Operation method and system for numerical analysis of water hardness

Abstract

The invention relates to an operation method and system for numerical analysis of water hardness. The method comprises the following steps that: S1, a detecting device acquires to-be-analyzed data x and transmits the to-be-analyzed data x to a mobile phone client; S2, the mobile phone client extracts constants C1, C2, C3, and C4 from a server, wherein the constants C1, C2, C3, and C4 are dynamic values that are stored in the server and participate in change management according to the updating of the research equipment and the research result; S3, the mobile phone client substitutes the to-be-analyzed data x and the constants C1, C2, C3, and C4 into the following calculation formula: ppm=exp(C1*x+C2)-C3*(1-1 / (1+exp(-x / C4))); and the value of the water hardness in a test solution is calculated and the numerical result is displayed at the mobile phone client. Therefore, the constants C1, C2, C3, and C4 are always kept to be latest values and thus the synchronization and accuracy of theanalysis results are ensured; and with the analysis mode of the general formula, the large data comparison table is simplified into simple mathematical calculation, so that production and use of thedetecting device become convenient.

Description

technical field [0001] The invention relates to the technical field of water hardness detection, in particular to an operation method and system for numerical analysis of water hardness. Background technique [0002] The hardness of water refers to the total concentration of calcium and magnesium ions in water, including carbonate hardness (that is, calcium and magnesium ions that can be precipitated in the form of carbonate by heating, so it is also called temporary hardness) and non-carbonate hardness ( That is, the part of calcium and magnesium ions that cannot be precipitated after heating, also known as permanent hardness). [0003] The hardness of water is closely related to our life. People have also developed various methods for measuring water hardness, usually complexometric titration, spectrophotometry, atomic absorption, ion chromatography, etc. In order to improve production efficiency, researchers have successively developed A variety of water hardness testing...
