摘　　要：利用AT89C52单片机为核心器件,设计的多路信号实时监测系统采用串行技术实现多路参数的实时监测。其最大特点是所采用的单片机、A/D转换器、数据存储器、显示模块、时实时钟、打印机等体积都很小巧。该系统全部采用串行,除了具有对采集的数据及采集数据时的时间进行记录、显示、打印、掉电保护等一般功能外,还具有体积小、成本低、性能稳定可靠,可应用到烟草业、制药业,对生产过程中的温度、湿度等多路信号的监测;也可应用到养殖业,对养殖水中的一些物理参数如温度、PH值等多路信号的监测等。In this paper, a real- time multi- channel monitoring system by using AT89C52 microcontroner as tne core component is introduced. This system uses serial communication technique to implement real - time multi - channel monitoring. Its major characteristic is the tiny structure of the microcontroller,the A/D converter,the data memory,the display module, the real time clock,the printer and so on. The serial communication technique is used extensively in the system,providing not only the general functions of recording, displaying, printing the acquired data and the time of the acquisition, and power - off protection,but also the tight volume,low cost,and stable and reliable performance. This system can be applied in the tobacco industry,and the drug manufacture industry to monitor the temperature,hurnidity and other multichannel signals in the production process,also it can be used in the cultivation industry to monitor some physical parameters in the water such as the temperatures,PH value and so on.
