Drowning of water vehicles frequently occur during the rainy seasons. Several reasons exist behind such drowning. Among them, swing for the brutal current is mentionable. If there would be a technique, which can raise an alarm after reaching a risky level of swing during the brutal current, then the drivers as well as the passengers of the water vehicle can be alert and prepare for necessary actions such as not moving more forward to avoid an upcoming drowning. To the best of our knowledge, such a technique is yet to be proposed in the literature. Therefore, in this paper, we attempt to propose such a technique. In doing so, we measure horizontal and vertical angles and if the measurements exceed certain threshold levels, we propose to generate an alarm. We determine the swing, i.e., the angles, using a 3-axis accelerometer. We perform real testbed experimentation using the 3-axis accelerometer and determine the threshold levels, which are the key parameters of our proposed technique. |
