Abstract

The invention discloses a transaction method for eliminating the interference of adjacent lanes, which is applied to a multi-lane system in the same direction, wherein each lane is correspondingly provided with a roadside unit for wireless communication with a vehicle-mounted unit, and multiple roadside units cover There is an overlapping area in the range, and the method includes synchronizing the timing of multiple roadside units, and setting the transmission parameters of multiple roadside units to be the same; according to the timing, multiple roadside units send transactions at the same time command, the content of the transaction command is set according to the current transaction steps of each roadside unit itself; the roadside unit that receives the feedback signal from the vehicle-mounted unit completes the current transaction steps with the vehicle-mounted unit. Adopting the present invention can ensure that the vehicle-mounted unit cannot be traded in the overlapping area of ​​the roadside unit, and further ensures that the roadside unit of the current lane cannot trade with the vehicle-mounted unit of the adjacent lane, thereby completely eliminating the interference of the adjacent road.

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...
