This utility model discloses a toll station card dispensing machine, comprising: a chassis with a built-in controller and an opening on one side; an aerial imaging device installed inside the chassis, comprising a housing, an imaging lens, and a display screen, both located within the chassis, with the imaging lens facing the opening; signal light emitted from the display screen is projected onto the imaging lens, and the signal light passes through the imaging lens to form a real image in the air that is mirror-symmetrical to the display screen; and a card receiving and dispensing device installed on the side of the chassis facing the lane, communicating with the aerial imaging device, containing a card, and positioned within the chassis but adapted to carry the card out of the chassis. The toll station card dispensing machine according to this utility model has advantages such as improving vehicle traffic efficiency, alleviating traffic pressure, and increasing user safety.

The application discloses a method and device for identifying road congestion state in real time, equipment and storage medium. Including: obtaining trajectory data corresponding to an idling vehicle equipped with a front image device, filtering a target vehicle driving on a road based on the trajectory data; extracting the front view image of the target vehicle, inputting the front view image into a pre-trained traffic object recognition model, and outputting the traffic object recognition result in the image; based on the traffic object recognition result, filtering an initial congestion image and automatically labeling the traffic light category corresponding to the initial congestion image; based on the traffic light category, inputting the initial congestion image into the corresponding congestion recognition model, and outputting the congestion level determination result of the current vehicle. Through image data recognition and congestion level recognition, the application accurately determines the congestion level, improves the accuracy and real-time performance of congestion recognition, provides strong support for traffic management and optimization, and improves road traffic efficiency.

The application discloses a core concrete pouring operation platform based on a large-cantilever cover beam U-shaped thin-wall shell, and aims at solving the problem of operation difficulty in core concrete pouring of the U-shaped thin-wall shell. The application comprises a steel bracket installed on the top of the cover beam shell body, the upper part of the steel bracket is provided with an operation platform, the steel bracket comprises longitudinal steel supports symmetrically arranged on the two sides of the U-shaped shell body, multiple transverse steel supports are arranged along the length direction of the cover beam shell body, and the multiple transverse steel supports are cross-sectioned with multiple angle steel support frames in the inside of the cover beam shell body. The operation platform is suitable for core concrete pouring operation of a large-cantilever prefabricated thin-wall cover beam formwork, has the advantages of convenient installation and removal, stability and reliability, and greatly simplifies the high-altitude operation link through optimization of the construction process, thereby improving the construction efficiency and operation safety.
