临沂师范学院 本科生毕业论文（设计） 题 目：基于单片机的人体红外探测智能冲厕电路设计 姓 名： 系 别： 信息学院 专 业： 电气工程及其自动化 班 级： 2007.2 学 号： 指导教师： 徐波 2010年8月3日  摘 要 论文运用嵌入式应用系统技术和智能检测与控制技术，设计了基于单片机技术的智能型感应式冲水系统。该冲水系统利用传感器检测人体发出的红外线信号，由单片机接收并作出智能判断，控制电磁阀的开启，然后经内部软件程序设定一定时间的延时，关闭电磁阀。此种设计方案可以达到环保、节水的目的，克服了现有公厕冲水系统浪费水资源及手动操作不卫生的不足。 论文论述了设计的理论基础、论证了设计方案，讨论了PIC12C508A单片机、嵌入式系统及其开发技术、智能检测与控制技术。论述了基于单片机的人体红外探测智能冲厕硬件电路设计和软件程序设计，抗干扰设计及软硬件调试和组装等。对硬软件抗干扰技术和PC板的抗干扰设计做了详细论述。达到了整个系统实现全自动操作，免除人为动作，既能满足冲厕的卫生要求，又最大限度地节约了水资源的目的。 【关键词】单片机； 红外检测； 智能冲厕； 节水； Abstract Papers the use of embedded system technology and intelligent application of detection and control technology, design technology based on single-chip smart sensor flushing system type. The flushing system uses the human body detection sensor of the infrared signal sent by the single-chip receiver and make intelligent judgments, control solenoid valve to open, and then the procedures set by the internal software of a certain period of time delay to close the solenoid valve. This design can achieve environmental protection, water conservation purposes, to overcome the existing public toilets flushing waste water system and inadequate manual unsanitary. Paper discusses the theoretical basis for design, design verification program to discuss the PIC12C508A microcontroller, embedded systems and the development of technology, intelligent detection and control technology. On the human body based on the single-chip infrared detection Intelligent flushing hardware circuit design and software programming, hardware and software design and anti-debugging and assembly. Hardware and software of anti-jamming technology and anti-jamming design of PC board discussed in detail. The entire system to achieve fully automatic operation, from human action, both to meet the
