基于MCS-51单片机数据采集控制系统
摘要:随着电子技术的飞速发展,数据采集系统的应用越来越广泛,在工农业生产中,经常要对一些温度、湿度、电压、电流等参数进行采集,再利用采集的数据进行分析,以实现更好的控制。因此,数据采集系统的研究很重要。本文介绍了一种基于单片机的温度数据采集系统,利用单片机和多路温度传感器进行分散式数据采集,并将采集到的温度通过液晶显示器显示,同时可以利用按键设置异常温度值,当测量的温度超出这个异常值时,系统可以启动蜂鸣器报警提示。本文提出的设计方法电路简单易懂、成本低廉、测量结果准确、稳定性高。

Based on the MCS-51 single-chip puter data acquisition control system
Abstract: With the rapid development of electronic technology, the application of data acquisition system is more and more widely, in the industrial and agricultural production, the temperature, humidity, voltage, current, parameters are collected, and analyze the accumulated data, in order to achieve better control. So, data collection system study is very important. This paper introduces a kind of based on single chip puter temperature data acquisition system, using single-chip puter and temperature sensor for distributed multi-channel data collection, and the collected temperature are shown through liquid crystal, also can use the buttons to set the value of the abnormal temperature, when measuring temperature beyond this unusual value can start a buzzer alarm prompt. This paper puts forward the design method of the circuit is simple to understand, low cost, measurement results are accurate, high stability.
Key words: Single-chip puter; DS18B20; Temperature sensor; LCD monitor
