Abstract

PURPOSE:To preserve a partial data specified with a cursor on a monitor into a memory card or the like, by displaying a waveform data stored in a body memory corresponding to a matrix of a display screen of a waveform display means. CONSTITUTION:In displaying of a waveform data stored in a body memory 2 on a display screen 4a of a monitor 4 through a waveform input means 1, a CPU6 divides a memory area equally into (j) parts to group them by the specified number. In other words, the memory area from address 0-n-1 of the body memory 2 is equally divided into (j) parts and data at the address 0-n/j-1 are displayed in the first column of a display screen 4a and those at the address n/j-2n/j-1 done in the second column of the display screen 4a. Thus, as the position of the column (j) as time base of the display screen 4a corresponds to the address position of the body memory 2, a desired data alone in the body memory 2 can be transferred to an external memory means 3 by specifying the position with a cursor.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a data storage method for a memory recorder, and more specifically, to a memory card as an external storage means for storing part of the waveform data stored in the main body memory. The present invention relates to a data storage method that allows data to be stored in, etc.

[Conventional example]

The memory recorder is equipped with a memory of a predetermined capacity, and the input signal from the measuring section is A/D converted and then stored in the same memory (hereinafter referred to as main body memory) and sent to the printer as necessary. or displayed on the monitor.

Also, recently, floppy disks and memory cards (I
It is possible to connect external storage means such as C card), and more data can be stored.

[Problem to be solved by the invention]

By the way, when saving data in the main unit's memory to an external storage means, conventionally all the data in the main unit's memory had to be transferred to the external storage means, which meant that data other than what was needed was also saved. This is uneconomical.

This invention was made in view of the above-mentioned conventional circumstances, and its purpose is to provide a data storage method for a memory recorder that allows a portion of data specified by a cursor on a monitor to be saved in a memory card or the like. It is in.

[Means to solve the problem]

In order to achieve the above object, in this invention, A
a waveform input means including a /D converter, a main body memory for storing waveform data from the waveform input means, a waveform display means consisting of a CRT or the like for displaying the waveform data stored in the main body memory, and the memory recorder. In a memory recorder comprising an external storage means such as a memory card selectively connected to a memory recorder, and a cursor position control means for controlling the position of a cursor on the waveform display means, the voltage on the display screen of the waveform display means is The waveform data stored in the body memory is displayed on the same display screen in correspondence with the i-row and j-column, and the waveform data related to the j-column of the cursor is arranged in a matrix with i-rows in the axial direction and j-columns in the time-axis direction. The present invention is characterized in that address data in the body memory corresponding to the indicated position image is obtained, and waveform data within a desired range from the indicated address is stored in the external storage means.

[For production]

According to the above method, if the number of data stored in the main body memory is N, the memory area is divided into N/j and displayed on the screen in the i row and the j column.

Therefore, since the position of column j, which is the time axis of the display screen, corresponds to the address position of the main body memory, by specifying that position with the cursor, only the desired data in the main body memory can be transferred to the external storage means. It becomes possible to transfer.

〔Example〕

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

FIG. 1 shows a schematic block diagram of this memory recorder. According to this, the memory recorder is equipped with waveform input means 1 including an A/D converter that converts an analog input signal from a measuring section (not shown) into a digital signal. A main body memory 2 is connected to this waveform input means 1 . In this case, the main body memory 2 is assumed to have a memory area from address 0 to address n-1, as illustrated in FIG.

For example, a memory card 3 as an external storage means is connected to this memory recorder via a socket (not shown). The memory recorder also has a waveform display means (monitor).
4, and a memory area specifying means 5 for moving a cursor on the monitor 4 to specify a memory area of the main body memory 2 to be stored in the memory card 3. The designation signal from the memory area designation means 5 is input to the control means (CPU) 6, and the CPU 6 transfers the designated waveform data from the main body memory 2 to the memory cart 3 based on this signal.

Although the monitor 4 may be a CRT display or a liquid crystal display, according to the present invention, the display screen 4 of the monitor 4
As shown in FIG. 3, a is in a matrix state of i rows and j columns, with the voltage axis (Y axis) being the i row and the time axis (X axis) being the j column. Further, referring to FIG. 4, the memory area specifying means 5 is configured to
a cursor designation switch 5a for designating either cursor A or B displayed at a; a first cursor movement switch 5b for moving the cursor to the right;
A second cursor movement switch 5C that moves the cursor to the left, and a designation end switch 5d that instructs to end the designation.
Each of these switch signals is output to the CPU 6 via the I10 port 7.

When displaying the waveform data stored in the main body memory 2 via the waveform input means 1 on the display screen 4a of the monitor 4, the CPU 6 divides the memory area into five equal parts and divides the data into a predetermined number of groups. That is, as shown in FIG. 5 (for convenience of explanation, the display screen 4a is rotated 90 degrees to the right), the memory area address O to address n-1 of the main body memory 2 is 5. In this example, 0 to n
/ The data at address j-1 is displayed on the first column of the display screen 4a, and the data at addresses n/j to 2n/j1 are displayed on the display screen 4a.
will be displayed in the second column of In this way, each group's data is displayed in its corresponding column, and the final fifth
In the column, data at address (j 1)n/j"n=1 is displayed.

According to this invention, part of the data in the main body memory 2 is stored in the memory card 3 in the following manner, which will be explained with reference to the flowchart in FIG.

First, in step STI, all the data in the main body memory 2 are grouped as described above, and then the display screen 4a
will be displayed. Next, cursor A.

Variables -x and y indicating the indicated column position of B are initialized (step 5T2), and cursors A and B are displayed at the positions of the X column and y column (step 5T3). And step ST
Is the designation completed at 4? , that is, the designated end switch 5d
is at H level, and if the specification is not completed, step S
At T5, cursors A and B are activated by switches 5a to 5c.
, the presence or absence of a movement instruction is determined, the values of the variables x and y are changed according to the direction and amount of movement (steps 5T6a and 6b), and the process returns to step ST3. When it is determined in step ST4 that the specification is completed, the process moves to step ST7, and the data address 1. Calculate m.

In this case, data address l is (x-1)n/j and m is y(n-1)/j. Then, in the next step ST8, the CPU 6 selects the data address 1 to m.
In other words, the waveform data specified by cursors A and B is transferred to the memory card 3.

Although the above embodiment uses two cursors A and B, it is also possible to use one cursor and specify the number of columns in the range to be transferred starting from that cursor using a digital switch (not shown), for example. Furthermore, a floppy disk may be used as the external storage means instead of a memory card.

〔Effect of the invention〕

As explained above, according to the present invention, while viewing the waveform displayed on the monitor, it is possible to save only the waveform of a necessary part to an external storage means such as a memory card, which is therefore economical. Efficient data storage is possible.
