[0014]
[Description of Concept and Basic Configuration of the Present Invention]
FIG. 1 is a diagram for explaining the basic concept of a database information remote control system according to the present invention. In FIG. 1, a server 11 of an information provider 10 stores graphic information 12 and character information 13 in a database, and implements a function of an agent 14. The agent 14 has a function of autonomously interpreting a list-format command transmitted from the terminal 21 of the client 20, and editing and processing the graphic information 12 and the character information 13.
[0015]
The system shown in FIG. 1 processes and edits the graphic information 12 and the character information 13 in the following manner.
{Circle around (1)} On the client 20 side, the client terminal 21 selects a list (a list of instructions executable by the agent 14) for instructing graphic editing, screen control, database operation, etc., and creates a “list selection instruction”. It is transmitted to the agent 14 of the server 11.
{Circle around (2)} The agent 14 receives the “list selection command”, interprets the received list, and edits or processes the graphic information 12 and the character information 13.
[0016]
As described above, in the database information remote control system of the present invention, the graphic information 12 in the server 11 is transmitted by the list command transmitted from the client terminal 21 without transmitting the entity data from the server 11 to the client terminal 21. By editing and processing the character information 13, the following effects can be obtained as compared with the conventional example.
・ Simplification of interface
There is no need to create an interface for individually handling data of different formats such as graphic information and character information, and the interface can be simplified.

[0017]
FIG. 2 is a diagram for explaining the basic configuration and operation of the remote control system for database information according to the present invention, and more specifically shows the basic conceptual diagram shown in FIG. This is an example in which the used “command by list” is “command by script language” and the function of “agent” is realized by a “script command interpreter”.
[0018]
In FIG. 2, editing of a drawing or the like is performed as follows.
(1) Request for drawing reference / update
A “drawing reference / update request” for a drawing (vector information drawing) 32 such as a CAD drawing stored in the database 31 is transmitted from the Web browser on the client terminal 40 side to the server 30.
[0019]
(2) Send image creation data / script list
The “image creation information” and the “script list in object units for editing and processing graphics” are transmitted from the server 30 to the Web browser of the client terminal 40. The image 41 is displayed on the Web browser of the client terminal 40. Note that the “image creation information” transmitted from the server 30 to the client terminal 40 is not the entity data (vector information) of the drawing 32 but information of the raster image 41 which is merely an index for specifying an object.
[0020]
(3) Designation and confirmation of edit target
When a target figure (object) to be edited is specified on the Web browser screen, an executable script list 42 for each object is displayed. A desired script is selected from the script list, and editing and processing of drawings as described below are performed.
・ Figure editing (addition / deletion)
.Coordinate transformation / movement of figures
・ Database editing
・ File output / transmission
[0021]
(4) Select / Execute command transmission
The script selected from the script list 42 is transmitted from the client terminal 40 to the server 30, and an instruction is issued to execute the script.
[0022]
(5) Drawing editing by script execution, etc.
In the server 30, the contents of the script list received from the client terminal 40 are interpreted by the script command interpreter 33, and the selected script is executed to edit or process the drawing 32.
[0023]
(6) Transmission of script execution results
When the script is executed by the script command interpreter 33 in the server 30, the execution result is transmitted to the client terminal 40. The result report and information on the database control results (editing and processing results, etc.) are transmitted.
[0024]
As described above, without transmitting the entity data of the drawing 32 from the server 30 to the client terminal 40, the command based on the script selected on the client terminal 40 is received, and the drawing 32 in the database 31 is edited and processed. By performing the above, the following effects can be obtained as compared with the conventional example.
Reference and editing of drawings and databases can be performed without distributing entity data between the server 30 and the client terminal 40. Thus, there is no problem of leakage of the entity data.
・ Dynamic database editing and screen control using scripts.
-By mounting the script command interpreter 33 in the server 30, the control content can be easily and quickly changed by the script.
[0025]
The basic configuration and operation of the database information remote control system of the present invention have been described above. Next, a more specific example will be described.
[0026]
[Application example to facility management system]
An example in which the remote control system for database information according to the present invention is applied to a facility management system will be described.
1. INTRODUCTION
The facility ledger information is an aggregate of various individual information related to the facility, and is the most basic and important information indicating the status of the facility in the facility management. During full-scale introduction and operation of facility management, the facility ledger information is always kept up-to-date, and the information is processed according to the purpose, and reports and port ferrios (hereinafter also referred to simply as “reports, etc.”) ), It is necessary to realize an environment that allows reference.
In this example, in a facility ledger management system (facility management system) for sharing facility ledger information in a wide area in a network environment, an example of a system that realizes creation and reference of a report or the like with a high degree of freedom according to the purpose. It is shown. Of course, the editing and processing of the facility ledger information can be similarly performed.
[0027]
2. Sharing and utilizing facility ledger information in a network environment
The facility ledger information is composed of various information such as drawings, images, database information, etc., and the contents range from those that show the current status of land, buildings, facilities, etc., to inspection schedules, facility operation costs, construction history information, etc. Crossing. The use of facility ledger information in facility management is broadly divided into the maintenance and use of individual information, and the use of facility information by integrating and processing multiple pieces of information. In particular, reports and the like that utilize multiple pieces of information in making management decisions and comprehensive evaluations of facility management occupy an important position.
Further, the system of this example is a stand-alone facility ledger management system CAFM (Computer Aided Facility Management) type system from the viewpoint of sharing the facility ledger information between the ledger information providing side and the ledger information reference side in a network environment. This is an example of a system in which a plurality of users share and refer to the facility ledger information constructed and maintained in the network environment by using a Web function of a Web-type system. Further, in the system of this example, the provider side guarantees the quality of the facility ledger information, thereby realizing a ledger information reference method using a simple interface of the Web browser on the reference side.
Also, when creating and referring to a report or the like based on facility ledger information in a Web-type system, it is possible to define an individual creation logic in advance and execute this to refer to a target report or the like. It is. However, facility evaluation methods of facility management differ depending on the type of facility, operation mode, and target business area, and there is a limit in defining fixed logic individually. In addition, responsiveness to changes in evaluation methods and changes in forms such as reports is low.
Further, when creating a report or the like based on the simulation result, it may be necessary to change the facility ledger information. At this time, in a Web system using a basic user interface of the Web browser, it is possible to change the character / numerical information by using the function of the Web browser. However, as for the graphic information, a method of converting drawing data into clickable maps and image data and displaying the converted data on a Web browser is used, so that it is difficult to dynamically change, for example, replacing objects in the drawing. In order to solve these problems, it is necessary to combine the basic functions of the Web system in a versatile manner and realize an environment that is executed from the client side. Therefore, the system of the present example realizes a system using a script command interpreter that enables control of a server program using a simple language.
