Description

The invention relates to instrument engineering and can be used in multichannel systems for graphically recording information. A registrar is known that provides registration of information in the form of bars, the length of which is proportional to the value of the controlled parameter (11 This recorder can record only two values of recorded values on a single scan line. The recorder is also known; it registers several monitored parameters in a given zone The recorder is used simultaneously with strnhov and dot recording information. This recorder contains information converters in the time interval and into the label, the brightness modulator If an information recording unit connected to the output of the modulator and information converters 2 inputs. The device indicated does not provide sufficiently high quality recording of the coincidence of the images of the marks and marks, which makes it difficult to identify each of the processes, especially using a recording medium with a low bandwidth. The aim of the invention is to eliminate ambiguity when combining dotted and dashed records in one zone. The goal is achieved by the fact that a logical block for controlling the brightness of tags, the inputs of which are connected to the outputs of information converters, is inserted into a recorder containing information converters at time intervals into marks, a brightness modulator and an information recording unit connected to the modulator output and information converter inputs. , and the outputs - with the inputs of the brightness modulator. FIG. Figure 1 shows a block diagram of a recorder for two dashed and two dotted graphs; in fig. 2 - the location of these graphs on the nose of the recording. The controller contains information time converters 1 and 2 into a time interval, a subtraction circuit 3, a recording area width encoder 4, an input information circuit S, information converters 6 and 7 into a label, an information recording unit 8, a brightness modulator 9, a brightness control logic unit 10 tags. The outputs of the converters 1, 2, 6 and 7 are connected to the inputs of the logic unit 10, the outputs of which through the modulator, 9 luminance are connected to the input of the information recording unit 8, the first output connected to the first inputs of the converters 1, 2, 6 and 7, and the second with the second input of converter 2, the input information circuit S is connected to the second inputs of converters 1, 6 and 7 and through the first input of the subtraction circuit the 3rd third input of the converter 2, the second input of the calculation circuit 3 is connected to the encoder 4 of the recording area width. The logger works in a manner. In block 8 of the recording, the sweep along the abscissa axis is carried out by continuous or discrete movement of the information carrier, for example, electrothermal paper, and the sweep along the vertical axis is performed, for example, with the help of a linearly moving writing element. The signal about the beginning of the recording area of the information coming from the recording unit 8 starts the converters 1, 2, 6 and 7. From this moment the information converter 1 at a time interval accumulates a pulse, the duration of which is proportional to the amount of information received at its input . n m 5 input information. The transducers 6 and 7 of the information in the label produce short pulses, the time between them and the signal of the beginning of the recording zone is proportional to the values of the information received at their inputs. The inputs of the information converter 2 in the time interval from the recording unit 8 also receive the signal of the end of the recording zone, and from the subtraction circuit 3 - the difference between the information about the width of the recording area formed by the encoder 4 the width of the recording area and the input information. Under the influence of these signals, the converter 2, triggered by the pulse of the beginning of the recording zone, produces a pulse whose duration is proportional to the information at the input of the subtraction circuit 3, and the end of the pulse coincides with the signal of the recording unit 8 about the end of the recording zone. Signals. From the outputs of converters 1, 2, b and 7, through logic unit 10 and modulator 9, the luminance arrives at the input of record unit 8, where during one scan cycle along the axis Y are fixed on the record carrier together with the signal of the beginning of the recording zone. Input impulses of converters 6 and. 7 and the start signal of the recording area are depicted as marks (dots). The output signal of the transducer 1 is depicted as a stroke, the beginning of which coincides with the mark of the beginning of the recording zone, the output signal of the transducer 2 also as a stroke, the xsz of which coincides with the end of the recording zone. The number of marks from the mark at the beginning of the recording zone and the length of the strokes is proportional to the values of the corresponding input information. Logic unit 10 is designed to process incoming pulses in order to minimize the number of media used on the recording medium without impairing the identification of the recorded information, which is especially necessary when using recording media with a low dynamic brightness range, such as electrothermal paper. The strokes on the record carrier have medium brightness (in Fig. 2, e | the area formed by strokes is reticulated), and the overlap interval of iprichs has an increased brightness (in Fig. 2-6, the area formed by overlapping areas of strokes is shown in plain black). The tags provided by converter 6 have increased brightness all the way. Yes, except when placed on a black background. Overlapping strokes where they are not depicted, i.e., represent white. The trace (in Fig. 2 b, the black line represents the combination of high brightness marks), the marks provided by the converter 7 are not depicted against the background of strokes (white trace), / have brightness in the zone of the absence of strokes

and in the black background of their overlap (in Fig. 21, the average brightness line is a combination of the average brightness points and is shown as a mesh). Designating A - the output signal of the converter 1; B - converter 2; With converter 6; D - converter 7, K and P - output signals of logic block 10, recorded on medium and high luminance media, respectively, make a table of input and corresponding output signals of block 10, with 1 in the "table corresponding to the signal level; About his absence; X is an indifferent state that K has at P 1, i.e., in the case when recording is performed with increased luminance, the presence or absence of a signal K, which provides medium luminance, does not matter.

Logical expressions for unit values of output functions K and P follow from the table.

to AVSb + ABC + ABCD + ABCD;

P ABCD ABCD + ABCD + ABCD + ABCD + ABCD + SBCD,

or after minimization in order to simplify the logical block

K ACD + BCD + A§D + ABC,

P ABCD + ABC + AC.

With the number of information converters in a label larger than two, for a reliable identification of processes it is necessary to use a larger number of luminance gradations, and the output functions of unit 10 are determined by the received image of information on the storage medium.

The information at the inputs of the recorder can be presented in the form of digital codes, analog values or in mixed form. Time and space information converters and into a label, a subtraction scheme and an encoder width of the recording area must correspond to the type of information on the corresponding inputs.

Stroke writing is preferable for recording parameters, the value of which varies dramatically between two adjacent sweep cycles along the Vi axis, and the dot recording is preferable for parameters that change slowly, for example, to record averaged parameters.
