基于单片机的温度巡检系统设计

AbstractThe system mainly uses a distance-free multi-point temperature measurement systembased on AT89C51 single-chip microcomputer and DS18B20 temperature sensor.The systemuses AT89C51 single-chip microcomputer to sequentially detect the temperature of eachmonitoring point to realize the functions of temperature detection,display and overheating.Thesystem mainly uses the single-chip AT89C51 microcomputer as the control core of the mainsystem.The display module LCD 1602A is held for identification and display.LCD1602A isused as a liquid crystal display to visually display the measured temperature value.The digitaltemperature sensor DS18B20 is used to detect the temperature of each channel,and themonitoring accuracy can reach 0.1 C.This article first introduces in detail the developmentbackground of the system and the functions used and its significance in the introduction.Thesecond chapter determines the design.In the third chapter,the overall design process is discussed,and the technical indicators and component selection are determined.The hardware blockdiagram design,hardware circuit design and various chip functions and usage methods in thesystem are carried out.The fourth chapter focuses on the analysis of each process of design.Thefinal chapter details the debugging software and debugging issues of the system.The multi-pointtemperature measurement and control system is based on a single-chip AT89C51 single-chipmicrocomputer.It has a simple hardware structure,multi-point temperature detection function,digital display,high precision and wide range of applications.It is widely used in actualproduction and life.Key words:digital temperature sensor,AT89C51 single chip,single-bus-2-
