System and method for carrying out toll authentication in intelligent transport system

Abstract

The invention provides a system and method for carrying out the toll authentication in an intelligent transport system. The system provided by the invention comprises a vehicle-mounted unit and an authentication label, wherein the vehicle-mounted unit is installed on a vehicle and used for executing fee reduction in a toll station; the authentication label is installed on the vehicle and arranged to be matched with the vehicle-mounted unit; the authentication label is used for executing the authentication with the vehicle-mounted unit by carrying out the wireless communication with the vehicle-mounted unit; the authentication label is used for determining whether the vehicle-mounted unit is matched with the authentication label or not; when the authentication result shows that the vehicle-mounted unit is matched with the authentication label, the vehicle-mounted unit is allowed to be continuously operated; and when the authentication result shows that the vehicle-mounted unit is not matched with the authentication label, the vehicle-mounted unit enters a failure state, thus the fee reduction can not be executed. The invention can be applied to the intelligent transport system, thereby preventing the vehicle-mounted unit from being stolen in an electronic toll collection scheme.

Description

technical field [0001] The present invention relates to how to implement the system and method of electronic non-stop toll collection (ETC) technology in the intelligent traffic system (ITS), especially to a method of preventing illegal use of on-board unit (OBU, On Board Unit) to pay by performing toll authentication systems and methods. Background technique [0002] In the existing intelligent transportation system, the Electronic Toll Collection (ETC) technology is realized by the On-Board Unit (OBU) fixedly installed on the vehicle and the Road Side Unit (RSU, Road Side Unit) located at the toll station. As one of the most critical components in the ETC electronic toll collection system, the OBU records important information such as the OBU identifier (the identifier is the unique serial number assigned to the OBU), user information, vehicle information, and user transaction passwords. When a vehicle equipped with OBU passes through the ETC toll station, the RSU at the ...

AI Technical Summary

Problems solved by technology

It can be seen that in order to ensure the reliability of the anti-dismantlement, the above two methods need to install more complex anti-dismantlement parts

[0005] 2. Low reliability

In this way, the OBU can be removed as a whole by lifting the OBU without separating the magnetic parts, and the anti-dismantlement position does not fail, so that the magnetic induction method does not play the role of anti-dismantlement

As for the mechanical anti-dismantlement method, there is a hidden danger that the failure of the mechanical button will lead to the failure of the anti-dismantlement

[0006] 3. The installation method is not flexible

When using these two anti-demolition methods, the OBU needs to choose an optimal angle during installation and mount it on the car windshield at this angle, and once installed, the OBU cannot be easily moved

This leads to great limitations in the installation position of the OBU, and it will affect the appearance and sight to a certain extent after being attached to the windshield.

At the same time, it also limits the expansion of OBU in function and application

[0007] To sum up, the existing OBU anti-dismantlement methods have the disadvantages of large space occupation, complex structure, limited installation methods and poor anti-dismantlement reliability.
