Embodiment 1

[0040] Figure 1a and 1b It is a structural schematic diagram of the present invention, as shown in the figure, an automatic monitoring system suitable for shallow lake lake flooding, the system includes a support platform, protection facilities, power supply system, warning system, data acquisition system, data transmission system and data center.

[0041] The supporting platform must be higher than the historical highest water level in the water area where it is located. It is supported by five large-diameter steel piles 20 and six "work"-shaped steel beams 19, on which a stainless steel plate 17 (that is, the platform) is laid. At the same time, in order to facilitate the operation of the platform, A stainless steel ladder 18 is welded on one side of the stainless steel plate 17, and a small crane 11 is provided on the other side. This platform system can bear a huge load, can maintain sufficient stability under the action of wind turbine torque or typhoon and flood, and ca...

Embodiment 2

[0053] figure 2 It is a flow chart of the present invention, as shown in the figure, a method for automatic monitoring of lake flooding using the automatic monitoring system for algae-derived lake flooding of shallow lakes described in Embodiment 1, the method includes the following steps:

[0054] (1) Use the solar battery pack 13 to convert solar energy into electrical energy and store it in the battery pack 28 on sunny days; on cloudy days or at night, rely on the wind generator 5 to convert wind energy into electrical energy and store it in the battery pack 28; the battery pack 28 It is the power source of the data collector system (including beacon light 2, camera 3, weather sensor 8, water temperature-dissolved oxygen sensor 23, water quality sensor 25, hydrological sensor 27) and communication module 30;

[0055] (2) Use the camera 3 to collect video images of the water surface within a radius of 1 km; then, according to the characteristics that the occurrence of lake ...

Abstract

The invention discloses a system and a method for automatically monitoring the lake-flooding of a shallow lake; the system comprises a support platform, a power supply system, a data acquisition system, a data transmission system and a data center, wherein the support platform comprises a plurality of platforms supported by piles; the power supply system is used for supplying power for the data acquisition system and the data transmission system; the data acquisition system comprises a meteorological sensor, a hydrological sensor, a water quality sensor, a plurality of water temperature and dissolved oxygen sensors and a camera; and the data transmission system is connected with the data acquisition system, and is used for transmitting various lake-flooding information acquired by the data acquisition system into the data center with the data acquisition system. The system and the method are suitable for monitoring the algae-derived lake-flooding, which is comparatively fixed in occurrence site, high in frequency and short in duration, and difficult to catch by manual sampling or remote sensing inversion with low time resolution, of the shallow lake.

Description

[0001] technical field [0002] The invention belongs to the field of environmental monitoring, relates to an automatic monitoring system for shallow lake flooding, and also relates to an automatic monitoring method for lake flooding using the automatic monitoring system for shallow lake flooding. Background technique [0003] Lake flooding (also known as black water mass or sewage mass) refers to the eutrophic water body of a lake after a large number of algae outbreaks, accumulations, and death, under suitable meteorological and hydrological conditions, and the organic matter in the sediment under anoxic and anaerobic conditions. Under these conditions, biochemical reactions occur, releasing sulfides such as sulfide, methane, and dimethyl trisulfide, forming a brown-black "black water mass" with a foul smell, which leads to rapid deterioration of water quality and damages its ecosystem service value. This will have a negative impact on the economy and society. For example...
