Abstract

The invention discloses a method for screening process parameters of dredging yield or energy consumption based on a main base analysis method. The method comprises the following specific steps: Step1: collecting data of the yield and process parameters in the dredging operation, determining p analysis variables, and listing the sample matrix of the dependent variable and the independent variable, wherein p is a positive integer; 2, carrying out standardization treatment on that relevant process parameter data; Step 3: Using Gram-Schmidt orthogonal transformation to construct the main base variable; Step 4: Screening the obtained main base variables and select the process parameters with high correlation with the yield. The invention utilizes the main substrate analysis method and adoptsGram-Schmidt orthogonal transformation to construct the matrix of principal and base variables, and screens out the parameters which have great influence on the yield or energy consumption. It can provide a method for optimizing the output or energy consumption of dredging operation to achieve the purpose of high output, and it is of great significance to determine the process parameters that affect the output in dredging operation.

Description

technical field [0001] The invention relates to a dredging production or energy consumption process parameter screening method based on a main base analysis method, and belongs to the field of dredging engineering. Background technique [0002] Dredging engineering is an important project of water conservancy and water transportation engineering, which plays a very important role in the progress of human society, environmental improvement and economic development. Modern dredging projects are mainly carried out by dredgers, and there are many process control parameters. In the current stage of dredging operations, manual operations are mainly used. Even for experienced operators, due to many influencing factors, qualitative testing is relatively difficult, and dredging operations have always been in a state of high energy consumption and low output. Therefore, it is particularly important to search for technological parameters related to the output of dredging operations. ...
