(B) Prior Art Conventionally, in addition to the automatic balancing type recorder used to display and record process data, there are also devices that can display process data at multiple points on the screen of a display device such as a CRT. be. In such a device, as shown in FIG. The positions of the reading scales 81 to Si1 are fixed. Therefore, the number of displayed process data D1 to Dn is large (I see, the position of scale 3+-8n and the displayed process data 9D+ to Dn are separated from each other, making it impossible to read the process data values accurately. , scale 81 to Sn
There is a problem that the area occupied by the display is large (the area occupied by the display is large), and the originally necessary process data D+-Dn cannot be displayed for a long time.

(e) Examples Hereinafter, the present invention will be explained in detail with reference to Examples from FIG. 2 to FIG. 4.

FIG. 2 is a block diagram of the process data display device of this embodiment. In the figure, reference numeral 1 denotes a process data display device, 2a to 2n a plurality of measuring instruments for measuring physical properties such as temperature, and 4 a multiplexer for manually switching process data output from these measuring instruments 2a to 2n. ,6
is an A/D converter that digitizes the process data input via the multiplexer 4. 8 is a central processing unit (hereinafter referred to as CPU) that performs input/output signal processing; 10
Reference numeral 12 indicates a program memory in which processing programs of the CPU 8 are stored, and 12 indicates a data memory in which process data is stored. This data memory 12a is composed of a first storage section 12a and a second storage section, both of which have the same storage capacity. 14 is a scale unit memory in which a scale unit for converting the process data read from the second storage section 12b of the data memo 1J12 into an industrial quantity value is stored in advance, and 16 is a scale unit memory read from the second storage section 12b. The processed process data is multiplied by the middle scale read from the scale unit memory 14. This is a CRT display that displays various numerical values. Also, 22 is a character memory that stores data for displaying scale lines, percentage values, etc., 24 is a key manual section, and this key manual section 24 is a character memory. 22 has a scale movement key 26 for specifying the display position of the scale line stored on the screen, and a time zone setting key 28 for setting the display time zone of process data. The fixed time data succession means 30 supplies a time designation signal based on the designated time corresponding to the display position of the scale line to the second storage section 12b as a successive process data address designation signal. an up/down counter 32 that outputs a count value corresponding to the amount of movement of the scale line displayed by the manual key from 26; and a timer circuit 34 that stores the display time period of process data set with the time setting key 28. and an adder 36 that adds the count value of the up/down counter 32 to the count value corresponding to the display time period output from the timer circuit 34. and the count value corrected by the adder 36 are input together, the key manual section 24 determines whether the specified display time is within the display time zone, and this determination signal is given to the mf character data memory 22. Next, the process data display operation of the process data display device 1 having the configuration described in ``1'' will be explained. Since the process data is sequentially input to the CPU 8 via the device 6, the CPU 8 stores these process data in the first storage section 12a and the second storage section 1 of the data memo 1J12.
2b and stored here. If the display time period of the process data is set in the timer circuit 34 in advance using the time period setting key 2e of the key manual section 28, the timer circuit 34 will set each count value corresponding to the set display time period. is output to the first storage section 12a as a successive address designation signal, so all the process data within the display time zone designated by the address is read out from the first storage section 12a, and this process data is sent to the image signal conversion circuit 18. After being converted into an image signal, it is output to the display device 20. Therefore, process data D1 to Dn are displayed at multiple points on the screen Q of the display device 2, as shown in FIG. On the other hand, the adder 36 receives the count value corresponding to the display time period output from the timer circuit 34 and the up/down counter 3.
Since the count value corresponding to the amount of movement of scale line L outputted from 2 is input together and the two are added, the display position of scale line L can be changed by operating scale movement key 2G of key manual section 24. When specified, this means that the time at which the process data corresponding to the specified position of this scale line L is to be displayed is specified. Therefore, adder 36
The added count value is output as a time designation signal. This time designation signal is transmitted to the second storage section 12b and the determination circuit 3a.
and is commonly input to the image signal conversion circuit 18. The determination circuit 38 simultaneously inputs the time designation signal from the adder 36 and the count value from the timer circuit 34, and determines, based on both signals, that the position where the scale line L should be displayed is within the display time period of the process data. Determine whether or not. The determination circuit 3ε outputs a character data read signal as a determination signal to the character data memory 22 at the next stage when the scale line L is at the position to be displayed within the display time period. The data for displaying the scale line L is read out,
This data is displayed 37 via the image signal conversion circuit 18;
, 20. In the meantime, the time designation signal from the adder 36 is output to the display H 211 via the image conversion circuit 18, so the image on the display 20 is
Above +, a scale line L is displayed at a predetermined position designated by the scale movement key 26. Furthermore, when the position of the scale line L to be displayed is outside the previously set display time zone, the determination circuit 38 gives a successive percentage value signal as a determination signal to the character data memory 22 at the next stage. Data for displaying a percentage value is read out from 22, and this data is output to the display 20 via the image signal conversion circuit 18. Therefore, the display 20 shows 0 to 1 instead of the scale line L.
A percentage value of 00% is displayed at the left end of the display frame F for the process data D1 to Dn. Furthermore, since the time designation signal output from the adder 36 is given to the second storage section 12a of the data memory 12 as a read address designation signal, the time corresponding to the set position of the scale line L is sent from the second storage section 12a. The process data at is read out, and this read process data is sent to the multiplier 10 at the next stage. The CPU 8 reads the scale unit adapted to each process data from the scale unit memo 1J14 in synchronization with the input timing of the process data to the multiplier 16, and outputs it to the multiplier 16 as well.

The multiplier 16 sequentially applies the scale unit from the scale unit memory 14 to each process data from the second storage section 12b. Therefore, the multiplier 16 outputs process data converted into industrial quantity data, which is provided to the display 20 via the image signal conversion circuit 18.

As a result, data values P1 to Pn at a predetermined time at the intersection position of the scale line L and each continuously displayed process data [)+-1)n are displayed at a position close to the display frame F, for example, at -L force. .

In addition to the above-mentioned embodiment, a channel selection key is provided in the key operator section 24, and as shown in FIG. 4, by operating the channel selection key, a scale line L' corresponding to the channel is displayed and It is also possible to display numerically the data at the intersection of the corresponding process data D' with the scale line L' on the display frame F'.

According to the present invention, the scale line is displayed on the screen of the display device, this scale line can be freely moved in parallel, and the scale line is displayed continuously with the scale line. Since the value of process data at a predetermined time at the intersection position with each process data can be displayed at the same time, process data displayed at multiple points can be displayed for a long time. This enables accurate reading of process data values. In addition, since current and past data can be displayed freely, excellent practical effects such as easier monitoring and control of various processes can be obtained.
