Surveillance Rover to Maintain Social Distancing in Crowded Areas

COVID-19 is making a huge impact both in terms of the economy and human lives. Many lost their lives due to COVID-19 which is found in most of the nations. The number of positive symptoms is increasing rapidly all over the world. To safeguard us from the virus, some protocols have been addressed by WHO in which people has to wear a mask and make a social distancing when moved in public. Therefore, social distancing places an important role in preventing us from the spread of the diseases. The minimum distance between to be maintained is informed at 6 feet informed by the health organizations. When people gathered on a group social distancing could not be maintained even if manual or any kind of technology implemented. Temperature measurement on mass gathering was also a tedious process where the monitoring is essential. Multiple methods such as thermal cameras, temperature sensors for monitoring the personnel has not been efficient. In the proposed work to monitor the social distancing between the persons an ultrasonic sensor is placed to detect the obstacle and an IR sensor to make the rover move. An encoder is used to calculate the distance based on the rpm of the wheel. Based on this input the distance is checked within this limit the obstacle is detected, an alert signal is made using the buzzer. A thermal sensor is used to measure the temperature of the person and an LCD display shows the temperature of the person and distance between obstacles. The proposed system has resulted in identifying the distance and helps in reducing the spread during the pandemic situation. © 2023 IEEE.

Design of IMC Based PI Controllers for Three Tank Interacting Level Control Process

India is a country that consists of most process industries, where most of the end products are related to water or other liquid state materials. In recent days pharmaceutical industries have grown on a larger scale due to the COVID'19 situation. One of the major processes is to maintain the level of the liquid for having a continuous process. In this proposed process, Proportional Integral (PI), Internal Model Controller (IMC) based PI is implemented on a three-tank integrating system with two input and two output (TITO). IMC-PI gain values are acquired and decoupled using the decoupler matrix by determining RHP poles and zeros for the TITO system. Since two input tanks are involved, therefore two different gain values are calculated keep the liquid at the given level. The proposed system has given has resulted with 180 seconds and 190 seconds for Settling time and 5% and 0% of Overshoot for two tanks. © 2022 IEEE.
