Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention is a power generation system that monitors the operation of a large-scale power generation plant composed of multiple units from the screens of multiple man-machine input/output devices. It relates to a plant operation monitoring device.

(Prior Art) Conventionally, when operating a power generation plant, operators manually set the voltage standard to be output to the power supply, opened and closed valves, etc. from a control panel on site.

However, with the development of computer systems in recent years.

Centralized monitoring systems, which centrally monitor large-scale plant information using a central man-machine input/output device, have become widely used and are helping to reduce the burden on operators. The objective of such a system is efficient operation by as few operators as possible using as few man-machine input/output devices as possible. However, if the scale of the plant is large, it is still common to use around 3 to 10 man-machine input/output devices for monitoring. Furthermore, recently, systems have been introduced that use these central man-machine input/output devices not only to monitor the plant, but also to set control output standards and perform setting operations such as opening and closing valves, thereby saving labor. Not a few.

For example, when using a neutral particle injection device (hereinafter referred to as NBI) as a secondary heating device for nuclear fusion, about 4 to 15 NBI units are operated individually. in this case,
In addition to monitoring multiple ion source power supplies and beamline thermocouple signals for each unit.

Many setting operations must be performed, such as setting the power source standard, gas flow rate, and timing of the power source 0N10FF.

However, conventional man-machine input/output devices using switches and buttons are inefficient in terms of manpower and space, especially as the number of units increases.

Therefore, devices equivalent to conventional switches, buttons, and indicator lamps are efficiently arranged on the screen prepared for the man-machine input/output device, and settings can be made from there, making it possible to centrally monitor operation of the power plant. A monitoring device has been proposed.

The 16th conventional example of such a power plant operation monitoring device
As shown in the figure.

In the figure, the voltage sent from each unit of the plant,
Signals such as current, flow rate, temperature, etc. are input to the plant data input means 2 of the power plant operation monitoring device 1. On the other hand, in the data processing section Di (i=1-m), the display data selection means 3 selects screen information data to be displayed on the man-machine input/output device M1 (121 to m) from the screen information table 4, and Based on the information data, input data is selectively input from data input means 2 and passed to man-machine display means 5.

The man-machine display means 5 converts this into display data,
Data is displayed on the man-machine input/output device Mi.

Further, when inputting set values such as voltage, current, flow rate, temperature, etc. of the plant unit or screen switching from the man-machine input/output bag NM1, the processing is performed by the man-machine input means 6 and the set value input means 7. Otherwise, it is distributed to the screen switching means 8.

When entering set values such as voltage, current, flow rate, temperature, etc.
In the case of input for 0 screen switching, which is output from the set value input means 7 to each unit of the plant via the plant data output means 9, the screen switching means 8 inputs the screen type to the screen information each time the screen changes. It is stored in the table 4 and requests the man-machine display means 5 to update the display.

The man-machine display means 5 converts the plant data and screen information into display data and displays the data on the man-machine man output device MMi.

The data processing unit Di performs such processing in parallel, so depending on the operator's screen selection, the information of a specific unit of the plant can be displayed simultaneously on multiple man-machine input/output devices, and the plant It is also possible to display information of multiple units on one man-machine input/output device EMi.

(Problem to be Solved by the Invention) However, according to the above-mentioned conventional device, when information regarding the same unit is displayed on multiple man-machine input/output devices, operations on the same device from different man-machine input/output devices cannot be performed simultaneously. Done.

There are problems in that multiple operators compete with each other in operation, making smooth operation impossible and causing inconsistent operation of each unit. In addition, if all units are displayed together on one man-machine input/output device, regardless of whether each operator is operating or not, this may lead to misjudgment when operators monitor plant operation. There were problems such as causing problems.

Accordingly, the present invention has an object to operate multiple units of a plant from multiple man-machine input/output devices without losing the degree of freedom of the units and the corresponding man-machine input/output devices that monitor the operation. It is an object of the present invention to provide a power generation plant operation monitoring device that allows operation to always focus on any unit without being confused by information of other units, and that does not cause operation conflicts.

