Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for displaying output data by a serial dot printer on recording paper, and more specifically, to a method for displaying output data on recording paper by a serial dot printer attached to a measuring instrument such as a clamp wattmeter. This method simplifies the graph data processing when displaying output data, which is the result of processing measurement data, as a linear graph on recording paper as dots in the X-axis direction, and also makes it easy to know the starting point of the 8 data. This invention relates to a method for displaying output data on paper using a serial dot printer.

[Prior Art] Some measuring instruments such as clamp wattmeters are equipped with a serial dot printer, and output data obtained based on captured measurement data can be printed on recording paper as a linear graph and displayed as an output. There are things that can be done.

FIG. 6 shows a typical display example when output data regarding power is printed as a linear graph on recording paper.

According to the figure, the recording paper 1 is transported along the X-axis 2, which is the feeding direction.
The direction is the time axis, and the X-axis 2 has a scale number 4 for time (h) nearby and has a scale 3, and a scale 6 is located on the starting end side of the X-axis 2. It has a graph display area 8 divided by the Y axis 5.

Among these, near the upper side of the Y-axis 5, there is a scale number 7 for output data, for example, output data consisting of electric power value < kW.
is located.

In the graph display area 8 partitioned on the recording paper 1 in this way, the power value (kW) which is the output data is output and displayed as a linear graph 9 along the X axis 2 which is the time axis. ing.

FIG. 7 is an enlarged view of the broken line portion in FIG. 6.

According to this, data printing on the recording paper l is performed on the X axis 2.
If we use a serial dot printer in which the total number of vertical dots a for one line is 8 dots, all lines will be repeatedly printed line by line by this printer in the two directions of the X axis until the set time ends, All required output data is output and displayed as a linear graph 9.

[Problems to be Solved by the Invention] Incidentally, in the output display example shown in FIG. 6, as clearly shown in FIG. 7, the zero point position of the X-axis 2 and the zero point position of the Y-axis 5 are common. As a result, the dot located at the start point of the output data and the dots forming the Y-axis 5 will be mixed.

Furthermore, the starting end of the output data is not printed when all eight dots are used in the column, for example, a/
As a result of using two 4-dots, special graph data processing is required for the output data portion located in the first row, which inconveniently increases the complexity of program creation.

Furthermore, the position of the -th dot, which is the starting point of the output data, is mixed in the dot row on the Y-axis 5, so that at least three dots on the Y-axis 5 are located in relation to the second black dot of the output data. There is a problem in that it is necessary to guess and determine the -th dot from among the dots, and it becomes difficult to identify it.

[Means for Solving the Problems] This invention was made in view of the above-mentioned problems regarding the display method initially attempted, and its structural features are that Y-axis scale data, X-axis scale data, and measurement data a memory capable of storing output data obtained based on the graph data; a graph data conversion processing means capable of converting the output data into graph data; and a graph data conversion processing means capable of converting the output data into graph data; a memory that can store the graph data and the Y-axis scale data as print data, a print data transfer processing means that can transfer the graph data and the Y-axis scale data to the printer as print data, and a print data transfer processing means that can print the transferred print data via a drive circuit. A serial dot printer is a printer section in the main body of the measuring instrument, which is equipped with a small number of dots, and the total number of dots printed for one line by the printer in the X-axis direction as the time axis in which the recording paper is sent out is a. In the line where the Y-axis is printed, the scale number "0" indicating the zero point position of the X-axis and a
In the line following this Y-axis printing line, the scale number on the X-axis is printed at the top dot position of the a number of dots. “
The X-axis has a scale corresponding to "O", and the output data for the -line with the print start position aligned with this scale position is printed, and from then on, a graph based on the X-axis memory data and output data is printed. The purpose is to repeatedly print data one line at a time until the set time ends.

[Function] For this reason, when printing certain selected output data on recording paper among multiple types of output data that can be outputted in the measuring instrument body, the recording paper is not fed out. The total number of dots printed for one line by the serial dot printer in the X-axis direction as the time axis is a,
-The lines will be printed sequentially with line breaks.

Moreover, in the line where the Y-axis is printed, printing of the ratio data has not yet started, and in addition to the Y-axis, the starting point of the Then, in the line following the line where the Y-axis is printed in this way, the scale number of the X-axis is placed at the top dot position of the a number of dots. An X-axis with a scale corresponding to "O" and one line of output data whose printing start position coincides with this scale position are printed for the first time, and from then on, graph data based on the X-axis scale data and output data is printed. will be repeatedly printed one line at a time and output and displayed until the set time ends.

Therefore, the zero point position of the Y axis and the zero point position of the X axis can be set separately on the recording paper without having a common positional relationship. It can be printed to match the zero point position.

Therefore, the output data can always be printed at an integer multiple of a, which not only simplifies the processing of graph data but also allows the start position of the output data to be easily specified.

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

FIG. 4 shows a schematic configuration of the printer unit 11 attached to the main body of a measuring instrument such as a clamp wattmeter used for carrying out the present invention, and FIG. 5 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 voltage and current that is taken into the measuring instrument body through the input terminal undergoes necessary data processing such as performing the necessary calculations to obtain the power value as output data. /D converter to convert into multiple types of output data and store it, and specific output data selected from these multiple types of output data is stored as the fourth output data.
It is introduced into the printer section 11 shown in the figure.

