摘要
针对掘进机施工对上位机监控系统的要求,研究开发了可视化的监控系统.介绍了该系统的硬件组成及软件结构,重点分析了程序运行状态的确定及地表沉降静、动态预测模型,提出了行之有效的解决方法,即依据掘进机各施工环节的运行状态,利用状态逻辑图,准确地确定了程序任一时间的运行状态;采用在线评估和对地表的静、动态预测方法及可视化手段较准确地预测出地表的沉降量.实践表明,该系统检测对象多、预测数据准确,且可实现可视化的在线评估及预测.
Visualized supervision and control system for shield tunnel boring machine was developed, according to the request of the upper workstation. The hardware design and software structure were introduced. Specially, logical judgment of working state and static and dynamic prediction model of earth surface level variation were given and analyzed. The solutions to avoid land surface sedimentation accruing were brought forward: ensuring the working state of the programs precisely at any time according to running state of the tunneling machine with using logical judgment formula; forecasting the quantities of the surface sedimentation comparatively exactly by evaluating on-line and visualized supervision means. It is testified that the system can supervise multi-subject, can forecast exactly, as well as can realize visualized evaluation and prediction on line.
