【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热点。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IC卡燃气表控制装置”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。 本课题对智能IC卡燃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)用功耗低、价格便宜的PIC系列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、电机阀驱动控制、IC卡读写、电源检测以及声音报警和ICD液晶显示等功能。 (2)模糊控制原理解决了电机阀的控制问题，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。 本装置同样适用于各类水表、电表等其它流量计量装置中，如在此基础上做进一步的改进，将更具有经济性和实用性。更多还原

【Abstract】 With the approaching of information society, sorts and amount of information which human being owned increase explosively, IC-a kind of convenient, safe and reliable information carrier which contains high technology and high value-added spring up. Due to its wide applied field and vast product market, IC technology becomes the hotspot issue in the field of information industry in recent years. Meanwhile, artificial copying meter is a main form in management system of gas charge for a long time in our country. There are many disadvantages in old management system. For example, much work, difficult charge, lower efficiency and mistake often arise. In order to reduce the waste of manpower and material resource in gas management and to reduce unsafe factors, This project does research on Intelligent card and gas meter control device which is the further explored to the practical application of IC technology and is also a reform in management system of gas charge.This project makes theoretical analysis and does technological applicable research on the structure, function and demand of technology on control device of IC for gas meter. According to the principle of lower cost, higher reliability, the design completes much work. The contents of project are as follows:(1) PIC Micro-controller which is lower-power and lower price is the core of control device .The whole circuit realizes the functions of collecting pulse, keeping data, driving electric machinery valve, reading and writing IC, detecting power supply, sound alarm and liquid crystal display.(2) The theory of fuzzy control resolves the control of electric machinery valve. The software design that is the module structure realizes the function of gas meter counting, inquiring and dealing with the malfunction.This device can also apply to electric meter, water meter, and other intelligent counting control device as IC. If this device is improved at the base of formerly device, it will possess economical and applied characteristic.Candidate: Yu XiuliSpeciality: Electrizationand automatizationof Agriculture Supervisor: Prof. Ouyang Binlin更多还原
