Abstract


Temperature is one of important parameters to definite the status of materials,it indicates the thermo degrees of materials,and the test and control of temperature play the important parts in national defense,military,science experiments and the production of industry and agriculture.With the development of industry,demand on temperature measurement becomes higher and higher.The traditional temperature measurements used in industry have high accuracy but cannot be used continuously,and vice versa.So it is an important research item in industry temperature measurement to find a method with continuous testing and high accuracy.This thesis is based on the theory of blackbody and infrared radiation,give us a new way called portable continuous temp-measurement.This way is putting a portion of blackbody high temp-endurance conduit to the top of temp-measurement probe.Then put the conduit into the medium that intended to measure,the conduit can directly contact and measure the high-temp source,by this means the probe can be insert to the metal water,which can eliminate the interrupting of smoke and sinter.The material that can be used as fire-endurance for normal blackbody high-temp conduit are:ceramics,carbon,charring silicon etc.The blackbody radiation erect by heating is transferred to an infrared sensing probe which is not directly contact with the high-temp source in a sealed medium where photo fiber is set,by that way the measurement can be done without the interrupting of light from backgrounds and other bad gas.When the probe gets the temperature,the temperature signal is transferred into volt signal by the amplifier.Then the volt signal is transferred by A/D into digital signal to MSP430,the MCU calculates and compares the information of temp and status, which is displayed on the LED screen with voice output.It can be done by RS485 to communicate with PC,and make temperature graph,note the information at any time. This type of technology,gets the rid of the low accuracy of non-contact measurement,takes the place of traditionally used platinum and germanium,and also makes it cost less.It gives us a new and effective way to measure the temp of molten steel and molten iron continuously and precisely.