[Structure of the Invention] (Means for Solving the Problems) The power generation plant operation monitoring device of the present invention provides unit acquisition exclusion storage that stores a combination of the identification number of the man-machine input/output device and the identification number of the corresponding acquisition unit. A table, acquisition exclusion unit input means for reading the identification number of the man-machine input/output device requesting acquisition exclusion, unit identification number, and acquisition exclusion request type, and a request read from the acquisition exclusion unit input means for acquiring the unit When making a request, the identification number of the requested unit is written in correspondence with the identification number of the man-machine input/output device, provided that the requested unit is not in the unit acquisition/exclusion storage table; On the condition that the unit has been acquired by the requested man-machine input/output device, the identification number of that unit is deleted from the unit acquisition exclusion storage table, and if the above conditions are not met, the request is rejected. When data related to unit setting operations are input from the man-machine input/output device, the acquisition/exclusion determining means refers to the unit acquisition/exclusion storage table and determines whether the unit has been acquired by the man-machine input/output device. and a setting operation permission/impossibility determination means for checking whether the request unit is available and accepting a setting operation request only for the unit acquired by the requesting unit input/output device.

(Function) According to this power plant operation monitoring device, any unit is always acquired by one man-machine input/output device, or is excluded from all man-machine input/output devices, and any unit The man-machine input/output device is either not acquiring any units or acquiring one or more units.

At this time, the set value of only one acquired unit can be manipulated from any man-machine input/output device.

As a result, the operator can arbitrarily acquire units that have not been acquired elsewhere and monitor the operation of the unit without having to deal with other operations.

(Embodiment) Fig. 1 is a functional block diagram showing an embodiment of the power generation plant operation monitoring device according to the present invention. Signals such as voltage, current, flow rate, temperature, etc. sent from each unit of the power generation plant, which is a constituent country, are shown in Fig. 1. is input from the plant data input means 2 of the power plant operation monitoring device 1 to the display data selection means 3 of the data processing section Di. This display data selection means 3 selects the plant unit number and input data to be displayed on the man-machine input/output device M1 based on information such as the screen number stored in the one-screen information table 4. Select and input from. The data selected by the display data selection means 3 is displayed moment by moment on the man-machine input/output device Mi by the man-machine display means 5.The content displayed on the elbow of the man-machine input/output device includes the above-mentioned data. In addition, unit acquisition, exclusion state preservation table 1
“Which man-machine input device Mi is currently stored in 3?”
Information about which units you have acquired will also be displayed.

The second WI is the constituent country of the unit acquisition exclusion storage table 13, and is the identification number 21. of the man-machine input/output device Mi.
It consists of an identification number 22 and an END code 23 of the acquisition unit. The unit acquisition exclusion storage table 13 is
All the identification numbers 22 of the units acquired by the man-machine input/output device Mi are stored in order of the man-machine input/output device. For example, if the identification number 21 of the man-machine input/output device is C1, it is U□Work.

... n0 units of υznz are each acquired.

Furthermore, if the identification number 21 of the man-machine input/output device is C2, U21. . . . n2 units of Us n2 are each acquired. Here, one unit can only be acquired by one man-machine input/output device, so U, ≠U1□≠...υ2□≠...
≠Umnm. Note that there may be units that have not been acquired in any CRT.

After the acquisition and exclusion requests, requests for unit number 1 screen switching, and setting operation data for the unit inputted by the operator or the like from the man-machine input/output device NMi are received by the man-machine input means 6, Processing is divided into acquisition/exclusion unit input means 10, screen switching means 8, or setting value input means 7 according to the input conditions.

An operator requests to operate the plant's unit N from his/her man-machine input/output device elbow by "acquiring unit N."
Or, if unit N has already been acquired and operated, but it is no longer necessary and you do not want to exclude it, as "unit N excluded", man-machine input/output device iN
i, but in this case the input information will flow to the acquisition/exclusion unit input means 10 via the man-machine input means 6.

FIG. 3 is a flowchart of the acquisition/exclusion unit input means 10 when there is an acquisition/non-M request from an operator or the like.

Receive an input request from the man-machine input means 6 (31)
, write the identification number 21 of the man-machine input/output device to memo+)H (32), write the unit identification number to memory N (33), and read the acquisition/exclusion request type (
34), requests the acquisition/exclusion request determining means 12 to make a determination (
35) The information output from the acquisition/exclusion unit input means 10 is stored in FIFO (First
t In First 0ut) 11, the information output from FIFO II is input to the acquisition/exclusion determining means 12, where it is compared with the information stored in the unit acquisition/exclusion storage table 13. , it is determined whether the conditions for the acquisition exclusion request are met.

