Description

The present invention relates to a temperature measuring device and a temperature measuring system that measure the body temperature of a subject in a non-contact manner and determine and display the admission permission or the entry prohibition of the subject.

As a preventive measure against the spread of infection by the new coronavirus in recent years, in public facilities, commercial facilities, complex buildings, event venues, etc., a temperature measuring device equipped with a thermal camera that can measure the body temperature of the subject in a non-contact manner is used. Measures have been taken to detect fever, which is a major symptom of virus infection, and to ban fever from entering facilities.

As a temperature measuring device of this type, for example, a technique disclosed in Non-Patent Document 1 is known. Of these, the face recognition type technology automatically detects the face part when the subject is photographed with a camera, the infrared detector detects the infrared rays emitted from the face part, and the surface temperature of the face is calculated from the detected value. However, when this temperature exceeds the threshold value, it is recognized as an abnormal body temperature, and the subject is notified by a screen display, an alarm sound, or the like that the temperature is abnormal.

Further, as a conventional temperature measurement system, for example, a technique disclosed in Non-Patent Document 2 is known. In this technology, a temperature measuring device similar to the technology disclosed in Non-Patent Document 1 is configured to be capable of bidirectional communication via a wired or wireless LAN (Local Area Network), and a PC connected to the LAN ( Personal Computer) can be used to collectively manage the data acquired by a plurality of temperature measuring devices.
