Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
Please refer to fig. 1, which is a flowchart illustrating an implementation of a method for batch processing SWCC model parameter data based on RETC software, the implementation includes the following steps:
1. sorting and extracting SWCC model parameter data, splitting the extracted data to obtain a plurality of text files (please refer to FIG. 2 for a specific data file preparation flow chart);
currently, in practice, to realize batch calculation of SWCC curve model parameters, data is prepared first, and in an actual project, a database is usually collected, which includes hundreds of sample data. Therefore, before processing, the embodiment considers that the extracted data is split according to the preset number, so as to obtain a plurality of text files, wherein the file name of each text file is named according to the preset number so as to be distinguished.
As shown in fig. 2, after data in a database such as ACCESS is acquired, each sample data (i.e., SWCC curve model parameter) is split into a txt text file, and the file of each text file is named according to a sample number, as shown in the figure, after the data is split, a text file named by a file name of 0003 number, a text file named by a file name of 0002 number, and a text file named by a file name of 0001 number are obtained.
Meanwhile, when the RETC software is operated to calculate SWCC curve model parameters, the parameters required by the software are the soil negative pressure value and the soil volume water content value, and must be presented in an array mode of n rows and 3 columns, so the format of the data stored in each file needs to be set as: the first column records the negative pressure value of the soil, the second column records the volume water content value of the soil, and currently, the third column which records the weight occupied by each row of data can be considered in adding one column. In summary, in the present step, when the extracted data is split, the extracted data is considered to be split according to the preset number, and it is ensured that the data in each text file is divided into two rows according to the format of "retc.in", where the first row records the negative pressure value of the soil, and the second row records the volume water content of the soil.
2. Running RETC software, sequentially calling a text file comprising SWCC model parameter data, and writing data in the text file according to a format of RETC.IN; when the software runs, traversing all text files, and writing the data volume of each text file and SWCC data included in each text file into a RETC.IN file; specifically, the method comprises the following steps:
when the RETC software is used, when parameters are input, the RETC software generates an retc.in file according to the input parameters, software default values and the like, so that the current parameter values required to be input are recorded in the retc.in file, a user only needs to change the parameters required to be changed, and other parameters are kept unchanged according to the original file;
meanwhile, according to the requirement, the parameter value of the soil moisture characteristic curve model "MType" can be modified, please refer to table 1, wherein "MType" is listed, that is, the corresponding values of different SWCC models:
TABLE 1
Wherein the first column records the negative pressure value of the soil, the second column records the volume water content of the soil, and the third column records the parameter value of the curve model MType.
When the software runs, each text file is sequentially accessed, and the soil negative pressure value and the soil volume water content of each sample in the file are obtained. When a data file is read each time, the retc.in file needs to be rewritten according to the RETC input file retc.in data format, and parameters needed for calculation are changed according to calculation needs, and the parameters needed to be calculated specifically include: a parameter value of a soil moisture characteristic curve model MType required to be calculated; the data volume of the data of the actually measured soil moisture characteristic curve of the sample, the actually measured soil moisture characteristic curve data and the weight of each data point. In files can now wait to be called and executed by RETC software after modification of the RETC.
3. After the data writing operation is executed, the execution parameter calculation operation of the RETC software is operated, the SWCC model parameters are summarized and calculated from a calculation output file-RETC.OUT file, and finally result data are output according to the calculation result; reading an RETC.OUT file in a text format, traversing file matching characters according to an arrangement format of data in the RETC.OUT file, positioning a required SWCC model parameter result, writing the result data into an output file A by a character string splitting function when extracting the result data after positioning, and traversing the file A; in the traversing process, whether the data written in the file A is the result data required to be output is judged according to the storage form of the data in the file, and the result data required to be output is saved and summarized in an additional mode, so that batch processing of the SWCC model parameter data is completed; specifically, when the above method is executed by RETC software:
after the retc.in file is prepared, running an executable file (retc.exe) of RETC software, at this time, popping up a RETC software window, at this time, using a code simulation mouse to perform a click operation, sequentially clicking a button "retentioncurredata", a window retentioncurredata button "Next", a window RETC guide button "OK", and when the operation is performed to this step, generating a "RETC calibration" operation frame, optionally, providing two methods to continue the operation:
(a1) calling a system 'virtual keyboard' application program, simulating a mouse to click an 'Enter' key, and executing 'Press Enterprise continuous' operation; (a2) embed VBS code or call the VBS file "CreateObject (" wscript. shell "). SendKeys" { Enter } ", implement the" Enter "key, complete the RETC software run.
When the execution parameter calculation operation of the RETC software is operated, the software can automatically call an RETC.IN file, and the RETC.OUT file is output after calculation; after the RETC software is finished running, the RETC calculation result is stored in the retc.out file under the same path of the retc.in file, and the retc.out file can be read in a text format at present.
In order to locate the result data, in this embodiment, it is considered that the line where the required data is located by traversing the file matching characters according to the data arrangement format in the retc.
As for the result of the parameter simulation Value, optionally, the position of the line "Variable Value S.E.Coeff.T-Value Lower Upper" below "Nonlinear least-squares" can be located, and the line of the parameters ThetaR, ThetaS, Alpha and n can be obtained. As shown in FIG. 4, in order to extract the second column of data below the alignment line "Nonlinear least-squares analysis: final results", this embodiment provides two possible methods:
(1) respectively writing the located line data into an Excel table by a split () function, if the required parameter is a second column of the table given by the retc.
And finally, writing the separated parameter values into an Excel file in an additional mode, and quickly finishing the summary of the calculation results of the RETC software.
The execution flow of the method can refer to fig. 3, the first processing step in fig. 3 is to locate the required data, and after the data is located, the located row data is processed by a split () function, wherein the split () function can be used for splitting the character string, slicing the character string by a designated delimiter, and returning to a partitioned character string list;
after the character string is sliced, whether the character string meets the specific arrangement structure condition of the required data is judged, and if the character string meets the specific arrangement structure condition, the required parameter value is stored in an Excel file, so that the analysis process of the output structure is realized.
(2) Directly copying the positioned row data to an Excel table H below, and then performing batch operation in the Excel by using the following pre-programmed VBA macro codes, wherein the pre-programmed VBA macro codes refer to:
