摘　　要：为满足可靠保障消防现场消防员人身安全的要求,研制了消防员安全监测系统生理参数采集节点。节点采用高性价比的CC2430及传感器,实现对消防员生理参数及环境参数进行采集传输以实时监控消防人员的安全。然而节点中各类传感器对电压要求不同以及节点的能耗是影响节点可靠运行及电池使用效率的主要因素。设计了节点供电电源动态管理机制以提升节点的性能。实验结果表明该节点的电池使用效率比未进行电源管理的节点提高了80%。从而节点的性能得到大幅度的提升。To satisfy the requirement of ensuring firemen＇s security in fire field,this paper designed a RF monitoring node for checking physiological index of firemen.The node composed by high cost performance radio chip CC2430 and sensors acquire physiological index of firemen and environment parameters,and then the data will be transmitted to the base for monitoring firemen＇s safety.However,different kind of demanded supply voltage of sensors and high power consumption of nodes are main factors influencing reliability and battery efficiency of the node.This paper introduced a power consumption management mechanism in the design of node to enhance its performance.Experiment results show that the battery use efficiency of the node with dynamic power management is increased by 80% than that of without power management.
