Project Name : Train Anti Collision Device
Theme Name : Disaster Management
The TACD (Train Anti Collision device) is a safety device to prevent train collisions. The main components of the device are the LDR (Light Dependent Resistor) and Laser which are easily available sturdy and economical too. In addition to the LDRs and lasers, the devices are also fitted with a buzzer alarm and an LCD screen to alert the loco pilot and apprise him of the current status of the train. The moment the laser beam of train falls on the LDR of the opposite train, the device becomes functional and applies the automatic emergency brakes, bringing the train to a halt. A similar arrangement helps in avoiding of overshooting of train signals. Every train when fitted with the TACD is safe from collisions occurring due to overshooting of signals. Rear-end and head-on collisions too can be successfully prevented.
Our device is superior to the existing devices base on GPS as they rule out the risk of sabotage by terrorists. Our device is sabotage – free and more economical than the existing devices!
