Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an automated power generation device using a computer equipped with a CRT display device, and more particularly to an automatic driving congestion monitoring device.

(Prior art) Thermal power plants are composed of boilers, turbines, generators, and their auxiliary equipment, but in order to start, stop, and operate these equipment in the optimal condition, it is necessary to consider the characteristics and characteristics of each equipment. Since operations must be performed in accordance with a predetermined startup order, the operations become complicated and complicated for operators, so a method has been adopted in which computers start, stop, and operate plant equipment in place of operators. ing.

When automatically operating a plant using a computer, we divide the operation into three steps and proceed with the operation while checking each step.

The three steps are defined as follows.

(g) A step of comprehensively determining the status of the equipment that makes up the plant and the temperature, pressure, etc. of various parts of the plant to determine whether the plant is in a state where a certain equipment should be operated. This is called an operation timing check.

■ A step of determining whether or not the device determined to be operated can be operated. This is called a pre-operation condition check.

(3) A step of outputting an operation command to the device and checking whether the desired operation has been completed in a state where the above items (1) and (2) are satisfied. This is called a completion condition check.

As described above, in the plant automatic operation method using a computer, when performing an operation, the operation conditions are composed of three conditions: operation timing, pre-operation conditions, and operation completion conditions.

When the pre-operation condition is not satisfied, the pre-operation condition failure item is displayed, and when the operation completion condition is not satisfied, the operation completion condition item is displayed on the display device to inform the operator of the cause of automation progress congestion.

The operator determines the cause of the plant's congestion based on the displayed failure cause, and takes appropriate measures such as manual operation if necessary. A conventional example of automatic plant operation using such a computer is shown in FIG.

A process signal a indicating the status of various parts of the plant is inputted from the plant, processed by input processing means 2 in the computer, and then inputted to operation logic table processing means 3.

The operation logic table processing means 3 performs the above-mentioned three operations for each driving operation based on the input process signal a.
It is determined whether or not the operation timing is satisfied for each device constituting the plant, whether the pre-operation condition is satisfied, and whether the operation completion condition is satisfied.

If the progress of the plant is congested, the display device 5
Messages are displayed as necessary to notify plant operators of the content.

Further, when both the operation timing and the pre-operation condition are satisfied and the operation completion condition is not satisfied, an operation command is outputted to the corresponding plant equipment via the output processing means 6.

Operation logic table 4 shows that when performing a certain driving operation,
The operation logic for each of the above-mentioned operation timing, operation pre-condition, and operation completion condition, which process signal a must reach a specified value, is stored.

Further, the confirmation processing means 7 operates when there is a command from the interactive operation panel 8. The dialog operation panel 8 displays the operation logic table 4 when a traffic jam occurs while the plant is in progress.
This is used by the operator when selecting and specifying. According to this specification, the confirmation processing means 7 takes out the specified operation logic table 4, and one input processing means 2 outputs all the process signals required for the conditions listed in the selected operation logic table 4. Enter a.

Then, the content described in the operation logic table 4 is compared with the plant status signal obtained from the input processing means 2, and the result is outputted to the display device 5. FIG. 2 shows an example of output data of the display device.

Figure 2 shows an example of displaying the contents of an operation logic table that stores the operating conditions of devices, including the name of the device to be operated, operation timing conditions (TANS), pre-operation conditions (PANS),
AND each operation completion condition (CANS).

Expressed using OR logic, the process signal is compared with the specified value of multiple plant conditions that make up each condition, it is determined whether or not they match, and the causes of the progressing traffic congestion can be understood by displaying the conditions in different colors. It is said that

(Problem to be Solved by the Invention) In order to display a table like the one shown in FIG. 2 on the display device 5 when a plant traffic jam occurs, an operator must select Plan 1 each time a plant traffic jam occurs. It is necessary to issue commands to the confirmation processing means 7 using the dialog operation panel 8, and if the table constituting the conditions is composed of multiple tables, the same operation will be required many times, making it difficult for plant operators to This results in extra effort and extra time.

The present invention is capable of displaying an operation logic table for the traffic jam without operator's operation when a defective item occurs in the conditions of the operation block table during automatic plant operation and the progress of the plant becomes congested. The purpose of this system is to automatically update the conditions made up of tables, and to centrally monitor messages and operation logic using a single CRT, thereby enabling smooth and safe automatic operation of the plant.

[Structure of the invention]

(Means for Solving the Problems) The present invention will be explained below based on the drawings. In FIG. 1, the input processing means 2 inputs a process signal a from the plant. The operation logic table processing means 3 processes the operation logic table 4 based on the process signal a processed by the input processing means 2, that is, determines the three conditions mentioned above. The operation logic table 4 stores the operating conditions of each device in the plant for each device. The display device 5 displays a faulty message and a faulty operation logic table during traffic congestion.

The output processing means 6 sends operation commands to each device of the plant. The confirmation processing means 7 creates an operation logic diagram as shown in FIG. 2 from the operation logic table 4 during traffic congestion or when a dialogue is requested. The dialog operation panel 8 is used when the driver requests the operation logic table 4 when the vehicle is not in a traffic jam. The automatic display item updating means 9 outputs the operation logic diagram created by the confirmation processing means 7 to the display device 5.

(for production) Next, the operation of the present invention will be explained with reference to FIG.

The process signal a from the plant 1 is processed by the input processing means 2 and then input to the operation logic table processing means 3.

