Abstract

The invention discloses a liquid level data detection device and method. The device comprises an ultrasonic sensor, a controller and an ultrasonic wave-focusing cover; the ultrasonic wave-focusing cover comprises a curved surface; the controller is connected with the ultrasonic sensor; a concave surface of the curved surface is opposite to the ultrasonic sensor, and the concave surface of the curved surface can emit the ultrasonic wave emitted by the ultrasonic sensor in parallel along a first reflecting beam direction, and the ultrasonic wave entering the concave surface along the first reflecting beam direction can be focused to the ultrasonic sensor. The technical problem that the liquid level data detected in the prior art is inaccurate since the ultrasonic second reflecting wave energy value in the prior art is small is solved, and a technical effect of improving the accuracy of acquiring the accurate liquid level data at the to-be-detected water area is reached.

Description

technical field [0001] The invention relates to the field of drainage pipe networks, in particular to a liquid level data detection device and method. Background technique [0002] With the development of science and technology, there is an increasing demand for liquid level monitoring in municipal and water conservancy fields such as rainwater, sewage, reclaimed water, rivers, lakes, and roads. In recent years, waterlogging events have occurred in many cities in my country during the rainy season every year, showing the characteristics of a wide range of occurrences, a large depth of water accumulation, and a long time of water accumulation. The occurrence of waterlogging incidents not only brings inconvenience to people traveling in rainy days, but also leads to huge losses of personal and public property, and even threatens the safety of people's lives, which has aroused widespread concern from all aspects of society. [0003] Accurate monitoring of liquid level data is ...
