【摘要】：随着微电子技术及电子应用技术的迅猛发展,除了传统的逻辑加密卡、CPU卡,相继出现了多功能USIM卡、Apple Pay、Samsung Pay、小米Pay、扫码支付等多种新型的支付方式。"一卡通"这个十几年前还较为新鲜的名词,随着互联网+理念的形成,"卡"这个载体介质也已发生实质改变。借助手机的NFC功能,通过发卡机构或中国银联制定的统一的技术规范及结算规则,人们的移动支付体验不断改善,有效地推动了国内移动支付产业的发展和移动支付多场景应用生态圈的构建。公交刷卡机作为公交车上的重要电气设备,对提高出行效率和便捷性作用巨大,在互联网+对传统行业的冲击下,公交刷卡机升级换代势在必行,智能化的车载消费终端应运而生。如何提供一款支持多种移动支付方式的智能车载消费终端是一个非常有意义的课题。本课题的研究内容围绕智能车载消费终端的软硬件设计与实现展开,通过需求分析,论证了采用Cortex-M3 ARM处理器和FreeRTOS操作系统作为整体软硬件方案的可行性,以此为基础,重点研究了电源电路设计、天线参数匹配、无线数据采集、免签免密支付等在开发过程中涉及的关键技术。本文首先对智能车载终端研究过程中使用的重要技术进行介绍,然后根据调研确定的产品需求,对整体硬件方案、各硬件功能模块、软件整体框架进行了综述,接着对重要硬件模块、软件任务进行详细介绍,然后对开发及使用过程中碰到的问题进行了细致地剖析和总结。课题完成的主要工作包括逻辑加密卡、CPU卡、多功能USIM卡、小米支付、银联闪付卡(免签免密)、二维码支付的消费功能,余额及交易记录查询功能,交易记录的远程采集功能等,经过黑盒白盒测试及市场试用,最终实现了设计目标。
[Abstract]:With the rapid development of microelectronics technology and electronic application technology, besides the traditional logic encryption card and CPU card, there are various new payment ways, such as multi-function USIM card, Apple Pay, Samsung Pay, millet Pay, scan code payment and so on. This "card" a dozen years ago, more nouns fresh, with the formation of Internet plus concept, "card" as a carrier medium has changed. With the help of the NFC function of mobile phone and the unified technical specifications and settlement rules formulated by the issuing agencies or China UnionPay, people's mobile payment experience has been continuously improved, which has effectively promoted the development of the domestic mobile payment industry and the construction of mobile payment multi scenario application ecosystem. Cardlan as an important electrical equipment on the bus, to improve travel efficiency and convenience of the huge role in Internet plus impact on traditional industries, cardlan upgrading imperative, intelligent vehicle terminal consumption came into being. How to provide an intelligent vehicle consumer terminal that supports a variety of mobile payment methods is a very meaningful topic. The hardware and software design of the research on intelligent vehicle terminal consumption and implementation, through the demand analysis, the feasibility to use Cortex-M3 ARM processor and FreeRTOS operating system as the feasibility of the overall scheme of software and hardware, on this basis, focusing on the power circuit design and parameter matching of antenna, wireless data acquisition, visa free. Payment and other key technologies involved in the development process. This paper firstly introduces the important technology of intelligent vehicle terminal in the process of research, according to the investigation to determine the product demand, the overall design scheme of the hardware, software function module, the overall framework is reviewed, and then the hardware module, software in detail, and then encountered problems in the process of development and use the detailed analysis and summary. The main work accomplished includes logic encryption card, CPU card, USIM card, multifunctional millet payment, UnionPay flash pay card (visa free secret), the consumption function of two-dimensional code to pay, balance and transaction records query function, transaction records remote collection function, through the black box and white box testing and market trial. The final design goal has been achieved.
