BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals, and description thereof is not repeated.

In the following description, an example of a control device that displays information on control or monitoring of a control object is exemplified with respect to a digital control system, but the same can be applied to an alarm. Here, the digital control system acquires the control amount from the control object, and adjusts the operation amount to be given to the control object so that the obtained control amount coincides with the preset target value. On the other hand, the alarm acquires the control amount from the control object and displays the acquired control amount. The alarm also displays or notifies whether or not the obtained control amount is within a predetermined range and whether or not the upper limit value and the lower limit value have been reached. That is, the control device according to the present invention may be implemented as any device as long as it has a function of displaying information on control or monitoring of the control object.

<A. Usage Patterns and Tasks>

1 is a schematic diagram for explaining an example of a use form of a digital control system. 1, a system for controlling three control objects (control objects 1 to 3), for example, is assumed. In such a system, three digital controllers 10-1 to 10-3 are arranged and arranged for the common control panel 1. [ The digital control system 10-1 acquires the control amount 1 (for example, temperature) detected by the detection unit 1 (for example, a temperature sensor or the like) provided in the control object 1 and displays the value (PV: Process Value) And calculates a difference from a preset target value 1 (SV: SetValue), and outputs a manipulated variable 1 (MV: Manipulated Variable) according to the difference to the control object. The same processing is performed on the digital control systems 10-2 and 10-3 for the control targets 2 and 3, respectively.

For convenience of explanation, although FIG. 1 shows an example in which three digital controllers are arranged, there are cases where more digital controllers are arranged and arranged. In the case where a plurality of digital controllers are arranged as described above, it is not easy for the operator to grasp at a glance which control object (or alarm) is monitored by each digital controller. For example, when any abnormality occurs in any one of the control objects, it is necessary for the operator to change the target value or to manually change the manipulated variable. In order to specify the digital control system to which the highly urgent operation is to be performed It is desired to be able to.

Therefore, the control device according to the present embodiment is designed in consideration of the above-described problems, and aims at improving the identification performance without increasing the display space as compared with the conventional control device. More specifically, the control apparatus according to the present embodiment displays a numerical value representing information about control or monitoring of the control object, and displays, on the background or around the displayed numerical value, To place a decorative sign.

Here, the &quot; decoration display &quot; means that the decoration display exists separately from the numerical value indicating the control or monitoring information to be controlled, which is defined by a combination of color, shape and pattern, It means a representation that occupies part or all of the space. Further, in view of the contents described in this specification, the technical meaning of the &quot; decorative mark &quot; will be understood.

<B. Device Configuration>

Next, the device configuration of the digital controller 10 according to the present embodiment will be described. 2 is a schematic diagram showing a device configuration of the digital controller 10 according to the present embodiment. 2, the digital controller 10 includes an input circuit 110, an analog-to-digital converter 112 (hereinafter also referred to as "A / D converter 112"), a display unit 120 ), An operation unit 122, a communication interface 124, a control unit 100, a digital-analog conversion unit 114 (hereinafter also referred to as a "D / A conversion unit 114" Circuitry 116.

The input circuit 110 receives the detection signal from the detection section and outputs a voltage / current signal within a predetermined range. For example, when the detecting section is a thermocouple, the input circuit 110 includes a circuit for detecting the thermoelectric power generated at both ends thereof. Or when the detecting section is a resistance temperature, the input circuit 110 includes a circuit for detecting a resistance value generated in the resistance temperature body. Further, the input circuit 110 may include a filter circuit for eliminating high-frequency components.

The A / D converter 112 converts the analog signal from the input circuit 110 into a digital signal and outputs the digital signal to the controller 100. [

The operation unit 122 includes buttons, switches, and the like provided on the operation panel shown in Fig. 1, receives the operation of the user, and outputs information indicating the received user operation to the control unit 100. [ Typically, the operation unit 122 accepts the target value SV from the user.

The communication interface 124 exchanges various information with an external device (typically, a programmable logic controller (PLC)). As an example of the system configuration, a target value may be input to the digital controller 10 from a PLC disposed in the upper part. In this case, information (for example, SV) from the PLC is transmitted to the controller (100).

