A kind of tbm intelligent driving method and system

Abstract

The invention proposes a TBM intelligent driving method and system. The steps of the method are: the TBM tunneling parameter intelligent decision-making unit predicts the current surrounding rock state parameters according to the equipment operating parameters, real-time perception of the TBM tunneling environment, and the predicted tunneling parameters; online monitoring system Real-time detection of hob force, cutterhead vibration, equipment operation parameters and slag image, and transfer feature information to fuzzy control logic library; fuzzy control logic library converts feature information into adjustment value and adjustment step of tunneling control parameters ; When the tunneling control parameters, hob force, cutterhead vibration, equipment operation parameters and slag image analysis results are all in a steady state, the TBM intelligent driving system reaches a steady state. The present invention feeds back real-time relevant feature information to the fuzzy control logic library through online monitoring of hob force, cutterhead vibration, slag image analysis, and equipment operation main parameters, and gives the adjustment value and adjustment step of the control parameters. Through closed-loop feedback Realize intelligent driving.

Description

technical field [0001] The invention relates to the technical field of tunnel excavation equipment construction automation, in particular to a TBM intelligent driving method and system. Background technique [0002] The hard rock tunnel boring machine (hereinafter referred to as the hard rock TBM) is a large-scale high-tech construction equipment specially used for excavating rock tunnels and underground passages. In the traditional construction method, the driver in the main control room evaluates the surrounding rock state parameters through a slow trial excavation process, and then adjusts the excavation parameters repeatedly until the excavation parameters remain stable. On the one hand, such an operation method will consume a lot of construction time due to the continuous slow trial excavation and repeated adjustment of the excavation parameters. The parameters cannot adapt to the current driving environment, resulting in abnormal wear of the tool and the decline of th...
