Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, in the present embodiment, a roadside unit 1 includes a main control module 11, an encryption/decryption module 16, a radio frequency module 12, a communication module 13, where the encryption/decryption module 16, the radio frequency module 12, and the communication module 13 are respectively connected to the main control module 11, and further includes an identity authentication module 14 and a switch module 15, where the switch module 15 and the identity authentication module 14 are respectively connected to the main control module 11;

the identity authentication module 14 is used for authenticating identity information of the roadside unit 1 operator;

the main control module 11 is configured to obtain identity information and judge operation authority, and send a confirmation signal to the switch module 15 when the operation authority is available;

the switch module 15 is configured to turn on the operation terminal of the roadside unit 1 upon receiving the confirmation signal.

In the embodiment of the utility model, the identity authentication module 14 is arranged for authenticating the identity information of the roadside unit 1 operator, the master control module 11 judges the identity authority of the operator, and the operation end of the roadside unit 1 can be opened only under the condition that the authority passes. Further, the safety of the roadside unit 1 is ensured, and only an operator having authority is allowed to operate.

Specifically, the encryption and decryption module 16 is a security module for verifying the validity of the user card and protecting the deduction behavior of the terminal equipment, and the encryption and decryption module 16 is an important component of the control system of the road side unit 1.
