AT89S51 Microcontroller-Based Railroad Automatic Door Railroads Using Assembly Language

Introduction

The safety of railroad crossings is a pressing concern due to the limitations of human supervision in overseeing train traffic. The consequences of accidents caused by the weakness of the supervisory system in the railroad crossing path are a stark reminder of this problem. To address this issue, a system that can detect the presence of trains and automatically close the crossing doorstop is essential in increasing safety and preventing accidents.

Background

The development of an automatic railroad crossing model based on the AT89S51 microcontroller is a significant step towards improving the safety and smoothness of traffic at railroad crossings. This model is designed to mimic the actual condition of the railroad crossing and is expected to be applied in the field. The system utilizes photodiode and infrared LEDs as a sensor to detect passing trains. When the sensor detects the train, the AT89S51 microcontroller will immediately send a signal to close the crossing door bar.

How Automatic Door Cross System Works

The automatic door cross system works by utilizing photodiode sensors and infrared LEDs that are placed on the railroad track. When the train passes, the infrared light from the LED will be blocked by the train and captured by the photodiode. The photodiode sensor then sends a signal to the AT89S51 microcontroller. The AT89S51 microcontroller, which has been programmed in assembly language, will process the signal and provide commands to close the doorstop.

System Components

Photodiode Sensors: These sensors are used to detect the presence of trains by capturing the infrared light blocked by the train.
Infrared LEDs: These LEDs emit infrared light that is blocked by the train, allowing the photodiode sensor to detect the train's presence.
AT89S51 Microcontroller: This microcontroller processes the signal from the photodiode sensor and provides commands to close the doorstop.
Doorstop: This is the mechanism that closes the crossing door when the train passes.

System Operation

The photodiode sensor detects the infrared light blocked by the train.
The photodiode sensor sends a signal to the AT89S51 microcontroller.
The AT89S51 microcontroller processes the signal and provides commands to close the doorstop.
The doorstop closes, preventing accidents caused by human negligence.

Advantages of Automatic Door Cross System

The automatic door cross system has several advantages, including:

*** Increasing Security: ** This system automatically closes the doorstop when the train passes, thus preventing accidents caused by human negligence. *** Efficiency: ** This system works automatically, so it does not require continuous human supervision. *** Increasing the Smooth Running of Traffic: ** This system ensures that the doorstop will only be closed when the train passes, so that it does not interfere with the smooth traffic.

Implementation in the Field

The automatic railroad crossing model can be implemented in the field with several modifications. One way is to use a stronger driving motor to move a larger doorstop. In addition, this system can also be equipped with additional features such as alarm and warning lights to improve security.

Modifications

Stronger Driving Motor: This modification will allow the doorstop to be moved more efficiently and effectively.
Alarm and Warning Lights: These features will improve security by alerting road users of the presence of trains.

Conclusion

The development of the AT89S51 Microcontroller Automatic Railroad crossing model is an effective solution to improve the safety and smoothness of traffic at the railroad crossing. This system can be implemented in the field with several modifications to improve its functionality and reliability. Thus, this system can make a significant contribution in minimizing the risk of accidents at railroad crossings and improving safety for road users.

Future Work

Future work on this project can include:

Improving the Accuracy of the System: This can be achieved by using more advanced sensors and algorithms to improve the accuracy of the system.
Increasing the Speed of the System: This can be achieved by using faster microcontrollers and more efficient algorithms to improve the speed of the system.
Adding Additional Features: This can include adding features such as alarm and warning lights to improve security and alert road users of the presence of trains.
