摘　　要：本文围绕基于燃气行业售气系统的卡片兼容性问题进行了研究。本文对当前行业内存在的售气系统存在的问题进行深入的分析和探讨,针对当前系统中存在的问题,提出了对应的改进方法,最终制定出了一套行之有效的安全解决方案。针对卡片兼容性的问题,采用自研安全读卡器来进行多卡种的识别判断,最终实现一个读卡器自动识别多种卡片。最后,对所做的研究进行软硬件研发,对其所有的功能进行实现与测试。实验的结果验证了本文提出的设计方案在卡片的兼容性上能够满足设计需求。本文的研究工作,最终在燃气行业上对应的系统上得到了实现,本文的研究成果对燃气行业售气系统的架构具有一定的指导意义与对应的实际价值。This paper focuses on the card compatibility of gas sales system in gas industry. This paper deeply analyzes and discusses the problems existing in the current gas sales system in the industry, puts forward corresponding improvement methods for the problems existing in the current system, and finally formulates a set of effective safety solutions. Aiming at the problem of card compatibility, the self-developed security card reader is used to identify and judge multiple cards, and finally one card reader can automatically identify multiple cards. Finally, the software and hardware of the research are developed, and all its functions are realized and tested. The experimental results verify that the design scheme proposed in this paper can meet the design requirements in terms of card compatibility. The research work of this paper is finally realized in the corresponding system in the gas industry. The research results of this paper have certain guiding significance and corresponding practical value for the architecture of gas sales system in the gas industry.
