摘　　要：针对传统医院环境监测系统现场布线难、设备移动性差、测量精度不高的问题,提出了一种基于无线传感器网络(WSNs)技术的医院环境监测系统,并详细介绍了该系统的结构、通信机制及软件实现流程。系统由无线传感器节点依据无线通信机制形成WSNs。在分析影响WSNs能耗的主要因素和现有节能技术基础上,提出了一种基于能量均衡的数据可靠传输算法,即动态能量管理分簇算法(DPMCA),该算法把DPM技术和CA有效结合,有效解决了传统医院环境监测系统中存在的问题。Aiming at problems of traditional hospital environmental monitoring system,which are difficulty of addressing,poor mobility and measurement precision is not high,present a new hospital environmental monitoring system based on wireless sensor networks（ WSNs）,and introduce system structure,communication mechanism and flow chart of program in detail. Wireless sensor nodes form WSNs based on wireless communication mechanism. On the basis of analysis on main factors that influences energy consumption of WSNs and the existing energy-saving technology,propose a reliable data transmission algorithm,dynamic power management clustering algorithm（ DPMCA）,which is based on energy balance,it effectivly combines dynamic power consumption management technology with clustering algorithm. This system solves effectively problems in hospital environmental monitoring.
