Abstract

PURPOSE:To prevent a mis-operation performed by precisely judging whether or not operation input is valid by performing display to identify an operation when the same operations are inputted in duplicate from plural terminal equipment. CONSTITUTION:When a duplication operation detecting means 7 detects the fact that the plural terminal equipment 1a-1c operate the same picture simultaneously, a display control means 12 displays the fact of a preceding operation on the display devices of the terminal equipment 1a-1c inputting an operator first, and displays that of a succeeding operation on the display devices of the terminal equipment 1a-1c inputting the operator later, and informs whether its own operation is a preceding or successing operation to the operations of the terminal equipment 1a-1c. At this time, when the operation is inputted from either opposite terminal equipment 1a-1c, the display to identify the input of the operation from the opposite terminal equipment 1a-1c is performed. Thereby, it is possible to judge whether or not the operation of its own terminal equipment is valid.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) This invention is a process controller positioned as a machine interface of a process control device, and allows mutual remote operation from multiple terminal devices (consoles). This invention relates to mutual remote operation control equipment.

(Prior Art) In general, a process controller, which is positioned as a machine interface for a process control device, allows a CRT screen to be independently operated by remote operation from a plurality of terminal devices. Therefore, in some cases, the same screen may be operated from multiple terminal devices at the same time, but in such cases, with conventional mutual remote operation control devices, commands from the terminal device that operated last always take priority. However, the terminal device of the earlier operation did not display that the later operation had entered, and the later operation was always given priority.

(Problem to be Solved by the Invention) In this way, in the conventional mutual remote operation control device, when an operation is manually performed on the same screen from multiple terminal devices at the same time, the later operation is given priority, but when the earlier operation is input, Since there is no display on the display of the terminal device, the operator who performs the advance operation may think that his operation is being utilized without knowing it, and as he continues to monitor, he realizes that his command is An abnormality occurred when you saw an operation different from the operation being executed? This is a possible problem that could lead to 11 disconnections and cause confusion in process control.

This invention was made in view of these conventional problems, and it allows each display device to display that multiple terminal devices are displaying the same screen, and also allows operations to be performed from the own terminal device first. / Mutual remote operation control device that allows the operator of each terminal device to perform the operation without error by displaying which operation is coming later and also displaying whether or not the operation from the own terminal device has priority. The purpose is to provide

[Structure of the Invention] (Means for Solving the Problems) The mutual remote operation control device of the present invention allows multiple terminal devices to operate the same screen at the same time when the same screen is operated by multiple terminal devices in an overlapping manner. Duplicate operation detection means for detecting that an operation is being performed, and when the duplicate operation detection means detects a duplicate operation from multiple terminal devices, the display device of the terminal device that first commanded the same operation is displayed on the first side. The display device of the terminal device that commanded later displays a later display indicating that it is the later-comer side, and when the terminal device of the first-comer side is operating, the terminal device of the later-comer side displays the later-comer display. A display that changes the display to one that identifies that the first mover side is in operation, and when the second mover terminal device is in operation, a display that changes the first display of the first mover terminal device to a display that identifies that the second mover side operation is in progress. It is equipped with control means.

Further, in the mutual remote operation control device of this invention,
Priority operation display control means for displaying an operation from another terminal device that performs a priority operation when the own terminal device is not on the priority side according to a predetermined priority order, such as first priority or later priority. can be provided.

Further, in the present invention, a priority order switching setting means for selectively setting the priority order of the first/last operation can be provided.

(Function) In the mutual remote operation control device of the present invention, when the duplicate operation detection means detects that a plurality of terminal devices are simultaneously operating the same screen, the display control means first detects that the operation is performed by another person. The display device of the terminal device is displayed to indicate that it is the first operation, and the terminal device for which the operation was manually performed later is displayed to be the later operation. It is possible to inform whether the operation is a first mover or a late mover. At this time, if an operation is received from the other party's terminal device, a display can be made to identify that the operation is received from the other party's terminal device.

