Method and system for controlling salt chlorine generation and salt chlorine generator

A system for controlling salt chlorine generation, comprising:

• a data obtaining module, configured to obtain a water quality parameter and climate data;
• a control module, configured to determine, according to the water quality parameter, whether a concentration of a chlorine disinfection constituent in water meets a standard;
• and if the concentration meets the standard, skip starting an electrolysis apparatus/procedure;
• or if the concentration does not meet the standard, start the electrolysis apparatus/procedure, and calculate a power supply time of the electrolysis apparatus according to a concentration difference value of the chlorine disinfection constituent, to form a control instruction;
• wherein, the control module is configured to perform the calculation of the power supply time of the electrolysis apparatus according to the concentration difference value of the chlorine disinfection constituent by calculating the power supply time t of the electrolysis apparatus within each power supply cycle according to N*Δconcentration/m, wherein N is a total duration of the power supply cycle, m is a preset parameter less than N, and Δconcentration is the concentration difference value of the chlorine disinfection constituent;
• a weighting module, configured to determine a weighting value according to the climate data, to fine-tune the control instruction;
• wherein, the weighting module is configured to perform the determination of the weighting value according to the climate data by comprehensively processing a sunshine intensity and an ultraviolet index, classifying obtained weighting values into a plurality of levels, and adding the weighting value within a set range to the power supply time corresponding to the control instruction;
• and
• an execution module, configured to control the electrolysis apparatus by using the fine-tuned control instruction;
• wherein, the climate data comprises the sunshine intensity and the ultraviolet index.
