基于单片机多点测温系统的设计
摘 要
温度是工业生产中常见的和最基本的工艺参数之一, 任何物理变化和化学变化的过程都与温度密切相关, 在许多生产过程中常常需要测量和控制几十以至几百个点的数据。如果用常规模拟仪表来完成这些任务, 由于检测点太多会使仪表台数相应增多, 系统可靠性随之下降, 维修困难。测量不精确是其主要方面,在这样的形式下,就需要一种能同时对多点温度进行测量,并能够进行数据传输。本课题用本课题以AT89C51单片机系统为核心,DS18B20智能传感器作为检测仪,通过系统总线及通信协议将采集的数据传送到主控机,进行进一步的存档、处理。主控机负责控制指令的发送,控制各个从机进行温度采集,收集测量数据,并对测量结果(包括历史数据)进行整理、显示和存储。主控机与各从机之间能够相互联系、相互协调,从而达到系统整体统一、和谐的效果,进而达到对多点进行温度监控的目的的系统。

Abstract
The temperature mon in the industrial and technological parameters of the most basic, any physical and chemical the process of change in temperature is closely related, in many of the process often requires gaging and controls and hundreds of the data. If you use a regular instrument to finish the task, because detection point too much will the instrument number of units corresponding number system reliability continue to decline, the maintenance of difficulties. No accurate survey is the main aspects, in such form, a kind of energy for more temperature measurement is made and can be used for data transmission. This issue with this subject in a monolithic integrated circuits AT89C51 system at the core, as intelligent sensors DS18B20 ignition-coil through systerm bus munications protocol would collect data to master, any record, processing. Master machine instructions. responsible for controlling the control of the different from taking the collection, data collection measures and the measurement (include historical data) for the display and storage. Master machine and from the interrelations between, harmony and achieve a unified system, harmony, and reach for more for the purpose of the monitoring system.
