Description

  Embodiments described herein relate generally to a plant monitoring system and a plant monitoring method.

  In a power plant, a chemical plant, etc., a plant monitoring system for monitoring the state is used. In recent years, the decentralization of plant monitoring systems has progressed, and enhancement of functions other than the trend function for displaying the process change amount of the plant has been desired. For example, not only the monitoring data based on the operation status of the plant but also the data collection function for future plant efficiency improvement or the data collection and storage for the next plant plan.

  In a general distributed plant monitoring system, plant data is collected by a redundant server device (hereinafter referred to as a server) in order to eliminate loss of trend data and maintain continuity, and distributed client devices (hereinafter referred to as clients). Refers to and displays the trend data collected on the server.

  However, as described above, recently, the purpose of collecting plant efficiency improvement examination data, etc., as well as normal plant operation monitoring or data collection during periodic inspections, has been diversified, and the amount of trend data collected has been increasing. . Since a large amount of data can be collected and stored, it can be used for various purposes, so the amount of trend data collected may continue to increase. Continued to collect trend data corresponding to all applications using the current server alone will increase the server load and other functions such as server performance calculation, alarm processing, and transmission will cause processing delays and May cause non-conformity.

  In addition, with the expansion of monitoring purposes and applications, the trend data display setting items increase, the number of items that can be set by the conventional plant monitoring device exceeds the limit, and there are too many items to be displayed. It may take time to find the settings. As a result, the ease of use required for the plant monitoring device is impaired, and particularly when the emergency operation is performed while viewing the trend data display due to a large change in the plant.

  Therefore, in order to prevent data loss in the event of a server failure, data is collected and stored at the server when it is operating normally in the plant monitoring and control system. There is a method in which the output device saves data on behalf of the server function when the server is stopped, and the collected, calculated, and saved data is sent to the server when the server becomes normal, and the missing data is supplemented. . (For example, see Patent Document 1)

  As for the trend data display method, the assignment method is a selection method from the list, and there is a method of dragging on the display screen list and dropping it on the trend screen displayed at the same time. (For example, see Patent Document 2)

JP 2007-233891 A JP 2009-301260 A

  Although the above plant monitoring and control apparatus is effective as a means for preventing data loss, it is not possible to increase the number of trend data items without loss required as background technology.

  In addition, the display setting method is effective as a method that allows easy assignment, but it is impossible to judge all the groups to be opened in order to quickly search from a large number of setting groups. In a conventional plant monitoring system, when trend display is performed by a client, individual settings are made while referring to items collected by a server. For this reason, if you want a trend that is not collected by the server, you must make a collection registration on the server and then request a reference from the client.

  Further, in a large-scale system having a plurality of clients, the time and effort required to set each client is increased. In addition, a plurality of similar trend groups may be set, and the trend group may be enlarged when monitoring the plant, and it may not be easy to select and call a necessary trend group.

  Furthermore, it is generally difficult for trend groups to determine collection items from group names. For this reason, it is impossible to determine whether the target trend group is present unless all levels are opened or the trend is displayed. As a result, selection and display may be repeated many times until the target trend group is reached.

  An object of the present invention is to provide a plant monitoring system and a plant monitoring method that make it easy to set a group of plant data set by a first client computer using a second client computer.

  The plant monitoring system of the embodiment includes a server computer and first and second client computers. A first storage unit that stores a plurality of plant data that is output from a detection unit that detects the state of the plant and that represents the state of the plant, and a plant that belongs to each of a plurality of first groups of plant data; A second storage unit storing a first list of identification information for identifying data, and a plurality of units stored in the first storage unit based on the first list stored in the second storage unit Are stored in the plurality of first groups, the third storage unit that stores the plurality of first groups of the divided plant data, and the third storage unit. And a first display unit that displays a plurality of first groups of plant data.

Based on the list of 2, the first storage unit is referred to, a generation unit that generates a second group of the plant data, and a second group of plant data generated by the generation unit are stored A fifth storage unit; and a second display unit that displays a second group of plant data stored in the fifth storage unit. The second client computer displays a second group of plant data stored in the sixth storage unit, and a sixth group that stores the second group of copied plant data, and a third group that displays the second group of plant data stored in the sixth storage unit And a display unit. At least one of the server computer and the first and second client computers refers to the fifth storage unit, copies the second group of the plant data, and stores it in the sixth storage unit. A copy section is further stored.

