Iran Sardar's Innovative Solution to Metro Rail Bearing Pad Safety Risk

The safety of pedestrians in the capital has come under scrutiny following the tragic death of a person after a metro rail bearing pad fell on the street. To address concerns regarding metro rail structure safety, Iran Sardar, a student from Daffodil International University, has developed an innovative technology to detect potential risks in the bearing pads of metro rails.

On October 26, at around 12:20 PM, a bearing pad from the 433rd pillar of the metro rail in the Farmgate area fell onto the street, fatally injuring pedestrian Abul Kalam Azad (35). Earlier, on September 18, 2024, a similar incident occurred when a bearing pad from the 430th pillar fell, although no casualties were reported at that time.

The Problem
The bearing pads, crucial for stabilizing the metro rail viaduct, can shift over time due to prolonged use or excessive vibration. After the recent incidents, the metro rail authorities have installed CCTV cameras on the pillars but have yet to implement an automated system for detecting such shifts.

Innovative Safety Technology
In response to this, Iran Sardar has developed a "Metro Rail Bearing Pad Safety Monitoring System" designed to address the issue of bearing pad displacement. His system uses sensors installed on the pads to monitor and detect any structural deviations in real time.

According to Iran Sardar, "Any vibration or shift in the bearing pad will be immediately detected by the sensor, and the system will alert the control room with an alarm and a display showing the pillar number with the issue." This proactive approach will allow authorities to take action before an accident occurs.

Sardar believes that with the necessary support from the government, this technology could be deployed in the metro rail system, greatly enhancing safety measures and ensuring pedestrian safety.

How the System Works
The system is equipped with specialized sensors on each bearing pad. Even slight shifts in the pad will trigger a signal to the control unit, which will display a warning with the corresponding pillar number. A red alert will also sound, and the system can send SMS notifications to mobile phones. The control room will be able to monitor the bearing pad's position in real-time, ensuring swift responses to any changes.

Iran Sardar’s Background and Other Innovations
Iran Sardar, hailing from Gaila village in the Agailjhara Upazila of Barishal, developed an interest in robotics after seeing Sophia the Robot in 2017. He has since gained recognition for his work, winning second place in the Digital Innovation Fair in 2022 for his robot "Corona Sabeck." He has also created robots like "Riba" and "Agni" designed to prevent fire accidents, which gained national attention.

Currently a student at Daffodil International University in the Computing and Information Systems (CIS) department, Iran plans to continue advancing the field of robotics in Bangladesh, aiming to solve technology-related challenges in the country through homegrown innovations.
