Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method of displaying output data in the form of a graph on recording paper, and more specifically, the present invention relates to a method for displaying output data in the form of a graph on recording paper, and more specifically, it relates to a method for displaying output data on a recording paper using a printer attached to a measuring instrument such as a clamp wattmeter. The present invention relates to a method of displaying output data as a graph on recording paper when two types of output data, which are the results of processing measurement data, are output and displayed separately on paper as bar graphs.

[Prior Art] Some measuring instruments such as clamp wattmeters are equipped with a printer, and the printer can print output data obtained based on captured measurement data as a linear graph on recording paper and display the output. There are some things that look like this.

FIG. 5 shows an example of an output display on recording paper using a linear graph when the output data is of two types: current value and power value.

According to the figure, the recording paper 1 is located in the feeding direction for a predetermined period of time, for example, an integer from rlJ to "8" indicating a total of 8 hours divided into equal intervals of 1 hour. An X-axis 2 having a time scale number nearby and having a scale at a position corresponding to each time scale number, a Y-axis 3 on the starting end side and a Y-axis 4 on the end side with respect to this X-axis 2. It has a graph display area 5 divided by .

Among these, on the starting end side Y-axis 3, individual scale numbers indicating the electric power value (kW) located near the upper side are placed, for example, "lO
A scale corresponding to a scale number that is an integer multiple of "2" up to "2" is attached.

In addition, on the terminal side Y-axis 4, there is a scale corresponding to individual scale numbers indicating the current value (A) located near the lower side, for example, scale numbers corresponding to integral multiples of "10" up to "50". It is attached.

In the graph display area 5 partitioned on the recording paper 1 in this way, the power value (kW), which is one output data, is displayed.
is the thin line graph 6, and the current value (A
) are printed in the X-axis direction on a thick line graph 7 for each unit time, and the previous and current output data are connected via a connecting line 8 parallel to the Y-axis, forming a continuous step-like line. Graph 9. The output is displayed as IO.

FIG. 6 shows the linear graph 9.10 shown in FIG.
2 is a flowchart outlining the processing procedure for printing and output displaying.

According to the figure, the first data processing involves importing data from chi regarding power and performing data conversion processing to enable display as a thin line graph 6, and then importing data from ch2 regarding current and performing data conversion processing to enable display as a thin line graph 6. After performing data conversion processing to enable display as graph 7,
A graph for the first time is displayed on the recording paper 1.

For the second and subsequent data processing, after importing the chi data, compare the previous data, for example, if the current data processing is the second measuring instrument, with the first data. Data conversion processing is performed so that the data can be displayed as a thin line graph 6 parallel to the X-axis 2 at an appropriate position determined by the X-axis 2. The second and subsequent data processing for the ch2 is also performed in the same manner as for the chi.

In this way, each output data after completing the data conversion process is formed into a stepwise continuous linear form with a connecting line 8 interposed between the current data, which is the second data, and the previous data, which is the first data. The a force can be displayed as graphs 9 and 1o.

Thereafter, the output data on the recording paper 1 is displayed in the same way by displaying the linear graphs 9 and 1o up to the final time (in the illustrated example, the eighth time).

[Problem to be Solved by the Invention] By the way, when displaying two types of 8-point data as a linear graph 9.10 as shown in FIG.
As long as the data of and ch2 do not overlap, it is possible to easily compare the data with each other, and it is also easy to understand changes in each data value.

Moreover, the data of chi and ch2 are each represented by step-like linear graphs 9. ]o, so if you want to understand the measured value as a quantity, such as the amount of electricity, you can easily calculate the area.

However, when the output data of chi and ch2, which are linear graphs 9.10, overlap, it becomes difficult to compare the two, and the changes thereof also become unsightly.

Furthermore, in order to print out a step-like pattern linear graph 9.10 as shown in Figure 5, it is necessary to compare the previous data with the current data, and a separate program is required for this comparison process. There is also the problem that the process becomes complicated.

