Title: (EN) ANALOG SPECTRUM DISPLAY FOR ENVIRONMENTAL CONTROL
Abstract:
(EN) A COMPUTER IMPLEMENTED ENVIRONMENTAL PROCESS CONTROL APPARATUS FOR DISPLAYING THE CONDITION OF SELECTED ATTRIBUTES OF N 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 N PLURALITY OF FIRST INSTANCES OF A DATA STRUCTURE AND N 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 FUTURE DATA PROCESSING MODULE, A GRAPHIC ENGINE, AND A DATA ACCESS LOGIC DEVICE. THE HISTORICAL AND FUTURE DATA PROCESSING MODULES RECEIVE AND COMMUNICATE HISTORICAL AND FUTURE DATA, RESPECTIVELY, TO THE FIRST AND SECOND INSTANCES OF THE DATA STRUCTURE. THE DATA ENTIRES 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. ANOTHER EMBODIMENT OF THE COMPUTER IMPLEMENTED ENVIRONMENTAL PROCESS CONTROL APPARATUS IS ADAPTED TO DISPLAY THE MAGNITUDE OF THE DEPARTURE OF A MEASURED VALUE FROM A SET POINT AND, OPTIONALLY, A RATE OF CHANGE OF THE DEPARTURE VALUE AND/OR A SECOND MEASURED VALUE FOR EACH OR SEVERAL OF THE PLURALITY OF ZONES OR COMPONENTS WITHIN THE FACILITY. IN THIS EMBODIMENT, THE CONTROL APPARATUS INCLUDES A MEMORY FOR STORING AT LEAST A FIRST DATA ENTRY HAVING A MEASURED VALUE FOR EACH OF THE PLURALITY OF ZONES WITHIN THE FACILITY, MEANS FOR ESTABLISHING A CONDITION SET POINT WITHIN EACH ZONE, A DATA PROCESSING MODULE FOR RECEIVING AND COMMUNICATING THE MEASURED VALUES TO THE FIRST DATA STRUCTURE, A GRAPHIC ENGINE, AND A DATA ACCESS LOGIC DEVICE. THE DATA ACCESS LOGIC DEVICE IS CONFIGURED TO RETRIEVE THE ONE OR SELECTED FIRST DATA ENTRY FROM THE FIRST DATA STRUCTURE, ACCESS THE APPRORIATE CONDITION SET POINT, CALCULATE A DEPARTURE VALUE FOR SELECTED ONES OF THE PLURALITY OF ZONES, AND COMMUNICATION THE DEPARTURE VALUES TO THE GRAPHIC ENGINE SUCH THAT THE GRAPHIC ENGINE CREATES A FIRST AXIS AND A PLURALITY OF SEGMENTS NORMALIZED TO AND EXTENDING FROM THE FIRST AXES SO AS TO INDICATE THE DEPARTURE VALUE FOR EACH OF THE SELECTED ZONES.
