Abstract

PURPOSE:To make the recording range readily readable ex post without separately providing a recording section for recording the recording range. CONSTITUTION:The measuring apparatus is such that the measured results are recorded in a recording paper 14 and the recording ranges are changed over to a plurality of stages. The apparatus comprises a recording signal outputting section 11 for outputting a measured-value recording signal corresponding to a relevant recording range that has been set in response to a measured-value signal corresponding to a measured result, and a measured-value recording section 13 for recording the measured-value recording signal on the recording paper in response to this recording signal. The recording signal outputting section 11 outputs a recording-range altering signal for recording a recording-range altering data 15 that relatively represents the post-alteration recording range by representing the alteration direction and stage number of the recording range, when the recording range has been altered. On the other hand, the measured-value recording section 13 records the recording-range altering data 15 on the recording paper 14 in response to the recording-range altering signal.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a measuring device, such as an exhaust gas analyzer, in which a measurement result is recorded on a recording paper and a recording range is switched among a plurality of stages.

[0002]

Some measuring devices of this type have a recording range that can be manually switched and a recording range that can be automatically switched.

In a measuring device in which the recording range can be manually switched, when the fluctuation of the measured value is large, a person is on during the measurement, and the recording range is switched according to the fluctuation of the measured value.
It is necessary to write down the recording range on the recording paper each time it is changed. Therefore, it is impossible to deal with it without a person in charge, and the work is troublesome.

In the measuring device in which the recording range is automatically switched, it is necessary to consider later on which range the recording paper and the other material have been changed. In this case, in addition to recording the measurement results, it may be possible to record the set recording range at all times.
In addition to the recording unit for recording the measurement result, a recording unit for recording the recording range is additionally required, which increases the cost of the device.

The object of the present invention is to solve the above problems,
It is an object of the present invention to provide a measuring device that allows the recording range to be easily determined later without separately providing a recording unit for recording the recording range.

[0006]

A measuring device according to the present invention is a measuring device in which a measurement result is recorded on a recording paper and a recording range is switched to a plurality of stages, and which receives a measurement value signal corresponding to the measurement result. The recording signal output section outputs a measured value recording signal corresponding to a set recording range, and the measured value recording section receives the measured value recording signal and records it on a recording sheet. When the recording range is changed, the unit outputs a recording range change signal for recording recording range change information that represents the changed recording range absolutely or relatively, and the measured value recording unit, Upon receiving the recording range change signal, the recording range change information is recorded on the recording paper.

[0007] For example, the recording range change information relatively indicates the changed recording range by indicating the direction and the number of steps of changing the recording range.

The recording range may be manually switched.

In addition, the recording signal output section may automatically change the recording range in accordance with the measured value signal. In this case, for example, the recording signal output unit outputs the measured value signal of 9 of the full scale of the current recording range.
When it becomes larger than 0%, it is changed to the recording range one step up, and when the measured value signal becomes smaller than 85% of the full scale of the recording range which is one step lower than the current recording range, it is recorded one step lower. It is made to change to the range.

[0010]

When the recording range is changed, the recording range change information indicating the changed recording range is recorded on the recording paper. Therefore, by looking at the recording paper later, the recording range of each portion can be easily known, and it becomes unnecessary to check the contents of the recording range change with another material. Further, only when the recording range is changed, the recording range change information is recorded by the measurement value recording unit for recording the measurement result, and it is not necessary to separately provide a recording unit for constantly recording the recording range.

[0011]

Embodiments of the present invention will be described below with reference to the drawings.

When the recording range is changed, 1) outputs a recording range change signal for recording the recording range change information (15) representing the changed recording range to the recording unit (13). In this example, the recording range change information (15) indicates the change direction of the recording range (whether it is changed to the upper stage or the lower stage) and the number of stages, thereby making the changed recording range relative to each other. It is supposed to be expressed.

The recording unit (13) of the recorder (12) normally receives the measured value recording signal from the recording signal output unit (11) and records it on the recording paper (14).

