Embodiment 1

[0028] Such as figure 2 As shown, the method for solving adjacent lane signal interference for highway electronic toll collection in this embodiment includes: on a highway with multiple lanes, determine the effective communication area of ​​the roadside device RSU in a certain lane, and the effective communication area only covers The corresponding lane of the RSU does not intersect with the adjacent lane (step S101); generate a communication area judgment function f(x, y, z) according to the geometric shape of the effective communication area (step S102); send a broadcast signal to the highway, and Receive the reply information of the vehicle-mounted device OBU (step S103); generate the OBU position function OBU(x o ,y o ,z o ) (step S104); according to the OBU position function OBU(x o ,y o ,z o ) and the communication area determination function f (x, y, z) judge whether the OBU is in the effective communication area of ​​the corresponding lane of the RSU, if yes, the...

Embodiment 2

[0061] Such as Figure 11 As shown, the adjacent lane signal interference solution device for highway toll collection in this embodiment includes: a determination function storage unit 101, which is used to store the communication area determination function f generated according to the geometric shape of the effective communication area in the lane corresponding to the RSU (x, y, z); The signal sending and receiving unit 102 is used to send a broadcast signal to the highway, and receives the reply information of the vehicle-mounted device OBU; the position function generation unit 103 is used to generate the OBU position function OBU ( x o ,y o ,z o ); Communication establishment unit 104, for according to OBU position function OBU (x o ,y o ,z o ) and the communication area determination function f(x, y, z) determine whether the OBU is in the effective communication area of ​​the corresponding lane of the RSU, if yes, the RSU establishes a communication connection with ...

Embodiment 3

[0066] Such as Figure 13 As shown, the adjacent lane signal interference solution device for highway toll collection in this embodiment includes: an effective communication area setting unit 201, which is used to determine the location of the roadside device RSU in a certain lane on a highway with multiple lanes. Effective communication area, the effective communication area only covers the corresponding lane of the RSU and does not intersect with the adjacent lane; the determination function generation unit 202 is used to generate the communication area determination function f (x, y, z) according to the geometry of the effective communication area; The signal sending and receiving unit 203 is used to send a broadcast signal to the road, and receives the reply information of the vehicle-mounted device OBU; the position function generating unit 204 is used to generate the OBU position function OBU(x) according to the reply information of the OBU o ,y o ,z o ); Communication...

Abstract

The invention is a method and a device for solving signal interference of adjacent lanes used for road toll. The method comprises: determining an effective communication area of a road side unit (RSU) in a certain lane on a road which has a plurality of lanes, the effective communication area just covering the lane corresponding to the RSU and being not intersected with adjacent lanes; generating a communication area decision function f(x,y,z) according to a geometrical shape of the effective communication area; sending a broadcast signal to the road, receiving a reply message of a vehicle-mounted device (OBU); generating an OBU position function OBU(xo,yo,zo) according to the reply message of the OBU; determining whether the OBU is in the effective communication area of the corresponding lane of the RSU, if yes, the RSU and the OBU establishing communication connection, if no, the RSU refusing to communicate with the OBU. The method and the device are used to solve a problem of adjacent lane signal interference in an ETC (electronic toll collection) system.

Description

technical field [0001] The invention relates to the technical field of electronic toll collection of expressways, in particular to the roadside technology in the electronic toll collection system, in particular to a method and device for solving adjacent lane signal interference for highway toll collection. Background technique [0002] With the rapid development of the expressway electronic toll collection system (ETC: Electronic Toll Collection), the application of ETC continues to increase, and the performance requirements for the high efficiency and stability of the ETC system are also increasing. However, the main problem faced by the ETC system in the prior art is the problem of erroneous transactions caused by signal interference of adjacent lanes. [0003] Such as figure 1 Shown is the roadside unit (RSU) communication area diagram of three adjacent lanes in the existing ETC system. exist figure 1 Among them, three RSUs (10a, 10b, 10c) are installed on the frame 2...
