The Data Transfer for Event Data Recorder on Internet of Things (EDR-IoT)

Event Data Recorder (EDR) is applied in vehicles to accommodate vehicle safety, accident investigation, and data analysis. Commonly, the EDR stores text, image, video in local storage such as flash memory. The EDR also works standalone. Those conditions cause problems if the EDR is broken in an accident. Therefore, the EDR technology needs an online system where the data storage can be accessed online. It provides a backup system and online monitoring of EDR data. This study proposes a system to accommodate online EDR. It has features such as online data and EDR management based on Internet of Things (IoT) protocol such as MQTT. The publish and subscribe method are applied to manage the interval setting for GPS. The EDR acts as subscriber and the server acts as MQTT broker and publisher. The OpenCV library is applied to detect the passenger and create video of event. The proposed system has been tested and results average delay 1.13 seconds.
