Claims

1. In a design error prevention method through consistency check and design RULE check of 3D CAD model of engineering data for plant engineering using a design RULE data server, a vendor data server and a 3D CAD modeling data server,
(a) Checking whether to reflect the design RULE to 3D CAD model comprises: Registering a project name with the design RULE data server; Inputting a design RULE for the registered project by a category of categories including design and engineering sector, operation sector, maintenance sector and safety sector; Designating and storing a value in the input design RULE; Checking whether to violate the design RULE by applying the design RULE value to the 3D CAD model; and Outputting a result of the checked design RULE; and
(b) Checking engineering data consistency of the 3D CAD model comprises: Collecting and classifying vendor drawings submitted in the form of a file by an equipment manufacturer or an equipment supplier; Analyzing data by data mining techniques and extracting target data from the collected and classified vendor drawings; Searching 3D CAD modeling data matched with the extracted target data and mapping the searched 3D CAD modeling data and the extracted target data; Checking the consistency between the mapped 3D CAD modeling data and the extraction target data; and Reporting results of an inspection, changing the 3D CAD modeling data, or providing or transmitting the results to a user, when the consistency check is completed,
wherein the design RULE in the design and engineering sector category includes design compliance of wall and pipe space, pipe and pipe space, pipe and flange clearance, flange and flange clearance, check valve direction, steam pipe drip Leg, pump suction reducer type, vent location and size, drain location and size, flare header minimum slope, and orifice plate minimum meter-run,
wherein the design RULE in the operation sector category includes design compliance of valve stem orientation for fail safe valve operation and the BOP (Bottom of Plane) elevation of control valve manifold for safe operation of a valve, valve bottom and floor space, a gap between BOP of bypass and actuator of control valve, stairway headroom clearance, pedestrian access way, and thermal expansion,
wherein the design RULE in the maintenance sector category includes design compliance of pipe rack future space, heat exchanger maintenance volume, and
wherein the design RULE in the safety sector category includes design compliance of fired heater valve location and safety valve discharge design.
2. The method of claim 1,
Wherein the design RULE by category can be used as it is, added or deleted in a design RULE registered in the design RULE data server.
3. The method of claim 1,
Wherein designating and storing the design RULE value is designating and storing the design RULE value to a pipe routing type to which the design RULE is applied in the 3D CAD modeling data, or designating and storing the design RULE value to a predetermined routing type object according to type, direction and location of each piping component in the design RULE data server.
4. The method of claim 1,
Wherein designating and storing the design RULE value is designating and storing the design RULE value to a machine type to which the design RULE is applied in the 3D CAD modeling data, or designating and storing the design RULE value to a machine type which is matched with a predetermined machine type in the design RULE data server after it is recognized by characteristics of tag rules and nozzles which are components of each machine.
5. The method of claim 2,
Wherein designating and storing the design RULE value includes designating a type and a position value which vents, drains or pipe drip legs as piping components should exist, designating a distance or a span between one component and another adjacent component, designating engineering values to be observed for one component, designating position values of the components required for operation, designating a volume for a workspace and movement path for an operator's operation, or designating a volume required for maintenance.
6. The method of claim 1,
Wherein checking whether to violate the design RULE includes recognizing dimension, direction and spatial information of one component and dimension, direction and spatial information of another adjacent component from the 3D CAD modeling data and checking whether to violate by comparing the designated design RULE value with a value of a distance or a span between one component and another adjacent component.
7. The method of claim 1,
Wherein the vendor drawings are submitted by the form of a PDF file, and the information on the manufacturer and equipment type is collected and classified from the PDF file.
8. The method of claim 7,
Wherein analyzing and extracting data by a data mining technique includes extracting dimension and shape data of a two-dimensional drawing for equipment and various text information data of the drawing from vendor drawings collected and classified by manufacturer and equipment type; and filtering and extracting the extracted data into necessary target data by analyzing the extracted data.
9. The method of claim 8,
Wherein searching 3D CAD modeling data matched with the extracted target data includes searching 3D CAD modeling data that is matched using as keywords data for an area of the equipment and a name of the equipment, and mapping of the searched 3D CAD modeling data and the extracted data includes mapping elements that are targets for design between the searched 3D CAD modeling data and the extracted target data.
10. The method of claim 9,
Wherein the consistency check includes a dimensions for a height and width of the equipment, dimensions between components of the equipment, and design data of the equipment to be written at the vendor drawings.
11. The method of claim 10,
Wherein reporting the results of the inspection, changing the 3D CAD modeling data, or providing or transmitting the results to the user, when the consistency check is completed, includes generating a list of the inspection results for errors of the 3D CAD modeling data, displaying the list on a screen, changing the 3D CAD modeling data having errors according to converted data on the vendor drawings, and transmitting the list for the errors to the user.
