Development of Crowd Management System using FPGA Circuits

This paper aims to develop a crowd management system in localities where mass gathering of people is observed frequently. We employ two ultrasonic sensors to track the number of people entering and leaving the room. This system is designed in a mode that if the number of people in the room exceeds the allowed limit, a buzzer will go off and alert the event management/security. The number of people will be displayed in the seven-segment display provided in the Basys-3 board by interfacing the ultrasonic sensors with the Basys-3 board. This crowd management system contains red and green LEDs which indicate whether the person is permitted or not. The red LED indicates that the person is not permitted to enter the room as the room is at its maximum capacity and the green LED indicates that the person is permitted to enter the room.
