Description

Non-face-to-face smart access control system to prevent the spread of viruses and diseases

The present invention relates to an access control system, and more particularly, to a non-face-to-face smart access control system that measures a person's body temperature in real time and determines whether or not to wear a mask through face recognition to prevent the spread of viruses and diseases.

In general, when a patient or an infected person with an infectious disease moves freely in a public place or large building where many people gather, the disease can be transmitted to others, and in particular, the disease can be spread widely.

Therefore, these infected people should be quarantined from the public at an early stage to prevent the possibility of transmission to multiple people.

Recently, a new respiratory infectious disease occurs, and dangerous situations that can infect a wide range of people frequently occur. For example, new infectious diseases such as Corona (COVID-19), SARS (severe acute respiratory syndrome), swine flu, Ebola, and MERS are occurring frequently.

However, since these contagious diseases show symptoms similar to common diseases such as colds, it is difficult for the infected person to know the infection itself until the contagious disease is confirmed. Therefore, it is necessary to quickly check whether these infected people pass in public places where many people gather, and take additional tests or quarantine measures.

Most of these contagious diseases accompany fever, so people with severe fever can first be judged as suspected of the disease, and whether or not infected can be determined through close examination. That is, the primary suspect can be determined by measuring the body temperature.

Body temperature refers to the temperature inside the body. Although body temperature varies greatly depending on the body part, the normal body temperature of humans is 369 ° C under the armpit, and children tend to be slightly higher than adults, and the elderly tend to be lower. The hot state of body temperature causes a more serious situation than the cold state. The normal body temperature for adults is about 37℃, but at about 41℃ it causes cramps and pain, and 433℃ is the maximum limit for maintaining life. In addition, it cannot sustain life even at a body temperature of 27°C or lower.

The most accurate way to measure body temperature is to measure the rectal temperature measured at a point more than 6 cm from the anus. However, because the measurement method is too complex, the attributive temperature is usually measured. However, since an unspecified number of people pass through public places such as airports, it takes a lot of manpower to measure the return temperature of all passers-by and check their body temperature, causing inconvenience to passers-by. have.

In order to solve the above problems, various devices have been proposed for monitoring body temperature and the status of an infected person using a non-contact facial recognition body temperature measuring device. However, since these devices have a limited camera field of view because the position of the camera is fixed, it is inconvenient to adjust the camera angle each time according to a person's height, and there is a problem that it takes a lot of time to measure body temperature.

The present invention has been devised to solve the problems of the prior art, and at the same time confirming the identity of the entrant and automatically adjusting the position of the camera using the driving unit, it is easy to measure the body temperature regardless of a person's height and precisely the body temperature of the entrant Its purpose is to be able to measure
