), the sensor number of the beginning of a parameter change or protection (from the decoder 55) events (from the trigger output 33 of block 15), starting times and the end of the parameter change (from the output of the register 36, block. 15) and the duration of the parameter change (from the outputs of the adder 16).

The unit 18, executed as, for example, a set of buttons and toggle switches, serves to control the address forming units 10, the first and second generators 9 and 13, the electronic clock 12, the shift shaping unit 14 and the information recording and display unit 17. With these blocks, block 18 is connected by a chain of control permission-prohibition. Indicator bulbs are also built into unit 18.

The principle of operation of the device is illustrated by two graphs of the change in the technological process (Fig. 3), where X J is the graph of a possible change in one of the parameters of the starting process of the power unit; Xj is a graph of a possible change in the protection status of a single channel (sensor), with X and X being continuous and discrete functions of the time argument t, respectively. The time difference at points t, tj, t, (. J and t .. simplify and does not violate the generality of reasoning.

As can be seen from graph X, the nature of the behavior of the parameter on the time intervals T, -, t, tj - t, ..., t., - t, .1 is different, which is equivalent to repeatedly interrupting the monotonous process,. The change in the behavior of the parameter X, occurs in points

tj, t,. .., t, which must be recorded, stored and stored in the device’s memory, all points except

are both the end of one interval and the beginning of another. In the prototype, a double point value is confirmed by an end sensor signal and a start sensor, and recorded in a memory device. Therefore, the number of numerical lines is respectively equal. However, this solution leads to redundancy of information, since the information from the start sensor is opposite to the information from the end sensor, i.e. one information excludes the presence of another. The proposed technical solution uses a different principle - the principle of recording and storing information only from start sensors, when their state changes to the opposite, prohibiting, and the information of all sensors relating to the same process parameter forms a parametric word, and the start time codes in which an event occurs, form a temporary word. At the same time, the number of bits in the numerical scale increases by the number of bits of the parametric word, but the number of lines of numbers decreases to m k. The number of bits in a temporary word is much larger than the number of bits of a parametric word, so such an approach allows to reduce the information storage capacity. Memorizing a parametric word that carries information about events makes it possible to determine the root cause of a technological parameter change and restore the entire picture of the development of events over time (which is impossible in the prototype) with automatic detection of the duration of events at the stage of processing and analyzing information by sequentially referring to one of the numeric arrays block 11. In the prototype, when two or more sensors of the beginning (or end) are simultaneously related, they belong to the same block of fixation of the beginning and end the change time, the time is fixed in the memory block, but it remains unknown which sensor worked first or the fact that they worked simultaneously

but. In addition, with the simultaneous triggering of a single start sensor and any end sensor, an uncertain situation is obtained. This is iklyulyucheno in the proposed device. From graph X, it is clear that the principle of fixation and registration of its characteristic time moments is similar, only in this case it is expedient, by analogy with the first process, to combine several protection sensors and read the information in the same way as in the first case, as a parametric word. Along with this, such a construction principle allows at least an order of magnitude increase in the number of registered parameters, and therefore expand the scope. Indeed, if a prototype is used to record the time of protection operation (graph. Xj) or try to eliminate these drawbacks when registering launch processes (graph X,), then only one protection or start sensor must be connected to each 5th home fixing unit. end, and the protection sensor must be two-position (for example, normally open and normally closed contacts). Connecting one sensor is ineffective since each sensor requires an address generation unit and a self-storage unit. Let, for example,. Then, in the prototype, it is necessary to have 160 address formation units, and in the proposed device, if you choose, for example, as discussed in Table 1.

The analysis of the parametric word is based on two principles. The first principle consists in the sequential analysis of information in each of the n numerical cells. The second analysis principle consists in the sequential viewing (analysis) of the same bit number of each of all m numerical lines of the selected cell of the storing unit 11, starting with the first bit and ending with the 1st bit. As a result, the number of views for each bit is mxl, where 1 is the bit number.

