摘要
针对传统病房监护系统中存在的弊端,提出一种利用无线传感器网络(WSN)构建病房监护系统的设计方案。利用TI公司的ZigBee单芯片解决方案CC2430和适量外围电路设计传感器节点,ST公司的STR912处理器及适量外围器件设计中心控制节点,结合红外收发模块实现对患者房间级的定位。采用TI公司的ZigBee协议栈作为WSN节点软件平台,嵌入式实时操作系统μC/OS-II、TCP/IP协议栈LwIP构建网关软件开发平台,实现了利用TCP/IP模块进行数据的可靠传输以及链路维护等功能。
For the drawbacks in traditional system a ward monitoring system employing wireless sensor network（WSN） is proposed.The sensor node is designed with TI Company＇s single chip ZigBee SoC CC2430 and moderate peripheral circuit,while the hardware circuit of the central control node designed with ST Company＇s STR912 processor.Patients＇ visual positioning at room level is achieved with infrared transceiver module.The system software platform is composed of TI＇s ZigBee protocol stack,real-time operation system,μC/ /OS-II,TCP/IP stack LwIP.The TCP/IP model is used to ensure the reliable transmission of data,as well as link maintenance.
