BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant monitoring apparatus, and in particular, when an internal calculation value input becomes a defective input, it is possible to display a primary input which is the basis of calculation of this internal calculation value input. Monitoring equipment.

[0002]

2. Description of the Related Art Generally, in plant monitoring, the process amount (primary input value) of the plant is input to a control computer, and of these process amounts, for example, process amounts such as temperature and pressure of each part of the plant (analog input value). When is out of the limit range, the alarm window is turned on and an alarm message is output to the display device (printer) or the printing device. Further, in the control computer, the process amount is recorded, and calculation processing is performed based on the process amount, and these results are displayed on the display device automatically or at the request of the operator. Information such as status is provided to operators.

FIG. 16 shows the configuration of such a conventional plant monitoring device. The process amount (analog input, contact input, pulse input, etc.) used for controlling the plant 100 is sent from the control device 2 for controlling the plant 100 to the transmission device 3 via an optical fiber or the like. Then, these process quantities are transmitted and stored in the transmission buffer 5 in the control computer by the transmission input means 4 in the control computer at a predetermined transmission cycle. On the other hand, a process amount (actual analog input, actual contact input, actual pulse input, etc.) not used for controlling the plant 100 is detected by the process input / output device 6. It should be noted that the process point detection points (input points) of the plant 100 are numbered.

The analog input value stored in the transmission buffer 5 and the actual analog input value detected by the process input / output device 6 are read by the analog input means 7 at every designated cycle of the input point, and the plant input information table 12 is read.
The analog input means 7 determines whether the analog input value is a normal input or a defective input, and the quality code (code indicating whether the input is normal) is also stored in the plant input information table 1.
2 is updated and stored.

The contact input indicating the contact state of the plant 100 stored in the transmission buffer 5 is read by the contact input means 8 at a designated cycle for each input point and detected by the process input / output device 6 ( (Actual contact input)
Are read by the contact input means 8 when the interrupt state change notification from the process input / output device 6 is received by the contact input means 8, and the plant input information table 1
2 is updated and recorded, and the contact input means 8 determines whether the contact input is a normal input or a defective input, and the quality code thereof is also updated and recorded in the plant input information table 12.

Transmission pulse input (pulse count value) stored in the transmission buffer 5 and process input / output device 6
The actual pulse input (pulse count value) detected by is read by the pulse input means 9 at every designated cycle of the input point and updated and stored in the plant input information table 12, and whether the pulse input is a normal input or a defective input. Is judged by the pulse input means 9, and its quality code is also updated and stored in the plant input information table 12.

Thus, the plant input information table 12
Based on the process amount (primary input) stored in the calculation formula table 11, the calculation formulas stored in the calculation formula table 11 are used to perform calculation processes such as sum, difference, average, valid input determination, and logical operation by the internal calculation input means 10. The calculation result, that is, internal calculation value input (calculation value analog input, calculation value contact input)
Is also updated and stored in the plant input information table 12. Further, at this time, if the input amount of the process amount cannot be calculated due to a defect or the like, a defective code for setting the quality code of the internal calculation value input to "undeterminable" is set. FIG. 17 shows an example of sum / difference calculation average calculation and logical operation, FIG. 18 shows an example of auxiliary machine operating unit number calculation, change rate calculation, and FIGS. The sum / difference calculation is expressed as V = Ka.A. +-. Kb.B, etc., where V is the calculated value, Ka and Kb are specifiable coefficients, and A and B are primary inputs.
Now, let V = | AB | and let V,
Variables (identification codes) representing A and B are 4 with 6 digit code
BC006, 4BA019, 4BA021 gives 4
BC006 = | 4BA0019-4BA021 | (see FIG. 17), and these are stored as text images in the calculation formula table 11 as shown in FIG. A 6-digit code for the above variable, for example, "4B
The most significant digit "4" of "C006" indicates the unit number in the plant, the upper two to three digits "BC" indicate the classification of equipment, such as a boiler, etc., and the lower three digits are the input point number for the above equipment. Is shown.

