Research On Infrared Thermometer

The working theory of infrared thermometer is turning infrared radiation which is collected from the target into temperature volume. The traditional temperature measuring ways are replac- ed by the infrared measuring way for their characteristics like non-contaction,high speed and accuracy and easy checking of temperature.The infrared temperature measuring systerm invented in this thesis is used in these situations like airports,stations and so on ,where there are too many people and a large flow of crowed.The thermometer collectes temperature dates in the way of high-speed laser scanning,the dates are send to the PC via wireless transmission.The monitoring center computer handles the temperature dates and output heat map which is easy observed.The thermometer researched in the thesis requires to achieve the following functions:high precision,non-missing checking,over-temperature alarm,over-temperature point tracking and heat map analysis,and the sofetware and hardware of the systerm were mainly studied. High performance microcontroller MSP430C412 was used as the main control module in the lower computer.The best devices are choosed and connected to collect and handle the temperature dates.Over-temperature alarm function can be achieved by microcontroller programming.When there is a over-temperature point ,the scanning laser will note the point's coordinates and send it to intelligent ball-like tracking camera,then the point tracked and displayed.The overtemperature points will not missed.Dates are handled in the monitoring center computer,this technology ensures the displaying accuracy.This research has practical significance.The infrared heat image and video image are mixed in the temperature measurement system.The two moldes display at the same time and in difrent field.This system can achieve remote,real-time and online monitoring.
