Water level monitoring device and method

Abstract

The present invention discloses a water level monitoring device and method, and belong to the field of smart water conservancy and water level monitoring in the water conservancy industry. The water level monitoring device comprises a vertical bracket, a horizontal bracket and a water level ruler fixedly connected with the channel wall; the vertical bracket is fixedly connected with the horizontalbracket, and a first rib is also connected between the vertical bracket and the horizontal bracket; the outer wall of the vertical bracket is also connected with an equipment box, and the top outer wall of the vertical bracket is connected with a light sensor; the outer wall of the horizontal bracket is connected with a sliding module, and the bottom outer wall of the sliding module is also connected with an industrial camera; the outer wall of the industrial camera is connected with a liquid level sensor, and a protective sleeve is arranged on the outer wall of the liquid level sensor; and the bottom of the horizontal bracket is also connected with a support rod, and the bottom of the support rod is connected with a non-contact water level gauge. According to the device and method provided by the present invention, integrated structure design is adopted, on-site installation is facilitated, and high reliability, a low cost and easy popularization are achieved.

Description

technical field [0001] The invention relates to the technical field of intelligent water level monitoring in the water conservancy industry, in particular to a water level monitoring device and method. Background technique [0002] With the continuous development and progress of the social economy, the status of water conservancy in the national economy is becoming more and more important. The safe operation and management of water conservancy projects have become the top priority of the water conservancy industry and the driving force for digitalization of water conservancy. As the basic data of water conservancy, water level data is an indispensable and important parameter in the digital construction of water conservancy. For water level monitoring of rivers, lakes, reservoirs, channels and other water conservancy projects, it is particularly important to obtain water level data in a timely and accurate manner. Moreover, there are many water level monitoring stations, and ...

Problems solved by technology

Pressure-type water level sensors need to be placed at the bottom of rivers, lakes, reservoirs, channels, etc., and rely on water pressure data to reflect the water level, which is easy to enter sediment and cause inaccurate measurement, requires regular maintenance, and is not easy to install and maintain; The non-contact water level gauge is easy to install and has high measurement accuracy, but it is mainly imported. On the one hand, the cost is high, and it cannot be installed in large quantities. On the other hand, the measurement data will drift for a long time. Maintenance; the non-contact type also relies on image recognition technology to collect water level, which is generally realized by using a nearby security monitoring dome camera to identify the water level scale scale. Although it is technically feasible, it affects security monitoring and the price is very high. In addition, it is serious at night or in bad weather. Affects water level recognition, so it cannot meet the needs of digital water conservancy
