Description

Technical Field

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

[0002] Parking space, also known as parking space, refers to the place where parking is carried out, including open-air and indoor places. Parking spaces can be divided into two types according to the charges, free parking spaces and paid parking spaces. In parking lot management, the main source of income for parking lot management companies is to provide parking services through renting parking spaces and collecting parking fees. Parking spaces are often divided into fixed parking spaces and temporary rental parking spaces.

[0003] Many places with large flow of people and frequent business exchanges have above-ground and underground parking lots to save space. Parking spaces are usually marked on both sides of urban planned roads or in open areas to provide convenience for drivers to park. However, if you park in a place without a parking space in the city, it can be regarded as illegal parking and you can be fined. At present, these have been included in the key management areas in the management of smart cities.

[0004] Obviously, parking spaces are high-risk places where vehicles are unattended and can be invaded or stolen. If there are human objects not related to the vehicle nearby, it is easy for invasion or theft to occur. However, the existing technology lacks targeted high-precision detection and early warning solutions, resulting in a response only after the vehicle is invaded or stolen. Summary of the invention

[0005] In order to solve the technical problems in related fields, the present invention provides a smart city wireless alarm system, which can determine whether the parking space-bound vehicle and the non-vehicle-associated human object are in an intertwined state based on the judgment result of whether the edge pixels of each of the imaging areas in the bilateral filtered image obtained after customized enhancement processing of the parking scene picture are within the imaging area of ​​each other, thereby improving the analysis accuracy of the intertwined state and providing reliable real-time data for the vehicle being invaded or stolen by others.

[0006] According to the present invention, a smart city wireless alarm system is provided, the system comprising: The flameout detection mechanism is arranged inside the vehicle, and is used to issue a first detection command when it is detected that the power device of the vehicle stops running, and is also used to issue a second detection command when it is detected that the power device of the vehicle does not stop running; A network monitoring mechanism, which is arranged just above the parking space bound to the vehicle and is connected to the flameout detection mechanism via a wireless communication network, and is used to start a visual monitoring operation of the scene where the parking space bound to the vehicle is located upon receiving the first detection command, so as to obtain and output a corresponding real-time monitoring image; A distortion processing device, which is arranged in a control box near the parking space bound to the vehicle and connected to the network monitoring mechanism, is used to perform distortion correction processing on the received real-time monitoring image to obtain and output a corresponding distortion processed image; a first filtering device, connected to the distortion processing device, for performing arithmetic mean filtering on the received distortion processed image to obtain and output a corresponding arithmetic mean filtered image; a second filtering device, connected to the first filtering device, configured to perform a bilateral filtering process on the received arithmetic mean filtered image to obtain and output a corresponding bilateral filtered image; an interlacing analysis device, arranged in a control box near a parking space bound to a vehicle and connected to the second filtering device, for obtaining an imaging area of ​​the vehicle bound to the parking space in a bilateral filtering image as a first target area, and obtaining an imaging area of ​​a non-vehicle-associated human object in the bilateral filtering image as a second target area, obtaining each edge pixel point of the first target area and each edge pixel point of the second target area, and issuing an interlacing detection command when an edge pixel point of the second target area falls within the first target area or an edge pixel point of the first target area falls within the second target area, and depth of field values ​​of the first target area and the second target area match; A wireless alarm device is connected to the interleaving analysis device and is used to compress and encode the bilateral filter image corresponding to the interleaving detection command and send it together with the abnormal scene alarm signal as wireless alarm data to a remote vehicle monitoring server when the interleaving detection command is received; Among them, when an interleaved detection command is received, the bilateral filtered image corresponding to the interleaved detection command is compressed and encoded, and then it is wirelessly sent to a remote vehicle monitoring server together with an abnormal on-site alarm signal as wireless alarm data. The method includes: when an interleaved detection command is received, the bilateral filtered image corresponding to the interleaved detection command is compressed and encoded, and then it is packaged into an IP data packet together with the abnormal on-site alarm signal as wireless alarm data and then wirelessly sent to a remote vehicle monitoring server.

[0007] It can be seen that the present invention has at least the following three important inventive concepts: Firstly: based on the judgment result of whether the edge pixel points of the parking space-bound vehicle and the non-vehicle-associated human object in the imaging area of ​​the bilateral filter image obtained after the parking scene image is customized and enhanced, it is determined whether the parking space-bound vehicle and the non-vehicle-associated human object are in an intertwined state, thereby improving the analysis accuracy of the intertwined state and providing reliable real-time data for vehicles being invaded or stolen by others; Secondly: when receiving the interweaving detection command, the bilateral filter image corresponding to the interweaving detection command is compressed and encoded, and then sent together with the abnormal scene alarm signal as wireless alarm data to a remote vehicle monitoring server, thereby realizing remote alarm when the vehicle is invaded or stolen by others; Again: after performing customized enhancement processing on the parking scene image, a bilateral filtering image with higher image quality is obtained, the customized enhancement processing includes continuously performing distortion correction processing, arithmetic mean filtering processing and bilateral filtering processing on the parking scene image.
