Description

APPLICANT:

ANDREW KILLICK Form COMMONWEALTH OF AUSTRALIA The Patents Act 1990 PETTY PATENT SPECIFICATION FOR AN INVENTION ENTITLED: MAPPING SYSTEM AND METHOD The following statement is a full description of this invention, including the best method of performing it known to me/us: -1- 2 "MAPPING SYSTEM AND METHOD" Technical field This invention relates to a mapping system and method.

The invention has particular but not exclusive application to systems and methods for mapping electrical circuits.

The invention has most particular application for mapping, and providing information in relation to, electrical circuits in buildings.

Background of Invention It is known that maps of electrical circuits, such as wiring diagrams, are provided in the switchboard or circuit board boxes in buildings and the like.

Such maps or wiring diagrams are usually hand drawn on sheets of paper which are stored in the box, or in some instances the sheets of paper are glued to the face of the switchboard.

When changes are made to the electrical circuits, such as by the addition of new circuits, new equipment, or new power outlets, the trades person making the changes is required (sometimes by regulation, otherwise in accordance with best practice) to mark the changes on the circuit map.

Often this is not done, and in other instances the maps go missing or with time become difficult to read.

Summary of Invention The present invention aims to provide an alternative to known methods and systems for mapping electrical circuits in buildings and the like.

As used herein the expression "buildings or the like" is to be given a broad meaning. The expression covers residential, commercial and industrial buildings in the normal sense of the word and also includes vehichles such as ships, aircraft etc, or other spaces where wiring diagrams etc as may be used.

This invention in one aspect resides broadly in a method of mapping electrical circuits in a building or the like, the method including:entering in a mapping data base circuit data representative of the electrical circuits, the circuit data being adapted to provide graphic information regarding the circuits; providing interrogation means at at least one control location in the building, the interrogation means communicating with the mapping data base; interrogating the mapping data base by the interrogation means to access the graphic information, and modifying the mapping data base in accordance with changes to the electrical circuits, whereby the mapping data base contains current up-to-date circuit information for graphic display.

In another aspect this invention resides broadly in a system for mapping electrical circuits in a building or the like, said system including:mapping data base means for storing circuit data representative of the electrical circuits, said circuit data being adapted to provide graphic information regarding the circuits; an electrical switch board associated with a respective electrical circuit; interrogation means for interrogating the mapping data base; input means for modifying said mapping data base in accordance with changes to the electrical circuits; graphic display means for displaying said graphic information, and data communication means for providing data communication between the electrical switchboard associated with a respective electrical circuit and the mapping data base; wherein the interrogation means, the input means and the graphic display means are associated with the data communication means.

In one embodiment the interrogation means, the input means and the graphic display means are included in a hand-held module and the switchboard is associated with connector means for establishing data communication between the data communication means and the hand-held module.

Alternatively the interrogation means, the input means and the graphic display means are included in the switchboard.

It is also preferred that the system includes data communication means providing data communication between a plurality of the switchboards and locations exterior to the building, whereby current up-to-date circuit information is accessible from the exterior locations.

Description of Drawings In order that this invention may be more easily understood and put into practical effect, reference will now be made to the accompanying drawings which illustrate a preferred embodiment of the invention, wherein:- FIG 1 is a schematic block diagram of the invention; FIG 2 is a schematic block diagram of the invention illustrating the provision of a hand held portable device for plugging in to the switchboard; FIG 3 is a schematic block diagram of the invention illustrating its use in an extended network; FIG 4 illustrates the topography for stand alone utilisation of the invention; FIG 5 illustrates the topography for local access utilisation of the invention; FIG 6 illustrates the topography for remote access utilisation of the invention, and FIG 7 illustrates the topographyfor full system utilisation of the invention.

Description of Preferred Embodiment of Invention FIG 1 illustrates a system 10 for mapping electrical circuits 12a, 12b 12n in a building 13 or the like (or a zone within a building such as floor or a discrete area rented to a tenant). System 10 has mapping data base means 11 for storing circuit data representative of electrical circuits 12a, 12b 12n. The circuit data is adapted to provide graphic information regarding the circuits.

Interrogation means 14 is provided at at least one control location in the building, in the pi'eferred embodiment seen in FIG 1 at switchboard 17, and communicate with mapping data base 11. Input means 15 is also provided at at least one control location in the building, in the preferred embodiment seen in FIG 1 again at switchboard 17, and enable mapping data base 11 to be modified by interrogation means 14 in accordance with changes to electrical circuits 12a, 12b 12n. Graphic display means 16 is also provided at at least one control location in the building, in the preferred embodiment seen in FIG 1 again at switchboard 17, and display the graphic information.

The operatrion is controlled by a data process controller 18 in known manner.

Alternatively as seen schematically in FIG 2, in a system 30 for mapping electrical circuits 12a, 12b 12n in a building 13 or the like, and having mapping data base means 11 for storing circuit data representative of the electrical circuits, interrogation means 19, input means 20 and graphic display means 21 are housed in a portable hand held access device 23 for plugging into switchboard 17 to access mapping data base 11 under the control of respective data process controllers 18 and 22.

FIG 3 illustrates an extended system 40 in which individual sub-systems within zones 24a, 24b 24n of building 25 communicate by communication link 26 with a centralised controller 27. Other zones 28n and other buildings 29n also communicate with centralised controller 27 by means of communication link 27.

The respective topographies for a stand alone system, a local access system, a remote access system and a full system are illustrated in FIGS 4 to 7 which are annotated for ease of reference.

Details of certain of the componentry illustrated in FIGS 4 to 7 now follow.

The display screens are LCD back lit with a 5 button keypad (Up, Down, Left, Right, Enter) providing programming access to the unit. The communications ribbon provides back entry access and the back plate contains a wiring harness and IC pin connection to a removable front panel.

The Communications Ribbon supplies power to the display screen and provides communications to and from the control unit. Insulation is 415 Vac rated for provision to install in switchboards.