In addition, the average calculation of two input points is performed in the calculation formula table 11, for example, 4DC000 = (4DA027 +
4DA029) / 2 or 4DC000 = AVE (4DA
027, 4DA029).

For logical operation, for example, logical product operation of 2 inputs (contact input A, contact input B), 4EC000 = AND (4AD001, 4A) on the calculation formula table 11.
D002, TIM = 60, BAD = 2).
4AD001 and 4AD002 represent variables of the contact inputs A and B, and TIM = 60 indicates that the calculated value contact input 4EC000 is defective when the value of the contact input A and the value of the contact input B do not match for 60 seconds. BAD = 2 makes the calculation value input defective when two or more inputs are defective.

In order to improve the reliability of the monitoring of the plant condition, the effective input determination calculation is performed with 2 to 4 for one detection point.
In the situation where the number of sensors is provided, it is to determine and read the effective plant state detection amount,
There are three cases of determination methods as shown in FIG. In case 1, the average value of valid inputs is used as the determination result, in case 2 the valid input with the highest priority among the valid inputs is used as the determination result, and in case 3 the valid input determination of 3 inputs, all 3 inputs are valid inputs. In this case, the average value of the two inputs with high priority is used as the determination result. In the case of Case 1, for example, 4BC005 = B on the calculation formula table 11.
V CASE1 (4BA014, 4BA016, SA =
70.0). Here, the variable 4BC005 represents the valid input determination result, and 4BA014 and 4BA01.
Reference numeral 6 represents inputs A and B, and SA = 70.0 is a deviation, and if the difference between inputs A and B is 70.0 or more, it cannot be determined.

FIG. 19 (a) shows a pattern of valid input judgment in the case of two inputs, and FIG. 19 (b) shows a pattern of valid input judgment in the case of three inputs.

In the following, the actual analog input having the analog quantity, the transmission analog input, and the calculated value analog input are generically referred to simply as the analog input, and the actual contact input having the contact state quantity (ON / OFF). , Transmission contact input,
The calculated value contact input is generically called simply contact input.

As described above, the plant input information table 1
Analog input values stored in 2 (temperature of each part, pressure, etc.)
Is compared with a preset alarm limit value in the alarm determination means 13 and deviates from the alarm limit value, or the contact input state is a preset alarm state (ON / OF).
In the case of F), the warning judgment unit 13 sends a warning window lighting request to the warning window output unit 14 and a warning message output request to the automatic message output unit 16. Further, when the analog input and the contact input are defective inputs, the alarm judgment means 13 similarly outputs the alarm window output means 1
A warning window lighting request is sent to No. 4, and a defective message output request is sent to the automatic message output means 16.
When the input point returns to normal (alarm → normal, defective → normal), an alarm window turn-off request is sent from the alarm determination means 13 to the alarm window output means 14, and a normal return message output request is issued to the alarm determination means. 13 is sent to the automatic message output means 16.

When the request for turning on or turning off the alarm window is sent to the alarm window output means 14, the alarm window output means 14 responds to the request and the alarm window 1 provided in the central monitoring room.
The designated window 5 is turned on or off. Further, when an alarm message output request, a defective message output request, or a normal recovery message output request is sent from the alarm determination means 13, the automatic message output means operates as the display device 1.
8. An alarm message, a defect message, or a return message is output via the printing device 19. FIG. 22 shows an example of a warning message, a failure message, and a normal recovery message displayed on the display screen of the display device 18. 23 shows an example of the display and print format of each message, and FIG. 24 shows an example of a defective state of defective input.

In the conventional plant monitoring device, the operator uses the display device 18 and the interactive input device 17 such as a touch screen or a keyboard to call up the graphic system diagram screen or execute various interactive functions. By doing so, the state of the plant can be monitored.

[0016]

In such a conventional plant monitoring device, when the internal calculated value input such as the calculated value analog input and the calculated value contact input is a defective input, that is, the judgment cannot be made, an alarm window is displayed. 22 and the defective message to the display device 18 and the printing device 19 are shown in FIG.
It is output in the format as shown in FIG. 23, and the operator can be alerted. However, in such a case, there were the following problems.

