Abstract

The invention discloses a method for controlling an antenna wave beam to point to a moving vehicle, an antenna and a no-stop parking charge system, which relate to the technical field of antenna and are designed for better ensuring the passing speed of the vehicle and better avoiding the following interference. The method for controlling the antenna wave beam to point to the moving vehicle comprises the following steps: detecting the position of the moving vehicle in the process of running; adjusting the pointing angle of the antenna wave beam according to the detected position of the moving vehicle to control the antenna wave beam to follow and point to the moving vehicle. The antenna comprises a wave beam controller and a phased antenna array, wherein the wave beam controller is used for determining a phase-shifting angle of each basic antenna array in a phased antenna array according to the position of the moving vehicle, and generating a phase-shifting control code according to the phase-shifting angle; the phased antenna array is used for utilizing the phase-shifting control code to adjust the pointing angle of the antenna wave beam in the phased antenna array so as to control the antenna wave beam to follow and point to the moving vehicle. The invention can be used for the no-stop electronic toll collection.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a method for directing an antenna beam to a moving vehicle, an antenna and a non-stop charging system. Background technique [0002] The Electronic Toll Collection system (ETC system for short) can use the dedicated short-range communication technology (Dedicated Short Range Communication, DSRC for short) to complete the roadside unit (Roadside Unit, RSU) and on-board unit (On Board Unit, OBU) The two-way communication between the two-way, security authentication and consumption deduction through wireless means, to realize non-stop toll collection, greatly speed up the vehicle traffic, reduce the congestion at the toll ramp, and improve the transport capacity of the road. [0003] The RSU of the non-stop charging system is generally erected on the gantry above the ramp of the toll station. The vehicle equipped with the OBU passes the toll station at a normal speed. Both the RSU ...
