Information recording devices / ш are known, containing a register connected to a control unit and decoders, the outputs of which are connected to the block of writing electrodes ll and 2 through logic elements OR and the block of drivers. Low fixation accuracy of the monitored parameter is the disadvantage of these devices. To the proposed is a device for recording information, containing the first distributor pulse generator and serially connected counter, the first decrypted p, a block of drivers and a record block, one of the inputs of the first distributor is connected to the installation inputs of a pulse and counter generator, the device synchronization input is connected to the corresponding inputs of the first distributor and a pulse generator, the first output of which is connected to the pulse inputs of the first distributor and counter 13 Known device , registration is based on an analog registration method, in which the ordinate corresponds to each point of the recorded parameter in a definite way: the scale is analog in Parameter value. Possessive, this method is characterized by low registration accuracy. The result of measuring the registered value of a parameter when processing castings depends on the restoration using scaled rulers or W2 tools. The registration error is directly dependent on the display master. The purpose of the invention is to increase the accuracy of the device.

This goal is achieved by the fact that it additionally contains a dot formation block, 1 digit is depicted, a second distributor, a second dashifraor, a block of OR elements, an inverter, the first and second And elements, one of whose inputs are connected to the outputs of the G1 pulses generator, another input of the first And element connected with another output of the first distributor, and the output with the input of the second distributor, one of the outputs of which is connected to the corresponding input of the first distributor, and the other outputs to one of the inputs of the forming unit digits, other inputs

which is connected to the outputs of the second decoder, the inputs of which are connected

FIG. 1 is a block diagram of the device} in FIG. 2 - the construction of numbers applied to the tape carrier. The block diagram of the device (Fig. 1) includes a Tina 1 clock signal, an inverter 2, a first distributor 3, a generator of 4 pulses, an element 5, a second distributor 6, a counter 7, an element 8, the second and first decoders 9 and 10, a block 11 formation of a bitmap of figures, a block of 12 elements OR, a block of 13 forms of users, a block of record 14. Block 11 for forming a dot image of numbers consists of blocks for recording lines (in the form of points), inclined 15, vertical 16, horizontal 17 and block 18 for recording individual missing points, as well as block 19 an element OR. The input of the first distributor 3 and the control input of the generator 4 pulses are connected to the input width 1 of the synchronizing signal, and the first output of the generator 4 is connected to the control inputs of the counter 7, the first distributor 3 and the first input of the And element 8. The first output of the first distributor 3 is connected to resetting the inputs of the counter 7 and the generator of the 4 pulse, and the second output is connected to the first input of the element 5 and through the inverter 2 is connected to the second input of the element 8, the output of which is connected to the control input of the decipher 10 the second output of the gene The generator 4 is connected via the second input of the element 5 to the second distributor 6, one of the outputs of which is connected to the second control input iiepBoro of the distributor 3, and the remaining outputs are connected to the first inputs of the digitizing unit 11. The outputs of the counter 7 are connected via a decoder 9 with the second inputs of block 11, the first and second inputs of block 12 of OR logic elements are connected to the second outputs of the device 1O and to the outputs of block 11, respectively, and the outputs are connected via block 14 of recording. Block 11 of forming a dot image of numbers (Fig. 1) consists of M formers 2O X., X2 ,, .., X pulse sequences for recording digits of digital values of the parameter, each of which contains .T blocks 15,16 , 17, 18 to write the elements of the configuration of numbers, with There are respectively inclined, vertical, horizontal lines L in the form of points and separate points, the first inputs of which are connected to the corresponding first inputs I, IJ, Uiiiy and V of block 11, and the second inputs are connected to the corresponding second inputs X., X .. ,, X block 11. Each of the three outputs of the blocks 15, 17, 18 and two outputs of the block 16 is connected to the block 19 of the OR elements, the output of which is connected to the outputs of the block 11 forming a point image of numbers. The device works as follows. The recorded information in the form of the h of the binary binary code is entered into counter 7. The synchronizing pulse 1, which accompanies it, triggers the generator of 4 pulses and arrives at the first distributor 3. In the recording mode of the analog value, the pulse from the output of the generator 4 through the And 8 element allows the information to pass through first desh4t ator 10 and block 13 shapers on block 14 of the record. In this case, an enabling signal from the second output of the distributor 3 is fed to the And 8 element through the inverter 2. This same pulse arrives at the control input of the counter 7, increasing its content by one with the falling edge after registering the initial information. The signal at the first output of the distributor 3 zeroed the counter 7 and the generator of 4 pulses. The analog recording cycle has ended.