1) In the conventional monitoring device, since the primary input point and the like cannot be displayed based on the internal calculation value input, the operator can know the primary input and the like used for the internal calculation input. , I could only see it in documents such as calculated value analog specifications. Therefore, there is a problem that it takes time to search for a document, and it is unclear whether the document searched for is the latest version.

2) Even if the calculation type and the primary input point are known, the display device executes the interactive functions such as data display and data list by the interactive input device 17, and the current value and the state of the primary input point are displayed one by one. However, there is a problem that it takes time and effort to check what is causing the undecidable by manual calculation.

3) Even if the primary input point of the factor that makes the determination impossible is found, the conventional monitoring device has no means for canceling it. For example, when there are four primary input points, even if one of them is known in advance as a defective input due to inspection and adjustment on the sensor side, the operator can exclude that one point and calculate only the remaining three points. Even if it is decided to do so, there is no means for canceling it, and as a result, the internally calculated value input was still a defective input.

Therefore, due to the above-mentioned problems, the plant cannot be monitored smoothly, and it is a heavy burden on the operator.

The present invention has been made in consideration of the above circumstances, and an object of the present invention is to provide a plant monitoring device capable of reducing the burden on an operator and smoothly performing monitoring. To do.

1 shows the configuration of a first embodiment of a plant monitoring apparatus according to the present invention. The plant monitoring apparatus of this embodiment is different from the conventional plant monitoring apparatus shown in FIG. 16 in that a primary input search means 21, an input type determination means 22, and a primary input message output index flag storage means (not shown) are newly added. It is provided. The primary input search means 21 searches the calculation formula table 11 by using the input point number of the designated internal calculation value input as a key, and the calculation type of the designated internal calculation value input and all of the numbers used for the internal calculation value input. Find the primary input point of. The input type determination means 22 determines the input type such as whether the input point is internal calculation input or transmission input.
The primary input message output index flag storage means stores a primary input message output index flag 23 (hereinafter, referred to as index flag). This index flag 23 indicates whether or not to output a message in the n-line format with the input point number, name, calculation type, etc. of the primary input when the input is an internally calculated value input. Is given in advance. For example, if the value of the index flag 23 is "1", it is output, and if it is "0", it is not output.

The automatic message output means 16 determines whether or not the input point is an internally calculated value input according to an analog input from the alarm determination means 13, a defect such as a contact input, a warning, and a request to output a message for restoring normality. In the case of internal calculation value input, the index flag is referred to, and if the primary input point output is present (= 1), the primary input searching means 21 calculates the calculation type of the internal calculation value input and all of them. Obtain the input point number of the primary input, read information such as the current value of the primary input, quality code, etc. from the plant input information table 12 based on this input point number, and output a message with all the primary inputs together with the internally calculated value input.

Then, in FIG. 3A, the thin solid line is displayed in cyan, the broken line is displayed in red, the thick solid line is displayed in black, and the wavy line is displayed in white, as shown in FIG. 3B. Shows.

As described above, according to the first embodiment, when the internal calculation value input cannot be determined, when the internal calculation value input failure message is output,
Since the information of the primary input is added together and the message is output, the information of the primary input can be known at a glance on the display device 18 and the printing device 19, and the burden on the operator can be reduced.

Next, a second plant monitoring apparatus according to the present invention will be described.
The configuration of this embodiment is shown in FIG. The plant monitoring apparatus of this embodiment is the same as the plant monitoring apparatus of the first embodiment shown in FIG. 1, but has a primary input determination means 25, a primary input calculation exclusion / recovery means 26, a dialogue control means 27, and a calculation exclusion table. 28 is newly provided.

