Earth pressure balance shield tunneling machine, propelling speed prediction method and device for earth pressure balance shield tunneling machine and storage medium

Abstract

The invention discloses a propelling speed prediction method and device for an earth pressure balance shield tunneling machine, a computer readable storage medium and an earth pressure balance shield tunneling machine. The method comprises the steps that: a speed prediction model is obtained by training an autoregression model structure with exogenous variables based on historical input and output data of a propulsion speed subsystem of the earth pressure balance shield tunneling machine in advance; the speed prediction model uses a multi-layer perceptron to fit nonlinear regression parameters of the autoregression model structure with the exogenous variables; propelling data information of the earth pressure balance shield tunneling machine before the current moment is obtained; the propelling data information is input into the speed prediction model; and the propelling speed of the earth pressure balance shield tunneling machine is determined according to an output result of the speed prediction model. The speed prediction model can describe the dynamic characteristics of the propelling speed of the earth pressure balance shield tunneling machine, so that a basis is provided for self-adaptive adjustment of the operation parameters of the earth pressure balance shield tunneling machine, and the construction safety is effectively improved.

Description

technical field [0001] The present application relates to the technical field of automation control, in particular to a method and device for predicting the propulsion speed of an earth pressure balance shield machine, a computer-readable storage medium, and an earth pressure balance shield machine. Background technique [0002] The earth pressure balance shield machine has been widely used in the large-scale construction of underground infrastructure such as subways and tunnels due to its low interference to the environment and its advantages of high efficiency, safety, and environmental protection. The basic working principle of the earth pressure balance shield machine is: when the earth pressure balance shield machine is pushed forward by the propulsion hydraulic cylinder, the rock and soil cut by the cutter head are modified and filled with the airtight cabin and the screw conveyor shell. At the same time, relying on the filled modified soil to balance the water and soi...
