THE GERMICIDE HATCH

Project Title

THE GERMICIDE HATCH

Project Area of Specialization Mechatronics EngineeringProject Summary

Since December 2019 there were reported unexplained cases of pneumonia in Wuhan, China. After researches WHO formally named the disease coronavirus disease 2019 (COVID-19). In this research we see that the ratio of male to female deaths are 3.25:1 and the median age of death was 75 years, it is recorded that the median time from early symptoms to death is 14 days. As a measure of hygiene and safety measures, most people wash their hands, and they do so regularly nowadays due to the obvious COVID-19 pandemic. The current need of the time was to introduce a safety gizmo that could help us in fighting and detecting coronavirus so that economy of our country could not be further more damaged. We started designing a walkthrough gate named (The Germicide Hatch), this project is designed to prevent the spread of coronavirus. Here in this project, we have set such sensors that check the body temperature, mask detection, and touchless hand sanitizing process. The door does not unlock until all the tasks were not completed. This walk-through is implemented in many of the places in the city and it has a direct and immediate impact to prevent the spreading of the coronavirus. It should be used in many of the hospitals, schools, shopping malls, offices, gyms, supermarkets and also in other busy places.

Project Objectives

The aims and objectives that were to achieve after the accomplishment of the task were to get a compact gizmo that will perform thermal checking, mask detection, and automatic hand sanitizing. The other core objective is to reduce the spread of the virus as soon as possible. Areas where a huge amount of workforce is required and their safety is necessary, this will automatically check for the victims of covid- 19, allow them to enter the respected areas considering the sops into account. By the implementation of this gizmo in rush areas, reduction of coronavirus and other viral infectious viruses will be assured as most viral infectious viruses mainly start with a temperature rise so in order to tackle that down, a thermal scanner is installed which will check for the patient's temperature. It also has a camera for the detection of masks so that spread of the virus could be made much more impossible as the mask stops most of the particles that came out from the mouth. This gizmo is specially designed to prevent the spread of coronavirus as it is completing multiple tasks within a very short time it checks the temperature, mask detection, and also automatic hand sanitization. It covers many SDGs like good health, economic growth, innovation, and infrastructure.

Project Implementation Method

There will be a total number of four checkup procedures for the entrance. First of all, the door will be locked. Suppose the client has fixed the number of people to be allowed inside the vicinity is five persons at a time. Firstly the system will check how many persons are already inside the vicinity. If the number of persons inside the vicinity is less than 5, the system will proceed to the next procedure. If the number of counted persons inside is5, then the system will tell the customer to please wait a while. After the system count, the next procedure will be a thermal check-up. The rack and pinion mechanism will drop the thermal gun down from the top of the door. The thermal gun will have an ultrasonic echolocation sensor. The thermal gun will be descending down slowly, as the ultrasonic echolocation sensor will sense the forehead of the customer, it will stop there and the thermal gun will operate then. The thermal gun will detect the temperature of the customer. If the thermal check-up will show a reading of a person more than 99°F, the system will not allow the person to enter, hence not proceeding to the next procedure. If the thermal check-up shows the reading of normal human temperature, then the system will proceed to the next procedure. The next procedure will be mask detection. There is a camera attached below the thermal gun mechanism. After this, the camera will operate and sense the mask of the person by image processing. The camera will process the face of the customer in real-time and detect the mask over it. The mask could be of any color, so we have created a long and detailed data set to make our processor judgment easier and smoother. If the system doesn’t detect the mask over the customer's face, it won’t allow them to enter and will not proceed to the next procedure. Then the em will ask the customer to sanitize their hand. For this procedure, an automatic sanitizer is installed into the door. The automatic sanitizer operates with the help of an ultrasonic sensor and solenoid valve. As the person will put his hand before the ultrasonic sensor, the sensor will sense it and give the command to the solenoid valve to operate. Then the solenoid valve will operate and drop the sanitizer into the hand of the customer. By this procedure, the person will sanitize his/her hand without any physical contact. After the sanitization, the system will ask the customer to “press the lock button to enter”. As the person will press the lock button, the door will be unlocked and the system will count an addition in the previous number of persons inside the vicinity. As the person will enter inside the vicinity, the door will shut back and will get locked automatically. Then for the next person, the same procedure will be followed.

For the exit procedure, there will be a button with the handle. When the person will push the button, all entrance codes will be overridden and the gate will be unlocked and the system will decrease a count in the counter mechanism.

Benefits of the Project

Primarily after the occurrence of the lockdown, a major loss in the economy was observed soon after smart lockdowns were taken off by the government of Pakistan. To check whether the sops are taken into consideration in malls was not a child’s play. It was obvious that human errors were possible which is why it was decided to develop a system that could help us in identifying the victims of COVID-19 and ensure the safety of the staff members and other customers in the mall, offices, and other workplaces which are mostly rush areas. Areas where a huge amount of workforce is required and their safety is necessary, this will automatically check for the victims of covid-19, allow them to enter the respected areas considering the sops into account. The system (door) that is going to be made will have sensors and camera which will count and check for the customer’s mask (by image processing), according to which a customer will be allowed to enter the mall, the thermal sensor will check for the customer’s temperature and if zero possibility for covid-19 is observed only then the customer will be allowed to enter the respected area. This model was proposed specifically because gates are everywhere and these are the prior source for the entrance and exit from a space or place. An ultimate fast and compact solution by which the continual of malls and offices can be assured but also reduce the spread of COVID- 19. Ensuring the safety of the people around this model was proposed in order to help people get to their workplaces daily and run their livelihood. The core focus was to resume and unblock ways that were blocked by the lockdowns for the common people which are hand to mouth and run their livelihood on daily wages. With the help of this gizmo health and safety with resuming the work environment will be assured.

Technical Details of Final Deliverable

Our project will be able to perform various tasks in a serial manner to help prevent the spread of deadly coronavirus. As we know we are under the chaos of coronavirus, which has affected our daily lives. After the production, the final deliverable of our project would be as followed:

First, the sensors will detect the forehead of the person, by adjusting its height with the assistant of a rack and pinion gear mechanism. Then the thermal sensor will detect the temperature of the person. After the thermal check-up, the camera will detect the mask of the person, whether the person is wearing the mask or not. After satisfying these conditions, the system will ask the person to sanitize their hands, with our automatic sanitizer. After all these procedures, the person will press the enter button, which will unlock the gate and will count an increment in the person counter. If the maximum number of the on entered will be reached, the gate will be locked until someone leaves, therefore controlling the crowd and promoting social distancing.
