Intelligent ETC lane toll collection system and intelligent ETC lane toll collection method based on phased array

Abstract

The embodiments of the invention disclose an intelligent ETC lane toll collection system and an intelligent ETC lane toll collection method based on a phased array. The system comprises at least two vehicle queue detection sensors, main reading and writing equipment, and a main control machine. The main control machine acquires vehicle position information fed back by the vehicle queue detection sensors and toll collection information and tag position information identified by a phased array antenna in the main reading and writing equipment, and constructs vehicle queue model information. When the vehicle position information of a current vehicle under transaction is consistent with the tag position information, a billing transaction is conducted. If the billing transaction status indicates that transaction fails, backup reading and writing equipment is started for billing transaction. If the billing transaction status indicates that transaction succeeds, the main control machine opens a barrier gate to release the vehicle, and the vehicle queue model information is updated. Through the technical scheme of the invention, the transaction efficiency of the main identification area, the processing efficiency of vehicle passing and the reliability of billing transaction are improved, and the flexibility of system construction is increased.

Description

technical field [0001] Embodiments of the present invention relate to lane toll collection technology, in particular to a phased array-based intelligent ETC lane toll collection system and method. Background technique [0002] Due to my country's special national conditions, congestion is a major shackle in the development of my country's transportation. As one of the most advanced road and bridge toll methods in the world, the mission of the Electronic Toll Collection (ETC) system is to use intelligent technology to change this situation. . Through the microwave communication between the on board unit (OBU) installed on the inside of the front windshield of the vehicle and the roadside antenna unit erected on the side of the ETC lane of the toll station, information is exchanged during the driving process of the vehicle. Thereby reaching the purpose that the vehicle can pay the road and bridge toll without stopping when passing through the road and bridge toll station, and ...

Problems solved by technology

However, when the system is switched to work with the near-field antenna, the far-field antenna is also required to be in an open state, causing the OBU of the far-field vehicle to be activated by the far-field antenna, and the activated OBU is easy to trade with the working near-field antenna, thereby allowing the vehicle to pass. Untraded vehicles in the near area affect the reliability of the transaction. At the same time, the radiation unit of the antenna in the far area interferes with the work of the antenna in the near area, resulting in low identification accuracy of the antenna.
