1、毕业设计(论文)论文题目基于单片机的智能水表设计学号：XXXXXXXX姓名：XX专业：电气工程及其自动化系别：指导教师：XXXXXXX年XX月摘要本文以智能IC卡水表系统为研究对象，研究了基于单片机的智能水表的设计。首先提出射频IC智能水表系统的设计方案;其次对系统硬件电路结构进行了设计;再次介绍了系统软件设计原则以及控制流程。该智能水表以低功耗、低电压、高性能的8位单片机AT89C51为核心，以防干扰性能极高的双干簧管为流量传感器，另外本设计还有可显示状态字的LED显示屏以及报警模块，剩余水量到报警值或为零时，门阀驱动电路运
2、作，自动关阀中断供水。采用射频读写芯片，当IC卡贴近感应区时，通过读卡芯片读入所购水量并和水表内剩余水量累加，并写入射频卡水表内存储器。本设计不仅可以改善传统水表功能单一的缺点，测量精度更高，功能更强，可靠性更好，还能从根本上改变用户先用水后交费，采用人工抄表、按户收费的现状，彻底改善工作量大，收费周期长，收费困难，效率低下等缺点。关键词：智能水表；射频IC卡；AT89C51iABSTRACTWiththeintelligentICcardwatermetersystemastheresearchobject,research
