Abstract

The invention discloses a method for liquid level detection through sound wave transmission. The method includes the following concrete steps that hardware platform setting-up is achieved, particularly hardware used for implement of the method is set up, and electrodes used for transmitting and reflecting sound waves are placed in liquid; a gradient placing principle is adopted when the reflecting electrodes are placed, and namely the reflecting electrodes representing upper scale values are shorter than the reflecting electrodes representing lower scale values; sonar signals are generated; the sonar signals are transmitted; the sonar signals are received; the sonar signals are processed; liquid level confirmation is carried out, after the step of signal processing, a liquid level confirmation circuit is used for decoding and calculating dot signals to determine encoding information of the reflecting electrodes, and interval value information of a value of the liquid level where the reflecting electrodes are located is determined through comparison. The liquid level detection method is designed by means of the lossless transmission characteristic, in the liquid, of the sound waves and can detect the liquid level conveniently and fast.

Description

technical field [0001] The invention relates to the technical field of acoustic wave measurement, in particular to a method for liquid level detection by means of acoustic wave transmission. Background technique [0002] Sonar is the transliteration of the English abbreviation "SONAR". Its full name in Chinese is: Sound Navigation and Ranging, SoundNavigationAndRanging, which uses the propagation characteristics of sound waves under water to complete underwater detection and communication tasks through electro-acoustic conversion and information processing. Electronic equipment. It has two types, active and passive, and belongs to the category of acoustic positioning. Sonar is an electronic device that uses underwater sound waves to detect, locate and communicate underwater targets. It is the most widely used and most important in underwater acoustics. a device. [0003] Since the attenuation rate of electromagnetic waves in water is very high, it cannot be used as a signal...