The interactive control means 27 displays the n-th line message in which the information of the primary input point is added to the defective message of the internally calculated value input point by the automatic message output means 16 while the display device 18 is being displayed. A request for the primary input calculation exclusion / return function selected by the operator via the interactive input device 17 such as the icon part (function selection area) on the screen of 18 and the interactive menu screen, and the touch screen, mouse, and keyboard. The primary input calculation excluding / restoring means 26 is called based on the above.

The primary input judging means 25 judges whether or not the designated internal calculation value input point and primary input point are subject to calculation processing based on the calculation formula table 11, and
When the input point is defective, it is determined whether the input point can be excluded from calculation depending on the calculation type. For example, the sum or difference calculation cannot be determined to be excluded from calculation, and the average calculation can be determined to be excluded.

The primary input calculation exclusion / restoration means 26 is called by the dialogue control means 27 to display a dialogue screen for primary input computation exclusion / restoration on the display device 18 in an interrupt window or the like, and a defective message is displayed. The operator is made to select and input the input point number of the primary input point and the internally calculated value input point via the interactive input device 17, and when the calculation exclusion / return function on the interactive screen is selected, The primary input judging means 25 is made to judge whether or not the primary input can be excluded from the calculation. If the calculation can be excluded, the internal calculation value input point and the primary input point are set in the calculation exclusion table 28, and further the internal calculation input is made. The calculation request is notified to the means 10 to be calculated, and the calculation result is displayed on the display device 18. When the internal calculation input means 10 receives the calculation request, based on the calculation exclusion table 28 and the calculation formula table 11, except for the primary input points to be excluded, for example, (A + B + C) / 3 becomes (B + C) / (B + C) / The calculation formula is changed as in 2 and the calculation process is performed again, and the calculation result is updated and recorded in the plant input information table 12.

FIG. 5 shows the configuration of the calculation exclusion table, and FIG. 6 shows an example of an interactive screen of an interrupt window in which the primary input point of the internal calculation value input is excluded from calculation.

Next, the operation of the second embodiment will be described with reference to FIGS.
Will be described with reference to.

First, while the alarm display screen is displayed on the display device 18, the "primary input calculation exclusion / return" icon in the icon part (function selection area) at the bottom of the screen is clicked on by an interactive input device such as a touch screen. Upon selection by the operator via 17, the dialogue control means 27 accepts the primary input calculation exclusion / return request and calls the primary input calculation exclusion / return means 26. (Hand mark in FIG. 6) Next, the primary input calculation exclusion / restoration means 26 displays the dialog window of the interrupt window and waits until the input point number and exclusion / return are selected and input.

The operator selects an input point to be excluded from the calculation on the screen by touching the primary input point and the internally calculated value input point in the defect message, and the interactive input device 1
The data is input to the primary input calculation excluding / restoring means 26 via 7. (Hand mark in FIG. 6) Also, by selecting either the calculation exclusion or the calculation return in the interrupt window by a touch operation or the like, input is made to the primary input calculation exclusion / return means 26 via the interactive input device 17. To be selected. (Hand mark in FIG. 6) In the primary input calculation excluding / restoring means 26, the primary input determining means 25 determines whether the input point input is the primary input point of the internal calculation value input, and the input point is the internal calculation. If it is the primary input point of the value input, in accordance with the calculation exclusion / return request, the internal calculation value input point and the primary input point are registered / deleted in the calculation exclusion table 28, and the processing result is displayed in the interrupt window. A recalculation request is made to the calculation input means 10.

The internal calculation input means 10 excludes the primary input point of the exclusion index based on the calculation exclusion table 24 and the calculation formula table 11, and in the case of an average calculation, (A +
The calculation formula can be changed from (B + C) / 3 to (B + C) / 2, the calculation process is performed again, and the result is updated and stored in the plant input information table 12.

If there is an input point where the normal state has returned from the defective state, the alarm judging means 13 requests the automatic message output means 16 to return to the normal state.

The automatic message output means 16 removes the defective message and outputs the normal recovery message to the display device 18 and the printing device 19 in response to the normal recovery message request. (Refer to an example of an alarm display screen in FIG. 8 which will be described later.)
