基于单片机的多路温度检测报警系统的设计

摘要

当今社会温度的测量与控制系统在生产与生活的各个领域中扮着越来越重要的角色，大到纺织厂，工业冶炼，环境检测，电力机房，冷冻库，粮仓，医疗卫生等方面，小到家庭冰箱，空调，电饭煲，太阳能热水器等方面都得到了广泛的应用，温度控制系统的广泛应用也使得这方面研究意义非常的重要。系统中通过时钟脉冲实现了温度的单一和循环显示。在温度超过设定温度时可以对报警温度和实际温度交替显示，从而给予更多的信息。按钮结构简单、应用灵活、易扩展，很大程度上提高了自动检测的效率，使本系统更加的智能化、人性化。

本文介绍了一种基于AT89C51单片机，利用AD590进行8路的温度采集，通过ADC809进行模数转换的多路温度检测报警系统。我国温度测控设施计算机应用，在总体上正从消化吸收、简单应用阶段向实用化、综合性应用阶段过渡和发展。在技术上，以单片机控制的单参数单回路系统居多，尚无真正意义上的多参数综合控制系统，与发达国家相比，存在较大差距。我国温度测量控制现状还远远没有达到工厂化的程度，生产实际中仍然有许多问题困扰着我们，存在着装备配套能力差，产业化程度低，环境控制水平落后，软硬件资源不能共享和可靠性差等缺点。在今后的温控系统的研究中会趋于智能化，集成化，系统的各项性能指标更准确，更加稳定可靠。

Multi—channel temperature detection alarm system based on single chip design

Abstract

This article introduce a Multi-temperature detection alarm system based on AT89C51 microcontroller,AD590 for temperature and ADC0809for the analog digital conversion. System achieved by clock pulse and a single temperature cycle showed that the temperature set switch functions. Multi-channel temperature detection alarm system based on AT89C51 was introduced. In order to save ports, enlarges integrated circuit expand the function later, the data series of sensor system enter the line SCM. Systems through the control button to achieve the real-time setting of all the different alarm temperature, and the realization of multi-channel or single switch temperature display, which can carry out multi-channel detection and also can be carried out as a one-way monitoring.

This paper introduces a kind of based on AT89C51, 8-way by AD590 temperature acquisition, through ADC809.To convert the modulus of multi-channel temperature detection alarm system. Temperature measurement and control facilities, computer application in our country, in general are from digestion and absorption, easy to practical application stage, transitional stage, comprehensive application and development. In technology, in the majority with single-chip microcomputer controlled single parameters of the single loop system, Temperature measurement control in our country present situation is far from reach the level of factory, there are still many problems in practical production, there are equipment supporting ability is poor, low degree of industrialization, environment control level lags behind, In the study of a temperature control system in the future will tend to be more intelligent, integrated, each performance index system more accurate, more stable and reliable.
