Split-type wireless liquid level detection system and its electro-corrosion suppression method

Abstract

The invention discloses a split type wireless liquid level detection system and an electric corrosion suppression method thereof. The system is composed of a display terminal, an acquisition terminal and a liquid level gauge. The liquid level gauge converts the liquid level state into a resistance state and is connected to the collection terminal through two signal lines. A wireless transmission module is arranged in the collection terminal, and the liquid level state information collected by the collection terminal is passed through the wireless transmission module. Upload to the display terminal. The effect is: change the reference resistance of the liquid level gauge into a built-in installation, only need two signal lines for external connection, add a collection terminal with wireless transmission function to the entire detection system, use wireless transmission to simplify the trouble of wiring, expand At the same time, the acquisition terminal can be used to change the potential polarity of the two signal lines to achieve the effect of inhibiting electrical corrosion.

Description

technical field [0001] The invention relates to liquid level detection technology, in particular to a split type wireless liquid level detection system and an electric corrosion suppression method thereof. Background technique [0002] For the liquid level detection of conductive liquids, electrode type liquid level gauges are mostly used for detection. By setting detection electrodes of different heights, in the detection circuit, each electrode is connected with a corresponding resistor. When the detection electrodes are connected by liquids of different heights When submerged, different resistance combination states can be reflected in the detection circuit, and the corresponding liquid level height can be obtained by judging the resistance value of the liquid level gauge through the circuit, thereby realizing liquid level detection. [0003] However, the problem existing in the prior art is that usually only detection electrodes are provided in the liquid level gauge, an...
