Figure 1 shows the block diagram of the device; Fig. 2 is a block diagram of a simulation block of current values; FIG. 3 is a functional diagram of the control unit. The device comprises a switch 1, a time shift compensation unit 2, a time code allocation unit 3, a channel selection unit 4, a data selection block 5, a computer word generation unit 6, a parameter matching unit 7, an array address generation unit 8, a data format conversion unit 9, control unit 10, magnetic storage unit 11, control unit 12, filter unit 13, video terminal interface unit 14, current value modeling unit 15, device inputs 16 and 17, outputs 18 and 19, duplex communication with video terminal , communication 21 and 22 with EV M through the interchangeable computer interaction unit, the first register 23, the OR element 24, the AND 25 group element, the group register 26, the multiplier 27, the AND group element 28, the group register 29, the second register 30, the group element 31, the group register 32, adder 33, control unit 34, group element 35 and 35, group register 36, trigger 37, pulse generator 38, counter 39, decoder 40. Sources of measurement information are specialized external devices (VCA), which include, for example, multichannel magnetic code drives, converters, sensors, etc. The device operates as follows. Information from the VCA is fed to the input 16 of the device in the form of a specific sequence of codes of different size and structure, the totality of which constitutes an information frame. Unit 1 performs switching of the selected data source and matching its output by electrical parameters with the input of the device. In the case of working with multichannel code magnetic storage devices from block 1, the information enters block 2, which accumulates the next information word in the buffer register and, with a pulse of a certain amount, escorts it to block 6. In this case, time shifts are computed reproduction of measuring information from magnetic tapes. A combination of official information (time codes, signs of the beginning of a frame — markers, signal marks, etc.) enters blocks 3-5. Block 3 is used in cases when a registered time code is received from an external device. In this case, the block performs the necessary operations for the selection of a time code, which is involved in the sequence of reference pulses, as well as its selection from certain channels during channel registration. In addition, block 3 converts a serial code into a parallel one, a binary code into a decimal one for analysis and subsequent recording onto a magnetic tape of a storage device, computer. In cases when registrations are subject to information arrays limited by specified time intervals, the comparison signals of the current and the time codes specified in the device arrive at block 6, allowing or prohibiting the passage of information to form a computer word. BJ: OK 4 is intended for selecting those frame channels, information from which must be registered on the NML computer for subsequent processing or reduced to a physical value in block 15. The block allows to perceive information frames with a variable number of channels. The permission signal for selecting the specified channels goes to block 6. The number of the selected channel can also be issued to block b for subsequent registration to the NML along with information about this channel. Block 5 selects incoming data, controls their passage to block 6. In this case, the number (series) of frames, information layers, the time interval for input into the computer, as well as the number (discreteness) of frames, information words, time interval are specified. for prohibition of input into the computer. In addition, the block analyzes service marks (marks of occurrence) registered by the source of information in order to fulfill the specified initial conditions for recording information on the NML of the computer upon their arrival. Block b ensures the formation of machine words of a certain unified size and structure from informational and service words of various (depending on the type of VCA) size and structures coming from blocks 2-5. To simplify the algorithm for searching information in a computer and processing it, the output information from the device contains service bits, the corresponding code of which is a sign of the beginning of a frame, a time code, identification data, a bad word, a bad frame, etc. With the same purpose, the necessary service words with the codes of selectable channels recorded by the current time to the service marks can be recorded on the magnetic tape of the NML computer. In addition, in block 6, the control code of the assembled machine words is formed, which, after the specified input conditions are fulfilled, are output to the filter unit 13. In block 13, the increment value of the current K value of the measurement information is determined and compared with the detected value. If there is an appropriate resolution, control unit 12 removes single random outliers of the studied process, registered in certain channels of the information frame, at the rate of information receipt from the VCA. In this case, an outlier is considered to be a value that differs from the previous one by an amount greater than the increment specified in the device. When outburst X is detected, its value is replaced by the averaged one. The smoothed information comes from block 13 to block 15, Block 7 buffers incoming measurement and service information from the VCA and coordinates the data arrival rates and records of them to the NML computer or read to the video terminal screen. The entry of information into block 7, the break-through from blocks 15, 11, 14 is carried out under the control of block 12. In block 7, two fields of memory of a certain volume are allocated, which are alternately switched to write or read modes. When the first field is filled, the recording continues to the second memory field, and from the first pre-checked parity in the lO block, information is output to block 9. After the second memory field is filled, the recording continues to the first recording field, and the second one is read. To enter information, on the video terminal, the specified amount of memory of block 7 is filled with information read from the magnetic tape of the NML computer which is paged onto the screen under the control of block 14.

