Abstract

PURPOSE:To attain to shorten a measuring time by arbitrarily contacting a time base on recording paper while enabling the dot display of input, by mounting an analogue/digital converter, an input data memory means, a dot data fabricating means, a time base contraction indicating means and a graphic dot printer. CONSTITUTION:A clock generator 13 imparts a clock pulse for controlling an arithmetic unit 25 to the input port 33 of the arithmetic unit 25. A time axis contraction indicating means 15 is, for example, a change-over switch and a contact piece 23 for changing over the connection with a power source side terminal 17 and an earth side terminal 19 is connected to the input port 33 through an intermediate terminal 21. When the contact piece 23 is connected to the power source side terminal 17, a wave form contracted in a time base direction is outputted but, when it is connected to the earth side terminal 19, voltage is not applied and, therefore, a usual wave form is outputted. Therefore, wave form display due to a usual time base and wave form display due to time base contraction can be selectively performed by manipulating the change-over switch 15.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a recorder, and particularly to a recorder having a time axis reduction output function.

PRIOR ART Conventionally, there has been no recorder that has a time axis reduction output function that can arbitrarily reduce the time axis and display it on the recording paper of a dot printer using human power.

Problems with the conventional technology As a result, it takes too much time to input human power such as voltage and current into the recorder and measure the waveforms displayed from the graph, printer, etc.
It was something I wanted to know. In addition, it often takes several failures to obtain the final waveform, and if the waveform is output each time, the measurement will not only take 1 dl, but will also increase the length of recording paper used. Furthermore, in actual 711Il determination, a similar problem occurs because it is often sufficient to know the approximate shape or peak value that serves as a guideline, rather than the exact shape of the waveform itself.

Purpose of the Invention The present invention has been made by focusing on the above-mentioned problems, and it is possible to arbitrarily reduce the time axis and display input in dots on the recording paper of a graphic, printer, or printer. The present invention aims to provide a recorder having a time axis reduction output function.

Summary of the invention FIG. 1 is an overall configuration diagram clearly showing the configuration of the present invention.

The recorder having the time axis reduction output function of the present invention includes an analog-to-digital converter 11 that digitizes analog input and outputs input data, and an input data storage means that sequentially stores human data in a human data memory in chronological order. 26
This corresponds to the same time axis scale of the dot data creation means 28 that sequentially reads the input data stored in chronological order to create dot 1 data and stores it in the buffer memory, and the graph ink printer 39. The apparatus is equipped with a time axis reduction instruction means 15 for setting the number of dot data to be printed, and a graphic/dot printer 39 for displaying human power from the dot data.

Embodiment FIG. 2 is a professional configuration diagram showing an embodiment of the present invention.

In the figure, 11 is an Ally RJ digital converter (
This is an A/D converter (hereinafter referred to as an A/D converter) that converts analog human input S1 such as voltage or current into a digital value of, for example, 1 word, 8 bits, and outputs it as input data to the input port 33 of the arithmetic unit 25. It is.

Reference numeral 13 denotes a black pulse generator, which supplies black pulses and pulses for controlling the computing device 25 to the human-powered boat 33 of the computing device 25.

Reference numeral 15 denotes a time axis reduction instruction means, such as a changeover switch, and a contact piece 26 for switching the connection between the power supply side terminal 17 and the earth side terminal 19 is connected to the input port roller via the intermediate terminal 21.

Connect the contact piece 23 to the power supply side terminal 17 (hereinafter ON/
+), a waveform reduced in the time axis direction is output, but when connected to the ground side terminal 19 (hereinafter referred to as OFF), no voltage is applied, so a normal waveform is output. For this reason, the switching switch.

By operating the switch 15, it is possible to select between normal time axis waveform display and time axis reduction waveform display.

In this case, if the selector switch 15 is set to ONI, only the predetermined compression ratio N will be used.

The arithmetic unit 25 includes, for example, a central processing unit (cpU) 27,
It is composed of a microcomputer consisting of a read-only memory (ROM) 29, a readable/writable memory (RAM) 31, a human capo 136, an output port 35, a pass line 67, and the like. ROM29 has 0PU
27(1) control programs are stored, including a time axis reduction processing program. R/4 M 31 is a human input data memory, a memory that stores cP calculation effects, etc., and a buffer memory that stores input data as point data with one word and one pin configuration. Contains such as. As described above, the input port 6 is connected to the A/D converter 6il, the black and white generator 1ro, the changeover switch 15, and the like. The output port 5 is connected to a graphic printer 39. The pass line 37 includes an address bus line, a data bus line, and a 1liilJ control line for connecting these.
Including stain.