When a request to "acquire unit N" is issued from a man-machine input/output device, if the unit has already been acquired by any other man-machine input/output device, the condition is not met, and the acquisition/exclusion determining means 12 Doesn't do anything. However, if the unit N has not been acquired by any other man-machine input/output device, the condition is satisfied, and the information on unit N acquisition is written in the unit acquisition exclusion storage table 13. In addition, when a request to exclude a unit N is issued by the man-machine input/output device old, if the unit N has been acquired by the requested man-machine input/output means Mi, the condition is satisfied, and the acquisition/exclusion determining means 12 deletes unit N from the unit acquisition exclusion storage table 13.

However, if the unit N has not been acquired by the requested man-machine input/output device, the condition will not be met, and the request to “exclude unit N” from the man-machine input/output device will be rejected.

FIG. 4 is a flowchart of the acquisition/exclusion determination means 12 when a determination request is received from the acquisition/exclusion unit input means IO. Here, the table shown in FIG. 2 is used to determine whether the request can be accepted. First, a judgment request is received from the acquisition exclusion unit input means 1o (41
), determine whether the request is for acquisition or exclusion (42)
. When it is determined that it is an acquisition request, processes 43 to 52 are executed to process the acquisition request for unit N input from the man-machine input/output device elbow.

That is, in order to check whether the unit N for which an acquisition request has been made is already registered in the unit acquisition exclusion storage table 13, the acquisition/exclusion determining means 12 first sets the identification number of the man-machine input/output device M1 to J=1. (43), then it is checked whether the processing has been completed for all man-machine input/output devices (44), and if it has not been completed, the unit acquisition exclusion storage table 13 of the own man-machine input/output device is
There is no need to check J, so it is determined whether J is its own. If J is not its own, in order to sequentially check the identification number 22 of the unit acquired by the man-machine input/output device, set =l first (47), and if it is not an END code, enter (48). N), reads the registered unit identification number UJK (50) and checks whether it matches the requested unit N (51). If the result is a mismatch, add 1 to = (49), and then check with the unit identification number acquired by the J=1st man-machine input/output device. While repeating this process, if the END code is found (Y of 48), in order to check the unit acquired by the next man-machine input/output device, J = J + 1
Repeat the process as

In this way, the unit identification number acquired by all man-machine input/output devices is compared with the requested unit identification number,
If all of them do not match and the result is END (Y in 44), the identification number of the requested unit is written in the unit acquisition/exclusion storage table 13, and the process in the acquisition/exclusion determining means 12 is ended.

On the other hand, when it is determined that the request is an exclusion request in the process 42, unlike the process at the time of the acquisition request, the requesting man-machine input/output device Mi
Processes 57 to 62 are performed only for the table. Here, the method for determining whether or not the identification number of the requesting unit is included in the table is the same as the acquisition request processing, but if it is included, in step 62, man-machine input/output of the unit acquisition exclusion storage table is performed. The unit identification number N is deleted from the acquired unit of the device.

When an operator inputs a screen switching request from the man-machine input/output device Mi, the input information such as the screen number is stored in the screen information table 4 by the screen switching means 8 via the man-machine input means 6. Ru.

While adding +1 to = (96°97.98), the stored unit identification number UJK is read and it is checked whether it includes the requesting unit identification number N (100). If it is not included, the request for setting operation will not be accepted, but if it is included, a request is made to the plant data output means 9 to output the set value of the unit.

FIG. 8 shows the processing procedure of the display data selection means 3 when a display update request is received from the plant data input means 2. After receiving a display update request from the plant data input means 2 (111), the screen number is read from the screen information table 4 (112), display items are selected based on this information (113), and a display request is made to the man-machine display means 5. (114).

As described above, by attaching the unit in charge to the man-machine input/output device that the operator operates, the operator can operate the unit without worrying about interrupt operations from other man-machine input/output devices Mi. Able to drive consistently. In addition, regarding the operation system, there are
