Embodiment Construction

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0047] The invention provides a transaction method for eliminating adjacent channel interference, which is applied to such as figure 1 The multi-lane system in the same direction is shown, wherein each lane is correspondingly provided with a roadside unit (Road-SideUnits, RSU) for wireless communication with an onboard unit (OnboardUnit, OBU), and the coverage of multiple roadside units is Overlapping area 2 and stable trading area 1 excluding overlapping area...

Abstract

The invention discloses a transaction method of eliminating adjacent lane interference, applied to an equidirectional multiple lane system. Each lane is correspondingly provided with a road-side unit (RSU) used for wireless communication with an on board unit (OBU); the coverage areas of a plurality of RSUs share overlapped parts. The method comprises: synchronizing the time sequence of the plurality of RSUs, and configuring the emission parameters of the plurality of RSUs to be same; according to the time sequence, the plurality of RSUs simultaneously issuing transaction commands, the contents of transaction commands being set according to the current transaction step of each RSU; and the RSU receiving the feedback signal of the OBU completing the current transaction step with the OBU. According to the invention, the OBU can not transact in the overlapped parts of the RSUs, so that the RSU of a lane can not transact with the OBU of a nearby lane, thereby completely eliminating lane interference.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a transaction method for eliminating interference from adjacent roads, a roadside unit and a multi-lane system in the same direction. Background technique [0002] In the application of multi-lane in the same direction of highway and parking lot ETC, in order to achieve no blind spots in the communication area, so as not to affect the transaction effect, it is often impossible to ensure that the signal of the roadside unit only covers the area of ​​​​the lane, and will not cover the area next to it. area. In the prior art, in order to seamlessly cover the communication area of ​​the lane, the signal of the roadside unit generally covers a little bit of the lane next to it. Although the coverage of the communication area can be reduced by reducing the transmission power of the roadside unit, if the power is reduced, the effect of the transaction between the roadside unit...
