摘　　要：基于AT89C51单片机的全自动坐便器控制系统,主要由红外感应系统,单片机控制系统和外围设备及其驱动电路3部分组成。该系统通过2个红外感应中断,分别感应到人的靠近和人体停留的时间,并将信息传送给单片机进行处理,由单片机进行分析,根据人体停留的时间长短做出判断,并决定采用合适的工作方式,通过电机转动座圈和上盖,并驱动落水阀和杀菌除臭电路工作。该系统有效地节约水资源,而且可以杀灭各种有害菌,保证人们的身体健康。The full-automatic urinal based on the AT89C51 is mainly composed of IR induction,controller based on single chip computer,peripherals and their driving electrical circuits. This system responds interruption through two IR inductions, which can induct the nearing of a person and can induct the length of time that the person stayed. The information is delivered to the single chip computer,and then the single chip computer is carried on a processing according to the information and decides to adopt which kind of work method to run, and turn to arousing motors to turn the upper cover, and drives the falling water equipment. The system saves efficiently water resources,can kill various harmful germ to assurance people＇s healthy.
