In the paper,a patient intelligent care system is designed.The system connects patients,wards and nurse stations to achieve real-time collection of patient information,and summarizes the information summary to the nurse station to achieve intelligent care.The system mainly includes three modules:wearable device,terminal device and cloud platform.It has four functions:collecting physiological information of patients,networking transmission information,summarizing and processing information and summarizing display.On the hardware,the CH32V103 of RISC-V architecture is used as the main control chip,which is equipped with sensors,Bluetooth and wireless network chips.Finally,the MQTT communication protocol is used to upload the data to the Ali cloud IoT platform.It has been verified that the system can effectively detect the physiological information of patients,and can provide early warning,which can effectively help doctors and nurses to take care of patients.