[Means for Solving the Problems] The present invention has been made in view of the above problems, and its structural feature is that the output can be stored based on measurement data taken into the measuring instrument body. Among the multiple types of output data, the selected two types of output data are:
X, which is a time axis of a predetermined length along the recording paper feeding direction
For a graph display area partitioned by an axis, a starting end side Y axis, and an ending side Y axis with respect to this X axis, one output data is a bar graph of the first pattern and the other output data is a bar graph of the first pattern. Two patterns of bar graphs are displayed in parallel in the Y-axis direction, making it possible to identify each data content, and the scale data necessary for the bar graph of one pattern is displayed in correspondence with the starting end side Y-axis, The scale data necessary for the bar graph of the pattern is arranged and outputted in correspondence with the Y-axis on the end side.

[Function] For this reason, among the multiple types of output data that can be stored in the main body of the measuring instrument, two types of specific output data that have been selected are displayed in a unit time relative to the graph display area of the recording paper. The data can be displayed in parallel as bar graphs that allow identification of each data content.

Also, the scale data required for one bar graph is the starting end side Y.
Based on the correspondence with the axis, the scale data necessary for the other bar graph is arranged in correspondence with the terminal side Y-axis, so the two types of specific output data for each unit time are The numerical value can be grasped using the bar graph and the scale data, and it is easy to compare the data in any case. Since the data can be output and displayed without performing the comparison process, it is possible to simplify the creation of a program for data processing.

[Example] Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 3 shows a schematic configuration of the printer section 11 attached to the main body of a measuring instrument such as a clamp wattmeter used for carrying out the present invention, and FIG. 4 shows a diagram corresponding to each of these components. FIG. 2 is an explanatory diagram showing the functions of each block.

In other words, measurement data such as current and voltage taken into the measuring instrument body through the input terminal undergoes necessary data processing such as performing necessary calculations to obtain the power value as output data. /D converter to convert into multiple types of output data and store it, and two types of output data selected from these multiple types of output data are c
The output data is divided into hi output data and ch2 output data and introduced into the printer section 11 shown in FIG. 3.

Two types of output data identified in this way, for example, power data (kW) which is the output data of chi and ch2
The printer unit 11 into which the current data (A) which is the output data of is introduced includes a RAM 12, a CPU 13 including a counter 13d, a RAM 14, a drive circuit 15,
It is configured to include at least a printer 16 for printing on recording paper 21.

Of these, the RAM! 2 stores various data such as graph item data regarding a bar graph pattern determined in relation to the two types of output data introduced and each output data of ch1 and ch2.

Further, the CPU 1.3 stores various data stored in the RAM 12, for example, if the stored data is graph item data, the CPU 1.3 generates a scale number unique to the output data corresponding to this graph item data, and a scale number specific to the output data corresponding to this graph item data. A scale data creation processing means 13a for creating specific scale data such as corresponding units (for example, rkWJ, rAJ, etc.), and if the stored data is output data of chl and ch2, these correspond to the numerical values. In addition to serving as a graph data conversion processing means 13b for converting into specific graph data, it also functions as a print data transfer unit for transferring scale data, graph data, etc. stored in the RAM 14 as print data. It also functions as a processing means 13c.

Note that the RAM 14 includes the scale data creation processing means 13.
It stores scale data created through step a, graph data converted through graph data conversion processing means 13b, and the like.

FIG. 1 is a flowchart showing the processing procedure of the method of the present invention carried out via the printer unit 11 having such a configuration.

In this case, multiple types of output data, such as power data and current data, as well as active power, reactive power, apparent power, and Data showing rates, etc.
Appropriate two types of output data are selected from among the output data that can be output.

After the two types of output data are specified in this way, a series of processes for printing out graph data corresponding to each of these output data is started.

That is, for the recording paper 21 installed in the printer 16 of the printer section 11, first, the RA, M1
The graph item data is read from 2, and scale data is created via the scale data creation processing means 13. This is stored in the RAM 14, which is a scale data memory, and is sent as print data via the print data transfer processing means 13c. Then, the scale data is printed on the recording paper 21 by the printer I6. The scale data at this time is the recording paper 21.
In addition to explaining and displaying the relationship between the graph pattern and the output data in the graph item explanation display column 22, the scale numbers corresponding to one specific output data, for example, the power data as the output data of chi, are the starting end side Y-axis layer scale numbers. Display column 2
6, and furthermore, the scale 2 corresponding to this scale number
8 is printed on the starting end side Y-axis 27.

