Embodiment Construction

[0037] Embodiment 1 of the present invention proposes a rail transit national secret reader, such as figure 1 shown, including:

[0038] The main control module 10 is used to call the program and data in the code storage module 60, run the transferred program and data through the SDRAM memory 150, and then send read and write commands according to preset instructions. The main control module 10 in the present invention Can be IMX6Q application processor.

[0039] HDMI (High Definition Multimedia, high-definition multimedia interface) display module 20, is connected with main control module 10, is used for communicating with external display device, and HDMI display module is connected with external display device interface such as figure 2 shown. HDMI can provide up to 5Gbps data transmission bandwidth, transmit uncompressed audio signals and high-resolution video signals; at the same time, there is no need for digital / analog or analog / digital conversion before signal trans...

Abstract

The invention discloses a rail transit national password reader-writer, which comprises a main control module for calling and operating programs and data and sending out a read-write command accordingto a preset instruction; a display module connected with the main control module and used for communicating with external display equipment; a SATA module connected with the main control module and used for carrying out data transmission; an SB module connected with the main control module and used for being connected with external USB equipment; an RGMII module connected with the main control module and used for realizing network access; a code storage module connected with the main control module and used for storing codes and data; a national password security module connected with the main control module and used for encrypting and decrypting data; and a radio frequency module connected with the main control module and used for identifying and reading the radio frequency card. In theinvention, the national secret chip is used for replacing an original international chip to encrypt and decrypt the data, so that the data processing security is greatly protected in the ticket selling and checking system.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a rail transit national secret reader / writer. Background technique [0002] With the increase of subway lines, the importance of rail transit is becoming more and more prominent. In the rail transit fare collection system, it includes a ticket card data processing and data transmission process from the ticket card to the reader, and from the reader to the terminal equipment. At present, the reader / writer used in the fare collection system encrypts and decrypts the ticket card data through DES (symmetric encryption algorithm). The specific process is to ensure the legitimacy of the transaction through a two-way authentication mechanism between the reader and the non-contact IC card. The two-way authentication method uses the security mechanism built in the SAM, using the combination of DES encryption algorithm and random numbers, and the data communication conforms to ISO979...
