RAINWATER DRAINING SUPPORT SYSTEM, RAINWATER DRAINING SUPPORT METHOD, RAINWATER DRAINING CONTROL SYSTEM, AND RAINWATER DRAINING CONTROL METHOD

摘要

AN OBJECT OF THE PRESENT INVENTION IS TO PROVIDE: A RAINWATER DRAINING SUPPORT SYSTEM AND A RAINWATER DRAINING SUPPORT METHOD THAT ARE CAPABLE OF REDUCING THE NUMBER OF VARIABLES TO BE INPUT TO AN INFLOW-VOLUME PREDICTING MODEL OF AN INFLOW-VOLUME PREDICTING UNIT (42), AND FACILITATING A PREDICTION OF AN INFLOW VOLUME OF RAINWATER BY THE INFLOWVOLUME PREDICTING UNIT (42); A RAINWATER DRAINING SUPPORT SYSTEM AND A RAINWATER DRAINING SUPPORT METHOD THAT ARE CAPABLE OF PREDICTING A QUALITY OF INFLUENT WATER WHEN IT RAINS IN AN EASY AND ACCURATE MANNER; AND A RAINWATER DRAINING CONTROL SYSTEM AND A RAINWATER DRAINING CONTROL METHOD THAT ARE CAPABLE OF STABLY OPERATING A DRAINING SYSTEM. A RAINWATER DRAINING SUPPORT SYSTEM INCLUDES A RAINFALL VOLUME MEASURING UNIT (10) FOR MEASURING RAINFALL VOLUMES OF A PLURALITY OF AREAS, AND A LINEAR MAPPING UNIT (41) FOR CARRYING OUT A LINEAR MAPPING PROCESS FOR THE MEASURED RAINFALL VOLUME TIME-SERIES DATA MATRIX. THE LINEAR MAPPING UNIT (41) CARRIES OUT A LINEAR MAPPING PROCESS TO CONVERT MANY VARIABLE DATA OF THE RAINFALL VOLUME TIME-SERIES DATA MATRIX INTO LESSER VARIABLE DATA TO OBTAIN A LINEAR MAPPING DATA MATRIX. AN INFLOW-VOLUME PREDICTING UNIT (42) PREDICTS AN INFLOW VOLUME OF RAINWATER BY USING AN INFLOW-VOLUME PREDICTING MODEL TO WHICH THE LINEAR MAPPING DATA MATRIX OBTAINED BY THE LINEAR MAPPING UNIT (41) IS INPUT. ANOTHER RAINWATER DRAINING SUPPORT SYSTEM PREDICTS A FUTURE WATER QUALITY OF INFLUENT WATER, BY A SYSTEM IDENTIFICATION METHOD USING A NONLINEAR HAMMERSTEIN MODEL, BASED ON THE PRESENT WATER QUALITY, SOME PAST WATER QUALITIES, SOME RAINFALL VOLUMES OF THE PAST AND AN EXPONENTIAL IN SOME RAINFALL VOLUMES OF THE PAST, PROVIDED BY THE DATA OBTAINING AND MEMORIZING MEANS (52, 53). A RAINWATER DRAINING CONTROL SYSTEM INCLUDES A DETECTING MEANS FOR DETECTING A WATER LEVEL IN A PREDETERMINED UPSTREAM POINT, IN WHICH WATER FLOW TO THE PUMP PLANT, AND A MODIFYING MEANS (63) FOR MODIFYING AT LEAST ONE OF A PREDETERMINED STARTING WATER LEVEL (27A) AND A PREDETERMINED STOPPING WATER LEVEL OF THE RAINWATER PUMPS (35) BASED ON A FLOWING CONDITION.
