摘　　要：针对目前建设高速公路桥梁时,T梁架设完全依赖操作者的经验和观察,容易造成架设时间长,架设质量低的问题,论文设计了一种基于窄带物联网的全自动T梁架设系统。采用窄带物联网(NB-IoT)通信技术,将传感器,通信模块集成为基站子系统,安装于架桥机上的特定位置,通过自主设计T梁位置检测方法和云平台数据算法处理实现架桥机的全自动运行和T梁的自动架设。与传统方法相比,该监测系统具有测量精度高、时效性好、结构简单的优点。系统测试结果表明,系统的测距范围为0.045~30m,测量精度为±2mm,达到了降低T梁架设过程的安全风险、提高效率的目的。In the current construction of expressway bridges,the erection of T-beams completely depends on the experience and eye observation of the operator,which may easily lead to the problems oflong erection time and low erection quality.In this paper,a fully automatic T-beam erection system based on the narrowband Internet of Things is designed.Sensors and communication modules are integrated into a base station subsystem by using Narrow Band Internet of Things(NB-IoT)communication technology.The base station subsystem is installed at a specific position on the bridge erection machine.And then,the automatic operation of the bridge erection machine and the automatic erection of the T-beam are realized by means of the self-designed T-beam position detection method and the cloud platform algorithm.Compared with the traditional method,the monitoring system designed in this paper possesses the advantages of high measuring accuracy,good timeliness and simple structure.The test results show that the measuring range of the system is from 0.045~30 m,and the measuring accuracy is±2 mm.The designed system achieves the purpose ofreducing the safety risk and improving the efficiency of the T-beam erection process.
