The method is limited by the vehicle running speed, the ambient illumination condition and the video image processing algorithm, so that missed triggering and false triggering are easily caused, and the capturing success rate of the snapshot subsystem and the license plate recognition success rate are influenced.
The transaction subsystem adopts a phased array Road Side Unit (RSU) which utilizes the spatial superposition relationship of signal phase and amplitude to strengthen or weaken the signal in a specific area, thereby achieving the purpose that the communication signal of the RSU antenna is concentrated in some areas. However, since the RSU cannot know the specific position of the On Board Unit (OBU for short), the RSU can only scan the trading area by turns, and this trading mode has blindness of signal scanning and cannot accurately guide the phased array to scan the area, which results in a lower trading success rate.
