An early warning system for aquatic environment state monitoring based on an analysis of mussel valve movements

An early warning system for biological monitoring of aquatic environment is proposed, which is based on an analysis of mussel valve movements. It consists of an analog monitor of an original design (analog recorder and analyzer of opening/closing of valves in a group of mussels) and outside devices (multimeters, computers, and mobile phones). In the monitor, an analysis of the state of valve position sensors, summing/averaging of voltage values, and generation of a warning signal are performed in the analog mode. The proposed system (a) diagnoses the state of valve position sensors, (b) determines the voltage representing the average valve opening in a group of mussels (6–12 individuals), (c) generates a warning signal; and, by means of peripheral devices, (d) registers the average voltage of sensors and (e) transmits a warning signal via a mobile communication net. The system can provide an addition (and, sometimes, an alternative) to complicated digital systems analogous to MosselMonitor®.
