Abstract: In order to solve the society's demand for long-term and continuous ward monitoring, a ZigBee-based ward monitoring system is proposed. The system implements the collection of the ward environment and the patient's physiological parameters and uses the ZigBee technology to integrate and transmit data of the sensors.The nurse station management platform is developed to monitor and manage the information of each ward and patients, and integrates the ward environment, patient information and management background. Experiment indicates that this system can achieve stable communication for more than 24 hours in a 30 m²room, and the error rate of data is less than 2. 5% , which meets the daily monitoring and management needs of ordinary wards.
