Four IR Sensor Based Automatic Control of Railway Gate using Microcontroller

This paper investigates based on four IR sensor automatic control of railway gate using a microcontroller system. There are so many railway accidents happening due to the carelessness in manual operations or lack of worker. So, this paper describes four IR sensor based automatic control of railway gate system for saving precious human lives and preventing major disasters in railway track. Railway gate may be saved for the road users to prevent accidents in terms of train speed at a level crossing. Automatic railway gate control system is an innovative circuit which automatically controls the operation of railway gates detecting the arrival and departure of train at the gate. This automatic system can be replaced by the gates operated by the gatekeeper. The operation using Arduino UNO that integrated with other circuits involved such as power supply, IR sensors, light indicators, buzzer, and gate motors. The servo motor is used to control the open and close status of the railway crossing gate. The four IR sensors are placed on the railway tracks. The gate is closed when the first one senses the train and is opened when the second one senses the train. This operation is performed when the train is coming from the left side of the gate. When the train is coming from the right side, the third and fourth sensors is performed in the same operation. The red LED is HIGH when the gate is closed and the green LED is HIGH when the gate is opened. This system is based on software programming to operate the hardware structure. Program for four IR sensor based automatic control of railway gate system is based on Arduino UNO with C language. The main function of the design is Arduino UNO.
