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

Embodiment 2
[0044] refer to Figure 5 , a water level monitoring method, the following steps are used to operate:
[0045] S1, firstly, the sliding module is fixedly connected to the horizontal support 2, and then the bottom plate 101 is fixedly connected to the shore by bolts;
[0046] S2, observe the height of the water level through the non-contact water level gauge 201;
[0047] S3, start the stepper motor 501 to make it drive the screw rod 502 at the output end to rotate, so that the threaded block 503 drives the push rod 6 to move, so that the liquid level sensor 602 drops until the water level is lifted;
[0048] S4, the water level scale is photographed by the industrial camera 601, thereby monitoring the height of the water surface water level;
[0049] S5, comparing the monitoring results of the two, analyzing and obtaining the precise water level height.
[0050] In the present invention, first, the single-chip microcomputer module controls the non-contact water level gauge ...

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 ...