The display unit 120 includes a display, an indicator, and the like provided on the operation panel shown in Fig. 1, and displays numerical values indicating information about control or monitoring of the control object. The display unit 120 further arranges a decorative display as described below in addition to the numerical value. In addition, depending on the form of the decorative display, the display unit 120 is composed of a liquid crystal display panel or an organic EL (Electro Luminescence) display panel. Or a combination of a seven-segment type liquid crystal and an LED (Light Emitting Diode).

The control unit 100 includes a processor 102, a memory 104, and a program module 106. The processor 102 is a computer for realizing processing relating to display in the display unit 120, in addition to PID control processing. ). The processor 102 executes the program module 106, thereby realizing processing as described later. At this time, the read program module 106 and data (PV and SV, etc.) necessary for processing are primarily stored in the memory 104. [ As the processor 102, a general-purpose CPU (Central Processing Unit) or an MPU (Micro-Processing Unit) may be used, or a DSP (Digital Signal Processor) for digital signal processing may be used. The program module 106 is stored in a nonvolatile storage medium such as a flash memory. The program module 106 may be configured to be updateable via various recording media. Therefore, the program module 106 itself may also be included in the technical scope of the present invention. The control unit 100 may be configured using an FPGA (Field-Programmable Gate Array). When an FPGA is employed, the program module 106 may not be stored.

The D / A conversion section 114 converts the digital signal representing the manipulated variable calculated by the control section 100 into an analog signal and outputs the analog signal to the output circuit 116.

The output circuit 116 shapes the analog signal from the D / A converter 114 into a signal according to the control object and outputs the signal. For example, when 0 to 100 [%] of the manipulated variable corresponds to a voltage signal of 0 to 10 [V], the output circuit 116 adjusts the output of the signal in this voltage range. Or the output circuit 116 generates a PWM signal having a duty ratio according to the value of the manipulated variable.

Hereinafter, some examples of the decorative display according to the present embodiment will be described.

[ The second decorative indications 22-1 to 22-3 (hereinafter, also collectively referred to as &quot; second decorative indications 22 &quot;) illustrated in Figs. 4A to 4C are a plurality It is the surrounding frame of color. Apparently, the second decorative mark 22 exists as an area surrounding the outer frame of the numerical marks 12 and 14.

However, the surrounding frame, which is the second decorative display 22, may be viewed as a part of the background. In this case, the second decorative display 22 may be expressed as part of a background of a plurality of colors different from each other.

The plurality of second decorative indicia 22 visually differentiate colors (saturation, lightness, color) so as to be distinguishable from others. The second decorative signs 22-1 to 22-3 illustrated in FIGS. 4 (A) to 4 (C) are red, yellow, and blue, respectively, .

In the case of realizing the second decorative display 22, a device such as a liquid crystal display panel or an organic EL display panel may be used as the display unit 120. However, in the case of the 7-segment method for realizing the numerical displays 12 and 14 A configuration may be adopted in which, in addition to the liquid crystals, LED groups for realizing the second decorative display 22 are arranged around the LEDs. By adopting such a configuration, it is possible to realize the second decorative display 22 according to the present embodiment while suppressing costs by making the most of the conventional structure.

The second decorative display 22 distinguishes each digital control system 10 from the other digital control system 10 by making part of the background color different from each other. By dividing each digital control system 10 by using the second decorative display 22, the operator can intuitively grasp which controlled object each digital control system 10 is controlling.

<E. Third decoration display>

In the first and second decorative displays shown in Figs. 3 and 4, the areas having different colors have the same shape, but the shapes may be different from each other.

Fig. 5 is a schematic diagram showing an example of the third decorative display of the digital controller 10 according to the present embodiment. 5, the numerical display 12 of the control amount and the numerical value display 14 of the target value are arranged on the display unit 120 of the digital control system 10. [ The third decorative signs 24-1 to 24-3 (hereinafter also collectively referred to as &quot; third decorative indicia 24 &quot;) illustrated in Figs. 5A to 5C include a plurality Of the frame. That is, the third decorative indications 24-1 to 24-3 are rim areas extending to two adjacent sides of the four sides of the display unit 120. [

The third decorative display 24-1 extends along the right frame and the lower frame of the display unit 120 while the third decorative display 24-2 extends along the left frame and the upper frame of the display unit 120 And extends along the left frame and the lower frame of the display unit 120 in the third decorative display 24-3. In other words, the plurality of third decorative indicia 24 include a plurality of partially circumferential frames of different shapes.

