[Principle of Invention 1]

For example, if information of four loops as a common number (Fig. 1) is simultaneously displayed, this aspect of information monitoring of all control loops is suitable. In the example of FIG. 1, each control circuit which is divided by the circuit numbers of No. 1 to No. 4 is displayed in the corresponding partitions 1-1 to 1-4 on the screen 1 so that one circuit is displayed. Temperature setpoint SP and temperature measured value PV. However, in the case of a small display device, in the display form as shown in Fig. 1, it is necessary to slightly reduce the respective numerical values and the like, and it is not appropriate to monitor the numerical value from a position away from a certain distance.

On the other hand, as an operation assumed in the small-sized display device, there is a state in which information of only one loop is enlarged and displayed (FIG. 2). It is assumed that the numerical value and the like can be displayed slightly larger by limiting the screen of the small display device to one circuit by being limited to one of the most important circuits. However, the remaining 3 loops that are not displayed are excluded from the monitored object.

The inventors have found that the problem of displaying a plurality of circuits as described above and the problem of displaying one circuit in an enlarged manner are factors that hinder the convenience for the operator. Further, it is conceivable to add a mode in which the information of the plurality of circuits is automatically displayed at regular intervals based on the display state of the information showing only one loop. Thereby, even from a distant location (difficult It is also possible to monitor a plurality of circuits in a position where a small display is displayed and a hand that performs a switching operation of the display is not configured.

For example, considering that even if the information of the four loops is rotated and displayed for 10 seconds of display time per loop, it is considered that the control state can be sufficiently recognized for the monitoring, and if it is a slow response temperature as usual The control object, even if it is monitored in a wheeled manner, has a low probability of delaying the phenomenon of overshoot.

[Invention Principle 2]

When the value is changed with respect to the previous rotation display, the change is easily recognized by changing the display form (for example, display color). For example, when the control amount PV does not change and is stable, the value is displayed in white, and when the control amount PV changes, the value is displayed in pink or yellow.

[Invention Principle 3]

In the case where the value is changed with respect to the previous rotation display, it is easy to grasp the continuous state of the change by making the display time longer. Conversely, the display time can be made shorter even when there is no change. For example, when the control amount PV does not change and is stable, it is displayed for 5 seconds, and when the control amount PV changes, it is displayed for 15 seconds.

[First Embodiment]

Hereinafter, embodiments of the present invention will be described with reference to the drawings. 3 is a block diagram showing the configuration of a display device according to the first embodiment of the present invention. This embodiment is the same as the above invention. The corresponding example of the 1st. In the present embodiment, as shown in Figs. 14 and 15, a manufacturing apparatus that controls four control circuits (four control areas as devices) by a general-purpose regulator is taken as an example. However, even in the case of three control loops having four fewer control loops and five control loops and six control loops than the four control loops, the wheeled display of the essential part of the present invention can be applied.

The display device according to the present embodiment includes a circuit information display control unit 10 that displays information on a display object related to a control circuit for displaying an object in a device for controlling an object on a display element to be described later, and the time measuring unit 11 only When the information of one loop is enlarged and displayed, the duration of the information indicating the same control loop is measured; the display information acquisition unit 12 periodically acquires information of all the control loops from the information output device (for example, the general-purpose regulator); the display change unit 13 When the duration measured by the time measuring unit 11 reaches the predetermined duration, the latest information of the control circuit to be displayed next is obtained from the display information acquisition unit 12, and is forwarded to the loop information display control unit 10, and the screen of the display element is switched. The information of the control loop is displayed only in an enlarged manner; and the display element 14 of the liquid crystal panel or the like for image display.

Fig. 4 is a flow chart for explaining the operation of the display device of the embodiment. The loop information display control unit 10 causes the display element 14 to display information to be displayed transferred from an information output device (for example, a general-purpose adjuster) (not shown) in accordance with a predetermined rule (step S100 of FIG. 4). The general-purpose regulator forwards the information to be displayed automatically selected according to a predetermined rule or the information to be displayed selected according to the operator's operation, and forwards the information to the loop information display control unit 10.

In the case of, for example, displaying four loops, the universal regulator transfers control information or operation information corresponding to each control loop in the device (for example, the heating device) that controls the object, and the circuit number of each specific control loop to the loop. Information display control unit 10. The loop information display control unit 10 causes the display element 14 to be displayed as shown in FIG. 1 in accordance with a predetermined rule. Information corresponding to each control circuit (in the example of FIG. 1 , temperature setting value SP and temperature measurement value PV) and circuit number (No. 1 to No. 4) are arranged in a matrix of 2× horizontally and 2 horizontally. image.

Further, when one circuit is displayed, the general-purpose regulator transfers control information or operation information corresponding to the control loop of the object and the circuit number specifying the control circuit to the loop information display control unit 10. The loop information display control unit 10 displays the information corresponding to the control loop in a magnified manner on one screen as shown in FIG. 2 in accordance with a predetermined rule (in the example of FIG. 2, it is a temperature set value). Image of SP and temperature measurement PV) and loop number (No. 3).

The processing of the above step S100 is the same as the processing by the conventional general regulator. Further, in the present embodiment, as described above, the description will be made based on the state in which only the information of one loop is enlarged.

