Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a ground monitoring control panel suitable for monitoring and controlling the status of an industrial plant [Technical background of the invention and its problems] Conventional plant A monitoring control panel has a huge number of switches, switches, lamps, meters, push buttons, etc. on its large panel.
As the size of the sill plant increases, the number of operating units and instruments such as recorders is increasing, and the space for arranging them is reaching its capacity limit. Therefore, efforts have been made to consolidate and display ground information on a CRT display, downsize the operating device on the panel, and reduce the panel itself.In other words, the CRT display is used primarily as a monitoring instrument. It has been used for As a result, the monitoring side of conventional control panels can be significantly downsized.

On the other hand, as the operating device becomes smaller, there is a risk of erroneous operation, and there is a limit to miniaturization, and the space occupied by the operating device in the entire control panel is increasing. In addition, as plant automation progresses, it is possible to reduce the number of operating devices to some extent, but in the event of a plant emergency, manual operation based on visual inspection, confirmation, and judgment by plant operators will be required. Therefore, it is impossible to completely remove the operating devices from the panel, and they must be physically arranged for each ground system.

As a result, plant operators are required to carry out manual operations such as the location of the operating parts to be operated under various plant conditions, the operating procedures, the effects on other gland systems, and the operations of other gland systems. It is important to remember the complicated operations of the ground and take appropriate actions.If you make a mistake in visual inspection, confirmation, or judgment, there is a risk of misoperating the ground. With the change in
Even if they are actively introduced (for recorders, lamps, etc.), they are still large in size and place a heavy burden on operators. Furthermore, the CRT used as a monitoring instrument is small in size and requires close viewing for visual inspection, making it inconvenient for monitoring from a distance.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a compact plant monitoring and control panel that can easily monitor and control the ground and safely operate the plant.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows the configuration of a plant monitoring and control panel according to the present invention. A calculator 3 that takes in process data 2 from the plant 1 edits the results of arithmetic processing of these data and displays plant information 6 on a screen 5 installed on the vertical surface of the pincer bead 4. The screen controller 7 controlling the image is transmitted as K image control data 8.

Conventionally, the CR7 display device 9, which was placed as a monitoring instrument on the vertical plane of the pentidate 4, is a horizontal mF of the pentidate 4.
! The plant monitoring and control image data 1° incorporated in the B section and sent from the computer 3 is displayed. That CR
In the evening, the T sensor 11 is displayed on the display device, and the ground operator will check the T sensor 11 in the evening. When -11 is touched with the finger 12, the coordinate signal 13 is transmitted to the computer 3. The computer 3 processes the transmitted coordinate signal 13t, and when a plant control command is detected, issues a ground control signal 14 to the ground 1 to control the plant.

Next, the basic operation of the plant monitoring and control panel of this embodiment will be explained using FIG. is calculated and determined by the plant state judgment logic that has been programmed into the computer 3 in advance (1 ground state judgment)
52). As a result of the 'Plant status determination' 52, the computer 3 picks out the minimum necessary items to be monitored in the current ground status by performing arithmetic processing using the crisis function that has been compiled in advance.
The image control data 8 is created as ``sleef display data editing'' 53), and is transmitted to the screen controller 7 to be displayed on the screen 5 as glint information 6 (ground data display on one screen #54).

In addition, in the plant state, the necessary minimum ground monitoring and operation control items are picked up according to the processing logic programmed in advance in the computer) and created as data that can be displayed on the CR7 display device 9.W''CRT display Data editing #55) is transmitted to the CR7 display device 9 and displayed as a ground monitoring function image and a plant control image ("Display of monitoring and control images on CRT" 56).

Here, the plant operator accurately visually and confirms the plant status using the plant f'P1 information 6 displayed on the screen 5 and the plant monitoring and control information displayed on the CR7 display device 9 (''7°2 Grasping of the ground condition by the driver, ground monitoring, and confirmation of the control image 8#5
7).

Next, in order for plant operators to monitor the status of any ground system or perform control operations on any plant system, a C
When you try to touch the ground monitoring and control information displayed on the R7 display device 9 with your finger 12, you touch the touch sensor 11 provided on the surface of the CRT display device 9 (@Touch sensor coordinate signal detection” 59) .

At this time, the computer 3 detects the coordinate signal 13 transmitted from the touch sensor 11 (Touch sensor coordinate signal detection '59), and the ground monitoring and control image data 10 currently displayed on the CRT display device 9 and the coordinate signal. 13 and detects that the function selected by the ground operator is the plant monitoring or ground control function (@selected function determination #60).

If the result of "selection function determination" 60 is received by the plant monitoring function (61), 'check whether a specific screen display item is requested' (62), and if so (
63), pick up the gross data 2 of the plant 1 that matches the required ground monitoring function, process it, and edit the new image control data 8. Ground data display with plant information 6 by transmitting to 7 ``54).

In addition, we checked whether specific screen display items were requested and found in #62 that no specific screen display items were selected, and that it was necessary for plant operators to select more detailed screen display items. If there is (6
In 4), after editing the list of newly subdivided screen display items in "CRT display data editing" 55, 'CRT
Monitor and control image display” 56.