The graphi dot printer 39 has 8 bits per word.
This is to record the 1 do, 0, which corresponds to the 1 word, 1 bit, and 0 data, which is reorganized by one person into 1 word and 1 bit, on the recording string 1, and by operating the changeover switch 15, for example, Dots are marked at positions corresponding to the vertical axis corresponding to the set number of dot data corresponding to the same scale (one line) on the time axis, and input waveforms, etc. are recorded.

Next, the operation of the embodiment of the present invention will be explained.

FIG. 3 and FIG. 4 are flowcharts of the time axis reduction processing program, and steps P1 to P and R are shown.

Executed by That P1~PI? In step P+, the input data is memorized in step P6.
Processing such as space reduction and printing is performed.

First, at P1 in the figure, a starting address for storing input data is set. At B2, it is determined whether the base clock for storing input data in chronological order has risen. If no, repeat reference black.

Determine the rise of the current. If YES, go to PB.

Input data at B3.

At B9, store the manual data at the manual data address O The input data address is incremented by Ps.

At B6, it is determined whether the manual data address has reached the final input data address. In the case of No, the process returns to the island and repeats steps 'Fk-B6' until reaching the final address of the input data, and stores the input data in chronological order. If YES, go to Crow.

At P, the first address where the input data is stored is read.

Clear the buffer memory on the island.

In step 1), it is determined whether the changeover switch 15 is ON.

If NO, go to Bo; if YES, go to Pl.

Pl. Now, in order to display one waveform on the normal time axis, we set the loop count) N (corresponding to the time axis reduction rate) to 1.
Set to .

In Pll, in order to display a waveform with a reduced time axis,
Set the loop count IN to 5, for example.

At B12, the contents of the manual data address are read.

The PIB creates dot data corresponding to the contents of the manual data and stores it in the buffer memory. That is, for example, a buffer memory configured with 8 bits per word and 8 bits is reconfigured into 1 word and 1 bit for use in order to store dot data. Therefore, divide the content of the manual data by 8, use the quotient to determine the address of the corresponding byte in the 8-bit/word configuration, use the remainder to determine the corresponding 1 bit, 1 position in that byte, and B, G '0''・11' from the bell
Convert to rubel and record as dot data 1. Let me @.

In this way, if a buffer memory consisting of 8 bits and 7 bits per word is used with 1 bit per word, the capacity of the buffer memory (ma) will be reduced, and the same time axis reduction rate (for 1 line) as that of graphics and desktop printers will be obtained. .

Pg and increment the manual data address by 1.

Decrement the loop count N by 1 in PIS.

At B6, it is determined whether the loop callan h N is O.

If NO (time axis reduction), return to B12 and proceed to L2~
P6. Steps 2 and 3 are repeated until finally a number of input data corresponding to the loop count 5 are read, and dot data is sequentially created and stored in the file memory. Y'E
If S, go to PI7.

In step B1, the dot data stored in the buffer memory is output to the graphics, printer, printer, printer in order from the beginning. If N is 1, one dot data is created from one manual data and stored in the file memory for 1 time, then the graph input and printer filter are used. On the same time axis scale (same line) of recording paper No. 9 (not shown), 1 do and g are marked at the vertical axis position corresponding to the contents of the data l'', , , ).

In addition, in the case of time axis reduction, the loop count N is 5, and after reading the 5 doujin card data and creating and storing the dot data corresponding to the manual data, the graphics, dot printer 9 On the same time axis scale of the recording paper, five dots and dots are marked on the vertical axis position corresponding to the content of each dot data. By reducing the time axis in this way, the length of recording paper used and the time required for recording are
Both will be one-fifth.

At B2, it is determined whether the input data address has reached the final manual data address. If No, return to the crow and repeat steps P8 to Pie until the final address of the input data is reached, marking dots in sequence on each time axis scale (each row) on the recording paper and recording waveforms, etc. .

Note that it is also possible to digitize the time axis reduction instruction means 15 by using a rotary slider or the like, and arbitrarily change the input portal value of the arithmetic unit 25 to arbitrarily set the loop count (N).

Effects of the Invention Since the present invention has the configuration as described above, the time axis can be arbitrarily reduced on the recording paper of a graphics, printer, or dot printer, and the input can be displayed in one door, so that the measurement time can be shortened. , the length of recording paper used can also be shortened. In addition, it is possible to easily know the approximate waveform and voltage peak value that serve as a guide for measurement.
