The design of the liquid inputing system basing on one-chip computer
Abstract:With the development at full speed of science and technology in recent years, the application of the one-chip computer is being moved towards deepenning constantly, drive tradition is it measure crescent benefit to upgrade day to control at the same time. In measuring in real time and automatically controlled one-chip computer application system, the one-chip computer often uses as a key part, only one-chip computer respect knowledge is not enough, should also follow the concrete hardware structure , and direct against and use the software of target's characteristic to combine concretly, in order to do perfectly.
The system is designed to construct a wired monitor system of a master station controlling multiple slave stations,with a one-microcontroller Atmel89C52 as the key, complimented by stepper motor drive, keyboard, LCD display, LED display and photoelectric censor data collection out side circuit. The combination of fuzzy control working on the motor drive can effectively reduce the amount of over regulating and stable error and shorten the time of adjusting.

第1章 单片机及多单片机应用(yìngyòng)系统
单片机的概述(ɡài shù)
单片机，也称单片微型计算机，是微型计算机家族中的一员，它以独特的结构和超群的优点，深得各个领域的青睐，应用(yìngyòng)十分之泛，近年来开展(kāizhǎn)极其(jíqí)迅速。世界上的各个半导体厂商都抓住这个时机，推出自己的产品，一时间单片机如雨后春笋般蓬勃开展和流行起来。
在近30年的时间里，电子计算机的开展经历了从电子管、晶体管、中小大体集成电路到大规模集成电路四个阶段，尤其是随着大规模集成电路技术的飞跃开展，20世纪70年代初诞生的单片机微型计算机，使得计算机应用日益广泛。而单片机的问世，更进一步推动了计算机应用技术的开展，使计算机应用渗透到各行各业，到达了前所未有的普及程度。
单片机的特点与应用
一、单片机的特点：
〔１〕重量轻、耗电少、价格低、电源单一。
〔２〕抗干扰能力强、可靠性高。芯片本身是按工业测控环境设计的，其抗工业噪声干扰优于一般的通用CPU；程序指令及常数、表格固化在ROM中，不易被破坏；许多信号通道均在一块芯片内。
〔３〕集成度限制，片内存储器容量较小。一般ROM小于8KB，RAM小于256个字节，但可在外部扩展，通常ROM、RAM可分别扩展至64KB。
〔４〕面向控制，控制功能强，运行速度快。其结构组成与指令系统都着重满足工控要求。指令系统中均有极其丰富的条件转移指令，I/O口的逻辑操
