精品毕业论文--基于单片机的饲料自动供给系统设计.doc

摘要
现代工业生产正处于一个劳动密集型,设备密集型,信息密集型向知识密集型转变的过程。在这一过程中,智能控制无疑起着重要的作用,单片机为核心的智能控制系统具有成本低,可靠性好的特点,同时具有实现下载和灵活设置参数的功能,具备扩展功能,可以增加控制方式,有很好的扩展性和兼容性.
本设计主要通过单片机对步进电机的控制完成带传动,,本文综合分析和对比了几种改造方案,最后使用单片机与步进电机组成系统。单片机系统是整个控制系统的核心,数据的读取和处理、电机的调速控制、数据的显示和报警都由它完成。本论文详细的分析了单片机控制板及其接口的组成和开发过程,介绍如何使用单片机、步进电机控制系统,以及使用单片机、键盘与显示、报警控制系统。对于实际应用系统实用方便与实用性是重要的,因此在论文中,从硬件和软件两方面分析和研究了整个系统的实用性与方便性,使得整个系统能够安全、稳定地工作。

ABSTRACT
Modern times industry production is in a change process of labor denseness, facility denseness and information denseness to knowledge denseness. Aptitude control plays a important role in this process. As a result of the aptitude control system based on SCM has the characteristic of low cost and good reliability and it has the function of download and agile parameter setup, agile spread at the same time, the system will be expansibility patibility.
The design mostly gets across the SCM control about stepping motor to fulfill belt drive, and achieve feed automatic-provide. According to the current condition and the request, this paper analyses and contrasts some reform project, then using single puter and stepping motor to constitutes the system .two stage control system. The SCM that is the center of the whole control system is used to collect and process the data, adjust the speed of the electromotor and display the data, give the alarm. This thesis not only fully discusses the constitution and designed process but also introduces how to use single puter, stepping motor control system and single puter, keyboard and vision, alarm control system.
For the practical and applied system, the reliability and facility is very important. So the reliability and facility of the whole system is analyzed from hardware to software o make the whole system operate safely and steadily.
Key Words: SCM; stepping motor; speed regulation
