Embodiment 1

[0028] This embodiment is based on the fusion of radio frequency and IC card data, as shown in Figure 1. The radio frequency signal receiving antenna is connected to the signal receiving end of the MAXIM7033 radio frequency module through a matching circuit composed of a series capacitor C7 and an inductor L2. The radio frequency module is surrounded by conventional peripheral circuits, and its digital signal output interface DATAOUT is connected to the data input interface of the PIC16F688 microprocessor. 1 card, dual-interface mifare desfire card or dual-interface mifare pro card) the corresponding ports of chip J2 are connected.

Embodiment 2

[0030] The basic circuit principle of the expressway multifunctional access card of this embodiment is the same as that of Embodiment 1, the difference is as shown in Figure 2, the radio frequency signal is connected to the signal receiving end of the nRF905 radio frequency module. The radio frequency module is surrounded by conventional peripheral circuits, and its digital signal output interface DATAOUT is connected to the data input interface of the MSP430 microprocessor. 1 card, dual-interface mifare desfire card or dual-interface mifare pro card) the corresponding ports of chip J2 are connected.

[0031] After the radio frequency signal is received by the antenna in the access card, it passes through the matching circuit and enters the radio frequency module. The MAXIM7033 chip\nRF905 chip used in this circuit diagram can be replaced by other chips of the same type. After the radio frequency signal is processed by amplification, frequency conversion, demodulation, etc., ...

Abstract

The invention involves highway-use integrated access card based on wireless RF and data integration, also involves its application method in the highway path identification system. The highway-use card contains RF module and IC chips. The signal receiver of RF module connects to the receiving antenna through matching circuit, in addition, contains microprocessors, the digital signal output interface of RF module connects to the data input interface of the microprocessor. The communication port of microprocessor includes dual-interface mifare 1 card, and dual-interface mifare desfire and dual-interface mifare pro card which connects to the corresponding port in IC card. The invention integrates the radio frequency identification technology, IC card (IC) and the data fusion technology to reasonably solve various defects in the existing technologies without the need to increase construction costs, which can greatly reduce the cost of the investment system and effectively be used.

Description

technical field [0001] The invention relates to an expressway access card, in particular to a multifunctional expressway access card based on the fusion of radio frequency and IC card data, and at the same time, the invention also relates to an application method of the access card in an expressway path identification system. Background technique [0002] In the expressway network toll collection environment, the current toll collection method is: the vehicle receives a pass card at the entrance toll station of the expressway, and calculates the toll payable at the exit toll station according to the entrance station information of the pass card. Expressway pass cards generally use IC cards as pass tickets for recording entrances, which have the advantages of safety, reliability, simple operation, high efficiency, and not easy to be damaged. At present, domestic expressways usually use mifare 1 cards or mifare desfire cards. The number of mifare 1 Accounted for more than 90%....
