Subway ticket checking terminal based on low-power-consumption bluetooth and two-dimensional code scanning

Abstract

The invention provides a subway ticket checking terminal based on a low-power-consumption bluetooth and two-dimensional code scanning. The terminal is composed of a bluetooth module, a two-dimensional code scanning module, a central processing unit module, a storage module, a network module, an encryption and decryption module, and a serial port module. The bluetooth module is used for broadcasting a data packet with a low-power-consumption bluetooth 4.0 or above version; the two-dimensional code scanning module is used for scanning a two-dimensional code, wherein the code system of the two-dimensional code is PDF417; the encryption and decryption module is a PSAM card; and the serial port module is used for invoking an industrial personal computer device of external equipment to open a turnstile of the subway. According to the invention, on the basis of combination of the low-power-consumption bluetooth technology and two-dimensional code scanning, rapid ticket checking by the subway ticket checking terminal is realized; information transmission safety and stability are improved; the user experience degree is high; and the market prospect of popularization and application is broad.

Description

technical field [0001] The invention relates to the field of ticket checking for public transportation, in particular to a subway ticket checking terminal based on low-power bluetooth and two-dimensional code scanning. Background technique [0002] Compared with other means of transportation in the city, in addition to avoiding urban ground congestion and making full use of space, the subway has many advantages. First, the transportation capacity is large. The transportation capacity of the subway is 7-10 times larger than that of the ground bus. The second is that the speed is fast, and the subway train travels at a high speed in the underground tunnel, and the speed of travel can exceed 100 kilometers per hour. At present, the subway passenger transport departments in various cities in China have established relatively complete ticket purchase and ticket inspection systems, and generally use non-contact IC cards as the carrier of ticket cards. The process is relatively sl...