The time measuring unit 11 measures the duration of displaying the information of the same control loop when only the information of one loop is enlarged ("YES" in step S101 of Fig. 4) (step S102 of Fig. 4).

The display information acquisition unit 12 acquires information of all the control loops from the information output device (for example, the general-purpose regulator) at regular intervals (step S103 in Fig. 4). The period in which the information is obtained is preferably shorter than the predetermined duration described later. Further, the display information acquisition unit 12 may acquire information of display items of the same type as the currently displayed display items as information of all control circuits. If the temperature setting value SP and the temperature measurement value PV of the control circuit of the circuit No. 3 are displayed, for example, the temperature setting value SP and the temperature measurement value PV of the control circuit of the circuit numbers No. 1 to No. 4 can be obtained. .

When the duration measured by the time measuring unit 11 reaches a predetermined predetermined duration (for example, 5 seconds) (YES in step S104 in FIG. 4), the display changing unit 13 displays the display. The information acquisition unit 12 obtains the latest information of the control loop to be displayed next and forwards it to the loop information display control unit 10, and switches the screen of the display element 14 to display only the information of the control loop (step S105 of FIG. 4).

In the display change unit 13, a rotation order indicating the display order of the control circuit (for example, the order of No. 1 → No. 2 → No. 3 → No. 4) is set in advance. The display change unit 13 acquires information of the control loop to be displayed next in accordance with the rotation order from the display information acquisition unit 12. If the information of the control loop of loop No. 1 is currently displayed, the information of the control loop to be displayed next is the information of the loop of loop No. 2. If the information of the loop of loop No. 2 is currently displayed, Then, the information of the control loop to be displayed next is the information of the control loop of loop No. 3.

The processing of steps S101 to S105 as described above is repeatedly executed until the operation of only displaying the information of one loop is completed (YES in step S106 of Fig. 4). In addition, when the switching of the screen is performed in the processing of step S105, the duration measured by the time measuring section 11 is reset to 0, and the time measurement is started again.

(A) to (D) of Fig. 5 are views showing a display example of the embodiment. The examples of (A) to (D) of FIG. 5 are information of a control circuit that only displays the circuit number No. 1 in an enlarged manner → information of a control circuit that only displays the circuit number No. 2 is enlarged → only the display circuit is enlarged. Information of the control circuit No. 3 → Information of the control circuit of the circuit No. 4 only enlarged → Information of the control circuit of the circuit No. 1 only enlarged → Only the control circuit of the circuit No. 2 is enlarged Information →. . . . An example in which such a sequence is rotated in the screen 1 is shown.

By the wheel display as described above, in the present embodiment, the operator is even at a distance It is also possible to monitor a plurality of control circuits from a position of a display device (or a manufacturing device to which the display device is mounted) (a position where it is difficult to see a small display and a hand that performs a switching operation of the display).

In this manner, in the present embodiment, the display can be performed in such a manner that the operator can easily recognize the change in the numerical value.

[Third embodiment]

Next, a third embodiment of the present invention will be described. This embodiment is an example corresponding to the above-described inventive principle 3. Fig. 9 is a block diagram showing the configuration of a display device according to the present embodiment, and the same components as those in Figs. 3 and 6 are denoted by the same reference numerals. The display device of the present embodiment includes a loop information display control unit 10, a time measuring unit 11, a display information obtaining unit 12, a display changing unit 13, a display element 14, a display information storage unit 15, and a time indicating unit 17 (instruction unit) When the duration measured by the time measuring unit 11 reaches a predetermined duration, the time instructing unit 17 (instruction unit) acquires the latest information of the control circuit to be displayed next from the display information obtaining unit 12 for each of the same types.

When the value is changed by a predetermined amount or more, the instruction display changing unit 13 extends the predetermined duration of the control circuit to be displayed next for a predetermined period of time.

Fig. 10 is a flow chart for explaining the operation of the display device of the embodiment. The operation of step S100 of the loop information display control unit 10 has been described in the first embodiment.

The operation of step S107 of the display information storage unit 15 has been described in the second embodiment.

The operation of step S102 of the time measuring unit 11 and the operation of step S103 of the display information obtaining unit 12 have been described in the first embodiment.

When the duration measured by the time measuring unit 11 reaches the predetermined duration (YES in step S104 in FIG. 10), the time instructing unit 17 acquires the latest information of the control circuit to be displayed next from the display information obtaining unit 12, for each The physical quantities of the same kind are included in the physical quantity (for example, the control amount PV) related to the control action included in the information of the obtained control loop, and the current information of the control loop stored in the display information storage unit 15 When the physical quantity is compared, when the value of the physical quantity to be displayed for at least one physical quantity and the value of the current physical quantity is changed by a predetermined amount or more (the absolute value of the change amount is a predetermined amount or more) with respect to the value of the current physical quantity (step 10) In the case of YES in S108, the display change unit 13 is caused to extend the predetermined duration of the control circuit to be displayed next for a predetermined time, and the predetermined duration used by the time indicating unit 17 itself is also displayed only for the next time. The control loop is extended for a predetermined time (step S111 of Fig. 10).
