In the case of a digital signal, it is converted into a digital signal using a simultaneous capture method. This multiplexer 2 is a type of input selection switch for sequentially switching and inputting a plurality of input analog signals to the A/D converters 2 to 3.

Digital signal (data) converted by A/D converter 3
is connected to the control device 4 via an insulating means 5 for noise removal etc.
is input. The control device 4 is an I10 port) 4a, arithmetic/
A CPU 4b that performs control processing, a ROM 4c that stores a programmer, etc. for calculation and control processing, and a RAM 4d that stores data that has been subjected to calculation and control processing.
It is roughly composed of storage means), etc. Furthermore, this RAM
4d is provided with an image memory (video RAM) area for storing CR7 display data.

The control device 4 is provided on the front of the recorder as shown in FIG. 2, and receives signals from the operation key switch 6 for setting measurement condition parameters, etc., and displays the image memory area from the control table 214. CRT display control data etc.
Display control! & Output to the device. Based on the display data and control signals, the CR7 display control table 7 outputs display data (video signal) to the CRT display device 8 (display means).

Further, the control table 4 outputs data stored in the RAM 4d to the auxiliary storage bag and (auxiliary storage means) 9. This auxiliary storage device 9 includes a floppy disk control table Fa9a for storing data etc. from the control device 4 on a floppy disk, and a floppy disk drive device 2.
? It consists of 9b etc. The auxiliary storage device 9 is composed of a memory card control table 219C for storing data etc. in a memory card (IC card, magnetic card, optical card, etc.), a memory card drive bag 219d (Fig. 3), etc. Furthermore, the control device 4 may be configured with a magnetic tape control device 9e, a magnetic tape drive device 9f (FIG. 4), etc. for storing data etc. on a magnetic tape.
From RAM4d, floppy disk of auxiliary memory,
Data stored on a memory card, magnetic tape, etc. are input via a hardcopy interface 10 to a hardcopy device 2111 (FIG. fiS2) for recording on recording paper, similar to a conventional recorder. Note that this interface 10 may conform to the R5232C and R3422A standards in order to provide compatibility with other devices.

The above A/D conversion? t213, operation key switch 6, and CR7 display control display 7. Data, control signals, etc. are exchanged between the auxiliary storage device 9, the hard copy device 11, and the control table 2!4 on a bus via the I10 baud) 4a.

Next, the operation of the recorder having the above configuration will be explained.

First, the control device 4 performs initial settings. In this initial setting, measurement condition parameters are set using the operation key switch 6 in response to the measurement analog signal input from the input terminal section 1.
It is set by the signal from.

Then, a control signal is output from the CPU 4b, and the measured analog signal is sent to the multiplexer 2. It is converted into a digital signal by the A/D conversion device, and I1
0 port 4a. The captured digital signal is subjected to format calculation processing such as linearization, scaling, and dimension conversion, and the processed data is stored in a predetermined area of the RAM 4d. Then, measurement analog signals are input from all of the predetermined channels, and the above-mentioned operations are repeated until they are A/D converted and stored in a predetermined memory and area of the RAM 4d.

On the other hand, the operation key switch 6 allows data etc. in the RAM 4d to be stored on a floppy disk, memory card, etc.
When operations are performed to store data on a magnetic tape, etc., the CPU 4d sends control signals to the auxiliary memory to store them. Output to 9. The floppy disk control device 219a, memory card control device 9c, or magnetic tape control table fi9e that input this information is the floppy disk drive device 219b and the memory card drive device 9d, respectively.
.

The magnetic tape drive device 9f is put into operation. After that,
From the control table 214, data etc. in the RAM 4d are formatted according to the auxiliary storage device 9, and this processed data is sent to the auxiliary storage bag 219 via the I10 port 4a.
will be forwarded to. Then.

In the auxiliary storage device 9, the above data is stored on a floppy disk, memory card, or magnetic tape.

On the other hand, when displaying the data stored in the RAM 4d on a CRT, arbitrary time axis calculation processing and arbitrary scale @ calculation processing are performed to display the data as a trend, and these processed data are displayed on the CRT. Therefore, display coordinate processing is performed to store the data in a predetermined location in the image memory as display data. Further, data format conversion processing is performed to digitally display the above data, and display coordinate processing similar to that described above is also performed. The data subjected to these processes is stored in the image memory area of RAM4d,
The data is transferred to the CRT display control device 7 via the I10 port) 4a, and is displayed as a trend and digitally on the CR7 display device 8. After the above operation is repeated and the trend is displayed for a predetermined period of time, for example, from the current time to four hours ago, the display data stored four hours ago in the one image memory (
old data) is cleared and displayed on the CRT? t and 8, the next new display data is stored in the image memory instead, and this display data is displayed on the CR7 display device 8.

In addition, the data stored on the floppy disk, memory card, and magnetic tape in the above operation is stored in the auxiliary storage device ff.
The image is temporarily stored in a predetermined image memory area of the RAM 4d via the I10 port (19 to I10 port) 4a. As mentioned above, for example, 4 hours worth of data is stored in this RAM4d.
T display display f! Trends are displayed in 8. That is, CRT
Display display! 8, the past will be displayed again. Also,
After a predetermined period of time has been displayed on the CR7 display device 8, trend display and digital display are performed by scrolling based on data stored on a floppy disk or the like. Furthermore, the display on the CRT display device 218 can be made to reproduce any scene as appropriate by using the operation key switch 6.

The control device 4 also transfers what is displayed on the CRT display device 8 or data stored on a floppy disk, memory card, magnetic tape, etc. to a hard copy device a.
Appear to ll. Then, the hard copy device 11
7 When displayed on the display device 8, exactly the same thing is recorded on a recording paper or the like.

However, the output is exactly the same as that recorded by the conventional recorder. Therefore, the results of necessary measurements etc. can be obtained immediately and can be thoroughly studied.

Further, the auxiliary storage device 9 that stores data on the floppy disk may be made compatible with a personal computer, etc., that is, the auxiliary storage device! t
If the floppy disk stored in 9 can be input into a personal computer, various data analyzes can be performed while displaying trends and digital displays on the CRT of the personal computer, increasing its utility value. Moreover, if you use a printer etc. connected to a personal computer, a hard copy device of 2 tl.
The same thing displayed on a CRT can be recorded on paper without l.

Further, the display means is not limited to the CRT display 18 in the above embodiment, but may be another display device such as a liquid crystal display device.

[Effects of the Invention] As explained above, according to the recorder of the present invention, the input measurement analog signal is A/D converted, subjected to predetermined processing, stored, and displayed on the CRT display device. This allows the same recording to be made without the need for recording paper, and instead of recording paper, the data can be stored in an auxiliary storage device such as a floppy disk, memory card, magnetic tape (auxiliary memory), etc. It not only makes it possible to permanently store huge amounts of data, etc., but also makes it easy to manage as it stores a huge amount of data in an extremely compact way, it also allows necessary trend display and digital display based on the data stored in auxiliary memory. can be reproduced instantly.
