Abstract

The invention discloses a desktop unit and a safety method applied to a path identification system. A lane card reader in the desktop unit comprises a Cortex-A7 micro-processor module, a PSAM safety authentication module, a storage unit, a CC1101 radio-frequency module and an antenna; and a service sub-system comprises a communication module, a database module and a safety processing module. The lane card reader in the desktop unit is equipped with the PSAM safety authentication module; valid path identification information, coordinate fitting information and the like are stored in a database of the service sub-system; therefore, validity judgement of a vehicular unit is realized; validity judgement of a path identifier in the vehicular unit is realized; effective judgement of the path identifier in the vehicular unit is realized; and the safety of the system is improved through a series of safety interaction rules with other equipment in the system.

Description

technical field [0001] The invention relates to a path identification system in the field of intelligent transportation, in particular to a desktop unit and a safety method applied to the path identification system. Background technique [0002] 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 benefits co...
