Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic self-balancing multi-pen recorder that has a built-in microprocessor and allows setting input to be entered using a keyboard.

The electronic self-balancing recorder records the level of the input analog signal continuously along the length direction of the recording paper (C time axis direction), and adjusts the recording paper feed speed and other recording conditions as necessary. It is designed so that it can be set up. However, the condition setting method in the conventional recorder requires complicated additional mechanical elements and is cumbersome to operate.

First, there are ways to set the paper transport speed in conventional recorders, such as by changing the gear arrangement of the paper feed lever transmission mechanism, or by controlling the paper pulse motor with a digital switch. It is difficult to make minute changes to the set value, and the latter method has drawbacks such as the difficulty of changing the set value without passing through the recording paper speed other than the set value while the recorder is operating. Also, the units in which the recording paper feed speed can be set are the speed unit itself, such as (cm/hr, ), Ccm/mIn, ), and (cm/5ee), and the reciprocal unit, that is, the time to move a unit distance, (sec/
There is no method that allows you to set a desired value using cm ) or the like. Furthermore, there are no programs that have a program function that automatically changes the recording paper feed speed over time.

Next, in the case of a multi-pen recorder, each pen is arranged so that it is sequentially shifted in the chart paper feeding direction, so that each pen can move freely in the chart paper width direction. Interval means a time difference that is inversely proportional to the feed rate.

Therefore, in order to avoid time errors in multi-phenomenon recording, pens other than the one at the reference position must be driven by inputs that are sequentially delayed by the time corresponding to the pen interval. For this purpose, special electrical circuits and digital switches or transfer switches are used. However, it is difficult to provide a time difference correction means that can accommodate all of the recording paper feed speeds that can be set over a wide range and can also compensate for even the slightest deviation of the pen tip when replacing the pen.

Furthermore, some self-balancing multi-pen recorders have an upper/lower limit setting and alarm mechanism that sets upper or lower limits for the human input signal and generates an alarm signal when the signal exceeds these limits. The method is a mechanical method that responds to the proximity relationship between a pen carriage driven in accordance with an input signal and an engaging means that is adjusted and fixed at the upper and lower limit level positions on the recording paper, and the setting operation is troublesome. There are also problems with accuracy.

The present invention aims to eliminate the above-mentioned disadvantages of conventional electronic self-balancing multi-pen recorders and to provide a recorder that allows universal conditions to be set by a microprocessor.

A microprocessor is inserted between the recording paper feed mechanism and the pen drive mechanism, and a keyboard for inputting settings and a permanent memory element for inputting settings are connected to this microprocessor.

Figure 3 shows a display panel for displaying various conditions during recorder operation set by the key mode in Figure 2. It is equipped with six LED dot display sections with notes such as units, time units, and intervals.

In the above configuration, condition setting using the keyboard is performed as follows.

The recording paper speed setting mode switch (141 is located on the MANU, (manual) side, and the synchronization switch (one clause is assumed to be located in either ON or OFF). First, the recording paper stops and the operation starts. Switch (If 161 is OFF, press the O, 5PEED key which doubles as number 17".

When pressed together with the shift key (2), a function meaning "setting or changing the recording paper speed" is stored in the memory element. Next, set the recording paper speed using the numeric keys and unit keys 翰~(c), and press the entry key @no, the specified speed will be registered in the microprocessor system and displayed. Displays the numerical value and unit of the instrument.

If you want to change the speed of movement of the recording paper while it is moving, turn on switches 04), (15), and (operate switch 1), and display the current speed of the recording paper. When the speed is displayed, press the first key for the value and unit you want to change, the display (12) will display the value and the unit LED will emit light, and the recording paper speed will be changed to that value.Display (If 1"4 does not display the recording paper speed, press the 17" key (C!, 5PEED) and the shift key at the same time to display the changed speed.

Nao, if a value outside the recording paper speed setting range is entered in the microprocessor system, the display θ
@Em will continue to be displayed in the first digit to the right of the number section of No.
The unit LED does not emit light, and of course the recording paper speed does not change.

Setting and changing the / mark When the recording paper is stopped (Mode: MANU, Operate: OFF
, synchronization = ON or 0FF), press the ``8'' key (T,
(also used as mark) and the shift key to register the time mark function. As a result, the value entered using the numeric keys is in seconds, and by pressing the entry key Rono, the value entered on the display (1
On the screen, the time interval (0 seconds) during which a time mark should be added to the recording paper feed is displayed. If the input number is 3 to 4 digits, the 31st digit or higher from the right is the minute unit, so enter 2.
From the digit to the third digit, carry is carried out in hexadecimal notation, and the other digits are carried up in reverse decimal notation.

Next, when transporting the recording paper, only the T6 mark (ONlo
FF) key 4 and mark 1 key or mark l key button)
If one of the marks is pressed and a marking time interval is set, marking is performed at that time interval. If the mark l key is pressed, mark 1 will be displayed with regular interval marks using all pens.
In the case of key 011, a time mark is made in a synchronized manner with one set pen.

