The invention provides a multi-
sensor fusion falling-into-water monitoring method,
system and device and a storage medium, a water sensor, a real-time positioning module and a
gyroscope respectively collect data from three dimensions of falling-into-water, falling-into-
water area and falling-into-water speed, a multi-
modal data
closed loop is formed, core indexes of falling-into-water monitoring are fully covered, and the accuracy of falling-into-water monitoring is improved. The water falling categories are classified, and monitoring is more comprehensive and accurate compared with monitoring of a single sensor; through multi-
signal cross validation, states such as falling-into-water
false alarm and the like are effectively resisted; the three sensors are small in size, can be integrated into a certain intelligent device, are non-inductive to carry, improve the use comfort and compliance of a user, are suitable for old people with weak
physical strength, and can continuously monitor the safety state for a long time; multi-
sensor fusion has a
data redundancy design, when a certain sensor breaks down or is interfered, data of other sensors can still maintain a basic falling-into-water monitoring function, monitoring continuity and reliability are guaranteed, and monitoring interruption caused by the problem of a single sensor is avoided.
