Pool surveillance system and associated surveillance method

摘要

A system for surveillance of a pool containing a liquid such as water-comprises at least one first element comprising at least one submersible robot provided with standalone propulsion capabilities for propelling the robot in the pool, onboard of which robot is installed at least one sensor capable of producing at least one measurement of a quantity representative of at least one disturbance of the pool relative to a reference state, the first element being furthermore provided with communication capabilities for communicating, in the submerged position, with at least one second element, the system being configured to process, in processing means, the output of the at least one sensor and to trigger at least one action.

1. A method for surveilling a pool containing water on the basis of:
a plurality of submersible robots provided with wireless link means for communicating, in the submerged position, with at least one second element, said second element being one of said plurality of robots or a central unit configured to float on the liquid contained in said pool, and sensors capable of detecting at least one disturbance of said pool relative to a reference state being installed onboard said submersible robots; said method comprising: a step of detecting at least one disturbance of said pool relative to a reference state, said measurements being obtained from said sensors, a step of communication of said first element in the submerged position with at least one second element, a step of processing of the outputs of said sensors, to trigger at least one action of information on the disturbance of the pool relative to a reference state by means of information means, and a step of detecting an intrusion of a body in the water in which at least one sensor of said sensors produces, when detecting the intrusion of an individual in the water, a first alert signal A1 and a first probability signal PA1, PB1, PC1 representative of the probability with which the intrusion is likely to have really actually occurred, and, when a first alert signal A1 is produced by a first submersible robot, a confirmation step upon which a check is carried out, at least on the basis of a probability signal from at least one second submersible robot, as to whether the intrusion of an individual is confirmed by at least one second submersible robot.
