Water-related security disposing and serving method and device

The invention provides a water-related security disposing and serving method and device applied to a network formed by a vehicle and a cloud server. The disposing and serving method comprises the steps that water-level out-of-limit messages are received from a water-level detection module; whether the water-level out-of-limit messages are received in multiple continuous detection periods or whether the water-level out-of-limit messages are received for specific times within a specific time period is judged; a water-related danger prompt message is output through an output device inside the vehicle when the vehicle is in the traveling state; a water-related danger alarm message is sent to the cloud server when the vehicle is in the parked state; the cloud server inquires a preset vehicle-user relation table according to the vehicle logo, determines the user corresponding to the vehicle and sends the water-related danger prompt message to the user. Compared with the prior art, the water-related security disposing and serving method and device have the advantages that a water-related danger can be sensed in time, and the user can be helped in learning the water-related danger of the vehicle in time through the cloud server.
