Here, the communication means between the monitoring control system 10 and the information sharing server 20 is not particularly limited, and may use the Internet or a dedicated line.

The information sharing server 20 has a function of a WWW (World Wide Web) server, and forms an intranet with a plurality of user terminals 31, 32, 33,... These user terminals 31, 32,
33 are specifically browser terminals such as personal computers provided with a WWW browser. It is assumed that a plurality of users have a preset access right to a display screen of information provided from the information sharing server 20.

Now, assuming that the monitoring control system 10 detects an accident of a monitored facility or an abnormality of a device and generates an alarm, the alarm is notified to the information sharing server 20. Here, the user terminal 31 having the access right is WW
When the information sharing server 20 is accessed via the W browser, the occurrence of an alarm is notified to the user terminal 31, and at the same time, an alarm display screen is displayed in a pop-up on the display of the user terminal 31.

FIG. 2A is a diagram showing an example of the alarm display screen 300. In the figure, reference numeral 301 denotes a list display of alarm contents, and the outline contents of the alarm (for example, occurrence of an instantaneous blackout in a certain area, occurrence of an accident in a distribution line, occurrence of a power failure, etc.) are displayed in a list format. ing. This list display 3
On the left side of 01, a confirmation display section 302 composed of a circular figure is provided for each alarm content, and a confirmation button 303 is provided below them. A certain alarm content is designated by a cursor or the like. When the user clicks the confirmation button 303 after confirming, the color of the confirmation display portion 302 on the left side of the alarm content becomes white, and the unconfirmed alarm content that is not outlined and the confirmed alarm content are displayed. It is identifiable. The confirmation display section 302 and the confirmation button 303 constitute a confirmation input / display section in the claims.

FIG. 2B shows a menu screen 304 constantly displayed on the display of the user terminal 31.
When a system accident (distribution line accident), power outage, or instantaneous power outage occurs, a detailed description of the content of the alarm (the specific situation of the alarm occurrence and how to deal with it) is displayed on a separate screen. Button 305 is colored appropriately (for example, red)
To display a flicker, and call the user to refer to the detailed description. When the user clicks the detailed explanation button 305, an alarm detailed explanation screen as shown in FIG. 3 is displayed. Above detailed explanation button 30

The display format and display contents can be arbitrarily set and changed.

In the present embodiment, after the user confirms the contents of the alarm, a screen display as shown in FIGS. 2 and 3 is displayed in the next step to confirm the specific situation of the alarm occurrence and the coping method. By doing so, it is possible to eliminate the risk of proceeding to the next step without confirming the contents of the alarm, and to quickly grasp the specific situation and collect information for dealing with the situation.

Next, a description will be given of a means for updating the user management information associated with an organization change / transfer. First, as for the display screen of the information provided from the information sharing server 20, the access right of the user is set for each screen regarding the content and the importance. That is, since user management is performed so that only a specific user registered in advance on each display screen can be accessed, it is necessary to update user management information due to organization change, transfer, or the like.

FIG. 4 is a diagram showing a conventional user management information update screen (access right setting screen). Conventionally, when updating the user management information, an access right setting screen 400 as shown in FIG. 4 is called. When a target screen for which an access right is to be set and a user's target department are selected from the pop-up menu on this screen 400, a list 401 of the target screen and the access-permitted users in the target department is displayed. The list 401 is provided with a name field and a check box of “reference” or “update”, and “reference” which is an access right for simply browsing the target screen, and information displayed on the target screen. (Update information), which is an access right for correcting or approving a part of the information (e.g., coping information other than online / real-time information, report contents, etc.). Note that “update” is a wider access right including “reference”.

For example, if the personnel of the department concerned is changed due to a personnel change and it becomes necessary to update the user management information, the operator changes the user name in the list 401, and takes into account his / her job system and the like. The user management information (and its access right) is updated by clicking the check box of “reference” or “update”. Traditionally,
As described above, it is necessary to update the access right for each user for each screen and for each department, and the operation is extremely complicated.

On the other hand, in the present embodiment, as shown in FIG. 5, a screen management table 500 and a user management table 600 are created in advance, and these tables 500,
Access control table 7 by linking information in 600
Create 00. Explaining the information serving as the contents of these tables, the screen management table 500 defines a screen group number, a screen type, and a screen rank for each screen. As shown in FIG. (For example, XX monitoring screen for monitoring screen, △△
Monitoring information, etc.), work support, operation plan,..., Is type information on screen functions and properties, and the screen rank indicates the importance of the screen (important confidentiality, handling caution, confidential, etc.) by A, B, C. , ……. In addition,
For the screen group No., for example, if the screen type is the monitoring screen (XX
, And are assigned a predetermined number 1, 2, 3,... Respectively.

