摘要
基于预付费燃气表的IC卡查询与充值,提出一种手机音频读卡器解决方案,采用模块化设计思想。在采用的技术方案中创造性地融入曼彻斯特(Manchester Encoding)编解码技术,有效地克服了手机音频通信可靠性、适配性差的缺点。文中对项目研究的技术原理和读卡器的软硬件系统架构做了详细描述,并针对其中的一些技术难点提出解决思路。本项目达到了客户要求,技术上得到了积累和提高。
Based on the inquiry and recharge of IC card for the prepayment gas meter,an audio reader solution for mobile phone is pro- posed.The project adopts the modular design ideas.In addition, the designer creatively integrates Manchester encoding and decoding tech- nology into the design.It solves the shortcomings of the mobile phone audio communication reliability and the poor adaptability.The hard- ware and software system architecture and the principle of reading the project of the card reader are described in detail,and for some of these technical difficulties, the designer proposes the solutions.The project meets the customer requirements.
