基于DS1616的定时数据采集系统

对于监测类仪器仪表而言，准时采集和记录数据是非常必要的，同时也要考虑能耗问题。本文在介绍Dallas公司新近推出的一种带实时时钟的集成数据采集记录器件DS1616的结构和工作原理基础上，给出了综合考虑以上因素后的一种定时数据采集系统。它由实时时钟器件DS1616和线性稳压器MAX603等组成。通过AT89C51单片机对DS1616的初始化，可实现系统按预先确定的时间段开机与关机；利用DS1616还可实现环境温度和三路模拟输入信号数据的定时采集与记录。该系统很适宜在便携式数据记录设备中的应用。  Timing Data Acquisition System Base on DS1616

Abstract: For many detecting instruments and meters, acquiring and recording data on time is very important. Also, the question of consuming energy must be considered. In this paper, the structure and operating principle of DS1616 that is a real time clock and recording data device are introduced. After considering above factor, a kind of timing data acquisition system that consists of RTC DS1616 and linear stabilizer MAX603 was given. Through setting DS1616 with single chip computer AT89C51, it realizes that the system is powered on and off at ordinary time. With DS1616, the function of timing acquiring and recording environment temperature and three channel analog input signal data is realized. This system is very suited to having application in portable data recording equipment.