As shown in FIG. 2, the recording range change information (15) in the case of one-step range up includes one U-shaped portion (19). As shown in FIG. 3, the recording range change information (16) for the two-step range up includes two U-shaped portions (19). In this case, the left U-shaped portion (19) is included. ) 3rd straight line part
(19c) and the first straight portion (19a) of the U-shaped portion (19) on the right side are

It is composed of a long third straight line portion (20c) extending downward from the right end of the two straight line portion (20b) to the zero level L0. As shown in FIG. 4, the recording range change information (17) in the case of the one-step range down includes one inverted U-shaped portion (20). As shown in FIG. 5, the inverted U-shaped portion (20) is 2 in the recording range change information (18) in the case of 2-step range down.
In this case, the third straight portion (20c) of the left inverted U-shaped portion (20) and the first straight portion (20a) of the right inverted U-shaped portion (20) overlap each other. ing. The same applies to the case of range down of three or more steps.

Next, referring to the flowchart of FIG.
An example of the operation of the recording signal output unit (11) will be described.

When the measurement is started, first, appropriate initialization such as setting the number of the old range stages is performed (step 1). The old range step number represents the recording range before change, and is initially set to the step number of the recording range set by manual operation, for example. Also, the number of old range stages is updated when the recording range is changed and the processing is finished, as described later. When initialization is completed,
A measurement value signal is input from the detection unit (10) (step 2). Next, the recording range is automatically set based on the measured value signal (step 3). For this,
An example will be described later. Next, the number of stages of the set recording range is set to the new number of stages (step 4), and the measured value recording signal value is calculated based on the set recording range and the measured value signal (step 5). And recording unit (13)
Is output (step 6), the process returns to step 2, and the above operation is repeated.

An example of the output to the recording unit (13) in step 6 is shown in the flowchart of FIG.

In FIG. 7, first, the difference between the number of new range stages and the number of old range stages is calculated and set to C (step
601) and the value of C are checked (step 602). Step 60
If the value of C is 0 in step 2, the process proceeds to step 603, the measured value recording signal is output, and the process ends. If the value of C is positive in step 602, the process proceeds to step 604 and a full level signal is output. Next, (C-1) is set to C (step 605) and a zero level signal is output (step 606). Next, a timer process of waiting for a predetermined time set in advance is performed (step 607) and a full level signal is output (step 608). Next, the value of C is checked (step 609). If the value is positive, the process returns to step 605 and the above operation is repeated. If the value of C is 0 in step 609, the process proceeds to step 610, the new range stage number is set to the old range stage number, and the process ends. Step
If the value of C is negative in 602, the process proceeds to step 611 and a zero level signal is output. Next, (C + 1) is changed to C
Is set (step 612) and a full level signal is output (step 613). Next, the same timer processing as described above is performed (step 614) and a zero level signal is output (step 615). Next, the value of C is checked (step 616). If the value is negative, the process returns to step 612 and the above operation is repeated. If the value of C is 0 in step 616, the process proceeds to step 617, the new range stage number is set to the old range stage number, and the process ends.

If the recording range is not changed in step 3 of FIG. 6, the new range step number and the old range step number are the same, so the value of C calculated in step 601 of FIG. Proceed from 602 to step 603.
Then, while the number of recording steps is not changed, steps 601, 60
The measurement values are continuously recorded by repeating steps 2 and 603 and outputting the measurement value recording signal in step 603. This corresponds to the portion (A) in FIGS.

