Ecological Systems and Devices Annotation << Back About one Expert System for Operative Control of Water Bodies Mkrtchyan F.A., Soldatov V.Yu., Mkrtchyan M.A. The article presents the structure and functionality of an expert system for operational monitoring of water quality in a zone of anthropogenic infl uence. The implementation of the system is possible using both stationary and mobile measuring devices. The system is equipped with algorithms for identifying water pollutants based on measurements of their spectral images. Multichannel measurement data in the optical range of the electromagnetic spectrum is used as input information. An algorithm for learning and recognizing spectral images of water objects is described. This work presents a new approach to diagnosing the quality of water resources using spectral optical instruments in the form of a spectrophotometer and a spectroellipsometer. The proposed structure of the expert system can serve as the basis for organizing the corresponding environmental service.
