A Study on the System Design of Buoy-Type Automatic Water Quality Monitoring Equipment Based on KJ-AHP

Water resources are vital to human society and natural ecosystems, and water quality monitoring, as an important means of detecting and evaluating water resources, is able to understand the pollution of water bodies in a timely manner and make predictions, which provides an important scientific basis for the protection of water resources and the maintenance of ecosystems. This paper explores the application of the KJ-AHP method in the design of buoy-based water quality monitoring equipment. Firstly, the KJ method (Affinity Diagram Method) is used to sort out the product requirements of water quality monitoring equipment in market products and literature materials; the weights of the indicators are calculated through user interviews, questionnaires and the Delphi method, and one target layer, four first-level indicators, and twelve second-level indicators are screened out; then another round of expert questionnaires is carried out, and the performance demand hierarchical model of the buoy water quality monitoring equipment is constructed and the consistency test is completed; the conclusions of the study are applied to the design of a new buoy water quality monitoring equipment, and the design of a new buoy water quality monitoring equipment is developed.
