1 is a system configuration diagram for a mobile-based real-time intelligent P&ID search method according to the present invention. As shown in the figure, the system according to the present invention is interlocked with a user mobile terminal 1, a WAS (Web Application Server) server 2 interlocked with the user mobile terminal 1, and a WAS server 2 It is composed of an EDMS (Electronic Document Management System) server (3). The user mobile terminal 1 interworks with the WAS server 2 through a network, and the user mobile terminal 1 may request the WAS server 2 to activate the web service application. When the WAS server 2 receives an application activation request from the user mobile terminal 1 , the WAS server 2 drives the application in the mobile terminal 1 . The EDMS server 3 stores various drawings, and converts them into PDF files according to the request of the WAS server 2 and sends them to the mobile terminal 1 .

2 is a flowchart of a mobile-based real-time intelligent P&ID search method for efficient plant operation management according to the present invention. As shown in the figure, the intelligent P&ID search method includes the steps of (a) a user requesting a web service application from the WAS server to the mobile terminal (S1); (b) activating, by the WAS server receiving the request, the web service application in the mobile terminal (S2); (c) inputting a tag desired by the user in the user's web service application (S3); (d) the web service application calling the P&ID drawing of the tag input by the user from the EDMS server (S4); (e) converting the P&ID drawing called from the EDMS server into a PDF file in the web service application (S5); (f) extracting text from the PDF file by the web service application (S6); (g) retrieving a tag input by a user from the extracted text and the location coordinates of the tag (S7); (h) inserting a hyperlink into a tag whose location coordinates are found (S8); and (i) storing the VECTOR PDF file in which the hyperlink is inserted into the tag as a new file name (S9).

First, the user goes through a step (S1) of requesting a web service application from the WAS server (2) to the mobile terminal (1). Since the user needs to drive the web service application with the mobile terminal 1 , the user first requests the web service application from the WAS server 2 . When the user clicks or touches the icon of the mobile terminal 1 , the web service application is requested to the WAS server 2 .

Next, the WAS server (2) receiving the request goes through a step (S2) of activating the web service application in the mobile terminal (1). The WAS server 2 activates a web service application in the user mobile terminal 1 and provides a U/I through which the user can input a tag to be searched using the mobile terminal.

Next, a step (S3) of inputting a desired tag by the user in the user's web service application is performed. The user inputs a tag using the U/I provided by the web service application. The tag includes a line number for a process or utility pipeline to which water or steam is supplied, an instrument number for various instrument devices mounted on the pipeline, various device numbers to which the pipeline is connected, and a pipeline It may be any one of various special items installed on it. Instrumentation devices may include temperature, pressure and speed sensors and the like. In addition, the devices include various devices such as a drum, a vessel, a tower, and a pump. The special item may include a control valve, a strainer, a safety valve, and the like.

Next, the web service application goes through a step (S4) of calling the P&ID drawing of the tag input by the user from the EDMS server (3). The web service application requests a P&ID drawing from the EDMS server 3 according to the user's request, and the received EDMS server 3 sends the stored P&ID drawing to the user's mobile web service application.

Next, a step (S5) of converting the P&ID drawing called from the EDMS server 3 into a PDF file in the web service application is performed. E, the server 3 sends the P&ID drawing for the called tag to the web service application, and the web service application converts it into a PDF file, or receives the converted drawing from the EDMS server 3 as a PDF file.

Next, the web service application goes through a step (S6) of extracting text from the PDF file. In order for the web service application to turn a PDF file into a VECTOR PDF file, it first undergoes a text extraction step.

Next, a step (S7) of searching for the tag input by the user and the location coordinates of the tag from the extracted text is performed. The web service application finds the tag input by the user in the extracted text, and retrieves the location coordinates of the tag. In order to insert a hyperlink by knowing the position coordinates of the tag on the drawing, the position coordinates of the tag are searched.

