Problems solved by technology
[0004] The inventor found that the above-mentioned prior art focuses on monitoring whether the water quality exceeds the standard through the traditional instrument monitoring method, that is, the monitoring method of the flow meter. The detection method is single, and the instrument detection unit needs to be regularly maintained, and the personnel maintenance cost is relatively high.
It is impossible to observe the drainage situation of the drainage outlet in real time through the equipment, and it is still necessary to go through the on-the-job inspection method, and the inspection personnel will go to the site to confirm the discharge situation of the rain drainage outlet, and the operation and maintenance methods are relatively backward

Embodiment Construction
[0056] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.
[0057] Considering that the existing technology focuses on monitoring whether the water quality exceeds the standard through the traditional instrument monitoring method, that is, the flow meter monitoring method, the detection method is single, and the instrument detection unit needs to be maintained regularly, and the personnel maintenance cost is high. It i...

The embodiment of the invention provides a rainwater discharge outlet management and control method, device and system, and the method comprises the steps: receiving discharge outlet video monitoring information sent by a video monitoring device, the video monitoring device is corresponding to the central point of a discharge outlet and is perpendicular to the tangent plane of the discharge outlet, and the edge side of the discharge outlet is provided with a light-emitting lamp strip; performing image comparison according to the image brightness of the light-emitting lamp strip in the discharge outlet video monitoring information and the image brightness of the light-emitting lamp strip of a preset discharge port reference image when no water is discharged, and determining the water discharge state of the discharge outlet; when the discharge outlet is in a discharge state, identifying the width of a drainage interface in the video monitoring information of the discharge outlet, and judging whether sewage is discharged in a mixed manner at the discharge outlet according to the width of the drainage interface and a width threshold value of the drainage interface, and if so, sending a gate closing working signal to a gate of the discharge outlet. According to the invention, environmental protection management and control can be efficiently and accurately carried out on the rainwater discharge outlet.
Description
technical field [0001] The present application relates to the field of water resources protection, in particular to a method, device and system for controlling rainwater outlets. Background technique [0002] Rainwater outfall management is often overlooked as an important part of corporate environmental protection management. The main reason is the lack of standardized and process-oriented management measures. It is known accurately that it can only be found on the spot through regular inspections. On the other hand, the management measures are not comprehensive, and the treatment measures are not timely. When environmental inspectors find that the drainage water quality exceeds the standard, a large number of unqualified water bodies have already been discharged into relevant rivers and canals, making management difficult. For companies that install detection instruments at rainwater outlets, most of them use ultrasonic flowmeters to determine whether there is rainwater ...
