Electronics and communication engineering is the engineering domain that deals with electronically operated circuits and systems. Electronics & Communication ProjectsGlobal Navigation Satellite System (GNSS) receivers use radio signals from. This project is done with Aim towards addressing the issue by developing an automatic Railway track detection system integrating an infrared IR crack Sensing module based on GSM technology by which information about the location of the crack can be conveyed to the central Location enabling immediate. Top electronics and communication projects for engineering students, researchers and engineers.Automatic Railway Gate Control System Using Arduino & IR SensorAbout a million people have died over the past 5 years in unmanned railway crossings all over the world. Nevonprojects helps you explore this field with innovative electronics projects ideas. Railway track crack detection system project report 16.
Four IR sensors are used for sensing the arrival or departure of train. Two Servo motors are used to open and close the railway gates. You may take it as a onetime investment.The Automatic Railway Gate Control System Project makes use of an Arduino Nano to control the whole circuit. This project will not only make the system more reliable & precise, but also save the authorities from hiring man power to do the job. The Automatic Railway Gate Control System using IR Sensor & Arduino focuses on systematic traffic control of railway gates that are both manned and unmanned. Os9 68k emulator mac macos dsk imageThe other two PCB’s are needed for the IR pairs. One is for the Arduino Nano, which works as controller of the whole project. Components Used ComponentsAutomatic Railway Gate Control System Using Microcontroller – CircuitThe automatic railway gate control makes use of 3 PCB’s. As soon as the train moves further away from the railway crossing, the gates must automatically open to allow vehicles to cross by. Stabile gamecube emulator macServos are controlled by sending an electrical pulse of variable width, or pulse width modulation (PWM), through the control wire.IR pair is made with dual Op-amp IC LM358. These pins are connected to the Servo motor. IR Pair using LM358 Op-AmpAutomatic Railway Gate Control – Circuit DiagramOutput of all the sensors are connected to A0, A1, A2 and A3 pins of Arduino.The pins D9 and D10 of the Arduino are PWM pins. Automatic Railway Gate Control – PCB Design for Arduino NanoAutomatic Railway Gate Control System Project – PCB Design for IR Sensor PairIf you want to make the circuit on zero PCB or breadboard refer both the figures given below. If you want to make etched PCB, refer both the figures given below. All the sensors are connected to Arduino. Working Automatic Railway Gate Control SystemFour sensors are used in the project as two pairs of two sensors these sensors are kept in the both side of level crossings gate as shown in Fig 1. IR ConnectionIf you are using ready-made IR sensors please replace “” and “>” into “<” in the code, because output of ready-made IR sensor is invert of the sensor pair used in the project. If you are familiar with PCB etching you can etch the PCB, but it is not necessary to use the etched PCB, you can use two IR sensors instead of one pair that is easily available in market. IR SensorsTwo IR pairs are used in the project. A preset is used for calibration. Railway Track Detection System Project Report Driver IC OrOverview of Control SystemThere are two presets in an IR pair circuit. Servo motor receives the PWM signal from Arduino and rotates the motor at fixed angle according to duty cycle of signal. The first pin is PWM, second is Vcc and third is GND. Servo motor has three pins. When train departure from any side it first cross the sensor2 after that cross the sensors, in this way Arduino open the gate.Servomotors are used in the gate because it is very easy to use and does not require any driver IC or circuit. After that, four sensors are declared named “sensor1”, “sensor2”, “sensor3” and “sensor4” are used to connect Arduino after it an integer is declared by name buzzer.In the void setup section both the servo motors are attached by function “myservo1.attach (5)” in this function 5 is the pin number. In the project, two servomotors are used so in the fourth and fifth line two servomotors are defined named myservo1 and myservo2.Now some integers are declared, “pos” is the position integer for servo. For increasing, the speed of opening and closing decrease the delay in line 71, 73, 84 and 86.In the code two libraries “EEPROM.h” and “Servo.h” are defined. VideoIn the video, the speed of closing & opening of gate is slow, so it would be better if you will use the slow train. This calibration procedure has to be done for all the sensors. When some barrier is placed between LED and Photo diodes, indicator LED starts glowing. This same approach is used for sensor3 and sensor3.Another “if” loop is used in line 48 and it become true when value of EEPROM(0) is Zero and EEPROM(1) is One. Now a while loop is used when train come and cross the senaor1 system come in this loop, after that an if is used when train cross the senaor2, EEPROM (0) and EEPROM(1) are updated by one. Now EEPROM.write(0,0) function is used to write EEPROM of Arduino.In the void loop section if condition is used, When value in EEPROM address1 and address2 is become zero, system come in if loop. Buzzer is declared as Output device using function “pinMode(buzzer,OUTPUT)”. ![]()