Further, the shape change is not limited to the shape change shown in Fig. 5, and any shape change may be employed. For example, the widths of the regions extending along the rim may be different, or the lengths extending along the rim may be different.

In addition to the form of making the shapes different from each other, the colors (chroma, brightness, color) may be different from each other visually so as to be distinguishable from others. In the third decorative display 24 shown in Fig. 5, colors used for display are set to be different from each other. That is, the third decorative signs 24-1 to 24-3 illustrated in Figs. 5A to 5C are red, yellow, and blue, respectively.

In the case of realizing the third decorative display 24, a device such as a liquid crystal display panel or an organic EL display panel may be used as the display unit 120. However, in order to realize the numerical displays 12 and 14, A configuration may be adopted in which, in addition to the liquid crystals, LED groups for realizing the third decorative display 24 are disposed around the LEDs. By employing such a configuration, it is possible to realize the third decorative display 24 according to the present embodiment while suppressing the cost by making the most of the conventional structure.

Each of the digital control systems 10 is connected to the other digital control system 10 by arranging the partial peripheral frames at a plurality of different positions and / . The third decorative display 24 further distinguishes each digital control system 10 from the other digital control system 10 by making part of the background color different from each other in addition to the change of the arrangement position and / . By dividing each digital control system 10 by using the third ornamental display 24, the operator can intuitively grasp which control target each digital control system 10 is under control.

<F. Variation of first to third decorative signs (temporal change) >

In the above-described first to third decorative displays, the configuration in which the display forms of some or all of the regions in which the numerical displays 12 and 14 exist as the background is different for each digital control system 10, The shape may also be changed in terms of time. For example, the colored background illustrated in Fig. 3, or the colored peripheral frame exemplified in Fig. 4 may be blinked at regular intervals. By making the blinking period different for each digital control system 10, by making the blinking cycles different among a plurality of digital control systems 10 displaying the background of the same color or surrounding frames, And can be distinguished from the digital controller 10.

In addition, the colored perimeter frames shown in Fig. 5 may be flickered at regular intervals as in the above-described manner, or may change their shape with time. For example, at a certain time, a colored area is extended by extending along the right frame and the lower frame of the display unit 120, and at the next time, the colored area is moved to a position along the upper frame and the right frame of the display unit 120 And the other digital control system 10 causes each digital control system 10 to be controlled by the other digital control system 10 ).

<G. Fourth decorative mark>

In the above-described modified examples of the first to third decorative signs, an example in which the background or the surrounding frame is blinked temporally has been described, but a moving display may be employed as another form of changing the background in time.

Fig. 6 is a schematic diagram showing an example of the fourth decorative display of the digital controller 10 according to the present embodiment. 6, a numerical value display 12 of a control amount and a numerical value display 14 of a target value are arranged on the display unit 120 of the digital control system 10. [ The fourth decorative indications 26-1 to 26-3 (hereinafter also collectively referred to as &quot; fourth decorative indications 26 &quot;) illustrated in Figs. 6A to 6C include a plurality As shown in FIG. In other words, in the fourth decorative mark 26, the background pattern (pattern) changes in time, so that the background appears to flow.

More specifically, in the fourth decorative display 26-1, the background moves downward of the display unit 120, and in the fourth decorative display 26-2, the background moves in the right direction of the display unit 120 And in the fourth decorative mark 26-3, the background moves obliquely downward on the right side of the display unit 120. [ In other words, the plurality of fourth decorative signs 26 include a plurality of backgrounds that are temporally changed in different forms.

In the example shown in Fig. 6, an example in which the entire background moves is shown, but a configuration in which only a part of the background moves may be adopted. In addition, the color (saturation, brightness, color) of the moving background may be different from each other. That is, the digital control systems 10 may be visually distinguished from each other by one or a plurality of combinations of a moving display direction, a background display color, and a moving background display pattern.

When the fourth decorative display 26 is realized, it is preferable to use a device such as a liquid crystal display panel or an organic EL display panel as the display unit 120. [ By adopting such a device, it is possible to enhance diversity of background displayed on the screen.

