Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of displaying output data in a graph on a recording paper, and more particularly, to a method of recording by 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 processing results of measurement data, are separately output and displayed as bar graphs on paper.

[Prior Art] A measuring instrument such as a clamp wattmeter is provided with a printer, and output data obtained based on the acquired measurement data can be printed as a linear graph on a recording paper by the printer and output and displayed. There is something like that.

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

According to the drawing, the recording paper 1 is positioned in the sending direction and is divided for a predetermined period of time, for example, one hour at regular intervals, from "1" to "8" indicating a total of eight hours. X-axis 2 having a time scale numeral in the vicinity thereof, which is an integer, and having a scale at a position corresponding to each time scale numeral.
And a graph display area 5 defined by a start end Y axis 3 and an end Y axis 4 with respect to the X axis 2.

Of these, the starting end side Y-axis 3 has individual scale numbers indicating the power value (kW) located near the upper side thereof, for example, “10”.
Scales corresponding to scale numbers that are integral multiples of "2" are provided.

Also, on the terminal side Y-axis 4, individual scale numbers indicating the current value (A) positioned near the lower side thereof, for example, scales corresponding to scale numbers of an integral multiple of "10" up to "50". Is attached.

In the graph display area 5 partitioned and formed on the recording paper 1 in this manner, the power value (kW) as one of the output data is provided.
Is a thin line graph 6, and the other output data, the current value (A), is printed in a bold line graph 7 in the X-axis direction for each unit time.
These are connected via a connection line 8 parallel to the axis, and are output and displayed as continuous stepwise linear graphs 9 and 10.

FIG. 6 is a flowchart showing an outline of a processing procedure when the linear graphs 9 and 10 shown in FIG. 5 are printed on the recording paper 1 and output and displayed.

According to the figure, in the first data processing, the data conversion processing is performed so that the data can be displayed as the thin line graph 6 by taking in the data of ch1 for the power, and then the data processing can be performed by taking in the data of ch2 for the current and the thick line. Graph 7
After performing the data conversion process so as to enable the display as, the graph display for the first time is performed on the recording paper 1.

In the second and subsequent data processing, after the data of ch1 is acquired, the data for the previous time, for example, when the data processing for the current time is the second measurement, the data is compared with the data for the first time. A data conversion process that can be displayed as a thin line graph 6 parallel to the X-axis 2 is performed at an appropriate position determined as described above. The data processing for the second and subsequent times for the ch2 is also the same as the above c.
This is done in the same way as for h1.

Thus, each output data after the completion of the data conversion process is a linear continuous line in a stepwise manner with the connecting line 8 interposed between the present data as the second time and the previous data as the first time. It can be output and displayed as graphs 9 and 10.

Thereafter, the linear graphs 9 and 10 are displayed in the same manner up to the last time, in the illustrated example, up to the eighth time.
Is displayed.

[Problems to be Solved by the Invention] When two types of output data are displayed as linear graphs 9 and 10 as shown in FIG.
As long as the data does not overlap with each other, the data can be easily compared with each other, and the change in each data value can be easily grasped.

In addition, since the data of ch1 and ch2 are displayed as staircase linear graphs 9 and 10, respectively, if it is desired to grasp the measured value as an amount such as electric power, for example, it is necessary to easily calculate the area thereof. Can be.

However, when the output data of ch1 and ch2, which are the linear graphs 9 and 10, overlap with each other, it is difficult to compare both, and there is a disadvantage that the change becomes difficult.

Further, in order to print as linear graphs 9 and 10 having a step-like pattern as shown in FIG. 5, a comparison process between the previous data and the current data is necessary, and a separate program for this comparison process is required. Has to be created, and there is a problem that the operation becomes complicated.

