Abstract
In order to solve the problem of single function and low intelligence of traditional life jacket, an intelligent water life jacket system principle prototype is designed and developed. The system includes intelligent life jacket, OneNET Cloud Service Platform and mobile app. With MCU as the main control and water sensor as the falling water monitoring equipment, GPS real-time positioning information is uploaded to OneNET and mobile app through GPRS wireless, so as to realize the water safety monitoring and management of small and medium-sized waters. The simulation and field test show that the system can stably realize the functions of falling water detection, positioning, alarming and uploading. The working time of the whole process of the system is limited within 10 seconds, and the GPS precision is controlled within 10 meters. This project is expected to provide technical reference for the development of life-saving equipment and the safety management of small and medium waters, which has certain practical value.
