Embodiment Construction

[0048] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0049] Such as figure 1 Shown, a kind of expressway billing method based on GNSS equipment, expressway billing method comprises:

[0050] S1. When the vehicle enters the highway entrance, the entrance RSU activates the Bluetooth module of the OBU and turns on the GNSS device;

[0051] Step S1 includes:

[0052] When the vehicle enters the highway entrance, the entrance RSU sends a DSRC signal to activate the Bluetooth module of the OBU, and the OBU communicates with the GNSS device through the Bluetooth module, and the GNSS device starts the application for obtaining GNSS information.

[0053] S2. When the vehicle is driving normally on the expressway, the OBU randomly obtains the current GNSS information of the GNSS device, encrypts it and uploads it to the billing background through the GNSS device;

[0054] Step S2 includes:

[0...

Abstract

The invention discloses an expressway charging method and system based on GNSS equipment, and the method comprises the steps: S1, an entrance RSU activates a Bluetooth module of an OBU when a vehicleenters the entrance of an expressway, and GNSS equipment is started; S2, when the vehicle runs normally on the expressway, the OBU randomly acquires current GNSS information of GNSS equipment, encrypts the current GNSS information and uploads the encrypted current GNSS information to a charging background through the GNSS equipment; S3, when the vehicle passes through an ETC portal frame, the OBUobtains the GNSS information of the ETC portal frame and the current GNSS information of the GNSS equipment, and the GNSS information and the current GNSS information are encrypted and then uploaded to a charging background through the GNSS equipment; and S4, when the vehicle drives out of the exit of the expressway, the exit RSU acquires the information of the OBU and uploads the information to the charging background, and the charging background acquires the data uploaded by the GNSS equipment according to the information of the OBU and determines whether the GNSS equipment is credible or not according to the data uploaded by the GNSS equipment. The charging center confirms the credibility of the GNSS equipment according to the data uploaded by the GNSS equipment, thereby confirming thecredibility of the GNSS information of the GNSS equipment, and guaranteeing the charging accuracy and safety.

Description

technical field [0001] The invention relates to the field of expressway charging, in particular to a method and system for expressway charging based on GNSS equipment. Background technique [0002] It is very important to cancel provincial toll stations and accelerate the promotion of ETC. Under the guidance of national policies, with the increase of preferential policies of issuing agencies, it can be expected that by the end of 2019, the installation rate of ETC on-board equipment in registered cars will reach 80%. [0003] According to the "Overall Technical Plan for Canceling Provincial Boundary Toll Stations on Expressways", the ETC vehicle charging method is adjusted to free flow charging, the existing entry / exit toll stations are retained, and ETC gantry is built along the section of the expressway within the expressway road network. Through ETC technology, the tolls of passing vehicles are billed in sections, so that they can pass quickly without stopping. The ETC m...
