Subway taking off-line processing system and method based on off-line two-dimensional code ticket-card

Abstract

The invention discloses a subway taking off-line processing system and method based on an off-line two-dimensional code ticket-card. The subway taking off-line processing system based on the off-linetwo-dimensional code ticket-card comprises an APP background, a clearing server, gate machine terminals located at different subway stations and client APP of different users; wherein the clearing server is connected with the APP background and each gate machine terminal separately, and the APP background is connected with each APP client separately. The subway taking off-line processing method based on the off-line two-dimensional code ticket-card comprises the following steps of an authorized signature data generation and update step, an authorized signature data obtaining step, a two-dimensional code ticket-card generation step, a two-dimensional code ticket-card showing step, a two-dimensional code ticket-card checking step, an import and export information obtaining step, a transaction data matching step and a transaction data settlement and pushing step. The subway taking off-line processing system and method based on the off-line two-dimensional code ticket-card supports the off-line code generation of the APP clients and the off-line checking of the gate machine terminals, therefore, the generation and checking of the two-dimensional code ticket-card is not restricted by the communication network, which brings great convenience for subway taking of users.

Description

technical field [0001] The present invention relates to subway rides, in particular to an offline processing method of a subway ride offline processing system based on an offline two-dimensional code ticket. Background technique [0002] The subway is a fast and large-capacity urban rail transit mode that is gradually developed along the surface railway system, and its lines are usually laid in underground tunnels. With the development of the current society, the subway has become an indispensable means of transportation in modern society. The operation of the subway has slowed down traffic congestion. As a means of transportation, it is also the fastest one without congestion. [0003] At present, the subway mainly purchases temporary tickets at stations or long-term radio frequency cards handled by users themselves to control gate passages and settle fees when entering and leaving stations; however, when purchasing temporary tickets at stations, they often queue up, wastin...

AI Technical Summary

Problems solved by technology

[0003] At present, the subway mainly purchases temporary tickets at stations or long-term radio frequency cards handled by users themselves to control gate passages and settle fees when entering and leaving stations; however, when purchasing temporary tickets at stations, they often queue up, wasting a lot of time for passengers Compared with purchasing temporary tickets, the way of using radio frequency card to swipe the card to enter and exit the station has certain convenience. However, when users take the bus, they often forget to bring the radio frequency card, and the radio frequency card is easy to lose, which is why Passengers have a lot of inconvenience in subway rides

[0004] In today's society, mobile smart devices (mobile phones, APPs, etc.) have gradually become indispensable items in people's lives. Combining smart mobile devices for subway ride verification can not only avoid the problem of buying tickets by train, but also avoid the problem of radio frequency cards. For the problem of lost, the method of payment for subway rides through QR codes has gradually begun to be used. However, when using QR codes for rides, the station for entering and leaving the station is often set through the ride APP installed on the mobile phone. , initiate a ride application to the background server, and the background server generates a two-dimensional code, which is sent to the user's ride APP and the gate of the corresponding station. The code ride method requires that the user's ride APP and the gate terminal of the site must maintain a connection with the background server; when the signal of the user's mobile phone is weak, or the gate terminal network is interrupted, the two-dimensional code ride verification cannot be performed, and the user There is still inconvenience in driving
