The present invention relates to an access control system and method, and more particularly, to an apparatus and method for controlling access control through an efficient and accurate heat measurement method.
A person is a warm-blooded animal (homeotherm) that keeps the body temperature constant at all times. Body temperature refers to the temperature inside the body, body temperature is very different depending on the body part, but the ankle more than 6cm from the rectum temperature measured in the standard body temperature. Normal human body temperature is 36.9 ° C at the armpit temperature, and children are slightly higher than adults and tend to be lower in the elderly.
Body temperature can vary depending on the body part and may vary depending on the measurement method. For example, the oral temperature when a healthy person is in a stable state may be 0.6 [deg.] C below the rectum temperature, and the armpit temperature may be 0.2 [deg.] C lower than the oral temperature. There is also a variation between days, which may be lowest at 46 o'clock in the morning and highest at 68 o'clock in the evening, and the difference may be within 1.0 ° C.
Body temperature plays a major role in checking your body's health. Therefore, it is possible to check the approximate health condition just by writing a thermometer well. However, it is cumbersome to use a thermometer every time you check your health condition, and if you do not use the thermometer correctly, you may experience errors in your body temperature measurement.
