Introduction

The railroad crossing is one of the most critical components in the railroad transportation infrastructure. Unfortunately, in many intersections, there are still often traffic accidents due to the lack of adequate facilities and negligence of guard officers. To overcome this problem, an automatic railroad crossing door crossing system is needed that can operate independently. This system will function to maintain the safety of road users and train passengers. In this article, we will discuss the design of a miniature automatic railroad door cross based on the microcontroller ATMEGA 8535.

The Importance of Railroad Crossing Safety

Railroad crossing safety is a critical issue that requires immediate attention. According to statistics, there are thousands of accidents that occur at railroad crossings every year, resulting in injuries and fatalities. These accidents are often caused by the lack of adequate facilities, such as warning signs, signals, and gates. In addition, the negligence of guard officers can also contribute to these accidents. Therefore, it is essential to develop an automatic railroad crossing door crossing system that can operate independently and maintain the safety of road users and train passengers.

The Main Component of the System

This automatic railroad crossing door crossing system has three main components:

1. Servo Motor

The servo motor is a crucial component of the system, as it serves to move the doorstop, open and close it according to the railroad traffic conditions. The servo motor will rotate automatically based on the command from the microcontroller. The servo motor is a type of motor that uses a feedback loop to control its position and speed. In this system, the servo motor is used to open and close the doorstop, ensuring that the door is properly aligned with the train.

2. Line Sensor

The line sensor is another critical component of the system, as it serves as a detection of the existence of a train. The combination of infrared sensors and photodiodes is used to detect the train approaching. When the line sensor detects the existence of a train, it will give a signal to the microcontroller, which will then issue orders to the servo motor to close the doorstop.

3. Microcontroller ATMEGA 8535

The microcontroller ATMEGA 8535 is the "brain" of the entire system. This microcontroller will process data from the sensor and control the servo motor and the sound module based on the specified programming logic. The microcontroller is a type of computer chip that is used to control and process data in electronic systems. In this system, the microcontroller is used to control the servo motor, sound module, and display on the LCD.

How the System Works

The system works as follows:

When the line sensor detects the existence of a train that will pass, the microcontroller will immediately give orders to the servo motor to close the doorstop. At the same time, the voice module will be active, giving a warning that the train will pass, and the display on the LCD will show the message "The train will pass".
After the train passes, the line sensor again gives a signal to the microcontroller. The microcontroller will then issue orders to open the doorstop, turn off the sound module, and change messages on the LCD to "goodbye".

System Testing

In the final stage of testing, the results show that the line sensor is able to detect trains that pass accurately. In addition, the servo motor functions well in opening and closing the doorstop according to the program that has been written using Codevision AVR. This result indicates that the automatic railroad crossing door crossing system has been running as expected.

Conclusion

The design of the Autmega 8535 Microcontroller Railroad Based Railroad crossing not only increases safety at the railroad crossing, but also provides innovative solutions to the problem of traffic accidents that often occur. With the application of this automation technology, it is expected to reduce the risk of accidents and provide comfort for road users and train passengers. In the future, further development of this system can be done to increase effectiveness and efficiency in maintaining transportation safety.