In addition, the priority operation display control means ``displays on the display device of one terminal device that it is a first operation or a second operation, and according to the predetermined priority of the first operation or the second operation,
When an operation is initiated from a terminal device on the priority side, the operator can determine whether or not the operation from his own terminal device is valid by displaying a display on the non-priority side to identify that an operation on the priority side has entered. You will be able to perform operations more accurately and effectively.

Furthermore, the priority order setting switching means determines which of the first operation and the second operation should be prioritized (By switching the standing window, it is possible to switch and set the priority of first operation and last operation according to the characteristics of the process. .

(Example) Hereinafter, embodiments of the present invention will be explained in detail based on the drawings.

Figure 2 shows an embodiment of the present invention in which a minimum number of terminal devices are installed in the driver's cab on the first floor and the driver's cab on the second floor, and Figure 1 shows the internal configuration of each terminal device. ing.

Each terminal device 1a, 1. b, 1 c, ・
As shown in FIG.
.

3b,... and a remote control panel 4a4b for remote control
, . . . are connected to each other via a transmission line 5, and are further connected to a main computer 6 as a central processing control unit.

As shown in FIG. 1, the main computer 6 performs various types of monitoring and control over processes, and in particular includes a function implementation selection section 7 and a function implementation selection section 7 as necessary functional sections for the mutual remote operation control device according to the embodiment of the present invention. , a same tag determining section 8, another key searching section, a first/later determining section 10, an interlock function section 11, and a display control function section 12.

Next, the operation of the mutual remote operation control device having the above configuration will be explained.

Main computer 6 and each terminal device 1a, 1b.

The main operation panels 3a, 3b, and...
The main computer 6 can be operated manually by input from..., and the remote control panel 4a4b,
... makes it possible to remotely operate the corresponding process from each terminal device. During operation, CRT2a, 2b, .
It is possible to call up the necessary screens for the desired process and perform operations manually while looking at this screen information.

The detailed operation of the remote operation from each terminal device 1a, lb, lc, . . . is shown in the flowchart of FIG. Terminal devices 1a, lb.

. . , for example, from the terminal device 1a, this is inputted to the main computer 6 via the transmission line 5. Here, first, the function implementation selection section 7 selects which function to use for the duplicate operation. It is determined whether a selection has been made (step Sl).

If there is no function selected here, the first/later priority operation function is not activated, and the same screen 13a, 13 as shown in FIG.
Regardless of whether the human power to operate b is from any terminal device - 1, for example, terminal device A or lb, regardless of whether it is a first mover or a second mover, the remote operation of the process is performed indiscriminately. In FIG. 4, 14 is a program tag number, ]5 is a parameter, and 16 is an operation output.

In this step S1, the function implementation selection unit 7 selects a duplicate operation warning display function or a first/last priority setting function,
Alternatively, if the first/last priority setting switching function is selected, each terminal device 1a.

The display modes of the CRTs 2a and 2b of 1b are as shown in FIGS.
,... determine whether there is enough manpower to perform remote operation on the same screen (step S
2).

Here, if there is no human power for remote operation on the same screen, if the function implementation selection section 7 selects only the function of displaying a redundant operation warning (step S3
) The display function unit 12 displays the CRT 2a in each of FIG. 5(b) and FIG. 6(b) as an interrupt display to indicate that the current operation is manual or a first mover on the CRT2a of own terminal device]a. side display 1
As shown in FIG. 3a, "first mover" is displayed, and remote operations from the terminal device 1a are accepted (step S4).

In step S2, the CR of FIG. 5 or FIG. 6(a)
When the same tag number as that on the terminal device 1a side is selected by operating the touch panel or remote control panel 4b on the display 13b on the T2b side, the function implementation selection in step S1 is performed because the first operator who operates the same screen is involved. It is determined whether or not only alarm display is selected, and if only alarm display is selected, the process branches to the YES side (step S5).

Then, in step S6, the same tag determining unit 8 determines whether or not the first display for the same tag has been made. If there is a first display, the first/later publication cutting unit 10 determines whether the current tag selection is a later one. The display function unit 12 displays the CR of the own terminal device 1b as shown in FIG. 5(b).
An interrupt display of "later arrival" is made on the screen of T2b (step S7).

