基于单片机的多路温度检测系统

ABSTRACTIntelligent temperature detection has developed rapidly in today's society and reached anunprecedented height.The main reason must also be attributed to the development of automaticcontrol technology,modern sensing technology and new materials and new processes.Intelligenttemperature detection is involved in many fields,such as defense,industrial production,andtechnology research and development.With the development of this technology,society isconstantly improving,and the production process is gradually improving the technology.Temperature detection and control require more standardized and high technology.So far,thenew electronic technology has been very mature,microelectronic computers have been used bythe general public,and single chip microcomputer systems are used in temperature detection andcontrol systems,mainly because it has the following advantages:stable performance,easyoperation,and high cost performance.The components of the system designed this time are as follows:single chip microcomputer,computer monitoring system and data acquisition system.The sensor is connected with the singlechip microcomputer to measure the temperature data.This design is not only modular but alsohierarchical.In this system,temperature data can be displayed in real time and the data contentcan be stored.The data transmission between the computer and the sensor can be used as amedium through the single-chip microcomputer.In this course design,mainly completed the following two aspects:The first is the systemdesign plan,mainly the working principle and design function.The second is hardware design,including the choice of DS18B20 temperature sensor,the choice of single chip microcomputer,the choice of digital and analog input channels.Keywords:MCU,DS18B20,temperature detection
