A SYSTEM AND A METHOD FOR CONTACTLESS THERMAL DETECTION FIELD OF THE INVENTION

The present disclosure relates to thermal scanning systems.More specifically, the present disclosure relates toa system and a method for contactless thermal detection.

BACKGROUND OF THE INVENTION

In this COVID-19 pandemic situation offices, schools, malls and colleges are facing lots of difficulties. To deal with the situation with the possible measures to reduce the spreading of the COVID-19 it is required to implement strong protective measures while trying to keep the economy going. According to world health organization some of most common ways to protect ourselves from COVID-19 includes taking care in your workplaces, taking care of physical distancing, taking care to spread the word not the virus, considering for health before opening the workplace, proper sanitization, self-care, and the like.

Currently, most common and preferable ways to prevent spreading of virus is proper screening and thereafter taking proper precautions if something went wrong. But,during the time of screening, one who is checking the temperature of every personmay get affected by the virus, and this can also lead to more spread of virus. While screening someone who is already affected by virus may affects the person who is screening which results in spreading of virus to another person. Therefore,it is required to find the alternative for screening contactless by a solution that is contactless thermal detection which is made with all the safety measures for the organization or any public places to perform screening ofbody temperature.

In one solution, a balance infrared thermometer and method for measuring temperature is provided. A sensor includes two thermal energy detectors thermally insulated from one another. The first detector is warmed or cooled by radiation between it and the object being measured. The second detector is warmed or cooled by exchange of thermal energy with a thermal reference source until the second detector reaches a temperature that is a predetermined ratio with that of the first detector. A control circuit which receives signals from the detectors that represent their temperatures, provides control for the thermal reference. A third detector measures the temperature of the thermal reference source and provides a signal representative of the temperature of the reference source. A processor receives the signal from the third detector and provides a signal indicative of the temperature of the object.

In one solution, a multi-site infrared thermometer is provided. An infrared thermometer includes a probe and an infrared sensor. The probe with an infrared target absorbs thermal radiation to provide a substantially consistent source of infrared radiation and an aperture for preventing contamination of the infrared target while permitting the transmission of thermal radiation to the target. The infrared sensor is configured for sensing infrared radiation from the infrared target. The infrared target is positioned within the probe such that it absorbs thermal radiation that comes from the aperture and thereafter emits thermal radiation to the infrared sensor.

However, several body temperature scannersare available in the market for screening the body temperature, but the existing solutions are dangerous as it requires human involvement which may result in spreading of the virus. In view of the foregoing discussion, there exists a need to have a system and a method for contactless thermal detection.

In an embodiment, the system aims to achieve below given goals. All these goals are really important in the view of COVID-19. After successful implementation it is aimed to have a system which will be capable of detecting the temperature on contactless basis which will increase the efficiency of the system and will help more people to get checked at one time without affecting anyone. It has been tried to write down the situations and their claims through the system, how to solve the problem with the system. In contactless temperature detection, now in the COVID-19 scenario where everything is getting contactless then how can anyone make someone stand to check other's temperature with proper contact.

In an embodiment, to avoid contact while checking the body temperature in schools and offices or anywhere where someone checks persons manually. With the help of this system no one will get in contact with anyone while checking the temperature as the system is totally automatic There is no need for anyone to let the system operate.Most importantly there will be no need of anyone to operate, so that will help in contactless temperature measurement and auto height adjustment. In low cost and easy to install, as this time everyone is going through lack of money. So, everything should be planned in budget to fight with COVID. So, here it requires a system which is cost effective.

In an embodiment, thesystem is divided into many modules so it is easy to install in any large sized or small sized organization according to the need. Like if some organization only wants an automatic size changer module then they can only take that part and implement that. With this it is using very cheap sensors which make it low cost.

In an embodiment, ease to use for even playgroup students or illiterate workers is one of the major problems which is system should not be too tough to operate it has to be assured that there should not need any technical knowledge while operating the system. As thesystem is having fully automated feature.So, this makes it easy to use, that's why a person with zero technical knowledge or even a child can easily go through this. While designing the system what to be focused most is the ease in working with so this is planned totally automatic and easy to manage. So, this is having total automatic features like auto height adjustment, auto save of data, auto alert system, face recognition and many more.