The fourth decorative display 26 distinguishes each digital control system 10 from the other digital control system 10 by making a part of the background color different in time. By distinguishing each digital control system 10 using the fourth decorative display 26, the operator can intuitively grasp which controlled object each digital control system 10 is under control.

<H. Multiple control targets>

Although the above-described first to fourth decorative displays basically exemplify a single control loop, that is, a decorative display in the case of controlling a single object to be controlled, the digital control system 10 can control the plurality of objects to be controlled independently May be controlled.

Fig. 7 is a schematic diagram showing an example of a decorative display in the case where the digital control system 10 according to the present embodiment controls a plurality of objects to be controlled. 7 shows a case where the digital control system 10 controls two control objects (1ch and 2ch) as an example.

Referring to Fig. 7, the display unit 120 of the digital control system 10 displays the values of the 1-ch and 2-ch loops in a time-wise manner. That is, after the numerical value display 12-1 of the control amount 1 and the numerical value display 14-1 of the target value for the control object 1 are validated, the numerical value display 12-2 of the control amount relating to the control object 2 and the numerical value display The numerical value display (14-2) of the value is validated. The processing of this alternation is repeated. A channel indicating which control target is the numeric value displayed at each time point is also displayed (channel indications (16-1, 16-2)}.

Even in the case of displaying numerical displays or the like related to the plurality of control objects alternately, by adding any one of the decorative displays as described above, it is possible for the operator to control the digital control system 10, It is possible to grasp intuitively whether or not the user is controlling the user.

Fig. 7 shows processing for adding the first decorative indications 20-1 and 20-2 as an example. As described above, the first decoration display 20 is a region in which the numerical displays 12 and 14 are present as backgrounds, and is set so that colors (chroma, brightness, color) are visually distinguished from others . That is, during the period in which the digital control system 10 displays the numerical value indicating the information about the control or monitoring of the control object 1, the first decorative display 20-1 is arranged on the background of the displayed numerical value, During the period in which the controller 10 displays the numerical value indicating the information about the control or monitoring of the controlled object 2, the first decorated display 20-2 is arranged in the background of the displayed numerical value. The present invention is not limited to the above-described first decorative display, and arbitrary decorative display may be selectively added.

Thus, by arranging the numerical values displayed by the digital controlling system 10 together with the decorative display for identifying the numerical value of each controlled object, the operator can control the plurality of controlled objects as a single digital controlling system 10 It is possible to intuitively grasp the controlled object as the object at each timing.

<I. Setting procedure>

Each of the above-mentioned decorative displays is made valid among the plural kinds of decorative displays prepared in advance. The decorative display to be validated may be automatically selected, but in general, the user sets the decoration display in advance, thereby enabling the decorative display to be set. Hereinafter, an example of the decorative display setting procedure will be described.

Fig. 8 is a flowchart showing the procedure for setting the decoration display in the digital controller 10 according to the present embodiment. The processing procedure shown in Fig. 8 is typically executed in the setting mode, and each step is realized by the processor 102 of the control unit 100 executing the program module 106 (both see Fig. 2).

8, when the setting mode is started, the control unit 100 displays a message on the display unit 120 indicating whether or not to select the first decoration display 20, and waits for the user's operation (Step S100 ). It is then determined whether or not the user's operation is a selection operation (step S102).

If the user's operation is a selection operation (YES in step S102), the control unit 100 displays a list of colors to be displayed as the first decorative display 20 and waits for the user's operation S104). When the user selects one of the colors, the control unit 100 sets the selected color as the color of the first decorative display 20 (step S106), and ends the setting process.

If the user's operation is not a selection operation (NO in step S102), the control unit 100 displays on the display unit 120 a message indicating whether or not to select the second decoration display 22, (Step S108). It is then determined whether or not the user's operation is a selection operation (step S110).

If the user's operation is a selection operation (YES in step S110), the control unit 100 displays a list of colors to be displayed as the second decorative display 22 and waits for the user's operation S112). When the user selects any one of the colors, the control unit 100 sets the selected color as the color of the second decorative display 22 (step S114), and ends the setting process.

If the user's operation is not a selection operation (NO in step S110), the control unit 100 displays a message on the display unit 120 whether or not to select the third decoration display 24, (Step S116). Then, it is determined whether or not the user's operation is a selection operation (step S118).

