AUTONOMOUS, CONTINUOUS AND IN SITU MONITORING SYSTEM FOR THE QUALITY OF WATER

摘要

The device (31) detects pathogenic micro-organisms, having a biosensor with a receptor layer for receiving biological material and identification of the pathogenic micro-organisms by antibody-antigen reactions. The intermediate element is connected with the device by an electronic module. The chamber is in contact with the receptor layer of the detection device. The biosensor comprises a wave coil with a piezoelectric substrate, a delay line having an input/output electrode are placed on the surface of the substrate, and a guiding layer of dielectric material, which covers the substrate surface and the input/output electrodes, where the guiding layer eliminates the conductivity of the liquid medium. The acquisition module comprising a network of artificial neurons, an ensemble of programmable circuits, a micro controller, which is placed on a electronic board to process the data of the output frequencies of the oscillators, and a frequency counter for measuring the output frequencies of the oscillators. The elements are associated with a peristaltic pump for water circulation and valves to control the sequences of cleaning and detection of pathogenic microorganisms. An independent claim is also included for a real time detection device using the above system.
