DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for saving measurement data to an IC card for a waveform recorder, and more particularly, to a method for saving an IC card between waveform recorders having different numbers of channels at an input section. The present invention relates to a method for saving measurement data to a waveform recorder IC card that can be shared while maintaining compatibility.

[0002]

2. Description of the Related Art Many waveform recorders are provided with a plurality of channels, such as four channels and eight channels, in an input section.

In such a waveform recorder,
As shown in FIG. 7, after storing the measurement data captured via the input unit in the data RAM, the data RA
Measurement data can be extracted from M and output as a waveform via an output unit such as a display unit or a recording unit, and can also be saved as measurement data on an IC card as an external storage medium. I have.

FIGS. 8 and 9 show an example of saving measured data to an IC card using the above-mentioned waveform recorder. FIG. 8 shows a pattern when the input unit has four channels. FIG. 9 shows patterns when the input unit has eight channels.

[0005] According to these figures, measurement data taken into the apparatus main body 1 via the input unit 2 is data RA.
After being stored in the M3, it is taken out of the data RAM 3 under the control of the CPU 4, output as a waveform to an output unit such as a display unit equipped with a CRT or a recording unit equipped with a printer, and has an IC as an external storage medium. The card 5 can also be saved.

In this case, in the pattern of FIG. 8 in which the input unit 2 has four channels, the measurement data is separately stored in the data RAM 3 for each channel, and the data for four channels is stored in the IC card 5 as one data. Even if the input unit 2 is provided with eight channels as shown in FIG. 9 and the input unit 2 is provided with eight channels as shown in FIG. And save all at once.

[0007]

By the way, in the case of the above-mentioned conventional method, the measurement data from all the channels constituting the input unit 2 is stored in an IC under a single file name.
Since all the data can be saved in the card 5 and there is no need to prepare a corresponding file for each channel, there is an advantage that the operation for saving the measurement data becomes easy.

However, in this case, in the IC card 5, measurement data for four channels is input to a waveform recorder (hereinafter referred to as a four-channel recorder) having four channels of the input unit 2, In a waveform recorder having eight channels (hereinafter referred to as an eight-channel recorder), measurement data for eight channels is saved in one file.

Therefore, in the case of the above-mentioned conventional method, one IC card can be used, for example, with four different channels.
There is a disadvantage that the channel recorder and the eight-channel recorder cannot be shared while ensuring compatibility.

[0010]

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-mentioned problems in the conventional method, and has as its object to enable the same IC card to be shared between waveform recorders having different numbers of channels. The configuration features include an input unit for converting the waveform data into digital data and capturing the converted data as measurement data, a memory capable of writing and reading the captured measurement data at any time, and measurement data. A device main unit including at least a central processing unit for controlling the components of the above components based on an operation input from the operation unit, and an output unit for outputting necessary data; and a measurement unit mounted on the device main unit. It consists of an IC card arranged to save data, and the measurement data taken into the device main body is based on the number of channels at the input section of the device main body. When a plurality of n, is to save the IC card by giving the name of the file that can be collectively designated to another integer multiple of the number of channels n from being saved channel specified items that are set in advance.

[0011]

For this reason, by selecting and specifying a file name from which measurement data from each channel can be collectively specified by an integral multiple of the number of channels n from preset save channel specification items, The measurement data taken into the IC card can be collectively saved in the IC card separately for the integral multiple of the number n of channels, and therefore, the waveform recording provided with the input section having the integral number of the channels n Compatibility of the IC cards between the totals can be ensured, and effective use of the IC cards can be achieved.

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

FIG. 2 shows an example of a schematic configuration of an apparatus used in the embodiment of the present invention. The whole of the apparatus is provided with an input section 12 for converting the waveform data into digital data and capturing the converted data as measurement data. A memory (data RAM) 13 in which measured data can be written and read at any time, a display unit 18 such as a CRT for outputting necessary data including the measured data as an image, and a recording unit 17 for printing and outputting. And the necessary memory means (R
OM, RAM), and at least a central processing unit (CPU) 14 for controlling and controlling the above components based on an operation input from an operation unit 15. An IC card 19 is provided so as to be mounted and capable of saving measurement data.

FIG. 1 is a flow chart showing an outline of a processing procedure of the method of the present invention performed by applying the present invention to the apparatus shown in FIG. 2, using an 8-channel recorder as an example.

In this case, on the side of the apparatus main body 11, as shown in FIG. 3, only one of channels 1 to 8 is selected and designated, or channels 1 to 4 or 5 to 8 are selected. A save channel designation item is provided which allows the user to select and designate all channels up to a single channel.
It can be saved in the C card 19.

This will be described in more detail with reference to FIG. 1. First, a save channel designation item "ch1--" which can collectively select and designate channels 1 to 4 from among the save channel designation items in FIG. 4 "
One of the save channel designation items "ch5-8", which can be collectively selected and designated for channels 5 to 8, is designated.

At this time, the save channel designation item "ch
By selecting "1-4", the measurement data of channels 1 to 4 can be saved in the IC card 19 under one file name (for example, "FILE-1").
By selecting and specifying “ch5-8”, the measurement data of channels 5 to 8 can be saved in the IC card 19 under another file name (for example, “FILE-2”). FIG. 4 shows an example of a display pattern in a case where the measurement data is saved in the IC card 19 according to the procedure of FIG. 1 and then the save status is output and displayed on the output unit 16 of the 8-channel recorder. FI
The measurement data of channels 1 to 4 is saved under the file name of “LE-1”, and the measurement data of channels 5 to 8 is saved under the file name of “FILE-2”. You can check.

FIG. 5 shows an example of a display pattern when the same IC card 19 is output and displayed on the output section 16 of the four-channel recorder, and in this case, "FILE-2" The measurement data of channels 5 to 8 saved on the side of "" is replaced with the measurement data of channels 1 to 4, and "FILE-
1 "and" FILE-2 "
In both cases, it can be confirmed that the measurement data of channels 1 to 4 is saved.

Since the present invention is constructed as described above, it is possible to collectively designate the measurement data from each channel separately from the preset save channel designation item by an integral multiple of the number of channels n. By selecting and specifying the file name, the measurement data taken into the apparatus main body 11 can be collectively saved on the IC card separately for an integral multiple of the number n of channels.

Therefore, between waveform recorders having input units 12 having an integral number of channels equal to the number n of channels (for example, between a four-channel recorder and an eight-channel recorder as shown in FIG. 6). ), For example, "FIL
Since the same IC card 19 can be shared under the file name of "E-1" and the file name of "FILE-2", compatibility can be ensured and effective use of the IC card 19 can be achieved. it can.
