Abstract:

A drowning prevention system is designed to reduce personal loss caused by drowning.The system uses the Internet of Things (IoT) related technologies such as ZigBee,GPS and GPRS to link the terminal and location information service platform,and to provide remote location tracking,monitoring scheduling,information management,resource sharing and other functions for rivers,lakes and other areas prone to drowning.The system has the same structure as the IoT:the perception layer,server layer,network layer and sensing layer.CC2420 is used to simulate the information communication between the drowning prevention gateway device and the reference node.The simulation result shows the ability of the system to monitor and manage the areas of frequent accidents well and to reduce the occurrence of drowning events from the source.

Key words: ZigBee technology;location technology;drowning prevention system
