文档介绍：摘要为了适应国家的用蒸汽制度的改革,缓解蒸汽部门因先用汽后付费所带来的资金紧张,研究和利用现代智能技术,实现自动供汽势在必行。智能控制器的推广,不仅可以提高蒸汽供应管理部门的工作效率,并在技术上,为节省蒸汽,合理的利用蒸汽创造了条件。本论文是一个关于智能蒸汽预付费控制器的研究,是基于单片机的一种应用和发展。本设计是一单片机为核心,通过单片机读取 IC 卡的数据并进行处理,并控制外接阀门控制电路,以达到控制供应蒸汽的目的。本论文首先介绍了 IC 卡的历史和现状,阐述了设计 IC卡控制器的关键技术,然后介绍了 IC卡的结构和特点,工作原理。再次是详细阐述了包括 IC 卡读写电路、阀门控制电路、键盘电路、电源电路等在内的硬件电路,最后详细阐述了软件设计部分。关键字:IC卡蒸汽预付费控制器单片机 Abstract In order to adapt to the reform of the country's steam system, and to ease pany's funds pressure because of the method that one will pay for the money after use the steam, researching and using the modern intelligent technologies to achieve automatic steam supply is imperative. The promotion of the intelligent controller can not only improve the work efficiency of the steam supply management, but also create the conditions in order to save steam, to reasonably use the steam. This paper isa study based on an intelligent steam prepaid controller and based on the application and development ofa microcontroller. The core of the design isa microcontroller, then the microcontroller reads and processes the IC card data , and controls an external valve control circuit, and to reach the goal of controlling the supply of steam. Firstly, this paper described the history and current status of the IC card. And secondly, it explained the key technology of the design of the IC card controller, and then described the structure and characteristics and the working principle of the IC card. Thirdly, it elaborated hardware circuit including, IC card reading and writing circuit, the valve controlling circuit, the keyboard circuit, power circuit. Finally , the paper elaborated the design of software.
