Design of multifunctional remote monitoring system for ward

Abstract

This paper designs a multi-functional remote monitoring system for wards based on single chip microcomputer (SCM). Taking STM32 SCM as the core, the system detects the patient's body temperature and heart rate, and sends the detection signals to the SCM using temperature sensor and heart rate sensor, which is displayed on the display module after analysis and processing. If the patient has abnormal conditions such as fever, too fast or too slow heart rate, the system would alert the patient through buzzer alarm, and send a warning on the mini program of the medical staff by WIFI to remind the medical staff to treat in time. The liquid status in the infusion bottle is monitored in real time by the liquid level sensor. When the liquid is almost finished, not only the buzzer sounds to remind the patient to close, but also the system can send the information to the mobile phone by WIFI to show that the liquid has been finished. The nurse can add medicine or take the needle to the patient in time. According to the mini program, the inclination angle that needs to be adjusted by the hospital bed can be selected on the mobile phone, and the motor can drive the hospital bed to adjust the corresponding angle. Patients can call the monitoring center by pressing the key if they have any other needs, and can have a direct conversation with the nurse or doctor in the monitoring center. The system has the functions of human-computer interaction, simple operation, remote monitoring and so on, which has a strong practical significance for real-time understanding of patients and improving the efficiency of treatment.
