Description

  The present invention relates to a monitoring operation apparatus that can be used by an operator for operation of a plant, and particularly relates to a human interface thereof.

  In a distributed control system, a single or a plurality of monitoring operation devices are connected as nodes to a communication network, and the monitoring operation devices are used by a plurality of operators. Information necessary for operation (group information, trend information, user graphic screens, etc.) is registered in the monitoring operation device, and there are setting items that are used in common by all operators. Some items are used. In the current monitoring operation device, multiple group information, trend information, and user graphic screens can be defined. However, since each setting item is attached to the monitoring operation device node, each operator sets his / her setting necessary for monitoring / operation with a registration number ( Or registered name) and used as appropriate.

  The invention disclosed in Patent Document 1 provides a field control system that can enable efficient operation of a monitoring control device. There, a communication between a field controller distributed in the plant and the field controller via a control bus makes it possible to perform a monitoring control device that performs monitoring control of the plant and an operation on the monitoring control device. The operation terminal device is divided into receiving operation terminal devices, the operation terminal device authenticating an operator for the operation terminal device, and an access indicating a range of access authority of the authenticated operator for each monitoring control device An access information acquisition means for acquiring information, and the operation terminal device discloses a technique for accepting the operation when there is the access authority according to the access information acquired by the access information acquisition means.

JP 2011-118573 A

  As shown in Patent Document 1, there are many inventions in which an operator, that is, an operator is authenticated at the time of login and various operations are secured using the access authority of the operator. This function is effective when the operator writes the point data rather than reading the information.

  On the other hand, each operator has a request that he / she wants to memorize a setting necessary for monitoring / operation by a registration number (or registration name) and use it for reading information. In a small-scale plant, the number of operators and equipment is small, so there are not many operational problems. However, in the case of a large-scale plant, the number of operators and the number of monitoring operation devices are large. The problem of being confused with operator information and driving with reference to incorrect information remained unresolved.

  The present invention realizes a mechanism that can realize a desired operation without relying on an operation monitoring device for plant operation, that is, to any monitoring operation device, using a normal personal database. .

The present invention is a monitoring operation device used for plant operation,
Definition data associated with the monitoring operation device;
Operator-specific database area defined for each operator,
Authentication means for log-in authenticating the operator;
Download means for dropping the authorized operator dedicated database from the upper server into the operator dedicated database area;
Comparing means for comparing the dropped operator-dedicated database and the definition data attached to the monitoring operation device or the monitoring operation device read from the server with a time stamp indicating a definition date and time,
The monitoring operation device displays a warning to the operator when there is newer definition data associated with the monitoring operation device than the time stamp of the operator dedicated database.

  Furthermore, in this monitoring operation device, when the operator-dedicated database is updated, the monitoring operation device includes an uploading unit that stores the operator-dedicated database from the monitoring operation device to the server.

  According to the present invention, it is convenient if the operator can operate with his own settings and the latest settings without being aware of the monitoring operation device. Since the monitoring operation device used by the operator for driving is often not fixed, the operator can always operate in the same environment regardless of where he / she sits.

  Also, when link destination information is updated, there is a possibility that the device or equipment has changed, so using old definition information will lead to erroneous operations or accidents, so notify the operator that link destination updates have been updated. To do. Since these pieces of information are all associated with the operator, when the operator starts an operation with an arbitrary monitoring operation device, the operator is identified by the biometric authentication device or the like, and the favorite information of the operator is stored in the server (external storage device or the like). You can download and upload from.

It is a figure which shows the whole structure of the control system concerning this invention, and positioning of the monitoring operation apparatus. It is an illustration figure of the operator exclusive use database concerning embodiment of this invention. It is an illustration figure of the definition data accompanying the monitoring operation apparatus concerning embodiment of this invention. It is a chart which shows the process transition between the monitoring operation apparatus of this invention, a server, and between other monitoring operation apparatuses.

  Embodiments of the present invention will be described below with reference to the drawings. First, FIG. 1 shows the overall configuration of the control system according to the embodiment of the present invention and the positioning of the monitoring operation device. This system is a system that contributes to control of factories, buildings, and other plants, and has a server 1 at the upper level, and the monitoring operation devices 10-1 to 10-n are the gist of the present invention. These take the configuration of a client server and may be in the form of cloud computing.

  There is a controller 5 that controls field devices, and is connected to various input / output devices (not shown).

  The server 1, the monitoring operation device 10, and the controller 5 are connected via a communication network. In the figure, the upper network 3 and the lower network 4 are hierarchically described. However, a flat or ring network may be used without distinguishing upper and lower networks. Moreover, it does not ask | require wired radio.

  Now, a part of the contents of the monitoring operation device 10 is described. Definition data 11 is attached to the node of the monitoring operation device. The monitoring operation devices are often distributed corresponding to the subsystems of the plant equipment, and various information corresponding to the target subsystem is stored.

  An operator dedicated database storage area 12 is prepared in the monitoring operation device 10. This is an area where a certain operator sits on the monitoring operation apparatus 10 and downloads his / her “favorite” data from the server 1 after authentication.

