Title:
RULE-BASED CONTROL APPARATUS AND RULE-BASED CONTROL METHOD BASED ON DIAGNOSIS OF PROCESS STATE OF SEWAGE TREATMENT PLANT
Document Type and Number:
WIPO Patent Application WO/2013/125737
Kind Code:
A1
Abstract:
According to the present invention, a rule-based control apparatus based on a diagnosis of a process state of a sewage treatment plant is provided, the apparatus comprising: a data collecting unit for taking, as an input, inflow/outflow water quality data required for the diagnosis of the process state of the sewage treatment plant and process operation data, or taking, as an input, the historical data set stored in a database; a data pre-processing unit for removing the range of the numerical absolute value of the data input into the data collecting unit so as to pre-process the data; a data reduction unit for receiving the data pre-processed by the data pre-processing unit and reducing the pre-processed data so as to extract information on the process state from the historical data set of the sewage treatment plant by applying a multi-variable analysis technique to the pre-processed data; a process diagnosis unit for grouping the reduced data so as to derive a diagnosis result on the state of the current treatment performance from the reduced data, and deriving a discriminant function for discriminating the state of the grouped data so as to derive the diagnosis result on the discriminant function; and a control strategy call unit for calling the rule on the variation of the moderating variable of the process operation data by a simulation test preset for the group that indicates the diagnosis result derived by the process diagnosis unit.
