Front-mounted electronic toll collection (ETC) on board unit online publication system and method

Abstract

The invention relates to the technical field of electronic toll collection (ETC), in particular to a front-mounted ETC on board unit online publication system and a front-mounted ETC on board unit online publication method. The system consists of an on board unit, a mobile publication device, a remote server and an encryptor, wherein the mobile publication device is used for awakening the on board unit, and performing dedicated short range communication (DSRC) with the on board unit by using publication data acquired in real time from the remote server and key data calculated by the encryptor through a wireless communication network such as a third-generation (3G) wireless communication network; and the remote server is used for performing publication operation such as initialization, personalization and tamper activation on the front-mounted on board unit through a communication channel of the mobile publication device. According to the system and the method provided by the embodiment of the invention, the publication data can be acquired from the remote server in real time, the on board unit can be updated in real time, the respective storage of keys for operating the on board unit in each piece of publication equipment is avoided, and the security of a key medium and convenience for a publication service are improved.

Description

technical field [0001] The present invention relates to the technical field of Electronic Toll Collection (ETC), in particular, the present invention relates to a front-mounted ETC vehicle-mounted electronic tag online issuing system and method.
