High Speed Railway Crossing Gate Closing System
A Large Railway company was looking to implement a backup system for a railway crossing that would actuate the closing of the gates if the main system failed.
The system had to detect the presence of the train a few kilometers away from the railway crossing and then relay this information to the gate actuator at the base controller. The stringent requirements for a very fast link up time, range and narrowed down the choice of radios to the DNT900
A DNT900 radio was integrated with the sensor circuitry that was used to detect the presence of a passing training. This information was then relayed back to another DNT radio embedded into the main gate controller circuit located a few km away. Having received the information of an oncoming train, the gate controller circuit now had information to close the gate in case of failure of the main system.
Applicable Product Features
The DNT900’s fast link up times, high power, ability to transmit over long distances reliably and API designed for easy system integration made this the radio module of choice for this application.
