基于WSN的婴儿实时监控系统的设计

Design of Real Time Monitoring System Based on WSN

目前医院对婴儿体温、哭闹、尿湿和心率等生理指标异常监控方法比较落后,需要大量的人力去监护,对此,可以将传感器技术与Zigbee相结合,构建无线传感器网络,应用于对婴儿的各项生理指标的实时监测.相关传感器采集各项生理指标数据,以TI的CC2530芯片为主控芯片,运行Zigbee协议栈,设计Zigbee转以太网网关,将Zigbee网络数据经以太网上传到上位机监护系统,从而实时的向医护人员报告婴儿的各项生理指标数据以及婴儿周边环境参数,如果数据异常,可实现自动报警,并保存历史数据.经过测试,本设计能够实现婴儿各项生理指标数据监测,系统工作稳定,网络通信正常,出现参数异常时能够及时准确报警.本设计验证了将无线传感器网络应用于婴儿监测的可行性与有效性.

In hospital, the method of body temperature,heart rate and other physiological indexes anomaly monitoring of the infant is relatively backward at present,which requires a lot of manpower.So,the sensor technology can be combined with Zigbee,which can construct wireless sensor network for physiological indexes real-time monitoring of infant.The relevant sensor can collect physiological index data,Zigbee protocol stack be worked on main control chip,which is TI＇s CC2530,and ZigBee Ethernet gateway is designed to transfer Zigbee network data,which can be uploaded to the computer monitoring system via Ethernet,then the physiological data of infant and parameters of the surrounding environment can be reported to health care workers at real-time.If the data is abnormal, it can realize the automatic alarm, and the preservation of historical data. After testing, the design can achieve the monitoring of physiological indicators of infants, the system is stable;network communication is normal; abnormal parameters can be timely and accurate alarm. The design verifies the feasibility and effectiveness of the application of wireless sensor networks in infant monitoring.
