Design Of Remote Temperature Measurement And Control System Based On WI-FI Transmission

With the improvement of living standards and technology, environment and healthstatus are increasingly concerned. Therefore,newrequirements of temperature measurement are proposed, about the health of the Many technology companies have launched smart watches and other wearable devices which are used to measure the temperature. Wearable watches can easilymeasure body temperature.But how to measure the outdoor temperature, to measure temperature in harsh industrial environments, and tomeasurethe temperature which is out of human reach? Such temperature measurement can not by accomplished by a wearable watch, or by a traditional thermometer or a temperature sensor. To solve this problem, I designed a temperature measurement and control system based on Wi-Fi, which can be usedmeasure the temperature of the outdoors, corrosive gases, high pollution harsh environment, harsh industrial environments and or other ambient temperature. The designed system can also display the temperature of the environment on the computer, and intelligentlly control the temperature to achieve the required valuse.In this paper, the purpose is to measure the temperature through the intelligent temperature measurement and control system and extend the idea of Wi-Fitransmission into the field of industrial control and intelligent home-based applications,whichcontrol various physical information, such aspressure, flow, speedand multimedia information transmission between the Wi-Fi-based device.This thesis desings and implementsa remote intelligent temperature measurement and controlsystem includingthe hardware design and software system.Thehardware system inlcudes STC89C52RC microcontroller as the core control system, DS18B20temperature sensor subsystem, temperature display subsystem, heating equipment control subsystem,232Wi-Fi wireless network subsystem and computer wireless network subsystems, which are introduced in detail in the thesis.Software system includes a single-chip control system using C51programming and the application control system by using VB. This paper introduces the C51, VB basics, theflowcharts of some control programs and the related sourcecode, and thenthe overall systemdesignis implemented and some conclusions are give.
