文档介绍:摘要
本系统以单片机SST89E564为核心,设计了一个用于对冲天炉中温度的高精度自动调控和对料位、风压及风量等指标进行检测并显示的数据采集控制系统。在总结分析数据采集系统的基本构成、种类及其特点的基础上,本着方便、实用、可靠及经济等设计原则,详细介绍了将单片机数据采集应用到冲天炉中的具体实现步骤,设计开发了基于单片机SST89E564的数据采集系统。该系统能够对冲天炉传送过来的四路1~5V的模拟量进行采集,并对其进行监控,以判断冲天炉的当前工作状态是否正常,并在必要时给出相应的报警信息。此外,该系统配有能实时显示数据采集结果的LED显示器模块同时为了满足数据处理和传输的需要,系统还留出了串行通信接口,可以通过RS-232C总线将采集到的数据发送到PC机显示和处理。数据的运算和处理都是由单片机SST89E564调用不同的多字节浮点数子程序来实现的。本设计当中,子程序主要有四字节浮点数加法、乘法、除法等。本系统借助51单片机集成开发环境MedWin来进行编程和离线仿真,这使得设计开发过程变得更方便、快捷。

Abstract
This system bases on SST89E564 microcontroller. I have designed data collection system that it is used for regulating and controling temperature ,detecting feed place and wind pressure and measure. For the proper of the convenience, practical and dependable and economic etc, this paper designs principle in tallying up to analyze data collecting the system based on constitute, the foundation between category and its characteristics. This paper detailed introduces the actually procedure of the single machine data to apply to the cupola. And design the data system based on single chip system can collect 1-5v four-way simulation transmits by chongtian stove, it is also be supervised and gives as occasion arise to report to the police the information homogonously. In addition, this system has the LED display mold correspondence. .In order to satisfying the needs of data andling and transfer, the system has designed the munication interface, and it can ransmit the frequency to puter by way of RS-232C bus. These accurate data handlings are all realized by the different multibyte float-point number broutines of SST89E564 microcontroller. In this design, subroutines chiefly have four bytes floating number addition, multiplication and division etc. This system proceeds to weave the distance with off-line imitate true with the help of 51 single chip gather development environment makes the design evelopment process e more convenient and fast.