Let, for example,. Since the analysis in each category is carried out similarly, it is sufficient to consider only one bit, for example, the first one. For simplicity, we will restrict what is not

violates the generality of reasoning, since the number is m 5, we include all possible combinations, and the rest can be considered a repetition, for example, of the last combination (see Table 2).

In Table 2, the specific information is indicated only in the first category, in other categories it can be any, and the information is unchanged.

Let us analyze these words from the standpoint of the influence of a particular bit, for example, the first, on an event: 1 - no event; 2 - event (transition from O to 1); 3 - no event (1 remained); 4 - event (transition from 1 to O); 5 - no event (O remains). From here we see that an event can take place only in two cases: when the word goes from O to 1 and when going from 1 to O. The first case is easier to detect, since the initial state changes to the opposite, and When analyzing the second case, one should know whether 1 was at the previous moment of the analysis.

In case of a bottom-up analysis, it is necessary to clearly distinguish three points: select the point at which the analysis is resolved; to have information on the analyzed bit number at the current time; to have information on the same bit number at a previous point in time, in particular, to know whether it was 1.

The frequency of operation of the generator element 51 generation is selected from the condition:

where 1 is the number of bits in the parametric layer

(the unit in the numerator takes into account the possible loss of impulse due to the mismatch of the signal fronts with 52 and with 51).

which means that the required number of pulses must pass

before the occurrence of the next pulse from generator 9. Here i y is the pulse duration; T j,, - the period of the following pulses of the generator 13.

The frequency of the generator 9 is selected below the frequency of the second generator 13, since the request frequency, as in the prototype, depends on the printing speed and should not exceed it. .

The proposed device has two modes of operation, between which there is a clear boundary. At first, the device operates in the mode of receiving and registering information, and at the end - in the mode of analyzing information processing, the mode being set by the operator.

The device for recording time and information processes works as follows.

In the initial state - (Fig.) Or when the device is turned on, the blocks 3,10, 14 and 15 are blocked by supplying prohibition signals, to the inputs of the generators 9 and 13, and to the second inputs of the blocks 14 and 15. All blocks are set to their original state tion, in the adder 16 is written unit of the younger bit.

The electronic clock 12 can operate in two modes: continuous and periodic. In continuous mode, the electronic clock through the decoding and display units of block 17 shows the current time, and during periodic operation it is in the zero state. In this case, the clock is set and corrected. Registration of analog information in block 17 is prohibited.

When starting the device for registering time processes, the electronic clock 12 is corrected, the lock is removed from the first output of the generator 9 and from the output of the second generator 13, the block 17 of registration and display of information is fully operational.

Subsequently, the device operates in the mode of receiving signals from information analog sensors of parameters, the nature of changes in information about which is displayed in the form of diagrams on the recorders of block 17. At the same time as changing parameters at characteristic time points, the start sensors or process protection sensors switch. The second poll generator 9 is continuously determined

The first frequency polls the first register 4 in each block 3. Information from the outputs of the comparators of each block 1 is entered into the first register and compared with the non-difference node 6 with the information of the previous polling cycle, which is stored in the second register 5. exactly with the inequality of parametric word codes. In this case, the onpoca signal delayed by element 8 passes through the matching element 7, enters the new register in the second register, and automatically sets the next address of the numerical range of the corresponding cell 11 through the second clock input of the address generation unit 10. the input of the generator 9 with the arrival of the signal at the second clock input in the block, a read-up signal is generated at the set address. In this case, the selected numeric ruler of block 1 is written after reading the pair

metric word N from the output of the second register 5, a. from the outputs of the electronic clock 12, a temporary word N. Thus, in block 11, parametric words that are different from each other are recorded. The end of the recording of information is carried out either for a certain period of time or when the third output of block 10, which is used to signal the filling of each of the cells, appears.

Consider the timing of the device in the mode of reception-registration of information (Fig.7). Parametric words are located on the timeline vertically, starting with the first bit at. Parameter word codes, taken for example, are listed in Table 3.

