Subway lockage payment method and system based on digital currency

Abstract

The invention provides a subway lockage payment method and system based on digital currency, and relates to the field of subway lockage. An intelligent terminal generates first communication data during entering ticket checking and passing-gate and encrypts the first communication data to generate an entering-gate identifier, then the entering-gate identifier is obtained at an exiting-gate in a way that an intelligent terminal communicates with a gate AFC ticket card processing unit, and the AFC ticket card processing unit generates second communication data according to an exit identifier andthe first communication data, records the second communication data locally and sends the second communication data to a subway gate upper computer SLE module through a serial port; and after the SLEmodule receives the second communication data and judges a flag bit in the second communication data, the SLE module executes a gate opening action. Since bidirectional concurrent data stream transmission with background online transactions such as Unionpay is not needed, the situations of slow response, high delay and system stability failure of a gate passing machine do not exist when the userpasses through the gate, so that the user can smoothly pass through a subway payment gate in an extremely short time.

Description

technical field [0001] The invention relates to the field of subway gate passage, in particular to a payment method and system for subway gate passage based on digital currency. Background technique [0002] With the development of infrastructure, the public transportation system represented by the subway is growing stronger and stronger, and the electronic data flow of the subway payment gate system has increased significantly. The payment gate method represented by QR code scanning has many advantages such as convenience, quickness, contactless safety and sanitation. But on the other hand, a large number of people flow puts pressure on the subway payment gate system, especially during the rush hour. Background online transactions have slow response, high delay (50-200ms delay), and sometimes even system stability failures, which affect the smooth completion of payment by gate passers, thereby affecting the efficiency of the entire gate flow of people. [0003] In order t...

AI Technical Summary

Problems solved by technology

However, these measures have not fundamentally solved the system collapse of the subway gate system during the commuting peak, and the adjustment of the subway arrival control system is highly complicated, which reduces the transportation efficiency of the subway

Moreover, the existing subway payment gate system still has problems such as difficulty in checking the user's payment account after payment, low security and privacy, etc.