The user management table 600 defines user type information such as a department number, a job system number, and an engaged job number under a user group number. For example, the department number is shown in FIG. No. 1, 2, 3
3, ... are assigned. In addition, user group
The NO. Is a predetermined number 1, 2, 3, or 3 for each content of the user type information including, for example, a department NO., A job system NO.
…… is assigned.

In setting an access right, an access management table 700 including a screen group No., a user group No. and an access right is created as shown in FIG. 5 using the information of the tables 500 and 600. This table 700 is used to grant reference or update access rights to one or more screens specified by the screen group No. for one or more users specified by the user group No. The access right is reflected (overwritten) by the content (reference or update) input from the access right setting screen 800 described later. As described above, by specifying the above-described screen group No., it is specified which screen type and which screen rank have the access right setting target, and the user group No.
By designating, the user having the user type information to which the access right is to be granted is specified.

FIG. 7 shows an example of an access right setting screen 800 displayed based on the access management table 700. The target screen group (screen type) to which the access right is granted is a monitor screen, the screen rank is A, and the user is a user. Type is department:
Operation management, job system: none, work location: Tokyo, engaged duties: access rights are set for users corresponding to office work. These pieces of display information are acquired based on the contents of the access management table 700 as described above.
After confirming the screen group, screen rank, and user type, the operator inputs and sets “reference” or “update” as the access right. When the access right is set in this manner, the set contents are stored in the access management table 70.
0 and is stored in the database on the information sharing server 20 side.

Next, the process of updating the user management information will be described. Here, the update of the user management information is a concept including any of the user type information, for example, a new addition and a change (name change) of a department, and an access right is given to a new department or an access right is already granted. This refers to the process of changing the name of the department that owns it.

FIG. 8 is a flowchart showing a general flow of the user type updating process. First, it is determined whether a user type (for example, a department) is newly added or changed (S1). In the case of a new addition, the user type is added on a user type update screen 900 described later (S2). Next, the service of the screen corresponding to the new user type (for example, setting of access right such as reference, update, deletion, etc.) is set in the information sharing server 20 (S3), and the process ends. If the user type is changed, the user type data is rewritten on the user type update screen 900 (the name of the department is changed) (S4). Then, the access right (the access right of the user group) relating to the department before the rewriting is taken over as it is (S5), and the process ends. In other words, only the department name is changed, and the contents of the access right remain unchanged.

FIG. 9 is an explanatory diagram of the operation in the user type updating process, and mainly shows the user management table 600. In FIG. 9, the department is used as the user type information.
No .: 9, department name: The case where a material department is newly added, and the case where the conventional department No .: 1, department name: the name of the general affairs department is changed to the department name: general affairs / management department are illustrated. . in this case,
The contents of the screen group No., user group No., and access right in the access management table 700 are inherited as they are.

FIG. 10 shows an example of a user type update screen on the user terminal used for updating the user type. The information sharing server 2 is accessed from the user terminal using a WWW browser.
The user can access and call the homepage of No. 0. The user type update screen 900 can be reached by narrowing down the update targets by a pop-up menu, and includes a check box 901 and an input space 902 for each of a new addition and a change for the user type: department to be updated. The operator clicks and selects one of the check boxes 901 for new addition or change, and inputs and sets a predetermined department name in the input space 902.

When the setting is completed, the user management table 6
00 is updated and held in the information sharing server 20 side, and the link between the updated user management table 600 and the screen management table 500 forms an access management table 700 as shown in FIG. In this case, since the user group No. itself has not been changed, the access management table 700 has not been changed in form.
The internal information of the user group (contents of the user management table 600 including the department) inherited by the same NO. Has been changed, and the department within the user type on the access right setting screen 800 in FIG. Becomes Then, if the contents of the access right (reference or update) can be left unchanged, there is no need to set the access right again, and the access right may be set again only when necessary.

According to this embodiment, the screen management table and the user management table are linked to form the access management table, and the updated content of the user type information is reflected in the access management table via the user group No. Therefore, the update of the user type information and the setting of the access right can be performed collectively, and the work of updating the user management information with the access right can be performed in a short time and with a small effort.

[0032]

As described above, according to the present invention, the information such as the general contents of the alarm, the specific situation, the coping method, etc. can be reliably and promptly acquired on the WWW browser. This is extremely effective for the user to respond appropriately. Moreover, complicated work is not required when updating the user management information, so that a work error can be reduced and a work time can be reduced.
