Control method and control system of high-flux water purifier capable of intelligently monitoring water quality

Abstract

The invention relates to a control method and a control system of a high-flux water purifier capable of intelligently monitoring water quality, and relates to the field of water treatment technology, the method comprises the following steps: obtaining TDS detection parameters; determining a permeation working pressure range corresponding to the TDS detection parameters according to the pressure matching relationship, determining a use working pressure in the permeation working pressure range, and controlling the RO membrane to be adjusted to the use working pressure; after the RO membrane is adjusted to the use working pressure, a detection time window with the width being the detection time length is constructed, and the detection water flow amount is obtained in the detection time window; determining TDS detection parameters and reasonable water flow flux corresponding to the use working pressure according to the flux matching relation; performing difference calculation according to the reasonable water flow flux and the detected water flow flux to determine a water flow deviation flux; and outputting a device abnormal signal when the water flow deviation flux is greater than the permissible deviation flux. The water purifier has the effect of conveniently monitoring the state of the TDS sensor in the water purifier in real time.
