Research And Development Of Bluetooth Respiration Monitoring And Alarm System For 3-6 Yeats Old Children'S Swimwear

Although swimming is a very healthy sport.But for children with a poor sense of self-protection,swimming is also an extremely dangerous sport.Drowning has become the leading cause of unnatural death in children.This has spurred the rapid growth of the swimsuit market.Following the new development direction of smart clothing,this paper intends to develop a bluetooth respiratory monitoring and alarm system for children's swimsuits aged 3-6 years.When children wear swimsuits,the signal acquisition module on the swimsuit can collect their respiratory signals,send them through bluetooth technology and display them at the receiving end.To reflect the breathing state of children in the swimming pool,improve the safety of children in swimming.Firstly,this paper introduces the research background and development status of breathing monitoring intelligent equipment at home and abroad,as well as the market status of children's swimsuits.Respiratory monitoring points and alarm parameters of children's respiratory frequency during swimming were established through relevant medical literature and reports.Secondly,the hardware of respiratory monitoring system is designed.The hardware monitoring system includes breath signal acquisition module,driver module,battery module and bluetooth module.MEMS sensor is adopted to collect respiratory signals,and STM32 core single chip is used as the central control module to drive each module to transmit signals to the mobile phone client through bluetooth technology.Finally,based on the analysis of existing data,the design principles of children's Bluetooth breathing monitoring swimsuit are drawn up,and the wearability of three fabrics are tested.Finally,the fabric,style and size specifications of children's swimsuit are determined.The Bluetooth breathing monitoring system is combined with the designed swimsuit for children.The whole smart clothing is tested.The function,stability and accuracy of the monitoring are tested.The results are in line with the expected goals.
