摘　　要：膨胀节是一个具有使用寿命的结构元件,当膨胀节的使用达到一定时间后,膨胀节就会发生失效。文章设计开发了一种基于无线传感网络的膨胀节在线监测系统,将物联网、大数据以及分布式软件等热点技术与膨胀节产品有机结合。通过试验测试及工程应用,能够有效地实时监测产品的运行工况,并进行预警及报警。The expansion joint is a structural element with limited service life.After the expansion joint has been used for a period of time,it will be fail.In this paper,an online monitoring system of the expansion joint was designed and developed by using wireless network sensing technology.The expansion joint were organically combined with the hot technologies such as IOT,big data and distributed software,etc.By experiment and engineering applications,the operating conditions of the expansion joint can be effectively real-time monitoring,and early warnings and alarms can be performed.