Setting the upper or lower limit value When the recording paper stops as mentioned above, press the "4" key (upper limit key) or @5" key (lower limit key) and the shift key (to).
and at the same time, press the math key indicating the limit value (ch), and then press the entry key (2) to display the display (I).
In case of upper limit, 'r"UXX-X"S lower limit,
``L, XX, X alphanumeric display,
The LED- marked with "excellent" emits light. (However, X = integer) After the recorder is driven, when the input reaches the set value, the display ("U" meaning the upper limit of N or the lower limit ""L" is displayed.

When the synchronization setting synchronization switch θ is in the OFF position, time correction (sequential delay processing) corresponding to the pen position of the sword signal is not performed for the plurality of pen mechanisms of the recorder. Therefore, in this case, press the 11' key (also used as the C synchronization mark key) and the shift key (to), and then press the numeric key indicating the number of pens and the entry key (32), and the display 0'4 will show the number of pens. is displayed, and after the non-recording paper starts, synchronization marks are formed by each pen.

When the synchronization switch θ→ is turned ON, the time is corrected according to the set interval of multiple pens, so as long as the pen interval is maintained exactly at the set value, each pen will have a completely synchronized instantaneous value. However, if a deviation occurs when replacing the pen tip, a corresponding time lag will be included.In order to accurately check for such time lag, it is necessary to Switch 04) to MANU.

position, the operation switch 0 is set to the ON position, and the synchronization switch (1 → is set to the CHECK position), the processor draws a square wave along the time axis with all pens, and the square wave that becomes the reference - By visually checking the deviation from the wave, the corresponding deviation of the pen tip can be checked.

To correct the confirmed deviation in time, press the 12" key (also used as the synchronization adjustment key) and the shift key (to) at the same time. This will cause the display to increase sequentially from 0% to 1.2... Release these keys when the displayed number of pens (1) reaches the desired pen number.

Synchronization adjustment is then performed by pressing the numeric key indicating the value to be corrected on the pen and entry 02.

Set the program settings and change mode switch (I4) to AUTO (automatic mode).
Set the operation switch (Io to OFF'F and the synchronization switch 01 to any position. For example, set the microphone 07'
Rosetsusa has a step of 0.1%2 in the set time interval.
. . . It is assumed that a program can be executed in which the program moves to the 10 steps of Q.9, and a unique recording paper speed set in advance is applied to each step.

To set the step interval, the “9” key also doubles as the C time interval key)
and shift key (press 2 and 2 at the same time, then press the number key representing the set time and EN), then press the IJ-key (c). To set the recording paper speed for each step that is established sequentially every time, first press the number key representing the step number, then @
This is done by pressing the 7" key (also used as the paper speed key) and the shift key Q-key at the same time, then pressing the number key and unit key representing the desired speed, and finally pressing the entry key '32. Each step is recorded sequentially. After setting the paper speed and time interval, use the numeric keys to enter which step you want to start the program with. For example, 6.
” is pressed, turn on the operate switch (I) and the program will start running from step “6”. In this case, the program will move to 6%, 7.8 steps, and 9 steps. When finished, the program operation will be stopped.

In the AUTO mode, when the operation is ON1, that is, the auto program execution stage is reached without making any program settings, the recording paper speed is set to 10 cm/min by default.

The step interval is 0 minutes, and the pen position is set to up (floating).

For this reason, the steps move from 1 to 9 instantaneously and the AUTO mode operation does not occur because the steps change to 0 or % MAN.
If no function is set in U or C manual mode, when you turn on the operate switch 06i) and press the start button, the recording paper will be driven at 10 cm/min by default. As described above, the present invention enables various control functions to be performed using a microprocessor, and can be performed only by keyboard operations without requiring mechanical operations. Furthermore, since a durable memory element is used as the memory, the settings made using the keyboard will not be lost even in the event of a power outage or failure of the power supply, making it extremely useful.

Further features of the present invention include the following.

1) Since the power supplies of the input isolated amplifiers (la) to (le) are isolated from those of the control circuits of each pen drive servo mechanism and recording paper drive mechanism of the recorder main body in this system, this configuration The recorder system is highly effective against electrical noise, and high-precision recording can be expected.

2) In a normal multi-pen recorder system, the power supply system such as the pen drive section and recording paper drive mechanism, which account for most of the power consumption, can be configured in common, so the present invention is inexpensive.

3) In general, a multi-pen recorder has gaps between each pen due to its mechanism, which makes it difficult to decipher the recorded results. To solve this problem, conventionally, each channel
Pen difference (gap) G This problem was solved by adding a delay circuit using an electronic circuit, but this system can be solved very easily by using a microprocessor and storing the delay data in RAM. It is structured so that it can be realized.

4) Since the recorder of this system is mainly configured with a microprocessor, it is possible to diversify the functions of the chart paper feed by pre-programming the chart paper feed speed and direction. It's easy to do.

5) Since the analog input signal to each channel is taken into the microprocessor as a digital value, this can be used to perform mutual calculations between each channel, and the results can be recorded with the pen of any channel. Is possible. In other words, we can overcome the current situation where only a fixed relationship can be recorded, such as simply amplifying and recording an analog input phenomenon, such as the combination of a conventional input amplifier and a recording pen, and create a highly functional measurement system. It is possible to realize a recorder.
