Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a data processing device, and more particularly to a data processing device that is optimal for displaying analog signal waveforms and scales on the same paper of a printing device.

Conventionally, a chromatographic data processing apparatus generally has a configuration in which a storage device and a printing device are combined. The storage device performs waveform processing on data using analog signals, performs calculations in accordance with the processing, and sends the calculation results to the printing device for printing. Therefore, there was a drawback that it was difficult to tell what the analysis results were just by looking at the printed results. Therefore, in order to know this, it was necessary to use a recorder that records analog signals in addition to the printing device. This resulted in two printed copies showing the results, and time was wasted organizing the data. Furthermore, two types of output devices are required, which increases the cost. Moreover, what is particularly unsatisfactory is that the recording paper of the recorder is limited, and paper with different scale display is used depending on the analyzer to be combined.

For this reason, there is an inconvenience in that a large number of recording sheets must be prepared for each type of analytical instrument. SUMMARY OF THE INVENTION An object of the present invention is to provide a data processing device that prints analog signal waveforms on paper with graduations.

The present invention uses a dot printing device to
Store analog signal waveforms such as chromatographs in the storage unit, rearrange the signal waveforms so that they can be easily printed,
Furthermore, in order to clarify the temporal changes in the signal waveform, a unit (positive number, logarithm, etc.) is used to indicate time and the magnitude of the signal.
A scale is created in the storage unit, and this signal waveform is printed on a blank printing paper with the scale and EO printed on the same page as the calculation results.

FIG. 1 is a block diagram showing an embodiment of the present invention.

The processing device 10 connects to the arithmetic device 12 via a bus line 11.
, memory elements 13 and 14, A/○ converter 15, printing device 1
6. The operating condition input devices 17 are connected to each other.

The analog signal from the signal source (output signal of the analyzer) 20 is sent to the A/D converter 15 and converted into a digital signal.

The digital signal converted here is sent to the arithmetic unit 12 via the bus line 11 and stored in the storage device (RAM) 14 after various processing. The contents processed by the arithmetic unit 12 are incorporated into the memory element (ROM) 13 as a program, and based on this content, the data stored in the memory element 14 is returned to the arithmetic unit 12 again for calculation.
The results are printed on the printing device 16 as necessary. Note that the processing conditions are input using the operating condition input device 17. The specific operation of the apparatus having the above configuration will be explained in detail with reference to the flowcharts of FIGS. 1 and 2.
The digital signal from the A/○ converter 15 input to the arithmetic unit 12 is input into a print buffer provided in the storage element 14 in order to draw a chromatogram.

This print buffer is provided with a data storage buffer as shown in FIG. Digital signals are sent here every moment. At this time, as shown in FIG. 3, new signal values are entered in the print data memo with the passage of time, and printing as shown by a curve 160 is performed. In addition, as shown in FIG. 3, the scale base line 161 obtained by calculation,
Each of the 50% scale and 100% scale is a target scale graduation in the present invention, and a positive number, a logarithmic scale, or the like can be displayed depending on the purpose of analysis.
The procedure for creating this scale will be explained with reference to the flowchart shown in FIG. In step a, data is collected, and in step b, the signal value (A/D) is read and stored in the data memory. Then, the process moves to step c, in which this value is matched (masked) with a predetermined scale value, and the data is arranged in a print buffer (step d). In step c, a constant corresponding to the unit of the scale to be printed is selected, and data for the same time period as the signal detection time is created. After step d, fill this print buffer with new data one after another while advancing the address in the buffer until the signal value is filled, and when this is filled, step e
Then, the data in the buffer is output as one shot amount (step f). This series of operations is repeated until the analysis is completed, and a chromatogram as shown in Figure 3 is drawn. At this time, a constant mark is made in advance in the print buffer, with the passage of time as the axis and the ratio representing the signal magnitude as the vertical axis. In other words, data is input in advance into the print buffer so that the maximum valid point of the blank print paper is set to 100% (on the right side when facing the print paper) and the opposite side is set to 0. Send digital signals. Therefore, in the buffer at this time, the zero level, which represents the unit of signal magnitude, the maximum full scale level, and the digital signal are simultaneously stored. The distribution of signals stored in the data storage buffer will be explained using FIG. The digital signal entered is first entered in the leftmost 0 column, and as the next signal is taken in, it is sequentially moved to the right column to receive the subsequent data signal. When the print buffer is filled with data signals in this manner, the printing device 16 of FIG. 1 prints data signals starting from the left side.

Further, the scale marker signal is a combination of signal data and pre-calculated and placed marker signal values, stored in a print buffer at the time of printing, and printed simultaneously with the data signal. Regarding the scale, it may be possible to change it depending on the content of the analysis.

For example, the full scale of the printed chart can be set to 1 V and the signal is attenuated depending on the magnitude of the signal, or it can be set to a logarithmic scale so that the peak cannot be exceeded, or the like can be changed depending on the purpose. The print buffer 5 shown in FIG. 3 is a buffer for one line of printing.
This shows the process of hitting the ball at times 0, 1, 2, 3, etc. Also, as shown in Fig. 3, time marker 1
65, marks are created by masking at regular intervals (for example, every minute).

If this continues until the end of the analysis, a chromatogram will be completed as shown in Figure 4. Of course, this scale can be drawn not only with positive numbers but also with a logarithmic scale depending on the purpose. In addition, what is printed at the bottom of FIG. 4 are the title and the processing results. In this way, in the past, the type of recording paper was changed depending on the purpose, but according to the embodiments of the present invention, one type of blank paper can be used for many types of purposes, which improves usage and maintenance. And it is extremely effective in terms of cost.

As is clear from the above, according to the present invention, a scale corresponding to the printed content can be printed on the same paper.