Of the parametric words given in Table 3, only three characterize the event: the second, third and fourth. The first word is zero and corresponds to the initial state of registers 4 and 5, and the fifth word is equal to the fourth. Consequently, according to the principle of operation of the device in the mode of reception-registration of information in block 11, three words should be written: 2.3 and 4.

The output pulses of the generator 13 are shown in FIG. 7a. 7, although arbitrarily, the period of the pulses of the first generator 9 of the survey is difficult, if its frequency is much lower than the frequency Top. Therefore, the period of the pulses of the generator 9 is selected 1.5 times longer than the period of the generator 13 TOR, 1.5T (, that does not violate the generality of reasoning, and at the same time the ratio f op, ω is observed. The magnitude of the delay of element 8 is necessary for

parametric words in register 4 and the operation is not - equivalence in block 3. The graphs in Fig. 7c-k characterize parametric words in accordance with Table 3 on time intervals t - t ,, t - t, tj - tj, and so on. d. in accordance with the time intervals fig.Z. The delays associated with switching elements are not taken into account in FIG.

Thus, the insertion of a parametric word into register 4, characteristic of the time interval t - t, j, leads to a mismatch of the comparison codes with the interval t. At the output of node 6 of unequalities, the signal Unequalities appears (Fig.7). When the signals from the output of the element 8 and the node 6 coincide, the output of the element 7 appears (Fig.7m), which enters the parametric word code into register 5 from register 4 and starts the address generation unit 10 (Fig.5). Trigger 46 block 10 switches to vi. The polling of the state of the block 10, in particular the trigger 46, is made by the polling generator 9 having a frequency exceeding the maximum frequency of operation of the start sensors or protection sensors (fig.7n). Poll pulses from the generator 9 entering the coincidence circuit 47 generate a readout signal - write to block II (fig. 7p). On the remaining time intervals, tj- t, etc. work is similar at the previous intervals.

The mode of analysis and information processing can be automatic and manual.

In the automatic mode, blocks 3 are blocked, permission is sent to the first generator 9, to one of the blocks, 10 permission is given to form a request signal instead of signals.

the information received in the reception-recording mode via the first clock input from block 3, the registration of analog information in block 17 is forbidden, the electronic clock is blocked, the first and second registers 4 and 5 are set to O, in counter 20 is locked for analysis selected parametric word from the first section.

In this case, the selected block 10, due to pulses from the first output of the generator 13, periodically changes the addresses of the numerical rulers of the corresponding numerical cell of the block 1I. The code of the parametric word read from the storage unit 11 is fed to the register 25, and the time word code to the register 36. Synchronously with the address generation unit 10, the shift shaping unit 14 is operated by pulses from the second output of the first generator 9. The content of the counter 20 is transmitted sync

A pulse with a delay of v in the counter 21. With a delay, pulses appear on the first code of the shift generator 24. The first pulse shifts one bit to the right in register 25 of the event analyzer 15, and its value is transmitted to the trigger 26 At the same time, with the same pulse, one is subtracted from the contents of counter 21, and it switches to O. With a delay for the duration of the pulse, the first pulse is interrogated by a matching element 23. Since counter 21 is in O, the polling pulse passes to its output, register 25 is triggered in O and sets trigger I to 27. Next, with the delay, the same pulse by

tata. Before considering the operation to analyze the result, we note that after the first impulse. From the first, second and third outputs there will be next pulses, the number of which must be at least 1 + 1.

The next impulse arriving from the first output of the polling generator 9 again starts the selected address generation unit 10, and the impulse from the second output of this generator performs the considered operations, i.e.

If the triggers 26 and 33 are respectively in 1 and in O, the interrogation signal from the output of element 29 passes through elements 31 and 37, sends the DK entry command to the adder 16, forms the Print Resolution in block 17 through the OR 35 element, and through the input register register 36 transmits the time parameter code N (

An analysis of the first digit of the second numeric ruler is performed. The same procedure is repeated until the third output of the selected address generation unit 10 to the counting input of the counter 20 through the signal assembly 19 receives a signal that indicates that all m numerical lines of the unit 11 are counted. for analysis. This signal switches the counter 20 and thus issues a task to animate the next bit of the parametric word.

