Description

The present invention relates to an operator's console, and more particularly to an operator's console including a touch operation device as an operation instruction input device.

[Conventional technology]

As this kind of operator's console, for example, one described in "Automation" 1986, VoL31, No. 7 "Advanced system TOSDIC-AS" P58-59 "published by Nikkan Kogyo Shimbun is known.

That is, by displaying a key symbol on the CRT and touching this symbol display portion with a finger, the corresponding screen development is performed.

In addition, regarding signal operation, an instrument that combines keys for inputting operation instructions is configured in the CRT screen and operated on a dedicated instrument operation screen.

[Problems to be Solved by the Invention]

However, operating a control signal from an operator's console using a touch panel as in the past has good operability, but also increases the chances of erroneous operation, and requires an interlock mechanism as another means. Met. Also, in the distributed control system, the operator's console section for instructing the operation and the control computer operate asynchronously, and after instructing the operation, the result of the operation of the control signal is displayed on the CRT screen. Since there is a slight delay until the message is displayed, it has not been taken into consideration that it is not immediately known whether or not the operator has surely performed the operation. In addition, as described in JP-A-56-145430, a state during operation is displayed by a lamp,
It is determined whether or not a plurality of operations follow a designated procedure, and as described in JP-A-59-103102, information from the plant and information from the control panel each time a touch operation is performed. It is also conceivable to adopt a method of determining the propriety of the operation based on the information. However, even if the former method is simply adopted, even if a part of the operation procedure is incorrect, it is necessary to repeat the series of operations, and the correction of the operation procedure is troublesome. Moreover, the state of the operation is only displayed by the lamp, and when the operation is erroneous, it is necessary to cancel the operation, and it is impossible to prevent the operation itself from being erroneous. In addition, even if the latter method is simply adopted, it takes time to determine whether or not the operation procedure, etc.
The operation result cannot be grasped immediately.

The present invention has been made based on such circumstances.

Therefore, its main purpose is to provide an operator's console which has good operability and reliability in interlock.

Another object of the present invention is to provide an operator's console in which the operator can immediately recognize that an operation instruction has been given and can reliably know the operation result of the control signal.

[Means for Solving the Problems]

The main purpose is to enable the touch operation device to be operated in two steps, and normally the operation interlock is applied to the touch operation device, and once the finger is touched, the interlock is released for a certain period of time. Alternatively, the color change is notified, and only when there is a touch operation within the above-mentioned time, the operation command of the control signal is used to achieve the result.

Further, the other purpose is to use a part of the display symbol of the touch operation device for the display of the operation instruction reception, and for that part, the control signal output command by the operation instruction and the answer back signal from the control computer are used. Switch between the two factors and display. That is, the color is changed by the control signal output command immediately after the operation command, and the color is changed by the answer back signal after a certain period of time elapses or when the answer back signal is changed.

That is, the present invention is an operator's console having a touch panel that is attached to a CRT display unit for inputting operation instructions, and displays a push button switch as a display symbol on the display screen of the CRT display unit. In a device provided with a touch operation device that generates a signal output command in response to a touch operation on the switch, an interlock that blocks at least the output of the signal output command is applied until the touch operation device is operated. Specifying that the interlock is released on the CRT display section when the interlock is released by the interlock means when the interlock is released for a fixed time when the touch operation device is operated. The operation lock display means for displaying in the The operator's console is characterized in that it is provided with signal output command output means for outputting a signal output command from the touch operation device to the controlled object on condition that the touch operation device is operated again during the period It is a thing.

Further, the present invention is an operator's console having a touch panel attached to a CRT display unit for inputting operation instructions, wherein a push button switch is displayed as a display symbol on the display screen of the CRT display unit and is displayed. A touch operation device that generates a signal output command in response to a touch operation on the switch, and outputs the signal output command of the touch operation device to a control target, wherein the touch operation device is responsive to the signal output command Of the display symbols of the operation acceptance display unit for changing the color of the operation acceptance display unit to the operation acceptance display color, and the state of the answer back signal from the control target to which the signal output command is transmitted monitored by State change detection means that outputs a detection signal when there is a change, and when a certain time has elapsed since the signal output command was output to the control target A time-up signal output means for outputting a time-up signal, a display symbol of the touch operation device in response to a signal generated at an earlier timing among the detection signal from the state change detection means and the time-up signal from the time-up signal output means Among them, the operator's console is characterized by comprising an operation acceptance display section and an answerback display means for changing the color of the answerback display section to the answerback display color.

