It is an important indicator to describe the degree of inflation and affects the government's formulation of monetary, fiscal, consumption, price, wage, social security and other policies.

[0135] The distance reference impact value refers to the maximum impact value that the upper plate pressing position can tolerate when there is a distance deviation between the deviation position and the shape center position. The distance reference impact value is obtained after pre-input by the operator. By judging whether the center deviation distance impact value is less than the preset distance reference impact value, it is judged whether the upper plate can be directly adjusted.

[0136] Step S4672: Continue to execute step S469.

[0137] When it is less than, it means that the upper plate can be used for direct adjustment at this time, so continue to execute step S469.

The month-on-month replacement value is determined by analyzing the deviation month information and the historical same period month information, and replacing the month-on-month data corresponding to the deviation month information with the month-on-month data corresponding to the historical same period month information. The month-on-month replacement value is then combined with the month-on-month value of the measurement time to form the month-on-month adjustment information, thereby improving the accuracy of the obtained month-on-month adjustment information.

[0277] Furthermore, in order to further ensure the rationality of the month-on-month replacement value, it is necessary to conduct further separate analysis and calculation of the month-on-month replacement value, which is explained in detail through the following steps.

[0278] The method for determining the month-on-month replacement value includes the following steps:

[0279] Step S54351: Based on the historical information of the same period of months, retrieve the month-on-month value and the individual value of the same period of months.

[0280] The month-on-month value of the same period refers to the month-on-month value corresponding to the same period, and the individual value of the same period refers to the individual value of the same period that can be retrieved in historical time. The month-on-month value and the individual value of the same period are retrieved through the historical information of the same period, which is convenient for subsequent use.

[0281] Step S54352: Determine whether the number of months in the same period is less than the preset reference number of months in the same period. If yes, execute step S54353; if no, execute step S54354.

[0282] The benchmark value of the same period month refers to the minimum value corresponding to the same period month required for further analysis. The benchmark value of the same period month is obtained after pre-input by the operator. By judging whether the value of the same period month is less than the preset benchmark value of the same period month, it is judged whether it can be directly replaced.

[0283] Step S54353: Use the month-on-month value of the same period as the month-on-month replacement value.

[0284] When the value of the same period month is less than the preset benchmark value of the same period month, it means that it can be directly replaced at this time, so the month-on-month value of the same period month is used as the month-on-month replacement value.

[0285] Step S54354: Obtain measurement subject information.

[0286] The subject information of the calculation refers to the subject information corresponding to the current CPI calculation, which can be a company or an individual. The subject information of the calculation is obtained after the operator pre-enters it.

[0287] Step S54355: Retrieve the calculation subject demand information based on the calculation subject information.

[0288] The measuring subject demand information refers to the accuracy requirement information needed by the measuring subject when calculating the CPI. The measuring subject demand information is retrieved through the measuring subject information to facilitate subsequent use.

[0289] Step S54356: Based on the demand information of the measuring subject, the historical information of the same period of the month is selected as the selected month information, and the month-on-month value of the same period corresponding to the selected month information is used as the month-on-month value of the selected month.

[0290] The selected month information refers to the month information after selecting the months of the same period. The historical information of the same period of months is selected by calculating the subject demand information and used as the selected month information, and the month-on-month value of the selected month is defined to facilitate subsequent use.

[0291] Step S54357: Determine the selected month adjustment value based on the selected month information and the selected month month-on-month value analysis, and use the selected month adjustment value as the month-on-month replacement value.

[0292] The selected month adjustment value refers to the adjustment value for the month-on-month adjustment based on the selected month. The selected month information and the month-on-month value of the selected month are analyzed to determine the selected month adjustment value, and the selected month adjustment value is used as the month-on-month replacement value, thereby improving the accuracy of the obtained month-on-month replacement value.

[0293] Furthermore, in order to further ensure the rationality of the selected month adjustment value, it is necessary to perform further separate analysis and calculation on the selected month adjustment value, which is specifically explained in detail through the following steps.

[0294] The method for determining the selected month adjustment value includes the following steps:

[0295] Step S543571: based on the selected month information, retrieve the selected month individual value and the selected month month-on-month value.

[0296] The individual value of the selected month refers to the individual value corresponding to the selected month, and the month-on-month value of the selected month refers to the month-on-month value corresponding to the selected month. The individual value of the selected month and the month-on-month value of the selected month are retrieved by selecting the month information to facilitate subsequent use.

[0297] Step S543572: Determine whether the selected month value is only one. If yes, execute step S543573; if no, execute step S543574.

[0298] By judging whether the selected month value is only one, it is determined whether further calculation is required.

[0299] Step S543573: based on the selected month information, retrieve the month-on-month value at the end of the same year, and use the month-on-month value at the end of the same year as the adjustment value for the selected month.

[0300] The year-on-year value of the month at the end of the same year refers to the year-on-year value of the last month of the year corresponding to the selected month information. When the selected month value is only one, it means that no further calculation is required at this time. Therefore, the year-on-year value of the month at the end of the same year is retrieved by selecting the month information, and the year-on-year value of the month at the end of the same year is used as the selected month adjustment value for subsequent use.

[0301] Step S543574: Calculate the average of the month-on-month values ​​of the selected month and use it as the month-on-month average.

[0302] The month-on-month average refers to the average of the month-on-month values ​​of the selected month. When the number of values ​​in the selected month is more than one, it means that further calculation is needed. Therefore, the average of the month-on-month values ​​of the selected month is calculated and used as the month-on-month average for easy subsequent use.

[0303] Step S543575: Sort the month-on-month values ​​from large to small based on the selected month, and obtain the maximum month-on-month value and the minimum month-on-month value based on the sorting result.

[0304] The maximum month-on-month value refers to the maximum month-on-month value in the selected month, and the minimum month-on-month value refers to the minimum month-on-month value in the selected month. The month-on-month values ​​of the selected months are sorted from large to small, and the maximum and minimum month-on-month values ​​are obtained based on the sorting results, which is convenient for subsequent use.

[0305] Step S543576: Calculate the difference between the maximum month-on-month value and the minimum month-on-month value and use it as the month-on-month deviation value.

[0306] The month-on-month deviation value refers to the deviation value when there is a deviation in the month-on-month value. The difference between the maximum month-on-month value and the minimum month-on-month value is calculated and used as the month-on-month deviation value for easy subsequent use.

[0307] Step S543577: Determine the month-on-month deviation impact value corresponding to the month-on-month deviation value according to the corresponding relationship between the month-on-month deviation value and the preset month-on-month deviation impact value.

[0308] The month-on-month deviation impact value refers to the impact value generated when there is a month-on-month deviation. The month-on-month deviation impact value is obtained by querying from a database that stores month-on-month deviation values ​​and month-on-month deviation impact values. The database is obtained and stored through experiments. The month-on-month deviation impact value is determined by querying the month-on-month deviation value for subsequent use.

[0309] Step S543578: Calculate the sum of the month-on-month average value and the month-on-month deviation impact value and use it as the month-on-month average adjustment value, and use the month-on-month average adjustment value as the selected month adjustment value.

[0310] The month-on-month average adjustment value refers to the adjustment value after adjusting the month-on-month average value. The month-on-month average adjustment value is calculated by taking the sum of the month-on-month average value and the month-on-month deviation impact value as the month-on-month average adjustment value, and the month-on-month average adjustment value is used as the selected month adjustment value, thereby improving the accuracy of the obtained selected month adjustment value.
