1 shows a block diagram of the device; figure 2 - graphs, explaining the principle of its work.

A device for registering parameters of technological processes contains (Fig. 1) blocks 1 for fixing the beginning and end of changing parameters, shapers 2 addresses, block 3 of memory, first generator 4 of pulses, block 5 of the current time, adder 6, block 7 of display and recording, control panel 8, unit 9 for switching operating modes, performed on element 10 OR, trigger 11, element 12 AND-NOT and element 13 OR, second pulse generator 14, driver 15 of control signals, you (completed on element 16 zadder; kki and trigger 17, mode setting blocks 18 Started, each of which is formed on the trigger 19 and elements 2023 2 I. Each vsholnen address generator on the element 24 or, the trigger 25, the element 26, the counter 27 and decoder 28.

The first and second inputs of the device are connected respectively to the sensors 29 of the beginning and end of the change of parameters and information sensors 30

The principle of operation of the device is illustrated by two graphs of technological process change (), where X is a generalized graph of a possible change in one of the parameters of the start-up process of a power unit; X2 is a graph of a possible change in the protection status of one channel (sensor), with X and X being respectively continuous and discrete function of the temporal argument.

The device for recording technological process parameters operates in three main modes: in reception-registration mode, in reception interruption mode, and in processing analysis mode.

In the initial state or when the device is turned on, the blocks 1 of fixing the beginning and end of the change are blocked through the element 13 STI by setting the interrupt trigger 11 to state 1.

Triggers record 25 and counters 27 blocks 2, adder 6, triggers 19 records blocks 18 and trigger 17 request

shaper 15 is in the zero state.

Unit 5 (electronic clock) can operate in two modes: continuously and periodically. In continuous mode

electronic clock 5 through block 7 shows the current time. In periodic operation, the clock 3 is in the zero state. In this case, when the device is turned on, the clock is set or corrected during continuous operation.

When the device is started, the block is unlocked from blocks 1 by setting the trigger 11 for interrupting block 9 in

That which allows the polling pulses to pass through the NAND 12 element to the second (clock) inputs of the address shaper 2, the entire block 7 enters into operation.

Subsequently, the device operates in the mode of receiving signals from information analog sensors 30, the nature of changes in information from which is displayed in the form of time diagrams on recorders, such as KSP-4 unit 7. At the same time as the parameters change, the discrete signals occur in the characteristic time points in blocks 1 with sensors 29 start and

end of Parameter change. The signals from the sensors 29 of the beginning of the change of parameters set the corresponding block 1 to state 1 for a certain time, due to the formation

the record, the receipt of D e from generator 4 through the element IS-NOT 12. The output signal of the element 26 and sets the trigger 25 records in the state O, which performs a reset unit 1 in the state O, Simultaneously the unit enters the binary counter 27 transitions, which generates the next binary address of the beginning of the parameter change for memory block 3, the 1 signals from the output of element 26 AND and the decoder 28 arriving at the read-write inputs and address inputs, as well as the signals of the clock 5 at the information inputs of block 3 result to update info ation to the selected address with preliminary schitgoaniem. The time of the end of the character change parameter in each cell of block 3 is recorded similarly by the signal from sensor 29 by installing unit 1 in a new state 1 on another channel, which sets the recording trigger 25 to state 1. Interrupt reception of information occurs automatically when one, several, or all information cells of the memory block 3 are filled. The filling cells are monitored using signals from the last outputs of the decoders 28 of the driver 2 addresses. This signal leads to the installation of the flip-flops 19 of the printout of the respective blocks 18 to state 1 through the second element 20 I, which sets the corresponding transition counter 27 into O. The interrupt trigger 1 through the element 10 OR signals is set to 1, stopping the arrival of polling pulses to the address generator 2 and transferring control to the driver 15 by sending a signal from the output to the OR element through the delay element 16 to the single input of the request trigger 17, which allows the generation of pulses generator 14 to serially connected blocks 18. Next, the device operates as described when considering the operation of blocks 18. The request pulses transit through elements 23 and those blocks in which the triggers 19 are IB o, and at state 1 flip-flop 19, loop through element 22 and to the clock input of the corresponding shaper 2 addresses, skip the pulses at its input until the decrypt 28 of the shaper 2 signal, which sets the corresponding trigger 19 of the printout to O. The next impulse passes in transit, to the next driver 18, analyzing the state of the trigger 19, and so on until it reaches the highlight of the first (the normalizer 18, the signal from the first generator of the first driver 18 sets three ter 17 request in G and transmits the control unit 9 interrupts the installation of the trigger 11 in G, which allows the passage of the interrogation pulses to the first clock input of address blocks 2 and unlocks the fixing unit 1 changes the start and end parameters. After that, the device returns to the reception-recorder mode of the input information. In the interrupt mode, the device operates in the PARTIAL analysis and information processing mode of one or several information cells of the memory block 3. Therefore, in this mode, a sequence of pulses generated by block 18 goes to the third input of the OR element 24 of the corresponding shaper 2. At the same time, the flip-flop 25 of this shaper 2 periodically changes its state, as in the operation of the beginning and end fixing block 1. Since at the second input of the element 26 And there is an enabling signal, the differential passes to the output of the element 2C And generates a read-write signal. From block 3 of memory, at the selected odd address (start address), the time code is read into adder 6 in the supplementary code, and at the even address (end address) in the forward code. The time interval codes obtained in the adder 6 are transmitted to the display and recording information unit 7 for printing with an indication of the recorded time and the number of the numerical array. The analysis and processing of information takes place after the completion of the technological process (for example, for start-up processes) or after a certain control time interval (for example, during the registration of protection, pre-emergency and emergency situations). It can be automatic, semi-automatic and manual. In the mode of analysis and processing of information, the start and stop fixing blocks 1 are blocked directly by the signal from the console 8 through the second input of the element 13 OR and additionally from the interrupt trigger 11, which is set to 1 n, it prevents the polling pulses from the first clock inputs of the address 2 drivers , the adder 6 and the request trigger 17 are set to the zero state, and the continuous information recorders of block 7 are disabled. The information (fourth) inputs of memory block 3 are blocked. In the automatic mode of analyzing and processing information (most preferable in terms of speed), the operator sets all triggers 19 prints of blocks 18 to state 1. In semi-automatic mode, one of flip-flops 19 to state 1 Then the flip-flop 17 is set to state 1. Further operation of the device is no different from the considered partial analysis and processing of information in the interrupt mode receiving information. The end of the printout in the automatic mode is signaled by the display element on the remote control 8, when the print trigger 17 is set to the state O. In the automatic mode, all n informations and ionic cells are printed, and only one memory unit 3 is printed in the semi-automatic mode. Therefore, the specified procedure must be repeated many times. Manual mode is usually used in control mode. In this mode, from the console 8, single request pulses are fed directly to the address generator 2 through the quarter element 24-OR (this input is not shown in FIG. 1, since this mode is auxiliary.