When marking, the signal from the first output of the distributor 3 is not received, and the counter 7 with the generator 4 is not zeroed. Therefore, the second pulse from generator 4 records the contents of counter 1, incremented by one. Thereby a marker point is recorded. The number of marker points is established by the distributor 3 by counting the pulses from the generator 4.

After applying the required number of marker points, the signal from the second output of the first distributor 3 allows the passage of pulses from the second output of generator 4 through element 5 to the second distributor 6. In addition, this signal, having passed through inverter 2 using element 8, prohibits the passage of pulses the first output of the generator 4, i.e. registration of graphic information is terminated.

Then follows the mode of registration of information in digital form.

The second distributor 6 outputs five pulses 1, P, W, 1U, Y to the block 11 for forming a point image, at the end of which a signal is sent to the first distributor 3. The signal from the first output of the distributor 3 zeroes the counter 7 and the generator 4 pulses. The registration cycle has ended, and the device is ready to receive and register the next one.

Block 11 generates from pulses 1, P, lU, iy, y 3N pulse sequences, which through block 12 of the OR elements and block 13 of the formers arrive at 3 writing elements of recording block 14 for reproducing the N on a carrier tape. All numbers are recorded simultaneously. The sizes of each digit are determined by three pulses in width and five pulses in height (Fig. 2).

The digit image forming unit 11 includes digital value setting cells X., Xj, ..., Xjg of the parameter value consisting of blocks for recording individual elements of the configurations of numbers, i.e. oblique 15, vertical 16, horizontal 17 lines and individual points 18. The input signals of blocks 15,16 are five talpuls 1, P, W, 1U. Block 17 - pulses 1 | W, Y, and block 18 - pulses 1 , P, 1U, U. The second inputs of the blocks 15,16,17 18 are supplied with signals from the corresponding outputs of the machine (| chator 9, and in block 15 the signals X- are used), which include the recording of the tilted lines of digits 2,3, 6,7,9 5 in the block 16 — X signals for recording vertical lines — digits 0,1,4; in block 17 — signals for displaying horizontal lines of digits 29, 0; and in block 18 — signals Xjl for fixing individual points in numbers 1,2, 4-7. 9, the output pulses of blocks 1518 follow through block 19 of the elements OR to the output of block 11. Blocks 15, 17,

0 18 distributes the pulses to the three writing elements of the writing unit 14, and the block 15 to the two.

The decipheror 9 sets the signaling image of the required digit on one

5 of 1O-TI for each cell of the formation of pulsed sequences.

Thus, of the five pulses of the detector 6, pulsed

0 sequence for displaying the digits of the digital value of the monitored parameter on the carrier tape.

The device works in 3 modes: display of graphic information, its

5 of marking and recording of digital values. For this, the valve 3 determines the number of marker marks and the period of marking of graphic information, sets the start of registration of digital values.

0 parameter, and also prepares a counter 7 and a generator 4 for receiving new information.

The recorded information in numbers is increased by one as a result of adding one to the counter 7 dg. labeling grafshsky information.

The use of digital registration in conjunction with a graphical analog display of the monitored parameter will improve the accuracy of registration.

In addition, the accuracy of the readings of the controlled parayet from the carrier tape in the intervals, at non-digitized registration points, is improved due to the use of interpolation, relying on digits. The effect of factors distorting the analog values of the monitored parameter, which are characteristic of a known device, is reduced. As practice has shown, the error of registration in relation to and to the conventional device can be reduced from 4-5% to 1%.

To record analog value as

5 and for its digitization, common writing elements are used, which allows reducing their number and making more efficient use of them.
