An urban traffic payment system based on block chain

Abstract

The invention provides an urban traffic payment system based on a block chain. Payment for urban transport tends to establish city-by-city standards, e.g. bus cards, each city has its own 'one-card' system. Although the 'one-card' system can be used in metro simultaneously, ferry, light rail and other traffic conditions, but in other cities the card's functionality is unusable. At the same time, all the 'one-card' systems are used in the way of updating data with the server end as the center, centralization easily leads to instability of the payment system, and user privacy information can notbe effectively protected. In view of this, the invention provides an urban traffic payment system based on block chain.

Description

technical field [0001] The invention relates to the field of urban traffic consumption, in particular to a blockchain-based urban traffic payment system. Background technique [0002] Looking back, the development of public transportation payment in my country has roughly gone through the era of physical tickets, the era of IC cards, and the era of mobile Internet that is developing. Before the 1990s, the means of payment for public transportation such as buses, trams, and subways in my country was basically limited to the purchase of physical tickets in cash, which were divided into one-time tickets and stored-value tickets (daily tickets, monthly tickets, and annual tickets). Until the mid-1990s, the public transportation IC card charging system appeared in Hangzhou, Shenzhen, Shanghai and other cities, and since then it has sprung up in large and medium-sized cities across the country. Switched card system. Soon various types of IC cards became the mainstream of public ...

AI Technical Summary

Problems solved by technology

[0004] In some cities, subway tickets can only be purchased in cash of RMB 5 or RMB 10. Because of the damage of the banknotes, the banknotes cannot be used, which affects the efficiency of ticket purchases.

[0005] Second, it is difficult for IC cards to communicate with each other

[0006] In the era of IC cards, hundreds of cities across the country established their own independent bus IC card toll systems, lacking unified standards and unified management regulations, which caused a big dilemma for future interconnection efforts. There are also efforts such as the national city card interconnection project, but there are also defects in the scattered distribution of platform cities and weak regional continuity. In most regions of the country, especially small and medium-sized cities, the interconnection of public transportation payment between cities is realized. Interoperability is still a luxury. In the mobile Internet era, this problem has been expanded with the emergence of various new payment methods. It can be summed up in three words-fragmentation

[0007] Third, the operation and management of the IC card charging system in many cities is backward

For example, the patent application number of the existing technology is: 201720498058.2 mentioned in the patent application that the rapid increase in population and the rapid increase in vehicle ownership have a great impact on urban public transport travel and urban congestion control measures

At present, the mainstream means of payment for buses is cash and bus cards (existing technology), causing citizens to get on the bus slowly or unable to travel because of forgetting to bring their bus cards, which has seriously affected the efficiency of urban public transport operations. Most of the vehicle-level dedicated Beidou / GPS positioning systems are not installed on the road, and the traffic department cannot grasp the vehicle operation status in real time, which has brought a great impact on the overall dispatching work. In order to solve this problem, this prior art document adopts: 1. A bus transaction terminal device with a two-dimensional code payment function, comprising a main control chip module, a communication module, an NFC module, a two-dimensional code module, a positioning module, a card module, a liquid crystal module, a voice broadcast module, a UART module, a storage module and a power supply module, the communication module, NFC module, two-dimensional code module, positioning module, card module, liquid crystal module, storage module and power supply module are all connected to the main control chip module, wherein the main control chip module is used to control each Data communication and operation of the module; the communication module is used for data exchange between the device terminal and the database platform and sending positioning data; the NFC module is used for data communication with the mobile smart device during payment operation; the two-dimensional code module is used for providing two-dimensional code The data is sent to the mobile smart device to scan the code to pay; the positioning module is used to locate the location of the bus in real time, and send the real-time location information to the background management system of the transportation department; the card module is used to pay by swiping the card; the LCD module is used to display the user's consumption amount , the balance of the user's traffic card, payment method, type of ticket inspection, number of card swipes, positioning status, communication status, and real-time Beijing time; the voice broadcast module is used to play the user's consumption amount and card swiping type; the UART module is used to connect to a computer or Smart devices, and upgrade the local firmware; the storage module is used to store the user's consumption information, traffic card balance information and blacklist information, and connect to the bus management system through the communication module

However, through the above systems, the entire payment and recording process needs to rely on the existence of a centralized server. The operation of the urban public transport system still relies on the server, and there is still a risk of system failure caused by server crashes. At the same time, the existing passive scanning code and NFC bus payment lack uniformity. Supervision, lack of confidentiality in track management
