基于DS18B20的多路温度检测系统设计

基于在工厂或企业,需要对多点进行温度检测,本文介绍了一种能巡回检测各点温度的设计,以数字温度传感器DSl8B20作为现场测温元件,以AT89C51单片机作为控制单元组成的可以对多点温度进行检测和控制的系统,给出了系统的硬件电路图和软件流程图。在系统中,数据的采集和控制都实现了数字化,能实现对各点温度的实时监控,并具有超限报警和指示功能。仿真实验结果表明,本设计抗干扰性好、设计灵活、方便,适合于现场温度测量。

Design of the multi-channels temperature detecting system based on DS18B20

Based on the factory or enterprise,we need to multi-points temperature detection,this paper introduces a design which can test temperatures of different points,With digital temperature sensor DSl8B20 as the temperature measurement devices,with AT89C51 as control units of multi-point temperature can be detected and control system,and gives the system hardware circuit and software flow chart.In the system,data acquisition and control all digital,can realize the real-time monitoring of multi-points temperature,and has the off-gauge alarm and instruction function.The simulation results show that the design anti-interference design,flexible,convenient and suitable for the temperature measurement.
