摘要
目的为了解决医院人工看护成本高、医疗器械监护接线繁多等缺点,设计了基于Zig Bee无线传感网络的光电脉搏心率监测系统。方法该系统以Zig Bee无线传感网络作为通信载体,以自组网的方式监控无线网络节点。系统终端节点监测病人的心率等生命体征数据,通过路由节点将心率数据逐级转发至监控中心。监控中心节点汇总并保存监测数据。结果完成了无线传感网络中各节点的软硬件设计以及监护中心上位机软件设计。结论经实验调试该监护系统能达到设计预期效果,并且具有低成本、易于维护、工作稳定等特点。
Objective To deal with the high cost of hospital human care and the trouble of varied wiring of the equipment, a photoelectric pulse rate monitoring system based on ZigBee wireless sensor network was designed in this paper. Methods The ZigBee wireless sensor network was used in this system as the communication car- rier and the wireless network nodes were monitored by ad-hoc network. The heart rate and other vital signals of the patients were monitored by the system terminal nodes and the monitoring data were forwarded to the moni- toring center by routing nodes. The monitoring data were collected and stored in the central node. Results The hardware and software of the wireless sensor network were successfully designed. Conclusion After experimen- tal debugging, the monitoring system achieved the design objective. It has the advantages of low cost, easy maintenance and long-term stability.
