摘要： The aquatic installation predictive maintenance system (100) comprises:
at least one physical/chemical sensor (110, 115, 116, 117, 181, 182, 183, 184) interacting with water in at least one aquatic installation and configured to provide series of at least one sensed value representative of a physical/chemical parameter, and
at least one processor (120) configured to execute instructions representative of the steps of:
operating a trained machine learning model, said model being trained to associate, for at least one series of sensed value representative of a physical/chemical parameter, at least one aquatic installation operational degradation event associated with a date of event occurrence, and
determining a sequence of maintenance operations to be performed on at least one aquatic installation as a function of at least one predicted aquatic installation operational degradation event and associated date of event occurrence.-

摘要： The aquatic installation four-dimensional monitoring system (100) comprises:
a submersible and/or floating vehicle (105, 106), comprising:
a relative positioning coordinates acquisition means (110), configured to locate, in a three-dimensional space representative of the aquatic installation (111), the submersible vehicle and to provide the corresponding coordinates of the submersible and/or floating vehicle, and
a water physical and/or chemical sensor (115), configured to provide a measure of a local physical and/or chemical state of the aquatic installation in the proximity of the submersible and/or floating vehicle, and
a timestamping means (120), configured to associate, with relative positioning coordinates acquired, a value representative of the time of acquisition, and
an aquatic installation local physical and/or chemical state information aggregation means (125), configured to associate timestamped coordinates to a local measured physical and/or chemical state.-

摘要： The aquatic total alkalinity measurement system (100) comprises:
a pH probe (105) configured to measure pH at the boundary layer of a body of water,
a probe controller (115), configured to sequentially activate and deactivate, or connect and disconnect, the pH probe,
a pH measurement variation detection device (120), configured to detect a variation of pH measurement in a sequence of pH probe measurements, and
an aquatic total alkalinity value determination device (125), configured to determine an aquatic total alkalinity value of the body of water as a function of the pH measurement variation detected, and
preferably a total alkalinity regulation unit, configured to increase or decrease the total alkalinity of the body of water as a function of the measured total alkalinity value and a target total alkalinity value.