During the operation of block 7, block 8 counts the number of information zones when writing and reading data arrays on the NML computer, as well as searching for specific zones, groups of zones and user marks when they are output to a video terminal. From block 7, the information on the signals of control block 12 goes to block 9 for converting data format and simultaneously to block 10 of control. In block 9, each full-information word formed in block 6 is conducted to a strictly defined record format on the NML computer, for which it is split into bytes (lines). Each line of information is supplemented by a parity check bit, which is generated in control block 10. In addition, in block 10, when recording information arrays on the NML, the cyclic checksum (CRS) and longitudinal checksum (PKS) are calculated, as well as the information from parity block 7 is recorded with the number of failures fixed. If necessary, in block 10, a signal is generated to block the process of interaction with the NML in case of failures in the operation of block 7 and in case of errors on the device line — NML type Echo error, Error in the write register, Error in the skew register, PKS error, etc. . From block 9 information comes

in unit 11 of conjugation with the NML, which forms the necessary control actions for interacting with the NML of the computer in the write and read modes.

Writing to the NML (output 18) and reading from the NML (input 17) of the actual arrays and user tags occurs according to certain micro-tacts generated by the control unit 12, with the help of which the coordinated operation of all units of the device is ensured. In addition, block 12 generates the necessary signals to control the NML computer's tape-driving mechanism (output 19). Video interface block 14 is used to form test information arrays and certain user marks (data volume labels, initial and end labels formed by

information file devices, etc.). For this purpose is necessary | the service information is typed on the video terminal screen and through the input 21 and block 11 in the form of zones of a certain length is output to the NML computer. In addition, with the help of block 14, the test read and edit the data read from the NML computer. In this case, the zone specified in block 8 is read through block 11 (input 17) into the buffer memory of block 7 and sequentially, page by page appears on the screen of the video terminal in a form convenient for analysis and editing (exit 20). If there is a printing device in the video terminal, it is possible to document data read from an NML computer.

The current value modeling unit 15 is designed to determine the physical quantities from the current sample values in the rate of their receipt from the VLA taking into account the transfer characteristics of the through measurement and recording path. Block 15 operates as follows.

The transfer characteristic of the pass-through measurement and recording path is uniquely determined by a n-th order polynomial.

The current value of the registered reference x enters block 15, where it is stored in the input register. The values of the polynomial coefficients are set on the device control panel. The coefficient a — the first term of the polynomial — is entered into the accumulating adder, and the other coefficients of the polynomial are stored in special memory registers. The second term of the polynomial is calculated by multiplying the current count value x by the second coefficient of the polynom a. The value of the second term calculated in this way is summed with the contents of the accumulating adder, i.e. with the coefficient a ,, / a X ;; is entered into the intermediate value storage register. The third term of the polynomial is calculated by multiplying the contents of the storage register of intermediate values (i.e. x) with the current value of the reference X .; and the third coefficient 0 of the a2 polynomial. The x value is entered into the intermediate value storage register. And so on. The polynomial term n + l is calculated by multiplying the contents of the intermediate value storage register (i.e.

.n-1

) with the current value of reference

x and the coefficient of the polynomial a „.

The calculated terms are entered into the accumulating adder. After calculating the term n + 1 and entering it into the accumulating adder, it has the current value of the physical quantity FJ, which is output to the buffer memory of unit 7 of the device and then to the NML.

The control node operates as follows.

The synchronizing pulses from the device filter unit 13, through the input register of the unit 15, cocks the trigger 37 of the control unit 34, which in its pile starts the generator 38 of pulses. The pulses from the generator 38 are fed to the counter 39, and the counting results are fed to the decoder 40. The control signals from the decoder arrive at the elements And 25, 28, 31 and 35 of block 15, allowing the sequential passage of the values of the polynomial coefficients to the multiplier 27. The control signal, corresponding to the nth coefficient of the polynomial, simultaneously resets the trigger 37 to the initial state. This cycle repeats with the arrival of the following sync pulse. The multiplexing of a device with different types of computers as part of multichannel complexes of automated experimental data processing is carried out by means of a plug-in unit for interacting with a computer through input 21 and output 22.

The main function of this plug-in unit is to ensure the compatibility of different types of calculators at the level of external memory. In this case, the source of measurement information or processing results connected to the input of the unit 7 of the device is, for example, a mini-computer and the information receiver at the output of the device is an NML of a universal computer. The computer is connected to the device via a software channel through which the necessary information is output to the device. The exchange initiator is a computer.

The proposed device allows defining, forming and recording on the NML computer magnetic tape arrays of physical values of experimental data with the possibility of their display and editing, as well as to realize interaction at the level of the external memory of different types of calculators.
