Application Research Of Infrared Temperature Measurement Technology On Electromagnetic Heating Device

With the continuous improvement of people’s living standard, the application of electromagnetic heating device in daily life is becoming more common,temperature measurement of the electromagnetic heating device for people also calls for more and more accurate.Induction cooker pot body temperature measurement, for example, the traditional way of measuring temperature need contact with each other, difficult to achieve the purpose of real-time and accurate temperature measurement, but infrared temperature measurement technology can realize the purpose of non-contact and real-time temperature measurement.Consequently,In this paper, combined research status at home and abroad, cooker selected for the study, developing an infrared temperature measuring device, and using the temperature measuring device to measure the temperature of the pot of the cooker, and establishing BP neural network model and heat transfer model to solve, ultimately,achieving the temperature forecast of the medium inside the cooker pot. Finally, analysising the advantages and disadvantages of temperature measurement and improvement. The main contents are as follows:First of all, summarized the research status at home and abroad and the main study content of this paper, more detailed description of principles of the subject involved, Such as the cooker works principle, radiation thermometry principle,infrared sensor technology progress, etc.Secondly, to the design of the hardware and the software of infrared temperature measurement devices, made a more detailed description. The device consists of a number of modules, including an infrared temperature sensor module, LCD liquid crystal display module, Bluetooth serial port passthrough module, power supply circuit modules, etc. After the completion of the design of the device, began to the calibration experiment.In the Final, using the infrared temperature measurement device to measure the temperature of cooker cookware. First, select the appropriate thermometer, select the appropriate measurement points, then measure the temperature of the outer surface ofthe cookware and the temperature of the medium inside the cooker pot, and establishing BP neural network model and heat transfer model,then to process the temperature data of the outer surface of the cookware,ultimately,achieving the temperature forecast of the medium inside the cooker pot. Compared the predicted result with the real temperature of the medium inside the cooker pot,Finally, analysis of the advantages and disadvantages of the temperature program and suggest improvements program, and summary and outlook.
