Description

Technical Field

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

[0002] With the progress of urbanization, smart urban management has become a specialized discipline. However, the conditions of cities are different. Some cities are located in plains, some are located in mountainous areas, and some are even located on the seashore. In view of these different conditions, the management situation must change, and various new technologies must be adopted.

[0003] Visual analysis can be applied to various data sets and fields, such as business analysis, healthcare, environmental analysis, financial analysis, operations management, etc. In the current rapid development of big data and artificial intelligence, visual analysis has become increasingly important, helping people better understand and apply massive data and information, thereby making better decisions and predictions.

[0004] Visual analysis first requires clarifying the goals and problems, then selecting the appropriate visualization form, then performing data preprocessing, data visualization and data exploration, and finally interpreting and analyzing the resulting graphics and information. Visual analysis relies on the visual perception of the human eye and the cognitive and judgment abilities of the human brain, and is usually an intuitive, intuitive and effective data analysis method.

[0005] Visual analysis can be applied to various sub-sectors, such as the traffic management of docks in coastal cities. Different docks require different ship lengths for throughput. If the distribution length corresponding to the current ship to enter is greater than the maximum allowable passing length of the dock, the ship should be prohibited from entering the dock. Otherwise, the ship should be allowed to enter the dock. However, there is a lack of corresponding solutions in the existing technology. Summary of the invention

[0006] In order to solve the technical problems in the prior art, the present invention provides a smart city management system, which can execute a no-entry warning operation corresponding to the excessive length when the distribution length corresponding to the hull of the visual analysis is greater than the maximum allowable passing length of the dock, and is also used to temporarily suspend the execution of the no-entry warning operation corresponding to the excessive length when the distribution length corresponding to the hull of the visual analysis is less than or equal to the maximum allowable passing length of the dock.

[0007] According to the present invention, a smart city management system is provided, the system comprising: The bird's-eye view acquisition device is used to acquire image data of the waters near the dock using a bird's-eye view camera upon receiving a ship approach signal, wherein the ship approach signal includes coded data of the latest ship entering the dock; An edge sharpening device, connected to the bird's-eye view acquisition device, is used to perform edge sharpening processing on the received bird's-eye view image of the water area to obtain and output a corresponding edge sharpened image; A guided filtering device, connected to the edge sharpening device, for performing a guided filtering process on the received edge sharpening image to obtain and output a corresponding guided filtered image; a band-stop filtering device, connected to the guided filtering device, for performing a band-stop filtering process on the received guided filtering image to obtain and output a corresponding band-stop filtered image; A visualization measuring device is connected to the band-stop filter device and includes an information capturing device, a focal length acquisition device and a content conversion device. The content conversion device is connected to the information capturing device and the focal length acquisition device respectively. The visualization measuring device is used to record the image block where the hull is located in the band-stop filter image, determine the total number of pixels occupied in the length direction of the geometric shape corresponding to the image block where the hull is located, analyze the distribution length corresponding to the hull based on the total number of pixels and the imaging focal length of the band-stop filter image, and send a transformation detection signal when the deviation between the distribution length corresponding to the hull and the factory hull length of the hull type corresponding to the coded data of the hull that has recently entered the dock exceeds a set deviation value. Any one of the parameters of the total number of pixels and the imaging focal length of the band-stop filter image is monotonically positively correlated with the distribution length corresponding to the hull; A no-go warning device is connected to the visual measurement device and is used to execute a no-go warning operation corresponding to the length exceeding the limit when the distribution length corresponding to the analyzed hull is greater than the maximum allowable passing length of the wharf; The no-go warning device is also used to suspend the no-go warning operation corresponding to the length exceeding the limit when the distribution length corresponding to the analyzed hull is less than or equal to the maximum allowed passing length of the dock.

[0008] Therefore, the present invention has the following outstanding technical effects: Technical effect A: A visual measurement device including an information capture device, a focal length acquisition device and a content conversion device is used to provide hardware resources for converting the visual data of the length of the hull into physical data; Technical effect B: the image block where the hull is located in the band-stop filter image is recorded, the total number of pixels in the length direction of the geometric shape corresponding to the image block where the hull is located is determined, and the distribution length corresponding to the hull is analyzed based on the total number of pixels and the imaging focal length of the band-stop filter image, and any one of the parameters of the total number of pixels and the imaging focal length of the band-stop filter image is monotonically positively correlated with the distribution length corresponding to the hull; Technical effect C: When the distribution length corresponding to the hull of the visual analysis is greater than the maximum allowable passing length of the dock, the no-entry warning operation corresponding to the length excess is executed; and when the distribution length corresponding to the hull of the visual analysis is less than or equal to the maximum allowable passing length of the dock, the no-entry warning operation corresponding to the length excess is temporarily suspended.

[0009] The smart city management system of the present invention has compact logic and is easy to operate. When the distribution length corresponding to the visually analyzed ship hull is greater than the maximum allowable passing length of the wharf, the prohibited warning operation corresponding to the length exceeding the limit is executed, otherwise, the prohibited warning operation corresponding to the length exceeding the limit is temporarily suspended, thereby improving the intelligent level of wharf management.
