Abstract

A system for creating as-built or measured drawings is described herein. The invention allows an operator to collect a set of data at a job-site, in such a manner that individual components of the job-site are linked relative to one another and to use that data to create accurate measured drawings that reflect the structure and content layout of the site. A knowledge based system is used to parse the data in real-time to produce a visual indication that the data has been recorded correctly. Error minimizing functions are used to ensure data integrity. The data may then be uploaded to a central computer server, for content-checking, authorization, and archival purposes. Since the invention provides an integrated environment for recording data and creating drawings, the need to translate data between systems is minimized, reducing the possibility of errors due to operator mis-keying or mis-interpretation.

Claims

1. A method for recording data for use in creating measured drawings of a building, site, or structure, comprising the steps of:

acquiring, either automatically by a portable data recording device or as user input into the portable data recording device, a sequence of data describing the components of a building, site, or structure, including any of the levels, spaces, or objects contained therein, wherein for a particular component the data describing the particular component includes at least a partial placement, orientation, or dimension information that relates the particular component to a previously acquired component in the sequence;

automatically determining a remaining placement, orientation or dimension information for the particular component; and

storing the data describing the components into the portable data recording device as a plurality of hierarchically linked data entries, so that the data can be subsequently retrieved and parsed to create a measured drawing of the building, site, or structure.

2. The method of claim 1 further comprising the steps of:

parsing the plurality of data entries, using a knowledge base, to create a set of parsed data describing the physical layout and dimensions of the building, site or structure components;

converting the parsed data to image render data duplicating the physical layout and dimensions of the levels, spaces, or objects; and

,

translating the set of rendered data into a drawing component syntax format suitable for use by a computer aided drawing application.

3. The method of claim 2 further comprising the steps of:

drawing the translated data for verification, editing and output as a completed measured drawing of the building, site, or structure.

4. The method of claim 3 further comprising the steps of:

exporting the measured drawing of the building and its components to a file or directly to another computer aided drawing application.

5. The method of claim 1 wherein the step of acquiring data includes using a knowledge base to intelligently infer data and mandate user input compliance.

6. The method of claim 1 wherein the step of receiving data includes determining for a first level, space, or object, a component type and a set of measured values associated with the physical attributes of the first level, space, or object.

7. The method of claim 6 wherein the component type is any of a level, area, room, wall, line, or object of the building, site or structure.

8. The method of claim 2 wherein the step of parsing comprises:

accessing a data entry in the database;

reading the component type of the level, space, object, or component defined by the data entry;

reading the measured values of the level, space, object, or component defined by the data entry;

reading the relationship of the first level, space, object, or component to a second level, space, object, or component; and

determining the physical attributes of the level, space, object, or component, and the relative spatial location of the level, space, object, or component with respect to a second level, space, object, or component.

9. The method of claim 8 wherein the step of determining includes referencing a knowledge base of components wherein the knowledge base includes an entry for the component type, and wherein the entry defines how the physical attributes of the level, space, object, or component are related to the measured values of each level, space, object, or component.

10. The method of claim 9 wherein the knowledge base includes drawing attributes of each level, space, object, or component that are used in creating a drawing containing the level, space, object, or component.

11. The method of claim 10 wherein the step of translating includes:

generating commands to a drawing program communicating the physical attributes of the level, space, object, or component, the relative spatial location of the level, space, object, or component, and the drawing attributes of the level, space, object, or component.

12. The method of claim 1, further comprising the steps of:

outputting a drawing of the building and its components.

13. The method of claim 12 wherein the drawing is a drawing of a level of the building.

14. The method of claim 13 wherein the step of receiving data includes the steps of:

determining a first level, space, object, or component of the building, including;

associating a component type with the first level, space, object, or component,

measuring a physical attribute of the first level, space, object, or component, and

determining a coordinate location of the first level, space, object, or component,

relative to a fixed origin; and

determining a second level, space, object, or component of the building, including;

associating a component type with the second level, space, object, or component,

measuring a physical attribute of the second level, space, object, or component, and

determining a coordinate location of the first level, space, object, or component, relative to the second level, space, object, or component.

15. The method of claim 14 wherein the step of outputting includes:

displaying the components on a graphical screen to represent the spatial location and dimensions of the components as collected in the data.

16. A system for creating measured drawings of a structure comprising:

a portable data recorder device that allows an operator to record information about the content and layout of objects in a building structure, the portable data recorder including;

a data interface that enables automatic acquiring of data or allows a user to enter a sequence of data describing the components of a building, site, or structure, including any of the levels, spaces, or objects contained therein, wherein for a particular component the data describing the particular component includes at least a partial placement, orientation, or dimension information that relates that component to a previously acquired component in the sequence;

a knowledge base that automatically determines a remaining placement, orientation or dimension information for the particular component; and

a data storage that stores the data describing the components as a plurality of hierarchically linked data entries, so that the data entries can be subsequently retrieved and parsed to create measured drawings.

17. The system of claim 16 further comprising:

a login interface to authorize a user to access the system.

18. The system of claim 16 wherein the input interface includes a touch-sensitive pad.

19. The system of claim 16 wherein the input interface may be used to connect an automatic measuring device to the recording device for the communication of measurement data.

20. The system of claim 19 wherein the automatic measuring device is a laser plane device with distance measurement logic.