Similarly, the block 14 operates until the code 1 + 1 is locked in the counter 20. In this case, the output of the coincidence circuit 21 is the signal that sets the counter 20 to O.

: The bit value recorded in trigger 26 is analyzed by a signal from the first output 1 of the generator 24 shifts using elements 28, 29, 31, 31, 34 and 5 37 coincidences taking into account the states of the triggers 27 and 33.

The trigger 27 determines the moment of analysis of the discharge of the parametric word.

If it is in O, then any result (1 or O) in trigger 26 is reset without analysis. When the trigger 27 is set to 1, the analysis is carried out via the coincidence element 29 connected by the input to the single output of the trigger 27. In this case, the output signal of the element 29 interrogates the coincidence elements 31 and 32 connected by the first inputs to the single and zero outputs respectively. trigger 26. The zero state of trigger 26 directs the interrogation signal through element 32, to one state through element 31. The further passage of the signals depends on the trigger drop. In the zero state of the flip-flop 33, the signal from the output of element 32 arriving at the first input of element 34 does not pass to the output and is lost.

to the adder 16 and to the block 17, to which the state 1 or O is also transmitted. In addition, the output signal of the element 37 switches the trigger 33 to 1, fixes the event, the trigger 27 sets it to O and sets the trigger through the OR element 30 26 to zero state. Further passage of signals from the output of the element 31 through the element 37 is impossible, since the second input of the element 37 has a inhibitory signal from the inverse output of the trigger 33. Thus, the trigger 33 does not allow the registration of a re-event in the analyzed bit. Such a situation of repeatability of events in the analyzed bit is inevitable, since the event can remain for a long time in one bit, and in others - change.

Subsequently, the polling signal from the output of element 37 can only be matched if the event changes in trigger 26 (from 1 to O). In this case, the polling signal passes through elements 32 and 34, dropping trigger 33 to O. At that, the command PC entry is sent to the input of the adder 16, through the element OR 35 - Print resolution and transfer of Ng to blocks 16 and 17. After the change of event ( from 1 to O) block 15 returns to its original position.

The operation of the block is in accordance with table.4.

From Table 4 it can be seen that the sixth situation is a repetition of the second.

If an event occurs when analyzing a bit, then the commands DK or PC registration, Print resolution should be executed. These commands in the table. 4 summarized and named Resolution. If the commands are not executed, then - Ban. A dash, respectively, is 1 or O (the presence or absence of a signal).

Consider the fact that the excess pulses from the outputs of generator 24 do not affect the operation of block 15. If trigger 27 is in O, then no command can be executed in any state of trigger 26. After installing counter 21 in O, when deducted, trigger 27 is reset to O

however, the counter continues to operate with an excess of pulses. After the zero state, the counter 21 is set to the one state by the next pulse, which decreases. This means that the allowable number of excess pulses in the counter 21 is equal to its recalculation ratio, since after that it is set to O again, which leads to the installation of the trigger 27 to 1, which is unacceptable. Thus, by choosing the appropriate number of bits in the counter 21 or / and by choosing the magnitude of the delay, a rather large excess of 1-puls can be allowed, i.e. to ensure the performance of shift-analysis at high frequency, and since only one of the high-frequency pulses is in the presence of an event initiating the execution of commands at the output of the event analysis block 15, their frequency of occurrence will not exceed the frequency of the pulses at its input.

In the manual mode of analyzing and processing information, the device operates in the same way with the difference that single request pulses are sent to block 10 and the outputs of the first generator 9 are allowed to be generated in the same way as in the receive information reception mode, i.e. the automatic generation of a signal instead of the signal from the change analysis block 3 is prohibited. This function is performed by the operators themselves.
