Description

Infrared ray body temperature detection device applying position control method}

The present invention relates to an infrared body temperature detection device to which a position control method is applied, and more particularly, to an infrared body temperature detection device to which a position control method is applied to measure the body temperature of a subject by rotating or moving an infrared sensor unit from a frame.

Among medical diagnostic devices, an infrared thermal diagnosis device is being used to diagnose the pain area by detecting the temperature of the human body and outputting the temperature difference between the pain area and the normal human body part as a thermal image. The infrared incident beam source generated from the pain area is passed through only the wavelength band to be detected by infrared rays by the filter and is incident on the sensing element. The sensing element converts the incident infrared light into an electrical signal according to the wavelength and detects the temperature for each wavelength band. It is output as a two-dimensional thermal image, and it can be used to diagnose various diseases.

The number of image pixels for thermal detection of each infrared detected by the conventional infrared detector is determined according to the arrangement. For example, the number of horizontal sensors (H) by the number of vertical sensors (V), the detector array is 120(H)X120(V), and the number of image pixels is 14,400.

According to the provisions of the international standard (IEC 80601-2-59:2008) and the provisions of medical device items and grades (announced by the Ministry of Food and Drug Safety), at least 240 images of medical infrared imaging devices in sub-class A21030.01 The size of the effective measurement surface should be at least pixel X 180 image pixels. In addition, it is prescribed that the thermal image of the face must be able to fill at least 180 image pixels X 135 image pixels. In order to satisfy these regulations, medical infrared detectors are being researched/developed using an array detector of 240X180 (43200 pixels) or more.

However, as the number of pixels increases, the cost of the infrared sensor increases, the signal processing electronic circuit processing each pixel signal becomes complicated, and the system cost increases due to an increase in data transmission and reception and storage. In addition, since the system volume increases with the increase in the number of detector pixels, an installation place is required and a heavy support is required, there is an inconvenience in carrying. In addition, in the case of acquiring a local thermal image, there is no improvement in spatial resolution when using a general scanning method. However, when improvement in spatial resolution is required, there is a disadvantage in that the subject has to move the position to shoot or move the infrared detection device itself.
