摘  要

  [资料来源:http://THINK58.com]

随着计算机技术的发展,单片机技术已成为计算机技术中的一个独特的分支,单片机的应用领域也越来越广泛,特别是在工业控制和仪器仪表智能化中扮演着极其重要的角色。过去经常采用模拟电路、数字电路实现的电路系统,现在相当大一部分可以用单片机予以实现,传统的电路设计方法已演变成软件和硬件相结合的设计方法。在实际应用中,单片机经常要与各种传感器相结合组成一定的应用系统,以实现系统的自动检测与控制。

本文所设计的智能饮水机就是单片机结合传感器的一个简单应用。该系统设计综合单片机以及电子技术理论,从生活实际出发,完善了饮水机的功能。设计方案中,主要采用数字温度传感器DS18B20组成测温系统作为检测单元,并运用了AT89C52作为主机单元、 X5045EEPROM作为存储单元、HD7279芯片来管理键盘和显示器。整个设计系统实现三个功能,即加热、对温度上下限的控制和定时加热。与传统的饮水机相比,由于采用了自动检测和控制的电子设计技术,可较好地实现对水温的测量和控制,具有较广泛的应用前景。

Abstract

 

[版权所有:http://think58.com]

With the development of computer technology, single-chip technology has become the computer technology in a unique branch, SCM applications are increasingly widespread, especially in the industrial control and instrumentation play an extremely intelligent important role. To achieve automatic control of a system to detect sensors often need to control the volume of industrial production in the modern automated production processes in particular, the use sensors to monitor and control the production process parameters, which makes the application of sensors is the extensive, it is no exaggeration to say that almost every project a modern, can not be separated from a variety of sensors. In this paper, drinking fountains designed by the smart sensor is the single-chip combination of a simple application
The system is an integrated single-chip design, as well as the theory of electronic technology, from the reality of life, improve the function of the drinking fountains. Design, mainly composed of digital temperature sensor 18b20 detection unit as a temperature measurement system and the use of the 89C52, x5045, hd7279, clock chips, such as 1302 integrated device. The design system of three functions, namely, heating the upper and lower limits of temperature control and heating time to time. Compared with the conventional drinking fountains, as a result of the use of the automatic detection and control of electronic design technologies to achieve better temperature measurement and control, with a wider range of applications.