[Action]

With this configuration, first, for the main purpose, when the operation interlock is performed, the display symbol of the interlock is displayed in the display symbol of the touch operation device in the specified display mode, and when the interlock is released, the display mode is changed. Will disappear.

Therefore, the operator can definitely select the target touch operation device.

On the other hand, for other purposes, the period during which the color change display of the touch operation device is performed by the signal output command can be selected to be 2 to 4 seconds as a time in which the answerback signal can sufficiently respond from the control target.

Therefore, before the answerback signal responds to the signal output command, the answerback signal is not used as a color change display factor, so that the operator does not feel uncomfortable.

〔Example〕

FIG. 2 is a diagram showing the overall configuration of a distributed instrumentation system to which the present invention is applied. In the figure, the operator's console 1 exchanges control data with a control computer 2 via a communication connection line 4. As shown in FIG. 3, the operator's console 1 is provided with a CRT 11 and a touch panel 12, and in the figure, 5 is a touch operation device displayed on the screen of the CRT 11, and the touch operation device 5 is an answer. A back display section 51, an operation acceptance display section 52,
It is composed of an operation lock display section 53.

In such a configuration, when the touch operation device 5 is touched with a finger or the like, it is recognized as a signal output command through the touch panel 12 and outputs a predetermined signal of the control computer 2 via communication, and The result of signal output is taken into the operator's console 1 as an answerback signal and used as a factor for switching the display color of the touch operation device 5.

Next, FIG. 1 shows a mechanism for transmitting a signal output command and confirming an answerback signal centering on the touch operation device 5.

In the figure, the touch operation device 5 is displayed on the CRT 11, and at this time, the answer back display unit 51 and the operation acceptance display unit are displayed.
For 52, the answer back signal 22 of the control computer 2
Is given to the display control unit 54 of the touch operation device 5 via the communication connection device 3 and the communication connection line 4, and has a display color corresponding to the state of the answer back signal 22.
Further, to the operation lock display section 53, a switching signal is given to the display control section 54 via the determination circuit 14 and the time-delay operation timer 15, and normally, the symbol is locked while the switching signal is off. Is displayed. Here, when the touch operation device 5 is touched with a finger or the like, the touch coordinates are detected by the touch panel 12, and the coordinates are delivered from the output unit 13 to the determination circuit 14, which is the operation on the touch operation device 5. It is determined that the timer 15 is started. By closing the switch 16 for the time determined by the set value of the timer 15, a signal output command can be issued, and the operation lock display section 53 displays the operation lock release state. If the timed operation of the timer 15 is finished as it is,
Return to the initial state, but before that, touch operation device 5
When touching, since the switch 16 is closed, the operation signal is used as a signal output command through the communication connection device 3 and the communication connection line 4 to the step transition signal of the control computer 2.
It is transmitted to 21. At this time, at the same time, the signal output command is given to the timed operation timer 17, and by switching the contact of the changeover switch 19 from b to a, the operation acceptance display section 52 of the touch operation device 5 indicates that the operation has been performed. The color shown is changed to, for example, magenta. Although the display time width can be made variable by setting the timer 17, it is usually suitable to set it to about 4 seconds. On the other hand, in the control computer 2, the control operation according to the time chart 23 is performed for each synchronization, and the step transition signal 21 is turned on by this,
The step number changes from 01 to 02.
The answer back signal 22 to the touch operation device 5 is given as the control output of the time chart, and the step
By moving from 01 to 02, it will be switched from off to on. This change is transmitted to the display control unit 54 through the communication connection device 3 and the communication connection line 4, and the answer back display unit 51 of the touch operation device 5 is changed in color. When the input signal changes from OFF to ON, the variation detecting unit 18 gives a reset command to the timer 17, whereby the changeover switch 19 switches from the contact a to the contact b. As a result, the operation acceptance display section 52 of the touch operation device 5 is changed in color by the answerback signal 22 as in the answerback display section 51.