Through this process, the ground operator will again be able to
Visually check and check the screen display items displayed on the display device 9 57, and touch the item to be displayed on the screen 5 with the finger 12 (finger contact #58 on the 1 Tazuchi sensor). As a result, the coordinate signal of the touch sensor is Detected #59,'
Selection function judgment” 60 determines that the ground monitoring function is selected (
61) To be done. At this point, after reconfirming that a specific screen display item has already been selected (63), process data of fc ground 1 2'f! : Pick up, perform arithmetic processing, "edit screen display data" 53, and display ground data on one screen #54.

On the other hand, if the plant control function is selected as a result of the "selected function determination" 60 (65), it is checked whether a specific ground control item has been selected, and at the same time, the validity of the control content is programmed. Judgment based on the theory (
“Specific Control Items” 66) If the result is that no specific control items have been selected or the validity of the control content cannot be obtained (67), the plant operator will ask the plant operator again to confirm the specific control items. A list of new subdivided plant control items is displayed on the CRT to prompt the selection of functions.
In the evening, edit #55 and display the monitoring and control image to C and RT #56.

Here, the plant operator visually inspects, confirms, and judges the plant control items displayed on the CRT display device 9. By touching the image of the plant control items with his/her finger 12, the operator is able to touch the plant control item image displayed on the CRT display device 9. Finger contact #58 is made. Calculator 3 says “Result of selection function judgment #60,
Determine that the plant control function has been selected and select “
Determine whether a specific control item has been selected or not #66゜ As a result of the determination, if a specific plant control item is selected and the content is also found to be valid (68), the currently selected item is selected. The following process is performed to confirm whether the plant control items that have been set can really be applied to the plant 1.

In other words, it is determined whether the ground control item has already been selected by the ground operator in the current plant state (control reconfirmation #69), and if this is the first selection command (70), the plant control The item is stored as selected (1 selected item memory '77).Then, the image of the selected ground control item is flashed on the CRT display R9, and the selected ground control item is sent to the plant. The system displays an image of a plant control request and cancellation along with a message asking if it is ok to do so, prompting the plant operator to confirm the plant control again ("Plant control reconfirmation display"). 72) 0 In this state, when the plant operator touches the touch sensor 11 on which the plant control request image is displayed with his finger 12, ("finger contact on touch sensor 158"), the computer 3 outputs the coordinate signal of 1 touch sensor. "Detect" 59, and further "determine selected function" 601, ``66
As a result of ``Plant Control Reconfirmation'' 69, it is determined that ``Selection Item Memory 1'' 7 has been selected. On the other hand, if the plant control item has already been selected (73), the selection is made so that the plant control signal 14 is not immediately emitted when the plant control item is selected in a later plant control operation. After that, the computer 3 issues one grand control command #75 to the plant 1 according to the ground control item. to transmit.

As a result, the state of the plan)IU will change, and in order for the computer 3 to collect "ground data J'51" again, a new 1-ground state judgment #52 is performed.
The above-mentioned plant monitoring control procedure is repeated.

In addition, if it is determined that the plant operator mistakenly selected another plant control item without selecting the plant control request or cancellation image (76), the previous time stored in the computer 3 1 Delete the selected item and display the list of brand control items again with 74 'Edit CRT display data'
55 and then monitor the @CRT, display the control image #56, or send a message to the effect that there was an incorrect selection.
It is displayed on the T display device 9.

FIG. 3 shows another embodiment of the present invention, in which a plant monitor has a configuration in which a plurality of CRT display devices 9 with touch sensors 11, a plurality of screens 5, and a screen controller 7 are connected to a computer 3. The control panel shows the following ground monitoring control.

As a first example, in a normal state, a specific CRT display device 9 with a touch sensor 11 and a specific screen 5 are assigned to monitor and control a specific plant system, and when the CRT display device 9 with a touch sensor 11 or the screen 5 fails. In that case, will the plant system be monitored on the normal CRT display device 9 with touch sensor 11 or screen 5? By taking charge of control, it is possible to compensate for the function of a malfunctioning device.

As a second example, by allocating the plant monitoring function and the ground monitoring control function to specific CRT display devices equipped with touch sensors, it is possible to compensate for the failure of the device in the same manner as in the first example. The figure shows yet another embodiment of the invention. In the configuration of the figure,
Two computers 3 are provided, and during normal operation, one computer 3 monitors the operating state of the other computer 3 that monitors and controls the plant, and at the same time performs other calculation processing. If the computer 3 that monitors the plant and controls the plant causes an abnormal operation, such as destruction of the self-storage device, the other computers 3 will detect this and
Computer 3 that immediately performed plant monitoring and control processing

2, 14), CRT display device 9 (10), screen controller 7 (8) and touch sensor 11 (13)
(The dashed lines in the figure indicate each route after reconnection) and plant monitoring.

While continuing the control function, a message is displayed on the display such as the CRT display device 9 to the effect that the computer that was previously performing plant monitoring and control 111 has failed.

By doing so, the safety of plant monitoring and control can be ensured.

In the above embodiments, a CRT display device equipped with a touch sensor 11 is used as a means for plant monitoring and control by plant operators. For this purpose, it is also possible to use a combination of push buttons, switches, etc., which can perform a similar function to the touch center t-11 manual input to the calculator 3.
