Abstract:

A wireless drowning features recognition system is designed to meet the application requirements of automatic monitoring swimming states.The system is not only capable of real-time monitoring of the status of swimmers accurately and automated without affecting normal swimming,but also of abnormal alarms.The system hardware consists of signal acquisition and pre-processing module,a wireless transmission module and control module.The main part of the algorithm contains serial data receiver module,data preprocessing module,drowning feature recognition module and the control module.Drowning feature recognition module is based on the artificial immune clonal selection algorithm,which has a natural recognition features pattern that can easily extract features that are difficult to extract by other recognition algorithms.Experiments show that the system can accurately and quickly identify the characteristics of non-drowning and drowning.
