In view of the single function and the expensiveness of the stroller on the market,the study designs intelligent stroller system.Through taking intelligent stroller with low power consumption and high-performance AT89C51 MCU as the main control unit,the study uses Keil5 software as the development environment,and selects cost-effective sensors to form a small Internet of Things system,so as to fully meet the needs of modern consumers,to ensure the safety of infants and children.The intelligent stroller system detects the changes in real-time weather,shades the baby when the light intensity exceeds the set threshold,and lower the shed when the rainfall is too heavy to ensure that the baby is not wet.When the system detects that the baby is in a dangerous state,the intelligent brake module is activated to protect the baby's safety.When the baby wets the bed,the alarm device is activated to remind the parents to change the diaper in time.Through the test analysis,the intelligent stroller system can run smoothly,providing convenience to consumers while improving the comfort and safety of the baby.
