基于Web的盾构机盾尾变形远程监测系统

Remote Monitoring System of Shield Tail Deformation of Shield Machine Based on Web

由于盾尾属于薄壁部件,在土体压力下容易发生变形。为了实时监控盾尾产生的形变,提出一种盾尾变形远程监测方法,并开发了相应的监测系统。该系统主要包括应变采集模块、云计算中心和可视化模块,通过应变采集模块将采集的原始应变数据通过TCP协议传输至云计算中心进行信号滤波,并采用并发多线程服务器提高数据吞吐率,计算得到的变形数据以Web网页形式进行可视化展示。经过3个月的实践证明,Web终端在高负载情况下仍保持较低的延迟,平均响应时间为150ms,系统稳定可靠。

Shield tail is a thin-walled component,it is easy to deform under soil pressure.In order to monitor the deformation of shield tail in real time,a remote monitoring method of shield tail deformation is proposed,and the corresponding monitoring system is developed.The system mainly includes strain acquisition module,cloud computing center and visualization module.Through the strain acquisition module,the collected original strain data is transmitted to the cloud computing center through TCP protocol for signal filtering,and the concurrent multithreaded server is used to improve the data throughput.The calculated deformation data is visually displayed in the form of Web pages.After three months of practice,it is proved that the Web terminal still maintains a low delay under high load,the average response time is 150ms,and the system is stable and reliable.