Next, the monitoring operation device 10 is provided with a reading device 13 such as a camera for reading the fingerprint, voice print, iris and other biometrics of the operator. In the figure, biometric authentication is performed when the operator 9 logs in close to the reading device 13. Note that the authentication is not limited to biometric authentication, and may be authentication using a password, an IC tag, or the like.

The authentication means, the download means, the database comparison means, and the upload means are realized by software, and their functions will be described later. As described above, the monitoring operation device is configured by a computer device such as a PC. It does not matter whether it is a desktop type or a tablet type.

  In this example, FIG. 2 shows the contents of a favorite database of an operator stored in the operator-dedicated database area 12, and FIG. 3 shows the definition data associated with the monitoring operation device as monitoring operation devices 1 and 3 (node names HMI1 and Contents of HMI3).

First, the operator-dedicated database in FIG. 2 is configured in a table format.
The data IDs are sequentially arranged as 1, 2, 3, 4 and the link source information of the data is described by the node name / group number. “/” Is a delimiter.

In this example, the information of the group display for monitoring is formed. The included point names are listed by tag @ parameter names, and finally a time stamp indicating the definition date and time is added.
The time stamp is, for example, the number of seconds counted from January 1, 1970, and “1000000000” is set to 1:46:40 on September 9, 2001,
“141123560” indicates 20: 6: 00 on September 20, 2014.

In ID1, the group 100 of the HMI3 node is linked, and the HMI3 / group 100 information is specified to be read according to the ID1. The breakdown data points are
A tag @parameter such as A123 @ PV and V99 @ PV is indicated. The time stamp is 1,000,000,000. In ID2, HMI1 / group 4 is linked, and the tag @ parameter is as shown. Description of the following IDs is omitted.

Next, in FIG. 3, when looking at the definition data attached to the HMI 1, groups 1 to 4 are described here. The tag @ parameter of each group constituent point is listed, and a time stamp is added. This represents the definition date and time, and when the definition work is completed and saved in a file or uploaded to the server, the date and time is recorded in the time stamp.
The data of HMI2 is skipped, and the definition data associated with HMI3 is shown in the lower table.

Now, when an operator is Mr. C and approaches the monitoring operation device of the HMI 1 as shown in FIG. 1 and can log in by receiving biometric authentication, the operator dedicated database can download the favorite 2-C from the server 1. Here, the operator C tries to display the self-favorite group 1 display as shown in FIG. At that time, the definition data is compared and collated from the HMI3 / G100.
Then, the self time stamp is 1,000,000,000 (FIG. 2), the time stamp of HMI3 / G100 is 14113243560 (see the lower part of FIG. 3), and it can be seen that the definition data at the link source is newer. This is why a circle is added to ID 1 in FIG.

  This means that the definition data associated with the monitoring operation device HMI3 has been updated due to a change in the equipment environment, and there is a problem for the operator C to continue operation monitoring as it is. Therefore, the monitoring operation device 10 displays a “warning” message to that effect on the screen. It should be noted that the image will be easy if this screen has the same functions as a Web browser.

  Other than ID2, if the link source information (HMI1 / G4) is not inconsistent, or if the time stamp of the operator-dedicated database is new, the operator interprets that there is no update of the equipment environment, etc. Can proceed.

  Next, FIG. 4 illustrates a chart showing process transitions between the monitoring operation device and the server and between other monitoring operation devices according to the embodiment of the present invention. In this example, as shown in FIG. 1, the description will be made from the point where the operator 9 logs in to the monitoring operation device 10 of the HMI 1 and starts the operation work.

  First, biometric authentication of the operator 9 is performed and logging in (step S10 in the figure). This is the execution of the authentication means. If the user can log in with the authentication OK, a request for downloading the dedicated database of the operator C is made to the server (S11). When a response comes (S12), the operator-dedicated database that is the favorite 2-C is stored in the monitoring operation device 10. The above is the execution of the download means. Although error cases such as authentication failure or download failure are omitted, retry may be performed as appropriate.

  Next, in step S20, the display of favorites starts, but in this example, the display process of the group screen is performed. Definition data associated with the monitoring operation device 10 is acquired from each monitoring operation device according to the link source information. Note that the own node HMI1 may read its own definition data. Requests are made to the monitoring operation devices HMI2 and HMI3 connected by communication (S21, S23), and responses are received (S22, S24).

  Then, the comparison means program compares and collates the definition data associated with the read monitoring operation device with the type stamp, one by one for the ID of the operator dedicated database. As a result, if the definition data has a new type stamp, a warning is displayed (S30). This is the execution of the data comparison means. If there is no problem here, it is possible to shift to a normal group screen display. Alternatively, the group screen display may be executed ignoring the warning.

  Finally, as shown in FIG. 1, the step of uploading the operator dedicated database from the monitoring operation device 10-3 (HMI3) is indicated by S40 of HMI3. Due to an update operation of an operator performed in this device, the operator dedicated database (favorite) is updated and stored in the server by upload transmission (S41) from this monitoring operation device. This is the execution of the upload means.

  In this example, for the sake of explanation, it has been described that the definition database of the monitoring operation device 10 exists in each monitoring operation device. However, it is not always necessary to be concerned with this example, and they are also placed in the server 1. Alternatively, the definition database associated with the monitoring operation device of the present invention may be appropriately read from the server.
