摘 要 随着信息社会的到来，人类所拥有的信息种类和数量呈爆炸性增长，IC卡，一种方便安全可靠的高技术，高附加值的信息载体便应运而生。IC卡技术以其广泛的应用领域和巨大的产品市场成为近几年来我国信息产业的一大特点。与此同时，我国燃气收费管理长期以来都是以人工抄表为主，存在着工作量大、收费时间长、收费困难、效率低、易出错的问题，为了减少燃气收费管理中人力、物力的浪费，减少不安全因素，进行了“智能煤气表的研究”。这既是IC卡技术实际应用的进一步探索，也是燃气收费管理方式的改革。 本设计对智能IC卡煤气表控制装置的组成、功能及技术要求进行了理论上的分析和技术上的应用研究。设计依据低成本，高可靠性的原则完成了以下工作： 1. 软件设计中均采用模块化设计结构，完成了燃气表的计费功能以及故障的查询和处理。 2.采用性价比较高的AT89C51单片机作为控制装置的核心，控制装置的硬件电路实现了脉冲采集、数据存储、电磁阀驱动控制、IC卡读写、电源监测及声音报警和等功能。 3.本文用Visual Basic6.0成功地实现了对IC卡的管理以及煤气收费系统的管理。数据库软件具有建立用户档案、销售、写卡、统计、查询等功能。 关键词： IC卡技术 煤气表 AT89C51单片机 ABSTRACT With the coming of information society, human beings have the amount and type of information in the explosive growth, IC card, a convenient safe, reliable and high technology and high value-added information carrier will come into being. IC technology with its extensive applications and great products market in China has become a feature of the information industry. Meanwhile, Chinas gas charges administration have long been mainly on artificially meter, there are big workload and charging time is long, difficult charging, the efficiency is low, the error-prone problems, in order to reduce gas fee manpower and material resources in the management of the waste and reduce the safety factor, smart MeiQiBiao research. This is both practical application of IC card technology explore further, also is the reform of fuel gas fee management mode. Technical requirements makes a theoretical analysis and technical application research. Design basis low cost, high reliability principle completed the following job: 1. The software design is all adopt modular design structure, completed the gas meter charging functions and fault inquiries and processing. 2. The ratio of higher AT89C51 as control device, the core of the hardware circuit implementation control device of pulse acquisition, data storage, electromagnetic valve driving control, IC literacy, power monitoring and voice alarm and etc. Function. 3.
