专业自动化
摘要
CO测试仪利用A/D转换原理,将被测模拟量转换成数字量,并用数字方式显示出测量结果。A/D转换器的精确度影响数据显示的准确度,本设计采用ADC0809对输入模拟信号进行转换,控制核心AT89S51单片机对转换的结果进行运算和处理,最后驱动输出装置显示数字信号,通过keil软件对所设计程序进行编译和调试,keil软件提供了包括C 编译器、宏汇编、连接器、库管理和一个功能强大的仿真调试器等在内的完整开发方案,通过一个uViSion集成开发环境将这些部分组合在一起。
将keil软件与proteus软件结合,通过Proteus仿真软件实现接口电路设计,将编好的程序输入keil软件中,进行编译,编译结束将产生一个HEX格式的文件,将其载入到proteus环境中,进行实时仿真。Proteus软件是一种电路分析和实物模拟仿真软件。它运行于Windows操作系统上,可以进行仿真、分析各种模拟器件和集成电路,是集单片机和SPICE分析于一身的仿真软件,功能强大,具有系统资源丰富、硬件投入少、形象直观等优点。

Abstract
CO tester using A/D conversion principle, to convert the measured analog to digital, and show the result in digital way . A/D converter’s accuracy impact the accuracy of data , we use ADC0809 to convert the input analog signal in this design, the control core-AT89S51 single-puting and processing to the result of the conversion, the last drive the output device to show the digital signal, use keil software pile and debug the design process, keil software provide plete development program including piler, macro assembler, connectors, database management and a powerful debugger, through an integrated development uViSion will ring static these parts together.
bine keil software and proteus software, complete the interface circuit design through the proteus simulation software,Input pleted procedures to keil software, and pile, when piler ends, it will generate a HEX file format, and loaded it into the environment of proteus, go to real-time simulation. Proteus software is a kind of circuit analysis and simulation software. It runs on windows operating systems, can be simulation, analyses various analog devices and integrated circuits. It is an analysis of single-chip and SPICE of simulation software, powerful, rich in resources with the system, less hardware investment, the advantages of visual image.