In an embodiment, as it is known that there may be anyone to be checked in terms of temperature so it is to be kept in mind that system can be used by anyone can say a person having small height or a person very tall both will be need to check for the temperature. So, it is necessary that the system must be automatically height adjustment. So, keeping all this in mind fully automatic height adjustment system is designed. A module which makes thermal sensors 108 useful for all aged or all sized people is implemented. As it is known that everyone doesn't have the same height so in that case the user has to adjust their height by themselves if the system is not automatic height adjustment so automatic height adjustmentsystem is designed which makes it more effective and contactless.

In an embodiment, keeping everyone's record is not an easy task for anyone. So,system should be totally automatic in terms of storing records so that they can be analyzed after if needed. Thesystem keeps record of each and every person passing through it. For this some prerecorded faces are used. If the system doesn't have that record then it creates the one automatically and adds the entry of that person properly in the database.It is also important to keep the system energy efficient so that it should not be a burden on pockets.

In an embodiment, the system is energy efficient as the system is implemented in such a way that if the system is not in use then it will not consume a single watt of electricity which makes it energy efficient. In am embodiment, estimated cost of the system, as it isstated earlier that system is cost efficient because of its modules. Each module is independent, so it is not necessary to implement all the modules at once, the user can use them according to their need and budget. An estimated cost of every module are temperature detection module 110 of 1000 INR, automatic height adjustment module 104 with thermal detection of 1700 INR, face detection and data saving module 116 of 2000 INR (HOSTING AND STORAGE ACCORDING USER NEED), and barricade module 120 of 700 INR.So,the estimated price of the system is Rs. 5000INR.

In an embodiment, it is concluded that in this COVID-19 pandemic situation offices are partially opened and schools and colleges are about to open. So,the system is designed to face the situation with the possible measures for reducing the spreading of the COVID-19 and to move on by implementing strong protective measures while trying to keep the economy going.It is known that the measure factor which affects a COVID-19 positive patient is temperature, so it is required to do proper screening of every person while letting them go in some places like malls, schools or offices. So, it is too necessary. Keeping this in mind a contactless method which can be provided by the system is designed.

In an embodiment, a person may be assigned to check temperature but that is not the safe way to test because the one who tests will have to get in contact with everyone whom he is going to test, so it's never safe for anyone. To overcome this, the disclosed solution of a fully automatic thermal detection device is designed which can help to easily and safely detect the temperature of everyone and this system will also have some useful features like auto height adjustment and data storing that features will help this system to be more effective.So, in that case the system is very effective. As the system is configured keeping every age person in mind so it will be helpful and efficient for everyone.

In an embodiment, aim of the system includes contactless temperature detection, low cost and easy to install, easy to use for even playgroup students or illiterate workers, automatic height adjustmentthermal sensors 108, proper database record of everyone, face recognition and auto storing the pre saved faces, new record for guest employees or visitors, energy efficient, as the system will be active only when someone passes through the frame 102, time saving, and system will let someone enter by the gate only if his temperature will be below the COVID-19 standards and will inform this to respected authorities.

In an embodiment, the disclosed systemis structured just like a metal detector in shopping malls and will have one thermal detection sensor which adjusts height automatically according to the height of the person passing through the frame 102. The system will have one barricade 120 which will only be open if someone has the temperature between the standards of COVID 19. The system will also be storing the temperature and photo of everyone passing through and if the photo will be already in record then the temperature will be added to previous record of if system doesn't have the face earlier saved then that face will be added to the system.So, the disclosedsystem is totally automatic and there will be no need to touch the system and there will be less chances of spreading of the virus while screening.

The system developed in accordance with the present disclosure are improved at developing a methodfor contactless thermal detection. The system facilitateseasy installation and user-friendly system. The disclosed system providesface recognition and auto storing ofimage/video along with body temperature.The disclosed system providesa system which is activated only on presence of any person. The disclosed system providesautomatic systemthat does not required any physical contact for temperature screening.Yet, the disclosed system delivers an expeditious and cost-effective method for contactless thermal detection.