Subsequently, when an operation is input manually from the terminal device 1a of the first party (step S8), the display function unit 12 is used to inform the first party that an operation is being performed, as shown in FIG. 6(b). The "later arrival" display on the display 13b of the terminal device 1b on the side is flickered to notify the operator (step S9). In this case, the process will be operated according to the operation of the first party, as shown in FIG. 6(C).

Furthermore, when an operation is input manually from the terminal device 1b of the latecomer side (step 510), the terminal device of the firstcomer side is sent to inform the latter side that the operation has been entered, as shown in FIG. 5(C). The operator is notified by flickering the "starter" display on the display 13a (step 5).
11). In this case, the process will be operated according to the operation of the subsequent side, as shown in FIG. 5(d).

Next, if the device of this embodiment is set in the function implementation selection unit 7 to always give priority to either the first or second generation, or the function implementation selection unit 7
If the later priority setting can be switched and the setting is such that either the first operation or the later operation is given priority, in step S5, branch to the NO side and proceed to step S.
Proceed to ll.

This step S11 branches to step S12 or S13 depending on the priority function, first priority or second priority. If the first mover is given priority, if there is a selection force with the same tag from the terminal device 1b on the late mover side, the selection force from the terminal device 1b which is determined to be the late mover by the first mover/late mover judgment unit 10 is compared to the selection force from the terminal device 1b determined as the late mover as shown in FIG. As shown in b), the terminal device 1a on the starting side has “
The other terminal devices 1b, lc perform an interrupt display of "first mover".
.

In addition to informing the operator that the same tag was selected in any of the following cases, the display screen of the CRT 2b of the terminal device 1b where the latecomer manual operation was performed], 3b indicates "Latercomer".
At the same time, the ink clock function section 11 prohibits manual operation of the later operations (step 512), and only the input from the terminal device 1a on the first side is valid, and the process is overlaid.

On the other hand, if the priority is given to the latecomer, the process proceeds to step 513, where the operation of the terminal device 1a, which is the first party, is interlocked, and the text "first party" is displayed on the display screen 13H as shown in FIG. 5(C). An interrupt display of the flicker is performed to inform the operator that only the subsequent operation is valid.

In this way, the mutual remote operation lane control device of this embodiment has the function implementation selection section 7 in one device.
Depending on the implementation function selection settings, there is a function to display no display, a function to display only the first/last-comer warning display, a function to give fixed priority to either the first-comer or later-comer, and a function that allows you to switch and select the first-comer/late-comer priority setting. By switching and selecting these functions, you can either not display the first/last duplicate operation at all, or display the first/later duplicate operation and display a flicker to indicate that there is operation manpower from the other party's terminal device. Either a display is used to notify the operator, or the operation is performed with priority given to the operation input from either the first or second operator, prohibiting other operations manually, and displaying a display to identify that the priority operation is being entered from another terminal device. It is possible to do so.

However, this invention does not necessarily have to be integrated as in the above embodiments, but rather
Those that have only the function of displaying a late-comer warning display, or those that are fixed in advance to first-comer priority or second-comer priority and disable the other operation, and furthermore, it is possible to determine whether the first-comer operation or the second-comer operation is enabled. Switching settings can be made on the operator side, and each can be performed individually.

Furthermore, as a judgment for the same operation, CRT
Not only when the display screens of the tags are exactly the same, but also when a large number of tags are displayed simultaneously on one screen as shown in FIG. 7(b), a common tag number is selected. Even when an operation is performed, "first mover" or "later mover" may be displayed or a flicker may be displayed in response to the display of the same tag number.

[Effects of the Invention] As described above, according to the present invention, when the same operation is input redundantly from a plurality of terminal devices, the display of the first and second operations is displayed on the display device of each of the duplicate terminal devices. In addition, if necessary, set the side that gives priority to human operation, and display a display that identifies that the operation input is invalid for the operation input on the side that is not prioritized. Therefore, the operator can look at the display on the display device and accurately judge whether or not the operation input that he or she is trying to perform is valid, and it is possible to prevent erroneous operations.
