Problems solved by technology

This driving method causes the two electrodes to undergo oxidation and reduction reactions respectively, resulting in polarization. The surface of one electrode is oxidized, and the conductive area is changed, which affects the measured conductance value, resulting in serious errors in the TDS value.

Abstract

The invention relates to a TDS (Total Dissolved Solid) detection method and device and belongs to the field of communication. The method comprises the following steps: setting first alternating voltage and second alternating voltage, wherein in the same alternating period, a high electrical level time period of the first alternating voltage and a high electrical level time period of the second alternating voltage have no overlapping; and when a TDS detection probe is used for carrying out TDS detection in a water path to be detected, applying the first alternating voltage and the second alternating voltage to two electrodes of the TDS detection probe respectively to carry out the TDS detection. The device comprises a first setting module and a triggering module. According to the TDS detection method and device provided by the invention, the two electrodes of the TDS detection probe can be effectively prevented from a polarization phenomenon by the alternating voltage so that the probe can stably and reliably work for a long period, errors are reduced and the TDS detection accuracy is improved.

Description

technical field [0001] The present disclosure relates to the field of smart homes, and in particular, to a total dissolved solids (Total Dissolved Solids, TDS for short) detection method and device. Background technique [0002] TDS, also known as total dissolved solids, is measured in milligrams per liter (mg / L), which indicates how many milligrams of dissolved solids are dissolved in 1 liter of water. The TDS value represents the impurity content of dissolved substances in the water. The larger the TDS value is, the larger the impurity content in the water is. On the contrary, the smaller the impurity content in the water. TDS detection is widely used in the field of water treatment, and more and more household water purifiers begin to add TDS online detection function to realize real-time monitoring of the water quality of the water purifier. [0003] The main process of TDS detection is to insert a pair of electrodes in the water. After electrification, under the action...