Immediately after the recording range is increased in step 3 of FIG. 6, the number of new range steps set in step 4 is larger than the number of old range steps.
The value of C calculated in step 601 becomes positive, and the process proceeds from step 602 to step 604. By outputting the full level signal in step 604 and the zero level signal in step 606, the first U-shaped portion (19) of the recording range change information (15) (16) in FIG. 2 or FIG. 3 is output. A straight part (19a) is drawn. Following this, the steps
By waiting a certain time at 607, the second straight line portion (19b) of the U-shaped portion (19) is drawn on the zero level L0. Further subsequently, in step 608, the full level signal is output to draw the third straight line portion (19c) of the U-shaped portion (19), thereby drawing one U-shaped portion (19). . In the case of one-step range up, the value of C calculated in step 601 is 1, and as described above, step 604
~ When step 608 is executed to draw one U-shaped portion (19) and then the process proceeds to step 609, C is changed from 1 to 0 in step 605, so after executing step 610, the process is executed. finish. This makes it possible to
As shown in (B), the recording range change information (15) indicating that the U-shaped portion (19) has one step range up is recorded, and in step 610, the new range step number is set to the old range step number, Since these are the same, steps 601, 602 and 603 are repeated until the recording range is changed next, and the recording of the measured value is continued as shown in the portion (C) of FIG. In the case of 2-step range up, the value of C calculated in step 601 is 2, and as described above, step 60
4 ~ Step 608 is executed once and the first U-shaped part (1
When the process proceeds to step 609 after drawing 9), since C has changed from 2 to 1 in step 605, the process returns to step 605, and steps 605 to 608 are executed once again and the second U The letter part (19) is drawn. As described above, when Step 605 to Step 608 are executed once again and the second U-shaped portion (19) is drawn and then Step 609 is reached, C is changed from 1 to 0 in Step 605. After executing step 610, the process ends. As a result, as shown in the portion (B) of FIG. 3, the recording range change information (16) indicating that the U-shaped portion (19) has two two-step range up is recorded, which is the same as the case of the one-step range up. , The part of Fig. 3 (C) until the recording range is changed next time
Recording of the measured value is continued as shown in FIG. In the case of a range increase of 3 steps or more, similarly to the above, after the recording range change information including the same number of U-shaped portions as the number of steps of the range increase is recorded, the measurement value is recorded until the next recording range is changed. Can be continued.

Immediately after the recording range is downed in step 3 of FIG. 6, the new range step number set in step 4 is smaller than the old range step number.
The value of C calculated in step 601 becomes negative and the process proceeds from step 602 to step 611. The zero level signal is output in step 611, and the full level signal is output in step 613, so that the inverted U-shaped portion (20) of the recording range change information (17) (18) in FIG. 4 or 5 is output.
The first straight line portion (20a) of is drawn. Following this, the second straight portion (20b) of the inverted U-shaped portion (20) is drawn on the full level LF by waiting for a certain time in step 614. Furthermore, subsequently, in step 615, the zero level signal is output, so that the third portion of the inverted U-shaped portion (20) is
A straight line part (20c) is drawn, whereby an inverted U-shaped part (20)
Is drawn. If the range is down by one step, step 60
The value of C calculated in 1 is -1, and when step 611 to step 615 are executed to draw one inverted U-shaped portion (20) and then step 616 is followed, step 612 is executed. Since C has changed from -1 to 0 in step 1, the processing is terminated after executing step 617. This allows
As shown in part (B) of FIG. 4, the inverted U-shaped part (20) has one recording range change information (17) indicating a one-step range down, and is recorded next as in the case of range up. Recording of the measured values is continued until the range is changed, as shown in part (C) of FIG. In the case of the two-step range up, the value of C calculated in step 601 is -2, and as described above, steps 611 to 615 are executed once and the first inverted U-shaped portion (20) is When the process proceeds to step 616 after drawing, since C has changed from -2 to -1 in step 612, the process returns to step 612, steps 612 to 615 are executed once again, and the second reverse U Character part (2
0) is drawn. Thus steps 612 to 615
Is executed once more to draw the second inverted U-shaped portion (20), and when the process proceeds to step 616, step 617 is executed because C is -1 to 0 in step 612. After that, the process ends. This makes it possible to
As shown in (B), the inverted U-shaped portion (20) is recorded with the recording range change information (18) indicating two two-step range down.
Similar to the case of stepped range down, the recording of the measured value is continued until the recording range is changed next, as shown in part (C) of FIG. In the case of range down of three steps or more, similarly to the above, after the recording range change information including the same number of inverted U-shaped parts as the number of steps of range down is recorded, the measured value is changed until the next recording range is changed. Recording continues.

