Description

Technical Field

[0001] The utility model relates to the technical field of networked electronic toll collection (ETC), in particular to an RSU video detection integrated machine. Background Art

[0002] In recent years, the national expressway has developed rapidly, and the expressway network has gradually formed. With the implementation of the "Implementation Plan for Deepening the Reform of the Toll Road System and Canceling Provincial Boundary Toll Stations on Expressways" and the "Overall Technical Plan for Canceling Provincial Boundary Toll Stations on Expressways", networked electronic toll collection (ETC) technology has been greatly promoted and applied. Among them, phased array RSU, as the core key equipment of ETC technology, plays an important role in the application of networked electronic toll collection (ETC) technology. However, the traditional phased array RSU equipment and the bayonet camera are set up separately. The phased array RSU is only responsible for transactions with OBU and CPC cards, and the bayonet camera is only responsible for providing license plates, pictures, and video data. It can neither provide users with more precise and visual management, nor increase the difficulty of improving the picture and video evidence chain for the networked toll audit business of expressways. The RSU video detection all-in-one machine integrates the data of the phased array RSU with the video data and outputs visual information, which can better solve this problem. Utility Model Content

[0003] 1) Technical issues solved

[0004] Traditional phased array RSU equipment and bayonet cameras are set up separately. The phased array RSU is only responsible for transactions with OBU and CPC cards, and the bayonet camera is only responsible for providing license plates, pictures, and video data. RSU transaction data is separated from the vehicle passing video, and it is unable to provide RSU transaction area visualization, transaction process visualization, and transaction information visualization data. The RSU video detection all-in-one machine can realize RSU transaction area visualization, transaction process visualization, transaction information visualization, and provide relevant data for use by operation managers.

[0005] 2) Technical solution

[0006] An RSU video detection all-in-one machine, wherein a phased array RSU, a bayonet camera, and a fill light are fixedly installed on the front of the integrated structure, and a core controller is integrated inside. The phase includes a phased array RSU receiving / transmitting module and a wireless positioning processing module, which are responsible for the modulation / demodulation and communication of data between the OBU and CPC card, and the positioning of the OBU; the bayonet camera includes a capture unit and an image detection filter unit, which are responsible for providing video image data and license plate data; the fill light provides brightness compensation when the light is insufficient; the core controller includes a space synchronization unit and a data fusion processing unit, which are responsible for realizing the space-time synchronization of video image data, RSU calibration data, and RSU communication area, and fusing the data, and accurately judging the corresponding relationship between the OBU identified by the RSU and the ETC vehicle on the lane according to the RSU positioning coordinates combined with the virtual coil in the video image, so as to quickly and accurately complete the transaction.

[0007] In a further embodiment, a heat dissipation hole is opened on the back side of the core controller, a dust filter plate is fixedly installed on the inner wall of the heat dissipation hole, and a sealing cover plate is fixedly installed on the upper surface of the core controller.

[0008] In a further embodiment, the RSU video detection integrated machine can output video images with phased array RSU communication area and RSU real-time transaction information data (video images of editable ROI area), to achieve visualization of RSU transaction area and RSU transaction process; the RSU video detection integrated machine can also identify OBU reversed cards, large vehicles with small labels, drop-and-hook vehicles, and trailers suspected of evading fees through a fusion perception algorithm, and output alarm information and pictures and short videos with superimposed key characters to provide a chain of evidence for highway auditors.

[0009] III) Beneficial effects

[0010] Compared with the existing technology, the RSU video detection integrated machine can achieve three beneficial effects: visualization of RSU transaction area, visualization of transaction process, and visualization of transaction information data:

[0011] (1) Visualization of RSU transaction area: Based on the RSU positioning coordinates combined with the virtual coil in the video image, the positional relationship between the OBU in the transaction area and the ETC vehicle on the lane can be more accurately determined, and the transaction can be completed quickly and accurately, effectively solving the problems of adjacent lane interference and following vehicle interference. At the same time, the RSU transaction area coordinates calibrated by integrating video data can enable operation and maintenance personnel to perform data operation and maintenance efficiently and intuitively, and determine the cause of transaction abnormalities.

[0012] (2) Visualization of RSU transaction process and transaction information: After the RSU transaction data and video data are integrated, the built-in algorithm can be used to alarm and output pictures and short videos of vehicles suspected of evading tolls, such as OBU reversed cards, large vehicles with small labels, drop-off trailers, and trailers. This not only makes it easier for highway auditors to quickly locate vehicles that evade tolls, but also provides a more intuitive picture and video evidence chain. BRIEF DESCRIPTION OF THE DRAWINGS
