Vehicle management system based on optical communication

Abstract

The invention relates to a vehicle management system based on optical communication. The vehicle management system based on the optical communication comprises a path information emitting module, a vehicle-mounted module and an optical signal receiving module, wherein the path information emitting module is used for emitting signals with path identification information, the vehicle-mounted module comprises a signal receiving unit and an optical signal emitting unit, the signal receiving unit is used for receiving the path identification information and transmitting the path identification information to the optical signal emitting unit, the optical signal emitting unit is used for emitting vehicle identification information and the path identification information, and the optical signal receiving module is used for reading the vehicle identification information and the path identification information. By means of the cooperation of the modules, the vehicle management system based on the optical communication solves the problem that an existing toll collection system cannot recognize a plurality of different paths, improves traffic efficiency of road network, is free of electromagnetic disturbance, and reduces damage of radiofrequency radiation to the human body.

Description

technical field [0001] The invention relates to a vehicle management system, in particular to a vehicle management system based on optical communication. Background technique [0002] Network charging is the general trend of road network charging in various regions at present. At present, most regions have implemented the road network charging system based on IC cards. Due to the inconvenience of the IC card charging system, the long-distance RFID automatic charging system came into being. The RFID automatic toll collection system is realized through the cooperation of the RFID reader and the RFID card. At that time, the reader receives the radio frequency signal coupled back from the RFID card for identification and communication. The frequency used by the existing road network charging system is usually the same as that used by communication tools such as mobile phones, and therefore, sometimes interferes with existing mobile phone signals. The communication distance is ...