In this case, the recording range is automatically set according to the measured value signal, and when the recording range is changed, the measured value recording section (13) indicates the recording range indicating the direction of change and the number of steps. Change information is recorded. Also,
The recording range at the start of measurement can be easily known later by setting the recording range set by the manual operation as described above. Alternatively, at the start of the measurement, it is possible to set the number of steps in a predetermined predetermined recording range or to adopt another suitable method so that it can be easily understood later. Therefore, the recording range of each portion can be easily known by tracing the recording range change information of the recording paper later. Therefore, there is no need for a person to be on the side during the measurement, and full automation of the measurement is possible.

An example of automatic setting of the recording range in step 3 of FIG. 6 is shown in the flowchart of FIG.

In FIG. 8, first, it is checked whether or not the current recording range is the highest (step 301). If not, the process proceeds to step 302, and the measured value signal and the full scale 90 of the current recording range are detected. Calculate the% difference and set this to D. Next, the value of D is checked (step 303
), If this is positive, the process proceeds to step 304, the recording range is increased by one stage, the number of stages is set to one stage higher than the present, and the process proceeds to step 305. When the current recording range is the highest in step 301 and step 30
When the value of D is not positive in 3, the process proceeds to step 305 as it is. In step 305, it is checked whether or not the current recording range is the lowest, and if so, the processing is ended. If the current recording range is not the lowest in step 305, the process proceeds to step 306, the difference of 85% of the full scale of the measured value signal and the recording range one step lower than the present is calculated, and this is set to E. . Next, the value of E is checked (step 307), and if it is not negative, the process ends. If the value of E is negative in step 307, the process proceeds to step 308, the recording range is lowered by one step, and
The number of steps is set to one step lower than the current one, and the process ends.

By performing the processing as shown in FIG. 8, when the measured value signal becomes larger than 90% of the full scale of the current recording range, and if there is an upper recording range, the next higher step (the number of steps is If the recording range is changed to a recording range that is 1 larger and there is a lower recording range, the measured value signal is 85% of the full scale of the recording range that is one step lower than the present (the number of steps is one less).
When it becomes smaller, it is changed to the recording range one step lower. In this case, the recording range is changed step by step. However, depending on the magnitude of the measurement value signal, the recording range can be automatically set such that the recording range is changed in two or more steps at a time.

In the above embodiment, the recording range is automatically set, but it is also possible to manually switch the recording range due to the presence of a person during the measurement.

An example of the operation of the recording signal output unit (11) when the recording range is manually switched in this way is shown in the flowchart of FIG.

In this case, the recording signal output section (11) can detect the manually set recording range by an appropriate means. Then, in step 3 of FIG. 9, the manually set recording range is detected and used as the set recording range. The contents of the other steps in FIG. 9 are the same as the contents of the same number of steps in the flowchart of FIG. In this case, the recording range is switched manually, but since the recording range change information is automatically recorded when the recording range is switched, it is not necessary for a person to write the recording range on the recording paper.

The recording range change information is not limited to that in the above embodiment, but can be changed as appropriate. When the recording range change information relatively indicates the changed recording range as described above, the changing direction and the number of steps are not limited to those described above. Further, the recording range change information may absolutely represent the changed recording range, for example, by the number of lines.

In the above embodiment, the case where the recorder (12) has one measurement value recording section (13) is shown, but the present invention is also applicable to the case where the recorder has two or more measurement value recording sections. Applicable. In this case, it is possible to record the recording range change information for all of the measurement value recording sections whose recording ranges can be switched, or to record the recording range change information only for the necessary measurement value recording section. You can also

According to the measuring apparatus of the present invention, as described above, the recording range can be easily known later without using a recording section for recording the recording range, and the recording range can be obtained from another material. Eliminates the need to investigate changes.
