Abstract

The invention discloses a liquid level monitoring system which comprises a control circuit, a liquid level sensor connected with the control circuit and a detection circuit connected with the liquid level sensor and the control circuit, wherein the control circuit is used for supplying power to the liquid level sensor under the condition that a detection signal which is sent by a user and represents the detected target liquid level is received, the control circuit stops supplying power to the liquid level sensor under the condition that a stop signal which is sent by a user and represents that detection of the target water level is finished is received, and the detection circuit is used for detecting the target liquid level through the liquid level sensor under the condition that the control circuit supplies power to the liquid level sensor. The control circuit supplies power to the liquid level sensor according to the received detection signal and stops supplying power to the liquid level sensor according to the received stop signal, so that the problem of supplying power to the liquid level sensor for a long time is avoided, the time of oxidation reaction between various impurities contained in liquid and the liquid level sensor is shortened, and therefore, the service life of the liquid level sensor is prolonged.

Description

technical field [0001] The present application relates to the technical field of power electronics, in particular to a liquid level monitoring system. Background technique [0002] With the development of science and technology, in order to improve the accuracy of water level judgment in the production environment, liquid level sensors and detection circuits have become an indispensable link in the detection of water levels such as farm water levels, sewage treatment water levels, and reservoir water levels. [0003] At present, the liquid level monitoring system includes a power supply, a detection circuit and a liquid level sensor. In the process of using the water level detection circuit to detect the water level, the negative pole of the liquid level sensor is connected to the water level, the positive pole is connected to the positive pole of the power supply through a current limiting resistor, and the detection circuit is connected to the positive pole of the liquid l...