If the user's operation is a selection operation (YES in step S118), the control unit 100 displays a list of colors to be displayed as the third decorative display 24 and waits for the user's operation S120). When the user selects any one of the colors, the control unit 100 sets the selected color as the color of the third decorative display 24 and selects the list of the positions (shapes) for displaying the third decorative display 24 And waits for the user's operation (step S122). When the user selects any one position (shape), the control unit 100 sets the selected position (shape) as the position (shape) of the third decorative display 24 (step S124) and ends the setting process .

If the user's operation is not a selection operation ("NO" in step S118), the control unit 100 displays on the display unit 120 a message indicating whether or not to select the fourth decorative mark 26, (Step S126). It is then determined whether or not the user's operation is a selection operation (step S128).

If the user's operation is a selection operation (YES in step S128), the control unit 100 displays a list of patterns (glyphs) of movement display to be displayed as the fourth decorative mark 26, And waits for the operation (step S130). When the user selects any pattern (pattern), the control unit 100 sets the selected pattern (pattern) as the pattern (pattern) of the fourth decorative mark 26 (step S132), and ends the setting process .

If the user's operation is not a selection operation ("NO" in step S128), the setting process is terminated.

In the processing procedure shown in Fig. 8, it is assumed that all the first to fourth decorative displays are prepared in the digital control system 10, but only some decorative displays may be prepared. In this case, only a part of the processing shown in Fig. 8 is implemented.

<J. Automatic adjustment function>

Although the digital control system 10 described above exemplifies the process in which the manually-set ornamental display is presented in advance, a function of automatically adjusting so that the displayed ornamental display is not duplicated among a plurality of the digital control systems 10 arranged close to each other It may be mounted. Hereinafter, the automatic adjustment function of the decorative display will be described.

9 is a diagram for explaining an automatic adjustment function of the digital controller 10 according to the present embodiment. As described above, there are cases where a plurality of digital control systems 10 are arranged for the common control panel 1 (see Fig. 1). In such a case, the digital control systems 10 may communicate with each other to automatically determine whether or not to set each decorative display so that there is no overlap in the preset decorative display, or that there is no overlap.

9, for example, a plurality of digital control systems 10 each have a short-range wireless communication function (corresponding to the communication interface 124 shown in FIG. 1) To communicate with each other in a bidirectional manner. As the short-range wireless communication function, for example, a wireless LAN or Bluetooth (registered trademark) can be employed.

As an example of a specific giving and receiving procedure, after a plurality of digital control systems 10 randomly determine the ornamental display, respectively, the information of the determined ornamental display is exchanged with another digital control system 10 arranged close thereto. If the decorative signs set by the two digital controllers 10 match each other, one of them selects another decorative display. This adjustment processing is repeated for any digital controller 10 until the display of the digital controller 10 does not coincide with that of the other digital controller 10 placed close to the digital controller 10, .

In the above-described processing example, the case where the digital control systems 10 communicate with each other ad hoc to adjust the overlap of the ornamental display is exemplified. However, any one of the digital control systems 10 or the plurality of digital control systems 10 (For example, a PLC) may adjust the setting of each decorative display.

<K. Setting List Output Function>

When the decorative displays are set in the plurality of digital control systems 10, it may be necessary to manage them. In such a case, a function of outputting a setting list of the decorative display as described below is effective.

10 is a diagram for explaining the setting list output function of the system including the digital controller 10 according to the present embodiment. 10, a plurality of digital control systems 10-1 to 10-3 are connected to a network 230, to which a personal computer 200 is also connected. Instead of the network 230, a wireless communication function such as a wireless LAN may be used.

The personal computer 200 collects setting information from each of the digital controlling systems 10-1 to 10-3 and generates a list of set values in each digital controlling system 10. [ The personal computer 200 may also print out a list of set values generated from the printer 210 as a print result 220. [

11 is a diagram showing an example of a print result 220 generated by the personal computer 200 shown in Fig. 11, the print result 220 is associated with the format number (or tag name) of the digital control system 10 connected to the network 230, that is, each of the digital controllers 10 arranged close to each other The type of decorative display and its color are displayed in a list.

By using the print result 220, the operator can more easily grasp the controlled object to be processed.

<L. Benefits>
