Description

Technical Field

[0001] The present invention relates to the field of smart city management, and in particular to a strategy identification system for smart city management. Background Art

[0002] In the field of smart city management, the management experience of coastal cities is different from that of inland cities. Different coastal cities are different from each other. Some cities have more sand on the beach. The beach is formed by the accumulation of sand along the waterside or the flat land above the water surface in the water. Sand refers to small stones or things that look like sand. It also refers to imperfect flaws. The coarseness of sand refers to the average coarseness of sand particles of different particle sizes mixed together. Usually there are coarse sand, medium sand and fine sand. The particle grading of sand refers to the matching ratio of sand particles of different sizes. If the sand is of the same coarseness, the void is the largest. When two kinds of sand are matched, the void is reduced. When three kinds of sand are matched, the void is even smaller. It can be seen that the void ratio of sand depends on the matching degree of each grade of sand. Well-graded sand can not only save cement, but also improve the density and strength of concrete and mortar. The coarseness of sand is expressed by the fineness modulus Mx. The larger the fineness modulus, the coarser the sand. According to the range of fineness modulus, sand is divided into coarse sand, medium sand, fine sand and extra fine sand.

[0003] When the wave height near the beach exceeds the set wave height threshold, it is necessary to prohibit the hull from entering the sea area near the beach. For example, the invention application CN115541177A discloses an intelligent wave height meter system and control method that can automatically measure. The intelligent wave height meter system consists of a wireless camera, a WiFi wireless network, a wave height detection module, a wave height measurement module, and a wave height meter. When the model wave test is carried out, the intelligent wave height meter system automatically measures the wave height of the test condition, starts measuring synchronously when the wave generation starts, and stops measuring synchronously after the wave generation ends; no special personnel are required to operate the wave height measurement work during the test. It can be seen that due to the limited wave height detection mechanism near the beach, the only remaining wave height detection mechanism is not accurate enough, resulting in a lack of key data for the management of the traffic environment near the beach, which is prone to misjudgment in management. Summary of the invention

[0004] In order to solve the technical problems in related fields, the present invention provides a strategy identification system for smart city management, which can determine wave height data that is monotonically positively correlated with the reference height value obtained by visual analysis, and when the determined wave height data exceeds the set wave height threshold, a signal prohibiting the entry of the hull is issued, and when the determined wave height data does not exceed the set wave height threshold, a signal allowing the hull to enter is issued, thereby realizing reliable identification and effective execution of the ship entry strategy into the beach water area.

[0005] According to the present invention, a strategy identification system for smart city management is provided, the system comprising: A dynamic trigger mechanism is arranged on a beach at a coastline, and is used to sense an audio signal in the environment in which it is located, and issue a first processing instruction when the amplitude of the water phonon signal parsed in the audio signal is greater than or equal to a set amplitude limit; and issue a second processing instruction when the amplitude of the water phonon signal parsed in the audio signal is less than the set amplitude limit; A bird's-eye view imaging mechanism is wirelessly connected to the dynamic trigger mechanism, and is used to perform bird's-eye view imaging processing of the sea area in front of the beach at the coastline when the first processing instruction is wirelessly received, so as to obtain and output a corresponding picture of the sea area in front; A bilateral filtering device, arranged in a control room on the beach and connected to the overhead imaging mechanism, is used to perform bilateral filtering on the received front sea area image to obtain and output a corresponding bilateral filtered image; a maximum filtering device, connected to the bilateral filtering device, for performing maximum filtering processing on the received bilateral filtering image to obtain and output a corresponding maximum filtering image; A data sharpening device, connected to the maximum filtering device, for performing a spatial differential sharpening process on the received maximum filtering image to obtain and output a corresponding data sharpened image; A water body detection device is arranged in the control room on the beach and connected to the data sharpening device, and is used to identify each water body pixel point in the received data sharpening image based on the brightness value distribution range of the water body, analyze each imaging depth of field value corresponding to each water body pixel point, and output the difference between the maximum value and the minimum value of each imaging depth of field value as a reference height value; a strategy identification device connected to the water body detection device, and used to determine wave height data that is monotonically positively correlated with the reference height value, and to issue a signal prohibiting the entry of the vessel when the determined wave height data exceeds a set wave height threshold, and to issue a signal allowing the vessel to enter when the determined wave height data does not exceed the set wave height threshold; Among them, determining wave height data that is monotonically positively correlated with the reference height value, and issuing a signal prohibiting the entry of the hull when the determined wave height data exceeds the set wave height threshold, and issuing a signal allowing the hull to enter when the determined wave height data does not exceed the set wave height threshold includes: the value of the set wave height threshold is between 1.2 meters and 1.5 meters.

[0006] Therefore, the present invention has at least the following beneficial technical effects: First, bilateral filtering equipment, maximum filtering equipment and data sharpening equipment are used in sequence to improve the image quality of the overhead imaging images of the sea area in front of the beach at the coastline, thereby providing reliable basic information for subsequent depth of field detection; Second, based on the distribution range of the brightness value of the water body, the pixels constituting the water body in the received data sharpening image are identified, the imaging depth values ​​corresponding to the pixels constituting the water body are analyzed, and the difference between the maximum value and the minimum value of the imaging depth values ​​is output as the reference height value; The third part: determining the wave height data that is monotonically positively correlated with the reference height value obtained by visual analysis, and issuing a signal prohibiting the entry of the hull when the determined wave height data exceeds the set wave height threshold, and issuing a signal allowing the hull to enter when the determined wave height data does not exceed the set wave height threshold, thereby realizing reliable identification and effective execution of the ship entry strategy into the beach waters.

[0007] The strategy identification system for smart city management of the present invention is compact in design and intelligent in operation. Since it can determine the wave height data that is monotonically positively correlated with the reference height value obtained by visual analysis, and send a signal prohibiting the entry of the ship when the determined wave height data exceeds the set wave height threshold, it can realize reliable identification and effective execution of the ship entry strategy for the beach water area.
