Abstract
A computer implemented environmental process control apparatus for displaying the condition of selected attributes of a plurality of environmental control components or zones within a facility. One embodiment of the apparatus is configured to create a river of time display including a rivulet having an historical and future data segment corresponding to each of the plurality of components or zones. In order to create the river of time, the apparatus includes a memory having a plurality of first instances of a data structure and a plurality of second instances of a data structure for storing historical and future data, respectively, means for establishing a look back value, means for establishing a look forward value, an historical data processing module, a future data processing module, a graphic engine, and a data access logic device. The historical and future data processing modules receive and commnunicate historical and future data, respectively, to the first and second instances of the data structure. The data entries are then selectively retrieved by the data access logic device and communicated to the graphic engine such that the graphic engine creates the river of time display over a time interval that the data access logic device calculates based upon the look back and look forward values.

10. A computer implemented environmental process control apparatus for displaying the condition of selected attributes of a plurality of N environmental control components, the environment having a plurality of zones each with a control component communicating therewith, each control component being adapted to transmit an attribute condition indicating signal to said control apparatus, said control apparatus comprising:
-
a memory including; a data structure for storing a plurality of data entries for each of said plurality of N components, said data entries including an attribute condition, start, and end; a plurality of N first instances of said data structure for storing historical data for each of said plurality of N components, where N is a positive integer; and a plurality of N second instances of said data structure for storing future data for each of said plurality of N components; a time of day clock; means for establishing a look back value; means for establishing a look forward value; an historical data processing module with a field input adapted to receive an attribute condition indicating signal from each of said plurality of N components, said historical data processing module coupled to said first instance of said data structure to communicate said historical data thereto; a future data processing module adapted to receive user input corresponding to the desired attribute condition of said plurality of N components, said future data processing module coupled to said second instance of said data structure to communicate said future data thereto; a graphic engine that creates a first window and a time of day axis within said first window; and a data access logic device that accesses historical data from said plurality of N first instances of said data structure and future data from said plurality of N second instances of said data structure and communicates said historical and future data to said graphic engine such that said graphic engine creates a plurality of rivulets normalized to said time of day axis, each of said plurality of rivulets including an historical data segment extending from said time of day axis in a first direction and a future data segment extending from said time of day axis in a second direction opposite said first direction, said data access logic device configured to access a time of day from said time of day clock, access said look back value, calculate a look back start time by subtracting said look back value from said time of day, access said look forward value, and calculate a look forward end time by adding said look forward value to said time of day, said data access logic device configured to access said plurality of N first instances of said data structure and communicate each of said data entries therein having at least one of said start and said end between said look back start time and said time of day to said graphic engine such that said graphic engine creates said plurality of historical data segments, and said data access logic device configured to access said plurality of N second instances of said data structure and communicate each of said data entries therein having at least one of a start and end between said time of day and said look forward end time to said graphic engine such that said graphic engine creates said plurality of future data segments. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
