TRAIN DETECTION AND ALARM SYSTEM
The Portable Train Detection and Alarm System (POTA) is specifically designed to ensure the safety of railway workers performing maintenance on bridges and tracks. The system detects an approaching train and sends a signal to a receiver unit equipped with a siren. This siren alerts workers in advance, giving them sufficient time to vacate the tracks and ensure a safe working environment.
THERE ARE TWO IMPORTANT PARTS OF THE SYSTEM
Transmitter
- It consists of a power supply (solar panel , solar charge controller and battery).
- Radar sensor is used to detect trains at a specific distance from the track.
- RF module is used to transmit data from the transmitter, converting it into a signal that can be received by the receiver.
- Structure is also constructed to install this device.
RECEIVER
- It consists of a power supply (solar panel , solar charge controller and battery).
- RF module is used to collect data from the transmitter.
- Hooter is used to sound a siren before a train arriving a bridge or any other construction site.
- Structure is also constructed to install this device.
WORKING
- A structure is developed for mounting the device. Then, one by one, all necessary parts are installed at the receiver and transmitter ends. The transmitter is located 1.2 km away from the receiver end on both the up and down sides of the train track.
- When a train passes through the transmitter end, the radar sensor detects it and transfers the signal to the receiver end. The receiver end collects this data, reads it frequently, and activates the hooter, sounding an alarm at railway bridge. This alerts people to pay attention when they hear the siren.
