Two-stage treatment free stream electronic toll collection lane system and method

Abstract

The invention discloses a two-stage treatment free stream electronic toll collection lane system and method. The system comprises a main control machine and a road side read-write device which are connected, wherein the road side read-write device comprises a microwave antenna which can project an awaking communication region and a transaction communication region on a lane, as well as an antenna controller; the microwave antenna and the antenna controller are connected. The method comprises the following steps of: in the awaking communication region, the microwave antenna only performs awaking treatment operation on vehicle-mounted electronic tags in the communication region, and does not undertake the transaction treatment operation; in the transaction communication region, besides direct transaction treatment operation on the awakened electronic tags in the communication region, the microwave antenna performs awakening and transaction treatment operation on the un-awakened electronic tags. The electronic toll collection lane system provided by the invention can increase the vehicle restriction speed value further, so that the electronic toll collection can be applied to a free stream environment with high vehicle speed.

Description

technical field [0001] The invention relates to an electronic non-stop charging lane system, in particular to a free-flow electronic non-stop charging lane system and method with two-stage processing, belonging to the field of vehicle non-stop charging. Background technique [0002] At present, in the application field of Electric Toll Collection (ETC) in my country's highways, due to the influence of the operating environment, the ETC lanes of various toll stations are often equipped with automatic barriers, using a non-free flow lane traffic mode. With the in-depth development of highway network toll collection and the continuous improvement of users' requirements for ETC services, free-flow ETC lanes with better traffic experience and higher traffic handling capacity will inevitably become an important trend in the field of highway toll collection, especially with the After the toll collection of the highway network, the solution to the ambiguous path problem and the cons...

[0004] Moreover, in order to complete the above-mentioned processing operation of the microwave antenna on the electronic tag, the corresponding ETC vehicle must be within the range of the communication area where the microwave antenna is projected on the lane. Assuming that the length of the communication area is L, the time required for the completion of the above two links is combined. , then the speed limit Vmax ≤ L / (t 唤醒时间 +t 交易时间 ), if the vehicle speed exceeds the speed limit Vmax, it means that the vehicle will not have enough time to complete the electronic tag wake-up and transaction processing operations necessary for ETC vehicle transactions in this given communication area, resulting in the failure of vehicle transactions fail

[0005] The invention patent with the Chinese patent number CN200510101197.9 discloses "a dual-communication area electronic non-stop toll lane system and its realization method" and the utility model patent with the Chinese patent number CN200520067262.6 discloses "a dual-communication area electronic Although the above-mentioned method uses two sets of microwave antennas with different emission angles to form two communication areas, the wake-up and transaction operations of the vehicle-mounted electronic tags are all arranged in the same antenna communication area for processing. For this reason, this method also has the aforementioned problems, and the speed of the vehicle will be greatly limited due to the wake-up of the electronic tag and the transaction time
