Control system for controlling environmental conditions in a closed building or other conditions

Claim 1

An environmental control system for monitoring and controlling at least one measured physical parameter for maintaining environmental conditions in accordance with predetermined control parameter data, said environmental control system generating updated control parameter data for updating said predetermined control parameter data, said environmental control system comprising: (i) at least one climate sensing device responsive to said at least one measured physical parameter for generating signals indicative of said at least one measured physical parameter; (ii) at least one controlled climate device for adjusting said at least one measured physical parameter; (iii) at least one controller receiving said signals and converting said signals into measured parameter data, said at least one controller performing a comparison between said measured parameter data and said predetermined control parameter data for generating output signals controlling said at least one controlled climate device in response to said comparison for minimizing the difference between said measured parameter data and said predetermined control parameter data; (iv) separate information processing means capable of addressing said at least one controller for accessing said measured parameter data and said predetermined control parameter data from said at least one controller, said separate information processing means capable of generating said updated control parameter data for updating the predetermined control parameter data of said at least one controller specified by said separate information processing means; and (v) at least one data concentrator for collecting said measured parameter data and said predetermined control parameter data from said at least one controller, said at least one data concentrator responsive to requests generated by said separate information processing means for providing said information processing means with said collected measured and control parameter data, said at lest one data concentrator addressing said at least one controller for providing said at least one controller with updated control parameter data generated by said separate information processing means, said at least one data concentrator including: (i) data storage means for storing, said measured parameter data of said predetermined control parameter data received from said at least one controller and said updated control parameter data provided by said separate information processing means; and (ii) data processing means periodically polling said at least one controller for said measured parameter data and said predetermined control parameter data said data processing means placing said measured parameter data and said predetermined control parameter data into said data storage means, said data processing means directing said updated control parameter data to said at least one controller; (iii) first communication interface means associated with said data processing means for receiving said measured parameter data and said control parameter data from said at least one controller, said communication interface means transmitting said updated control parameter data to said at least one controller; (iv) second communication interface means associated with said data processing means for transmitting said measured parameter data and said control parameter data to said separate information processing means, said second communication interface means receiving said updated control parameter date from said separate information processing means.