Next, a step (S8) of inserting a hyperlink into the tag whose location coordinates are searched is performed. This is to connect the tag with a hyperlink and add a function according to the user-defined tag. By inserting a hyperlink into the tag, when the user touches the tag using the mobile terminal 1, various information such as attributes of the tag can be read. A watermark or an image may be included along with the hyperlink. This is for security. This is for security for document forgery, such as changing tags included in hyperlinks to third-party hacking.

Next, a step (S9) of saving the VECTOR PDF file in which the hyperlink is inserted in the tag with a new file name is performed. Save the VECTOR PDF file with the hyperlink inserted as a new file name. Since the EDMS server 3 has original drawings such as CAD drawings or 3D drawings, the drawings received from the EDMS server 3 are converted into PDF files and exist. Therefore, it can be saved as a separate file name and saved with a new file name so that the user can later check the field with the user mobile terminal 1 .

The drawings that were first stored in the EDMS server 3 through the above steps are saved as VECTOR PDF files. The stored VECTOR PDF file is stored in the user's mobile terminal 1, and the user can utilize the stored file for field work or field check.

3 shows a result converted into a VECTOR PDF file. A hyperlink can be inserted into the tag through the same operation for each tag, and the VECTOR PDF file with the hyperlink inserted can be displayed as a final product.

The user can view the converted VECTOR PDF file in the PDF Viewer according to the user's request using a mobile terminal. 4 shows a step of recognizing a tag by executing the PDV Viewer. The step of recognizing the tag, (j) the web service application running the PDF Viewer on the mobile terminal (S10); (k) the step of rendering the VECTOR PDF with hyperlinks inserted into tags in the PDF Viewer as HTML (S11); and (l) adding a user-defined function by accessing the DOM after the tag is rendered in HTML (S12).

First, the web service application goes through a step (S10) of executing the PDF Viewer on the mobile terminal. The user executes the PDF Viewer on the mobile terminal 1 through the web service application.

Next, when the PDF Viewer is executed, the VECTOR PDF with hyperlinks inserted into tags in the PDF Viewer is rendered in HTML (HyperText Markup Language).

Next, after the tags are rendered in HTML, user-defined functions are added by accessing the DOM (Document Object Model). DOM stands for document object model, and refers to a format for expressing structured documents as an object-oriented model. The DOM provides a structured representation of the document's document, and provides a way for programming languages to access the DOM structure. As a result, it can help you access the DOM and change the document structure, style, or content. So you can access the DOM and add your own custom functions.

When the above operation is completed, the user can execute the PDF Viewer using the user mobile terminal 1 and touch the corresponding tag in the PDF Viewer. When a corresponding tag is touched, a screen is displayed on the mobile terminal 1 as shown in FIG. 5 , and a function 11 defined by the user and an item 12 displayed according to the function are displayed. Accordingly, the user can search for information on matters related to the corresponding tag through the user's mobile terminal 1 . As shown in Figure 5, the user-defined function for the tag CMMS (Computerized Maintenance Management System) information, EDMS information, streaming chart (Streaming Chart), engineer information (Engineer Information), comments (Comment) and properties (Properties) By touching , it is possible to inquire the linkage information while popover to the mobile terminal. 5 shows information on properties. CMMS information relates to a computerized maintenance system, and operation facility information for the corresponding tag can be inquired. EDMS information can be inquired about related drawings such as 3D modeling related to the tag. The streaming chart is to inquire a real-time chart for the value of the tag's temperature, pressure, or flow rate, etc., the engineer information is to inquire information about the engineer in charge of the tag, and the annotation is a comment on the field situation for the tag You can view the uploaded information by taking a photo and the like. For the attribute, attributes of the corresponding tag, for example, in the case of a pipe, information related to a diameter, insulation, information related to heat tracing, information related to a type of fluid flowing through the pipe, etc. may be inquired.

As described above, the intelligent P&ID search method according to the present invention enables the user to take an urgent response according to the on-site situation in the field using a mobile terminal, and actively handles problems occurring in the field, as well as in the field.
