基于DS18B20的多路温度检测系统设计

摘要

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。%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 DS18B20 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
