Research and Design of Wireless Medical Monitoring System Based on ZigBee

ZigBee technology has caused the high attention of people since its advent, and it is one of wireless technologies, spreading the world very quickly. Because of its characteristics of short range, low rate, low power consumption, large network capacity, self-organizing and self-healing, it is introduced in medical monitoring system. In this system, the communication standards between nodes and gateways are 802.15.4/ZigBee. Besides, the system hardware platform uses the chip of TI's CC2530, and software platform is developed based on TI's Z-Stack protocol stack. The physiological data of human body which are collected with the temperature and pulse sensors are transferred to the hospital through the transmission of wireless network, and eventually these data are used for diagnosing and analyzing condition of patients. From the test of results of the sensor network, it indicates that the data collecting by sensor of nodes is precise and the data transmission of wireless network is reliable.
