Description

  The present invention relates to a plant information management apparatus and a plant information management method for managing a data group related to a plant.

  In order to operate the plant stably and safely, people engaged in the plant need to access the plant information from various viewpoints depending on their roles.

  For example, the operator monitors whether heating, cooling, and reaction are being performed on the correct raw material under the correct conditions, mainly using piping and instrumentation diagrams. The process staff mainly uses a process flow diagram to determine whether a product is correctly manufactured by comparing with theoretical values, for example, referring to past data, and is considering improvement of the process. The quality staff is mainly based on the sampling results of the product, whether the target quality has been reached, whether there is a quality defect, what is the cause of the quality defect, what is the method for preventing the quality defect, etc. Are considering. Maintenance personnel pay attention to the devices scattered in the plant. Mainly in the systematic hierarchy (plant hierarchy), whether the equipment has not failed, does not have a behavior indicating a sign of failure, or is overloaded. We are studying whether we are not concentrating on a specific device or how to perform maintenance on the next device. In addition, the manager reports from the person in charge about whether the products are shipped with the target quality on time, whether there are any accidents or overwork, and whether the equipment in the plant has failed. Mainly manage the whole.

It is a figure which shows the structure of the plant information management apparatus of one Embodiment, (a) is a block diagram which shows the structure of the field control system to which a plant information management apparatus is applied, (b) is a figure which shows the structure of a terminal device. The figure which illustrates a plant correlation diagram. The figure which shows the example of a display screen by a display means.

  Hereinafter, an embodiment of a plant information management device according to the present invention will be described.

  Fig.1 (a) and FIG.1 (b) are block diagrams which show the structure of the field control system to which the plant information management apparatus of this embodiment is applied.

  As shown in FIG. 1A, the field control system includes field controllers 2, 2,... Distributed in a plant and field devices 1, 2,. The operation monitoring device 3 for monitoring the operation, the server 4 for storing process data (history data) and the like, and the terminal device 5 for accessing various data related to the plant are provided. The field controllers 2, 2,..., The operation monitoring device 3, the server 4, and the terminal device 5 are connected to each other via a network 6.

  As shown in FIG. 1B, the terminal device 5 stores, for each role of the staff, a storage unit 51 that stores a group of data (objects) related to the plant and the relationship between the data stored in the storage unit 51. A definition means 52 to be defined, a reception means 53 that receives an input of a definition by the definition means 52, and a display that displays data stored in the storage means 51 in a form that is defined by the definition means 52 and that corresponds to the association for each role. Means 54. Further, the terminal device 5 is provided with a communication unit 56 that performs communication via the network 6.

  FIG. 2 is a diagram illustrating a plant correlation diagram defined by the definition unit 52 for the objects stored in the storage unit 51. The plant correlation diagram shows the data related to the plant, for example, the data necessary to represent the operation state of the plant, and if there is a relationship between the objects, the objects are connected by wiring. It is a figure which shows relevance.

  Here, the object is a collection of data, including setting information necessary for obtaining data values, for each data. For example, a collection destination data source, a collection method, a collection timing, a data storage method, an arithmetic expression, a calculation timing, and the like are included.

  The role name (owner) of the person who sets the relationship between the objects can be added to the object and the wiring. In FIG. 2, “(OP)” represents an operator, “(maintenance)” represents a maintenance worker, and “(ST)” represents a staff as a role name (owner).

  In addition, as shown in FIG. 2, a type indicating a related attribute can be set for the wiring. As shown in FIG. 2, it is possible to specify attributes related to objects such as an “aggregation relationship” attribute indicating ownership and an “inheritance relationship” attribute having a parent-child relationship and a child taking over parent information.

  As described above, by using the role name (owner) and the attribute, it is possible to express the relationship between the complicated data (objects).

  Such a correlation diagram is created in accordance with an operation by the user via the accepting unit 53. The user can freely specify the relationship between objects by setting objects and wiring for each role. When creating the correlation diagram, the correlation diagram may be displayed on the screen of the display 7 so that the correlation diagram can be created and edited by an operation on the screen.

  In setting the wiring, a rule that can omit the operation for setting the wiring between the individual objects may be defined in advance in the defining means 52. For example, if you define a rule that “Set a wiring that is owned by maintenance personnel between the field device and the data that constitutes the specifications of that device,” such wiring for each field device is defined. The input operation to set becomes unnecessary. When a rule exception occurs, an input operation for correcting each wiring may be performed.

  The display means 54 displays the object data stored in the storage means 51 on the screen of the display 7 in a display form based on the correlation diagram.

  FIG. 3 shows an example of a display screen by the display means 54.

  In this example, a screen for an operator generated in accordance with the correlation diagram of FIG. 2 is shown. As shown in FIG. 2, the correlation diagram includes “raw material valve A”, “raw material pump A”, “reaction tank A”, “product valve A”, and “product pump” as data aggregated in “reactor A”. A "is shown. On the other hand, as shown in FIG. 3, on the display screen, “raw material valve A”, “raw material pump A”, “reaction tank A”, “product valve A” By arranging “product pump A”, it is indicated that these are data related to “reactor A” and that there is an aggregation relationship.

  The operator can acquire corresponding data by operating (for example, clicking) an icon on the display screen, or can expand and display other data related to the corresponding data. When data acquisition is instructed by an operation on the screen, for example, the data (data value) is acquired via the communication unit 56 and the network 6.

  In this way, on the screen for the operator, the display means 54 searches for the wiring whose owner is the operator among the wirings in the correlation diagram, and reflects only the relevance between objects whose wiring owner is the operator on the screen. . This enables efficient access to data necessary for the operator. Similarly, on the screen for maintenance personnel, the relevance is reflected on the screen only when the wiring owner in the correlation diagram is the maintenance personnel. In the screen for the staff, only when the wiring owner in the correlation diagram is the staff, the relevance is reflected on the screen.

  As described above, according to the plant information management apparatus of the present embodiment, it is possible to acquire different ways of displaying data suitable for each role by using the plant correlation diagram.

  Since all role screens are created based on the same application, all data stored in the storage means 51 can be easily accessed by changing the definition in the definition means 53, that is, the plant correlation diagram. It becomes. For this reason, the same data can be effectively used across roles, and the burden of engineering work can be reduced. Even when a change occurs in the plant, the range of influence can be easily determined by following the relationship between the objects. In addition, even if a change occurs in the plant, only the correlation diagram needs to be corrected, so there is no burden on engineering work.

  Next, the search means 55 searches for all objects stored in the storage means 51. For example, when a new object is desired to be added, a search across the roles is performed on the plant correlation diagram. As a result of the search, if the object is already defined in another role, the object can be used for the role only by adding an owner. As a result, it is possible to eliminate the waste of duplicate data collection, reduce the extra overhead for the entire system, and handle the data efficiently.

  As described above, according to the plant information management device and the plant information management method of the present invention, the relationship between data is defined for each role, and in accordance with this definition, in the storage means in a form corresponding to the relationship for each role. Since the stored data is displayed, it is possible to easily provide a different display form for each role by creating or changing the definition of the relationship between the data. Therefore, the engineering burden can be greatly reduced.

  The scope of application of the present invention is not limited to the above embodiment. The present invention can be widely applied to a plant information management apparatus and a plant information management method for managing a data group related to a plant.
