摘要
详细介绍隧道施工过程中多元信息的自动采集、无线传输、预警及安全管理系统的关键技术与方法,采用无线技术把三维激光扫描、人机定位、各种传感器数据采集、通讯视频及安全管理集成在一起,实现隧道施工掌子面图像实时采集、显示与编录分析、掌子面稳定性监测、掌子面人员与车辆定位管理;实现隧道必测项目与断面扫描技术的结合预测围岩变形和超欠挖;实现选测断面各种传感器的无线数据采集与综合分析。在危险临近时,利用多元信息预警、计算分析、专家经验,结合系统的通讯卡、有源定位卡及警灯鸣笛等安全提示信息,启动四级预警及相应应急预案,疏导人员撤离,从而形成隧道施工多元信息全方位安全保障系统。这对隧道施工的动态设计、施工现场全方位高效直观管理及提高施工过程的安全度等具有重要的现实意义。
This paper introduces multivariate information automatism collection, wireless transmission, forewarning, safety management, etc. and key technologies of TMIGS, and it uses wireless communication to combine three-dimensional laser scanning, personnel equipment orientation, all kinds of sensor data collection, communication video and safety management to realize tunnel construction face image collection, display, edit and analysis, and construction face stability monitoring and personnel orientation management. And certain tunnel measuring item and section scanning technology are combined to forewarn around rock distortion and exceed, lack digging, and all kinds of sensors of selected measuring section of wireless data collection and synthesis analysis are brought forward. While danger is approaching tunnel, TMIGS can compute, analysis, awake, forewarn and startup emergency plan class IV in advance to guarantee worker safety to maximum extent. TMIGS has an important meaning for dynamic design and general supervision, and it enhances safety degree in tunnel construction.