In this way, after the required scale data has been printed on the recording paper 21, the X-axis 23, which is a time axis of a predetermined length along the sending direction, and Graph data is printed out in a graph display area 32 defined by the starting end side Y-axis 27 and the ending end side Y-axis 29, which will be described later.

In this case, the printout is performed by dividing the X-axis 23 evenly and displaying one of the output data for each unit time displayed in the X-axis scale numeric display field 26, for example, the power data of chi, and displaying the graph item explanation. In column 22, a first pattern of bar graphs, for example, a white bar graph 33, is displayed, and the other output data, for example, ch2 current data, is displayed as a second pattern of bar graphs, for example, a black bar graph 34, so that they can be identified from each other. They are displayed in parallel.

Display of the bar graphs 33 and 34 in this case is executed by following the steps below.

That is, first, the RAM 12 which is chl data memory
The power data as the output data of the chl for a unit time, for example, one hour, is taken in from , and is converted into graph data corresponding to the bar graph 33 of the white pattern via the graph data conversion processing means 13b, After storing it in the RAM 14, which is the graph data memory, the current data, which is the output data of ch 2, is similarly taken in from the RAM 12, which is the ch 2 data memory, and is converted into graph data corresponding to the bar graph 34 with the black background pattern. and stores it in the RAM 14, which is a graph data memory. Next, the graph data for the unit time is taken into the graph data memory RAM 14, transferred via the print data transfer processing means 13c, and the bar graph 33 for the unit time is printed on the recording paper 21 by the printer 16. It is printed as 34.

(Then, by repeating the same printing process while sequentially counting down the number of data set in advance in the counter 13d, all the output data for each unit time is printed as bar graphs 33 and 34 with different patterns. Ru.

In this way, all the series of output data are printed on the recording paper 21.
After the terminal side Y-axis 29, which has a scale 30 corresponding to the other specific output data, for example, the current data that is the output data of ch2, is printed, the terminal side Y marine The scale numbers to be displayed in the scale number display column 31 are printed, and the entire process is completed.

Since this invention is configured as described above,
Of the multiple types of output data stored in the measuring instrument body, for the two selected types of specific output data, each data content can be identified for each unit time in the graph display area 32 of the recording paper 2I. Bar graphs 33, 34,
For example, the power data that is the output data of chl can be displayed in a bar graph 33 with a white pattern, and the current data that is the output data of ch2 can be displayed in parallel as a bar graph 34 with a black background pattern.

In addition, the scale data such as scale numbers necessary for one of the bar graphs 33 or 34 is based on the correspondence with the starting end side Y-axis 27.
The scale data such as scale numbers necessary for the other bar graph 34 or 33 can be arranged in correspondence with the terminal Y-axis 29 and output and displayed in their entirety on the recording paper 21.

Therefore, the two types of specific output data can be directly read as bar graphs 33 and 34 with different patterns, which not only makes it easy to compare the data, but also allows you to compare the previous data and current data for each unit time. Since output and display can be performed without performing comparison processing with data, it is possible to simplify the creation of programs for data processing.

[Effects of the Invention] As described above, according to the present invention, two types of specific output data selected from among a plurality of types of output data stored in the measuring instrument main body are displayed in the graph display area of the recording paper. The scale data required for one bar graph can be displayed in parallel as a bar graph in which the data contents can be identified for each unit time, and the scale data required for one bar graph is The scale data required for the graph is on the terminal side Y
By arranging them in correspondence with the axes, the entire arrangement can be output and displayed on recording paper.

Therefore, the values of the two types of specific output data can be read from each bar graph, which not only makes it easy to compare the data, but also outputs the data without having to compare the previous data and current data for each unit time. Since the information can be displayed, it is possible to simplify the creation of programs for data processing.