The plant monitoring system 100 according to the present embodiment has the following features.
(1) Copy of group information in the system Group information (for example, C11 group information 43-1) in the system can be copied. For example, there is a case in which the trend data display of the C11 group information 43-1 can be performed by the n client 50 from one client 40. In this case, the C11 group information 43-1 is copied by one client 40 and pasted to the display data processing unit 501 of the n client 50. By selecting the pasted group in the display selection unit 560 of the n client 50, the C11 group information 43-1 similar to the display screen of the one client 40 is displayed on the display unit 550.

  The C1 group information 34-1 set by the server 30 and the group information 44-1 set by one client 4011 may be copied to the display data processing unit 501 of the n client 50. The C1 group information 34-1 and the 11 group information 44-1 can be displayed as trend data.

  The one client 40 can also copy the C1 group information 34-1 and the n1 group information 54-1 to the one client 40. The C1 group information 34-1 and the n1 group information 54-1 can be displayed as trend data.

  As described above, the C11 group information 43-1 set to refer to the data of the server 30 by one client 40 is sent to other clients (for example, the n client 50) as group information by the collection / edit operation unit 470. By pasting, the same group information (C11 group information 43-1) can be displayed on another client.

  As a result, trend data with exactly the same group information can be easily set in another device (client, etc.), eliminating errors such as incorrect ordering, range, collection cycle, and group name. It is possible to reduce the setting accuracy and setting time.

(2) Collecting Trend Data at Client Basically, in the plant monitoring system 100, the data collected by the server 30 is displayed by reference at each client. On the other hand, like the server 30, trend data can be collected by each client. The collected trend data is accumulated in the individual trend data storage units 42 and 52 and utilized.

  Even if an item that is not collected by the server 30 is data that exists in the network 60, the one client 40 can arbitrarily select and collect and set it in the individual trend data storage unit 42. As a result, a plurality of groups of 11 group information 44-1 to 1n group information 44-n unique to one client can be created. Further, items can be arranged and distributed as compared with the case where all the collection and storage processes are performed by the server 30.

  As described above, by enabling arbitrary collection by all clients, the number of data collection items increases in proportion to the number of clients, so that more data can be collected and stored. Further, the processing load on the server 30 can be reduced by organizing the collection items and distributing the collection. For this reason, it is possible to improve the processing speed of performance calculation and to reduce the influence level at the time of failure.

(3) Copying Trend Data Collected by Client As shown in (2), each client can have group information unique to each client in the individual trend data storage units 42 and 52. Therefore, the group information can be copied and pasted on the client by the collection / edit operation units 470 and 570.

  Since the data can be collected without distinguishing between the server and the client, the display data processing unit 401 in one client 40 has various group information (for example, C11 group information referring to the collected data of the server 30, and one client 40 is unique. 11 group information 44-1 to 1n group information 44-n and n1 group information 54-1) collected and set by the n client 50 can be customized.

  As described above, group information is collected and stored as the same group information in a plurality of clients. As a result, even if data is lost due to a client failure, the lost part can be easily complemented by copying it as group information after recovery from the failure.

(4) Trend list display Copy the group information (trend group) to have the same group settings to increase the trend data collection items in (1) to (3) or to complement each other between clients. Was shown to do. The item list 311, 411, 511 accompanying the server trend list 310, the one client trend list 410, and the n client trend list 510 can be collectively displayed on the server 30 so that these trend groups can be centrally managed. Manage server trend list 310 etc. in matrix format

  Since all trend lists can be displayed on the server, it is easy to check whether there is a group that has already been set somewhere when trying to make a new setting.

  As a result, similar settings can be prevented. This prevents the trend group from becoming too large and reduces the load on each device.

(5) Trend list editing The collection / edit operation unit 370 selects and edits an arbitrary group from the trend lists 310, 410, 510 and item lists 311, 411, 511 in the server 30, the first client 40, and the n client. it can. The edited trend list 310 or the like can be replaced with the pre-edited trend list 310 or the like in the server 30 or the like by selecting the server 30, 1 client 40, or n client.

  By performing editing operations on a centrally managed list, the setting status of the entire system can be confirmed. In the past, setting work at the location where each client was installed was essential, and it can be expected to omit movement and prevent setting omission.

  As described above, it is easy to correct or integrate settings on clients that have become similar settings. This makes it easy to organize trend collection items and simplify maintenance.

(1) In the plant monitoring system 100, the setting contents when the trend data collected by the server 30 is referred to and displayed by the clients 40 and 50 are registered as a trend group (group information) and copied to the other clients 40 and 50. it can. Therefore, it is possible to prevent the labor for individual setting and the generation of similar trend groups. In addition, the enlarged group can be managed in a list by the server 30 in a matrix format and refined search can be performed. As a result, the necessary trend group can be easily reached, and unnecessary operations are reduced.
