Embodiment Construction

[0029] The description of the embodiments of the invention refers to the accompanying drawings, which illustrate specific embodiments in which the invention may be practiced.

[0030] See figure 1 . The sewage treatment control system provided by the present invention is a feedback control system. The ontology-based sewage decision-support system 100 sequentially performs the process of sewage knowledge acquisition, sewage ontology reasoning and sewage facility treatment by connecting to the external environment, and then passes the sensor. Sampling of sewage information after treatment by sewage facilities, and feeding back to sewage knowledge acquisition together with execution commands.

[0031] see figure 2 . Firstly, a sewage decision-support system 100 based on ontology in the present invention includes a data acquisition layer 10, a diagnosis layer 20, and a decision-support layer 30; the data acquisition layer 10 includes an online sensor 11, a laboratory 12 and a da...

Abstract

The invention provides an ontology-based sewage decision-support system and method. The system comprises a data collection layer, a diagnosis layer and a decision-support layer, wherein the data collection layer is used for obtaining online sensor data, offline measurement data and data subjected to calculation through an online sensor and a laboratory; the diagnosis layer is used for respectively processing and diagnosing data from the data collection layer by adopting a rule-based reasoning module and a case-based reasoning module, and diagnosing and processing the data from the data collection module by adopting a sewage body module if the two modules are incapable of obtaining a diagnosis result; and the decision-support module comprises a user interface and a monitor module, the monitor module is used for providing complete decision information and corresponding ontology types according to the diagnosis result from the diagnosis layer, the user interface is used by a user to activate a sewage treatment system for selecting a sewage treatment mode, and the user can inquire a specific reason of the sewage treatment mode by virtue of the user interface. According to the invention, the reliability of the sewage decision-support system is improved, sewage knowledge is reused and shared, and the transportability of the whole system is improved.

Description

technical field [0001] The invention relates to the technical field of sewage management, in particular to an ontology-based sewage decision-support system (ontoWEDSS) and method. Background technique [0002] Due to the characteristics of multi-variable, nonlinear, time-varying and randomness in the treatment process of sewage treatment system, it presents instability and uncertainty, and it is difficult to achieve ideal control effect by using conventional and simple models. The existing sewage treatment assumes that the sewage management system is in a stable state, without considering the complex factors of real sewage treatment, so this traditional control still has many limitations. [0003] In order to solve the above sewage management problems, domestic and foreign scholars have explored the application of expert systems in process evaluation, automatic control and fault diagnosis of sewage treatment systems. However, as the knowledge obtained in the process of sewa...
