Abstract

The invention discloses a vehicle-mounted unit applied to a path identification system and a safe method of the vehicle-mounted unit. The path identification system comprises the vehicle-mounted unit composed of an electronic label, a roadside unit composed of a roadside identification station and a desktop unit composed of a lane card reader and a service subsystem; the vehicle-mounted unit comprises an Msp430 microcontroller module, a PSAM safety certificate module, a GBM-DD103 positioning time service module, a CC1101 RF module, antennas and a FLASH storage module; and the GBM-DD103 positioning time service module and the PSAM safety certificate module configured in the vehicle-mounted unit provide positioning time-service and encryption functions respectively. A visitor can authorized via the encryption function, invalid access is prevented, and the legality and validity of a path identification can be determined via the positioning time-service function; and thus, the safety of the whole system is improved.

Description

technical field [0001] The invention relates to a path recognition system in the field of intelligent transportation, in particular to an application [0002] On-board unit and safety method for path recognition system. Background technique [0003] With the rapid development of my country's economy, the construction of expressways tends to be intelligent, and ETC electronic toll collection technology is a typical representative of the application field of intelligent transportation. Due to the complexity of my country's expressway system, some provinces often adopt the operation mode of combining national construction and private investment, and distributing income in proportion. With the continuous construction of expressways, the road network becomes more and more complex. There are often many different paths from an entrance to an exit, and these different paths may belong to different investors. The early toll system could not judge the path of vehicles, so the benefi...
