We usually end up waiting in queues at various places, from passport renewals to shopping malls. Managing queues can be a tough task at places where queues move slowly like security check queue. A separate person needs to be deployed to ask a person to go and the net person to stop and wait his/her turn.
Well we here automate this task by developing a system that automates this task using Led display and electronics controller circuitry. The system is designed to automatically handle queues without needing a separate person to ask people next in line to stop or Go.
The Stop can Go System provides the following advantages:
- Automatic Person Detection
- LED display for Stopping and Go Indication with Buzzer
- Red Color Stop and Green Colored Go Indicator LED
The system is made using an STM32 controller along with an Ultrasonic sensor for person detection, RGB LED display for displaying STOP/GO, a keypad for operating the indication and a buzzer with some electronics components and PCB board. The system when turned on allows the admin or queue manager person to operate the system using keypad. The person has access to button near him. Once the admin has cleared the current person to go he presses the go button.
The system now displays go on the LED display in Green and monitors ultrasonic sensor. As soon as 1 person has passed in front of the sensor, it instantly shows stop display in red so that only one person is allowed and next person stops. This system repeats each time the button is pressed by the admin. This automates the entire stop and go process in queues and has a lot of applications.