Here, FIG. 4 is a diagram showing operation timings of signals of the touch operation unit 5 and each unit of the control computer in the above operation. First, when the touch operation device 5 is touched, a signal is output from the coordinate determination circuit 14, the time-delay timer 15 is activated, and the operation lock display 53 displays unlock. When the timer 15 is in operation, the lock is released, and after the timer time has elapsed, the lock is displayed again. Now, when the touch operation device 5 is touched in the unlocked state, the timed operation timer 17 is activated and the display color of the operation acceptance display unit 52 changes from green to magenta.
During this time, the signal reaches the control computer 2 via the communication connection device 3 with some time delay, and turns on the step transition signal 21. With this signal,
The control computer 2 steps through the process, and as a result, the answer back signal 22 is turned on, and this signal reaches the operator's console 1 via the communication connection device 3 with a slight time delay, and the answer back display unit 51. Change the display color of from green to yellow. At the same time, the change in the answerback signal causes the operation acceptance display unit 52 to switch from the operation acceptance display to the answerback signal display. That is, the display color changes from magenta to yellow. After that, when the answer back signal is turned off as a result of the step progressing on the control computer side, the display color of both the answer back display section 51 and the operation acceptance display section 52 changes from yellow to green.

Next, FIG. 5 is a diagram showing changes in the display symbols of the touch operation device 5 in the above operation. In the figure,
Reference numerals 51a to 51d denote answer back display portions, 52a to 52d denote operation acceptance display portions, and 53a to 53d denote operation lock display portions.

5a is an initial state, and 5b is a state in which the operation lock symbol has disappeared after the touch operation device 5 is touched once, and a signal output command is possible. When the touch operation device 5 is touched in the state of 5b, the display color of the display portion 52c becomes magenta,
A signal output command is issued for at least 4 seconds (4 in the embodiment.
After 5 seconds), the state becomes 5d in the figure, and the display parts 51d to 53d are changed in color by the answer back signal. After that, the control computer executes the control. The answer back signal changes and returns to the initial state 5a.

As described above, according to the above-described embodiment, the touch operation device 5 is operation-locked and can be unlocked by a simple operation of one touch, and this can be confirmed by the change of the display symbol, and the signal output can be performed. Since the operation can be performed, the operator can perform the operation with a simple procedure without making a mistake.

In addition, there is a delay due to communication and a delay due to the calculation cycle of the control computer until the answer output signal is issued from the operator's console.
If only the answer back signal is used for displaying the state of the touch operation device as in the conventional case, the operator is uncomfortable because the reaction to the operation is slow.

However, with the configuration as in the above-described embodiment, the color of the operation receiving portion is changed immediately after the operation is performed without waiting for the answer back signal, so that the reaction to the operation becomes faster.

6 (a) to 6 (c) are explanatory views showing another embodiment of the touch operation device with different control signal output commands. In each figure, the one shown on the left shows the display symbol on the CRT screen, the one shown at the center shows the change of the control signal output by the touch operation, and the arrow shows the touch operation. Also, the one shown on the right shows a wiring diagram symbol of an electrical switch equivalent to the operation of the touch operation device. Figure 6 (a)
The on / off switch 54 shown by turns on the control output signal by performing the touch operation A and continues this state. Next, by performing the touch operation B again, the control output signal is changed from on to off. By performing the touch operation A, the one-shot switch 55 shown in FIG. 6 (b) turns on the control output signal for a fixed time t, and then turns off. The same applies to the subsequent touch operation B. One-point selection switch shown in FIG. 6 (c)
The touch operation devices 56a, 56b, and 56c correspond to the selection points on a one-to-one basis. Touching the controller 56a, ie operation A
By performing, the control output signal corresponding to the selected point of the operating device 56a is turned on. Next, when the operation B touching the operating device 56b is performed, the control output signal corresponding to the selected point of the operating device 56b is turned on, and the control output signals of the operating devices 56a and 56c are turned off. Also in the following operations C and D, only the control output signal corresponding to the selected point is turned on and the others are turned off.

The above-mentioned three types of touch operation devices have different control output signals, but the operation lock method, the color change by the answer back signal, and the operation acceptance display have the same configurations as those in the above-described embodiment.

〔The invention's effect〕

As is apparent from the above description, according to the present invention, the signal output command is output on the condition that the touch operation is performed twice. Therefore, the controlled object operates by one touch operation. Instead, it is possible to determine whether the touch operation is a correct operation for a certain period of time after the first touch operation. Further, when the touch operation is not executed again within a fixed time, the first touch operation becomes invalid, so that even if the first operation is an erroneous operation, the cancel operation is unnecessary and the operability can be improved. Further, according to the present invention, when the signal output command is output based on the touch operation, the color of the operation acceptance display portion of the display symbols of the touch operation device is changed to the operation acceptance display color and displayed,
When the state of the answerback signal from the controlled object changes, or when a certain time has elapsed since the signal output command was output to the controlled object, the operation acceptance display section and answerback display section of the display symbols of the touch operation device Since the color of is changed to the answer back display color, the operation result based on the touch operation can be surely grasped, and the responsiveness can be improved.
