Abstract

Level crossings are critical for ensuring the safety of long-distance railway operations. To maintain the reliability of these at-grade crossings, their power supply systems are equipped with lead-acid batteries. This study focuses on the battery charging system. A known effect of battery charging is temperature rise due to charge current flow. The Constant Current-Constant Voltage (CC-CV) method is proposed in this research to address the issue of prolonged charging time while monitoring temperature to preserve battery health. Battery charging tests were conducted by comparing the CC-CV and Switch Mode Power Supply (SMPS) methods, starting from the minimum battery voltage (11.7 V) until the voltage set point was reached. The results show that the SMPS method required 5 hours with an average charging temperature of 34.0°C. In contrast, the CC-CV method required only 2.1 hours with an average temperature of 35.4°C. Therefore, the CC-CV method can significantly accelerate the charging time while ensuring the temperature remains within the specified maximum limit. This shorter charging duration is expected to enhance the reliability and prevent service disruptions at level crossings.

Abstract

This study evaluates the feasibility of a microcontroller-based Supervisory Control and Data Acquisition (SCADA) prototype for railway traction substation monitoring. A quantitative evaluative approach is employed using experimental data, focusing on reliability, response time, accuracy, and communication performance. The system integrates Arduino-based controllers, electrical sensors, TCP/IP communication, and a computer-based Human Machine Interface (HMI). Results show that the system achieves an operational success rate above 90% with an average response time below 2 seconds, indicating adequate performance for basic monitoring and control functions. However, compared to industrial SCADA standards, the system exhibits limitations in reliability, security, and scalability. Therefore, the prototype is classified as having limited feasibility, suitable for educational and simulation purposes but not for direct operational deployment. This study provides a structured evaluation framework and highlights key gaps for future development of more robust SCADA systems. This study contributes by introducing a quantitative feasibility evaluation framework for low-cost SCADA systems in railway applications.