[Means for Solving the Problems] The present invention has been made in view of the above problems,
The feature of the configuration is that, based on the measurement data taken into the measuring instrument main body, two types of output data selected from among a plurality of types of output data that can be output are stored in a recording paper sending out. For each X-axis, which is a time axis of a predetermined length along the direction, and a graph display area defined by a starting Y-axis and an ending Y-axis with respect to the X-axis, one output data is output for each unit time. In the bar graph of the first pattern, the other output data is displayed in parallel in the Y-axis direction by enabling the identification of each data content in the bar graph of the second pattern, and the scale data required for the bar graph of one pattern is Under the correspondence with the starting end Y-axis, the scale data required for the bar graph of the other pattern is arranged and output and displayed in correspondence with the end Y-axis.

[Operation] For this reason, of the two types of specific output data selected from the plurality of types of output data stored in the measuring instrument main body so that the output is possible, the unit time is displayed in the graph display area of the recording paper in unit time. Each data can be displayed side by side as a bar-shaped graph that allows identification of each data content.

The scale data required for one bar graph is arranged in correspondence with the starting Y axis, and the scale data required for the other bar graph is arranged in correspondence with the end Y axis. So, the two types of specific output data per unit time are:
In each case, the numerical value can be grasped by the bar graph and the scale data. In any case, the comparison work of the data can be easily performed, and the previous data and the current data for each unit time can be compared. Can be output and displayed without performing the comparison processing, so that the creation of a program for data processing can be simplified.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 3 shows a schematic configuration of a printer unit 11 attached to a measuring instrument main body such as a clamp wattmeter used in the embodiment of the present invention, and FIG. FIG. 4 is an explanatory diagram showing functions of respective blocks.

That is, the measurement data such as current and voltage taken into the measuring instrument main body via the input terminal is subjected to necessary data processing such as performing necessary calculations to obtain a power value as output data, and A The output data is converted into a plurality of types of output data via the / D converter and stored, and two types of output data selected from the plurality of types of output data are stored in the ch.
The output data is divided into the output data of 1 and the output data of ch2 and is introduced into the printer unit 11 shown in FIG.

The printer unit 11 into which the two types of output data specified in this way, for example, the power data (kW) that is the output data of ch1 and the current data (A) that is the output data of Hc2 are introduced, a RAM 12, CPU 13 with counter 13d, RAM 14
, A drive circuit 15, and a printer 16 for printing on the recording paper 21.

Among them, the RAM 12 stores various data such as graph item data of a bar graph pattern defined in relation to the two types of output data introduced, and each output data of ch1 and ch2.

Further, the CPU 13 stores various kinds of data stored in the RAM 12, for example, when the stored data is graph item data, scale numbers specific to output data corresponding to the graph item data, and corresponds to the scale numbers. Scale data creation processing means 13a for creating specific scale data such as a unit (for example, "kW" or "A"),
If it is the output data of h1 and ch2, in addition to being in charge of the function as a graph data conversion processing means 13b for converting these into specific graph data corresponding to the numerical values, the scale stored in the RAM 14 It is also in charge of a function as print data transfer processing means 13c for transferring data, graph data, and the like as print data.

The RAM 14 stores scale data created through the scale data creation processing means 13a and graph data converted through the graph data conversion processing means 13b.

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

In this case, in addition to a plurality of types of output data obtained by calculating measurement data about the voltage and current taken into the measuring instrument body, for example, in addition to power data and current data,
Appropriate two types of output data are selected from output data that can be output, such as data indicating active power, reactive power, apparent power, power factor, and the like.

After the two types of output data are identified in this way,
A series of processes for printing and outputting the graph data corresponding to each of these output data is started.

That is, with respect to the recording paper 21 provided in the printer 16 of the printer unit 11, first, the graph item data is read from the RAM 12, and the scale data is created through the scale data creation processing means 13. The data is stored in the RAM 14 as a data memory, transferred as print data via the print data transfer processing means 13c, and the recording paper 21 is printed by the printer 16.
The scale data is printed on. As the scale data at this time, in addition to displaying and explaining the relationship between the graph pattern and the output data in the graph item explanation display column 22 on the recording paper 21, one specific output data, for example, corresponding to the power data as the output data of ch1 The scale number to be displayed is displayed in a scale number display field 26 for the start side Y axis, and further, a start side Y axis 27 provided with a scale 28 corresponding to the scale number is printed.

