【摘要】 文中在探讨地铁隧道安全的基础上,构建一种基于Zig Bee无线传感器网络的地铁隧道倾角和振动的低功耗系统,并对该系统的体系结构进行了详细的论述。由于供电条件限制,系统设计了Router节点低功耗电路。经测试表明,该无线传感器网络工作正常,达到预期目标。更多还原

【Abstract】 This paper describes a WSN system based on Zig Bee protocol in detail. The WSN system is applied to measure the inclination and vibration of the subway tunnel for the safety reason. A low-power Router circuit is designed because of the limitation of power supply. The testing result shows that the WSN system works properly and meets the design requirement.更多还原
