中文摘要：

针对工业和民用建筑物中各种储水设施数量大且分散及管理困难的问题，提出一种快速无线报警结构，中心节点采用SIM卡类型ZigBee模块，对传感器节点进行身份识别，与注册户身份相关联，使得某个储水设施泄漏时，系统直接将泄漏信息发送到相应注册用户的手机上，同时向相关事故处理部门报警。并提出多级循环比较算法，应用于系统决策环节。实验结果表明，该算法有效地提高了报警灵敏度，降低了误警率。在节点设计中，引入两种机制降低节点功耗，仿真结果显示节能效果显著。

英文摘要：

With an aim at the large number of various water storage facilities, of which the distribution is not centralized in the industrial and civil buildings, a fast warning system is proposed. To achieve fast warning function, the sink node employed a SIM card-type ZigBee module to notify the situation to the corresponding emergency office and registered users who have cellular phones, through SMS server of cellular network. Meanwhile, the multi-grade cycle comparison algorithm is presented to be adopted in the part of host making-decision. Experimental result indicates that it can improve the sensitivity of alarm and reduce the false alarm rate. To reduce power consumption of the sensor nodes, two mechanisms are employed. Simulation result shows that the energy reducing effect is significant.