The printer unit 11 into which the output data specified in this way, for example, power data (kW) is introduced, has a Y-axis scale data storage memory 12a and an X-axis scale data storage memory 12.
A RAM 12 comprising a memory 12b and an output data memory 12c;
In addition to the timer 13c, the CPU 13 includes a unique ROM and RAM, and further includes at least a RAM 14 as a graph data memory, a drive circuit 15, and a serial dot printer 16 for printing on recording paper 21. has been done.

Of these, the Y-axis scale data storage memory 12a in the RAM 12 stores Y-axis scale data consisting of not only the Y-axis 25 and the scale 26 but also a scale number 27 determined by the relationship with the input output data. , the X-axis scale data storage memory 12b contains the X-axis 22, the scale 23, and the scale number 2.
X-axis scale data such as 4 is stored in the output data memory 12c, and specific output data is stored in the output data memory 12c.

The CPU 13 also includes a graph data conversion processing means 13b for converting specific output data stored in the output data memory 12c in the RAM 12 into graph data, and a RAM as a graph data memory.
In addition to the graph data after converting the X-axis scale data and output data stored in 14, the print data is used to transfer the Y-axis scale data stored in the Y-axis scale data storage memory 12a as print data. It also functions as the transfer processing means 13a.

Further, the serial dot printer 16 prints the print data transferred via the print data transfer processing means 13a via the drive circuit 15 as a dot string in which the total number of dots in one line in the X-axis direction is a, for example, 8. can do.

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 specific output data is selected from among the output data that can be output.

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

That is, the serial dot printer 1 of the printer section 11
For the recording paper 21 provided in 6, first,
The Y-axis scale data corresponding to the specified output data is fetched from the Y-axis scale data storage memory 12a in the RAM 12, transferred to the serial dot printer 16 via the print data transfer processing means 13a, and transferred to the recording paper 21. Print as one line.

After that, as a process to print the next line, first
The character "0" which is the scale number of the axis 22 and the X-axis 22 corresponding to the - line are stored as graph data in the X-axis scale data storage memory 12b, and furthermore, from the Y-axis 25 and its scale 26, The Y-axis scale data is stored in the Y-axis scale data storage memory 12a.

Next, the character number "O" which is the X-axis scale data, the X-axis 22 corresponding to - lines (for example, 8 dots), and the Y-axis 25 and its scale 26 which are the Y-axis scale data are imported from the RAM 12. , print these as the next line.

X corresponding to the above “0” which is the X-axis scale data and the - line
Axis 22, Y-axis 25 which is Y-axis scale data, and its scale 2
6 is printed, first, the X-axis scale data 22 and 2 are printed from the X-axis scale data storage memory 12b
3.Furthermore, if the scale number 24 is also included in the print line, the scale number 24 is taken in, and these are stored in the graph data memory RA as the X-axis scale data of the print line.
Store in M14.

Next, the output data already stored in the output data memory 12c is taken in, and the graph data conversion processing means 1
3b to graph data and store it in the RAM 14, which is a graph data memory, and then output data for - rows. For example, if the number of dots for - rows is 8, then , the same process is repeated until the storage of eight pieces of graph data is completed.

In this way, after the graph data consisting of a number of dots is stored, the RAM 1 as the graph data memory
These graph data are taken in from the serial dot printer 16 via the print data transfer processing means 13a.
This is transferred to the recording paper 21 and printed as one line of output data.

Such graph processing is repeated until a preset time period ends, and it is possible to obtain a linear graph 29 for specific output data such as the output data of electric power (kWl) as shown in FIG. Note that the stone bone 28 in FIG.

Since this invention is configured as described above,
When printing a selected specific ratio data on the recording paper 21 among the plurality of types of output data that can be outputted in the main body of the measuring instrument, the time axis on which the recording paper 21 is sent out is The total number of dots printed for one line by the serial dot printer 16 in the direction of the X-axis 22 is a, and the dots are printed one by one while being line-feeded one by one.

Moreover, in the row where the Y-axis 25 is printed, printing of output data has not yet started, and in addition to the Y-axis 25, the X-axis consisting of the scale number "0" indicating the zero point position of the X-axis 22 and a row of dots or less The starting end of the shaft 22 will be printed.

In the line next to the line in which the Y-axis 25 is printed in this way, a scale corresponding to the scale number "0" on the X-axis is provided at the top dot position of the a number of dots. The X-axis 22 and one line of output data whose printing start position coincides with this scale position are printed for the first time, and from then on,
The graph data based on the axis scale data and the output data is repeatedly printed line by line until the time set in advance by the timer 13c ends and is output and displayed.

Therefore, the zero point position of the Y-axis 25 and the zero point position of the X-axis 22 do not have a common positional relationship (they can be set separately on the recording paper 21, and moreover, It is possible to print by aligning the dot position with the zero point position of the X-axis 22.

Therefore, the output data can always be printed at an integer multiple of a, which not only simplifies the processing of graph data, but also allows the start position of the output data to be easily specified.

[Effects of the Invention] As described above, according to the present invention, when printing certain output data on recording paper, the total number of vertical dots for a row is a, and the dots are inserted by -line by line feed. They will be printed sequentially.

Moreover, in the line where the Y-axis is printed, only the Y-axis excluding output data and the starting end of the In the line next to the printing line on the axis, the X-axis has a scale corresponding to the scale number "0" on the X-axis at the top dot position of the a number of dots, and printing starts at this scale position. One line of output data with the same position will be printed for the first time.

Therefore, the zero point position of the Y axis and the zero point position of the X axis can be set separately on the recording paper without having a common positional relationship. Since the output data can be printed to match the zero point position of a, the output data can always be printed at an integral multiple of a, which not only simplifies the processing of graph data but also The starting position can also be easily specified.