In this manner, the recording paper 21 after the required scale data is printed is provided with an X-axis 23 which is a time axis having a predetermined length along the sending direction and the X-axis 23. Graph data is printed out in a graph display area 32 defined by the start end Y axis 27 and the end Y axis 29 described later.

In this case, first, the output data, for example, the power data of ch1, for each unit time displayed in the X-axis scale numeral display field 26 by dividing the X-axis 23 equally, is already displayed in the form of a graph item. In the column 22, a bar graph of the first pattern, for example, a white bar graph 33 of an outline, and the other output data, for example, the current data of ch2, can be mutually identified as a bar graph of the second pattern, for example, a bar graph 34 of a black background. Each is displayed in parallel.

The display of the bar graphs 33 and 34 in this case is executed according to the following procedure.

That is, first, power data as output data of ch1 for a unit time, for example, one hour, is fetched from the RAM 12 which is a ch1 data memory, and is output through the graph data conversion processing means 13b as a bar graph of a white pattern. After converting to graph data corresponding to 33 and storing it in RAM 14 which is a graph data memory, the current data which is the output data of ch 2 is similarly loaded from RAM 12 which is a ch 2 data memory, and corresponds to a bar graph 34 of a black background pattern The data is converted into graph data and stored in a RAM 14 serving as a graph data memory. Next, the graph data for the unit time is fetched from the RAM 14 serving as the graph data memory, transferred via the print data transfer processing means 13c, and printed as a bar graph 33, 34 for the unit time on the recording paper 21 by the printer 16. Is done.

Thus, by repeating the printing process in the same manner while sequentially counting down the number of data previously set in the counter 13d, all output data per unit time are printed as bar graphs 33 and 34 having different patterns.

In this way, all of the series of output data
After the output is displayed and printed, the other specific output data, for example, after the end side Y-axis 29 provided with the memory 30 corresponding to the current data that is the output data of ch2, is printed,
The scale numeral to be displayed is printed in the scale number display field 31 for the end side Y-axis, and all the processes are completed.

Since the present invention is configured as described above, of the two types of specific output data selected from the plurality of types of output data stored in the measuring instrument main body, the graph display area of the recording paper 21 is displayed. For example, bar graphs 33 and 34 capable of identifying each data content per unit time with respect to 32, for example, power data that is output data of ch1 is a bar graph 33 of a white pattern, and current data that is output data of ch2 is Each of them can be displayed side by side as a bar graph 34 of a black background pattern.

In addition, the scale data such as scale numbers necessary for one bar graph 33 or 34 is based on the correspondence with the starting end side Y axis 27, and the scale data such as scale numbers required for the other bar graph 34 or 33 is , And can be output and displayed on the recording paper 21 as a whole.

Therefore, the values of the two types of specific output data can be directly read as bar graphs 33 and 34 having different patterns, not only making data comparison easy, but also the previous data per unit time and the current data. Since output and display can be performed without performing comparison processing with data, it is possible to simplify creation of a program 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 a measuring instrument main body are displayed on a graph display area of a recording paper. Can be displayed in parallel as a bar graph that can identify each data content for each unit time, and the scale data necessary for one bar graph is based on the correspondence with the starting end side Y axis and the other bar graph The scale data necessary for the graph can be arranged respectively in correspondence with the Y axis on the terminal side, and the whole can be output and displayed on the recording paper.

Therefore, the values of the two types of specific output data can be read by bar graphs, which makes it easy to compare the data and output the data without performing the comparison processing between the previous data and the current data per unit time. Since it can be displayed, it is possible to simplify the creation of a program for data processing.
