Communications network for identifying the location of articles relative to a floor plan

A method for identifying the location of articles relative to a known floor plan, said method comprising the steps of:

• positioning a plurality of communication modules at known locations relative to the floor plan;
• providing each communication module with a unique identify;
• connecting each of the communication modules to a controller;
• providing each communication module with a coupler for connecting an article to the controller;
• storing a layout of the floor plan that is accessible to the controller and that includes the location of the communication modules relative to the floor plan;
• and
• determining the location of an article relative to the layout of the floor plan by determining to which of said communication modules the article is connected.

A system for identifying the location of utility appliances relative to a known floor plan, said system comprising:

• a controller;
• and
• a plurality of communication modules positioned at known locations relative to the floor plan, each of said communication modules being in electrical communication with said controller and having an identification device therein for identifying itself to said controller, said communication modules including a coupler for connecting at least one utility appliance to communicate with said controller,
• wherein said controller includes a memory for storing a layout of the floor plan based upon the known location of said communication modules, and said controller determines the location of a utility appliance relative to the layout of the floor plan by determining to which of said communication modules the utility appliance is connected.
