Description

[Detailed Description of the Invention] This invention relates to a recording signal generating device that generates a recording signal for recording digital data from a data processing device such as an electronic computer with an analog recorder.

The digital data output by such a data processing device is of various types, that is, a tag number indicating which data it is, or a type of data, such as a measured value signal or a set value signal. Something is output.

When converting something like this into an analog signal and recording it on recording paper, it is difficult to see what is recorded on the recording paper and find out what kind of tag number it is or what type of data it is. difficult.

For this purpose, for example, in the case of a multi-pen type, it is possible to record in a different color for each pen and to correspond to the color and the name of the data, but the target data output to the pens may be changed on the data device side. If it is, it is impossible to identify it on the recording paper.

Alternatively, it is possible to record the data name corresponding to each pen on the data device side and read and recognize the data name using a terminal device such as a CRT display or printing device. In order to identify a record recorded by a single pen, it is necessary to memorize the entire history of its changes, and it is also difficult to associate the name with the record on the recording paper.

It is possible for the operator to manually write the name of the data corresponding to each pen on the recording paper, but this would place a heavy burden on the operator and cause errors; You cannot deal with this if you change the output.

The purpose of this invention is that when converting a signal output as digital data from a data processing device into an analog signal and recording it on a recorder, the attributes of the data, such as the data tag number and data type, are recorded on the recording paper It is intended to be able to record data as a pattern so that the data attributes of the recorded data can be known by looking at the records on the recording paper.

Therefore, in this invention, the attribute of data is stored in a register, and the register reads out the attribute image storage section to read out the image given to the attribute of the data, which is converted into a pattern signal by the pattern conversion section. .

The digital attribute pattern signal and the digital data are switched and taken out, and the output is converted into an analog signal and supplied to the analog recorder.

Next, an embodiment of the recording signal generating device according to this invention will be described with reference to the drawings.

This device is, for example, a data processing device 1 such as an electronic computer.
This device generates a recording signal for recording digital data from data processing device 11 with an analog recorder, and the digital data from data processing device 11 is temporarily stored in data register 12.

Further, the tag number indicating the attribute of the data input to the data register 12 is stored in the tag number register 13, and the data type code indicating the type of data is stored in the type register 14, respectively, by the data processing device 11.

On the other hand, the tag number image storage section 15 stores images for all tag number patterns, and similarly, the data type storage section 16 stores images for patterns indicating each data type.

These tag number storage unit 15 and data type storage unit 16 are attribute storage units, and are digital values that are images for generating pulse pattern sequences with different pulses and pulse widths depending on each tag number and data type. is memorized.

For example, as shown in FIG. 2, images representing each pattern are recorded in the storage units 15 and 16 as different patterns on the recording paper corresponding to each tag number and data type in the storage units 15 and 16. remembered.

This image is stored as a digital signal, and FIG. 2 shows it as a waveform.

These storage units 15.16 are connected to switches 17.1 according to the contents of the tag number register 13 and the data type register 14.
8 are selectively controlled, and images of corresponding numbers and data types are read out.

These read images are switched by a switch 19 and supplied to a pattern conversion section 21.

The pattern converter 21 converts the pulses into a series of pulses such that a pattern as shown in FIG. 2 is obtained.

The converted attribute pattern and the output of the data register 12 are switched by a switch 22 and supplied to a DA converter 23, whereupon they are converted into analog signals and supplied to an analog recorder 24.

These controls are performed by a sequencer 25.

When a new data recording request occurs in the data processing device 11, the tag number information of the data is set in the tag number register 13, the data type information is set in the data type register 14, and the data is set in the data register 15, respectively. A start command is sent to the sequencer 25.

The sequencer 25 receives this activation command and switches the switch 19.
After switching the switch 22 to the tag number image storage section 15 side and the switch 22 to the image pattern converter 21 side, the contents of the tag number register 13 are read out and the switch 17 is controlled according to the contents. The image pattern converter 21 reads out a more corresponding image.
supply to

This tag number image is converted into a digital pattern series, which is further supplied to the DA converter 23 through the switch 22, and then converted into an analog signal, which is supplied to the recorder 24.

When the conversion of the tag number image into a pattern signal is completed, this is detected by a timer inside the sequencer 25.

In other words, the generation time width of the tag number is determined to be constant, as shown by the pattern in FIG.

After converting the tag number image, the switch 19 is switched to the data type image storage section 16 side, and the contents of the data type register 14 are read out and the switch 18 is controlled accordingly, so that the image corresponding to the data type is The image pattern converter 21 is supplied with the image pattern converter 21 .

From this, a series of digital patterns is supplied to the DA converter 23 and output.

When this conversion is completed, the sequencer 25 switches to the switch 22.
is switched to the data register 12 side and the data is read out, and these data are converted into analog signals by the DA converter 23 and recorded by the recorder 24.

After this, data sent from the data processing device 11 is passed through the data register 12, continuously converted by a DA converter, and then supplied to the analog recorder 24.

As a result of this operation, the tag number TOO appears on the recording paper 26 near one side edge, as shown in FIG.
In the case of I, the corresponding pattern in FIG. 2 is recorded on the recording paper 26 as the pulse sequence pattern 27, and following this, if the data type is PV, that is, in the case of measured values, the data in FIG. 2 is recorded. A wide pulse as shown in the example of the type storage section 16 is recorded as the data type pattern 28.

Thereafter, the data from the data register 12 is recorded as a record 29.

After that, when the attribute of the data supplied from the data processing device 11 is changed, a pattern 27 indicating the tag number is used in the same manner.
Then, a pattern 28 indicating the data type is recorded, and data corresponding to the pattern 28 is recorded.

After the data record 29, attribute patterns 27 and 28 indicating the attributes of the data may be recorded.

As described above, according to the recording signal generator of this invention, the attributes of digital data are automatically recorded on the recording paper, so the type of the recorded data can be detected by the recording paper. 28, it can be determined without error by looking at the corresponding symmetrical clothing.
