Abstract

PURPOSE:To visualize continuously data even in case the data are brought into contact with graduation lines, etc., by discriminating whether the data are brought into contact with the graduation lines or not and prohibitting to record the graduation lines, etc., of a discriminated contact part. CONSTITUTION:The measured data by detectors 1 and 2 are taken in a CPU 5 via a multiplexer 3 and an A/D converter 4 and stored in a memory 6 in order of the sampling time to be taken in. Further, the measured data taken in under control of the CPU 5 are data-recorded with a color thermal copy print part 7 and at the time of recording it, the graduation lines and further, a time axial line at the necessary timing are also recorded. Then, the CPU 5 compares the measured data (data of channels I and II) from the detectors 1 and 2 with a level of each graduation line for every channel and discriminates whether the measured data are brought into contact with the graduation lines, etc., or not. Then, in case the CPU 5 discriminates that the measured data are not brought into contact with the graduation lines, it records both the data of each channel and the graduation lines and in case the CPU 5 discriminates that the measured data are brought into contact with the graduation lines, it records the channel data of the contact part and does not record the graduation lines.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application This invention relates to a recorder, especially a multicolor two-dimensional display means, that records not only data but also scale lines and time axis lines. Regarding the meter.

(b) Prior Art Recorders well known in the art include pen type recorders and dot type recorders. In any case, these are chart paper C on which scale lines a and time axis lines are drawn in advance, as shown in
It records data continuously. These recorders require special chart paper each time the type of measurement data changes, so in recent years recorders that record data along with scale lines and time axis lines on blank chart paper have become popular. It is being considered.

(c) Problems to be Solved by the Invention In recorders that record data, scale lines, and time axis lines on a blank chart paper, for example, as shown in Figure 5, trend recording (data recording) is required. If line A and scale line B touch each other continuously, even if the colors of trend record A and scale line B are different, because the same quality of ink is used, due to human optical illusion, a straight line will appear better. There was a problem in that it was emphasized and visually observed, making the trend record appear to have disappeared.

SUMMARY OF THE INVENTION An object of the present invention is to provide a recorder in which trend records can be visually viewed continuously even when trend records and scale lines come into contact with each other.

(d) Means and operation for solving the problems The recorder of the present invention records not only time-sequential data but also scale lines and time axis lines on a multicolor two-dimensional display and recording means. Discrimination means (Sr2, Sr3.5T7) that determines whether or not data and scale lines, etc. come into contact; and recording prohibition means (Sr8, Sr8, Sr1.5TIO).

In this recorder, when the determining means determines that the data line is in contact with one of the scale lines, the scale line is not recorded at the contact portion, but only the data line is recorded.

Note that the term "contact" here includes cases where the drawing lines completely overlap.

(E) Examples The present invention will be explained in more detail with reference to Examples below.

FIG. 2 is a block diagram of a recorder in which the present invention is implemented. In this recorder, measurement data from two detectors 1.2 is converted into a digital signal by an A/D converter 4 via a multiplexer 3, and is input to a CPU (central processing unit) 5. The data are stored in the memory 6 in order of sampling time. Further, under the control of the CPU 5, the captured measurement data is trend-recorded in the color thermal transfer printing unit 7, and during the recording, scale lines and furthermore, time axis lines are also recorded at necessary timings.

The CPU 5 inputs the measurement data from the detectors 1 and 2 (hereinafter, the measurement data of the detector 1, the data of the channel
A function that compares the level of each scale line with the measured data of channel (referred to as the data of channel ■) and determines whether the measured data and the scale line contact each other, and if it is determined that they do not contact. , a function to record both the data and the scale line of each channel, and a function to record the channel data of the touching part but not record the scale line when it is determined that there is contact.

Next, the operation of the embodiment recorder will be explained with reference to the flowchart shown in FIG.

When the operation is started, the channel data from the detector 1.2 is sent to the multiplexer 3 and the A/D converter 4 at predetermined intervals.
through the CPU 5 and stored in the memory 6 (step 5TI). Then, it is determined whether the data of channel I and the scale line touch each other (step 5T2).
Now, as shown in Figure 3, channel ■
data NQ A-,, data line A2 of channel H
, furthermore, scale lines B3, B2, B3 are recorded, in step ST2, data line A1, scale line B,
, B, , B3 will be compared in level. Channel r data (scale &I B ,,B2.B:l
If they overlap or differ by 1 (for example, at time t2 in FIG. 3), it is determined that the channel I and the scale line are in contact with each other, and the process moves to step ST7. However, the channel ■

time), it is determined that they do not touch, and the process moves to step ST3, where it is determined whether or not the data of channel (2) and the scale line touch.

In this case, the data for channel H and the scale line B.

B2 and B3 are compared. As a result of the comparison, as at the 1° point in Fig. 3, the data line A2 of channel ■ also corresponds to the scale line B1.
, B2, B3, the scale line B7,
The current bones of B2 and B3 are written (step 5T4), and the current bones of data A1 and A2 of channel I and ■ are recorded (step 5T5). Unless the recording operation is finished (step 5T6), the process returns to step STI. , move on to the next processing cycle.

Then, data kA A 1. of channels ■ and ■. A
2 and any of the scale lines B1, B2, and B3, the processes of steps STI to ST6 are repeated, and as time passes, the data bl A l, A2 and the scale line B

Eventually, as illustrated in FIG. 3 (time tz), when the data line A of channel I and the scale line (B2) come into contact, the determination in step ST2 becomes YES, and in step ST7, the data line A of channel I A z Scale line B +, B
2. B If it does not touch any of 3, step S
The T7 scale is No, and in this case, the scale lines (B
, , B:l) are written (step 5T8), and all the data lines A+ and Az of channels I and H are recorded (step 5T5). In other words, the scale line (B
Only recording of 2) is prohibited. This prohibition of recording continues as long as contact with the data line continues.

Also, only data line A2 of channel H is scale line B +
, B z, B 3, the determination in step ST3 is YES, and the process moves to step 5TIO, where the scale lines excluding the scale line that is in contact with the data line A2 are recorded.In this case, of course, the data line A ,,A, are recorded.

Furthermore, the data of channel I, ■ km A 1. A
When z touches one of the scale lines, the determinations in steps ST2 and ST7 both become YES, and in this case, the data v! A1. Recording of each scale line touching A2 is prohibited (step 5T9).

In the above embodiment, the number of channels is 2 and the number of scales is 3.
However, this number is specified for convenience of explanation, and the present invention is not limited to these numbers.

Further, in the above embodiment, a color thermal transfer blink is used as the recording means, but the present invention can also be applied to the case where data, scale lines, etc. are temporarily recorded on a two-dimensional recording means such as a color CRT display.

(f) Effects of the Invention According to this invention, in data recording, that is, trend recording and recording of scale lines, etc., in the same recording method, when the trend record and the scale lines, etc. touch, the scale lines etc. Since the recording of the contact area is prohibited and only trend recording is allowed at the contact area, the trend recording is very easy to see.
