Embodiment Construction
[0017] figure 1 The working principle of the system and the installation position of the edge nodes are explained. Camera 1 is an edge node, including a camera, a processor, and a wireless module. The camera takes pictures of the car and is a sensor for perception. The processor interprets the photos to extract the license plate number and uses it as edge computing power. The wireless module is used to connect to the cloud server 4 , transfer the calculation result. The camera can be a permanent device without a GPS module. During installation, the builder uses a GPS handheld terminal to locate the device, and the cloud server marks the coordinates of the handheld terminal on the electronic map to confirm the exact location of the permanent device. The camera can also be a temporary device. After the application is installed on the mobile phone, it is temporarily placed at a specified location. The GPS coordinates and data packets of the camera are sent to the cloud server th...

According to the invention, cameras are arranged on street lamps and vertical rods of a street or a community, a parking area is accurately divided into a plurality of search areas, the cameras shoot and identify license plate numbers, vehicles are positioned through license plate photographing, and further, the cameras also serve as edge computing power to count the number of vehicles entering a certain search area, the parking condition of each search area is judged according to the positive and negative difference between the parking space number and the statistical number, and a calculation result is sent to a cloud server through a wireless signal. A real-time and reliable parking space searching and automatic timing management platform is constructed, vehicle searching and parking space searching services are provided for vehicle owners, parking management and self-service charging are completed for municipal departments, and the management level of a smart city is effectively improved.
Description
(1) Technical field [0001] The invention divides the search area by the camera and combines the counting and statistics of the license plate, and is a management platform for vehicle positioning and parking space search in a smart city. The system sets up cameras on street lamps and poles in streets or communities, accurately divides the parking area into multiple search areas, and photographs and recognizes license plate numbers, and counts the number of license plates entering a certain search area, based on the statistics and the number of parking spaces. Calculate the number of empty parking spaces, and then send the packaged data to the cloud server. The electronic map in the background marks the geographic location of all cameras, and then determines the position of the car through the search area divided by the cameras. The present invention is an innovative application combining software-defined Internet of Things and edge computing, and builds a city-level sensor and ...