The operation logic table processing means 3 finds an operation logic table 4 to process changes in the plant from the input process signal a, and determines whether or not the operation conditions are satisfied. If the condition is not satisfied and an operation logic table 4 is found that is causing a traffic jam in the progress of the plant, a traffic congestion operation logic table signal C is sent to the confirmation processing means 7 and the automatic display item updating means 9. When the condition is satisfied, an operation command is outputted to the corresponding device via the output processing means 6.

The automatic display item updating means 9 performs automatic display on the display device 5 in response to a signal from the confirmation processing means 7. The dialog operation panel 8 outputs to the confirmation processing means 7 a request to display an operation logic table based on an operator's instruction.

(Example) An embodiment of the present invention will be described below.

In FIG. 1, input processing means 2 processes process signals indicating the status of various parts of the plant, and operation logic table processing determines whether or not the operation timing for each device constituting the plant is established based on the process signal a. Means 3, an operation logic table 4 in which operation logic is described when performing a certain operation operation, a display device 5 that displays trouble messages and operation logic tables during traffic jams, and outputs operation signals to each device of the plant. a confirmation processing means 7 that creates an operation logic diagram as shown in FIG. 2 from the requested operation logic table, and an interactive operation panel 8 that is used when an operator requests the display of the operation logic table at will. and,
The automatic display item updating means 9 determines the automatic display timing of the operation logic table and automatically displays the operation logic table.

A plurality of process signals a from the plant are input to the input processing means 2.
is processed and input to the operation logic table processing means 3. In the operation logic table processing means 3, when the process input used in the operation logic table 4 changes, it compares and determines whether it matches the contents of the operation logic table each time there is a change.

If there is an operation logic table that satisfies the operation timing conditions, the following process is performed.

If the pre-operation condition is satisfied, an operation command is outputted to the corresponding device via the output means 6.

If the pre-operation condition or the operation completion condition is not satisfied and an operation logic table 4 is found that is causing a traffic jam in the progress of the plant, a pre-condition or completion condition failure message is output to the automatic display item updating means 9, and the confirmation processing means The traffic jam operation logic table signal C is output to 7. The confirmation processing means 7 creates an operation logic diagram from the operation logic table based on the traffic congestion logic table signal 0, and notifies the automatic display item updating means 9.

The automatic display updating means 9 determines whether or not it is automatic display timing based on the fault message signal d from the operation logic table processing means 3 in response to the signal from the confirmation processing means 7, and updates the operation logic diagram to the CRT which is performing the traffic jam message. Display. FIG. 3 shows an example of output data of the display device.

The information necessary for automatic plant operation includes multiple pieces of information such as warning messages, graphic screens with easy-to-understand system diagrams for each plant system or device, automatic operation messages, automatic operation congestion messages, and operation logic diagram displays. Conventionally, multiple (3 to 4) CRTs were used for this purpose.

The operation logic diagram is displayed from the automatic display item updating means 9 to the display device 5 using one CRT as shown in FIG.
Divide into three parts and store the information necessary for the above automated driving on one C.
It shall be possible to monitor them together using RT (however, alarm messages are important, so they are not shared).

A graphic screen corresponding to the plant conditions is requested from the operation logic table processing means 3 to the graphic screen display area 1 in FIG. The confirmation processing means 7 requests the logic chart display area 2 for an operation logic diagram corresponding to the automatic operation traffic jam message (previous, completion condition failure). A precondition failure message, a completion failure message, and an automatic operation message are requested from the operation logic table processing means 3 to the automation message area 3.

The automatic display item updating means 9 receives these display request signals and displays related information in the respective corresponding areas.

In particular, when multiple traffic jam messages are output, the automatic display item updating means 9 gives priority to the screen to be displayed, and the operation logic diagram corresponding to the automatic operation traffic jam message is displayed preferentially in the graphic screen display area 1. let

If the displayed logic diagram is composed of multiple tables, the automatic display item update means 9 has a storage device with a capacity that can store multiple pack page information, and the operation logic diagram is stored therein. After a certain period of time has elapsed, the back page information is cyclically retrieved as display information, the display contents are replaced, and the related operation logic diagram is displayed.

Divided display on a CRT is performed using a display device that allows you to freely set the display area by specifying the vertical and horizontal axes of the figure to be displayed within a predetermined area for each piece of display information. The designation of display information for these figures is also set by the automatic display item updating means 9.

As a result of the above, the conventional operator would display the operation logic diagram on other CRTs using the interactive operation panel based on the traffic congestion message every time a plant traffic jam occurs, and automatically find the cause of the traffic congestion. You can find the operation logic table inside and display it on the display device to notify the driver of the cause of the traffic jam.

Furthermore, since the display is divided and displayed on one CRT, processing can be performed without affecting the monitoring items of other CRTs.

As explained above, when plant progress is congested, the operation logic table during the congestion is displayed without the operator's operation, reducing the operator's operations and sequentially checking the relationship between the plant process status and the operation logic table. By notifying the operator, smooth and safe computer-assisted automatic operation is possible.

〔Effect of the invention〕

ω When a traffic jam occurs, it becomes possible to know the cause of the traffic jam without the operator's intervention.

■ Since some interactive operations are no longer required, drivers can quickly respond to traffic congestion factors.

(3) Information related to automation can be centrally monitored with one CRT, and other CRTs can be used effectively.
