摘　　要：提出一种用于地震条件下石墨堆内构件的动力学响应检测的无线加速度传感器,并且能够对地震条件下石墨结构的完整性做出明确的评价。检测结果表明,在满足抗震实验各种工况条件下对无线加速度传感器的检测结果与有线加速度传感器检测的结果是一致的。该无线检测技术避免了传统的基于有线网络的石墨结构检测系统的安装费用高、可靠性差、安全性差等缺点。A method for wireless acceleration sensor for detecting the dynamic response of the graphite reactor internals under earthquake conditions is proposed, and it can make a clear assessment of integrity of the graphite structure under seismic conditions. Test results show the consistence of the detection result of wireless acceleration sensor and the cable acceleration sensor detection when all the conditions for the seismic experiments are satisfied. The wireless detection technology avoids the disadvantages of high installation cost, and poor reliability and safety of the graphite structure detection system based on the traditional wired network.
