Abstract


In recent years , with the development of science and technology , especially the development of communication technology , computer technology and sensor technology , data acquisition techniques used in the field of temperature test , made ??possible by real-time monitoring and control of the ambient temperature . In various fields of temperature measurement and control systems involving sensors, computers, communications , and other multi-disciplinary , international forefront of hot research field . The design of this project based on AT89S52 temperature measurement and control system has not the advantage of the geographical environment , climate , time of impact , and means of communication means of transmission of remote data acquisition system , the more the project cost and low-cost human resources , high reliability , maintenance-free and other advantages. The system temperature measurement elaborate design ideas and implementation methods of temperature measurement and control system as well as communication with the host computer , the paper system , a detailed analysis of each part of the circuit design principles , the details of the various parts of the design process . AT89S52 based temperature measurement and control system by the temperature acquisition , data transmission part and the host machine communication is composed of three parts . The temperature acquisition part of the use of the ATMEL Corporation production of low -power , high - performance CMOS8 bit microcontroller AT89S52 control center , digital temperature sensor DS18B20 collected temperature values ??into the microcontroller for data processing . Sense the temperature control system on the market now by the temperature level of regulation and control , there is little time control adjustment control . Added in the hardware design time control, i.e. the system can be set to work within a specified time , thus increasing the security of the system .
