Supervision and control system for tunnel boring machine (TBM)

According to the request of the upper workstation, the visualized supervision and control system for shield tunnel boring machine (TBM) is developed. The hardware design and software structure are proposed. Specially, logical judgment of working state and static and dynamic prediction model of earth surface level variation are given and analyzed in the thesis. The solutions to avoid land surface sedimentation accruing are brought forward: ensuring the working state of the programs precisely at any time according as 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 put forward in this paper can supervise multi-subject, can forecast exactly, as well as can realize visualized evaluation and prediction on line.
