Expressway pass card and communication method thereof

Abstract

The invention provides a highway pass card and a communication method thereof. The highway pass card comprises a 5.8GHz communication module, a 13.56MHz communication module, an NB-IoT module, a control module and a power supply module. The highway pass card integrates the functions of accurate path recording, toll payment, real-time positioning and card locking on the basis of functions of an existing pass composite card, realizes collection and uploading of vehicle information and information in the pass card and receiving of a background instruction by integrating the 5.8GHz communication module, the 13.56MHz communication module, the NB-IoT module and the control module, solves the problem of high complexity in toll escape identification and judgment, can issue an instruction for cardlocking operation in real time according to the judgment result to prevent a vehicle from passing. Based on active characteristics of the composite pass card, an ETC application is established in thecomposite pass card, and the instruction is issued through the NB-IoT module; and recharging of an ETC user card electronic wallet can be realized without a card reader.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a highway pass card and a communication method thereof. Background technique [0002] In recent years, my country's expressway has experienced rapid development, the expressway network has been continuously extended and the toll area has been continuously expanded, and the national network has gradually been realized. At present, expressways have basically realized the "one card" in all provinces. Vehicles only need to pass through toll stations when entering and exiting expressways. There are no other toll stations during driving. Pay the toll on the highway. But for a long time, my country's expressways have implemented a management system that demarcates boundaries by provinces and collects fees by provinces. Due to the different toll standards of each province, the toll card is not compatible, and there may be multiple driving paths between the exit and t...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide a highway pass card and its communication method, aiming to solve the problem that the existing ETC card cannot realize real-time positioning and path identification, and cannot load and write the card in real time, so as to realize the path identification and blackout of the pass card. List real-time lock card function, and can carry out real-time transfer and write card without a card reader
